+ introduced in local 2005-03-13 change of `configure.in'. However,
+ do not check for internal `-lber' `ber_pvt_opt_on' symbol as done
+ in upstream. This symbol is not part of any published interface,
+ it may exist or not exist, depending on openldap version. Cryptic
+ comment before using it in upstream 21.5 source did not state
+ precisely under which circumstances checking for it was useful,
+ which sort of user code tried to link the symbol. So in local
+ 21.5 dismissed both the code and the comment without writing a
+ cleaner equivalent.

========================
** Summary of user-visible changes:
-
+ -- Motif is now deprecated on linux and cygwin.
+ -- On UNIX and linux, '--with-widgets=no' is now the default. If
+ you want buffer tabs or the progress bar, you must run configure
+ with the option '--with-widgets=lucid' or a different toolkit.
-- PUI related changes (Package User Interface)
- A minor rearrangement of the "Tools -> Packages" menu.
- Only a single package download site can be selected.
- Python now supported.
- New file extensions recognized: .ss, .pdb, .psw.
-- Fixed ldap libraries configuration.
+ -- Fixed `LDAP_OPT_ON' libraries configuration.
** The delete key now deletes forward by default.
It used to fail when `-lldap' requires `-llber'. Introduced in
upstream `configure.in' revision 1.151.2.31 (2005/01/31 02:54:47 +0).
+*** Fixed `LDAP_OPT_ON' libraries configuration.
+
+The original fix of local `configure.in' revision 1.19 (2004/12/19
+21:10:02 +0) introduced lossage on another class of systems. In some
+openldap versions `ldap_*' functions may link successfully without
+`-lber', but compiling and linking program with `LDAP_OPT_ON' may
+require `-lber'. When configuring ldap libraries, check for such
+systems, and in a cleaner way than in upstream.

* Lisp and internal changes in XEmacs 21.4
==========================================

Olivier Galibert has written a portable dumper for XEmacs, based on

implement correctly and makes XEmacs very hard to port to new
operating systems, or even to new releases of old systems.

between `temacs' and `xemacs'.
-Unfortunately, the portable dumper has not been completely finished

-Argument Lists
-==============
+3.1 Argument Lists
+==================
Emacs Lisp's notation for argument lists of functions is a subset of
the Common Lisp notation. As well as the familiar `&optional' and
Instead, this package defines alternates for several Lisp forms which
you must use if you need Common Lisp argument lists.
- - Special Form: defun* name arglist body...
+ -- Special Form: defun* name arglist body...
This form is identical to the regular `defun' form, except that
ARGLIST is allowed to be a full Common Lisp argument list. Also,
the function body is enclosed in an implicit block called NAME;
*note Blocks and Exits::.
- - Special Form: defsubst* name arglist body...
+ -- Special Form: defsubst* name arglist body...
This is just like `defun*', except that the function that is
defined is automatically proclaimed `inline', i.e., calls to it
may be expanded into in-line code by the byte compiler. This is
processing of keyword arguments, default values, etc., to be done
at compile-time whenever possible.
- - Special Form: defmacro* name arglist body...
+ -- Special Form: defmacro* name arglist body...
This is identical to the regular `defmacro' form, except that
ARGLIST is allowed to be a full Common Lisp argument list. The
`&environment' keyword is supported as described in Steele. The
Emacs Lisp interpreter. The macro expander body is enclosed in an
implicit block called NAME.
- - Special Form: function* symbol-or-lambda
+ -- Special Form: function* symbol-or-lambda
This is identical to the regular `function' form, except that if
the argument is a `lambda' form then that form may use a full
Common Lisp argument list.

-Time of Evaluation
-==================
+3.2 Time of Evaluation
+======================
Normally, the byte-compiler does not actually execute the forms in a
file it compiles. For example, if a file contains `(setq foo t)', the
compiler effectively evaluates `defmacro' forms at compile-time so that
later parts of the file can refer to the macros that are defined.
- - Special Form: eval-when (situations...) forms...
+ -- Special Form: eval-when (situations...) forms...
This form controls when the body FORMS are evaluated. The
SITUATIONS list may contain any set of the symbols `compile',
`load', and `eval' (or their long-winded ANSI equivalents,
`(eval-when (compile load eval) ...)' and so is not itself defined by
this package.
- - Special Form: eval-when-compile forms...
+ -- Special Form: eval-when-compile forms...
The FORMS are evaluated at compile-time; at execution time, this
form acts like a quoted constant of the resulting value. Used at
top-level, `eval-when-compile' is just like `eval-when (compile
This form is similar to the `#.' syntax of true Common Lisp.
- - Special Form: load-time-value form
+ -- Special Form: load-time-value form
The FORM is evaluated at load-time; at execution time, this form
acts like a quoted constant of the resulting value.

makes available in other versions of Emacs.
- - Function: defalias symbol function

-Type Predicates
-===============
+4.1 Type Predicates
+===================
The "CL" package defines a version of the Common Lisp `typep' predicate.
- - Function: typep object type
+ -- Function: typep object type
Check if OBJECT is of type TYPE, where TYPE is a (quoted) type
name of the sort used by Common Lisp. For example, `(typep foo
'integer)' is equivalent to `(integerp foo)'.
The following function and macro (not technically predicates) are
related to `typep'.
- - Function: coerce object type
+ -- Function: coerce object type
This function attempts to convert OBJECT to the specified TYPE.
If OBJECT is already of that type as determined by `typep', it is
simply returned. Otherwise, certain types of conversions will be
integers can be coerced in versions of Emacs that support floats.
In all other circumstances, `coerce' signals an error.
- - Special Form: deftype name arglist forms...
+ -- Special Form: deftype name arglist forms...
This macro defines a new type called NAME. It is similar to
`defmacro' in many ways; when NAME is encountered as a type name,
the body FORMS are evaluated and should return a type specifier
\1f
File: cl.info, Node: Equality Predicates, Prev: Type Predicates, Up: Predicates
-Equality Predicates
-===================
+4.2 Equality Predicates
+=======================
This package defines two Common Lisp predicates, `eql' and `equalp'.
- - Function: eql a b
+ -- Function: eql a b
This function is almost the same as `eq', except that if A and B
are numbers of the same type, it compares them for numeric
equality (as if by `equal' instead of `eq'). This makes a
fact the only known way to distinguish between the two zeros in
Emacs Lisp is to `format' them and check for a minus sign.
- - Function: equalp a b
+ -- Function: equalp a b
This function is a more flexible version of `equal'. In
particular, it compares strings and characters case-insensitively,
and it compares numbers without regard to type (so that `(equalp 3

+5.1 Assignment
+==============
The `psetq' form is just like `setq', except that multiple assignments
are done in parallel rather than sequentially.
- - Special Form: psetq [symbol form]...

This special form (actually a macro) is used to assign to several
variables simultaneously. Given only one SYMBOL and FORM, it has
the same effect as `setq'. Given several SYMBOL and FORM pairs,

-Basic Setf
-----------
+5.2.1 Basic Setf
+----------------
The `setf' macro is the most basic way to operate on generalized
variables.
- - Special Form: setf [place form]...
+ -- Special Form: setf [place form]...
This macro evaluates FORM and stores it in PLACE, which must be a
valid generalized variable form. If there are several PLACE and
FORM pairs, the assignments are done sequentially just as with
\1f
File: cl.info, Node: Modify Macros, Next: Customizing Setf, Prev: Basic Setf, Up: Generalized Variables
-Modify Macros
--------------
+5.2.2 Modify Macros
+-------------------
This package defines a number of other macros besides `setf' that
operate on generalized variables. Many are interesting and useful even
when the PLACE is just a variable name.
- - Special Form: psetf [place form]...
+ -- Special Form: psetf [place form]...
This macro is to `setf' what `psetq' is to `setq': When several
PLACEs and FORMs are involved, the assignments take place in
parallel rather than sequentially. Specifically, all subforms are
evaluated from left to right, then all the assignments are done
(in an undefined order).
- - Special Form: incf place &optional x
+ -- Special Form: incf place &optional x
This macro increments the number stored in PLACE by one, or by X
if specified. The incremented value is returned. For example,
`(incf i)' is equivalent to `(setq i (1+ i))', and `(incf (car x)
As a more Emacs-specific example of `incf', the expression `(incf
(point) N)' is essentially equivalent to `(forward-char N)'.
- - Special Form: decf place &optional x
+ -- Special Form: decf place &optional x
This macro decrements the number stored in PLACE by one, or by X
if specified.
- - Special Form: pop place
+ -- Special Form: pop place
This macro removes and returns the first element of the list stored
in PLACE. It is analogous to `(prog1 (car PLACE) (setf PLACE (cdr
PLACE)))', except that it takes care to evaluate all subforms only
once.
- - Special Form: push x place
+ -- Special Form: push x place
This macro inserts X at the front of the list stored in PLACE. It
is analogous to `(setf PLACE (cons X PLACE))', except for
evaluation of the subforms.
- - Special Form: pushnew x place &key :test :test-not :key
+ -- Special Form: pushnew x place &key :test :test-not :key
This macro inserts X at the front of the list stored in PLACE, but
only if X was not `eql' to any existing element of the list. The
optional keyword arguments are interpreted in the same way as for
`adjoin'. *Note Lists as Sets::.
- - Special Form: shiftf place... newvalue
+ -- Special Form: shiftf place... newvalue
This macro shifts the PLACEs left by one, shifting in the value of
NEWVALUE (which may be any Lisp expression, not just a generalized
variable), and returning the value shifted out of the first PLACE.
except that the subforms of A, B, and C are actually evaluated
only once each and in the apparent order.
- - Special Form: rotatef place...
+ -- Special Form: rotatef place...
This macro rotates the PLACEs left by one in circular fashion.
Thus, `(rotatef A B C D)' is equivalent to
The following macros were invented for this package; they have no
analogues in Common Lisp.
- - Special Form: letf (bindings...) forms...
+ -- Special Form: letf (bindings...) forms...
This macro is analogous to `let', but for generalized variables
rather than just symbols. Each BINDING should be of the form
`(PLACE VALUE)'; the original contents of the PLACEs are saved,
not bound on entry, it is simply made unbound by `makunbound' or
`fmakunbound' on exit.
- - Special Form: letf* (bindings...) forms...
+ -- Special Form: letf* (bindings...) forms...
This macro is to `letf' what `let*' is to `let': It does the
bindings in sequential rather than parallel order.
- - Special Form: callf FUNCTION PLACE ARGS...
+ -- Special Form: callf FUNCTION PLACE ARGS...
This is the "generic" modify macro. It calls FUNCTION, which
should be an unquoted function name, macro name, or lambda. It
passes PLACE and ARGS as arguments, and assigns the result back to
create even more concise notations for modify macros. Note again
that `callf' is an extension to standard Common Lisp.
- - Special Form: callf2 FUNCTION ARG1 PLACE ARGS...
+ -- Special Form: callf2 FUNCTION ARG1 PLACE ARGS...
This macro is like `callf', except that PLACE is the _second_
argument of FUNCTION rather than the first. For example, `(push X
PLACE)' is equivalent to `(callf2 cons X PLACE)'.

File: cl.info, Node: Customizing Setf, Prev: Modify Macros, Up: Generalized Variables
-Customizing Setf
-----------------
+5.2.3 Customizing Setf
+----------------------
Common Lisp defines three macros, `define-modify-macro', `defsetf', and
`define-setf-method', that allow the user to extend generalized
variables in various ways.
- - Special Form: define-modify-macro name arglist function [doc-string]
+ -- Special Form: define-modify-macro name arglist function [doc-string]
This macro defines a "read-modify-write" macro similar to `incf'
and `decf'. The macro NAME is defined to take a PLACE argument
followed by additional arguments described by ARGLIST. The call
`get-setf-method', or consult the source file `cl-macs.el' to see
how to use the internal `setf' building blocks.
- - Special Form: defsetf access-fn update-fn
+ -- Special Form: defsetf access-fn update-fn
This is the simpler of two `defsetf' forms. Where ACCESS-FN is
the name of a function which accesses a place, this declares
UPDATE-FN to be the corresponding store function. From now on,
(defsetf symbol-value set)
(defsetf buffer-name rename-buffer t)
- - Special Form: defsetf access-fn arglist (store-var) forms...
+ -- Special Form: defsetf access-fn arglist (store-var) forms...
This is the second, more complex, form of `defsetf'. It is rather
like `defmacro' except for the additional STORE-VAR argument. The
FORMS should return a Lisp form which stores the value of
(defsetf nth (n x) (store)
(list 'setcar (list 'nthcdr n x) store))
- - Special Form: define-setf-method access-fn arglist forms...
+ -- Special Form: define-setf-method access-fn arglist forms...
This is the most general way to create new place forms. When a
`setf' to ACCESS-FN with arguments described by ARGLIST is
expanded, the FORMS are evaluated and must return a list of five
optimize away most temporaries that turn out to be unnecessary, so
there is little reason for the setf-method itself to optimize.
- - Function: get-setf-method place &optional env
+ -- Function: get-setf-method place &optional env
This function returns the setf-method for PLACE, by invoking the
definition previously recorded by `defsetf' or
`define-setf-method'. The result is a list of five values as

-----------------
+5.3.1 Dynamic Bindings
+----------------------
The standard `let' form binds variables whose names are known at
compile-time. The `progv' form provides an easy way to bind variables
whose names are computed at run-time.
- - Special Form: progv symbols values forms...

This form establishes `let'-style variable bindings on a set of
variables computed at run-time. The expressions SYMBOLS and
VALUES are evaluated, and must return lists of symbols and values,

-Lexical Bindings
-----------------
+5.3.2 Lexical Bindings
+----------------------
The "CL" package defines the following macro which more closely follows
the Common Lisp `let' form:
- - Special Form: lexical-let (bindings...) forms...
+ -- Special Form: lexical-let (bindings...) forms...
This form is exactly like `let' except that the bindings it
establishes are purely lexical. Lexical bindings are similar to
local variables in a language like C: Only the code physically
The `lexical-let' form is an extension to Common Lisp. In true
Common Lisp, all bindings are lexical unless declared otherwise.
- - Special Form: lexical-let* (bindings...) forms...

This form is just like `lexical-let', except that the bindings are
made sequentially in the manner of `let*'.

-Function Bindings
------------------
+5.3.3 Function Bindings
+-----------------------
These forms make `let'-like bindings to functions instead of variables.
- - Special Form: flet (bindings...) forms...
+ -- Special Form: flet (bindings...) forms...
This form establishes `let'-style bindings on the function cells
of symbols rather than on the value cells. Each BINDING must be a
list of the form `(NAME ARGLIST FORMS...)', which defines a
enclosed in an implicit block as if by `defun*'. *Note Program
Structure::.
- - Special Form: labels (bindings...) forms...
+ -- Special Form: labels (bindings...) forms...
The `labels' form is a synonym for `flet'. (In Common Lisp,
`labels' and `flet' differ in ways that depend on their lexical
scoping; these distinctions vanish in dynamically scoped Emacs

-Macro Bindings
---------------
+5.3.4 Macro Bindings
+--------------------
These forms create local macros and "symbol macros."
- - Special Form: macrolet (bindings...) forms...
+ -- Special Form: macrolet (bindings...) forms...
This form is analogous to `flet', but for macros instead of
functions. Each BINDING is a list of the same form as the
arguments to `defmacro*' (i.e., a macro name, argument list, and
that appear physically within the body FORMS, possibly after
expansion of other macros in the body.
- - Special Form: symbol-macrolet (bindings...) forms...
+ -- Special Form: symbol-macrolet (bindings...) forms...
This form creates "symbol macros", which are macros that look like
variable references rather than function calls. Each BINDING is a
list `(VAR EXPANSION)'; any reference to VAR within the body FORMS

+5.4 Conditionals
+================
These conditional forms augment Emacs Lisp's simple `if', `and', `or',
and `cond' forms.
- - Special Form: when test forms...
+ -- Special Form: when test forms...
This is a variant of `if' where there are no "else" forms, and
possibly several "then" forms. In particular,
(if TEST (progn A B C) nil)
- - Special Form: unless test forms...
+ -- Special Form: unless test forms...
This is a variant of `if' where there are no "then" forms, and
possibly several "else" forms:
(when (not TEST) A B C)
- - Special Form: case keyform clause...
+ -- Special Form: case keyform clause...
This macro evaluates KEYFORM, then compares it with the key values
listed in the various CLAUSEs. Whichever clause matches the key
is executed; comparison is done by `eql'. If no clause matches,
((?\r ?\n) (do-ret-thing))
(t (do-other-thing)))
- - Special Form: ecase keyform clause...
+ -- Special Form: ecase keyform clause...
This macro is just like `case', except that if the key does not
match any of the clauses, an error is signalled rather than simply
returning `nil'.
- - Special Form: typecase keyform clause...
+ -- Special Form: typecase keyform clause...
This macro is a version of `case' that checks for types rather
than values. Each CLAUSE is of the form `(TYPE BODY...)'. *Note
Type Predicates::, for a description of type specifiers. For
`otherwise' is also allowed. To make one clause match any of
several types, use an `(or ...)' type specifier.
- - Special Form: etypecase keyform clause...

`return-from' the block.
- - Special Form: block name forms...
+ -- Special Form: block name forms...
The FORMS are evaluated as if by a `progn'. However, if any of
the FORMS execute `(return-from NAME)', they will jump out and
return directly from the `block' form. The `block' returns the
that `do' loops and `defun*' functions which don't use `return'
don't pay the overhead to support it.
- - Special Form: return-from name [result]
+ -- Special Form: return-from name [result]
This macro returns from the block named NAME, which must be an
(unevaluated) symbol. If a RESULT form is specified, it is
evaluated to produce the result returned from the `block'.
Otherwise, `nil' is returned.
- - Special Form: return [result]
+ -- Special Form: return [result]
This macro is exactly like `(return-from nil RESULT)'. Common
Lisp loops like `do' and `dolist' implicitly enclose themselves in
`nil' blocks.

-=========
+5.6 Iteration
+=============
The macros described here provide more sophisticated, high-level
looping constructs to complement Emacs Lisp's basic `while' loop.
- - Special Form: loop forms...
+ -- Special Form: loop forms...
The "CL" package supports both the simple, old-style meaning of
`loop' and the extremely powerful and flexible feature known as
the "Loop Facility" or "Loop Macro". This more advanced facility
the above notation would simply access and throw away the value of
a variable.)
- - Special Form: do (spec...) (end-test [result...]) forms...
+ -- Special Form: do (spec...) (end-test [result...]) forms...
This macro creates a general iterative loop. Each SPEC is of the
form
((or (null x) (null y))
(nreverse z)))
- - Special Form: do* (spec...) (end-test [result...]) forms...
+ -- Special Form: do* (spec...) (end-test [result...]) forms...
This is to `do' what `let*' is to `let'. In particular, the
initial values are bound as if by `let*' rather than `let', and
the steps are assigned as if by `setq' rather than `psetq'.

This is a more specialized loop which iterates across the elements
of a list. LIST should evaluate to a list; the body FORMS are
executed with VAR bound to each element of the list in turn.

surrounded by an implicit `nil' block.
- - Special Form: dotimes (var count [result]) forms...

This is a more specialized loop which iterates a specified number
of times. The body is executed with VAR bound to the integers
from zero (inclusive) to COUNT (exclusive), in turn. Then the
return value for the loop form. The loop is surrounded by an
implicit `nil' block.
- - Special Form: do-symbols (var [obarray [result]]) forms...
+ -- Special Form: do-symbols (var [obarray [result]]) forms...
This loop iterates over all interned symbols. If OBARRAY is
specified and is not `nil', it loops over all symbols in that
obarray. For each symbol, the body FORMS are evaluated with VAR
bound to `nil') to get the return value. The loop is surrounded
by an implicit `nil' block.
- - Special Form: do-all-symbols (var [result]) forms...

The `loop' macro essentially creates a mini-language within Lisp that

the equivalent `while' loops written longhand.

+===================
Common Lisp functions can return zero or more results. Emacs Lisp
functions, by contrast, always return exactly one result. This package
lists instead. The `values' form, for example, is a synonym for `list'
in Emacs.
- - Special Form: multiple-value-bind (var...) values-form forms...
+ -- Special Form: multiple-value-bind (var...) values-form forms...
This form evaluates VALUES-FORM, which must return a list of
values. It then binds the VARs to these respective values, as if
by `let', and then executes the body FORMS. If there are more
VARs than values, the extra VARs are bound to `nil'. If there are
fewer VARs than values, the excess values are ignored.

This macro expands to code which executes FORMS, with the

Common Lisp includes a complex and powerful "declaration" mechanism
that allows you to give the compiler special hints about the types of
Under the earlier non-optimizing compiler, these declarations will
effectively be ignored.
- - Function: proclaim decl-spec
+ -- Function: proclaim decl-spec
This function records a "global" declaration specified by
DECL-SPEC. Since `proclaim' is a function, DECL-SPEC is evaluated
and thus should normally be quoted.
- - Special Form: declaim decl-specs...

This macro is like `proclaim', except that it takes any number of
DECL-SPEC arguments, and the arguments are unevaluated and
unquoted. The `declaim' macro also puts an `(eval-when (compile

This macro is used to make declarations within functions and other

generally at the beginning of any of the many "implicit `progn's"
etc. Currently the only declaration understood by `declare' is
`special'.

In this package, `locally' is no different from `progn'.

+==================
These functions augment the standard Emacs Lisp functions `get' and

functions for working with property lists as first-class data
structures not attached to particular objects.
- - Function: getf place property &optional default

This function scans the list PLACE as if it were a property list,
i.e., a list of alternating property names and values. If an
even-numbered element of PLACE is found which is `eq' to PROPERTY,
When not used as a `setf' form, `getf' is just a regular function
and its PLACE argument can actually be any Lisp expression.

+ -- Function: plusp number
This predicate tests whether NUMBER is positive. It is an error
if the argument is not a number.

+9.2 Numerical Functions
+=======================
These functions perform various arithmetic operations on numbers.
- - Function: abs number
+ -- Function: abs number
This function returns the absolute value of NUMBER. (Newer
versions of Emacs provide this as a built-in function; this package
defines `abs' only for Emacs 18 versions which don't provide it as
a primitive.)
- - Function: expt base power

This function returns BASE raised to the power of NUMBER. (Newer
versions of Emacs provide this as a built-in function; this
package defines `expt' only for Emacs 18 versions which don't

This function returns the Greatest Common Divisor of the arguments.
For one argument, it returns the absolute value of that argument.
For zero arguments, it returns zero.
- - Function: lcm &rest integers

This function returns the Least Common Multiple of the arguments.
For one argument, it returns the absolute value of that argument.
For zero arguments, it returns one.
- - Function: isqrt integer

This function computes the "integer square root" of its integer
argument, i.e., the greatest integer less than or equal to the true
square root of the argument.
- - Function: floor* number &optional divisor

This function implements the Common Lisp `floor' function. It is
called `floor*' to avoid name conflicts with the simpler `floor'
function built-in to Emacs 19.

Emacs Lisp does not support multiple-valued functions.
- - Function: ceiling* number &optional divisor
+ -- Function: ceiling* number &optional divisor
This function implements the Common Lisp `ceiling' function, which
is analogous to `floor' except that it rounds the argument or
quotient of the arguments up toward plus infinity. The remainder
will be between 0 and minus R.
- - Function: truncate* number &optional divisor
+ -- Function: truncate* number &optional divisor
This function implements the Common Lisp `truncate' function,
which is analogous to `floor' except that it rounds the argument
or quotient of the arguments toward zero. Thus it is equivalent
to `floor*' if the argument or quotient is positive, or to
`ceiling*' otherwise. The remainder has the same sign as NUMBER.
- - Function: round* number &optional divisor
+ -- Function: round* number &optional divisor
This function implements the Common Lisp `round' function, which
is analogous to `floor' except that it rounds the argument or
quotient of the arguments to the nearest integer. In the case of
a tie (the argument or quotient is exactly halfway between two
integers), it rounds to the even integer.
- - Function: mod* number divisor
+ -- Function: mod* number divisor
This function returns the same value as the second return value of
`floor'.

This package also provides an implementation of the Common Lisp random
number generator. It uses its own additive-congruential algorithm,
which is much more likely to give statistically clean random numbers
than the simple generators supplied by many operating systems.
- - Function: random* number &optional state
+ -- Function: random* number &optional state
This function returns a random nonnegative number less than
NUMBER, and of the same type (either integer or floating-point).
The STATE argument should be a `random-state' object which holds
defaults to the variable `*random-state*', which contains a
pre-initialized `random-state' object.
- - Variable: *random-state*
+ -- Variable: *random-state*
This variable contains the system "default" `random-state' object,
used for calls to `random*' that do not specify an alternative
state object. Since any number of programs in the Emacs process
sequence generated from this variable will be irreproducible for
all intents and purposes.
- - Function: make-random-state &optional state
+ -- Function: make-random-state &optional state
This function creates or copies a `random-state' object. If STATE
is omitted or `nil', it returns a new copy of `*random-state*'.
This is a copy in the sense that future sequences of calls to
later rerun, it can read the original run's random-state from the
file.

It is typically `2^23-1' or `2^25-1'.

the constants' names.
- - Variable: most-positive-float
+ -- Variable: most-positive-float
This constant equals the largest value a Lisp float can hold. For
those systems whose arithmetic supports infinities, this is the
largest _finite_ value. For IEEE machines, the value is
approximately `1.79e+308'.
- - Variable: most-negative-float
+ -- Variable: most-negative-float
This constant equals the most-negative value a Lisp float can hold.
(It is assumed to be equal to `(- most-positive-float)'.)
- - Variable: least-positive-float
+ -- Variable: least-positive-float
This constant equals the smallest Lisp float value greater than
zero. For IEEE machines, it is about `4.94e-324' if denormals are
supported or `2.22e-308' if not.
- - Variable: least-positive-normalized-float
+ -- Variable: least-positive-normalized-float
This constant equals the smallest _normalized_ Lisp float greater
than zero, i.e., the smallest value for which IEEE denormalization
will not result in a loss of precision. For IEEE machines, this
concept of denormalization and gradual underflow, this constant
will always equal `least-positive-float'.
- - Variable: least-negative-float
+ -- Variable: least-negative-float
This constant is the negative counterpart of
`least-positive-float'.
- - Variable: least-negative-normalized-float
+ -- Variable: least-negative-normalized-float
This constant is the negative counterpart of
`least-positive-normalized-float'.
- - Variable: float-epsilon
+ -- Variable: float-epsilon
This constant is the smallest positive Lisp float that can be added
to 1.0 to produce a distinct value. Adding a smaller number to 1.0
will yield 1.0 again due to roundoff. For IEEE machines, epsilon
is about `2.22e-16'.
- - Variable: float-negative-epsilon
+ -- Variable: float-negative-epsilon
This is the smallest positive value that can be subtracted from
1.0 to produce a distinct value. For IEEE machines, it is about
`1.11e-16'.

-======================
+10.2 Mapping over Sequences
+===========================
These functions "map" the function you specify over the elements of
lists or arrays. They are all variations on the theme of the built-in
function `mapcar'.
- - Function: mapcar* function seq &rest more-seqs
+ -- Function: mapcar* function seq &rest more-seqs
This function calls FUNCTION on successive parallel sets of
elements from its argument sequences. Given a single SEQ argument
it is equivalent to `mapcar'; given N sequences, it calls the
argument. This package's `mapcar*' works as a compatible superset
of both.
- - Function: map result-type function seq &rest more-seqs
+ -- Function: map result-type function seq &rest more-seqs
This function maps FUNCTION over the argument sequences, just like
`mapcar*', but it returns a sequence of type RESULT-TYPE rather
than a list. RESULT-TYPE must be one of the following symbols:
as for `mapcar*'), or `nil' (in which case the results are thrown
away and `map' returns `nil').
- - Function: maplist function list &rest more-lists
+ -- Function: maplist function list &rest more-lists
This function calls FUNCTION on each of its argument lists, then
on the `cdr's of those lists, and so on, until the shortest list
runs out. The results are returned in the form of a list. Thus,
pointers themselves rather than the `car's of the advancing
pointers.
- - Function: mapc function seq &rest more-seqs
+ -- Function: mapc function seq &rest more-seqs
This function is like `mapcar*', except that the values returned
by FUNCTION are ignored and thrown away rather than being
collected into a list. The return value of `mapc' is SEQ, the
first sequence.
- - Function: mapl function list &rest more-lists

This function is like `maplist', except that it throws away the
values returned by FUNCTION.
- - Function: mapcan function seq &rest more-seqs

This function is like `mapcar*', except that it concatenates the
return values (which must be lists) using `nconc', rather than
simply collecting them into a list.
- - Function: mapcon function list &rest more-lists

This function is like `maplist', except that it concatenates the
return values using `nconc'.
- - Function: some predicate seq &rest more-seqs

This function calls PREDICATE on each element of SEQ in turn; if
PREDICATE returns a non-`nil' value, `some' returns that value,
otherwise it returns `nil'. Given several sequence arguments, it
order in which the elements are visited, and on the fact that
mapping stops immediately as soon as PREDICATE returns non-`nil'.
- - Function: every predicate seq &rest more-seqs
+ -- Function: every predicate seq &rest more-seqs
This function calls PREDICATE on each element of the sequence(s)
in turn; it returns `nil' as soon as PREDICATE returns `nil' for
any element, or `t' if the predicate was true for all elements.
- - Function: notany predicate seq &rest more-seqs
+ -- Function: notany predicate seq &rest more-seqs
This function calls PREDICATE on each element of the sequence(s)
in turn; it returns `nil' as soon as PREDICATE returns a non-`nil'
value for any element, or `t' if the predicate was `nil' for all
elements.

on sequences.
- - Function: subseq sequence start &optional end
+ -- Function: subseq sequence start &optional end
This function returns a given subsequence of the argument
SEQUENCE, which may be a list, string, or vector. The indices
START and END must be in range, and START must be no greater than
of elements with elements from another sequence. The replacement
is done as if by `replace', described below.
- - Function: concatenate result-type &rest seqs
+ -- Function: concatenate result-type &rest seqs
This function concatenates the argument sequences together to form
a result sequence of type RESULT-TYPE, one of the symbols
`vector', `string', or `list'. The arguments are always copied,
even in cases such as `(concatenate 'list '(1 2 3))' where the
result is identical to an argument.
- - Function: fill seq item &key :start :end

This function fills the elements of the sequence (or the specified
part of the sequence) with the value ITEM.
- - Function: replace seq1 seq2 &key :start1 :end1 :start2 :end2
+ -- Function: replace seq1 seq2 &key :start1 :end1 :start2 :end2
This function copies part of SEQ2 into part of SEQ1. The sequence
SEQ1 is not stretched or resized; the amount of data copied is
simply the shorter of the source and destination (sub)sequences.
share storage but are not `eq', and the start and end arguments
specify overlapping regions, the effect is undefined.
- - Function: remove* item seq &key :test :test-not :key :count :start

:end :from-end
This returns a copy of SEQ with all elements matching ITEM
removed. The result may share storage with or be `eq' to SEQ in
sequence rather than the beginning (this matters only if COUNT was
also specified).
- - Function: delete* item seq &key :test :test-not :key :count :start
+ -- Function: delete* item seq &key :test :test-not :key :count :start
:end :from-end
This deletes all elements of SEQ which match ITEM. It is a
destructive operation. Since Emacs Lisp does not support
The predicate-oriented functions `remove-if', `remove-if-not',
`delete-if', and `delete-if-not' are defined similarly.
- - Function: delete item list
+ -- Function: delete item list
This MacLisp-compatible function deletes from LIST all elements
which are `equal' to ITEM. The `delete' function is built-in to
Emacs 19; this package defines it equivalently in Emacs 18.
- - Function: remove item list
+ -- Function: remove item list
This function removes from LIST all elements which are `equal' to
ITEM. This package defines it for symmetry with `delete', even
though `remove' is not built-in to Emacs 19.
- - Function: remq item list
+ -- Function: remq item list
This function removes from LIST all elements which are `eq' to
ITEM. This package defines it for symmetry with `delq', even
though `remq' is not built-in to Emacs 19.
- - Function: remove-duplicates seq &key :test :test-not :key :start
+ -- Function: remove-duplicates seq &key :test :test-not :key :start
:end :from-end
This function returns a copy of SEQ with duplicate elements
removed. Specifically, if two elements from the sequence match
specified, only elements within that subsequence are examined or
removed.
- - Function: delete-duplicates seq &key :test :test-not :key :start
+ -- Function: delete-duplicates seq &key :test :test-not :key :start
:end :from-end
This function deletes duplicate elements from SEQ. It is a
destructive version of `remove-duplicates'.
- - Function: substitute new old seq &key :test :test-not :key :count
+ -- Function: substitute new old seq &key :test :test-not :key :count
:start :end :from-end
This function returns a copy of SEQ, with all elements matching
OLD replaced with NEW. The `:count', `:start', `:end', and
`:from-end' arguments may be used to limit the number of
substitutions made.
- - Function: nsubstitute new old seq &key :test :test-not :key :count

(See also `member*' and `assoc*'; *note Lists::.)
- - Function: find item seq &key :test :test-not :key :start :end
+ -- Function: find item seq &key :test :test-not :key :start :end
:from-end
This function searches SEQ for an element matching ITEM. If it
finds a match, it returns the matching element. Otherwise, it
`:start' and `:end' arguments may be used to limit the range of
elements that are searched.
- - Function: position item seq &key :test :test-not :key :start :end
+ -- Function: position item seq &key :test :test-not :key :start :end
:from-end
This function is like `find', except that it returns the integer
position in the sequence of the matching item rather than the item
a whole, even if `:start' is non-zero. The function returns `nil'
if no matching element was found.
- - Function: count item seq &key :test :test-not :key :start :end
+ -- Function: count item seq &key :test :test-not :key :start :end
This function returns the number of elements of SEQ which match
ITEM. The result is always a nonnegative integer.
The `find-if', `find-if-not', `position-if', `position-if-not',
`count-if', and `count-if-not' functions are defined similarly.
- - Function: mismatch seq1 seq2 &key :test :test-not :key :start1 :end1
- :start2 :end2 :from-end
+ -- Function: mismatch seq1 seq2 &key :test :test-not :key :start1

This function compares the specified parts of SEQ1 and SEQ2. If
they are the same length and the corresponding elements match

-Sorting Sequences
-=================
+10.5 Sorting Sequences
+======================
- - Function: sort* seq predicate &key :key

This function sorts SEQ into increasing order as determined by
using PREDICATE to compare pairs of elements. PREDICATE should
return true (non-`nil') if and only if its first argument is less
The `sort*' function is destructive; it sorts lists by actually
rearranging the `cdr' pointers in suitable fashion.
- - Function: stable-sort seq predicate &key :key
+ -- Function: stable-sort seq predicate &key :key
This function sorts SEQ "stably", meaning two elements which are
equal in terms of PREDICATE are guaranteed not to be rearranged
out of their original order by the sort.
However, this package reserves the right to use non-stable methods
for `sort*' in the future.
- - Function: merge type seq1 seq2 predicate &key :key
+ -- Function: merge type seq1 seq2 predicate &key :key
This function merges two sequences SEQ1 and SEQ2 by interleaving
their elements. The result sequence, of type TYPE (in the sense
of `concatenate'), has length equal to the sum of the lengths of

-List Functions
-==============
+11.1 List Functions
+===================
This section describes a number of simple operations on lists, i.e.,
chains of cons cells.
- - Function: caddr x
+ -- Function: caddr x
This function is equivalent to `(car (cdr (cdr X)))'. Likewise,
this package defines all 28 `cXXXr' functions where XXX is up to
four `a's and/or `d's. All of these functions are `setf'-able,
and calls to them are expanded inline by the byte-compiler for
maximum efficiency.
- - Function: first x
+ -- Function: first x
This function is a synonym for `(car X)'. Likewise, the functions
`second', `third', ..., through `tenth' return the given element
of the list X.
- - Function: rest x
+ -- Function: rest x
This function is a synonym for `(cdr X)'.
- - Function: endp x
+ -- Function: endp x
Common Lisp defines this function to act like `null', but
signalling an error if `x' is neither a `nil' nor a cons cell.
This package simply defines `endp' as a synonym for `null'.
- - Function: list-length x
+ -- Function: list-length x
This function returns the length of list X, exactly like `(length
X)', except that if X is a circular list (where the cdr-chain
forms a loop rather than terminating with `nil'), this function
returns `nil'. (The regular `length' function would get stuck if
given a circular list.)
- - Function: last x &optional n
+ -- Function: last x &optional n
This function returns the last cons, or the Nth-to-last cons, of
the list X. If N is omitted it defaults to 1. The "last cons"
means the first cons cell of the list whose `cdr' is not another
`nil'.) This function returns `nil' if X is `nil' or shorter than
N. Note that the last _element_ of the list is `(car (last X))'.
- - Function: butlast x &optional n
+ -- Function: butlast x &optional n
This function returns the list X with the last element, or the
last N elements, removed. If N is greater than zero it makes a
copy of the list so as not to damage the original list. In
general, `(append (butlast X N) (last X N))' will return a list
equal to X.
- - Function: nbutlast x &optional n
+ -- Function: nbutlast x &optional n
This is a version of `butlast' that works by destructively
modifying the `cdr' of the appropriate element, rather than making
a copy of the list.
- - Function: list* arg &rest others
+ -- Function: list* arg &rest others
This function constructs a list of its arguments. The final
argument becomes the `cdr' of the last cell constructed. Thus,
`(list* A B C)' is equivalent to `(cons A (cons B C))', and
it is not a name invented for this package like `member*' or
`defun*'.)
- - Function: ldiff list sublist
+ -- Function: ldiff list sublist
If SUBLIST is a sublist of LIST, i.e., is `eq' to one of the cons
cells of LIST, then this function returns a copy of the part of
LIST up to but not including SUBLIST. For example, `(ldiff x
result is a copy; the original LIST is not modified. If SUBLIST
is not a sublist of LIST, a copy of the entire LIST is returned.
- - Function: copy-list list
+ -- Function: copy-list list
This function returns a copy of the list LIST. It copies dotted
lists like `(1 2 . 3)' correctly.
- - Function: copy-tree x &optional vecp
+ -- Function: copy-tree x &optional vecp
This function returns a copy of the tree of cons cells X. Unlike
`copy-sequence' (and its alias `copy-list'), which copies only
along the `cdr' direction, this function copies (recursively)
VECP argument is true, this function copies vectors (recursively)
as well as cons cells.
- - Function: tree-equal x y &key :test :test-not :key
+ -- Function: tree-equal x y &key :test :test-not :key
This function compares two trees of cons cells. If X and Y are
both cons cells, their `car's and `cdr's are compared recursively.
If neither X nor Y is a cons cell, they are compared by `eql', or

-Substitution of Expressions
-===========================
+11.2 Substitution of Expressions
+================================
These functions substitute elements throughout a tree of cons cells.
(*Note Sequence Functions::, for the `substitute' function, which works
on just the top-level elements of a list.)
- - Function: subst new old tree &key :test :test-not :key
+ -- Function: subst new old tree &key :test :test-not :key
This function substitutes occurrences of OLD with NEW in TREE, a
tree of cons cells. It returns a substituted tree, which will be
a copy except that it may share storage with the argument TREE in
test (`eql' by default). The `:key' function is applied to the
elements of the tree but not to OLD.
- - Function: nsubst new old tree &key :test :test-not :key
+ -- Function: nsubst new old tree &key :test :test-not :key
This function is like `subst', except that it works by destructive
modification (by `setcar' or `setcdr') rather than copying.
The `subst-if', `subst-if-not', `nsubst-if', and `nsubst-if-not'
functions are defined similarly.
- - Function: sublis alist tree &key :test :test-not :key
+ -- Function: sublis alist tree &key :test :test-not :key
This function is like `subst', except that it takes an association
list ALIST of OLD-NEW pairs. Each element of the tree (after
applying the `:key' function, if any), is compared with the `car's
of ALIST; if it matches, it is replaced by the corresponding `cdr'.
- - Function: nsublis alist tree &key :test :test-not :key
+ -- Function: nsublis alist tree &key :test :test-not :key
This is a destructive version of `sublis'.

-Lists as Sets
-=============
+11.3 Lists as Sets
+==================
These functions perform operations on lists which represent sets of
elements.
- - Function: member item list
+ -- Function: member item list
This MacLisp-compatible function searches LIST for an element
which is `equal' to ITEM. The `member' function is built-in to
Emacs 19; this package defines it equivalently in Emacs 18. See
the following function for a Common-Lisp compatible version.
- - Function: member* item list &key :test :test-not :key
+ -- Function: member* item list &key :test :test-not :key
This function searches LIST for an element matching ITEM. If a
match is found, it returns the cons cell whose `car' was the
matching element. Otherwise, it returns `nil'. Elements are
The `member-if' and `member-if-not' functions analogously search for
elements which satisfy a given predicate.
- - Function: tailp sublist list
+ -- Function: tailp sublist list
This function returns `t' if SUBLIST is a sublist of LIST, i.e.,
if SUBLIST is `eql' to LIST or to any of its `cdr's.
- - Function: adjoin item list &key :test :test-not :key
+ -- Function: adjoin item list &key :test :test-not :key
This function conses ITEM onto the front of LIST, like `(cons ITEM
LIST)', but only if ITEM is not already present on the list (as
determined by `member*'). If a `:key' argument is specified, it
search, on the reasoning that ITEM is "about" to become part of
the list.
- - Function: union list1 list2 &key :test :test-not :key
+ -- Function: union list1 list2 &key :test :test-not :key
This function combines two lists which represent sets of items,
returning a list that represents the union of those two sets. The
result list will contain all items which appear in LIST1 or LIST2,
result list. The order of elements in the result list is also
undefined.
- - Function: nunion list1 list2 &key :test :test-not :key
+ -- Function: nunion list1 list2 &key :test :test-not :key
This is a destructive version of `union'; rather than copying, it
tries to reuse the storage of the argument lists if possible.
- - Function: intersection list1 list2 &key :test :test-not :key
+ -- Function: intersection list1 list2 &key :test :test-not :key
This function computes the intersection of the sets represented by
LIST1 and LIST2. It returns the list of items which appear in
both LIST1 and LIST2.
- - Function: nintersection list1 list2 &key :test :test-not :key
+ -- Function: nintersection list1 list2 &key :test :test-not :key
This is a destructive version of `intersection'. It tries to
reuse storage of LIST1 rather than copying. It does _not_ reuse
the storage of LIST2.
- - Function: set-difference list1 list2 &key :test :test-not :key
+ -- Function: set-difference list1 list2 &key :test :test-not :key
This function computes the "set difference" of LIST1 and LIST2,
i.e., the set of elements that appear in LIST1 but _not_ in LIST2.
- - Function: nset-difference list1 list2 &key :test :test-not :key
+ -- Function: nset-difference list1 list2 &key :test :test-not :key
This is a destructive `set-difference', which will try to reuse
LIST1 if possible.
- - Function: set-exclusive-or list1 list2 &key :test :test-not :key
+ -- Function: set-exclusive-or list1 list2 &key :test :test-not :key
This function computes the "set exclusive or" of LIST1 and LIST2,
i.e., the set of elements that appear in exactly one of LIST1 and
LIST2.
- - Function: nset-exclusive-or list1 list2 &key :test :test-not :key
+ -- Function: nset-exclusive-or list1 list2 &key :test :test-not :key
This is a destructive `set-exclusive-or', which will try to reuse
LIST1 and LIST2 if possible.
- - Function: subsetp list1 list2 &key :test :test-not :key
+ -- Function: subsetp list1 list2 &key :test :test-not :key
This function checks whether LIST1 represents a subset of LIST2,
i.e., whether every element of LIST1 also appears in LIST2.

-Association Lists
-=================
+11.4 Association Lists
+======================
An "association list" is a list representing a mapping from one set of
values to another; any list whose elements are cons cells is an
association list.
- - Function: assoc* item a-list &key :test :test-not :key
+ -- Function: assoc* item a-list &key :test :test-not :key
This function searches the association list A-LIST for an element
whose `car' matches (in the sense of `:test', `:test-not', and
`:key', or by comparison with `eql') a given ITEM. It returns the
`assoc' ignores `nil's but considers any other non-cons elements
of A-LIST to be an error.)
- - Function: rassoc* item a-list &key :test :test-not :key
+ -- Function: rassoc* item a-list &key :test :test-not :key
This function searches for an element whose `cdr' matches ITEM.
If A-LIST represents a mapping, this applies the inverse of the
mapping to ITEM.
- - Function: rassoc item a-list
+ -- Function: rassoc item a-list
This function searches like `rassoc*' with a `:test' argument of
`equal'. It is analogous to Emacs Lisp's standard `assoc'
function, which derives from the MacLisp rather than the Common
Two simple functions for constructing association lists are:
- - Function: acons key value alist
+ -- Function: acons key value alist
This is equivalent to `(cons (cons KEY VALUE) ALIST)'.
- - Function: pairlis keys values &optional alist
+ -- Function: pairlis keys values &optional alist
This is equivalent to `(nconc (mapcar* 'cons KEYS VALUES) ALIST)'.

idea for them to include side-effects.
- - Special Form: assert test-form [show-args string args...]
+ -- Special Form: assert test-form [show-args string args...]
This form verifies that TEST-FORM is true (i.e., evaluates to a
non-`nil' value). If so, it returns `nil'. If the test is not
satisfied, `assert' signals an error.
Common Lisp, the second argument gives a list of PLACES which can
be `setf''d by the user before continuing from the error.
- - Special Form: check-type place type &optional string

some of the syntax highlighting capabilities into C would make a

+ difference." Wrong idea, I think. When processing one 400kB file
a particular low-level routine was being called 40 _million_ times
simply for _one_ call to `newline-and-indent'. Syntax
highlighting needs to be rewritten to use a reliable, fast parser,
directory _at compile time_. The non-obvious C rule is that
`#include "..."' means to search for the included file in the same
directory as the including file, _not_ in the current directory.
+ Normally this is not a problem but when building with `--srcdir',
+ `make' will search the `VPATH' for you, while the C compiler knows
+ nothing about it.
* Header files should _not_ include `<config.h>' and `"lisp.h"'. It
is the responsibility of the `.c' files that use it to do so.

scanner to determine that no second character is needed to terminate
the comment.
+ There used to be a syntax class `Sextword'. A character of
+`Sextword' class is a word-constituent but a word boundary may exist
+between two such characters. Ken'ichi HANDA <handa@etl.go.jp> explains
+the purpose of the Sextword syntax category:
+
+ Japanese words are not separated by spaces, which makes finding
+ word boundaries very difficult. Theoretically it's impossible
+ without using natural language processing techniques. But, by
+ defining pseudo-words as below (much simplified for letting you
+ understand it easily) for Japanese, we can have a convenient
+ forward-word function for Japanese.
+
+ A Japanese word is a sequence of characters that consists of
+ zero or more Kanji characters followed by zero or more
+ Hiragana characters.
+
+ Then, the problem is that now we can't say that a sequence of
+ word-constituents makes up a word. For instance, both Hiragana "A"
+ and Kanji "KAN" are word-constituents but the sequence of these two
+ letters can't be a single word.
+
+ So, we introduced Sextword for Japanese letters.
+
+ There seems to have been some controversy about this category, as it
+has been removed, readded, and removed again. Currently neither GNU
+Emacs (21.3.99) nor XEmacs (21.5.17) seems to use it.

MACHINE CODE:
-
+
The machine code consists of a vector of 32-bit words.
The first such word specifies the start of the EOF section of the code;
this is the code executed to handle any stuff that needs to be done
(e.g. designating back to ASCII and left-to-right mode) after all
other encoded/decoded data has been written out. This is not used for
charset CCL programs.

+19.3 Lstream Functions
+======================
- - Function: Lstream * Lstream_new (Lstream_implementation *IMP, const
+ -- Function: Lstream * Lstream_new (Lstream_implementation *IMP, const
char *MODE)
Allocate and return a new Lstream. This function is not really
meant to be called directly; rather, each stream type should
provide its own stream creation function, which creates the stream
and does any other necessary creation stuff (e.g. opening a file).
- - Function: void Lstream_set_buffering (Lstream *LSTR,
+ -- Function: void Lstream_set_buffering (Lstream *LSTR,
Lstream_buffering BUFFERING, int BUFFERING_SIZE)
Change the buffering of a stream. See `lstream.h'. By default the
buffering is `STREAM_BLOCK_BUFFERED'.
- - Function: int Lstream_flush (Lstream *LSTR)
+ -- Function: int Lstream_flush (Lstream *LSTR)
Flush out any pending unwritten data in the stream. Clear any
buffered input data. Returns 0 on success, -1 on error.
- - Macro: int Lstream_putc (Lstream *STREAM, int C)
+ -- Macro: int Lstream_putc (Lstream *STREAM, int C)
Write out one byte to the stream. This is a macro and so it is
very efficient. The C argument is only evaluated once but the
STREAM argument is evaluated more than once. Returns 0 on
success, -1 on error.
- - Macro: int Lstream_getc (Lstream *STREAM)
+ -- Macro: int Lstream_getc (Lstream *STREAM)
Read one byte from the stream. This is a macro and so it is very
efficient. The STREAM argument is evaluated more than once.
Return value is -1 for EOF or error.
- - Macro: void Lstream_ungetc (Lstream *STREAM, int C)
+ -- Macro: void Lstream_ungetc (Lstream *STREAM, int C)
Push one byte back onto the input queue. This will be the next
byte read from the stream. Any number of bytes can be pushed back
and will be read in the reverse order they were pushed back--most
and so it is very efficient. The C argument is only evaluated
once but the STREAM argument is evaluated more than once.
- - Function: int Lstream_fputc (Lstream *STREAM, int C)
- - Function: int Lstream_fgetc (Lstream *STREAM)
- - Function: void Lstream_fungetc (Lstream *STREAM, int C)
+ -- Function: int Lstream_fputc (Lstream *STREAM, int C)
+ -- Function: int Lstream_fgetc (Lstream *STREAM)
+ -- Function: void Lstream_fungetc (Lstream *STREAM, int C)
Function equivalents of the above macros.
- - Function: ssize_t Lstream_read (Lstream *STREAM, void *DATA, size_t
+ -- Function: ssize_t Lstream_read (Lstream *STREAM, void *DATA, size_t
SIZE)
Read SIZE bytes of DATA from the stream. Return the number of
bytes read. 0 means EOF. -1 means an error occurred and no bytes
were read.
- - Function: ssize_t Lstream_write (Lstream *STREAM, void *DATA, size_t
- SIZE)
+ -- Function: ssize_t Lstream_write (Lstream *STREAM, void *DATA,
+ size_t SIZE)
Write SIZE bytes of DATA to the stream. Return the number of
bytes written. -1 means an error occurred and no bytes were
written.
- - Function: void Lstream_unread (Lstream *STREAM, void *DATA, size_t
+ -- Function: void Lstream_unread (Lstream *STREAM, void *DATA, size_t
SIZE)
Push back SIZE bytes of DATA onto the input queue. The next call
to `Lstream_read()' with the same size will read the same bytes
back. Note that this will be the case even if there is other
pending unread data.
- - Function: int Lstream_close (Lstream *STREAM)
+ -- Function: int Lstream_close (Lstream *STREAM)
Close the stream. All data will be flushed out.
- - Function: void Lstream_reopen (Lstream *STREAM)
+ -- Function: void Lstream_reopen (Lstream *STREAM)
Reopen a closed stream. This enables I/O on it again. This is not
meant to be called except from a wrapper routine that reinitializes
variables and such--the close routine may well have freed some
necessary storage structures, for example.
- - Function: void Lstream_rewind (Lstream *STREAM)
+ -- Function: void Lstream_rewind (Lstream *STREAM)
Rewind the stream to the beginning.

+====================
- - Lstream Method: ssize_t reader (Lstream *STREAM, unsigned char

*DATA, size_t SIZE)
Read some data from the stream's end and store it into DATA, which
can hold SIZE bytes. Return the number of bytes read. A return
This function can be `NULL' if the stream is output-only.
- - Lstream Method: ssize_t writer (Lstream *STREAM, const unsigned char
- *DATA, size_t SIZE)
+ -- Lstream Method: ssize_t writer (Lstream *STREAM, const unsigned
+ char *DATA, size_t SIZE)
Send some data to the stream's end. Data to be sent is in DATA
and is SIZE bytes. Return the number of bytes sent. This
function can send and return fewer bytes than is passed in; in that
descriptor and are getting `EWOULDBLOCK' errors.) This function
can be `NULL' if the stream is input-only.
- - Lstream Method: int rewinder (Lstream *STREAM)
+ -- Lstream Method: int rewinder (Lstream *STREAM)
Rewind the stream. If this is `NULL', the stream is not seekable.
- - Lstream Method: int seekable_p (Lstream *STREAM)
+ -- Lstream Method: int seekable_p (Lstream *STREAM)
Indicate whether this stream is seekable--i.e. it can be rewound.
This method is ignored if the stream does not have a rewind
method. If this method is not present, the result is determined
by whether a rewind method is present.
- - Lstream Method: int flusher (Lstream *STREAM)
+ -- Lstream Method: int flusher (Lstream *STREAM)
Perform any additional operations necessary to flush the data in
this stream.
- - Lstream Method: int pseudo_closer (Lstream *STREAM)
+ -- Lstream Method: int pseudo_closer (Lstream *STREAM)
- - Lstream Method: int closer (Lstream *STREAM)
+ -- Lstream Method: int closer (Lstream *STREAM)
Perform any additional operations necessary to close this stream
down. May be `NULL'. This function is called when
`Lstream_close()' is called or when the stream is
garbage-collected. When this function is called, all pending data
in the stream will already have been written out.
- - Lstream Method: Lisp_Object marker (Lisp_Object LSTREAM, void
+ -- Lstream Method: Lisp_Object marker (Lisp_Object LSTREAM, void
(*MARKFUN) (Lisp_Object))
Mark this object for garbage collection. Same semantics as a
standard `Lisp_Object' marker. This function can be `NULL'.

A Lisp "library" is a single loadable file containing Lisp code. It
may be in source or byte-compiled form. A Lisp "package" is a set of
one or more libraries, usually related to each other in some way,
bundled with administrative information for convenient distribution.

- - Function: char-int character
+ -- Function: char-int character
This function converts a character into an equivalent integer.
The resulting integer will always be non-negative. The integers in
the range 0 - 255 map to characters as follows:
XEmacs, the order in which character sets were loaded, etc., and
you should not depend on them.
- - Function: int-char integer
+ -- Function: int-char integer
This function converts an integer into the equivalent character.
Not all integers correspond to valid characters; use `char-int-p'
to determine whether this is the case. If the integer cannot be
converted, `nil' is returned.
- - Function: char-int-p object
+ -- Function: char-int-p object
This function returns `t' if OBJECT is an integer that can be
converted into a character.
- - Function: char-or-char-int-p object
+ -- Function: char-or-char-int-p object
This function returns `t' if OBJECT is a character or an integer
that can be converted into one.

-====
+14.2 Eval
+=========
Most often, forms are evaluated automatically, by virtue of their
occurrence in a program being run. On rare occasions, you may need to
specify limits to the evaluation process, or record recently returned
values. Loading a file also does evaluation (*note Loading::).
- - Function: eval form
+ -- Function: eval form
This is the basic function for performing evaluation. It evaluates
FORM in the current environment and returns the result. How the
evaluation proceeds depends on the type of the object (*note
The number of currently active calls to `eval' is limited to
`max-lisp-eval-depth' (see below).
- - Command: eval-region start end &optional stream
+ -- Command: eval-region start end &optional stream
This function evaluates the forms in the current buffer in the
region defined by the positions START and END. It reads forms from
the region and calls `eval' on them until the end of the region is
`eval-region' always returns `nil'.
- - Command: eval-buffer buffer &optional stream
+ -- Command: eval-buffer buffer &optional stream
This is like `eval-region' except that it operates on the whole
contents of BUFFER.
- - Variable: max-lisp-eval-depth
+ -- Variable: max-lisp-eval-depth
This variable defines the maximum depth allowed in calls to `eval',
`apply', and `funcall' before an error is signaled (with error
message `"Lisp nesting exceeds max-lisp-eval-depth"'). This counts
function call arguments and function body forms.
This limit, with the associated error when it is exceeded, is one

form `setq'. When you need to compute the choice of variable at run
time, use the function `set'.
- - Special Form: setq [symbol form]...
+ -- Special Form: setq [symbol form]...
This special form is the most common method of changing a
variable's value. Each SYMBOL is given a new value, which is the
result of evaluating the corresponding FORM. The most-local
y (1+ x)) ; the value of `y' is computed.
=> 11
- - Function: set symbol value
+ -- Function: set symbol value
This function sets SYMBOL's value to VALUE, then returns VALUE.
Since `set' is a function, the expression written for SYMBOL is
evaluated to obtain the symbol to set.
One other function for setting a variable is designed to add an
element to a list if it is not already present in the list.
- - Function: add-to-list symbol element
+ -- Function: add-to-list symbol element
This function sets the variable SYMBOL by consing ELEMENT onto the
old value, if ELEMENT is not already a member of that value. It
returns the resulting list, whether updated or not. The value of
(setq foo '(a b))
=> (a b)
-
+
(add-to-list 'foo 'c) ;; Add `c'.
=> (c a b)
-
+
(add-to-list 'foo 'b) ;; No effect.
=> (c a b)
-
+
foo ;; `foo' was changed.

-What Is a Function?
-===================
+17.1 What Is a Function?
+========================
In a general sense, a function is a rule for carrying on a computation
given several values called "arguments". The result of the computation
specifically to mean a function written in Lisp. Special forms and
macros are not functions.
+"command"
+ A "command" is a possible definition for a key sequence--we count
+ mouse events and menu accesses as key sequences for this purpose.
+ More formally, within XEmacs lisp, a command is something that
+ `command-execute' can invoke.
+
+ Some functions are commands; a function written in Lisp is a
+ command if it contains an interactive declaration. A trivial
+ interactive declaration is a line `(interactive)' immediately
+ after the documentation string. For more complex examples, with
+ prompting and completion, see *Note Defining Commands::. Such a
+ function can be called from Lisp expressions like other functions;
+ in this case, the fact that the function is a command makes no
+ difference.
+
+ Keyboard macros (strings and vectors) are commands also, even
+ though they are not functions. A symbol is a command if its
+ function definition is a command; such symbols can be invoked with
+ `M-x'. The symbol is a function as well if the definition is a
+ function.
+
+ In the case where you want to call a command in reaction to a
+ user-generated event, you'll need to bind it to that event. For
+ how to do this, see *Note Key Binding Commands::. *Note Command
+ Overview::.
+
+"keystroke command"
+ A "keystroke command" is a command that is bound to a key sequence
+ (typically one to three keystrokes). The distinction is made here
+ merely to avoid confusion with the meaning of "command" in
+ non-Emacs editors; for Lisp programs, the distinction is normally
+ unimportant.
+
"primitive"
A "primitive" is a function callable from Lisp that is written in
C, such as `car' or `append'. These functions are also called
programmers to do the sorts of things that special forms can do.
*Note Macros::, for how to define and use macros.
-"command"
- A "command" is an object that `command-execute' can invoke; it is
- a possible definition for a key sequence. Some functions are

- unimportant.
-
"compiled function"
A "compiled function" is a function that has been compiled by the
byte compiler. *Note Compiled-Function Type::.
- - Function: subrp object
+ -- Function: subrp object
This function returns `t' if OBJECT is a built-in function (i.e.,
a Lisp primitive).
(subrp (symbol-function 'message))
=> t
- - Function: compiled-function-p object
+ -- Function: compiled-function-p object
This function returns `t' if OBJECT is a compiled function. For

-Calling Functions
-=================
+17.5 Calling Functions
+======================
Defining functions is only half the battle. Functions don't do
anything until you "call" them, i.e., tell them to run. Calling a
run time which function to call. To do that, use the functions
`funcall' and `apply'.
- - Function: funcall function &rest arguments
+ -- Function: funcall function &rest arguments
`funcall' calls FUNCTION with ARGUMENTS, and returns whatever
FUNCTION returns.
Compare these example with the examples of `apply'.
- - Function: apply function &rest arguments
+ -- Function: apply function &rest arguments
`apply' calls FUNCTION with ARGUMENTS, just like `funcall' but
with one difference: the last of ARGUMENTS is a list of arguments
to give to FUNCTION, rather than a single argument. We also say

=> 10

function:

This function returns ARG and has no side effects.
- - Command: ignore &rest args

This function ignores any arguments and returns `nil'.

A "mapping function" applies a given function to each element of a list

Mapping functions should never modify the sequence being mapped over.
The results are unpredictable.

(mapcar 'car '((a b) (c d) (e f)))
=> (a c e)
(mapcar '1+ [1 2 3])
=> (2 3 4)
(mapcar 'char-to-string "abc")
=> ("a" "b" "c")
-
+
;; Call each function in `my-hooks'.
(mapcar 'funcall my-hooks)
-
+
(defun mapcar* (f &rest args)
"Apply FUNCTION to successive cars of all ARGS.
Return the list of results."
(apply 'mapcar* f
;; Recurse for rest of elements.
(mapcar 'cdr args)))))
-
+
(mapcar* 'cons '(a b c) '(1 2 3 4))
=> ((a . 1) (b . 2) (c . 3))
- - Function: mapconcat function sequence separator
+ -- Function: mapconcat function sequence separator
`mapconcat' applies FUNCTION to each element of SEQUENCE: the
results, which must be strings, are concatenated. Between each
pair of result strings, `mapconcat' inserts the string SEPARATOR.
'(The cat in the hat)
" ")
=> "The cat in the hat"

In Lisp, a function is a list that starts with `lambda', a byte-code
function compiled from such a list, or alternatively a primitive
In such cases, we usually use the special form `function' instead of
simple quotation to quote the anonymous function.
- - Special Form: function function-object

This special form returns FUNCTION-OBJECT without evaluating it.
In this, it is equivalent to `quote'. However, it serves as a

File: lispref.info, Node: How Programs Do Loading, Next: Autoload, Up: Loading
-How Programs Do Loading
-=======================
+20.1 How Programs Do Loading
+============================
XEmacs Lisp has several interfaces for loading. For example,
`autoload' creates a placeholder object for a function in a file;
if it isn't already loaded (*note Named Features::). Ultimately, all
these facilities call the `load' function to do the work.
- - Function: load filename &optional missing-ok nomessage nosuffix
+ -- Function: load filename &optional missing-ok nomessage nosuffix
This function finds and opens a file of Lisp code, evaluates all
the forms in it, and closes the file.
`load' returns `t' if the file loads successfully.
- - User Option: load-path
+ -- User Option: load-path
The value of this variable is a list of directories to search when
loading files with `load'. Each element is a string (which must be
a directory name) or `nil' (which stands for the current working
should bind `load-path' locally with `let' around the calls to
`load'.
- - Function: locate-file filename path-list &optional suffixes mode
+ -- Function: locate-file filename path-list &optional suffixes mode
This function searches for a file in the same way that `load' does,
and returns the file found (if any). (In fact, `load' uses this
function to search through `load-path'.) It searches for FILENAME
you will have to call `locate-file-clear-hashing' to get it back
on track. See that function for details.
- - Function: locate-file-clear-hashing path
+ -- Function: locate-file-clear-hashing path
This function clears the hash records for the specified list of
directories. `locate-file' uses a hashing scheme to speed lookup,
and will correctly track the following environmental changes:
the directory list. In this case, you must call
`locate-file-clear-hashing'.
- - Variable: load-in-progress
+ -- Variable: load-in-progress
This variable is non-`nil' if Emacs is in the process of loading a
file, and it is `nil' otherwise.
- - Variable: load-read-function
+ -- Variable: load-read-function
This variable specifies an alternate expression-reading function
for `load' and `eval-region' to use instead of `read'. The
function should accept one argument, just as `read' does.
Normally, the variable's value is `nil', which means those
functions should use `read'.
- - User Option: load-warn-when-source-newer
+ -- User Option: load-warn-when-source-newer
This variable specifies whether `load' should check whether the
source is newer than the binary. If this variable is true, then
when a `.elc' file is being loaded and the corresponding `.el' is
newer, a warning message will be printed. The default is `nil',
but it is bound to `t' during the initial loadup.
- - User Option: load-warn-when-source-only
+ -- User Option: load-warn-when-source-only
This variable specifies whether `load' should warn when loading a
`.el' file instead of an `.elc'. If this variable is true, then
when `load' is called with a filename without an extension, and
`load', no warning will be printed. The default is `nil', but it
is bound to `t' during the initial loadup.
- - User Option: load-ignore-elc-files
+ -- User Option: load-ignore-elc-files
This variable specifies whether `load' should ignore `.elc' files
when a suffix is not given. This is normally used only to
bootstrap the `.elc' files when building XEmacs, when you use the

+22.1.1 Entering the Debugger on an Error
+----------------------------------------
The most important time to enter the debugger is when a Lisp error
happens. This allows you to investigate the immediate causes of the
debugger each time this happens. If you want errors to enter the
debugger, set the variable `debug-on-error' to non-`nil'.
- - User Option: debug-on-error

This variable determines whether the debugger is called when an
error is signaled and not handled. If `debug-on-error' is `t', all

errors also can invoke the debugger. *Note Processes::.

an error is signalled, regardless of whether it would be handled.

To investigate a problem that happens in the middle of a program, one
useful technique is to enter the debugger whenever a certain function is
called shortly before the problem, step quickly over the call to that
function, and then step through its caller.

This function requests FUNCTION-NAME to invoke the debugger each
time it is called. It works by inserting the form `(debug

This section describes functions and variables used internally by the
debugger.
- - Variable: debugger
+ -- Variable: debugger
The value of this variable is the function to call to invoke the
debugger. Its value must be a function of any number of arguments
(or, more typically, the name of a function). Presumably this
was called. The convention for arguments is detailed in the
description of `debug'.
- - Command: backtrace &optional stream detailed
+ -- Command: backtrace &optional stream detailed
This function prints a trace of Lisp function calls currently
active. This is the function used by `debug' to fill up the
`*Backtrace*' buffer. It is written in C, since it must have

The character `*' indicates a frame whose debug-on-exit flag is
set.
- - Variable: debug-on-next-call
+ -- Variable: debug-on-next-call
If this variable is non-`nil', it says to call the debugger before
the next `eval', `apply' or `funcall'. Entering the debugger sets
`debug-on-next-call' to `nil'.
The `d' command in the debugger works by setting this variable.
- - Function: backtrace-debug level flag

This function sets the debug-on-exit flag of the stack frame LEVEL
levels down the stack, giving it the value FLAG. If FLAG is
non-`nil', this will cause the debugger to be entered when that
This function is used only by the debugger.

This variable records the debugging status of the current
interactive command. Each time a command is called interactively,
this variable is bound to `nil'. The debugger can set this
another global variable is that the data will never carry over to a
subsequent command invocation.
- - Function: backtrace-frame frame-number

The function `backtrace-frame' is intended for use in Lisp
debuggers. It returns information about what computation is
happening in the stack frame FRAME-NUMBER levels down.

-Edebug Options
---------------
+22.4.17 Edebug Options
+----------------------
These options affect the behavior of Edebug:
- - User Option: edebug-setup-hook
+ -- User Option: edebug-setup-hook
Functions to call before Edebug is used. Each time it is set to a
new value, Edebug will call those functions once and then
`edebug-setup-hook' is reset to `nil'. You could use this to load
up Edebug specifications associated with a package you are using
but only when you also use Edebug. See *Note Instrumenting::.
- - User Option: edebug-all-defs
+ -- User Option: edebug-all-defs
If non-`nil', normal evaluation of any defining forms (e.g.
`defun' and `defmacro') will instrument them for Edebug. This
applies to `eval-defun', `eval-region', and `eval-current-buffer'.
by calling `(make-local-variable 'edebug-all-defs)' in your
`emacs-lisp-mode-hook'. See *Note Instrumenting::.
- - User Option: edebug-all-forms
+ -- User Option: edebug-all-forms
If non-`nil', normal evaluation of any forms by `eval-defun',
`eval-region', and `eval-current-buffer' will instrument them for
Edebug.
Use the command `M-x edebug-all-forms' to toggle the value of this
option. See *Note Instrumenting::.
- - User Option: edebug-save-windows
+ -- User Option: edebug-save-windows
If non-`nil', save and restore window configuration on Edebug
calls. It takes some time to do this, so if your program does not
care what happens to data about windows, you may want to set this
variable. This command is bound to `W' in source code buffers.
See *Note Edebug Display Update::.
- - User Option: edebug-save-displayed-buffer-points
+ -- User Option: edebug-save-displayed-buffer-points
If non-`nil', save and restore point in all displayed buffers.
This is necessary if you are debugging code that changes the point
of a buffer which is displayed in a non-selected window. If
so it is best to avoid it if you can. See *Note Edebug Display
Update::.
- - User Option: edebug-initial-mode
+ -- User Option: edebug-initial-mode
If this variable is non-`nil', it specifies the initial execution
mode for Edebug when it is first activated. Possible values are
`step', `next', `go', `Go-nonstop', `trace', `Trace-fast',
The default value is `step'. See *Note Edebug Execution Modes::.
- - User Option: edebug-trace
+ -- User Option: edebug-trace
Non-`nil' means display a trace of function entry and exit.
Tracing output is displayed in a buffer named `*edebug-trace*', one
function entry or exit per line, indented by the recursion level.
Also see `edebug-tracing'. See *Note Tracing::.
- - User Option: edebug-test-coverage
+ -- User Option: edebug-test-coverage
If non-`nil', Edebug tests coverage of all expressions debugged.
This is done by comparing the result of each expression with the
previous result. Coverage is considered OK if two different
and coverage information for a definition. See *Note Coverage
Testing::.
- - User Option: edebug-continue-kbd-macro
+ -- User Option: edebug-continue-kbd-macro
If non-`nil', continue defining or executing any keyboard macro
that is executing outside of Edebug. Use this with caution since
it is not debugged. See *Note Edebug Execution Modes::.
- - User Option: edebug-print-length
+ -- User Option: edebug-print-length
If non-`nil', bind `print-length' to this while printing results
in Edebug. The default value is `50'. See *Note Printing in
Edebug::.
- - User Option: edebug-print-level
+ -- User Option: edebug-print-level

+ -- Variable: minibuffer-completion-table
The value of this variable is the alist or obarray used for
completion in the minibuffer. This is the global variable that
contains what `completing-read' passes to `try-completion'. It is
used by minibuffer completion commands such as
`minibuffer-complete-word'.
- - Variable: minibuffer-completion-predicate

This variable's value is the predicate that `completing-read'
passes to `try-completion'. The variable is also used by the other
minibuffer completion functions.
- - Command: minibuffer-complete-word
+ -- Command: minibuffer-complete-word
This function completes the minibuffer contents by at most a single
word. Even if the minibuffer contents have only one completion,
`minibuffer-complete-word' does not add any characters beyond the
first character that is not a word constituent. *Note Syntax
Tables::.
- - Command: minibuffer-complete
+ -- Command: minibuffer-complete
This function completes the minibuffer contents as far as possible.
- - Command: minibuffer-complete-and-exit

confirmation of a completion before exiting the minibuffer. The
function `minibuffer-complete-and-exit' checks the value of this
variable before it exits.

+24.9 Minibuffer Miscellany
+==========================
This section describes some basic functions and variables related to
minibuffers.
- - Command: exit-minibuffer
+ -- Command: exit-minibuffer
This command exits the active minibuffer. It is normally bound to
keys in minibuffer local keymaps.
- - Command: self-insert-and-exit
+ -- Command: self-insert-and-exit
This command exits the active minibuffer after inserting the last
character typed on the keyboard (found in `last-command-char';
*note Command Loop Info::).
- - Command: previous-history-element n
+ -- Command: previous-history-element n
This command replaces the minibuffer contents with the value of the
Nth previous (older) history element.
- - Command: next-history-element n
+ -- Command: next-history-element n
This command replaces the minibuffer contents with the value of the
Nth more recent history element.
- - Command: previous-matching-history-element pattern
+ -- Command: previous-matching-history-element pattern
This command replaces the minibuffer contents with the value of the
previous (older) history element that matches PATTERN (a regular
expression).
- - Command: next-matching-history-element pattern
+ -- Command: next-matching-history-element pattern
This command replaces the minibuffer contents with the value of
the next (newer) history element that matches PATTERN (a regular
expression).
- - Function: minibuffer-prompt
+ -- Function: minibuffer-prompt
This function returns the prompt string of the currently active
minibuffer. If no minibuffer is active, it returns `nil'.
- - Function: minibuffer-prompt-width
+ -- Function: minibuffer-prompt-width
This function returns the display width of the prompt string of the
currently active minibuffer. If no minibuffer is active, it
returns 0.
- - Variable: minibuffer-setup-hook
+ -- Variable: minibuffer-setup-hook
This is a normal hook that is run whenever the minibuffer is
entered. *Note Hooks::.
- - Variable: minibuffer-exit-hook
+ -- Variable: minibuffer-exit-hook
This is a normal hook that is run whenever the minibuffer is
exited. *Note Hooks::.
- - Variable: minibuffer-help-form
+ -- Variable: minibuffer-help-form
The current value of this variable is used to rebind `help-form'
locally inside the minibuffer (*note Help Functions::).
- - Function: active-minibuffer-window
+ -- Function: active-minibuffer-window
This function returns the currently active minibuffer window, or
`nil' if none is currently active.
- - Function: minibuffer-window &optional frame
+ -- Function: minibuffer-window &optional frame
This function returns the minibuffer window used for frame FRAME.
If FRAME is `nil', that stands for the current frame. Note that
the minibuffer window used by a frame need not be part of that
frame--a frame that has no minibuffer of its own necessarily uses
some other frame's minibuffer window.
- - Function: window-minibuffer-p &optional window
+ -- Function: window-minibuffer-p &optional window
This function returns non-`nil' if WINDOW is a minibuffer window.
It is not correct to determine whether a given window is a
because there can be more than one minibuffer window if there is more
than one frame.
- - Function: minibuffer-window-active-p window
+ -- Function: minibuffer-window-active-p window
This function returns non-`nil' if WINDOW, assumed to be a
minibuffer window, is currently active.
- - Variable: minibuffer-scroll-window
+ -- Variable: minibuffer-scroll-window
If the value of this variable is non-`nil', it should be a window
object. When the function `scroll-other-window' is called in the
minibuffer, it scrolls this window.
Finally, some functions and variables deal with recursive minibuffers
(*note Recursive Editing::):
- - Function: minibuffer-depth
+ -- Function: minibuffer-depth
This function returns the current depth of activations of the
minibuffer, a nonnegative integer. If no minibuffers are active,
it returns zero.
- - User Option: enable-recursive-minibuffers
+ -- User Option: enable-recursive-minibuffers
If this variable is non-`nil', you can invoke commands (such as
`find-file') that use minibuffers even while the minibuffer window
is active. Such invocation produces a recursive editing level for

The command loop in XEmacs is a standard event loop, reading events one

To terminate the execution of a running command, type `C-g'. This
character causes "quitting" (*note Quitting::).

it invokes that definition using the function `command-execute'. If

You can also call these functions yourself.
- - Function: commandp function
+ -- Function: commandp function
Returns `t' if FUNCTION is suitable for calling interactively;
that is, if FUNCTION is a command. Otherwise, returns `nil'.
See `documentation' in *Note Accessing Documentation::, for a
realistic example of using `commandp'.
- - Function: call-interactively command &optional record-flag keys
+ -- Function: call-interactively command &optional record-flag keys
This function calls the interactively callable function COMMAND,
reading arguments according to its interactive calling
specifications. An error is signaled if COMMAND is not a function
the command is added only if it uses the minibuffer to read an
argument. *Note Command History::.
- - Function: command-execute command &optional record-flag keys

This function executes COMMAND as an editing command. The
argument COMMAND must satisfy the `commandp' predicate; i.e., it
must be an interactively callable function or a keyboard macro.
Such a definition is handled by loading the specified library and
then rechecking the definition of the symbol.
- - Command: execute-extended-command prefix-argument

+25.4 Information from the Command Loop
+======================================
The editor command loop sets several Lisp variables to keep status
records for itself and for commands that are run.
- - Variable: last-command
+ -- Variable: last-command
This variable records the name of the previous command executed by
the command loop (the one before the current command). Normally
the value is a symbol with a function definition, but this is not
the command loop, except when the command specifies a prefix
argument for the following command.
- - Variable: this-command
+ -- Variable: this-command
This variable records the name of the command now being executed by
the editor command loop. Like `last-command', it is normally a
symbol with a function definition.

This variable is set to the last input event that was read by the
command loop as part of a command. The principal use of this
variable is in `self-insert-command', which uses it to decide which

XEmacs provides primitives for creating, copying, and destroying event
objects. Many functions that return events take an event object as an
either an event object or `nil', creating the event object first in the
latter case.
- - Function: make-event &optional type plist
+ -- Function: make-event &optional type plist
This function creates a new event structure. If no arguments are
specified, the created event will be empty. To specify the event
type, use the TYPE argument. The allowed types are `empty',

;; Create a similar button-release event.
(make-event 'button-release `(button 1 modifiers (meta) x ,x y ,x))
=> #<buttonup-event meta-button1up>

;; Create a mouse-motion event.
(make-event 'motion '(x 20 y 30))

=> (channel #<x-frame "emacs" 0x8e2> x 20 y 30
modifiers nil timestamp 0)
(append '(modifiers nil)
(event-properties EVENT)))
- - Function: copy-event event1 &optional event2
+ -- Function: copy-event event1 &optional event2
This function makes a copy of the event object EVENT1. If a
second event argument EVENT2 is given, EVENT1 is copied into
EVENT2 and EVENT2 is returned. If EVENT2 is not supplied (or is
`nil') then a new event will be made, as with `make-event'.
- - Function: deallocate-event event

This function allows the given event structure to be reused. You
*MUST NOT* use this event object after calling this function with
it. You will lose. It is not necessary to call this function, as

------------------
+25.5.7 Converting Events
+------------------------
XEmacs provides some auxiliary functions for converting between events
and other ways of representing keys. These are useful when working with
ASCII strings and with keymaps.
- - Function: character-to-event key-description &optional event console
- use-console-meta-flag
+ -- Function: character-to-event key-description &optional event
+ console use-console-meta-flag
This function converts a keystroke description to an event
structure. KEY-DESCRIPTION is the specification of a key stroke,
and EVENT is the event object to fill in. This function contains
strictly inverse functions, since events contain much more
information than the ASCII character set can encode.
- - Function: event-to-character event &optional allow-extra-modifiers
+ -- Function: event-to-character event &optional allow-extra-modifiers
allow-meta allow-non-ascii
This function returns the closest ASCII approximation to EVENT.
If the event isn't a keypress, this returns `nil'.
ambiguous, as both use the high bit; <M-x> and <oslash> will be
indistinguishable.
- - Function: events-to-keys events &optional no-mice
+ -- Function: events-to-keys events &optional no-mice
Given a vector of event objects, this function returns a vector of
key descriptors, or a string (if they all fit in the ASCII range).
Optional arg NO-MICE means that button events are not allowed.

single event. These functions often make a distinction between
actions), and other events, which serve as communication between XEmacs
and the window system.
- - Function: next-event &optional event prompt

This function reads and returns a character of command input. If a
mouse click is detected, an error is signalled. The character
typed is returned as an ASCII value. This function is retained for
compatibility with Emacs 18, and is most likely the wrong thing
for you to be using: consider using `next-command-event' instead.
- - Function: enqueue-eval-event function object

This function adds an eval event to the back of the queue. The
eval event will be the next event read after all pending events.

This function is like `read-char', except that if the first

See also the variables `last-command-event' and `last-command-char'
(*Note Command Loop Info::).
- - Variable: unread-command-events
+ -- Variable: unread-command-events
This variable holds a list of events waiting to be read as command
input. The events are used in the order they appear in the list,
and removed one by one as they are used.
events should exit the search and then execute normally.
- - Variable: unread-command-event
+ -- Variable: unread-command-event
This variable holds a single event to be read as command input.
This variable is mostly obsolete now that you can use
`unread-command-events' instead; it exists only to support programs
written for versions of XEmacs prior to 19.12.
- - Function: input-pending-p
+ -- Function: input-pending-p
This function determines whether any command input is currently
available to be read. It returns immediately, with value `t' if
there is available input, `nil' otherwise. On rare occasions it
may return `t' when no input is available.
- - Variable: last-input-event

This variable is set to the last keyboard or mouse button event
received.

If the value of `last-input-event' is a keyboard event, then this
is the nearest ASCII equivalent to it. Remember that there is
_not_ a 1:1 mapping between keyboard events and ASCII characters:
This function exists for compatibility with Emacs version 18.

-Waiting for Elapsed Time or Input
-=================================
+25.7 Waiting for Elapsed Time or Input
+======================================
The wait functions are designed to wait for a certain amount of time to
pass or until there is input. For example, you may wish to pause in
two arguments to specify the time (one integer and one float value),
instead of a single argument that can be either an integer or a float.
- - Function: sit-for seconds &optional nodisplay
+ -- Function: sit-for seconds &optional nodisplay
This function performs redisplay (provided there is no pending
input from the user), then waits SECONDS seconds, or until input is
available. The result is `t' if `sit-for' waited the full time
The usual purpose of `sit-for' is to give the user time to read
text that you display.

This function simply pauses for SECONDS seconds without updating
the display. This function pays no attention to available input.
It returns `nil'.

`quit-flag' non-`nil', regardless of `inhibit-quit'.
- - Variable: inhibit-quit
+ -- Variable: inhibit-quit
This variable determines whether XEmacs should quit when
`quit-flag' is set to a value other than `nil'. If `inhibit-quit'
is non-`nil', then `quit-flag' has no special effect.

XEmacs uses two variables to store the prefix argument: `prefix-arg'
value of the prefix argument directly in the variable
`current-prefix-arg', but this is less clean.
- - Function: prefix-numeric-value raw
+ -- Function: prefix-numeric-value raw
This function returns the numeric meaning of a valid raw prefix
argument value, RAW. The argument may be a symbol, a number, or a
list. If it is `nil', the value 1 is returned; if it is `-', the
if it is a list, the CAR of that list (which should be a number) is
returned.
- - Variable: current-prefix-arg
+ -- Variable: current-prefix-arg
This variable holds the raw prefix argument for the _current_
command. Commands may examine it directly, but the usual way to
access it is with `(interactive "P")'.
- - Variable: prefix-arg
+ -- Variable: prefix-arg
The value of this variable is the raw prefix argument for the
_next_ editing command. Commands that specify prefix arguments for
the following command work by setting this variable.
`negative-argument' unless you intend to let the user enter the prefix
argument for the _next_ command.

+ -- Command: universal-argument
This command reads input and specifies a prefix argument for the
following command. Don't call this command yourself unless you
know what you are doing.
- - Command: digit-argument arg
+ -- Command: digit-argument arg
This command adds to the prefix argument for the following
command. The argument ARG is the raw prefix argument as it was
before this command; it is used to compute the updated prefix
argument. Don't call this command yourself unless you know what
you are doing.
- - Command: negative-argument arg

This command adds to the numeric argument for the next command.
The argument ARG is the raw prefix argument as it was before this

+================
Major modes specialize XEmacs for editing particular kinds of text.
-Each buffer has only one major mode at a time.
+Each buffer has only one major mode at a time. For each major mode
+there is a function to switch to that mode in the current buffer; its
+name should end in `-mode'. These functions work by setting
+buffer-local variable bindings and other data associated with the
+buffer, such as a local keymap. The effect lasts until you switch to
+another major mode in the same buffer.
The least specialized major mode is called "Fundamental mode". This
mode has no mode-specific definitions or variable settings, so each
mode except that it provides three additional commands. Its definition
is distinct from that of Text mode, but was derived from it.
+ Even if the new mode is not an obvious derivative of any other mode,
+it is convenient to use `define-derived-mode' with a `nil' parent
+argument, since it automatically enforces the most important coding
+conventions for you.

+33.1.1 Major Mode Conventions
+-----------------------------
The code for existing major modes follows various coding conventions,
including conventions for local keymap and syntax table initialization,
immediately before the mode's own hook (that is, after everything
else), or it may run them earlier.
+ * The major mode command may start by calling some other major mode
+ command (called the "parent mode") and then alter some of its
+ settings. A mode that does this is called a "derived mode". The
+ recommended way to define one is to use `define-derived-mode', but
+ this is not required. Such a mode should use `delay-mode-hooks'
+ around its entire body, including the call to the parent mode
+ command and the final call to `run-mode-hooks'. (Using
+ `define-derived-mode' does this automatically.)

from this mode to any other major mode, the mode can set a local

automatically selects a major mode for the new buffer when a file is
visited.

+ -- Command: fundamental-mode
Fundamental mode is a major mode that is not specialized for
anything in particular. Other major modes are defined in effect

This function establishes the proper major mode and local variable
bindings for the current buffer. First it calls `set-auto-mode',

mode function, so errors are caught and reported as a `File mode
specification error', followed by the original error message.

+ -- User Option: enable-local-variables
This variable controls processing of local variables lists in files

lists unconditionally; `nil' means ignore them; anything else means
ask the user what to do for each file. The default value is `t'.
- - Variable: ignored-local-variables
+ -- Variable: ignored-local-variables
This variable holds a list of variables that should not be set by
a local variables list. Any value specified for one of these
variables is ignored.
In addition to this list, any variable whose name has a non-`nil'
`risky-local-variable' property is also ignored.
- - User Option: enable-local-eval
+ -- User Option: enable-local-eval
This variable controls processing of `Eval:' in local variables

Changing this variable does not force an update of the modeline.
- - Variable: modeline-buffer-identification

This variable identifies the buffer being displayed in the window.
Its default value is `("%F: %17b")', which means that it usually

a "normal" XEmacs.
- - Variable: global-mode-string
+ -- Variable: global-mode-string
This variable holds a modeline spec that appears in the mode line
by default, just after the buffer name. The command `display-time'
sets `global-mode-string' to refer to the variable
but this is obsolete, since the variable is included directly in
the modeline.
- - Variable: mode-name
+ -- Variable: mode-name
This buffer-local variable holds the "pretty" name of the current
buffer's major mode. Each major mode should set this variable so
that the mode name will appear in the modeline.
- - Variable: minor-mode-alist
+ -- Variable: minor-mode-alist
This variable holds an association list whose elements specify how
the modeline should indicate that a minor mode is active. Each
element of the `minor-mode-alist' should be a two-element list:

enabled separately in each buffer.

This buffer-local variable contains the modeline information on

-
+
(setq c++-mode-hook c-mode-hook)
The final example shows how the appearance of the modeline can be
particular hooks. This function calls the hook functions you have
added with `add-hooks'.
- - Function: run-hooks &rest hookvar
+ -- Function: run-hooks &rest hookvar
This function takes one or more hook variable names as arguments,
and runs each hook in turn. Each HOOKVAR argument should be a
symbol that is a hook variable. These arguments are processed in
(run-hooks 'emacs-lisp-mode-hook)
- - Function: add-hook hook function &optional append local
+ -- Function: run-mode-hooks &rest hookvars
+ Like `run-hooks', but is affected by the `delay-mode-hooks' macro.
+
+ -- Macro: delay-mode-hooks body...
+ This macro executes the BODY forms but defers all calls to
+ `run-mode-hooks' within them until the end of BODY. This macro
+ enables a derived mode to arrange not to run its parent modes'
+ mode hooks until the end.
+
+ -- Function: run-hook-with-args hook &rest args
+ This function is the way to run an abnormal hook and always call
+ all of the hook functions. It calls each of the hook functions
+ one by one, passing each of them the arguments ARGS.
+
+ -- Function: run-hook-with-args-until-failure hook &rest args
+ This function is the way to run an abnormal hook until one of the
+ hook functions fails. It calls each of the hook functions,
+ passing each of them the arguments ARGS, until some hook function
+ returns `nil'. It then stops and returns `nil'. If none of the
+ hook functions return `nil', it returns a non-`nil' value.
+
+ -- Function: run-hook-with-args-until-success hook &rest args
+ This function is the way to run an abnormal hook until a hook
+ function succeeds. It calls each of the hook functions, passing
+ each of them the arguments ARGS, until some hook function returns
+ non-`nil'. Then it stops, and returns whatever was returned by
+ the last hook function that was called. If all hook functions
+ return `nil', it returns `nil' as well.
+
+ -- Function: add-hook hook function &optional append local
This function is the handy way to add function FUNCTION to hook
variable HOOK. The argument FUNCTION may be any valid Lisp
function with the proper number of arguments. For example,
buffer-local, then the value of LOCAL makes no difference--the
hook function is always global.
- - Function: remove-hook hook function &optional local
+ -- Function: remove-hook hook function &optional local
This function removes FUNCTION from the hook variable HOOK.
If LOCAL is non-`nil', that says to remove FUNCTION from the local
itself is not buffer-local, then the value of LOCAL makes no
difference.
- - Function: make-local-hook hook
+ -- Function: make-local-hook hook
This function makes the hook variable HOOK local to the current
buffer. When a hook variable is local, it can have local and
global hook functions, and `run-hooks' runs all of them.

key followed by the help character, and the help character has no
binding after that prefix. The variable's default value is
`describe-prefix-bindings'.

This section describes the functions normally used to visit files. For
historical reasons, these functions have names starting with `find-'
temporary buffer. Visiting the file is not necessary and takes longer.
*Note Reading from Files::.
- - Command: find-file filename
+ -- Command: find-file filename
This command selects a buffer visiting the file FILENAME, using an
existing buffer if there is one, and otherwise creating a new
buffer and reading the file into it. It also returns that buffer.
When `find-file' is called interactively, it prompts for FILENAME
in the minibuffer.
- - Function: find-file-noselect filename &optional nowarn
+ -- Function: find-file-noselect filename &optional nowarn
This function is the guts of all the file-visiting functions. It
finds or creates a buffer visiting the file FILENAME, and returns
it. It uses an existing buffer if there is one, and otherwise
(find-file-noselect "/etc/fstab")
=> #<buffer fstab>
- - Command: find-file-other-window filename
+ -- Command: find-file-other-window filename
This command selects a buffer visiting the file FILENAME, but does
so in a window other than the selected window. It may use another
existing window or split a window; see *Note Displaying Buffers::.
When this command is called interactively, it prompts for FILENAME.
- - Command: find-file-read-only filename
+ -- Command: find-file-read-only filename
This command selects a buffer visiting the file FILENAME, like
`find-file', but it marks the buffer as read-only. *Note Read
Only Buffers::, for related functions and variables.
When this command is called interactively, it prompts for FILENAME.
- - Command: view-file filename &optional other-window-p

This command visits FILENAME in View mode, and displays it in a
recursive edit, returning to the previous buffer when done. View
mode is a mode that allows you to skim rapidly through the file

copying the contents of the buffer into the file.
- - Command: save-buffer &optional backup-option
+ -- Command: save-buffer &optional backup-option
This function saves the contents of the current buffer in its
visited file if the buffer has been modified since it was last
visited or saved. Otherwise it does nothing.
`save-buffer' function unconditionally backs up the previous
version of the file before saving it.
- - Command: save-some-buffers &optional save-silently-p exiting
+ -- Command: save-some-buffers &optional save-silently-p exiting
This command saves some modified file-visiting buffers. Normally
it asks the user about each buffer. But if SAVE-SILENTLY-P is
non-`nil', it saves all the file-visiting buffers without querying
`save-buffers-kill-emacs' function passes a non-`nil' value for
this argument.
- - Variable: buffer-offer-save
+ -- Variable: buffer-offer-save
When this variable is non-`nil' in a buffer, XEmacs offers to save
the buffer on exit even if the buffer is not visiting a file. The
variable is automatically local in all buffers. Normally, Mail
mode (used for editing outgoing mail) sets this to `t'.
- - Command: write-file filename
+ -- Command: write-file filename
This function writes the current buffer into file FILENAME, makes
the buffer visit that file, and marks it not modified. Then it
renames the buffer based on FILENAME, appending a string like `<2>'
if necessary to make a unique buffer name. It does most of this
work by calling `set-visited-file-name' and `save-buffer'.
- - Variable: write-file-hooks

The value of this variable is a list of functions to be called
before writing out a buffer to its visited file. If one of them

This works just like `write-file-hooks', but it is intended for
hooks that pertain to the contents of the file, as opposed to
hooks that pertain to where the file came from. Such hooks are
variable. Switching to a new major mode always resets this
variable.
- - Variable: after-save-hook
+ -- Variable: after-save-hook
This normal hook runs after a buffer has been saved in its visited
file.
- - Variable: file-precious-flag
+ -- Variable: file-precious-flag
If this variable is non-`nil', then `save-buffer' protects against
I/O errors while saving by writing the new file to a temporary
name instead of the name it is supposed to have, and then renaming
Some modes set this variable non-`nil' locally in particular
buffers.
- - User Option: require-final-newline
+ -- User Option: require-final-newline
This variable determines whether files may be written out that do
_not_ end with a newline. If the value of the variable is `t',
then `save-buffer' silently adds a newline at the end of the file

You can write the contents of a buffer, or part of a buffer, directly
to a file on disk using the `append-to-file' and `write-region'
functions. Don't use these functions to write to files that are being
visited; that could cause confusion in the mechanisms for visiting.

This function appends the contents of the region delimited by
START and END in the current buffer to the end of file FILENAME.
If that file does not exist, it is created. If that file exists
An error is signaled if FILENAME specifies a nonwritable file, or
a nonexistent file in a directory where files cannot be created.

Most XEmacs Lisp file-manipulation functions get errors when used on
files that are directories. For example, you cannot delete a directory
with `delete-file'. These special functions exist to create and delete
directories.
- - Command: make-directory dirname &optional parents

always happens.)

proper behavior in the case of multiple handlers, and for operations
that have two file names that may each have handlers.

The operation for which certain handlers are presently inhibited.
- - Function: find-file-name-handler filename &optional operation
+ -- Function: find-file-name-handler filename &optional operation
This function returns the handler function for file name FILENAME,
or `nil' if there is none. The argument OPERATION should be the
operation to be performed on the file--the value you will pass to
the handler as its first argument when you call it. The operation
is needed for comparison with `inhibit-file-name-operation'.
- - Function: file-local-copy filename
+ -- Function: file-local-copy filename
This function copies file FILENAME to an ordinary non-magic file,
if it isn't one already.
If FILENAME is an ordinary file name, not magic, then this function
does nothing and returns `nil'.
- - Function: unhandled-file-name-directory filename
+ -- Function: unhandled-file-name-directory filename
This function returns the name of a directory that is not magic.
It uses the directory part of FILENAME if that is not magic.
Otherwise, it asks the handler what to do.

+================
XEmacs periodically saves all files that you are visiting; this is
called "auto-saving". Auto-saving prevents you from losing more than a
users. Here we describe the functions used to implement auto-saving
and the variables that control them.
- - Variable: buffer-auto-save-file-name
+ -- Variable: buffer-auto-save-file-name
This buffer-local variable is the name of the file used for
auto-saving the current buffer. It is `nil' if the buffer should
not be auto-saved.
buffer-auto-save-file-name
=> "/xcssun/users/rms/lewis/#files.texi#"
- - Command: auto-save-mode arg
+ -- Command: auto-save-mode arg
When used interactively without an argument, this command is a
toggle switch: it turns on auto-saving of the current buffer if it
is off, and vice-versa. With an argument ARG, the command turns
auto-saving on if the value of ARG is `t', a nonempty list, or a
positive integer. Otherwise, it turns auto-saving off.
- - Function: auto-save-file-name-p filename
+ -- Function: auto-save-file-name-p filename
This function returns a non-`nil' value if FILENAME is a string
that could be the name of an auto-save file. It works based on
knowledge of the naming convention for auto-save files: a name that
it, be sure to redefine the function `make-auto-save-file-name'
correspondingly.
- - Function: make-auto-save-file-name &optional filename
+ -- Function: make-auto-save-file-name &optional filename
This function returns the file name to use for auto-saving the
current buffer. This is just the file name with hash marks (`#')
appended and prepended to it. This function does not look at the
customize the naming convention for auto-save files. Be sure to
change `auto-save-file-name-p' in a corresponding way.
- - Variable: auto-save-visited-file-name
+ -- Variable: auto-save-visited-file-name
If this variable is non-`nil', XEmacs auto-saves buffers in the
files they are visiting. That is, the auto-save is done in the
same file that you are editing. Normally, this variable is `nil',
buffer. If auto-save mode is already enabled, auto-saves continue
to go in the same file name until `auto-save-mode' is called again.
- - Function: recent-auto-save-p
+ -- Function: recent-auto-save-p
This function returns `t' if the current buffer has been
auto-saved since the last time it was read in or saved.
- - Function: set-buffer-auto-saved
+ -- Function: set-buffer-auto-saved
This function marks the current buffer as auto-saved. The buffer
will not be auto-saved again until the buffer text is changed
again. The function returns `nil'.
- - User Option: auto-save-interval
+ -- User Option: auto-save-interval
The value of this variable is the number of characters that XEmacs
reads from the keyboard between auto-saves. Each time this many
more characters are read, auto-saving is done for all buffers in
which it is enabled.
- - User Option: auto-save-timeout
+ -- User Option: auto-save-timeout
The value of this variable is the number of seconds of idle time
that should cause auto-saving. Each time the user pauses for this
long, XEmacs auto-saves any buffers that need it. (Actually, the
specified timeout is multiplied by a factor depending on the size
of the current buffer.)
- - Variable: auto-save-hook
+ -- Variable: auto-save-hook
This normal hook is run whenever an auto-save is about to happen.
- - User Option: auto-save-default
+ -- User Option: auto-save-default
If this variable is non-`nil', buffers that are visiting files
have auto-saving enabled by default. Otherwise, they do not.
- - Command: do-auto-save &optional no-message current-only
+ -- Command: do-auto-save &optional no-message current-only
This function auto-saves all buffers that need to be auto-saved.
It saves all buffers for which auto-saving is enabled and that
have been changed since the previous auto-save.
If CURRENT-ONLY is non-`nil', only the current buffer is
auto-saved.
- - Function: delete-auto-save-file-if-necessary
+ -- Function: delete-auto-save-file-if-necessary
This function deletes the current buffer's auto-save file if
`delete-auto-save-files' is non-`nil'. It is called every time a
buffer is saved.
- - Variable: delete-auto-save-files
+ -- Variable: delete-auto-save-files
This variable is used by the function
`delete-auto-save-file-if-necessary'. If it is non-`nil', Emacs
deletes auto-save files when a true save is done (in the visited
file). This saves disk space and unclutters your directory.
- - Function: rename-auto-save-file
+ -- Function: rename-auto-save-file
This function adjusts the current buffer's auto-save file name if
the visited file name has changed. It also renames an existing
auto-save file. If the visited file name has not changed, this
function does nothing.
- - Variable: buffer-saved-size
+ -- Variable: buffer-saved-size
The value of this buffer-local variable is the length of the
current buffer as of the last time it was read in, saved, or
auto-saved. This is used to detect a substantial decrease in
auto-saving. Turning auto-save mode off or on also alters this
variable.
- - Variable: auto-save-list-file-name
+ -- Variable: auto-save-list-file-name
This variable (if non-`nil') specifies a file for recording the
names of all the auto-save files. Each time XEmacs does
auto-saving, it writes two lines into this file for each buffer

function receives two arguments: first the file name to use;
second, `t' if the user has asked to read the auto-save file.
- - Variable: before-revert-hook

This function returns `t' if the buffer BUFFER has been modified
since it was last read in from a file or saved, or `nil'
otherwise. If BUFFER is not supplied, the current buffer is
tested.
- - Function: set-buffer-modified-p flag &optional buffer

This function marks BUFFER as modified if FLAG is non-`nil', or as
unmodified if the flag is `nil'. BUFFER defaults to the current
buffer.

marked as modified.) Don't use this function in programs, since it
prints a message in the echo area; use `set-buffer-modified-p'
(above) instead.

This function compares what BUFFER has recorded for the
modification time of its visited file against the actual

This hook is called each time a frame is created. The functions
are called with one argument, the newly-created frame.

This hook is called each time a frame is deleted. The functions
are called with one argument, the about-to-be-deleted frame.
- - Variable: select-frame-hook
+ -- Variable: select-frame-hook
This is a normal hook that is run just after a frame is selected.
The function `default-select-frame-hook', which implements
auto-raising (*note Raising and Lowering::), is normally attached
the next time that XEmacs is waiting for an event, and even then,
the window manager may refuse the focus-change request.
- - Variable: deselect-frame-hook
+ -- Variable: deselect-frame-hook
This is a normal hook that is run just before a frame is deselected
(and another frame is selected). The function
`default-deselect-frame-hook', which implements auto-lowering
(*note Raising and Lowering::), is normally attached to this hook.
- - Variable: map-frame-hook
+ -- Variable: map-frame-hook
This hook is called each time a frame is mapped (i.e. made
visible). The functions are called with one argument, the newly
mapped frame.
- - Variable: unmap-frame-hook
+ -- Variable: unmap-frame-hook
This hook is called each time a frame is unmapped (i.e. made
invisible or iconified). The functions are called with one
argument, the newly unmapped frame.

-Most buffers have an "undo list", which records all changes made to the
-buffer's text so that they can be undone. (The buffers that don't have
-one are usually special-purpose buffers for which XEmacs assumes that
-undoing is not useful.) All the primitives that modify the text in the
-buffer automatically add elements to the front of the undo list, which
-is in the variable `buffer-undo-list'.
-
- - Variable: buffer-undo-list
- This variable's value is the undo list of the current buffer. A
- value of `t' disables the recording of undo information.
-
- Here are the kinds of elements an undo list can have:
-
-`INTEGER'
- This kind of element records a previous value of point. Ordinary
- cursor motion does not get any sort of undo record, but deletion
- commands use these entries to record where point was before the
- command.
-
-`(START . END)'
- This kind of element indicates how to delete text that was
- inserted. Upon insertion, the text occupied the range START-END
- in the buffer.
-
-`(TEXT . POSITION)'
- This kind of element indicates how to reinsert text that was
- deleted. The deleted text itself is the string TEXT. The place to
- reinsert it is `(abs POSITION)'.
-
-`(t HIGH . LOW)'
- This kind of element indicates that an unmodified buffer became
- modified. The elements HIGH and LOW are two integers, each
- recording 16 bits of the visited file's modification time as of
- when it was previously visited or saved. `primitive-undo' uses
- those values to determine whether to mark the buffer as unmodified
- once again; it does so only if the file's modification time
- matches those numbers.
-
-`(nil PROPERTY VALUE START . END)'
- This kind of element records a change in a text property. Here's
- how you might undo the change:
-
- (put-text-property START END PROPERTY VALUE)
-
-`POSITION'
- This element indicates where point was at an earlier time.
- Undoing this element sets point to POSITION. Deletion normally
- creates an element of this kind as well as a reinsertion element.
-
-`nil'
- This element is a boundary. The elements between two boundaries
- are called a "change group"; normally, each change group
- corresponds to one keyboard command, and undo commands normally
- undo an entire group as a unit.
-
- - Function: undo-boundary
- This function places a boundary element in the undo list. The undo
- command stops at such a boundary, and successive undo commands undo
- to earlier and earlier boundaries. This function returns `nil'.
-
- The editor command loop automatically creates an undo boundary
- before each key sequence is executed. Thus, each undo normally
- undoes the effects of one command. Self-inserting input
- characters are an exception. The command loop makes a boundary
- for the first such character; the next 19 consecutive
- self-inserting input characters do not make boundaries, and then
- the 20th does, and so on as long as self-inserting characters
- continue.
-
- All buffer modifications add a boundary whenever the previous
- undoable change was made in some other buffer. This way, a
- command that modifies several buffers makes a boundary in each
- buffer it changes.
-
- Calling this function explicitly is useful for splitting the
- effects of a command into more than one unit. For example,
- `query-replace' calls `undo-boundary' after each replacement, so
- that the user can undo individual replacements one by one.
-
- - Function: primitive-undo count list
- This is the basic function for undoing elements of an undo list.
- It undoes the first COUNT elements of LIST, returning the rest of
- LIST. You could write this function in Lisp, but it is convenient
- to have it in C.
-
- `primitive-undo' adds elements to the buffer's undo list when it
- changes the buffer. Undo commands avoid confusion by saving the
- undo list value at the beginning of a sequence of undo operations.
- Then the undo operations use and update the saved value. The new
- elements added by undoing are not part of this saved value, so
- they don't interfere with continuing to undo.

- - User Option: fill-prefix
+ -- User Option: fill-prefix
This variable specifies a string of text that appears at the
beginning of normal text lines and should be disregarded when
filling them. Any line that fails to start with the fill prefix
The fill prefix follows the left margin whitespace, if any.
- - User Option: fill-column
+ -- User Option: fill-column
This buffer-local variable specifies the maximum width of filled
lines. Its value should be an integer, which is a number of
columns. All the filling, justification and centering commands
the line will be too long for people to read comfortably, and this
can make the text seem clumsy.
- - Variable: default-fill-column
+ -- Variable: default-fill-column
The value of this variable is the default value for `fill-column'
in buffers that do not override it. This is the same as
`(default-value 'fill-column)'.
The default value for `default-fill-column' is 70.
- - Command: set-left-margin from to margin
+ -- Command: set-left-margin from to margin
This sets the `left-margin' property on the text from FROM to TO
to the value MARGIN. If Auto Fill mode is enabled, this command
also refills the region to fit the new margin.
- - Command: set-right-margin from to margin
+ -- Command: set-right-margin from to margin
This sets the `right-margin' property on the text from FROM to TO
to the value MARGIN. If Auto Fill mode is enabled, this command
also refills the region to fit the new margin.
- - Function: current-left-margin
+ -- Function: current-left-margin
This function returns the proper left margin value to use for
filling the text around point. The value is the sum of the
`left-margin' property of the character at the start of the
current line (or zero if none), and the value of the variable
`left-margin'.
- - Function: current-fill-column
+ -- Function: current-fill-column
This function returns the proper fill column value to use for
filling the text around point. The value is the value of the
`fill-column' variable, minus the value of the `right-margin'
property of the character after point.
- - Command: move-to-left-margin &optional n force
+ -- Command: move-to-left-margin &optional n force
This function moves point to the left margin of the current line.
The column moved to is determined by calling the function
`current-left-margin'. If the argument N is non-`nil',
If FORCE is non-`nil', that says to fix the line's indentation if
that doesn't match the left margin value.
- - Function: delete-to-left-margin &optional from to
+ -- Function: delete-to-left-margin &optional from to
This function removes left margin indentation from the text
between FROM and TO. The amount of indentation to delete is
determined by calling `current-left-margin'. In no case does this
The arguments FROM and TO are optional; the default is the whole
buffer.
- - Function: indent-to-left-margin
+ -- Function: indent-to-left-margin
This is the default `indent-line-function', used in Fundamental
mode, Text mode, etc. Its effect is to adjust the indentation at
the beginning of the current line to the value specified by the
variable `left-margin'. This may involve either inserting or
deleting whitespace.
- - Variable: left-margin
+ -- Variable: left-margin
This variable specifies the base left margin column. In
Fundamental mode, <LFD> indents to this column. This variable
automatically becomes buffer-local when set in any fashion.

+==================
Auto Fill mode is a minor mode that fills lines automatically as text
is inserted. This section describes the hook used by Auto Fill mode.
Auto Fill mode also enables the functions that change the margins and
justification style to refill portions of the text. *Note Margins::.
- - Variable: auto-fill-function
+ -- Variable: auto-fill-function
The value of this variable should be a function (of no arguments)
to be called after self-inserting a space or a newline. It may be
`nil', in which case nothing special is done in that case.

This command alphabetically sorts lines in the region between
START and END. If REVERSE is non-`nil', the sort is in reverse
order.
- - Command: sort-paragraphs reverse start end

This command alphabetically sorts paragraphs in the region between
START and END. If REVERSE is non-`nil', the sort is in reverse
order.
- - Command: sort-pages reverse start end

This command alphabetically sorts pages in the region between
START and END. If REVERSE is non-`nil', the sort is in reverse
order.
- - Command: sort-fields field start end
+ -- Command: sort-fields field start end
This command sorts lines in the region between START and END,
comparing them alphabetically by the FIELDth field of each line.
Fields are separated by whitespace and numbered starting from 1.
If FIELD is negative, sorting is by the -FIELDth field from the
end of the line. This command is useful for sorting tables.
- - Command: sort-numeric-fields field start end
+ -- Command: sort-numeric-fields field start end
This command sorts lines in the region between START and END,
comparing them numerically by the FIELDth field of each line. The
specified field must contain a number in each line of the region.
If FIELD is negative, sorting is by the -FIELDth field from the
end of the line. This command is useful for sorting tables.
- - Command: sort-columns reverse &optional start end
+ -- Command: sort-columns reverse &optional start end
This command sorts the lines in the region between START and END,
comparing them alphabetically by a certain range of columns. The
column positions of START and END bound the range of columns to

-Indentation Primitives
-----------------------
+43.16.1 Indentation Primitives
+------------------------------
This section describes the primitive functions used to count and insert
indentation. The functions in the following sections use these
primitives.
- - Function: current-indentation &optional buffer
+ -- Function: current-indentation &optional buffer
This function returns the indentation of the current line, which is
the horizontal position of the first nonblank character. If the
contents are entirely blank, then this is the horizontal position
of the end of the line.
- - Command: indent-to column &optional minimum buffer
+ -- Command: indent-to column &optional minimum buffer
This function indents from point with tabs and spaces until COLUMN
is reached. If MINIMUM is specified and non-`nil', then at least
that many spaces are inserted even if this requires going beyond
indentation ends. If BUFFER is `nil', the current buffer is
assumed.
- - User Option: indent-tabs-mode

This variable's value is the function to be used by <TAB> (and
various commands) to indent the current line. The command
`indent-according-to-mode' does no more than call this function.
for indentation, the value is `indent-to-left-margin' (which is the
default value).
- - Command: indent-according-to-mode

This command calls the function in `indent-line-function' to
indent the current line in a way appropriate for the current major
mode.
- - Command: indent-for-tab-command &optional prefix-arg
+ -- Command: indent-for-tab-command &optional prefix-arg
This command calls the function in `indent-line-function' to indent
the current line; except that if that function is
`indent-to-left-margin', it calls `insert-tab' instead. (That is
a trivial command that inserts a tab character.)
- - Command: newline-and-indent
+ -- Command: newline-and-indent
This function inserts a newline, then indents the new line (the one
following the newline just inserted) according to the major mode.
`newline-and-indent' indents to the column specified by
`left-margin'.
- - Command: reindent-then-newline-and-indent
+ -- Command: reindent-then-newline-and-indent
This command reindents the current line, inserts a newline at

+43.18.6 Fields
+--------------
+
+Emacs supplies a notion of a _text field_, which is a region of text
+where every character has the same value of the `field' property. It
+is used to identify regions of a buffer used for communicating with an
+external process, for example. XEmacs supplies a compatible interface.
+In XEmacs, the `field' property can be set as either an extent
+property or a text property, mirroring the Emacs capability of using
+either overlays or text properties.
+
+ The field manipulating functions take a buffer position as the
+field-identifying argument, defaulting to point. This really means the
+field containing that buffer position. Consecutive buffer positions
+with no `field' property are considered an "empty" field. There is
+some ambiguity when a specified buffer position falls at the very
+beginning or the very end of a field: does it belong to the preceding or
+the following field? The answer depends on the openness or closedness
+of the corresponding extents (*note Extent Endpoints::). A buffer
+position corresponds to the field whose property would be inherited by a
+character inserted at that position. If the buffer position is between
+an end-open and a start-open extent, then it corresponds to an empty
+field at that position, since an inserted character will belong to
+neither extent.
+
+ -- Variable: inhibit-field-text-motion
+ This variable controls whether the text motion commands notice
+ fields or not. When it is nil (the default), commands such as
+ beginning-of-line will try to move only within fields.
+
+ -- Function: make-field value from to &optional buffer
+ There is no Emacs counterpart to this function. The default open
+ and closedness of extents in XEmacs is opposite to the default for
+ Emacs overlays. Hence, fields based on extents in XEmacs behave
+ differently from the equivalent fields based on overlays in Emacs.
+ This function creates a field with value VALUE over the region
+ FROM to TO in BUFFER, which defaults to the current buffer, with
+ the default Emacs open and closedness.
+
+ -- Function: find-field &optional pos merge-at-boundary beg-limit
+ end-limit
+ There is no (Lisp-visible) Emacs counterpart to this function. It
+ is the workhorse for the other functions. It returns a dotted pair
+ `(start . stop)' holding the endpoints of the field matching a
+ specification. If POS is non-`nil', it specifies a buffer
+ position whose enclosing field should be found; otherwise, the
+ value of point is used.
+
+ If MERGE-AT-BOUNDARY is non-`nil', then two changes are made to
+ the search algorithm. First, if POS is at the very first position
+ of a field, then the beginning of the previous field is returned
+ instead of the beginning of POS's field. Second, if the value of
+ the `field' property at POS is the symbol `boundary', then the
+ beginning of the field before the boundary field and the end of
+ the field after the boundary field are returned.
+
+ If BEG-LIMIT is a buffer position, and the start position that
+ would be returned is less than BEG-LIMIT, then BEG-LIMIT is
+ returned instead. Likewise, if END-LIMIT is a buffer position,
+ and the stop position that would be returned is greater than

-Table of Syntax Classes
------------------------
+45.2.1 Table of Syntax Classes
+------------------------------
Here is a table of syntax classes, the characters that stand for them,
their meanings, and examples of their use.
- - Syntax class: whitespace character
+ -- Syntax class: whitespace character
"Whitespace characters" (designated with `-') separate symbols and
words from each other. Typically, whitespace characters have no
other syntactic significance, and multiple whitespace characters

Emacs.)
- - Syntax class: word constituent
+ -- Syntax class: word constituent
"Word constituents" (designated with `w') are parts of normal
English words and are typically used in variable and command names
in programs. All upper- and lower-case letters, and the digits,
are typically word constituents.
- - Syntax class: symbol constituent
+ -- Syntax class: symbol constituent
"Symbol constituents" (designated with `_') are the extra
characters that are used in variable and command names along with
word constituents. For example, the symbol constituents class is
non-word-constituent character that is valid in symbols is
underscore (`_').
- - Syntax class: punctuation character
+ -- Syntax class: punctuation character
"Punctuation characters" (`.') are those characters that are used
as punctuation in English, or are used in some way in a programming
language to separate symbols from one another. Most programming
this class since the few characters that are not symbol or word
constituents all have other uses.
- - Syntax class: open parenthesis character
- - Syntax class: close parenthesis character
+ -- Syntax class: open parenthesis character
+ -- Syntax class: close parenthesis character
Open and close "parenthesis characters" are characters used in
dissimilar pairs to surround sentences or expressions. Such a
grouping is begun with an open parenthesis character and
`[]', and `{}'. In XEmacs Lisp, the delimiters for lists and
vectors (`()' and `[]') are classified as parenthesis characters.
- - Syntax class: string quote
+ -- Syntax class: string quote
"String quote characters" (designated with `"') are used in many
languages, including Lisp and C, to delimit string constants. The
same string quote character appears at the beginning and the end
English, we do not want them to turn off the usual syntactic
properties of other characters in the quotation.
- - Syntax class: escape

An "escape character" (designated with `\') starts an escape
sequence such as is used in C string and character constants. The
character `\' belongs to this class in both C and Lisp. (In C, it
Characters in this class count as part of words if
`words-include-escapes' is non-`nil'. *Note Word Motion::.

A "character quote character" (designated with `/') quotes the
following character so that it loses its normal syntactic meaning.
This differs from an escape character in that only the character
This class is used for backslash in TeX mode.
- - Syntax class: paired delimiter
+ -- Syntax class: paired delimiter
"Paired delimiter characters" (designated with `$') are like
string quote characters except that the syntactic properties of the
characters between the delimiters are not suppressed. Only TeX
mode uses a paired delimiter presently--the `$' that both enters
and leaves math mode.
- - Syntax class: expression prefix
+ -- Syntax class: expression prefix
An "expression prefix operator" (designated with `'') is used for
syntactic operators that are part of an expression if they appear
next to one. These characters in Lisp include the apostrophe, `''
(used for quoting), the comma, `,' (used in macros), and `#' (used
in the read syntax for certain data types).
- - Syntax class: comment starter
- - Syntax class: comment ender
+ -- Syntax class: comment starter
+ -- Syntax class: comment ender
The "comment starter" and "comment ender" characters are used in
various languages to delimit comments. These classes are
designated with `<' and `>', respectively.
English text has no comment characters. In Lisp, the semicolon
(`;') starts a comment and a newline or formfeed ends one.
- - Syntax class: inherit
+ -- Syntax class: inherit
This syntax class does not specify a syntax. It says to look in
the standard syntax table to find the syntax of this character.
The designator for this syntax code is `@'.

This function creates a new syntax table. Character codes 0
through 31 and 128 through 255 are set up to inherit from the
standard syntax table. The other character codes are set up by
Most major mode syntax tables are created in this way.
- - Function: copy-syntax-table &optional syntax-table
+ -- Function: copy-syntax-table &optional syntax-table
This function constructs a copy of SYNTAX-TABLE and returns it.
If SYNTAX-TABLE is not supplied (or is `nil'), it returns a copy
of the current syntax table. Otherwise, an error is signaled if
SYNTAX-TABLE is not a syntax table.
- - Command: modify-syntax-entry char-range syntax-descriptor &optional
+ -- Command: modify-syntax-entry char-range syntax-descriptor &optional
syntax-table
This function sets the syntax entry for CHAR-RANGE according to
SYNTAX-DESCRIPTOR. CHAR-RANGE is either a single character or a

;; and the second character of an end-comment sequence.
(modify-syntax-entry ?/ ". 14")
=> nil
- - Function: char-syntax character &optional syntax-table
+ -- Function: char-syntax character &optional syntax-table
This function returns the syntax class of CHARACTER, represented
by its mnemonic designator character. This _only_ returns the

This function is most often used to compute indentation for
languages that have nested parentheses.
- - Function: scan-lists from count depth &optional buffer noerror
+ -- Function: scan-lists from count depth &optional buffer noerror
This function scans forward COUNT balanced parenthetical groupings
from character number FROM. It returns the character position
where the scan stops.
If optional arg NOERROR is non-`nil', `scan-lists' will return
`nil' instead of signalling an error.
- - Function: scan-sexps from count &optional buffer noerror
+ -- Function: scan-sexps from count &optional buffer noerror
This function scans forward COUNT sexps from character position
FROM. It returns the character position where the scan stops.
If optional arg NOERROR is non-`nil', `scan-sexps' will return nil
instead of signalling an error.
- - Variable: parse-sexp-ignore-comments

This function undefines all the abbrevs in abbrev table TABLE,
leaving it empty. The function returns `nil'.
- - Function: define-abbrev-table table-name definitions
+ -- Function: define-abbrev-table table-name definitions
This function defines TABLE-NAME (a symbol) as an abbrev table
name, i.e., as a variable whose value is an abbrev table. It
defines abbrevs in the table according to DEFINITIONS, a list of
elements of the form `(ABBREVNAME EXPANSION HOOK USECOUNT)'. The
value is always `nil'.
- - Variable: abbrev-table-name-list
+ -- Variable: abbrev-table-name-list
This is a list of symbols whose values are abbrev tables.
`define-abbrev-table' adds the new abbrev table name to this list.
- - Function: insert-abbrev-table-description name &optional human

`define-abbrev' is the low-level basic function, while `add-abbrev' is
used by commands that ask for information from the user.
- - Function: add-abbrev table type arg
+ -- Function: add-abbrev table type arg
This function adds an abbreviation to abbrev table TABLE based on
information from the user. The argument TYPE is a string
describing in English the kind of abbrev this will be (typically,
abbrev, or `nil' if the user declines to confirm redefining an
existing abbrev.
- - Function: define-abbrev table name &optional expansion hook count

Abbrevs are usually expanded by commands for interactive use, including
`self-insert-command'. This section describes the subroutines used in
writing such functions, as well as the variables they use for
communication.
- - Function: abbrev-symbol abbrev &optional table
+ -- Function: abbrev-symbol abbrev &optional table
This function returns the symbol representing the abbrev named
ABBREV. The value returned is `nil' if that abbrev is not
defined. The optional second argument TABLE is the abbrev table
the current buffer's local abbrev table, and second the global
abbrev table.
- - Function: abbrev-expansion abbrev &optional table
+ -- Function: abbrev-expansion abbrev &optional table
This function returns the string that ABBREV would expand into (as
defined by the abbrev tables used for the current buffer). The
optional argument TABLE specifies the abbrev table to use, as in
`abbrev-symbol'.
- - Command: expand-abbrev
+ -- Command: expand-abbrev
This command expands the abbrev before point, if any. If point
does not follow an abbrev, this command does nothing. The command
returns `t' if it did expansion, `nil' otherwise.
- - Command: abbrev-prefix-mark &optional arg
+ -- Command: abbrev-prefix-mark &optional arg
Mark current point as the beginning of an abbrev. The next call to
`expand-abbrev' will use the text from here to point (where it is
then) as the abbrev to expand, rather than using the previous word
as usual.
- - User Option: abbrev-all-caps
+ -- User Option: abbrev-all-caps
When this is set non-`nil', an abbrev entered entirely in upper
case is expanded using all upper case. Otherwise, an abbrev
entered entirely in upper case is expanded by capitalizing each
word of the expansion.
- - Variable: abbrev-start-location
+ -- Variable: abbrev-start-location
This is the buffer position for `expand-abbrev' to use as the start
of the next abbrev to be expanded. (`nil' means use the word
before point instead.) `abbrev-start-location' is set to `nil'
each time `expand-abbrev' is called. This variable is also set by
`abbrev-prefix-mark'.
- - Variable: abbrev-start-location-buffer
+ -- Variable: abbrev-start-location-buffer
The value of this variable is the buffer for which
`abbrev-start-location' has been set. Trying to expand an abbrev
in any other buffer clears `abbrev-start-location'. This variable
is set by `abbrev-prefix-mark'.
- - Variable: last-abbrev
+ -- Variable: last-abbrev
This is the `abbrev-symbol' of the last abbrev expanded. This
information is left by `expand-abbrev' for the sake of the
`unexpand-abbrev' command.
- - Variable: last-abbrev-location
+ -- Variable: last-abbrev-location
This is the location of the last abbrev expanded. This contains
information left by `expand-abbrev' for the sake of the
`unexpand-abbrev' command.

+ -- Variable: last-abbrev-text
This is the exact expansion text of the last abbrev expanded,
after case conversion (if any). Its value is `nil' if the abbrev
has already been unexpanded. This contains information left by
`expand-abbrev' for the sake of the `unexpand-abbrev' command.

the following function may be more convenient than `map-extents'.
- - Function: mapcar-extents function &optional predicate
+ -- Function: mapcar-extents function &optional predicate
buffer-or-string from to flags property value
This function applies FUNCTION to all extents which overlap a
region in BUFFER-OR-STRING. The region is delimited by FROM and
VALUE may also be used to control the extents passed to PREDICATE
or FUNCTION, and have the same meaning as in `map-extents'.
- - Function: map-extent-children function &optional object from to
+ -- Function: map-extent-children function &optional object from to
maparg flags property value
This function is similar to `map-extents', but differs in that:

-Face Properties
----------------
-
-You can examine and modify the properties of an existing face with the
-following functions.
-
- The following symbols have predefined meanings:
-
-`foreground'
- The foreground color of the face.
-
-`background'
- The background color of the face.
-
-`font'
- The font used to display text covered by this face.
-
-`display-table'
- The display table of the face.
-
-`background-pixmap'
- The pixmap displayed in the background of the face. Only used by
- faces on X devices.
-
-`underline'
- Underline all text covered by this face.
-
-`highlight'
- Highlight all text covered by this face. Only used by faces on TTY
- devices.
-
-`dim'
- Dim all text covered by this face. Only used by faces on TTY
- devices.
-
-`blinking'
- Blink all text covered by this face. Only used by faces on TTY
- devices.
-
-`reverse'
- Reverse the foreground and background colors. Only used by faces
- on TTY devices.
-
-`doc-string'
- Description of what the face's normal use is. NOTE: This is not a
- specifier, unlike all the other built-in properties, and cannot
- contain locale-specific values.
-
- - Function: set-face-property face property value &optional locale
- tag-set how-to-add
- This function changes a property of a FACE.
-
- For built-in properties, the actual value of the property is a
- specifier and you cannot change this; but you can change the
- specifications within the specifier, and that is what this
- function will do. For user-defined properties, you can use this
- function to either change the actual value of the property or, if
- this value is a specifier, change the specifications within it.
-
- If PROPERTY is a built-in property, the specifications to be added
- to this property can be supplied in many different ways:
-
- If VALUE is a simple instantiator (e.g. a string naming a
- font or color) or a list of instantiators, then the
- instantiator(s) will be added as a specification of the
- property for the given LOCALE (which defaults to `global' if
- omitted).
-
- If VALUE is a list of specifications (each of which is a cons
- of a locale and a list of instantiators), then LOCALE must be
- `nil' (it does not make sense to explicitly specify a locale
- in this case), and specifications will be added as given.
-
- If VALUE is a specifier (as would be returned by
- `face-property' if no LOCALE argument is given), then some or
- all of the specifications in the specifier will be added to
- the property. In this case, the function is really
- equivalent to `copy-specifier' and LOCALE has the same
- semantics (if it is a particular locale, the specification
- for the locale will be copied; if a locale type,
- specifications for all locales of that type will be copied;
- if `nil' or `all', then all specifications will be copied).
-
- HOW-TO-ADD should be either `nil' or one of the symbols `prepend',
- `append', `remove-tag-set-prepend', `remove-tag-set-append',
- `remove-locale', `remove-locale-type', or `remove-all'. See
- `copy-specifier' and `add-spec-to-specifier' for a description of
- what each of these means. Most of the time, you do not need to
- worry about this argument; the default behavior usually is fine.
-
- In general, it is OK to pass an instance object (e.g. as returned
- by `face-property-instance') as an instantiator in place of an
- actual instantiator. In such a case, the instantiator used to
- create that instance object will be used (for example, if you set
- a font-instance object as the value of the `font' property, then
- the font name used to create that object will be used instead).
- If some cases, however, doing this conversion does not make sense,
- and this will be noted in the documentation for particular types
- of instance objects.
-
- If PROPERTY is not a built-in property, then this function will
- simply set its value if LOCALE is `nil'. However, if LOCALE is
- given, then this function will attempt to add VALUE as the
- instantiator for the given LOCALE, using `add-spec-to-specifier'.
- If the value of the property is not a specifier, it will
- automatically be converted into a `generic' specifier.
-
- - Function: remove-face-property face property &optional locale
- tag-set exact-p
- This function removes a property of a FACE.
-
- For built-in properties, this is analogous to `remove-specifier'.
- For more information, *Note Other Specification Functions::.
-
- When PROPERTY is not a built-in property, this function will just
- remove its value if LOCALE is `nil' or `all'. However, if LOCALE
- is other than that, this function will attempt to remove VALUE as
- the instantiator for the given LOCALE with `remove-specifier'. If
- the value of the property is not a specifier, it will be converted
- into a `generic' specifier automatically.
-
- - Function: face-property face property &optional locale tag-set
- exact-p
- This function returns FACE's value of the given PROPERTY.
-
- If LOCALE is omitted, the FACE's actual value for PROPERTY will be
- returned. For built-in properties, this will be a specifier
- object of a type appropriate to the property (e.g. a font or color
- specifier). For other properties, this could be anything.
-
- If LOCALE is supplied, then instead of returning the actual value,
- the specification(s) for the given locale or locale type will be
- returned. This will only work if the actual value of PROPERTY is
- a specifier (this will always be the case for built-in properties,
- but not or not may apply to user-defined properties). If the
- actual value of PROPERTY is not a specifier, this value will
- simply be returned regardless of LOCALE.
-
- The return value will be a list of instantiators (e.g. strings
- specifying a font or color name), or a list of specifications,
- each of which is a cons of a locale and a list of instantiators.
- Specifically, if LOCALE is a particular locale (a buffer, window,
- frame, device, or `global'), a list of instantiators for that
- locale will be returned. Otherwise, if LOCALE is a locale type
- (one of the symbols `buffer', `window', `frame', or `device'), the
- specifications for all locales of that type will be returned.
- Finally, if LOCALE is `all', the specifications for all locales of
- all types will be returned.
-
- The specifications in a specifier determine what the value of
- PROPERTY will be in a particular "domain" or set of circumstances,
- which is typically a particular Emacs window along with the buffer
- it contains and the frame and device it lies within. The value is
- derived from the instantiator associated with the most specific
- locale (in the order buffer, window, frame, device, and `global')
- that matches the domain in question. In other words, given a
- domain (i.e. an Emacs window, usually), the specifier for PROPERTY
- will first be searched for a specification whose locale is the
- buffer contained within that window; then for a specification
- whose locale is the window itself; then for a specification whose
- locale is the frame that the window is contained within; etc. The
- first instantiator that is valid for the domain (usually this
- means that the instantiator is recognized by the device [i.e. the
- X server or TTY device] that the domain is on). The function
- `face-property-instance' actually does all this, and is used to
- determine how to display the face.
-
- - Function: face-property-instance face property &optional domain
- default no-fallback
- This function returns the instance of FACE's PROPERTY in the
- specified DOMAIN.
-
- Under most circumstances, DOMAIN will be a particular window, and
- the returned instance describes how the specified property
- actually is displayed for that window and the particular buffer in
- it. Note that this may not be the same as how the property
- appears when the buffer is displayed in a different window or
- frame, or how the property appears in the same window if you
- switch to another buffer in that window; and in those cases, the
- returned instance would be different.
-
- The returned instance will typically be a color-instance,
- font-instance, or pixmap-instance object, and you can query it
- using the appropriate object-specific functions. For example, you
- could use `color-instance-rgb-components' to find out the RGB
- (red, green, and blue) components of how the `background' property
- of the `highlight' face is displayed in a particular window. The
- results might be different from the results you would get for
- another window (perhaps the user specified a different color for
- the frame that window is on; or perhaps the same color was
- specified but the window is on a different X server, and that X
- server has different RGB values for the color from this one).
-
- DOMAIN defaults to the selected window if omitted.
-
- DOMAIN can be a frame or device, instead of a window. The value
- returned for a such a domain is used in special circumstances when
- a more specific domain does not apply; for example, a frame value
- might be used for coloring a toolbar, which is conceptually
- attached to a frame rather than a particular window. The value is
- also useful in determining what the value would be for a
- particular window within the frame or device, if it is not
- overridden by a more specific specification.
-
- If PROPERTY does not name a built-in property, its value will
- simply be returned unless it is a specifier object, in which case
- it will be instanced using `specifier-instance'.
-
- Optional arguments DEFAULT and NO-FALLBACK are the same as in
- `specifier-instance'. *Note Specifiers::.

+
+ -- Function: set-face-property face property value &optional locale
+ tag-set how-to-add
+ This function changes a property of a FACE.
+
+ For built-in properties, the actual value of the property is a
+ specifier and you cannot change this; but you can change the
+ specifications within the specifier, and that is what this
+ function will do. For user-defined properties, you can use this
+ function to either change the actual value of the property or, if
+ this value is a specifier, change the specifications within it.
+
+ If PROPERTY is a built-in property, the specifications to be added
+ to this property can be supplied in many different ways:
+
+ If VALUE is a simple instantiator (e.g. a string naming a
+ font or color) or a list of instantiators, then the
+ instantiator(s) will be added as a specification of the
+ property for the given LOCALE (which defaults to `global' if
+ omitted).
+
+ If VALUE is a list of specifications (each of which is a cons
+ of a locale and a list of instantiators), then LOCALE must be
+ `nil' (it does not make sense to explicitly specify a locale
+ in this case), and specifications will be added as given.
+
+ If VALUE is a specifier (as would be returned by
+ `face-property' if no LOCALE argument is given), then some or
+ all of the specifications in the specifier will be added to
+ the property. In this case, the function is really
+ equivalent to `copy-specifier' and LOCALE has the same
+ semantics (if it is a particular locale, the specification
+ for the locale will be copied; if a locale type,
+ specifications for all locales of that type will be copied;
+ if `nil' or `all', then all specifications will be copied).
+
+ HOW-TO-ADD should be either `nil' or one of the symbols `prepend',
+ `append', `remove-tag-set-prepend', `remove-tag-set-append',
+ `remove-locale', `remove-locale-type', or `remove-all'. See
+ `copy-specifier' and `add-spec-to-specifier' for a description of
+ what each of these means. Most of the time, you do not need to
+ worry about this argument; the default behavior usually is fine.
+
+ In general, it is OK to pass an instance object (e.g. as returned
+ by `face-property-instance') as an instantiator in place of an
+ actual instantiator. In such a case, the instantiator used to
+ create that instance object will be used (for example, if you set
+ a font-instance object as the value of the `font' property, then
+ the font name used to create that object will be used instead).
+ If some cases, however, doing this conversion does not make sense,
+ and this will be noted in the documentation for particular types
+ of instance objects.
+
+ If PROPERTY is not a built-in property, then this function will
+ simply set its value if LOCALE is `nil'. However, if LOCALE is
+ given, then this function will attempt to add VALUE as the
+ instantiator for the given LOCALE, using `add-spec-to-specifier'.
+ If the value of the property is not a specifier, it will
+ automatically be converted into a `generic' specifier.
+
+ -- Function: remove-face-property face property &optional locale
+ tag-set exact-p
+ This function removes a property of a FACE.
+
+ For built-in properties, this is analogous to `remove-specifier'.
+ For more information, *Note Other Specification Functions::.
+
+ When PROPERTY is not a built-in property, this function will just
+ remove its value if LOCALE is `nil' or `all'. However, if LOCALE
+ is other than that, this function will attempt to remove VALUE as
+ the instantiator for the given LOCALE with `remove-specifier'. If
+ the value of the property is not a specifier, it will be converted
+ into a `generic' specifier automatically.
+
+ -- Function: face-property face property &optional locale tag-set
+ exact-p
+ This function returns FACE's value of the given PROPERTY.
+
+ If LOCALE is omitted, the FACE's actual value for PROPERTY will be
+ returned. For built-in properties, this will be a specifier
+ object of a type appropriate to the property (e.g. a font or color
+ specifier). For other properties, this could be anything.
+
+ If LOCALE is supplied, then instead of returning the actual value,
+ the specification(s) for the given locale or locale type will be
+ returned. This will only work if the actual value of PROPERTY is
+ a specifier (this will always be the case for built-in properties,
+ but not or not may apply to user-defined properties). If the
+ actual value of PROPERTY is not a specifier, this value will
+ simply be returned regardless of LOCALE.
+
+ The return value will be a list of instantiators (e.g. strings
+ specifying a font or color name), or a list of specifications,
+ each of which is a cons of a locale and a list of instantiators.
+ Specifically, if LOCALE is a particular locale (a buffer, window,
+ frame, device, or `global'), a list of instantiators for that
+ locale will be returned. Otherwise, if LOCALE is a locale type
+ (one of the symbols `buffer', `window', `frame', or `device'), the
+ specifications for all locales of that type will be returned.
+ Finally, if LOCALE is `all', the specifications for all locales of
+ all types will be returned.
+
+ The specifications in a specifier determine what the value of
+ PROPERTY will be in a particular "domain" or set of circumstances,
+ which is typically a particular Emacs window along with the buffer
+ it contains and the frame and device it lies within. The value is
+ derived from the instantiator associated with the most specific
+ locale (in the order buffer, window, frame, device, and `global')
+ that matches the domain in question. In other words, given a
+ domain (i.e. an Emacs window, usually), the specifier for PROPERTY
+ will first be searched for a specification whose locale is the
+ buffer contained within that window; then for a specification
+ whose locale is the window itself; then for a specification whose
+ locale is the frame that the window is contained within; etc. The
+ first instantiator that is valid for the domain (usually this
+ means that the instantiator is recognized by the device [i.e. the
+ X server or TTY device] that the domain is on). The function
+ `face-property-instance' actually does all this, and is used to
+ determine how to display the face.
+
+ -- Function: face-property-instance face property &optional domain
+ default no-fallback
+ This function returns the instance of FACE's PROPERTY in the
+ specified DOMAIN.
+
+ Under most circumstances, DOMAIN will be a particular window, and
+ the returned instance describes how the specified property
+ actually is displayed for that window and the particular buffer in
+ it. Note that this may not be the same as how the property
+ appears when the buffer is displayed in a different window or
+ frame, or how the property appears in the same window if you
+ switch to another buffer in that window; and in those cases, the
+ returned instance would be different.
+
+ The returned instance will typically be a color-instance,
+ font-instance, or pixmap-instance object, and you can query it
+ using the appropriate object-specific functions. For example, you
+ could use `color-instance-rgb-components' to find out the RGB
+ (red, green, and blue) components of how the `background' property
+ of the `highlight' face is displayed in a particular window. The
+ results might be different from the results you would get for
+ another window (perhaps the user specified a different color for
+ the frame that window is on; or perhaps the same color was
+ specified but the window is on a different X server, and that X
+ server has different RGB values for the color from this one).
+
+ DOMAIN defaults to the selected window if omitted.
+
+ DOMAIN can be a frame or device, instead of a window. The value
+ returned for a such a domain is used in special circumstances when
+ a more specific domain does not apply; for example, a frame value
+ might be used for coloring a toolbar, which is conceptually
+ attached to a frame rather than a particular window. The value is
+ also useful in determining what the value would be for a
+ particular window within the frame or device, if it is not
+ overridden by a more specific specification.
+
+ If PROPERTY does not name a built-in property, its value will
+ simply be returned unless it is a specifier object, in which case
+ it will be instanced using `specifier-instance'.
+
+ Optional arguments DEFAULT and NO-FALLBACK are the same as in
+ `specifier-instance'. *Note Specifiers::.

+
+ -- Command: set-face-foreground face color &optional locale tag-set
+ how-to-add
+ -- Command: set-face-background face color &optional locale tag-set
+ how-to-add
+ These functions set the foreground (respectively, background)
+ color of face FACE to COLOR. The argument COLOR should be a

+ `make-color' (*note Colors::).
+
+ -- Command: set-face-background-pixmap face pixmap &optional locale
+ tag-set how-to-add
+ This function sets the background pixmap of face FACE to PIXMAP.
+ The argument PIXMAP should be a string (the name of a bitmap or
+ pixmap file; the directories listed in the variable
+ `x-bitmap-file-path' will be searched) or a glyph object as
+ returned by `make-glyph' (*note Glyphs::). The argument may also
+ be a list of the form `(WIDTH HEIGHT DATA)' where WIDTH and HEIGHT

+
+ Similarly to how the glyph's image specifier works *Note Creating
+ Glyphs::, you don't create your own image specifier, but rather add

+In XEmacs, "glyph" does *not* refer to a single unit of textual display
+(the XEmacs term for that is "rune", and runes are confined to the
+internal implementation of redisplay), but rather is an object
+encapsulating a graphical element, such as an image or widget (an
+active GUI element such as a button or text entry field; X11 calls this
+a "widget", while MS Windows uses the term "control"). This graphical
+element could appear in a buffer, a margin, a gutter, or a toolbar, or
+even externally to XEmacs as a mouse pointer or an icon, for example.
+
+ On the other hand, by contrast with GNU Emacs 21, an XEmacs glyph is
+not "just" an image. The actual image that is displayed (as opposed to
+its position or clipping) is defined by an "image specifier" object
+contained within the glyph. The separation between an image specifier
+object and a glyph object is made because the glyph includes other
+properties than just the actual image: e.g. the face it is displayed in,
+the alignment of the image, _etc_. Also, an image specifier is used in
+at least one place in XEmacs in lieu of a glyph, namely the backing
+pixmap of a face.
+
+ An image specifier is used because glyphs often have locale-specific
+semantics. The most important example is semantics determined by the
+display device: you can't usefully display a JPEG on stdout, or a color
+image on a monochrome display. But because the image property is a
+specifier in XEmacs, you can specify that a given glyph appear as a
+monochrome image on monochrome displays, a color image on color
+displays, and as a string on TTYs. (Specifying a string for the `tty'
+device locale would give behavior like the `ALT' attribute of an `IMG'
+element in HTML.) Another is semantics determined by the buffer or
+mode. (Unfortunately, currently there are no compelling examples of
+this for glyphs.)
+
+ All this means that only one global glyph needs to exist for a
+particular purpose (e.g. the icon used to represent an iconified frame,
+the mouse pointer used over particular areas of a frame, etc.). Often
+you need not (and should not!) create your own glyph, but rather modify
+an existing one.
+
+ In working with glyphs it is important to keep in mind the
+distinction between a locale and a domain. A "locale" is specified by
+the programmer, and is an abstract link between a specification (for a
+glyph, its visual appearance) and a displayable object. The displayable
+object may be a buffer or a window, or an object containing buffers or
+windows such as frame, device, or console. A "domain" is an actual
+display context, which must be concrete enough to enable XEmacs to
+identify the device type. (Buffers may be displayed in windows on
+different devices, even simultaneously, so a buffer cannot be a domain.
+Similarly, the global locale cannot be a domain.) *Note Specifiers::,

-Creating Glyphs
----------------
+50.2 Images
+===========
- - Function: make-glyph &optional spec-list type
- This function creates a new glyph object of type TYPE.
+* Menu:
- SPEC-LIST is used to initialize the glyph's image. It is
- typically an image instantiator (a string or a vector; *Note Image
- Specifiers::), but can also be a list of such instantiators (each
- one in turn is tried until an image is successfully produced), a
- cons of a locale (frame, buffer, etc.) and an instantiator, a list
- of such conses, or any other form accepted by
- `canonicalize-spec-list'. *Note Specifiers::, for more
- information about specifiers.
-
- TYPE specifies the type of the glyph, which specifies in which
- contexts the glyph can be used, and controls the allowable image
- types into which the glyph's image can be instantiated. TYPE
- should be one of `buffer' (used for glyphs in an extent, the
- modeline, the toolbar, or elsewhere in a buffer), `pointer' (used
- for the mouse-pointer), or `icon' (used for a frame's icon), and
- defaults to `buffer'. *Note Glyph Types::.
-
- A glyph in XEmacs does *NOT* refer to a single unit of textual
- display (the XEmacs term for this is "rune"), but rather is an
- object encapsulating a graphical element, such as an image or
- widget (an element such as a button or text field; "widget" is the
- term for this under X Windows, and it's called a "control" under
- MS Windows). This graphical element could appear in a buffer, a
- margin, a gutter, or a toolbar, or as a mouse pointer or an icon,
- for example.
-
- Creating a glyph using `make-glyph' does not specify _where_ the
- glyph will be used, but it does specify _what_ the glyph will look
- like. In particular, SPEC-LIST is used to specify this, and it's
- used to initialize the glyph's `image' property, which is an image
- specifier. (Note that "image" as used in the context of a glyph's
- `image' property or in the terms "image specifier", "image
- instantiator", or "image instance" does not refer to what people
- normally think of as an image (which in XEmacs is called a
- "pixmap"), but to any graphical element--a pixmap, a widget, or
- even a block of text, when used in the places that call for a
- glyph.) The format of the SPEC-LIST is typically an image
- instantiator (a string or a vector; *Note Image Specifiers::), but
- can also be a list of such instantiators (each one in turn is
- tried until an image is successfully produced), a cons of a locale
- (frame, buffer, etc.) and an instantiator, a list of such conses,
- or any other form accepted by `canonicalize-spec-list'. *Note
- Specifiers::, for more information about specifiers.
-
- If you're not familiar with specifiers, you should be in order to
- understand how glyphs work. The clearest introduction to
- specifiers is in the Lispref manual, available under Info. (Choose
- Help->Info->Info Contents on the menubar or type C-h i.) You can
- also see `make-specifier' for a capsule summary. What's important
- to keep in mind is that a specifier lets you set a different value
- for any particular buffer, window, frame, device, or console.
- This allows for a great deal of flexibility; in particular, only
- one global glyph needs to exist for a particular purpose (e.g. the
- icon used to represent an iconified frame, the mouse pointer used
- over particular areas of a frame, etc.), and in these cases you do
- not create your own glyph, but rather modify the existing one.
-
- As well as using SPEC-LIST to initialize the glyph, you can set
- specifications using `set-glyph-image'. Note that, due to a
- possibly questionable historical design decision, a glyph itself
- is not actually a specifier, but rather is an object containing an
- image specifier (as well as other, seldom-used properties).
- Therefore, you cannot set or access specifications for the glyph's
- image by directly using `set-specifier', `specifier-instance' or
- the like on the glyph; instead use them on `(glyph-image GLYPH)'
- or use the convenience functions `set-glyph-image',
- `glyph-image-instance', and `glyph-image'.
-
- Once you have created a glyph, you specify where it will be used as
- follows:
-
- * To insert a glyph into a buffer, create an extent in the
- buffer and then use `set-extent-begin-glyph' or
- `set-extent-end-glyph' to set a glyph to be displayed at the
- corresponding edge of the extent. (It is common to create
- zero-width extents for this purpose.)
-
- * To insert a glyph into the left or right margin of a buffer,
- first make sure the margin is visible by setting a value for
- the specifiers `left-margin-width' or `right-margin-width'.
- (Not strictly necessary when using margin glyphs with layout
- policy `whitespace'.) Then follow the same procedure above
- for inserting a glyph in a buffer, and then set a non-default
- layout policy for the glyph using
- `set-extent-begin-glyph-layout' or
- `set-extent-end-glyph-layout'. Alternatively, use the
- high-level annotations API (see `make-annotation'). (In point
- of fact, you can also use the annotations API for glyphs in a
- buffer, by setting a layout policy of `text'.)
-
- * To insert a glyph into the modeline, just put the glyph
- directly as one of the modeline elements. (Unfortunately you
- can't currently put a begin glyph or end glyph on one of the
- modeline extents--they're ignored.)
-
- * To insert a glyph into a toolbar, specify it as part of a
- toolbar instantiator (typically set on the specifier
- `default-toolbar'). See `default-toolbar' for more
- information. (Note that it is standard practice to use a
- symbol in place of the glyph list in the toolbar
- instantiator; the symbol is evalled to get the glyph list.
- This facilitates both creating the toolbar instantiator and
- modifying individual glyphs in a toolbar later on. For
- example, you can change the way that the Mail toolbar button
- looks by modifying the value of the variable
- `toolbar-mail-icon' (in general, `toolbar-*-icon') and then
- calling `(set-specifier-dirty-flag default-toolbar)'. (####
- Unfortunately this doesn't quite work the way it should; the
- change will appear in new frames, but not existing ones.
-
- * To insert a glyph into a gutter, create or modify a gutter
- instantiator (typically set on the specifier
- `default-gutter'). Gutter instantiators consist of strings
- or lists of strings, so to insert a glyph, create an extent
- over the string, and use `set-extent-begin-glyph' or
- `set-extent-end-glyph' to set a glyph to be displayed at the
- corresponding edge of the extent, just like for glyphs in a
- buffer.
-
- * To use a glyph as the icon for a frame, you do not actually
- create a new glyph; rather, you change the specifications for
- the existing glyph `frame-icon-glyph'. (Remember that,
- because of the specifier nature of glyphs, you can set
- different values for any particular buffer or frame.)
-
- * To use a glyph as the mouse pointer, in general you do not
- create a new glyph, but rather you change the specifications
- of various existing glyphs, such as `text-pointer-glyph' for
- the pointer used over text, `modeline-pointer-glyph' for the
- pointer used over the modeline, etc. Do an apropos over
- `*-pointer-glyph' to find all of them. (Note also that you
- can temporarily set the mouse pointer to some specific shape
- by using `set-frame-pointer', which takes an image instance,
- as obtained from calling `glyph-image-instance' on a glyph of
- type `pointer' - either one of the above-mentioned variables
- or one you created yourself. (See below for what it means to
- create a glyph of type `pointer'.) This pointer will last
- only until the next mouse motion event is processed or
- certain other things happen, such as creating or deleting a
- window. (In fact, the above-mentioned pointer glyph variables
- are implemented as part of the default handler for mouse
- motion events. If you want to customize this behavior, take a
- look at `mode-motion-hook', or `mouse-motion-handler' if you
- really want to get low-level.)
-
- * To use a glyph to control the shape of miscellaneous
- redisplay effects such as the truncation and continuation
- markers, set the appropriate existing glyph variables, as for
- icons and pointers above. See `continuation-glyph',
- `control-arrow-glyph', `hscroll-glyph',
- `invisible-text-glyph', `octal-escape-glyph', and
- `truncation-glyph'. See also `overlay-arrow-string', an odd
- redisplay leftover which can be set to a glyph you created,
- and will cause the glyph to be displayed on top of the text
- position specified in the marker stored in
- `overlay-arrow-position'.
-
- * To use a glyph in a display table (i.e. to control the
- appearance of any individual character), create the
- appropriate character glyphs and then set a specification for
- the specifier `current-display-table', which controls the
- appearance of characters. You can also set an overriding
- display table for use with text displayed in a particular
- face; see `set-face-display-table' and `make-display-table'.
- #### Note: Display tables do not currently support general
- Mule characters. They will be overhauled at some point to
- support this and to provide other features required under
- Mule.
-
- * To use a glyph as the background pixmap of a face: Note that
- the background pixmap of a face is actually an image
- specifier - probably the only place in XEmacs where an image
- specifier occurs outside of a glyph. Similarly to how the
- glyph's image specifier works, you don't create your own
- image specifier, but rather add specifications to the
- existing one (using `set-face-background-pixmap'). Note that
- the image instance that is generated in order to actually
- display the background pixmap is of type `mono-pixmap',
- meaning that it's a two-color image and the foreground and
- background of the image get filled in with the corresponding
- colors from the face.
-
- It is extremely rare that you will ever have to specify a value for
- TYPE, which should be one of `buffer' (used for glyphs in an
- extent, the modeline, the toolbar, or elsewhere in a buffer),
- `pointer' (used for the mouse-pointer), or `icon' (used for a
- frame's icon), and defaults to `buffer'. The only cases where it
- needs to be specified is when creating icon or pointer glyphs, and
- in both cases the necessary glyphs have already been created at
- startup and are accessed through the appropriate variables, e.g.
- `text-pointer-glyph' (or in general, `*-pointer-glyph') and
- `frame-icon-glyph'. *Note Glyph Types::.

- - Function: make-glyph-internal &optional type
- This function creates a new, uninitialized glyph of type TYPE.
+* Image Specifiers:: Specifying an image's appearance.
+* Image Instantiator Conversion:: Lazy realization of graphics.

- with a TYPE of `pointer'.
+\1f
+File: lispref.info, Node: Image Specifiers, Next: Image Instantiator Conversion, Up: Images
- It is extremely unlikely that you will ever need to create a
- pointer glyph. Instead, you probably want to be calling
- `set-glyph-image' on an existing glyph, e.g. `text-pointer-glyph'.
+50.2.1 Image Specifiers
+-----------------------
- - Function: make-icon-glyph &optional spec-list
- Return a new `pointer-glyph' object with the specification list
- SPEC-LIST. This function is equivalent to calling `make-glyph'
- with a TYPE of `icon'.
+An image specifier is a description of the actual graphical realization
+of a glyph. For example, a typical image description is _the file
+system path to a PNG file_. Since redisplay doesn't know about files,
+and in any case the image may need to be manipulated (_e.g._, a face's
+background pixmap must be clipped and tiled), the PNG file must be
+converted internally to a window system bitmap or pixmap object. We
+describe this process by writing that when XEmacs displays the image,
+it "instantiates" the "image instantiator" into an "image instance".
+Image instances are an internal object type (similar to font instances
+and color instances), describing how the image appears in a particular
+domain. On the other hand, image instantiators, which are just
+descriptions of how the image should appear, are represented using Lisp
+strings or vectors.
+
+ Furthermore the graphical realization will vary, and for some devices
+may not even be a bitmapped graphic. These variations may be controlled
+by the program by specifying different "image instantiators" in
+different locales. This is implemented with an "image specifier", a
+specifier whose specifications are image instantiators.
+
+ Image specifiers are rarely if ever found by themselves. However, an
+image specifier results from calling `glyph-image' on a glyph, or
+retrieving the `background-pixmap' property of a face, and you can
+check if some random object is an image specifier.
+
+ -- Function: image-specifier-p object
+ This function returns non-`nil' if OBJECT is an image specifier.
- It is extremely unlikely that you will ever need to create a
- pointer glyph. Instead, you probably want to be calling
- `set-glyph-image' on an existing glyph, e.g. `text-pointer-glyph'.
+ -- Function: make-image-specifier spec-list
+ This function creates a new image specifier object and initializes
+ it according to SPEC-LIST. *Note Specifiers::.
-\1f
-File: lispref.info, Node: Glyph Properties, Next: Glyph Convenience Functions, Prev: Creating Glyphs, Up: Glyph Functions
+ This function exists mainly for completeness. In practice, you
+rarely, if ever, need to actually create an image specifier. Instead,
+they are implicitly created by the initialization of glyphs and faces,
+and the specifier member of these objects cannot be changed after
+initialization; you may only set the specifications it contains.
-Glyph Properties
-----------------
+ Image instantiators come in many formats: `xbm', `xpm', `gif',
+`jpeg', etc. These denote the format of the data describing the image.
+The resulting image instances also come in many types--`mono-pixmap',
+`color-pixmap', `text', `pointer', etc. This refers to the behavior of
+the image and the sorts of places it can appear. (For example, a
+color-pixmap image has fixed colors specified for it, while a
+mono-pixmap image comes in two unspecified shades "foreground" and
+"background" that are determined from the face of the glyph or
+surrounding text; a text image appears as a string of text and has an
+unspecified foreground, background, and font; a pointer image behaves
+like a mono-pixmap image but can only be used as a mouse pointer
+[mono-pixmap images cannot be used as mouse pointers]; etc.)
+
+ It is important to keep the distinction between image instantiator
+format and image instance type in mind. Typically, a given image
+instantiator format can result in many different image instance types.
+For example, `xpm' can be instanced as `color-pixmap', `mono-pixmap',
+or `pointer'; whereas `cursor-font' can be instanced only as `pointer'.
+On the other hand, a particular image instance type can be generated
+by many different image instantiator formats (e.g. `color-pixmap' can
+be generated by `xpm', `gif', `jpeg', etc.).
-Each glyph has a list of properties, which control all of the aspects of
-the glyph's appearance. The following symbols have predefined meanings:
+ *Note Image Instances::, for a more detailed discussion of image
+instance types.
-`image'
- The image used to display the glyph.
+ An image instantiator should be a string or a vector of the form
-`baseline'
- Percent above baseline that glyph is to be displayed. Only for
- glyphs displayed inside of a buffer.
+ `[FORMAT :KEYWORD VALUE ...]'
-`contrib-p'
- Whether the glyph contributes to the height of the line it's on.
- Only for glyphs displayed inside of a buffer.
+ i.e. a format symbol followed by zero or more alternating
+keyword-value pairs.
-`face'
- Face of this glyph (_not_ a specifier).
+ The form of an instantiator can be checked with
+`valid-instantiator-p' with a TYPE of `image', *Note Specifier
+Validation Functions::.
- - Function: set-glyph-property glyph property value &optional locale
- tag-set how-to-add
- This function changes a property of a GLYPH.
+ For a complete list of the format symbols and their usage, *Note
+Image Instantiator Formats::.
- For built-in properties, the actual value of the property is a
- specifier and you cannot change this; but you can change the
- specifications within the specifier, and that is what this
- function will do. For user-defined properties, you can use this
- function to either change the actual value of the property or, if
- this value is a specifier, change the specifications within it.
+ If the instantiator is a string, it will be converted into a vector
+by looking it up according to the specs in the
+`console-type-image-conversion-list' for the console type of the domain
+(usually a window; sometimes a frame or device) over which the image is
+being instantiated.
+
+ If the instantiator specifies data from a file, the data will be
+read in at the time that the instantiator is added to the image
+specifier (which may be well before the image is actually displayed),
+and the instantiator will be converted into one of the inline-data
+forms, with the filename retained using a `:file' keyword. This
+implies that the file must exist when the instantiator is added to the
+image, but does not need to exist at any other time (e.g. it may safely
+be a temporary file).
+
+ The available keywords are given below. Note that some keywords are
+generally available (for example, the `:data' keyword may be used with
+any format except `nothing'), while others are only available for one
+format (`resource-id' is unique to the `mswindows-resource' format).
+
+`:data'
+ Inline image data. If available for a given format, it may be
+ specified directly by the program, or it may be a cache of file
+ data previously read. When present, it is used to instantiate the
+ image in preference to the file named by the `:file' property.
+
+ The format of inline data is image-format-specific. For example,
+ in pixmap formats, the value should be a string, which is
+ interpreted as an octet-stream representing a bitmap or pixmap.
+ But for text formats, it's string containing the text to be
+ displayed, and for resource formats, it's a string containing the
+ name of the resource.
+
+`:file'
+ Data contained in a file. The value is the name of this file. If
+ both `:data' and `:file' are specified, the image is created from
+ what is specified in `:data' and the string in `:file' becomes the
+ value of the `image-instance-file-name' function when applied to
+ the resulting image-instance. Note that there is nothing to stop a
+ program from changing either the `:file' or the `:data' property,
+ and there is no way to detect such mischief. This means that the
+ data will _not_ be automatically reread if you change the `file'
+ property; you must force it by removing the `:data' property.
+ (One way to do this is replacing the whole specification with a new
+ vector.) This keyword is not valid for instantiator formats
+ `nothing', `string', `formatted-string', `cursor-font', `font',
+ and `autodetect'.
+
+`:mask-data'
+ Inline data for `xbm' and `xface'. This specifies a mask to be
+ used with the bitmap. Pixels which are not set in the mask will
+ not be written to the imaging device. The format is a list of
+ width, height, and bits, as for `:data'.
+
+`:mask-file'
+ For `xbm' and `xface'. This specifies a file containing the mask
+ data. If neither a mask file nor inline mask data is given for an
+ XBM image, and the XBM image comes from a file, XEmacs will look
+ for a mask file with the same name as the image file but with
+ `Mask' or `msk' appended. For example, if you specify the XBM file
+ `left_ptr' [usually located in `/usr/include/X11/bitmaps'], the
+ associated mask file `left_ptrmsk' will automatically be picked up.
+
+`:resource-id'
+ Only for `mswindows-resource'. This must be either an integer
+ (which directly specifies a resource number) or a string. See the
+ description of `mswindows-resource' for valid strings. *Note
+ Image Instantiator Formats::.
+
+`:foreground'
+`:background'
+ For `xbm', `xface', `cursor-font', and `font'. These keywords
+ allow you to explicitly specify foreground and background colors.
+ The value should be anything acceptable to `make-color-instance'.
+ This will cause an external format that would by default be
+ instantiated as a `mono-pixmap' to instead be instantiated as a
+ two-color color-pixmap. This can be used to override the colors
+ specified by a glyph's face, for example. If the image is
+ instantiated as a pointer, they specify its foreground and/or
+ background, instead of the defaults of black and white.
+
+`:hotspot-x'
+`:hotspot-y'
+ For `xbm' and `xface'. These keywords specify a hotspot if the
+ image is instantiated as a `pointer'. Note that if the XBM image
+ file specifies a hotspot, it will automatically be picked up if no
+ explicit hotspot is given.
+
+`:color-symbols'
+ Only for `xpm'. This specifies an alist that maps strings that
+ specify symbolic color names to the actual color to be used for
+ that symbolic color (in the form of a string or a color-specifier
+ object). If this is not specified, the contents of
+ `xpm-color-symbols' are used to generate the alist.
+
+`:resource-type'
+ Only for `mswindows-resource'. This must be a symbol, either
+ `cursor', `icon', or `bitmap', specifying the type of resource to
+ be retrieved.
+
+`:face'
+ For `inherit' and the widget formats. This specifies the face to
+ inherit from. For widgets this specifies the face to use for
+ display. It defaults to gui-element-face.
+
+`:selected'
+`:active'
+`:suffix'
+`:keys'
+`:style'
+`:filter'
+`:config'
+`:included'
+`:key-sequence'
+`:accelerator'
+`:label'
+`:callback'
+ These keywords, accepted as menu item specs, are also accepted by
+ images instantiated as `widget'. For their semantics, *Note Menu
+ Format::.

+
+50.2.2 Image Instantiator Conversion
+------------------------------------
+
+Conversion is applied to image instantiators at the time they are added
+to an image specifier or at the time they are passed to
+`make-image-instance'.
+
+ -- Function: set-console-type-image-conversion-list console-type list
+ This function sets the image-conversion-list for consoles of the
+ given CONSOLE-TYPE. The image-conversion-list specifies how image
+ instantiators that are strings should be interpreted. Each
+ element of the list should be a list of two elements (a regular
+ expression string and a vector) or a list of three elements (the
+ preceding two plus an integer index into the vector). The string
+ is converted to the vector associated with the first matching
+ regular expression. If a vector index is specified, the string
+ itself is substituted into that position in the vector.
+
+ Note: The conversion above is applied when the image instantiator
+ is added to an image specifier, not when the specifier is actually
+ instantiated. Therefore, changing the image-conversion-list only
+ affects newly-added instantiators. Existing instantiators in
+ glyphs and image specifiers will not be affected.
+
+ -- Function: console-type-image-conversion-list console-type
+ This function returns the image-conversion-list for consoles of
+ the given CONSOLE-TYPE.
+

+File: lispref.info, Node: Image Instantiator Formats, Next: Image Instances, Prev: Image Instantiator Conversion, Up: Images
+
+50.2.3 Image Instantiator Formats
+---------------------------------
+
+The "format" field of an image instantiator should be a symbol denoting
+a valid format. Which formats are valid will depend on the features
+(such as image decoding libraries) available, on platform support (MS
+Windows resource IDs make no sense on other platforms), and on the
+locale.
+
+ -- Function: valid-image-instantiator-format-p format &optional locale
+ This function returns non-`nil' if FORMAT is a valid image
+ instantiator format.
+
+ If LOCALE is non-`nil' then the format is checked in that locale.
+ If LOCALE is `nil' the current console is used.
+
+ Note that the return value for many formats listed above depends on
+ whether XEmacs was compiled with support for that format.
+
+ -- Function: image-instantiator-format-list
+ This function returns a list of valid image-instantiator formats.
+
+ Here is a table of image-instantiator formats, giving the keywords
+that are usable with each, and the kinds of instances that may result.
+
+`nothing'
+ Don't display anything; no keywords are valid for this format.
+ Can only be instanced as `nothing'.
+
+`string'
+ Display this image as a text string. Can only be instanced as
+ `text', although support for instancing as `mono-pixmap' should be
+ added. The valid keyword is `:data'. The value should be a
+ string, and it is interpreted as a string of characters.
+
+`formatted-string'
+ Display this image as a text string with replaceable fields,
+ similar to a modeline format string. The valid keyword is `:data'.
+ The value should be a string, and it is interpreted as a string of
+ characters containing format sequences.
+
+ Not currently implemented.
+
+`xbm'
+ An X bitmap; available only if X support was compiled into this
+ XEmacs.
+
+ If used in a buffer glyph, icon glyph, or face background pixmap,
+ it will be instantiated as `mono-pixmap' unless the `:foreground'
+ or `:background' keywords are present. In the latter case it will
+ be instantiated as `color-pixmap' with the two specified colors.
+ (Probably if `:foreground' or `:background' is omitted, it
+ defaults to black or white respectively.) If used in a pointer
+ glyph, it will be instantiated as an `pointer'.
+
+ The valid keywords and their values are
+ `:data'
+ A list containing the height and width of the bitmap as
+ integers, and a string interpreted as a bit vector according
+ to the X11 standard XBM bitmap format, in that order.
+
+ `:file'
+ The name of a file containing standard XBM-format data. If
+ it contains a hotspot specification, it will be parsed and
+ used if the hotspot is not explicitly specified.
+
+ `:mask-data'
+ A list containing the height and width of the bitmap as
+ integers, and a string interpreted as a bit vector according
+ to the X11 standard XBM bitmap format, in that order. This
+ bitmap is interpreted as the clipping region for the bitmap
+ contained in the `:data' property.
+
+ `:mask-file'
+ The name of a file containing standard XBM-format data.
+ Interpreted as the clipping region for the bitmap contained
+ in the `:data' property.
+
+ `:foreground'
+ `:background'
+ These keywords allow you to explicitly specify foreground and
+ background colors. The values should be acceptable to
+ `make-color-instance'.
+
+ `:hotspot-x'
+ `:hotspot-y'
+ Integers denoting the hotspot (mouse pointer position), with
+ (0,0) at the top left corner. If given, these override any
+ specification in the XBM file.
+
+`xpm'
+ An XPM pixmap; only available if XPM support was compiled into
+ this XEmacs.
+
+ Can be instanced as `color-pixmap', `mono-pixmap', or `pointer'.
+
+ XPM is an add-on library for X that was designed to rectify the
+ shortcomings of the XBM format. Many icons and labels used in the
+ XEmacs GUI are still distributed in XPM format (although we are
+ moving to standardize on the PNG format). It is therefore highly
+ desirable that XPM be available in your XEmacs.
+
+ Most implementations of X include the XPM library as a standard
+ part. If your vendor does not, it is highly recommended that you
+ download it and install it. You can get it from the XEmacs FTP
+ site and mirrors, as well as from most sites that distribute X11.
+
+ The valid keywords and their values are
+ `:data'
+ A string interpreted as the contents of a standard XPM file.
+
+ `:file'
+ The name of a file containing standard XPM-format data. If
+ it contains a hotspot specification, it will be parsed and
+ used if the hotspot is not explicitly specified.
+
+ `:hotspot-x'
+ `:hotspot-y'
+ Integers denoting the hotspot (mouse pointer position), with
+ (0,0) at the top left corner. If given, these override any
+ specification in the XBM file. (This may not be true. The
+ original documentation doesn't mention them in connection
+ with XPM, but a pointer needs a hotspot.)
+
+ `:color-symbols'
+ An alist that maps the one- or two-character strings that
+ specify symbolic color names in the XPM file to the actual
+ color to be used for that symbolic color (in the form of a
+ string acceptable as a color instantiator, *Note Color
+ Specifiers::, or a color-specifier object). If this is not
+ specified, the contents of `xpm-color-symbols' are used to
+ generate the alist.
+
+`xface'
+ An X-Face bitmap, used to encode people's faces in e-mail messages;
+ only available if X-Face support was compiled into this XEmacs.
+
+ Will be instanced as `mono-pixmap', `color-pixmap', or `pointer',
+ depending on the target instance type and the presence of color
+ keywords.
+
+ The valid keywords and their values are
+ `:data'
+ A list containing the height and width of the bitmap as
+ integers, and a string interpreted as a bit vector according
+ to the X11 standard XBM bitmap format, in that order.
+
+ `:file'
+ The name of a file containing standard XBM-format data. If
+ it contains a hotspot specification, it will be parsed and
+ used if the hotspot is not explicitly specified.
+
+ `:mask-data'
+ A list containing the height and width of the bitmap as
+ integers, and a string interpreted as a bit vector according
+ to the X11 standard XBM bitmap format, in that order. This
+ bitmap is interpreted as the clipping region for the bitmap
+ contained in the `:data' property.
+
+ `:mask-file'
+ The name of a file containing standard XBM-format data.
+ Interpreted as the clipping region for the bitmap contained
+ in the `:data' property.
+
+ `:foreground'
+ `:background'
+ These keywords allow you to explicitly specify foreground and
+ background colors. The values should be acceptable to
+ `make-color-instance'.
+
+ `:hotspot-x'
+ `:hotspot-y'
+ Integers denoting the hotspot (mouse pointer position), with
+ (0,0) at the top left corner. If given, these override any
+ specification in the XBM file.
+
+`gif'
+`jpeg'
+`png'
+`tiff'
+ These are GIF87- or GIF89-format, JPEG-format, PNG/GIF24-format,
+ and TIFF-format images, respectively. They are available only if
+ appropriate decoding support was built into XEmacs. XEmacs
+ includes GIF decoding functions as a standard part of it, so if
+ you have X support, you will normally have GIF support, unless you
+ explicitly disable it at configure time. If you have development
+ support (both the libraries and the relevant C header files)
+ available when XEmacs is built, the JPEG, PNG, and TIFF libraries
+ will automatically be detected (in the "usual places") and linked
+ into the build.
+
+ Note that PNG is the standard format for images distributed with
+ XEmacs, so it is highly recommended that PNG support be built in.
+
+ All of these instantiators will be instanced as `color-pixmap'.
+
+ The valid keywords and their values are
+ `:data'
+ A string interpreted as the contents of a file containing
+ data in the appropriate standard format.
+
+ `:file'
+ The name of a file containing standard-format data.
+
+`cursor-font'
+ Most window systems provide a set of standard cursors, which in
+ X11 is called a cursor font. Can only be instanced as `pointer'.
+ This should probably be fixed.
+
+ The valid keyword is `:data'. Its value should be a string
+ containing one of the standard cursor-font names, such as `watch'
+ or `right_ptr' under X. More specifically, in the X Window System
+ it may be any of the standard cursor names from appendix B of the
+ Xlib manual, provided in the file `<X11/cursorfont.h>' by most
+ distributions, minus the `XC_' prefix. For MS Windows, use
+ `mswindows-resource' instantiator format, not `cursor-font'.
+ Other window systems may have different lists.
+
+`font'
+ A glyph from a font; i.e. the name of a font, and glyph index into
+ it of the form `FONT fontname index [[mask-font] mask-index]'.
+ Only if X support was compiled into this XEmacs. Currently can
+ only be instanced as `pointer'. This should probably be fixed.
+
+`mswindows-resource'
+ An MS Windows pointer resource. Specifies a resource to retrieve
+ directly from the system (an OEM resource) or from a file,
+ particularly an executable file. Can be instanced as `pointer' or
+ `color-pixmap'.
+
+ The valid keywords and their values are
+
+ `:resource-type'
+ A string naming the type (`cursor', `bitmap', or `icon') of
+ the resource. Required.
+
+ `:file'
+ A string containing the name of the file containing the
+ resource (often an executable). If a system resource,
+ `:file' should be omitted.
+
+ `:resource-id'
+ A string containing the name of a resource. Required if
+ `:file' is not specified.
+
+ This must be either an integer (which directly specifies a
+ resource number) or a string. Valid strings are
+
+ For bitmaps:
+
+ "close", "uparrow", "dnarrow", "rgarrow", "lfarrow",
+ "reduce", "zoom", "restore", "reduced", "zoomd", "restored",
+ "uparrowd", "dnarrowd", "rgarrowd", "lfarrowd", "mnarrow",
+ "combo", "uparrowi", "dnarrowi", "rgarrowi", "lfarrowi",
+ "size", "btsize", "check", "checkboxes", and "btncorners".
+
+ For cursors:
+
+ "normal", "ibeam", "wait", "cross", "up", "sizenwse",
+ "sizenesw", "sizewe", "sizens", "sizeall", and "no".
+
+ For icons:
+
+ "sample", "hand", "ques", "bang", "note", and "winlogo".
+
+`subwindow'
+ An embedded windowing system window. Can only be instanced as
+ `subwindow'. Not implemented.
+
+`button'
+ A button widget; either a push button, radio button or toggle
+ button. Can only be instanced as `widget'.
+
+`combo-box'
+ A drop list of selectable items in a widget, for editing text.
+ Can only be instanced as `widget'.
+
+`edit-field'
+ A text editing widget. Can only be instanced as `widget'.
+
+`label'
+ A static, text-only, widget; for displaying text. Can only be
+ instanced as `widget'.
+
+`layout'
+ A widget for controlling the positioning of children underneath it.
+ Through the use of nested layouts, a widget hierarchy can be
+ created which can have the appearance of any standard dialog box
+ or similar arrangement; all of this is counted as one "glyph" and
+ could appear in many of the places that expect a single glyph.
+ Can only be instanced as `widget'.
+
+`native-layout'
+ The native version of a layout widget. Can only be instanced as
+ `widget'.
+
+`progress-gauge'
+ A sliding widget, for showing progress. Can only be instanced as
+ `widget'.
+
+`tab-control'
+ A tab widget; a series of user selectable tabs. Can only be
+ instanced as `widget'.
+
+`tree-view'
+ A folding widget. Can only be instanced as `widget'.
+
+`scrollbar'
+ A scrollbar widget. Can only be instanced as `widget'.
+
+`autodetect'
+ XEmacs tries to guess what format the data is in. If X support
+ exists, the data string will be checked to see if it names a
+ filename. If so, and this filename contains XBM or XPM data, the
+ appropriate sort of pixmap or pointer will be created. [This
+ includes picking up any specified hotspot or associated mask
+ file.] Otherwise, if `pointer' is one of the allowable
+ image-instance types and the string names a valid cursor-font
+ name, the image will be created as a pointer. Otherwise, the
+ image will be displayed as text. If no X support exists, the
+ image will always be displayed as text.
+
+`inherit'
+ Inherit from the background-pixmap property of a face. Can only be
+ instanced as `mono-pixmap'.
+
+ There are two convenience variables for use with the XBM and XPM
+image formats.
+
+ -- Variable: xpm-color-symbols
+ This variable holds definitions of logical color-names used when
+ reading XPM files. Elements of this list should be of the form
+ `(COLOR-NAME FORM-TO-EVALUATE)'. The COLOR-NAME should be a
+ string, which is the name of the color to define; the
+ FORM-TO-EVALUATE should evaluate to a color specifier object, or a
+ string to be passed to `make-color-instance' (*note Colors::). If
+ a loaded XPM file references a symbolic color called COLOR-NAME,
+ it will display as the computed color instead.
+
+ The default value of this variable defines the logical color names
+ `"foreground"' and `"background"' to be the colors of the
+ `default' face.
+
+ -- Variable: x-bitmap-file-path
+ A list of the directories in which X bitmap files may be found.
+ If `nil', this is initialized from the `"*bitmapFilePath"'
+ resource. This is used by the `make-image-instance' function
+ (however, note that if the environment variable `XBMLANGPATH' is
+ set, it is consulted first).

+50.2.4 Image Instances
+----------------------
+
+Image-instance objects encapsulate the way a particular image (pixmap,
+etc.) is displayed on a particular device.
+
+ In most circumstances, you do not need to directly create image
+instances; use a glyph instead. However, it may occasionally be useful
+to explicitly create image instances, if you want more control over the
+instantiation process.
+
+ -- Function: image-instance-p object

+\1f
+File: lispref.info, Node: Image Instance Types, Next: Image Instance Functions, Up: Image Instances
- If PROPERTY is a built-in property, the specifications to be added
- to this property can be supplied in many different ways:
+50.2.4.1 Image Instance Types
+.............................
- * If VALUE is a simple instantiator (e.g. a string naming a
- pixmap filename) or a list of instantiators, then the
- instantiator(s) will be added as a specification of the
- property for the given LOCALE (which defaults to `global' if
- omitted).
+Image instances come in a number of different types. The type of an
+image instance specifies the nature of the image: Whether it is a text
+string, a mono pixmap, a color pixmap, etc.
- * If VALUE is a list of specifications (each of which is a cons
- of a locale and a list of instantiators), then LOCALE must be
- `nil' (it does not make sense to explicitly specify a locale
- in this case), and specifications will be added as given.
+ The valid image instance types are
- * If VALUE is a specifier (as would be returned by
- `glyph-property' if no LOCALE argument is given), then some
- or all of the specifications in the specifier will be added
- to the property. In this case, the function is really
- equivalent to `copy-specifier' and LOCALE has the same
- semantics (if it is a particular locale, the specification
- for the locale will be copied; if a locale type,
- specifications for all locales of that type will be copied;
- if `nil' or `all', then all specifications will be copied).
+`nothing'
+ Nothing is displayed.
- HOW-TO-ADD should be either `nil' or one of the symbols `prepend',
- `append', `remove-tag-set-prepend', `remove-tag-set-append',
- `remove-locale', `remove-locale-type', or `remove-all'. See
- `copy-specifier' and `add-spec-to-specifier' for a description of
- what each of these means. Most of the time, you do not need to
- worry about this argument; the default behavior usually is fine.
+`text'
+ Displayed as text. The foreground and background colors and the
+ font of the text are specified independent of the pixmap.
+ Typically these attributes will come from the face of the
+ surrounding text, unless a face is specified for the glyph in
+ which the image appears.
- In general, it is OK to pass an instance object (e.g. as returned
- by `glyph-property-instance') as an instantiator in place of an
- actual instantiator. In such a case, the instantiator used to
- create that instance object will be used (for example, if you set
- a font-instance object as the value of the `font' property, then
- the font name used to create that object will be used instead).
- If some cases, however, doing this conversion does not make sense,
- and this will be noted in the documentation for particular types
- of instance objects.
+`mono-pixmap'
+ Displayed as a mono pixmap (a pixmap with only two colors where the
+ foreground and background can be specified independent of the
+ pixmap; typically the pixmap assumes the foreground and background
+ colors of the text around it, unless a face is specified for the
+ glyph in which the image appears).
- If PROPERTY is not a built-in property, then this function will
- simply set its value if LOCALE is `nil'. However, if LOCALE is
- given, then this function will attempt to add VALUE as the
- instantiator for the given LOCALE, using `add-spec-to-specifier'.
- If the value of the property is not a specifier, it will
- automatically be converted into a `generic' specifier.
+`color-pixmap'
+ Displayed as a color pixmap.
- - Function: glyph-property glyph property &optional locale
- This function returns GLYPH's value of the given PROPERTY.
+`pointer'
+ Used as the mouse pointer for a window.
- If LOCALE is omitted, the GLYPH's actual value for PROPERTY will
- be returned. For built-in properties, this will be a specifier
- object of a type appropriate to the property (e.g. a font or color
- specifier). For other properties, this could be anything.
+`subwindow'
+ A child window that is treated as an image. This allows (e.g.)
+ another program to be responsible for drawing into the window.
+ Not currently implemented.
- If LOCALE is supplied, then instead of returning the actual value,
- the specification(s) for the given locale or locale type will be
- returned. This will only work if the actual value of PROPERTY is
- a specifier (this will always be the case for built-in properties,
- but may or may not apply to user-defined properties). If the
- actual value of PROPERTY is not a specifier, this value will
- simply be returned regardless of LOCALE.
+`widget'
+ An active GUI element implemented as a "widget" or "control" of the
+ underlying window system.
- The return value will be a list of instantiators (e.g. vectors
- specifying pixmap data), or a list of specifications, each of
- which is a cons of a locale and a list of instantiators.
- Specifically, if LOCALE is a particular locale (a buffer, window,
- frame, device, or `global'), a list of instantiators for that
- locale will be returned. Otherwise, if LOCALE is a locale type
- (one of the symbols `buffer', `window', `frame', or `device'), the
- specifications for all locales of that type will be returned.
- Finally, if LOCALE is `all', the specifications for all locales of
- all types will be returned.
+ The following functions are used to check whether an image instance
+type is valid in the running XEmacs.
- The specifications in a specifier determine what the value of
- PROPERTY will be in a particular "domain" or set of circumstances,
- which is typically a particular Emacs window along with the buffer
- it contains and the frame and device it lies within. The value is
- derived from the instantiator associated with the most specific
- locale (in the order buffer, window, frame, device, and `global')
- that matches the domain in question. In other words, given a
- domain (i.e. an Emacs window, usually), the specifier for PROPERTY
- will first be searched for a specification whose locale is the
- buffer contained within that window; then for a specification
- whose locale is the window itself; then for a specification whose
- locale is the frame that the window is contained within; etc. The
- first instantiator that is valid for the domain (usually this
- means that the instantiator is recognized by the device [i.e. the
- X server or TTY device] that the domain is on). The function
- `glyph-property-instance' actually does all this, and is used to
- determine how to display the glyph.
+ -- Function: valid-image-instance-type-p type
+ This function returns non-`nil' if TYPE is a valid image instance
+ type.
- - Function: glyph-property-instance glyph property &optional domain
- default no-fallback
- This function returns the instance of GLYPH's PROPERTY in the
- specified DOMAIN.
+ -- Function: image-instance-type-list
+ This function returns a list of the valid image instance types.
- Under most circumstances, DOMAIN will be a particular window, and
- the returned instance describes how the specified property
- actually is displayed for that window and the particular buffer in
- it. Note that this may not be the same as how the property
- appears when the buffer is displayed in a different window or
- frame, or how the property appears in the same window if you
- switch to another buffer in that window; and in those cases, the
- returned instance would be different.
+ The following functions are used to determine the type of an image
+instance.
- The returned instance is an image-instance object, and you can
- query it using the appropriate image instance functions. For
- example, you could use `image-instance-depth' to find out the
- depth (number of color planes) of a pixmap displayed in a
- particular window. The results might be different from the
- results you would get for another window (perhaps the user
- specified a different image for the frame that window is on; or
- perhaps the same image was specified but the window is on a
- different X server, and that X server has different color
- capabilities from this one).
+ -- Function: image-instance-type image-instance
+ Return the type of the given image instance. The return value
+ will be one of `nothing', `text', `mono-pixmap', `color-pixmap',
+ `pointer', `subwindow', or `widget'.
- DOMAIN defaults to the selected window if omitted.
+ -- Function: text-image-instance-p object
+ Return non-`nil' if OBJECT is an image instance of type `text'.
- DOMAIN can be a frame or device, instead of a window. The value
- returned for such a domain is used in special circumstances when a
- more specific domain does not apply; for example, a frame value
- might be used for coloring a toolbar, which is conceptually
- attached to a frame rather than a particular window. The value is
- also useful in determining what the value would be for a
- particular window within the frame or device, if it is not
- overridden by a more specific specification.
+ -- Function: mono-pixmap-image-instance-p object
+ Return non-`nil' if OBJECT is an image instance of type
+ `mono-pixmap'.
- If PROPERTY does not name a built-in property, its value will
- simply be returned unless it is a specifier object, in which case
- it will be instanced using `specifier-instance'.
+ -- Function: color-pixmap-image-instance-p object
+ Return non-`nil' if OBJECT is an image instance of type
+ `color-pixmap'.
- Optional arguments DEFAULT and NO-FALLBACK are the same as in
- `specifier-instance'. *Note Specifiers::.
+ -- Function: pointer-image-instance-p object
+ Return non-`nil' if OBJECT is an image instance of type `pointer'.
- - Function: remove-glyph-property glyph property &optional locale
- tag-set exact-p
- This function removes a property from a glyph. For built-in
- properties, this is analogous to `remove-specifier'. *Note
- remove-specifier-p: Specifiers, for the meaning of the LOCALE,
- TAG-SET, and EXACT-P arguments.
+ -- Function: subwindow-image-instance-p object
+ Return non-`nil' if OBJECT is an image instance of type
+ `subwindow'.
+
+ -- Function: nothing-image-instance-p object
+ Return non-`nil' if OBJECT is an image instance of type `nothing'.
+
+ -- Function: widget-image-instance-p object
+ Return non-`nil' if OBJECT is an image instance of type `widget'.

----------------------------
+50.2.4.2 Image Instance Functions
+.................................
-The following functions are provided for working with specific
-properties of a glyph. Note that these are exactly like calling the
-general functions described above and passing in the appropriate value
-for PROPERTY.
+ -- Function: make-image-instance data &optional domain dest-types
+ noerror
+ This function creates a new image-instance object.
- Remember that if you want to determine the "value" of a specific
-glyph property, you probably want to use the `*-instance' functions.
-For example, to determine whether a glyph contributes to its line
-height, use `glyph-contrib-p-instance', not `glyph-contrib-p'. (The
-latter will return a boolean specifier or a list of specifications, and
-you probably aren't concerned with these.)
+ DATA is an image instantiator, which describes the image (*note
+ Image Specifiers::).
- - Function: glyph-image glyph &optional locale
- This function is equivalent to calling `glyph-property' with a
- property of `image'. The return value will be an image specifier
- if LOCALE is `nil' or omitted; otherwise, it will be a
- specification or list of specifications.
+ DEST-TYPES should be a list of allowed image instance types that
+ can be generated. The DEST-TYPES list is unordered. If multiple
+ destination types are possible for a given instantiator, the "most
+ natural" type for the instantiator's format is chosen. These are
- - Function: set-glyph-image glyph spec &optional locale tag-set
- how-to-add
- This function is equivalent to calling `set-glyph-property' with a
- property of `image'.
+ `XBM'
+ `xface'
+ `mono-pixmap', then `color-pixmap', then `pointer'.
- - Function: glyph-image-instance glyph &optional domain default
- no-fallback
- This function returns the instance of GLYPH's image in the given
- DOMAIN, and is equivalent to calling `glyph-property-instance'
- with a property of `image'. The return value will be an image
- instance.
+ `XPM'
+ `GIF'
+ `JPEG'
+ `PNG'
+ `TIFF'
+ `color-pixmap', then `mono-pixmap', then `pointer'.
- Normally DOMAIN will be a window or `nil' (meaning the selected
- window), and an instance object describing how the image appears
- in that particular window and buffer will be returned.
+ `string'
+ `formatted-string formats'
+ `text', then `mono-pixmap' (not currently implemented), then
+ `color-pixmap' (not currently implemented).
- - Function: glyph-contrib-p glyph &optional locale
- This function is equivalent to calling `glyph-property' with a
- property of `contrib-p'. The return value will be a boolean
- specifier if LOCALE is `nil' or omitted; otherwise, it will be a
- specification or list of specifications.
+ `mswindows-resource'
+ For pointer resources, `pointer'.
- - Function: set-glyph-contrib-p glyph spec &optional locale tag-set
- how-to-add
- This function is equivalent to calling `set-glyph-property' with a
- property of `contrib-p'.
+ For the others, `color-pixmap'.
- - Function: glyph-contrib-p-instance glyph &optional domain default
- no-fallback
- This function returns whether the glyph contributes to its line
- height in the given DOMAIN, and is equivalent to calling
- `glyph-property-instance' with a property of `contrib-p'. The
- return value will be either `nil' or `t'. (Normally DOMAIN will be
- a window or `nil', meaning the selected window.)
+ The other formats can only be instantiated as one type.
- - Function: glyph-baseline glyph &optional locale
- This function is equivalent to calling `glyph-property' with a
- property of `baseline'. The return value will be a specifier if
- LOCALE is `nil' or omitted; otherwise, it will be a specification
- or list of specifications.
+ If you want to control more specifically the order of the types
+ into which an image is instantiated, call `make-image-instance'
+ repeatedly until it succeeds, passing less and less preferred
+ destination types each time.
+
+ If DEST-TYPES is omitted, all possible types are allowed.
+
+ DOMAIN specifies the domain to which the image instance will be
+ attached. This domain is termed the "governing domain". The type
+ of the governing domain depends on the image instantiator format.
+ (Although, more correctly, it should probably depend on the image
+ instance type.) For example, pixmap image instances are specific
+ to a device, but widget image instances are specific to a
+ particular XEmacs window because in order to display such a widget
+ when two windows onto the same buffer want to display the widget,
+ two separate underlying widgets must be created. (That's because
+ a widget is actually a child window-system window, and all
+ window-system windows have a unique existence on the screen.)
+ This means that the governing domain for a pixmap image instance
+ will be some device (most likely, the only existing device),
+ whereas the governing domain for a widget image instance will be
+ some XEmacs window.
+
+ If you specify an overly general DOMAIN (e.g. a frame when a
+ window was wanted), an error is signaled. If you specify an overly
+ specific DOMAIN (e.g. a window when a device was wanted), the
+ corresponding general domain is fetched and used instead. For
+ `make-image-instance', it makes no difference whether you specify
+ an overly specific domain or the properly general domain derived
+ from it. However, it does matter when creating an image instance
+ by instantiating a specifier or glyph (e.g. with
+ `glyph-image-instance'), because the more specific domain causes
+ spec lookup to start there and proceed to more general domains.
+ (It would also matter when creating an image instance with an
+ instantiator format of `inherit', but we currently disallow this.)
+
+ If omitted, DOMAIN defaults to the selected window.
+
+ NOERROR controls what happens when the image cannot be generated.
+ If `nil', an error message is generated. If `t', no messages are
+ generated and this function returns `nil'. If anything else, a
+ warning message is generated and this function returns `nil'.
+
+ -- Function: colorize-image-instance image-instance foreground
+ background
+ This function makes the image instance be displayed in the given
+ colors. Image instances come in two varieties: bitmaps, which are
+ 1 bit deep which are rendered in the prevailing foreground and
+ background colors; and pixmaps, which are of arbitrary depth
+ (including 1) and which have the colors explicitly specified.
+ This function converts a bitmap to a pixmap. If the image
+ instance was a pixmap already, nothing is done (and `nil' is
+ returned). Otherwise `t' is returned.
+
+ The following functions are
+
+ -- Function: image-instance-name image-instance
+ This function returns the name of the given image instance. The
+ name is typically taken from the `:file' property of the
+ instantiator if present, otherwise from the `:data' property.
+
+ -- Function: image-instance-domain image-instance
+ Return the governing domain of the given IMAGE-INSTANCE. The
+ governing domain of an image instance is the domain that the image
+ instance is specific to. It is _NOT_ necessarily the domain that
+ was given to the call to `specifier-instance' that resulted in the
+ creation of this image instance. See `make-image-instance' for
+ more information on governing domains.
+
+ -- Function: image-instance-string image-instance
+ This function returns the string of the given image instance.
+ This will only be non-`nil' for text image instances.
+
+ -- Function: image-instance-file-name image-instance
+ This function returns the file name from which IMAGE-INSTANCE was
+ read, if known.
+
+ -- Function: image-instance-mask-file-name image-instance
+ This function returns the file name from which IMAGE-INSTANCE's
+ mask was read, if known.
- - Function: set-glyph-baseline glyph spec &optional locale tag-set
- how-to-add
- This function is equivalent to calling `set-glyph-property' with a
- property of `baseline'.
+ Pixmaps are considered to be three-dimensional. The height and

+50.3 Using Glyphs
+=================
-Images
-======
+Glyph usage is unfortunately somewhat arcane. (For discussion of
+rationale, *Note Glyphs: (Internals)Glyphs.) Because they are not
+"text," they cannot be inserted directly into a buffer. Instead, they
+are values of properties of extents attached to buffers or strings,
+values of global variables such as mouse pointers, or as a component of
+a complex data structure such as a toolbar initializer. Although these
+uses could probably streamlined, each structure has its own
+requirements. Since glyphs are very flexible, it is possible to create
+applications like the `edit-toolbar' and `xpm-mode' libraries which
+display glyphs in a buffer (for reference while editing) that are
+normally used in a different context.
+
+ Usage of glyphs can roughly be categorized as follows:
+
+*Buffer glyphs*
+ Glyphs that are inserted in a buffer may be used for their own
+ sake (for example, image display in `w3'), as an accurate
+ representation of text that can't be displayed in usual fonts
+ (equation display in `preview-latex'), or as annotations (such as
+ a marginal indication of a bookmark). Glyphs are attached to
+ buffers via extents.
+
+*Redisplay glyphs*
+ Glyphs can be used to create XEmacs-specific "fonts". For example,
+ the character that indicates truncation of lines is implemented as
+ the `truncation-glyph'. It is also possible to have XEmacs
+ display a certain character using a custom glyph, via display
+ tables.
+
+*Frame glyphs*
+ Glyphs are used to control the appearance of various other
+ components of the frame. They can be inserted in the modeline,
+ like the favicons used in Web browsers. They are used to specify
+ the labels on toolbar buttons. Finally, they can be inserted in
+ the gutters. (The difference between a glyph inserted in a gutter
+ and a marginal annotation is that the marginal annotation is tied
+ to the text in the buffer. If the buffer line scrolls out of
+ view, the marginal annotation will, as well. A gutter glyph does
+ not move with the text.)
+
+ Unfortunately, all these uses are special cases, and have their own
+ APIs, in contrast to glyphs in a buffer.
+
+*External glyphs*
+ External glyphs simply allow a consistent API for images. The
+ images are then passed to external software such as the window
+ system itself (mouse cursor shapes) and the window manager (icons
+ to represent minimized windows). XEmacs has no role in managing
+ their use.
+
+*Subwindow and widget glyphs*
+ These do not constitute a context of use, but rather an important
+ class of glyph types. The difference between these and other
+ glyphs is that while their geometry is determined by XEmacs, their
+ behavior is managed separately, by internal mechanisms in the case
+ of widgets, and (possibly) by another process in the case of
+ subwindows.
+
+ Some simple concrete examples showing how to insert a glyph in a
+buffer are presented later. *Note Glyph Examples::.
+
+ "Creating Glyphs" explains how to create glyphs. Creating a glyph
+using `make-glyph' does not specify _where_ the glyph will be used, it
+only specifies _what_ the glyph will look like. The next four sections
+explain how to embed glyphs in different display contexts. Finally,
+the last two sections explain the special considerations of using
+glyphs whose behavior is not determined by the code creating them, but
+by the glyph itself (a "widget" in X11 or "control" in MS Windows or
+Aqua), or even by a separate process.

-Image Specifiers
-----------------
-
-An image specifier is used to describe the actual image of a glyph. It
-works like other specifiers (*note Specifiers::), in that it contains a
-number of specifications describing how the image should appear in a
-variety of circumstances. These specifications are called "image
-instantiators". When XEmacs wants to display the image, it instantiates
-the image into an "image instance". Image instances are their own
-primitive object type (similar to font instances and color instances),
-describing how the image appears in a particular domain. (On the other
-hand, image instantiators, which are just descriptions of how the image
-should appear, are represented using strings or vectors.)
-
- - Function: image-specifier-p object
- This function returns non-`nil' if OBJECT is an image specifier.
- Usually, an image specifier results from calling `glyph-image' on
- a glyph.
+50.3.1 Creating Glyphs
+----------------------
- - Function: make-image-specifier spec-list
- This function creates a new image specifier object and initializes
- it according to SPEC-LIST. *Note Specifiers::.
-
- Note that, in practice, you rarely, if ever, need to actually
- create an image specifier! (This function exists mainly for
- completeness.) Pretty much the only use for image specifiers is to
- control how glyphs are displayed, and the image specifier
- associated with a glyph (the `image' property of a glyph) is
- created automatically when a glyph is created and need not (and
- cannot, for that matter) ever be changed (*note Glyphs::). In
- fact, the design decision to create a separate image specifier
- type, rather than make glyphs themselves be specifiers, is
- debatable--the other properties of glyphs are rarely used and could
- conceivably have been incorporated into the glyph's instantiator.
- The rarely used glyph types (buffer, pointer, icon) could also
- have been incorporated into the instantiator.
+ -- Function: make-glyph &optional spec-list type
+ This function creates a new glyph object of type TYPE.
- Image instantiators come in many formats: `xbm', `xpm', `gif',
-`jpeg', etc. This describes the format of the data describing the
-image. The resulting image instances also come in many
-types--`mono-pixmap', `color-pixmap', `text', `pointer', etc. This
-refers to the behavior of the image and the sorts of places it can
-appear. (For example, a color-pixmap image has fixed colors specified
-for it, while a mono-pixmap image comes in two unspecified shades
-"foreground" and "background" that are determined from the face of the
-glyph or surrounding text; a text image appears as a string of text and
-has an unspecified foreground, background, and font; a pointer image
-behaves like a mono-pixmap image but can only be used as a mouse
-pointer [mono-pixmap images cannot be used as mouse pointers]; etc.) It
-is important to keep the distinction between image instantiator format
-and image instance type in mind. Typically, a given image instantiator
-format can result in many different image instance types (for example,
-`xpm' can be instanced as `color-pixmap', `mono-pixmap', or `pointer';
-whereas `cursor-font' can be instanced only as `pointer'), and a
-particular image instance type can be generated by many different image
-instantiator formats (e.g. `color-pixmap' can be generated by `xpm',
-`gif', `jpeg', etc.).
+ The optional SPEC-LIST is used to initialize the glyph's image.
+ It can be any spec-list of "image instantiator" accepted by
+ `canonicalize-spec-list', *Note Adding Specifications::. An
+ individual image instantiator may be a string, which is converted
+ to a vector according to `console-type-image-conversion-list', or a
+ vector. The vector's first element specifies the _external_ format
+ of the data, such as a string, a PNG file, or an MS Windows
+ resource. This is followed by properties (keyword-value pairs)
+ specifying such information as the name of a file containing an
+ image, or pixmap data directly. *Note Image Specifiers::.
+
+ The optional TYPE specifies the type of the glyph. TYPE should be
+ one of `buffer' (used for glyphs in an extent, the modeline, the
+ toolbar, or elsewhere in a frame), `pointer' (used for the
+ mouse-pointer), or `icon' (used for a frame's icon), and defaults
+ to `buffer'.
+
+ SPEC-LIST is the initializer for the glyph's `image' property, which
+is an image specifier. (Note that "image" as used in the context of a
+glyph's `image' property or in the terms "image specifier", "image
+instantiator", or "image instance" does not refer to what people
+normally think of as an image (which in XEmacs is called a "pixmap"),
+but to any graphical element--a pixmap, a widget, or even a block of
+text, when used in the places that call for a glyph.)
+
+ The most common form of SPEC-LIST is a single image instantiator.
+(*Compatibility note:* in GNU Emacs 21, a string used to instantiate an
+image is interpreted as the name of an image file, which is searched
+for and instantiated.) The conversion controlled by
+`console-type-image-conversion-list' typically attempts to look up the
+string as a file name in XEmacs's data directory path, and if this
+fails, defaults to displaying the string as a text image instance
+(_i.e._. the string itself.
+
+ Fine control of a particular specification is provided by using a
+vector as the image instantiator. More complicated instantiators allow
+lists of instantiators to be specified (which are tried in order), or
+mappings from locales to lists of instantiators, _etc_. *Note
+Specifiers::, for more information about specification formats.
+
+ As well as using SPEC-LIST to initialize the glyph, you can set
+specifications using `set-glyph-image'. The glyph itself is not
+actually a specifier, but rather is an object containing an image
+specifier (as well as other properties seldom set by user code).
+Therefore, you cannot set or access specifications for the glyph's image
+by directly using `set-specifier', `specifier-instance' or the like on
+the glyph; instead use them on `(glyph-image GLYPH)' or use the
+convenience functions `set-glyph-image', `glyph-image-instance', and
+`glyph-image'.
+
+ Glyph types reflect the fact that glyphs are used in contexts like
+pointers and window manager icons, which are defined by external
+programs such as the window system or window manager. These require
+somewhat different _internal_ format, which is opaque to the user.
+
+ It is extremely rare that you will ever have to specify a value for
+TYPE, which should be one of `buffer' (used for glyphs in an extent,
+the modeline, the toolbar, or elsewhere in a buffer), `pointer' (used
+for the mouse-pointer), or `icon' (used for a frame's icon), and
+defaults to `buffer'. The only cases where it needs to be specified is
+when creating icon or pointer glyphs, and in both cases the necessary
+glyphs have already been created at startup and are accessed through
+the appropriate variables, e.g. `text-pointer-glyph' (or in general, any
+`*-pointer-glyph') and `frame-icon-glyph'. User code should never need
+to create `pointer' or `icon' glyphs. *Note Glyph Types::.
+
+ There are a few other glyph creation functions, normally used only
+internally or at XEmacs initialization.
+
+ -- Function: make-glyph-internal &optional type
+ This function creates a new, uninitialized glyph of type TYPE.
- *Note Image Instances::, for a more detailed discussion of image
-instance types.
+ -- Function: make-pointer-glyph &optional spec-list
+ Return a new `pointer-glyph' object with the specification list
+ SPEC-LIST. This function is equivalent to calling `make-glyph'
+ with a TYPE of `pointer'.
- An image instantiator should be a string or a vector of the form
+ `make-pointer-glyph' is normally used only by XEmacs initialization
+code. It is extremely unlikely that you will ever need to create a
+pointer glyph. Instead, you probably want to be calling
+`set-glyph-image' on an existing glyph, e.g. `text-pointer-glyph'.
- `[FORMAT :KEYWORD VALUE ...]'
+ -- Function: make-icon-glyph &optional spec-list
+ Return a new `icon-glyph' object with the specification list
+ SPEC-LIST. This function is equivalent to calling `make-glyph'
+ with a TYPE of `icon'.
- i.e. a format symbol followed by zero or more alternating
-keyword-value pairs. The "format" field should be a symbol, one of
+ `make-icon-glyph' is normally used only by XEmacs initialization
+code. It is extremely unlikely that you will ever need to create a icon
+glyph. Instead, you probably want to be calling `set-glyph-image' on
+the existing glyph, `frame-icon-glyph'.
-`nothing'
- Don't display anything; no keywords are valid for this. Can only
- be instanced as `nothing'.
+\1f
+File: lispref.info, Node: Buffer Glyphs, Next: Redisplay Glyphs, Prev: Creating Glyphs, Up: Using Glyphs
-`string'
- Display this image as a text string. Can only be instanced as
- `text', although support for instancing as `mono-pixmap' should be
- added.
+50.3.2 Buffer Glyphs
+--------------------
-`formatted-string'
- Display this image as a text string with replaceable fields,
- similar to a modeline format string; not currently implemented.
+Creating a glyph using `make-glyph' does not specify _where_ the glyph
+will be used, it only specifies _what_ the glyph will look like. Once
+you have created a glyph, you specify where it will be used by
+attaching it to an extent as a _begin-glyph_ or _end-glyph_.
+
+`buffer text'
+ To insert a glyph into a buffer, create an extent in the buffer
+ and then use `set-extent-begin-glyph' or `set-extent-end-glyph' to
+ set a glyph to be displayed at the corresponding edge of the
+ extent. (It is common to create zero-width extents for this
+ purpose.)
+
+`margins'
+ To insert a glyph into the left or right margin of a buffer, first
+ make sure the margin is visible by setting a value for the
+ specifiers `left-margin-width' or `right-margin-width'. (Not
+ strictly necessary when using margin glyphs with layout policy
+ `whitespace'.) Follow the same procedure above for inserting a
+ glyph in a buffer, then set a non-default layout policy for the
+ glyph using `set-extent-begin-glyph-layout' or
+ `set-extent-end-glyph-layout'. Alternatively, use the high-level
+ annotations API (see `make-annotation'). (In fact, you can also
+ use the annotations API for glyphs in a buffer, by setting a
+ layout policy of `text'.)
-`xbm'
- An X bitmap; only if X support was compiled into this XEmacs. Can
- be instanced as `mono-pixmap', `color-pixmap', or `pointer'.
-`xpm'
- An XPM pixmap; only if XPM support was compiled into this XEmacs.
- Can be instanced as `color-pixmap', `mono-pixmap', or `pointer'.
- XPM is an add-on library for X that was designed to rectify the
- shortcomings of the XBM format. Most implementations of X include
- the XPM library as a standard part. If your vendor does not, it
- is highly recommended that you download it and install it. You
- can get it from the standard XEmacs FTP site, among other places.

+File: lispref.info, Node: Redisplay Glyphs, Next: Frame Glyphs, Prev: Buffer Glyphs, Up: Using Glyphs
-`xface'
- An X-Face bitmap, used to encode people's faces in e-mail messages;
- only if X-Face support was compiled into this XEmacs. Can be
- instanced as `mono-pixmap', `color-pixmap', or `pointer'.
+50.3.3 Redisplay Glyphs
+-----------------------
-`gif'
- A GIF87 or GIF89 image; only if GIF support was compiled into this
- XEmacs. Can be instanced as `color-pixmap'. Note that XEmacs
- includes GIF decoding functions as a standard part of it, so if
- you have X support, you will normally have GIF support, unless you
- explicitly disable it at configure time.
+To use a glyph to control the shape of miscellaneous redisplay effects
+such as the truncation and continuation markers, set the appropriate
+existing glyph variables with `set-glyph-image'. See
+`continuation-glyph', `control-arrow-glyph', `hscroll-glyph',
+`invisible-text-glyph', `octal-escape-glyph', and `truncation-glyph'.
+See also `overlay-arrow-string', an odd redisplay leftover which can be
+set to a glyph you created, and will cause the glyph to be displayed on
+top of the text position specified in the marker stored in
+`overlay-arrow-position'.
+
+ To use a glyph in a display table (i.e. to control the appearance of
+any individual character), create the appropriate character glyphs and
+then set a specification for the specifier `current-display-table',
+which controls the appearance of characters. You can also set an
+overriding display table for use with text displayed in a particular
+face; see `set-face-display-table' and `make-display-table'. ####
+Note: Display tables do not currently support general Mule characters.
+They will be overhauled at some point to support this and to provide
+other features required under Mule. *Note Display Tables::.
+
+ Glyphs are not actually used as the background pixmaps of faces, but
+the API is similar. The background pixmap of a face is actually an
+image specifier - probably the only place in XEmacs where an image
+specifier occurs outside of a glyph. If you would like to use a
+glyph's image as a background pixmap, you can extract it with
+`glyph-image', and then add it to a face. *Note Face Convenience
+Functions::.
+
+ -- Glyph: truncation-glyph
+ This variable specifies what is displayed at the end of truncated
+ lines.
-`jpeg'
- A JPEG-format image; only if JPEG support was compiled into this
- XEmacs. Can be instanced as `color-pixmap'. If you have the JPEG
- libraries present on your system when XEmacs is built, XEmacs will
- automatically detect this and use them, unless you explicitly
- disable it at configure time.
+ -- Glyph: continuation-glyph
+ This variable specifies what is displayed at the end of wrapped
+ lines.
-`png'
- A PNG/GIF24 image; only if PNG support was compiled into this
- XEmacs. Can be instanced as `color-pixmap'.
+ -- Glyph: octal-escape-glyph
+ This variable specifies what to prefix character codes displayed
+ in octal with.
-`tiff'
- A TIFF-format image; only if TIFF support was compiled into this
- XEmacs.
+ -- Glyph: hscroll-glyph
+ This variable specifies what to display at the beginning of
+ horizontally scrolled lines.
-`cursor-font'
- One of the standard cursor-font names, such as `watch' or
- `right_ptr' under X. Under X, this is, more specifically, any of
- the standard cursor names from appendix B of the Xlib manual [also
- known as the file `<X11/cursorfont.h>'] minus the `XC_' prefix. On
- other window systems, the valid names will be specific to the type
- of window system. Can only be instanced as `pointer'.
+ -- Glyph: invisible-text-glyph
+ This variable specifies what to use to indicate the presence of
+ invisible text. This is the glyph that is displayed when an
+ ellipsis is called for, according to `selective-display-ellipses'
+ or `buffer-invisibility-spec'). Normally this is three dots
+ ("...").
-`font'
- A glyph from a font; i.e. the name of a font, and glyph index into
- it of the form `FONT fontname index [[mask-font] mask-index]'.
- Only if X support was compiled into this XEmacs. Currently can
- only be instanced as `pointer', although this should probably be
- fixed.
+ -- Glyph: control-arrow-glyph
+ This variable specifies what to use as an arrow for control
+ characters.
-`mswindows-resource'
- An MS Windows pointer resource. Specifies a resource to retrieve
- directly from the system (an OEM resource) or from a file,
- particularly an executable file. If the resource is to be
- retrieved from a file, use :file and optionally :resource-id.
- Otherwise use :resource-id. Always specify :resource-type to
- specify the type (cursor, bitmap or icon) of the resource.
- Possible values for :resource-id are listed below. Can be
- instanced as `pointer' or `color-pixmap'.

+File: lispref.info, Node: Frame Glyphs, Next: External Glyphs, Prev: Redisplay Glyphs, Up: Using Glyphs
+
+50.3.4 Frame Glyphs
+-------------------
+
+There are also a number of special objects whose appearance is specified
+by a glyph. Most of these a global objects that you update with
+`set-glyph-image', such as mouse pointers. Frame icons, toolbar button
+icons, and the modeline are the main non-text objects which accept
+glyphs as elements.
+
+`modeline'
+ A glyph may be displayed in the modeline by inserting the glyph as
+ one of the elements of the modeline format. (Unfortunately you
+ can't currently put a begin glyph or end glyph on one of the
+ modeline extents--they're ignored.)
+
+`toolbar'
+ To insert a glyph into a toolbar, specify it as the icon part of a
+ toolbar button, which in turn must be part of a toolbar
+ instantiator (typically set on the specifier `default-toolbar').
+ See `default-toolbar' for more information. (As a convenience, you
+ may use a symbol in place of the glyph list in the toolbar button
+ instantiator; the symbol is evalled to get the glyph list. This
+ facilitates both creating the toolbar instantiator and modifying
+ individual glyphs in a toolbar later on. For example, you can
+ change the way that the Mail toolbar button looks by modifying the
+ value of the variable `toolbar-mail-icon' (in general,
+ `toolbar-*-icon') and then calling `(set-specifier-dirty-flag
+ default-toolbar)'. (#### Unfortunately this doesn't quite work
+ the way it should; the change will appear in new frames, but not
+ existing ones, because once an image has been displayed the pixmap
+ replaces the symbol for those domains.)
+
+`gutter'
+ To insert a glyph into a gutter, use `set-extent-begin-glyph' or
+ `set-extent-end-glyph' to set a glyph to be displayed at the
+ corresponding edge of extent in a string, similar to the way you
+ insert glyphs in a buffer. Then insert the string into the gutter
+ *Note Specifying a Gutter::. Glyphs that are frequently used in
+ this way are `tab control' and `progress bar' glyphs.
-`subwindow'
- An embedded windowing system window. Can only be instanced as
- `subwindow'.
-`button'
- A button widget; either a push button, radio button or toggle
- button. Can only be instanced as `widget'.
+\1f
+File: lispref.info, Node: External Glyphs, Next: Native GUI Widgets, Prev: Frame Glyphs, Up: Using Glyphs
-`combo-box'
- A drop list of selectable items in a widget, for editing text.
- Can only be instanced as `widget'.
+50.3.5 External Glyphs
+----------------------
-`edit-field'
- A text editing widget. Can only be instanced as `widget'.
+There are two special kinds of glyph that are not displayed by XEmacs.
+Instead, they are used to set the appearance of iconified frames and the
+mouse pointer. Because these uses are constrained by the window system,
+icons and pointers have their own special types *Note Glyph Types::.
+
+ You may use a glyph as the icon for a frame. Do not create a new
+glyph; instead, change the specifications for the existing glyph
+`frame-icon-glyph' with `set-glyph-image'. This is a unique,
+predefined object. Although the natural usage is to set specifications
+for the global locale or a frame locale, you can also arrange for a
+special icon when a frame's selected window displays a particular buffer
+by using a buffer locale.
+
+ The shape of the mouse pointer when over a particular section of a
+frame is controlled using various glyph variables. Since the image of
+a glyph is a specifier, it can be controlled on a per-buffer,
+per-frame, per-window, or per-device basis.
+
+ To use a glyph as the mouse pointer, in general you do not create a
+new glyph, but rather you change the specifications of various existing
+glyphs, such as `text-pointer-glyph' for the pointer used over text,
+`modeline-pointer-glyph' for the pointer used over the modeline, etc.
+Do an apropos over `pointer-glyph' to find all of them. (Note also
+that you can temporarily set the mouse pointer to some specific shape
+by using `set-frame-pointer', which takes an image instance, as
+obtained from calling `glyph-image-instance' on a glyph of type
+`pointer' - either one of the above-mentioned variables or one you
+created yourself. (See below for what it means to create a glyph of
+type `pointer'.) This pointer will last only until the next mouse
+motion event is processed or certain other things happen, such as
+creating or deleting a window. (In fact, the above-mentioned pointer
+glyph variables are implemented as part of the default handler for
+mouse motion events. If you want to customize this behavior, take a
+look at `mode-motion-hook', or `mouse-motion-handler' if you really
+want to get low-level.)
-`label'
- A static, text-only, widget; for displaying text. Can only be
- instanced as `widget'.
+ You should use `set-glyph-image' to set the following variables,
+_not_ `setq'.
-`layout'
- A widget for controlling the positioning of children underneath it.
- Through the use of nested layouts, a widget hierarchy can be
- created which can have the appearance of any standard dialog box
- or similar arrangement; all of this is counted as one "glyph" and

-`:data'
- Inline data. For most formats above, this should be a string. For
- XBM images, this should be a list of three elements: width,
- height, and a string of bit data. This keyword is not valid for
- instantiator format `nothing'.
+ Internally, these variables are implemented in

-`:file'
- Data is contained in a file. The value is the name of this file.
- If both `:data' and `:file' are specified, the image is created
- from what is specified in `:data' and the string in `:file'
- becomes the value of the `image-instance-file-name' function when
- applied to the resulting image-instance. This keyword is not
- valid for instantiator formats `nothing', `string',
- `formatted-string', `cursor-font', `font', and `autodetect'.
+ -- Function: set-frame-pointer frame image-instance

-`:foreground'
-`:background'
- For `xbm', `xface', `cursor-font', and `font'. These keywords
- allow you to explicitly specify foreground and background colors.
- The argument should be anything acceptable to
- `make-color-instance'. This will cause what would be a
- `mono-pixmap' to instead be colorized as a two-color color-pixmap,
- and specifies the foreground and/or background colors for a pointer
- instead of black and white.

-`:mask-file'
- For `xbm' and `xface'. This specifies a file containing the mask

- for a mask file with the same name as the image file but with
- `Mask' or `msk' appended. For example, if you specify the XBM file
- `left_ptr' [usually located in `/usr/include/X11/bitmaps'], the
- associated mask file `left_ptrmsk' will automatically be picked up.

+Traditionally Emacsen have hidden the GUI apparatus from the Lisp
+programmer, but in XEmacs 21.4 the ability to embed autonomous GUI
+objects, called "native widgets", in text was added to Lisp. They are
+handled as _glyphs_. Unlike traditional XEmacs glyphs such images and
+strings, native widgets are opaque to XEmacs, and must be able to
+redraw themselves because they are implemented as subwindows, not as
+graphics drawn by XEmacs into the text window.
- For cursors:
+ Primitive widgets are coded in C using the underlying GUI toolkit,
+and thus are beyond the scope of the _XEmacs Lisp Reference Manual_.
+However, composite widgets can be created in Lisp using "layouts,"
+which are horizontal or vertical arrays of subwidgets. For example, the
+search dialog is formatted using layouts.

+
+50.3.6.2 Lisp API to Native Widgets
+...................................
+
+Native widgets are manipulated as _glyphs_ (*note Glyphs::). Thus they
+are created using `make-glyph', with a format of one of the widget
+types and a `:data' property specific to the widget being instanced.
+
+ However, there is a technical difference between widgets and other
+kinds of glyphs that is theoretically important. Because widgets are
+active (that is, they can respond to user input events themselves), it
+is possible for the user to become aware that two appearances of the
+"same" glyph are actually separate instances. For example, if a user
+changes an image glyph from red to blue, and the buffer containing the
+glyph appears in more than one window, the user will perceive all the
+appearances to change from red to blue simultaneously. However, suppose
+the glyph is a button glyph (_e.g._, as used in the Customize buffer
+for the Set, Save, and Done buttons). Then if the Customize buffer
+appears in several windows at the same time, and the user clicks on the
+button, she will only perceive the button to be depressed in the window
+where she clicked the button.
+
+ It seems from this example that it is unlikely to be a problem in
+practice. When the user is faced with an active widget, it seems likely
+that attention will focus on the widget being manipulated, and having
+other instances of the widget respond simultaneously might be more
+disconcerting than the actual case.

+50.3.6.3 Layouts
+................
+
+An XEmacs "layout" is a one-dimensional array of glyphs. It is a
+widget for controlling the positioning of children underneath it.
+Through the use of nested layouts, a widget hierarchy can be created
+which can have the appearance of any standard dialog box or similar
+arrangement; all of this is counted as one "glyph" and could appear in
+many of the places that expect a single glyph. (There are also "native
+layouts", but these are undocumented, as are their uses.)
+
+ A layout descriptor is an image instantiator, _i.e._, a vector of
+the form `[FORMAT KEY-1 VALUE-1 KEY-2 VALUE-2 ...]' with format
+`layout', and properties
+
+`:orientation'
+ Specifies the orientation of the contained array of glyphs. The
+ value must be one of the symbols `horizontal' or `vertical'.
+
+`:horizontally-justify'
+ Specifies the horizontal justification of the items in the array.
+ The value must be one of the symbols `:right', `:center', or
+ `:left'.
+
+`:vertically-justify'
+ Specifies the vertical justification of the items in the array.
+ The value must be one of the symbols `:top', `:center', or
+ `:bottom'.
+
+`:justify'
+ Specifies justification. #### not understood.
+
+`:border'
+ A glyph to place in the border. The value must be an image
+ instantiator.
+
+`:items'
+ The glyphs controlled by the layout. The value must be a list of
+ image instantiators.

+`make-search-dialog' in the `dialog-items' library, which makes use of
+recursive layouts.

+========================
- - Function: set-console-type-image-conversion-list console-type list
- This function sets the image-conversion-list for consoles of the

- instantiators that are strings should be interpreted. Each
- element of the list should be a list of two elements (a regular
- expression string and a vector) or a list of three elements (the
- preceding two plus an integer index into the vector). The string
- is converted to the vector associated with the first matching
- regular expression. If a vector index is specified, the string
- itself is substituted into that position in the vector.
+Each glyphs has properties that may be accessed. Most of these can
+also be set after the glyph is initialized, with the exception of the
+glyph's type. This is not a real restriction, as it is almost never
+useful to create glyphs of types other than `buffer'.
- Note: The conversion above is applied when the image instantiator
- is added to an image specifier, not when the specifier is actually
- instantiated. Therefore, changing the image-conversion-list only

-Image Instance Types
-....................
+ For built-in properties, the actual value of the property is a
+ specifier and you cannot change this; but you can change the
+ specifications within the specifier, and that is what this
+ function will do. The glyph face is an exception; it is a face
+ name (a symbol) or a face object, not a specifier. (The face
+ properties themselves are typically specifiers.) For user-defined
+ properties, you can use this function to either change the actual
+ value of the property or, if this value is a specifier, change the
+ specifications within it.
-Image instances come in a number of different types. The type of an
-image instance specifies the nature of the image: Whether it is a text
-string, a mono pixmap, a color pixmap, etc.
+ If PROPERTY is a built-in property, the specifications to be added
+ to this property can be supplied in many different ways:
- The valid image instance types are
+ * If VALUE is a simple instantiator (e.g. a string naming a
+ pixmap filename) or a list of instantiators, then the
+ instantiator(s) will be added as a specification of the
+ property for the given LOCALE (which defaults to `global' if
+ omitted).
-`nothing'
- Nothing is displayed.
+ * If VALUE is a list of specifications (each of which is a cons
+ of a locale and a list of instantiators), then LOCALE must be
+ `nil' (it does not make sense to explicitly specify a locale
+ in this case), and specifications will be added as given.
-`text'
- Displayed as text. The foreground and background colors and the
- font of the text are specified independent of the pixmap.
- Typically these attributes will come from the face of the
- surrounding text, unless a face is specified for the glyph in
- which the image appears.
+ * If VALUE is a specifier (as would be returned by
+ `glyph-property' if no LOCALE argument is given), then some
+ or all of the specifications in the specifier will be added
+ to the property. In this case, the function is really
+ equivalent to `copy-specifier' and LOCALE has the same
+ semantics (if it is a particular locale, the specification
+ for the locale will be copied; if a locale type,
+ specifications for all locales of that type will be copied;
+ if `nil' or `all', then all specifications will be copied).
-`mono-pixmap'
- Displayed as a mono pixmap (a pixmap with only two colors where the
- foreground and background can be specified independent of the
- pixmap; typically the pixmap assumes the foreground and background
- colors of the text around it, unless a face is specified for the
- glyph in which the image appears).
+ HOW-TO-ADD should be either `nil' or one of the symbols `prepend',
+ `append', `remove-tag-set-prepend', `remove-tag-set-append',
+ `remove-locale', `remove-locale-type', or `remove-all'. See
+ `copy-specifier' and `add-spec-to-specifier' for a description of
+ what each of these means. Most of the time, you do not need to
+ worry about this argument; the default behavior usually is fine.
-`color-pixmap'
- Displayed as a color pixmap.
+ In general, it is OK to pass an instance object (e.g. as returned
+ by `glyph-property-instance') as an instantiator in place of an
+ actual instantiator. In such a case, the instantiator used to
+ create that instance object will be used (for example, if you set
+ a font-instance object as the value of the `font' property, then
+ the font name used to create that object will be used instead).
+ In some cases, however, doing this conversion does not make sense,
+ and this will be noted in the documentation for particular types
+ of instance objects.
-`pointer'
- Used as the mouse pointer for a window.
+ If PROPERTY is not a built-in property, then this function will
+ simply set its value if LOCALE is `nil'. However, if LOCALE is
+ given, then this function will attempt to add VALUE as the
+ instantiator for the given LOCALE, using `add-spec-to-specifier'.
+ If the value of the property is not a specifier, it will
+ automatically be converted into a `generic' specifier.
-`subwindow'
- A child window that is treated as an image. This allows (e.g.)
- another program to be responsible for drawing into the window.
- Not currently implemented.
+ -- Function: glyph-property glyph property &optional locale
+ This function returns GLYPH's value of the given PROPERTY.
- - Function: valid-image-instance-type-p type
- This function returns non-`nil' if TYPE is a valid image instance
- type.
+ If LOCALE is omitted, the GLYPH's actual value for PROPERTY will
+ be returned. For built-in properties, this will be a specifier
+ object of a type appropriate to the property (e.g. a font or color
+ specifier). For other properties, this could be anything.
- - Function: image-instance-type-list
- This function returns a list of the valid image instance types.
+ If LOCALE is supplied, then instead of returning the actual value,
+ the specification(s) for the given locale or locale type will be
+ returned. This will only work if the actual value of PROPERTY is
+ a specifier (this will always be the case for built-in properties,
+ but may or may not apply to user-defined properties). If the
+ actual value of PROPERTY is not a specifier, this value will
+ simply be returned regardless of LOCALE.
+
+ The return value will be a list of instantiators (e.g. vectors
+ specifying pixmap data), or a list of specifications, each of
+ which is a cons of a locale and a list of instantiators.
+ Specifically, if LOCALE is a particular locale (a buffer, window,
+ frame, device, or `global'), a list of instantiators for that
+ locale will be returned. Otherwise, if LOCALE is a locale type
+ (one of the symbols `buffer', `window', `frame', or `device'), the
+ specifications for all locales of that type will be returned.
+ Finally, if LOCALE is `all', the specifications for all locales of
+ all types will be returned.
+
+ The specifications in a specifier determine what the value of
+ PROPERTY will be in a particular "domain" or set of circumstances,
+ which is typically a particular Emacs window along with the buffer
+ it contains and the frame and device it lies within. The value is
+ derived from the instantiator associated with the most specific
+ locale (in the order buffer, window, frame, device, and `global')
+ that matches the domain in question. In other words, given a
+ domain (i.e. an Emacs window, usually), the specifier for PROPERTY
+ will first be searched for a specification whose locale is the
+ buffer contained within that window; then for a specification
+ whose locale is the window itself; then for a specification whose
+ locale is the frame that the window is contained within; etc. The
+ first instantiator that is valid for the domain (usually this
+ means that the instantiator is recognized by the device [i.e. the
+ X server or TTY device] that the domain is on). The function
+ `glyph-property-instance' actually does all this, and is used to
+ determine how to display the glyph.
- - Function: image-instance-type image-instance
- This function returns the type of the given image instance. The
- return value will be one of `nothing', `text', `mono-pixmap',
- `color-pixmap', `pointer', or `subwindow'.
+ -- Function: glyph-property-instance glyph property &optional domain
+ default no-fallback
+ This function returns the instance of GLYPH's PROPERTY in the
+ specified DOMAIN.
- - Function: text-image-instance-p object
- This function returns non-`nil' if OBJECT is an image instance of
- type `text'.
+ Under most circumstances, DOMAIN will be a particular window, and
+ the returned instance describes how the specified property
+ actually is displayed for that window and the particular buffer in
+ it. Note that this may not be the same as how the property
+ appears when the buffer is displayed in a different window or
+ frame, or how the property appears in the same window if you
+ switch to another buffer in that window; and in those cases, the
+ returned instance would be different.
- - Function: mono-pixmap-image-instance-p object
- This function returns non-`nil' if OBJECT is an image instance of
- type `mono-pixmap'.
+ The returned instance is an image-instance object, and you can
+ query it using the appropriate image instance functions. For
+ example, you could use `image-instance-depth' to find out the

+ DOMAIN defaults to the selected window if omitted.
- - Function: pointer-image-instance-p object
- This function returns non-`nil' if OBJECT is an image instance of

-Image Instance Functions
-........................
+50.4.2 Glyph Convenience Functions
+----------------------------------
- - Function: make-image-instance data &optional domain dest-types
- noerror
- This function creates a new image-instance object.
+The following functions are provided for working with specific
+properties of a glyph. Note that these are exactly like calling the
+general functions described above and passing in the appropriate value
+for PROPERTY.
- DATA is an image instantiator, which describes the image (*note
- Image Specifiers::).
+ Remember that if you want to determine the "value" of a specific
+glyph property, you probably want to use the `*-instance' functions.
+For example, to determine whether a glyph contributes to its line
+height, use `glyph-contrib-p-instance', not `glyph-contrib-p'. (The
+latter will return a boolean specifier or a list of specifications, and
+you probably aren't concerned with these.)
- DEST-TYPES should be a list of allowed image instance types that
- can be generated. The DEST-TYPES list is unordered. If multiple
- destination types are possible for a given instantiator, the "most
- natural" type for the instantiator's format is chosen. (For XBM,
- the most natural types are `mono-pixmap', followed by
- `color-pixmap', followed by `pointer'. For the other normal image
- formats, the most natural types are `color-pixmap', followed by
- `mono-pixmap', followed by `pointer'. For the string and
- formatted-string formats, the most natural types are `text',
- followed by `mono-pixmap' (not currently implemented), followed by
- `color-pixmap' (not currently implemented). For MS Windows
- resources, the most natural type for pointer resources is
- `pointer', and for the others it's `color-pixmap'. The other
- formats can only be instantiated as one type. (If you want to
- control more specifically the order of the types into which an
- image is instantiated, just call `make-image-instance' repeatedly
- until it succeeds, passing less and less preferred destination
- types each time.
+ -- Function: glyph-image glyph &optional locale
+ This function is equivalent to calling `glyph-property' with a
+ property of `image'. The return value will be an image specifier
+ if LOCALE is `nil' or omitted; otherwise, it will be a
+ specification or list of specifications.
- If DEST-TYPES is omitted, all possible types are allowed.
+ -- Function: set-glyph-image glyph spec &optional locale tag-set
+ how-to-add
+ This function is equivalent to calling `set-glyph-property' with a
+ property of `image'.
- DOMAIN specifies the domain to which the image instance will be
- attached. This domain is termed the "governing domain". The type
- of the governing domain depends on the image instantiator format.
- (Although, more correctly, it should probably depend on the image
- instance type.) For example, pixmap image instances are specific
- to a device, but widget image instances are specific to a
- particular XEmacs window because in order to display such a widget
- when two windows onto the same buffer want to display the widget,
- two separate underlying widgets must be created. (That's because a
- widget is actually a child window-system window, and all
- window-system windows have a unique existence on the screen.) This
- means that the governing domain for a pixmap image instance will
- be some device (most likely, the only existing device), whereas
- the governing domain for a widget image instance will be some
- XEmacs window.
+ -- Function: glyph-image-instance glyph &optional domain default
+ no-fallback
+ This function returns the instance of GLYPH's image in the given
+ DOMAIN, and is equivalent to calling `glyph-property-instance'
+ with a property of `image'. The return value will be an image
+ instance.
- If you specify an overly general DOMAIN (e.g. a frame when a
- window was wanted), an error is signaled. If you specify an overly
- specific DOMAIN (e.g. a window when a device was wanted), the
- corresponding general domain is fetched and used instead. For
- `make-image-instance', it makes no difference whether you specify
- an overly specific domain or the properly general domain derived
- from it. However, it does matter when creating an image instance
- by instantiating a specifier or glyph (e.g. with
- `glyph-image-instance'), because the more specific domain causes
- spec lookup to start there and proceed to more general domains. (It
- would also matter when creating an image instance with an
- instantiator format of `inherit', but we currently disallow this.
- #### We should fix this.) n If omitted, DOMAIN defaults to the
- selected window.
+ Normally DOMAIN will be a window or `nil' (meaning the selected
+ window), and an instance object describing how the image appears
+ in that particular window and buffer will be returned.
- NOERROR controls what happens when the image cannot be generated.
- If `nil', an error message is generated. If `t', no messages are
- generated and this function returns `nil'. If anything else, a
- warning message is generated and this function returns `nil'.
+ -- Function: glyph-contrib-p glyph &optional locale
+ This function is equivalent to calling `glyph-property' with a
+ property of `contrib-p'. The return value will be a boolean
+ specifier if LOCALE is `nil' or omitted; otherwise, it will be a
+ specification or list of specifications.
- - Function: colorize-image-instance image-instance foreground
- background
- This function makes the image instance be displayed in the given
- colors. Image instances come in two varieties: bitmaps, which are
- 1 bit deep which are rendered in the prevailing foreground and
- background colors; and pixmaps, which are of arbitrary depth
- (including 1) and which have the colors explicitly specified.
- This function converts a bitmap to a pixmap. If the image
- instance was a pixmap already, nothing is done (and `nil' is
- returned). Otherwise `t' is returned.
+ -- Function: set-glyph-contrib-p glyph spec &optional locale tag-set
+ how-to-add
+ This function is equivalent to calling `set-glyph-property' with a
+ property of `contrib-p'.
- - Function: image-instance-name image-instance
- This function returns the name of the given image instance.
+ -- Function: glyph-contrib-p-instance glyph &optional domain default
+ no-fallback
+ This function returns whether the glyph contributes to its line
+ height in the given DOMAIN, and is equivalent to calling
+ `glyph-property-instance' with a property of `contrib-p'. The
+ return value will be either `nil' or `t'. (Normally DOMAIN will be
+ a window or `nil', meaning the selected window.)
- - Function: image-instance-domain image-instance
- Return the governing domain of the given IMAGE-INSTANCE. The
- governing domain of an image instance is the domain that the image
- instance is specific to. It is _NOT_ necessarily the domain that
- was given to the call to `specifier-instance' that resulted in the
- creation of this image instance. See `make-image-instance' for
- more information on governing domains.
+ -- Function: glyph-baseline glyph &optional locale
+ This function is equivalent to calling `glyph-property' with a
+ property of `baseline'. The return value will be a specifier if
+ LOCALE is `nil' or omitted; otherwise, it will be a specification
+ or list of specifications.
- - Function: image-instance-string image-instance
- This function returns the string of the given image instance.
- This will only be non-`nil' for text image instances.
+ -- Function: set-glyph-baseline glyph spec &optional locale tag-set
+ how-to-add
+ This function is equivalent to calling `set-glyph-property' with a
+ property of `baseline'.
- - Function: image-instance-file-name image-instance
- This function returns the file name from which IMAGE-INSTANCE was
- read, if known.
+ -- Function: glyph-baseline-instance glyph &optional domain default
+ no-fallback
+ This function returns the instance of GLYPH's baseline value in
+ the given DOMAIN, and is equivalent to calling
+ `glyph-property-instance' with a property of `baseline'. The
+ return value will be an integer or `nil'.
- - Function: image-instance-mask-file-name image-instance
- This function returns the file name from which IMAGE-INSTANCE's
- mask was read, if known.
+ Normally DOMAIN will be a window or `nil' (meaning the selected
+ window), and an instance object describing the baseline value
+ appears in that particular window and buffer will be returned.
- - Function: image-instance-depth image-instance
- This function returns the depth of the image instance. This is 0
- for a mono pixmap, or a positive integer for a color pixmap.
+ -- Function: glyph-face glyph
+ This function returns the face of GLYPH. (Remember, this is not a
+ specifier, but a simple property.)
- - Function: image-instance-height image-instance
- This function returns the height of the image instance, in pixels.
+ -- Function: set-glyph-face glyph face
+ This function changes the face of GLYPH to FACE.

- This function returns the X coordinate of the image instance's
- hotspot, if known. This is a point relative to the origin of the

- the point on the image that sits over the location that the

-Mouse Pointer
-=============
-
-The shape of the mouse pointer when over a particular section of a frame
-is controlled using various glyph variables. Since the image of a glyph
-is a specifier, it can be controlled on a per-buffer, per-frame,
-per-window, or per-device basis.
-
- You should use `set-glyph-image' to set the following variables,
-_not_ `setq'.
-
- - Glyph: text-pointer-glyph
- This variable specifies the shape of the mouse pointer when over
- text.
-
- - Glyph: nontext-pointer-glyph
- This variable specifies the shape of the mouse pointer when over a
- buffer, but not over text. If unspecified in a particular domain,
- `text-pointer-glyph' is used.
-
- - Glyph: modeline-pointer-glyph
- This variable specifies the shape of the mouse pointer when over
- the modeline. If unspecified in a particular domain,
- `nontext-pointer-glyph' is used.
-
- - Glyph: selection-pointer-glyph
- This variable specifies the shape of the mouse pointer when over a
- selectable text region. If unspecified in a particular domain,
- `text-pointer-glyph' is used.
-
- - Glyph: gc-pointer-glyph
- This variable specifies the shape of the mouse pointer when a
- garbage collection is in progress. If the selected window is on a
- window system and this glyph specifies a value (i.e. a pointer
- image instance) in the domain of the selected window, the pointer
- will be changed as specified during garbage collection.
- Otherwise, a message will be printed in the echo area, as
- controlled by `gc-message'.
-
- - Glyph: busy-pointer-glyph
- This variable specifies the shape of the mouse pointer when XEmacs
- is busy. If unspecified in a particular domain, the pointer is
- not changed when XEmacs is busy.
-
- - Glyph: menubar-pointer-glyph
- This variable specifies the shape of the mouse pointer when over
- the menubar. If unspecified in a particular domain, the
- window-system-provided default pointer is used.
-
- - Glyph: scrollbar-pointer-glyph
- This variable specifies the shape of the mouse pointer when over a
- scrollbar. If unspecified in a particular domain, the
- window-system-provided default pointer is used.
-
- - Glyph: toolbar-pointer-glyph
- This variable specifies the shape of the mouse pointer when over a
- toolbar. If unspecified in a particular domain,
- `nontext-pointer-glyph' is used.
-
- Internally, these variables are implemented in
-`default-mouse-motion-handler', and thus only take effect when the
-mouse moves. That function calls `set-frame-pointer', which sets the
-current mouse pointer for a frame.
-
- - Function: set-frame-pointer frame image-instance
- This function sets the mouse pointer of FRAME to the given pointer
- image instance. You should not call this function directly. (If
- you do, the pointer will change again the next time the mouse
- moves.)

This function beeps, or flashes the screen (see `visible-bell'

specifies what device to make the sound on, and defaults to the
selected device.

devices, this is effective only if the Termcap entry for the
terminal type has the visible bell flag (`vb') set.

This variable holds an alist associating names with sounds. When
`beep' or `ding' is called with one of the name symbols, the
associated sound will be generated instead of the standard beep.
Other lisp packages may use other beep types, but these are the
ones that the C kernel of XEmacs uses.

This function reads in an audio file and adds it to `sound-alist'.
The sound file must be in the Sun/NeXT U-LAW format. SOUND-NAME

is specified, the sound will be played at that volume; otherwise,
the value of `bell-volume' will be used.

the device to play the sound on, and defaults to the selected
device.
- - Command: play-sound-file file &optional volume device

program executed and the rest of the strings being the arguments
(process-command (get-process "shell"))
=> ("/bin/csh" "-i")
- - Function: process-id process
+ -- Function: process-id process
This function returns the PID of PROCESS. This is an integer that
distinguishes the process PROCESS from all other processes running
on the same computer at the current time. The PID of a process is
chosen by the operating system kernel when the process is started
and remains constant as long as the process exists.
- - Function: process-name process
+ -- Function: process-name process
This function returns the name of PROCESS.
- - Function: process-status process
+ -- Function: process-status process
This function returns the status of PROCESS as a symbol. The
argument PROCESS must be a process, a buffer, a process name
(string) or a buffer name (string).
In earlier Emacs versions (prior to version 19), the status of a
network connection was `run' if open, and `exit' if closed.
- - Function: process-kill-without-query-p process

This function returns whether PROCESS will be killed without
querying the user, if it is running when XEmacs is exited. The
default value is `nil'.

names the signal, like `SIGSEGV'.
- - Function: process-send-signal signal &optional process current-group
+ -- Function: process-send-signal signal &optional process current-group
This function sends the signal SIGNAL to the process PROCESS. The
following functions can be implemented in terms of
`process-send-signal'.
- - Function: interrupt-process &optional process current-group

This function kills the process PROCESS by sending the signal
`SIGKILL'. This signal kills the subprocess immediately, and
cannot be handled by the subprocess.
- - Function: quit-process &optional process current-group
+ -- Function: quit-process &optional process current-group
This function sends the signal `SIGQUIT' to the process PROCESS.
This signal is the one sent by the "quit character" (usually
`C-\') when you are not inside XEmacs.

This function resumes execution of the process PROCESS by sending
it the signal `SIGCONT'. This presumes that PROCESS was stopped
previously.

This function sends a signal to the process with process id PID,
which need not be a child of XEmacs. The argument SIGNAL
specifies which signal to send.

-Operating System Environment
-============================
+57.3 Operating System Environment
+=================================
XEmacs provides access to variables in the operating system environment
through various functions. These variables include the name of the
system, the user's UID, and so on.
- - Variable: system-type
+ -- Variable: system-type
The value of this variable is a symbol indicating the type of
operating system XEmacs is operating on. Here is a table of the
possible values:
`system-configuration' to distinguish between different operating
systems.
- - Variable: system-configuration
+ -- Variable: system-configuration
This variable holds the three-part configuration name for the
hardware/software configuration of your system, as a string. The
convenient way to test parts of this string is with `string-match'.
- - Function: system-name
+ -- Function: system-name
This function returns the name of the machine you are running on.
(system-name)
=> "prep.ai.mit.edu"
Emacs is confused about the name of your system. The variable is also
useful for constructing frame titles (*note Frame Titles::).
- - Variable: mail-host-address

If this variable is non-`nil', it is used instead of `system-name'
for purposes of generating email addresses. For example, it is
used when constructing the default value of `user-mail-address'.

was dumped. *Note Building XEmacs::.)
- - Command: getenv var &optional interactivep
+ -- Command: getenv var &optional interactivep

as a string. Within XEmacs, the environment variable values are
kept in the Lisp variable `process-environment'.

USER=lewis
SHELL=/bin/csh
HOME=/user/lewis
- - Command: setenv variable &optional value unset
+ -- Command: setenv variable &optional value unset
This command sets the value of the environment variable named
VARIABLE to VALUE. Both arguments should be strings. This
function works by modifying `process-environment'; binding that
variable with `let' is also reasonable practice.
- - Variable: process-environment
+ -- Variable: process-environment
This variable is a list of strings, each describing one environment
variable. The functions `getenv' and `setenv' work by
manipulating this variable.
"SHELL=/bin/csh"
"HOME=/user/lewis")
- - Variable: path-separator
+ -- Variable: path-separator
This variable holds a string which says which character separates
directories in a search path (as found in an environment
variable). Its value is `":"' for Unix and GNU systems, and `";"'
for MS-DOS and Windows NT.
- - Variable: invocation-name
+ -- Variable: invocation-name
This variable holds the program name under which Emacs was
invoked. The value is a string, and does not include a directory
name.
- - Variable: invocation-directory
+ -- Variable: invocation-directory
This variable holds the directory from which the Emacs executable
was invoked, or perhaps `nil' if that directory cannot be
determined.
- - Variable: installation-directory
+ -- Variable: installation-directory
If non-`nil', this is a directory within which to look for the
`lib-src' and `etc' subdirectories. This is non-`nil' when Emacs
can't find those directories in their standard installed
locations, but can find them in a directory related somehow to the
one containing the Emacs executable.
- - Function: load-average &optional use-floats
+ -- Function: load-average &optional use-floats
This function returns a list of the current 1-minute, 5-minute and
15-minute load averages. The values are integers that are 100

usually right, but users often set this themselves when the
default value is not right.
- - Function: user-login-name &optional uid

If you don't specify UID, this function returns the name under
which the user is logged in. If the environment variable `LOGNAME'
is set, that value is used. Otherwise, if the environment variable

This function returns the user name corresponding to Emacs's real
UID. This ignores the effective UID and ignores the environment
variables `LOGNAME' and `USER'.
- - Variable: user-full-name
+ -- Variable: user-full-name
This variable holds the name of the user running this Emacs. It is
initialized at startup time from the value of `NAME' environment
variable. You can change the value of this variable to alter the
result of the `user-full-name' function.
- - Function: user-full-name &optional user
+ -- Function: user-full-name &optional user
This function returns the full name of USER. If USER is `nil', it
defaults to the user running this Emacs. In that case, the value
of `user-full-name' variable, if non-`nil', will be used.

-Flow Control
-============
-
-This section attempts to answer the question "Why does XEmacs choose to
-use flow-control characters in its command character set?" For a
-second view on this issue, read the comments on flow control in the
-`emacs/INSTALL' file from the distribution; for help with Termcap
-entries and DEC terminal concentrators, see `emacs/etc/TERMS'.
-
- At one time, most terminals did not need flow control, and none used
-`C-s' and `C-q' for flow control. Therefore, the choice of `C-s' and
-`C-q' as command characters was uncontroversial. XEmacs, for economy
-of keystrokes and portability, used nearly all the ASCII control
-characters, with mnemonic meanings when possible; thus, `C-s' for
-search and `C-q' for quote.
-
- Later, some terminals were introduced which required these characters
-for flow control. They were not very good terminals for full-screen
-editing, so XEmacs maintainers did not pay attention. In later years,
-flow control with `C-s' and `C-q' became widespread among terminals,
-but by this time it was usually an option. And the majority of users,
-who can turn flow control off, were unwilling to switch to less
-mnemonic key bindings for the sake of flow control.
-
- So which usage is "right", XEmacs's or that of some terminal and
-concentrator manufacturers? This question has no simple answer.
-
- One reason why we are reluctant to cater to the problems caused by
-`C-s' and `C-q' is that they are gratuitous. There are other
-techniques (albeit less common in practice) for flow control that
-preserve transparency of the character stream. Note also that their use
-for flow control is not an official standard. Interestingly, on the
-model 33 teletype with a paper tape punch (which is very old), `C-s'
-and `C-q' were sent by the computer to turn the punch on and off!
-
- As X servers and other window systems replace character-only
-terminals, this problem is gradually being cured. For the mean time,
-XEmacs provides a convenient way of enabling flow control if you want
-it: call the function `enable-flow-control'.
-
- - Command: enable-flow-control &optional argument
- This function enables use of `C-s' and `C-q' for output flow
- control, and provides the characters `C-\' and `C-^' as aliases
- for them using `keyboard-translate-table' (*note Translating
- Input::).
-
- With optional argument ARGUMENT (interactively the prefix
- argument), enable flow control mode if ARGUMENT is positive; else
- disable it.
-
- You can use the function `enable-flow-control-on' in your `.emacs'
-file to enable flow control automatically on certain terminal types.
-
- - Function: enable-flow-control-on &rest termtypes
- This function enables flow control, and the aliases `C-\' and
- `C-^', if the terminal type is one of TERMTYPES. For example:
-
- (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
-
- Here is how `enable-flow-control' does its job:
-
- 1. It sets CBREAK mode for terminal input, and tells the operating
- system to handle flow control, with `(set-input-mode nil t)'.
-
- 2. It sets up `keyboard-translate-table' to translate `C-\' and `C-^'
- into `C-s' and `C-q'. Except at its very lowest level, XEmacs
- never knows that the characters typed were anything but `C-s' and
- `C-q', so you can in effect type them as `C-\' and `C-^' even when
- they are input for other commands. *Note Translating Input::.
-
- If the terminal is the source of the flow control characters, then
-once you enable kernel flow control handling, you probably can make do
-with less padding than normal for that terminal. You can reduce the
-amount of padding by customizing the Termcap entry. You can also
-reduce it by setting `baud-rate' to a smaller value so that XEmacs uses
-a smaller speed when calculating the padding needed. *Note Terminal
-Output::.

-Batch Mode
-==========
-
-The command line option `-batch' causes XEmacs to run noninteractively.
-In this mode, XEmacs does not read commands from the terminal, it does
-not alter the terminal modes, and it does not expect to be outputting
-to an erasable screen. The idea is that you specify Lisp programs to
-run; when they are finished, XEmacs should exit. The way to specify
-the programs to run is with `-l FILE', which loads the library named
-FILE, and `-f FUNCTION', which calls FUNCTION with no arguments.
-
- Any Lisp program output that would normally go to the echo area,
-either using `message' or using `prin1', etc., with `t' as the stream,
-goes instead to XEmacs's standard error descriptor when in batch mode.
-Thus, XEmacs behaves much like a noninteractive application program.
-(The echo area output that XEmacs itself normally generates, such as
-command echoing, is suppressed entirely.)
-
- - Function: noninteractive
- This function returns non-`nil' when XEmacs is running in batch

-that XEmacs is connected to can be determined through general console
-and device functions. *Note Consoles and Devices::. However, there
-are some features of the X Window System that do not generalize well,
-and they are covered specially here.

-
-X Selections
-============
-
-The X server records a set of "selections" which permit transfer of
-data between application programs. The various selections are
-distinguished by "selection types", represented in XEmacs by symbols.
-X clients including XEmacs can read or set the selection for any given
-type.
-
- - Function: x-own-selection data &optional type
- This function sets a "selection" in the X server. It takes two
- arguments: a value, DATA, and the selection type TYPE to assign it
- to. DATA may be a string, a cons of two markers, or an extent.
- In the latter cases, the selection is considered to be the text
- between the markers, or between the extent's endpoints.
-
- Each possible TYPE has its own selection value, which changes
- independently. The usual values of TYPE are `PRIMARY' and
- `SECONDARY'; these are symbols with upper-case names, in accord
- with X Windows conventions. The default is `PRIMARY'.
-
- (In FSF Emacs, this function is called `x-set-selection' and takes
- different arguments.)
-
- - Function: x-get-selection
- This function accesses selections set up by XEmacs or by other X
- clients. It returns the value of the current primary selection.
-
- - Function: x-disown-selection &optional secondary-p
- Assuming we own the selection, this function disowns it. If
- SECONDARY-P is non-`nil', the secondary selection instead of the
- primary selection is discarded.
-
- The X server also has a set of numbered "cut buffers" which can
-store text or other data being moved between applications. Cut buffers
-are considered obsolete, but XEmacs supports them for the sake of X
-clients that still use them.
-
- - Function: x-get-cutbuffer &optional n
- This function returns the contents of cut buffer number N. (This
- function is called `x-get-cut-buffer' in FSF Emacs.)
-
- - Function: x-store-cutbuffer string &optional push
- This function stores STRING into the first cut buffer (cut buffer
- 0).
-
- Normally, the contents of the first cut buffer are simply replaced
- by STRING. However, if optional argument PUSH is non-`nil', the
- cut buffers are rotated. This means that the previous value of
- the first cut buffer moves to the second cut buffer, and the
- second to the third, and so on, moving the other values down
- through the series of cut buffers, kill-ring-style. There are 8
- cut buffers altogether.
-
- Cut buffers are considered obsolete; you should use selections
- instead.
-
- This function has no effect if support for cut buffers was not
- compiled in.
-
- This function is called `x-set-cut-buffer' in FSF Emacs.

- This function retrieves a resource value from the X resource
- manager.
-
- * The first arg is the name of the resource to retrieve, such as
- `"font"'.
-
- * The second arg is the class of the resource to retrieve, like
- `"Font"'.
-
- * The third arg should be one of the symbols `string',
- `integer', `natnum', or `boolean', specifying the type of
- object that the database is searched for.
-
- * The fourth arg is the locale to search for the resources on,
- and can currently be a buffer, a frame, a device, or the
- symbol `global'. If omitted, it defaults to `global'.
-
- * The fifth arg is the device to search for the resources on.
- (The resource database for a particular device is constructed
- by combining non-device- specific resources such any
- command-line resources specified and any app-defaults files
- found [or the fallback resources supplied by XEmacs, if no
- app-defaults file is found] with device-specific resources
- such as those supplied using `xrdb'.) If omitted, it defaults
- to the device of LOCALE, if a device can be derived (i.e. if
- LOCALE is a frame or device), and otherwise defaults to the
- value of `default-x-device'.
-
- * The sixth arg NOERROR, if non-`nil', means do not signal an
- error if a bogus resource specification was retrieved (e.g.
- if a non-integer was given when an integer was requested).
- In this case, a warning is issued instead.
-
- The resource names passed to this function are looked up relative
- to the locale.

- 1. If LOCALE is a buffer, a call
-
- `(x-get-resource "foreground" "Foreground" 'string SOME-BUFFER)'
-
- is an interface to a C call something like
-
- `XrmGetResource (db, "xemacs.buffer.BUFFER-NAME.foreground",
- "Emacs.EmacsLocaleType.EmacsBuffer.Foreground",
- "String");'
-
- 2. If LOCALE is a frame, a call
-
- `(x-get-resource "foreground" "Foreground" 'string SOME-FRAME)'
-
- is an interface to a C call something like
-
- `XrmGetResource (db, "xemacs.frame.FRAME-NAME.foreground",
- "Emacs.EmacsLocaleType.EmacsFrame.Foreground",
- "String");'
-
- 3. If LOCALE is a device, a call
-
- `(x-get-resource "foreground" "Foreground" 'string SOME-DEVICE)'
-
- is an interface to a C call something like
-
- `XrmGetResource (db, "xemacs.device.DEVICE-NAME.foreground",
- "Emacs.EmacsLocaleType.EmacsDevice.Foreground",
- "String");'
-
- 4. If LOCALE is the symbol `global', a call
-
- `(x-get-resource "foreground" "Foreground" 'string 'global)'
-
- is an interface to a C call something like
-
- `XrmGetResource (db, "xemacs.foreground",
- "Emacs.Foreground",
- "String");'
-
- Note that for `global', no prefix is added other than that of the
- application itself; thus, you can use this locale to retrieve
- arbitrary application resources, if you really want to.
-
- The returned value of this function is `nil' if the queried
- resource is not found. If TYPE is `string', a string is returned,
- and if it is `integer', an integer is returned. If TYPE is
- `boolean', then the returned value is the list `(t)' for true,
- `(nil)' for false, and is `nil' to mean "unspecified".
-
- - Function: x-put-resource resource-line &optional device
- This function adds a resource to the resource database for DEVICE.
- RESOURCE-LINE specifies the resource to add and should be a
- standard resource specification.
-
- - Variable: x-emacs-application-class
- This variable holds The X application class of the XEmacs process.
- This controls, among other things, the name of the "app-defaults"
- file that XEmacs will use. For changes to this variable to take
- effect, they must be made before the connection to the X server is
- initialized, that is, this variable may only be changed before
- XEmacs is dumped, or by setting it in the file
- `lisp/term/x-win.el'.
-
- By default, this variable is `nil' at startup. When the connection
- to the X server is first initialized, the X resource database will
- be consulted and the value will be set according to whether any
- resources are found for the application class "XEmacs".

-Data about the X Server
------------------------
-
-This section describes functions and a variable that you can use to get
-information about the capabilities and origin of the X server
-corresponding to a particular device. The device argument is generally
-optional and defaults to the selected device.
-
- - Function: x-server-version &optional device
- This function returns the list of version numbers of the X server
- DEVICE is on. The returned value is a list of three integers: the
- major and minor version numbers of the X protocol in use, and the
- vendor-specific release number.
-
- - Function: x-server-vendor &optional device
- This function returns the vendor supporting the X server DEVICE is
- on.
-
- - Function: x-display-visual-class &optional device
- This function returns the visual class of the display DEVICE is
- on. The value is one of the symbols `static-gray', `gray-scale',
- `static-color', `pseudo-color', `true-color', and `direct-color'.
- (Note that this is different from previous versions of XEmacs,
- which returned `StaticGray', `GrayScale', etc.)

-Restricting Access to the Server by Other Apps
-----------------------------------------------
-
- - Function: x-grab-keyboard &optional device
- This function grabs the keyboard on the given device (defaulting
- to the selected one). So long as the keyboard is grabbed, all
- keyboard events will be delivered to XEmacs--it is not possible
- for other X clients to eavesdrop on them. Ungrab the keyboard
- with `x-ungrab-keyboard' (use an `unwind-protect'). Returns `t'
- if the grab was successful; `nil' otherwise.
-
- - Function: x-ungrab-keyboard &optional device
- This function releases a keyboard grab made with `x-grab-keyboard'.
-
- - Function: x-grab-pointer &optional device cursor ignore-keyboard
- This function grabs the pointer and restricts it to its current
- window. If optional DEVICE argument is `nil', the selected device
- will be used. If optional CURSOR argument is non-`nil', change
- the pointer shape to that until `x-ungrab-pointer' is called (it
- should be an object returned by the `make-cursor' function). If
- the second optional argument IGNORE-KEYBOARD is non-`nil', ignore
- all keyboard events during the grab. Returns `t' if the grab is
- successful, `nil' otherwise.
-
- - Function: x-ungrab-pointer &optional device
- This function releases a pointer grab made with `x-grab-pointer'.
- If optional first arg DEVICE is `nil' the selected device is used.
- If it is `t' the pointer will be released on all X devices.

-Miscellaneous X Functions and Variables
-=======================================
-
- - Variable: x-bitmap-file-path
- This variable holds a list of the directories in which X bitmap
- files may be found. If `nil', this is initialized from the
- `"*bitmapFilePath"' resource. This is used by the
- `make-image-instance' function (however, note that if the
- environment variable `XBMLANGPATH' is set, it is consulted first).
-
- - Variable: x-library-search-path
- This variable holds the search path used by `read-color' to find
- `rgb.txt'.
-
- - Function: x-valid-keysym-name-p keysym
- This function returns true if KEYSYM names a keysym that the X
- library knows about. Valid keysyms are listed in the files
- `/usr/include/X11/keysymdef.h' and in `/usr/lib/X11/XKeysymDB', or
- whatever the equivalents are on your system.
-
- - Function: x-window-id &optional frame
- This function returns the ID of the X11 window. This gives us a
- chance to manipulate the Emacs window from within a different
- program. Since the ID is an unsigned long, we return it as a
- string.
-
- - Variable: x-allow-sendevents
- If non-`nil', synthetic events are allowed. `nil' means they are
- ignored. Beware: allowing XEmacs to process SendEvents opens a
- big security hole.
-
- - Function: x-debug-mode arg &optional device
- With a true arg, make the connection to the X server synchronous.
- With false, make it asynchronous. Synchronous connections are
- much slower, but are useful for debugging. (If you get X errors,
- make the connection synchronous, and use a debugger to set a
- breakpoint on `x_error_handler'. Your backtrace of the C stack
- will now be useful. In asynchronous mode, the stack above
- `x_error_handler' isn't helpful because of buffering.) If DEVICE
- is not specified, the selected device is assumed.
-
- Calling this function is the same as calling the C function
- `XSynchronize', or starting the program with the `-sync' command
- line argument.
-
- - Variable: x-debug-events
- If non-zero, debug information about events that XEmacs sees is
- displayed. Information is displayed on stderr. Currently defined
- values are:
-
- * 1 == non-verbose output
-
- * 2 == verbose output

-XEmacs ToolTalk API Summary
-===========================
-
-The XEmacs Lisp interface to ToolTalk is similar, at least in spirit,
-to the standard C ToolTalk API. Only the message and pattern parts of
-the API are supported at present; more of the API could be added if
-needed. The Lisp interface departs from the C API in a few ways:
-
- * ToolTalk is initialized automatically at XEmacs startup-time.
- Messages can only be sent other ToolTalk applications connected to
- the same X11 server that XEmacs is running on.
-
- * There are fewer entry points; polymorphic functions with keyword
- arguments are used instead.
-
- * The callback interface is simpler and marginally less functional.
- A single callback may be associated with a message or a pattern;
- the callback is specified with a Lisp symbol (the symbol should
- have a function binding).
-
- * The session attribute for messages and patterns is always
- initialized to the default session.
-
- * Anywhere a ToolTalk enum constant, e.g. `TT_SESSION', is valid, one
- can substitute the corresponding symbol, e.g. `'TT_SESSION'. This
- simplifies building lists that represent messages and patterns.

-Example of Sending Messages
----------------------------
-
-Here's a simple example that sends a query to another application and
-then displays its reply. Both the query and the reply are stored in
-the first argument of the message.
-
- (defun tooltalk-random-query-handler (msg)
- (let ((state (get-tooltalk-message-attribute msg 'state)))
- (cond
- ((eq state 'TT_HANDLED)
- (message (get-tooltalk-message-attribute msg arg_val 0)))
- ((memq state '(TT_FAILED TT_REJECTED))
- (message "Random query turns up nothing")))))
-
- (defvar random-query-message
- '( class TT_REQUEST
- scope TT_SESSION
- address TT_PROCEDURE
- op "random-query"
- args '((TT_INOUT "?" "string"))
- callback tooltalk-random-query-handler))

- (send-tooltalk-message m))
-

-
-Elisp Interface for Sending Messages
-------------------------------------
-
- - Function: make-tooltalk-message attributes
- Create a ToolTalk message and initialize its attributes. The
- value of ATTRIBUTES must be a list of alternating keyword/values,
- where keywords are symbols that name valid message attributes.
- For example:
-
- (make-tooltalk-message
- '(class TT_NOTICE
- scope TT_SESSION
- address TT_PROCEDURE
- op "do-something"
- args ("arg1" 12345 (TT_INOUT "arg3" "string"))))
-
- Values must always be strings, integers, or symbols that represent
- ToolTalk constants. Attribute names are the same as those
- supported by `set-tooltalk-message-attribute', plus `args'.
-
- The value of `args' should be a list of message arguments where
- each message argument has the following form:
-
- `(mode [value [type]])' or just `value'
-
- Where MODE is one of `TT_IN', `TT_OUT', or `TT_INOUT' and TYPE is
- a string. If TYPE isn't specified then `int' is used if VALUE is
- a number; otherwise `string' is used. If TYPE is `string' then
- VALUE is converted to a string (if it isn't a string already) with
- `prin1-to-string'. If only a value is specified then MODE
- defaults to `TT_IN'. If MODE is `TT_OUT' then VALUE and TYPE
- don't need to be specified. You can find out more about the
- semantics and uses of ToolTalk message arguments in chapter 4 of
- the `ToolTalk Programmer's Guide'.
-
-
- - Function: send-tooltalk-message msg
- Send the message on its way. Once the message has been sent it's
- almost always a good idea to get rid of it with
- `destroy-tooltalk-message'.
-
-
- - Function: return-tooltalk-message msg &optional mode
- Send a reply to this message. The second argument can be `reply',
- `reject' or `fail'; the default is `reply'. Before sending a
- reply, all message arguments whose mode is `TT_INOUT' or `TT_OUT'
- should have been filled in--see `set-tooltalk-message-attribute'.
-
-
- - Function: get-tooltalk-message-attribute msg attribute &optional argn
- Returns the indicated ToolTalk message attribute. Attributes are
- identified by symbols with the same name (underscores and all) as
- the suffix of the ToolTalk `tt_message_<attribute>' function that
- extracts the value. String attribute values are copied and
- enumerated type values (except disposition) are converted to
- symbols; e.g. `TT_HANDLER' is `'TT_HANDLER', `uid' and `gid' are
- represented by fixnums (small integers), `opnum' is converted to a
- string, and `disposition' is converted to a fixnum. We convert
- `opnum' (a C int) to a string (e.g. `123' => `"123"') because
- there's no guarantee that opnums will fit within the range of
- XEmacs Lisp integers.
-
- [TBD] Use the `plist' attribute instead of C API `user' attribute
- for user-defined message data. To retrieve the value of a message
- property, specify the indicator for ARGN. For example, to get the
- value of a property called `rflag', use
-
- (get-tooltalk-message-attribute msg 'plist 'rflag)
-
- To get the value of a message argument use one of the `arg_val'
- (strings), `arg_ival' (integers), or `arg_bval' (strings with
- embedded nulls), attributes. For example, to get the integer
- value of the third argument:
-
- (get-tooltalk-message-attribute msg 'arg_ival 2)
-
- As you can see, argument numbers are zero-based. The type of each
- arguments can be retrieved with the `arg_type' attribute; however
- ToolTalk doesn't define any semantics for the string value of
- `arg_type'. Conventionally `string' is used for strings and `int'
- for 32 bit integers. Note that XEmacs Lisp stores the lengths of
- strings explicitly (unlike C) so treating the value returned by
- `arg_bval' like a string is fine.
-
-
- - Function: set-tooltalk-message-attribute value msg attribute
- &optional argn
- Initialize one ToolTalk message attribute.
-
- Attribute names and values are the same as for
- `get-tooltalk-message-attribute'. A property list is provided for
- user data (instead of the `user' message attribute); see
- `get-tooltalk-message-attribute'.
-
- Callbacks are handled slightly differently than in the C ToolTalk
- API. The value of CALLBACK should be the name of a function of one
- argument. It will be called each time the state of the message
- changes. This is usually used to notice when the message's state
- has changed to `TT_HANDLED' (or `TT_FAILED'), so that reply
- argument values can be used.
-
- If one of the argument attributes is specified as `arg_val',
- `arg_ival', or `arg_bval', then ARGN must be the number of an
- already created argument. Arguments can be added to a message
- with `add-tooltalk-message-arg'.
-
-
- - Function: add-tooltalk-message-arg msg mode type &optional value
- Append one new argument to the message. MODE must be one of
- `TT_IN', `TT_INOUT', or `TT_OUT', TYPE must be a string, and VALUE
- can be a string or an integer. ToolTalk doesn't define any
- semantics for TYPE, so only the participants in the protocol
- you're using need to agree what types mean (if anything).
- Conventionally `string' is used for strings and `int' for 32 bit
- integers. Arguments can initialized by providing a value or with
- `set-tooltalk-message-attribute'; the latter is necessary if you
- want to initialize the argument with a string that can contain
- embedded nulls (use `arg_bval').
-
-
- - Function: create-tooltalk-message &optional no-callback
- Create a new ToolTalk message. The message's session attribute is
- initialized to the default session. Other attributes can be
- initialized with `set-tooltalk-message-attribute'.
- `make-tooltalk-message' is the preferred way to create and
- initialize a message.
-
- Optional arg NO-CALLBACK says don't add a C-level callback at all.
- Normally don't do that; just don't specify the Lisp callback when
- calling `make-tooltalk-message'.
-
-
- - Function: destroy-tooltalk-message msg
- Apply `tt_message_destroy' to the message. It's not necessary to
- destroy messages after they've been processed by a message or
- pattern callback, the Lisp/ToolTalk callback machinery does this
- for you.

------------------------------
-
-Here's a simple example of a handler for a message that tells XEmacs to
-display a string in the mini-buffer area. The message operation is
-called `emacs-display-string'. Its first (0th) argument is the string
-to display.

---------------------------------------
-
- - Function: make-tooltalk-pattern attributes
- Create a ToolTalk pattern and initialize its attributes. The
- value of attributes must be a list of alternating keyword/values,
- where keywords are symbols that name valid pattern attributes or
- lists of valid attributes. For example:
-
- (make-tooltalk-pattern
- '(category TT_OBSERVE
- scope TT_SESSION
- op ("operation1" "operation2")
- args ("arg1" 12345 (TT_INOUT "arg3" "string"))))
-
- Attribute names are the same as those supported by
- `add-tooltalk-pattern-attribute', plus `'args'.
-
- Values must always be strings, integers, or symbols that represent
- ToolTalk constants or lists of same. When a list of values is
- provided all of the list elements are added to the attribute. In
- the example above, messages whose `op' attribute is `"operation1"'
- or `"operation2"' would match the pattern.
-
- The value of ARGS should be a list of pattern arguments where each
- pattern argument has the following form:
-
- `(mode [value [type]])' or just `value'
-
- Where MODE is one of `TT_IN', `TT_OUT', or `TT_INOUT' and TYPE is
- a string. If TYPE isn't specified then `int' is used if VALUE is
- a number; otherwise `string' is used. If TYPE is `string' then
- VALUE is converted to a string (if it isn't a string already) with
- `prin1-to-string'. If only a value is specified then MODE
- defaults to `TT_IN'. If MODE is `TT_OUT' then VALUE and TYPE
- don't need to be specified. You can find out more about the
- semantics and uses of ToolTalk pattern arguments in chapter 3 of
- the `ToolTalk Programmer's Guide'.
-
-
- - Function: register-tooltalk-pattern pattern
- XEmacs will begin receiving messages that match this pattern.
-
- - Function: unregister-tooltalk-pattern pattern
- XEmacs will stop receiving messages that match this pattern.
-
- - Function: add-tooltalk-pattern-attribute value pattern indicator
- Add one value to the indicated pattern attribute. The names of
- attributes are the same as the ToolTalk accessors used to set them
- less the `tooltalk_pattern_' prefix and the `_add' suffix. For
- example, the name of the attribute for the
- `tt_pattern_disposition_add' attribute is `disposition'. The
- `category' attribute is handled specially, since a pattern can only
- be a member of one category (`TT_OBSERVE' or `TT_HANDLE').
-
- Callbacks are handled slightly differently than in the C ToolTalk
- API. The value of CALLBACK should be the name of a function of one
- argument. It will be called each time the pattern matches an
- incoming message.
-
- - Function: add-tooltalk-pattern-arg pattern mode vtype &optional value
- Add one fully-specified argument to a ToolTalk pattern. MODE must
- be one of `TT_IN', `TT_INOUT', or `TT_OUT'. VTYPE must be a
- string. VALUE can be an integer, string or `nil'. If VALUE is an
- integer then an integer argument (`tt_pattern_iarg_add') is added;
- otherwise a string argument is added. At present there's no way
- to add a binary data argument.
-
-
- - Function: create-tooltalk-pattern
- Create a new ToolTalk pattern and initialize its session attribute
- to be the default session.
-
- - Function: destroy-tooltalk-pattern pattern
- Apply `tt_pattern_destroy' to the pattern. This effectively
- unregisters the pattern.
-
- - Function: describe-tooltalk-message msg &optional stream
- Print the message's attributes and arguments to STREAM. This is
- often useful for debugging.

-
- * OpenLDAP 1.2 (<http://www.openldap.org/>)
-
- * University of Michigan's LDAP 3.3
- (<http://www.umich.edu/~dirsvcs/ldap/>)

-LDAP Variables
---------------
-
- - Variable: ldap-default-host
- The default LDAP server hostname. A TCP port number can be
- appended to that name using a colon as a separator.
-
- - Variable: ldap-default-port
- Default TCP port for LDAP connections. Initialized from the LDAP
- library. Default value is 389.
-
- - Variable: ldap-default-base
- Default base for LDAP searches. This is a string using the syntax
- of RFC 1779. For instance, "o=ACME, c=US" limits the search to the
- Acme organization in the United States.
-
- - Variable: ldap-host-parameters-alist
- An alist of per host options for LDAP transactions. The list
- elements look like `(HOST PROP1 VAL1 PROP2 VAL2 ...)' HOST is the
- name of an LDAP server. A TCP port number can be appended to that
- name using a colon as a separator. PROPN and VALN are
- property/value pairs describing parameters for the server. Valid
- properties:
- `binddn'
- The distinguished name of the user to bind as. This may look
- like `cn=Babs Jensen,o=ACME,c=US', see RFC 1779 for details.
-
- `passwd'
- The password to use for authentication.
-
- `auth'
- The authentication method to use, possible values depend on
- the LDAP library XEmacs was compiled with, they may include
- `simple', `krbv41' and `krbv42'.
-
- `base'
- The base for the search. This may look like `cÿ, o¬me', see
- RFC 1779 for syntax details.
-
- `scope'
- One of the symbols `base', `onelevel' or `subtree' indicating
- the scope of the search limited to a base object, to a single
- level or to the whole subtree.
-
- `deref'
- The dereference policy is one of the symbols `never',
- `always', `search' or `find' and defines how aliases are
- dereferenced.
- `never'
- Aliases are never dereferenced
-
- `always'
- Aliases are always dereferenced
-
- `search'
- Aliases are dereferenced when searching
-
- `find'
- Aliases are dereferenced when locating the base object
- for the search
-
- `timelimit'
- The timeout limit for the connection in seconds.
-
- `sizelimit'
- The maximum number of matches to return for searches
- performed on this connection.
-
- - Variable: ldap-verbose
- If non-`nil', LDAP operations will echo progress messages.
- Defaults to `nil'.

-The High-Level LDAP API
------------------------
-
-The following functions provide the most convenient interface to perform
-LDAP operations. All of them open a connection to a host, perform an
-operation (add/search/modify/delete) on one or several entries and
-cleanly close the connection thus insulating the user from all the
-details of the low-level interface such as LDAP Lisp objects *note The
-Low-Level LDAP API::.
-
- Note that `ldap-search' which used to be the name of the high-level
-search function in XEmacs 21.1 is now obsolete. For consistency in the
-naming as well as backward compatibility, that function now acts as a
-wrapper that calls either `ldap-search-basic' (low-level search
-function) or `ldap-search-entries' (high-level search function)
-according to the actual parameters. A direct call to one of these two
-functions is preferred since it is faster and unambiguous.

- - Command: ldap-search-entries filter &optional host attributes
- attrsonly withdn
- Perform an LDAP search. FILTER is the search filter *note Syntax
- of Search Filters:: HOST is the LDAP host on which to perform the
- search. ATTRIBUTES is the specific attributes to retrieve, `nil'
- means retrieve all. ATTRSONLY if non-`nil' retrieves the

- non-`nil' each entry in the result will be prepended with its
- distinguished name DN. Additional search parameters can be
- specified through `ldap-host-parameters-alist'. The function
- returns a list of matching entries. Each entry is itself an alist
- of attribute/value pairs optionally preceded by the DN of the
- entry according to the value of WITHDN.

-
- - Function: ldap-modify-entries entry-mods &optional host binddn passwd
- Modify entries of an LDAP directory. ENTRY_MODS is a list of
- entry modifications of the form `(DN MOD-SPEC1 MOD-SPEC2 ...)'
- where DN is the distinguished name of the entry to modify, the
- following are modification specifications. A modification
- specification is itself a list of the form `(MOD-OP ATTR VALUE1

+
+57.10 Flow Control
+==================
+
+This section attempts to answer the question "Why does XEmacs choose to
+use flow-control characters in its command character set?" For a
+second view on this issue, read the comments on flow control in the
+`emacs/INSTALL' file from the distribution; for help with Termcap
+entries and DEC terminal concentrators, see `emacs/etc/TERMS'.
+
+ At one time, most terminals did not need flow control, and none used
+`C-s' and `C-q' for flow control. Therefore, the choice of `C-s' and
+`C-q' as command characters was uncontroversial. XEmacs, for economy
+of keystrokes and portability, used nearly all the ASCII control
+characters, with mnemonic meanings when possible; thus, `C-s' for
+search and `C-q' for quote.
+
+ Later, some terminals were introduced which required these characters
+for flow control. They were not very good terminals for full-screen
+editing, so XEmacs maintainers did not pay attention. In later years,
+flow control with `C-s' and `C-q' became widespread among terminals,
+but by this time it was usually an option. And the majority of users,
+who can turn flow control off, were unwilling to switch to less
+mnemonic key bindings for the sake of flow control.
+
+ So which usage is "right", XEmacs's or that of some terminal and
+concentrator manufacturers? This question has no simple answer.
+
+ One reason why we are reluctant to cater to the problems caused by
+`C-s' and `C-q' is that they are gratuitous. There are other
+techniques (albeit less common in practice) for flow control that
+preserve transparency of the character stream. Note also that their use
+for flow control is not an official standard. Interestingly, on the
+model 33 teletype with a paper tape punch (which is very old), `C-s'
+and `C-q' were sent by the computer to turn the punch on and off!
+
+ As X servers and other window systems replace character-only
+terminals, this problem is gradually being cured. For the mean time,
+XEmacs provides a convenient way of enabling flow control if you want
+it: call the function `enable-flow-control'.
+
+ -- Command: enable-flow-control &optional argument
+ This function enables use of `C-s' and `C-q' for output flow
+ control, and provides the characters `C-\' and `C-^' as aliases
+ for them using `keyboard-translate-table' (*note Translating
+ Input::).
+
+ With optional argument ARGUMENT (interactively the prefix
+ argument), enable flow control mode if ARGUMENT is positive; else
+ disable it.
+
+ You can use the function `enable-flow-control-on' in your `.emacs'
+file to enable flow control automatically on certain terminal types.
+
+ -- Function: enable-flow-control-on &rest termtypes
+ This function enables flow control, and the aliases `C-\' and
+ `C-^', if the terminal type is one of TERMTYPES. For example:
+
+ (enable-flow-control-on "vt200" "vt300" "vt101" "vt131")
+
+ Here is how `enable-flow-control' does its job:
+
+ 1. It sets CBREAK mode for terminal input, and tells the operating
+ system to handle flow control, with `(set-input-mode nil t)'.
+
+ 2. It sets up `keyboard-translate-table' to translate `C-\' and `C-^'
+ into `C-s' and `C-q'. Except at its very lowest level, XEmacs
+ never knows that the characters typed were anything but `C-s' and
+ `C-q', so you can in effect type them as `C-\' and `C-^' even when
+ they are input for other commands. *Note Translating Input::.
+
+ If the terminal is the source of the flow control characters, then
+once you enable kernel flow control handling, you probably can make do
+with less padding than normal for that terminal. You can reduce the
+amount of padding by customizing the Termcap entry. You can also
+reduce it by setting `baud-rate' to a smaller value so that XEmacs uses
+a smaller speed when calculating the padding needed. *Note Terminal
+Output::.
+
+\1f
+File: lispref.info, Node: Batch Mode, Prev: Flow Control, Up: System Interface
+
+57.11 Batch Mode
+================
+
+The command line option `-batch' causes XEmacs to run noninteractively.
+In this mode, XEmacs does not read commands from the terminal, it does
+not alter the terminal modes, and it does not expect to be outputting
+to an erasable screen. The idea is that you specify Lisp programs to
+run; when they are finished, XEmacs should exit. The way to specify
+the programs to run is with `-l FILE', which loads the library named
+FILE, and `-f FUNCTION', which calls FUNCTION with no arguments.
+
+ Any Lisp program output that would normally go to the echo area,
+either using `message' or using `prin1', etc., with `t' as the stream,
+goes instead to XEmacs's standard error descriptor when in batch mode.
+Thus, XEmacs behaves much like a noninteractive application program.
+(The echo area output that XEmacs itself normally generates, such as
+command echoing, is suppressed entirely.)
+
+ -- Function: noninteractive
+ This function returns non-`nil' when XEmacs is running in batch
+ mode.
+
+ -- Variable: noninteractive
+ This variable is non-`nil' when XEmacs is running in batch mode.
+ Setting this variable to `nil', however, will not change whether
+ XEmacs is running in batch mode, and will not change the return
+ value of the `noninteractive' function.

+58 Functions Specific to the X Window System
+********************************************
+
+XEmacs provides the concept of "devices", which generalizes connections
+to an X server, a TTY device, etc. Most information about an X server
+that XEmacs is connected to can be determined through general console
+and device functions. *Note Consoles and Devices::. However, there
+are some features of the X Window System that do not generalize well,
+and they are covered specially here.
+
+* Menu:
+
+* X Selections:: Transferring text to and from other X clients.
+* X Server:: Information about the X server connected to
+ a particular device.
+* X Miscellaneous:: Other X-specific functions and variables.
+
+\1f
+File: lispref.info, Node: X Selections, Next: X Server, Up: X-Windows
+
+58.1 X Selections
+=================
+
+The X server records a set of "selections" which permit transfer of
+data between application programs. The various selections are
+distinguished by "selection types", represented in XEmacs by symbols.
+X clients including XEmacs can read or set the selection for any given
+type.
+
+ -- Function: x-own-selection data &optional type
+ This function sets a "selection" in the X server. It takes two
+ arguments: a value, DATA, and the selection type TYPE to assign it
+ to. DATA may be a string, a cons of two markers, or an extent.
+ In the latter cases, the selection is considered to be the text
+ between the markers, or between the extent's endpoints.
+
+ Each possible TYPE has its own selection value, which changes
+ independently. The usual values of TYPE are `PRIMARY' and
+ `SECONDARY'; these are symbols with upper-case names, in accord
+ with X Windows conventions. The default is `PRIMARY'.
+
+ (In FSF Emacs, this function is called `x-set-selection' and takes
+ different arguments.)
+
+ -- Function: x-get-selection
+ This function accesses selections set up by XEmacs or by other X
+ clients. It returns the value of the current primary selection.
+
+ -- Function: x-disown-selection &optional secondary-p
+ Assuming we own the selection, this function disowns it. If
+ SECONDARY-P is non-`nil', the secondary selection instead of the
+ primary selection is discarded.
+
+ The X server also has a set of numbered "cut buffers" which can
+store text or other data being moved between applications. Cut buffers
+are considered obsolete, but XEmacs supports them for the sake of X
+clients that still use them.
+
+ -- Function: x-get-cutbuffer &optional n
+ This function returns the contents of cut buffer number N. (This
+ function is called `x-get-cut-buffer' in FSF Emacs.)
+
+ -- Function: x-store-cutbuffer string &optional push
+ This function stores STRING into the first cut buffer (cut buffer
+ 0).
+
+ Normally, the contents of the first cut buffer are simply replaced
+ by STRING. However, if optional argument PUSH is non-`nil', the
+ cut buffers are rotated. This means that the previous value of
+ the first cut buffer moves to the second cut buffer, and the
+ second to the third, and so on, moving the other values down
+ through the series of cut buffers, kill-ring-style. There are 8
+ cut buffers altogether.
+
+ Cut buffers are considered obsolete; you should use selections
+ instead.
+
+ This function has no effect if support for cut buffers was not
+ compiled in.
+
+ This function is called `x-set-cut-buffer' in FSF Emacs.

+
+58.2.1 Resources
+----------------
+
+ -- Function: default-x-device
+ This function return the default X device for resourcing. This is
+ the first-created X device that still exists.
+
+ -- Function: x-get-resource name class type &optional locale device
+ noerror
+ This function retrieves a resource value from the X resource
+ manager.
+
+ * The first arg is the name of the resource to retrieve, such as
+ `"font"'.
+
+ * The second arg is the class of the resource to retrieve, like
+ `"Font"'.
+
+ * The third arg should be one of the symbols `string',
+ `integer', `natnum', or `boolean', specifying the type of
+ object that the database is searched for.
+
+ * The fourth arg is the locale to search for the resources on,
+ and can currently be a buffer, a frame, a device, or the
+ symbol `global'. If omitted, it defaults to `global'.
+
+ * The fifth arg is the device to search for the resources on.
+ (The resource database for a particular device is constructed
+ by combining non-device- specific resources such any
+ command-line resources specified and any app-defaults files
+ found [or the fallback resources supplied by XEmacs, if no
+ app-defaults file is found] with device-specific resources
+ such as those supplied using `xrdb'.) If omitted, it defaults
+ to the device of LOCALE, if a device can be derived (i.e. if
+ LOCALE is a frame or device), and otherwise defaults to the
+ value of `default-x-device'.
+
+ * The sixth arg NOERROR, if non-`nil', means do not signal an
+ error if a bogus resource specification was retrieved (e.g.
+ if a non-integer was given when an integer was requested).
+ In this case, a warning is issued instead.
+
+ The resource names passed to this function are looked up relative
+ to the locale.
+
+ If you want to search for a subresource, you just need to specify
+ the resource levels in NAME and CLASS. For example, NAME could be
+ `"modeline.attributeFont"', and CLASS `"Face.AttributeFont"'.
+
+ Specifically,
+
+ 1. If LOCALE is a buffer, a call
+
+ `(x-get-resource "foreground" "Foreground" 'string SOME-BUFFER)'
+
+ is an interface to a C call something like
+
+ `XrmGetResource (db, "xemacs.buffer.BUFFER-NAME.foreground",
+ "Emacs.EmacsLocaleType.EmacsBuffer.Foreground",
+ "String");'
+
+ 2. If LOCALE is a frame, a call
+
+ `(x-get-resource "foreground" "Foreground" 'string SOME-FRAME)'
+
+ is an interface to a C call something like
+
+ `XrmGetResource (db, "xemacs.frame.FRAME-NAME.foreground",
+ "Emacs.EmacsLocaleType.EmacsFrame.Foreground",
+ "String");'
+
+ 3. If LOCALE is a device, a call
+
+ `(x-get-resource "foreground" "Foreground" 'string SOME-DEVICE)'
+
+ is an interface to a C call something like
+
+ `XrmGetResource (db, "xemacs.device.DEVICE-NAME.foreground",
+ "Emacs.EmacsLocaleType.EmacsDevice.Foreground",
+ "String");'
+
+ 4. If LOCALE is the symbol `global', a call
+
+ `(x-get-resource "foreground" "Foreground" 'string 'global)'
+
+ is an interface to a C call something like
+
+ `XrmGetResource (db, "xemacs.foreground",
+ "Emacs.Foreground",
+ "String");'
+
+ Note that for `global', no prefix is added other than that of the
+ application itself; thus, you can use this locale to retrieve
+ arbitrary application resources, if you really want to.
+
+ The returned value of this function is `nil' if the queried
+ resource is not found. If TYPE is `string', a string is returned,
+ and if it is `integer', an integer is returned. If TYPE is
+ `boolean', then the returned value is the list `(t)' for true,
+ `(nil)' for false, and is `nil' to mean "unspecified".
+
+ -- Function: x-put-resource resource-line &optional device
+ This function adds a resource to the resource database for DEVICE.
+ RESOURCE-LINE specifies the resource to add and should be a
+ standard resource specification.
+
+ -- Variable: x-emacs-application-class
+ This variable holds The X application class of the XEmacs process.
+ This controls, among other things, the name of the "app-defaults"
+ file that XEmacs will use. For changes to this variable to take
+ effect, they must be made before the connection to the X server is
+ initialized, that is, this variable may only be changed before
+ XEmacs is dumped, or by setting it in the file
+ `lisp/term/x-win.el'.
+
+ By default, this variable is `nil' at startup. When the connection
+ to the X server is first initialized, the X resource database will
+ be consulted and the value will be set according to whether any
+ resources are found for the application class "XEmacs".

+------------------------------
+
+This section describes functions and a variable that you can use to get
+information about the capabilities and origin of the X server
+corresponding to a particular device. The device argument is generally
+optional and defaults to the selected device.
+
+ -- Function: x-server-version &optional device
+ This function returns the list of version numbers of the X server
+ DEVICE is on. The returned value is a list of three integers: the
+ major and minor version numbers of the X protocol in use, and the
+ vendor-specific release number.
+
+ -- Function: x-server-vendor &optional device
+ This function returns the vendor supporting the X server DEVICE is
+ on.
+
+ -- Function: x-display-visual-class &optional device
+ This function returns the visual class of the display DEVICE is
+ on. The value is one of the symbols `static-gray', `gray-scale',
+ `static-color', `pseudo-color', `true-color', and `direct-color'.
+ (Note that this is different from previous versions of XEmacs,

+58.2.3 Restricting Access to the Server by Other Apps
+-----------------------------------------------------
+
+ -- Function: x-grab-keyboard &optional device
+ This function grabs the keyboard on the given device (defaulting
+ to the selected one). So long as the keyboard is grabbed, all
+ keyboard events will be delivered to XEmacs--it is not possible
+ for other X clients to eavesdrop on them. Ungrab the keyboard
+ with `x-ungrab-keyboard' (use an `unwind-protect'). Returns `t'
+ if the grab was successful; `nil' otherwise.
+
+ -- Function: x-ungrab-keyboard &optional device
+ This function releases a keyboard grab made with `x-grab-keyboard'.
+
+ -- Function: x-grab-pointer &optional device cursor ignore-keyboard
+ This function grabs the pointer and restricts it to its current
+ window. If optional DEVICE argument is `nil', the selected device
+ will be used. If optional CURSOR argument is non-`nil', change
+ the pointer shape to that until `x-ungrab-pointer' is called (it
+ should be an object returned by the `make-cursor' function). If
+ the second optional argument IGNORE-KEYBOARD is non-`nil', ignore
+ all keyboard events during the grab. Returns `t' if the grab is
+ successful, `nil' otherwise.
+
+ -- Function: x-ungrab-pointer &optional device
+ This function releases a pointer grab made with `x-grab-pointer'.
+ If optional first arg DEVICE is `nil' the selected device is used.

+58.3 Miscellaneous X Functions and Variables
+============================================
+
+ -- Variable: x-bitmap-file-path
+ This variable holds a list of the directories in which X bitmap
+ files may be found. If `nil', this is initialized from the
+ `"*bitmapFilePath"' resource. This is used by the
+ `make-image-instance' function (however, note that if the
+ environment variable `XBMLANGPATH' is set, it is consulted first).
+
+ -- Variable: x-library-search-path
+ This variable holds the search path used by `read-color' to find
+ `rgb.txt'.
+
+ -- Function: x-valid-keysym-name-p keysym
+ This function returns true if KEYSYM names a keysym that the X
+ library knows about. Valid keysyms are listed in the files
+ `/usr/include/X11/keysymdef.h' and in `/usr/lib/X11/XKeysymDB', or
+ whatever the equivalents are on your system.
+
+ -- Function: x-window-id &optional frame
+ This function returns the ID of the X11 window. This gives us a
+ chance to manipulate the Emacs window from within a different
+ program. Since the ID is an unsigned long, we return it as a
+ string.
+
+ -- Variable: x-allow-sendevents
+ If non-`nil', synthetic events are allowed. `nil' means they are
+ ignored. Beware: allowing XEmacs to process SendEvents opens a
+ big security hole.
+
+ -- Function: x-debug-mode arg &optional device
+ With a true arg, make the connection to the X server synchronous.
+ With false, make it asynchronous. Synchronous connections are
+ much slower, but are useful for debugging. (If you get X errors,
+ make the connection synchronous, and use a debugger to set a
+ breakpoint on `x_error_handler'. Your backtrace of the C stack
+ will now be useful. In asynchronous mode, the stack above
+ `x_error_handler' isn't helpful because of buffering.) If DEVICE
+ is not specified, the selected device is assumed.
+
+ Calling this function is the same as calling the C function
+ `XSynchronize', or starting the program with the `-sync' command
+ line argument.
+
+ -- Variable: x-debug-events
+ If non-zero, debug information about events that XEmacs sees is
+ displayed. Information is displayed on stderr. Currently defined
+ values are:
+
+ * 1 == non-verbose output
+
+ * 2 == verbose output

+
+59.1 XEmacs ToolTalk API Summary
+================================
+
+The XEmacs Lisp interface to ToolTalk is similar, at least in spirit,
+to the standard C ToolTalk API. Only the message and pattern parts of
+the API are supported at present; more of the API could be added if
+needed. The Lisp interface departs from the C API in a few ways:
+
+ * ToolTalk is initialized automatically at XEmacs startup-time.
+ Messages can only be sent other ToolTalk applications connected to
+ the same X11 server that XEmacs is running on.
+
+ * There are fewer entry points; polymorphic functions with keyword
+ arguments are used instead.
+
+ * The callback interface is simpler and marginally less functional.
+ A single callback may be associated with a message or a pattern;
+ the callback is specified with a Lisp symbol (the symbol should
+ have a function binding).
+
+ * The session attribute for messages and patterns is always
+ initialized to the default session.
+
+ * Anywhere a ToolTalk enum constant, e.g. `TT_SESSION', is valid, one
+ can substitute the corresponding symbol, e.g. `'TT_SESSION'. This
+ simplifies building lists that represent messages and patterns.

+59.2.2 Elisp Interface for Sending Messages
+-------------------------------------------
+
+ -- Function: make-tooltalk-message attributes
+ Create a ToolTalk message and initialize its attributes. The
+ value of ATTRIBUTES must be a list of alternating keyword/values,
+ where keywords are symbols that name valid message attributes.
+ For example:
+
+ (make-tooltalk-message
+ '(class TT_NOTICE
+ scope TT_SESSION
+ address TT_PROCEDURE
+ op "do-something"
+ args ("arg1" 12345 (TT_INOUT "arg3" "string"))))
+
+ Values must always be strings, integers, or symbols that represent
+ ToolTalk constants. Attribute names are the same as those
+ supported by `set-tooltalk-message-attribute', plus `args'.
+
+ The value of `args' should be a list of message arguments where
+ each message argument has the following form:
+
+ `(mode [value [type]])' or just `value'
+
+ Where MODE is one of `TT_IN', `TT_OUT', or `TT_INOUT' and TYPE is
+ a string. If TYPE isn't specified then `int' is used if VALUE is
+ a number; otherwise `string' is used. If TYPE is `string' then
+ VALUE is converted to a string (if it isn't a string already) with
+ `prin1-to-string'. If only a value is specified then MODE
+ defaults to `TT_IN'. If MODE is `TT_OUT' then VALUE and TYPE
+ don't need to be specified. You can find out more about the
+ semantics and uses of ToolTalk message arguments in chapter 4 of
+ the `ToolTalk Programmer's Guide'.
+
+
+ -- Function: send-tooltalk-message msg
+ Send the message on its way. Once the message has been sent it's
+ almost always a good idea to get rid of it with
+ `destroy-tooltalk-message'.
+
+
+ -- Function: return-tooltalk-message msg &optional mode
+ Send a reply to this message. The second argument can be `reply',
+ `reject' or `fail'; the default is `reply'. Before sending a
+ reply, all message arguments whose mode is `TT_INOUT' or `TT_OUT'
+ should have been filled in--see `set-tooltalk-message-attribute'.
+
+
+ -- Function: get-tooltalk-message-attribute msg attribute &optional
+ argn
+ Returns the indicated ToolTalk message attribute. Attributes are
+ identified by symbols with the same name (underscores and all) as
+ the suffix of the ToolTalk `tt_message_<attribute>' function that
+ extracts the value. String attribute values are copied and
+ enumerated type values (except disposition) are converted to
+ symbols; e.g. `TT_HANDLER' is `'TT_HANDLER', `uid' and `gid' are
+ represented by fixnums (small integers), `opnum' is converted to a
+ string, and `disposition' is converted to a fixnum. We convert
+ `opnum' (a C int) to a string (e.g. `123' => `"123"') because
+ there's no guarantee that opnums will fit within the range of
+ XEmacs Lisp integers.
+
+ [TBD] Use the `plist' attribute instead of C API `user' attribute
+ for user-defined message data. To retrieve the value of a message
+ property, specify the indicator for ARGN. For example, to get the
+ value of a property called `rflag', use
+
+ (get-tooltalk-message-attribute msg 'plist 'rflag)
+
+ To get the value of a message argument use one of the `arg_val'
+ (strings), `arg_ival' (integers), or `arg_bval' (strings with
+ embedded nulls), attributes. For example, to get the integer
+ value of the third argument:
+
+ (get-tooltalk-message-attribute msg 'arg_ival 2)
+
+ As you can see, argument numbers are zero-based. The type of each
+ arguments can be retrieved with the `arg_type' attribute; however
+ ToolTalk doesn't define any semantics for the string value of
+ `arg_type'. Conventionally `string' is used for strings and `int'
+ for 32 bit integers. Note that XEmacs Lisp stores the lengths of
+ strings explicitly (unlike C) so treating the value returned by
+ `arg_bval' like a string is fine.
+
+
+ -- Function: set-tooltalk-message-attribute value msg attribute
+ &optional argn
+ Initialize one ToolTalk message attribute.
+
+ Attribute names and values are the same as for
+ `get-tooltalk-message-attribute'. A property list is provided for
+ user data (instead of the `user' message attribute); see
+ `get-tooltalk-message-attribute'.
+
+ Callbacks are handled slightly differently than in the C ToolTalk
+ API. The value of CALLBACK should be the name of a function of one
+ argument. It will be called each time the state of the message
+ changes. This is usually used to notice when the message's state
+ has changed to `TT_HANDLED' (or `TT_FAILED'), so that reply
+ argument values can be used.
+
+ If one of the argument attributes is specified as `arg_val',
+ `arg_ival', or `arg_bval', then ARGN must be the number of an
+ already created argument. Arguments can be added to a message
+ with `add-tooltalk-message-arg'.
+
+
+ -- Function: add-tooltalk-message-arg msg mode type &optional value
+ Append one new argument to the message. MODE must be one of
+ `TT_IN', `TT_INOUT', or `TT_OUT', TYPE must be a string, and VALUE
+ can be a string or an integer. ToolTalk doesn't define any
+ semantics for TYPE, so only the participants in the protocol
+ you're using need to agree what types mean (if anything).
+ Conventionally `string' is used for strings and `int' for 32 bit
+ integers. Arguments can initialized by providing a value or with
+ `set-tooltalk-message-attribute'; the latter is necessary if you
+ want to initialize the argument with a string that can contain
+ embedded nulls (use `arg_bval').
+
+
+ -- Function: create-tooltalk-message &optional no-callback
+ Create a new ToolTalk message. The message's session attribute is
+ initialized to the default session. Other attributes can be
+ initialized with `set-tooltalk-message-attribute'.
+ `make-tooltalk-message' is the preferred way to create and
+ initialize a message.
+
+ Optional arg NO-CALLBACK says don't add a C-level callback at all.
+ Normally don't do that; just don't specify the Lisp callback when
+ calling `make-tooltalk-message'.
+
+
+ -- Function: destroy-tooltalk-message msg
+ Apply `tt_message_destroy' to the message. It's not necessary to
+ destroy messages after they've been processed by a message or
+ pattern callback, the Lisp/ToolTalk callback machinery does this
+ for you.

+------------------------------------
+
+Here's a simple example of a handler for a message that tells XEmacs to
+display a string in the mini-buffer area. The message operation is
+called `emacs-display-string'. Its first (0th) argument is the string
+to display.

+
+59.3.2 Elisp Interface for Receiving Messages
+---------------------------------------------
+
+ -- Function: make-tooltalk-pattern attributes
+ Create a ToolTalk pattern and initialize its attributes. The
+ value of attributes must be a list of alternating keyword/values,
+ where keywords are symbols that name valid pattern attributes or
+ lists of valid attributes. For example:
+
+ (make-tooltalk-pattern
+ '(category TT_OBSERVE
+ scope TT_SESSION
+ op ("operation1" "operation2")
+ args ("arg1" 12345 (TT_INOUT "arg3" "string"))))
+
+ Attribute names are the same as those supported by
+ `add-tooltalk-pattern-attribute', plus `'args'.
+
+ Values must always be strings, integers, or symbols that represent
+ ToolTalk constants or lists of same. When a list of values is
+ provided all of the list elements are added to the attribute. In
+ the example above, messages whose `op' attribute is `"operation1"'
+ or `"operation2"' would match the pattern.
+
+ The value of ARGS should be a list of pattern arguments where each
+ pattern argument has the following form:
+
+ `(mode [value [type]])' or just `value'
+
+ Where MODE is one of `TT_IN', `TT_OUT', or `TT_INOUT' and TYPE is
+ a string. If TYPE isn't specified then `int' is used if VALUE is
+ a number; otherwise `string' is used. If TYPE is `string' then
+ VALUE is converted to a string (if it isn't a string already) with
+ `prin1-to-string'. If only a value is specified then MODE
+ defaults to `TT_IN'. If MODE is `TT_OUT' then VALUE and TYPE
+ don't need to be specified. You can find out more about the
+ semantics and uses of ToolTalk pattern arguments in chapter 3 of
+ the `ToolTalk Programmer's Guide'.
+
+
+ -- Function: register-tooltalk-pattern pattern
+ XEmacs will begin receiving messages that match this pattern.
+
+ -- Function: unregister-tooltalk-pattern pattern
+ XEmacs will stop receiving messages that match this pattern.
+
+ -- Function: add-tooltalk-pattern-attribute value pattern indicator
+ Add one value to the indicated pattern attribute. The names of
+ attributes are the same as the ToolTalk accessors used to set them
+ less the `tooltalk_pattern_' prefix and the `_add' suffix. For
+ example, the name of the attribute for the
+ `tt_pattern_disposition_add' attribute is `disposition'. The
+ `category' attribute is handled specially, since a pattern can only
+ be a member of one category (`TT_OBSERVE' or `TT_HANDLE').
+
+ Callbacks are handled slightly differently than in the C ToolTalk
+ API. The value of CALLBACK should be the name of a function of one
+ argument. It will be called each time the pattern matches an
+ incoming message.
+
+ -- Function: add-tooltalk-pattern-arg pattern mode vtype &optional
+ value
+ Add one fully-specified argument to a ToolTalk pattern. MODE must
+ be one of `TT_IN', `TT_INOUT', or `TT_OUT'. VTYPE must be a
+ string. VALUE can be an integer, string or `nil'. If VALUE is an
+ integer then an integer argument (`tt_pattern_iarg_add') is added;
+ otherwise a string argument is added. At present there's no way
+ to add a binary data argument.
+
+
+ -- Function: create-tooltalk-pattern
+ Create a new ToolTalk pattern and initialize its session attribute
+ to be the default session.
+

+======================================
+
+LDAP support must be added to XEmacs at build time since it requires
+linking to an external LDAP client library. As of 21.2, XEmacs has been
+successfully built and tested with
+
+ * OpenLDAP 1.2 (`http://www.openldap.org/')
+
+ * University of Michigan's LDAP 3.3
+ (`http://www.umich.edu/~dirsvcs/ldap/')
+
+ * LDAP SDK 1.0 from Netscape Corp. (`http://developer.netscape.com/')
+
+ Other libraries conforming to RFC 1823 will probably work also but
+may require some minor tweaking at C level.
+
+ The standard XEmacs configure script auto-detects an installed LDAP
+library provided the library itself and the corresponding header files
+can be found in the library and include paths. A successful detection
+will be signalled in the final output of the configure script.

+
+XEmacs LDAP API consists of two layers: a low-level layer which tries
+to stay as close as possible to the C API (where practical) and a

+
+ The low-level API should be used directly for very specific purposes

+60.2.2 The High-Level LDAP API
+------------------------------
+
+The following functions provide the most convenient interface to perform
+LDAP operations. All of them open a connection to a host, perform an
+operation (add/search/modify/delete) on one or several entries and
+cleanly close the connection thus insulating the user from all the
+details of the low-level interface such as LDAP Lisp objects *note The
+Low-Level LDAP API::.
+
+ Note that `ldap-search' which used to be the name of the high-level
+search function in XEmacs 21.1 is now obsolete. For consistency in the
+naming as well as backward compatibility, that function now acts as a
+wrapper that calls either `ldap-search-basic' (low-level search
+function) or `ldap-search-entries' (high-level search function)
+according to the actual parameters. A direct call to one of these two
+functions is preferred since it is faster and unambiguous.
+
+ -- Command: ldap-search-entries filter &optional host attributes
+ attrsonly withdn
+ Perform an LDAP search. FILTER is the search filter *note Syntax
+ of Search Filters:: HOST is the LDAP host on which to perform the
+ search. ATTRIBUTES is the specific attributes to retrieve, `nil'
+ means retrieve all. ATTRSONLY if non-`nil' retrieves the
+ attributes only without their associated values. If WITHDN is
+ non-`nil' each entry in the result will be prepended with its
+ distinguished name DN. Additional search parameters can be
+ specified through `ldap-host-parameters-alist'. The function
+ returns a list of matching entries. Each entry is itself an alist
+ of attribute/value pairs optionally preceded by the DN of the
+ entry according to the value of WITHDN.
+
+ -- Function: ldap-add-entries entries &optional host binddn passwd
+ Add entries to an LDAP directory. ENTRIES is a list of entry
+ specifications of the form `(DN (ATTR . VALUE) (ATTR . VALUE) ...)'
+ where DN the distinguished name of an entry to add, the following
+ are cons cells containing attribute/value string pairs. HOST is
+ the LDAP host, defaulting to `ldap-default-host'. BINDDN is the
+ DN to bind as to the server. PASSWD is the corresponding password.
+
+ -- Function: ldap-modify-entries entry-mods &optional host binddn
+ passwd
+ Modify entries of an LDAP directory. ENTRY_MODS is a list of
+ entry modifications of the form `(DN MOD-SPEC1 MOD-SPEC2 ...)'
+ where DN is the distinguished name of the entry to modify, the
+ following are modification specifications. A modification
+ specification is itself a list of the form `(MOD-OP ATTR VALUE1
+ VALUE2 ...)' MOD-OP and ATTR are mandatory, VALUES are optional
+ depending on MOD-OP. MOD-OP is the type of modification, one of
+ the symbols `add', `delete' or `replace'. ATTR is the LDAP
+ attribute type to modify. HOST is the LDAP host, defaulting to
+ `ldap-default-host'. BINDDN is the DN to bind as to the server.
+ PASSWD is the corresponding password.
+
+ -- Function: ldap-delete-entries dn &optional host binddn passwd
+ Delete an entry from an LDAP directory. DN is the distinguished
+ name of an entry to delete or a list of those. HOST is the LDAP
+ host, defaulting to `ldap-default-host'. BINDDN is the DN to bind
+ as to the server. PASSWD is the corresponding password.

+------------------
CCL programs are called automatically during Emacs buffer I/O when the
external representation has a coding system type of `shift-jis',
Coding Systems::). You can also call CCL programs from other CCL
programs, and from Lisp using these functions:
- - Function: ccl-execute ccl-program status
+ -- Function: ccl-execute ccl-program status
Execute CCL-PROGRAM with registers initialized by STATUS.
CCL-PROGRAM is a vector of compiled CCL code created by
`ccl-compile'. It is an error for the program to try to execute a
side-effect) to contain the ending values for the corresponding
registers and IC.
- - Function: ccl-execute-on-string ccl-program status string &optional
+ -- Function: ccl-execute-on-string ccl-program status string &optional
continue
Execute CCL-PROGRAM with initial STATUS on STRING. CCL-PROGRAM is
a vector of compiled CCL code created by `ccl-compile'. STATUS
To call a CCL program from another CCL program, it must first be
registered:
- - Function: register-ccl-program name ccl-program
+ -- Function: register-ccl-program name ccl-program
Register NAME for CCL program CCL-PROGRAM in `ccl-program-table'.
CCL-PROGRAM should be the compiled form of a CCL program, or
`nil'. Return index number of the registered CCL program.
Information about the processor time used by the CCL interpreter can
be obtained using these functions:
- - Function: ccl-elapsed-time
+ -- Function: ccl-elapsed-time
Returns the elapsed processor time of the CCL interpreter as cons
of user and system time, as floating point numbers measured in
seconds. If only one overall value can be determined, the return
value will be a cons of that value and 0.
- - Function: ccl-reset-elapsed-time
+ -- Function: ccl-reset-elapsed-time
Resets the CCL interpreter's internal elapsed time registers.

+63.7.5 CCL Example
+------------------
+
+In this section, we describe the implementation of a trivial coding
+system to transform from the Web's URL encoding to XEmacs' internal
+coding. Many people will have been first exposed to URL encoding when
+they saw "%20" where they expected a space in a file's name on their
+local hard disk; this can happen when a browser saves a file from the
+web and doesn't encode the name, as passed from the server, properly.
+
+ URL encoding itself is underspecified with regard to encodings beyond
+ASCII. The relevant document, RFC 1738, explicitly doesn't give any
+information on how to encode non-ASCII characters, and the "obvious"
+way--use the %xx values for the octets of the eight bit MIME character
+set in which the page was served--breaks when a user types a character
+outside that character set. Best practice for web development is to
+serve all pages as UTF-8 and treat incoming form data as using that
+coding system. (Oh, and gamble that your clients won't ever want to
+type anything outside Unicode. But that's not so much of a gamble with
+today's client operating systems.) We don't treat non-ASCII in this
+example, as dealing with `(read-multibyte-character ...)' and errors
+therewith would make it much harder to understand.
+
+ Since CCL isn't a very rich language, we move much of the logic that
+would ordinarily be computed from operations like `(member ..)', `(and
+...)' and `(or ...)' into tables, from which register values are read
+and written, and on which `if' statements are predicated. Much more of
+the implementation of this coding system is occupied with constructing
+these tables--in normal Emacs Lisp--than it is with actual CCL code.
+
+ All the `defvar' statements we deal with in the next few sections
+are surrounded by a `(eval-and-compile ...)', which means that the
+logic which initializes these variables executes at compile time, and if
+XEmacs loads the compiled version of the file, these variables are
+initialized as constants.

+63.7.5.1 Four bits to ASCII
+...........................
+
+The first `defvar' is for `url-coding-high-order-nybble-as-ascii', a
+256-entry table that maps from an octet's value to the ASCII encoding
+for the hex value of its most significant four bits. That might sound
+complex, but it isn't; for decimal 65, hex value `#x41', the entry in
+the table is the ASCII encoding of `4'. For decimal 122, ASCII `z',
+hex value `#x7a', `(elt url-coding-high-order-nybble-as-ascii #x7a)'
+after this file is loaded gives the ASCII encoding of 7.
+
+ (defvar url-coding-high-order-nybble-as-ascii
+ (let ((val (make-vector 256 0))
+ (i 0))
+ (while (< i (length val))
+ (aset val i (char-to-int (aref (format "%02X" i) 0)))
+ (setq i (1+ i)))
+ val)
+ "Table to find an ASCII version of an octet's most significant 4 bits.")
+
+ The next table, `url-coding-low-order-nybble-as-ascii' is almost the
+same thing, but this time it has a map for the hex encoding of the
+low-order four bits. So the sixty-fifth entry (offset `#x41') is the
+ASCII encoding of `1', the hundred-and-twenty-second (offset `#x7a') is
+the ASCII encoding of `A'.
+
+ (defvar url-coding-low-order-nybble-as-ascii
+ (let ((val (make-vector 256 0))
+ (i 0))
+ (while (< i (length val))
+ (aset val i (char-to-int (aref (format "%02X" i) 1)))
+ (setq i (1+ i)))

+
+63.7.5.2 URI Encoding constants
+...............................
+
+Next, we have a couple of variables that make the CCL code more
+readable. The first is the ASCII encoding of the percentage sign; this
+character is used as an escape code, to start the encoding of a
+non-printable character. For historical reasons, URL encoding allows
+the space character to be encoded as a plus sign-it does make typing
+URLs like `http://google.com/search?q=XEmacs+home+page' easier-and as
+such, we have to check when decoding for this value, and map it to the
+space character. When doing this in CCL, we use the
+`url-coding-escaped-space-code' variable.
+
+ (defvar url-coding-escape-character-code (char-to-int ?%)
+ "The code point for the percentage sign, in ASCII.")
+
+ (defvar url-coding-escaped-space-code (char-to-int ?+)

+
+63.7.5.3 Numeric to ASCII-hexadecimal conversion
+................................................
+
+Now, we have a couple of utility tables that wouldn't be necessary in a
+more expressive programming language than is CCL. The first is sixteen
+in length, and maps a hexadecimal number to the ASCII encoding of that
+number; so zero maps to ASCII `0', ten maps to ASCII `A.' The second
+does the reverse; that is, it maps an ASCII character to its value when
+interpreted as a hexadecimal digit. ('A' => 10, 'c' => 12, '2' => 2, as
+a few examples.)
+
+ (defvar url-coding-hex-digit-table
+ (let ((i 0)
+ (val (make-vector 16 0)))
+ (while (< i 16)
+ (aset val i (char-to-int (aref (format "%X" i) 0)))
+ (setq i (1+ i)))

+ (defvar url-coding-latin-1-as-hex-table
+ (let ((val (make-vector 256 0))
+ (i 0))
+ (while (< i (length val))
+ ;; Get a hex val for this ASCII character.
+ (aset val i (string-to-int (format "%c" i) 16))

+
+63.7.5.4 Characters to be preserved
+...................................
+
+And finally, the last of these tables. URL encoding says that
+alphanumeric characters, the underscore, hyphen and the full stop (1)
+retain their ASCII encoding, and don't undergo transformation.
+`url-coding-should-preserve-table' is an array in which the entries are
+one if the corresponding ASCII character should be left as-is, and zero
+if they should be transformed. So the entries for all the control and
+most of the punctuation charcters are zero. Lisp programmers will
+observe that this initialization is particularly inefficient, but
+they'll also be aware that this is a long way from an inner loop where
+every nanosecond counts.

+63.7.5.5 The program to decode to internal format
+.................................................
+
+After the almost interminable tables, we get to the CCL. The first CCL
+program, `ccl-decode-urlcoding' decodes from the URL coding to our
+internal format; since this version of CCL doesn't have support for
+error checking on the input, we don't do any verification on it.
+
+ The buffer magnification-approximate ratio of the size of the output
+buffer to the size of the input buffer-is declared as one, because
+fractional values aren't allowed. (Since all those %20's will map to `
+', the length of the output text will be less than that of the input
+text.)
+
+ So, first we read an octet from the input buffer into register `r0',
+to set up the loop. Next, we start the loop, with a `(loop ...)'
+statement, and we check if the value in `r0' is a percentage sign.
+(Note the comma before `url-coding-escape-character-code'; since CCL is
+a Lisp macro language, we can break out of the macro evaluation with a
+comman, and as such, "`,url-coding-escape-character-code'" will be
+evaluated as a literal `37.')
+
+ If it is a percentage sign, we read the next two octets into `r2'
+and `r3', and convert them into their hexadecimal numeric values, using
+the `url-coding-latin-1-as-hex-table' array declared above. (But
+again, it'll be interpreted as a literal array.) We then left shift
+the first by four bits, mask the two together, and write the result to
+the output buffer.
+
+ If it isn't a percentage sign, and it is a `+' sign, we write a
+space-hexadecimal 20-to the output buffer.
+
+ If none of those things are true, we pass the octet to the output
+buffer untransformed. (This could be a place to put error checking, in
+a more expressive language.) We then read one more octet from the input
+buffer, and move to the next iteration of the loop.
+
+ (define-ccl-program ccl-decode-urlcoding

+...................................................
+
+Next, we see the CCL program to encode ASCII text as URL coded text.
+Here, the buffer magnification is specified as three, to account for ` '
+mapping to %20, etc. As before, we read an octet from the input into
+`r0', and move into the body of the loop. Next, we check if we should
+preserve the value of this octet, by reading from offset `r0' in the
+`url-coding-should-preserve-table' into `r1'. Then we have an `if'
+statement predicated on the value in `r1'; for the true branch, we
+write the input octet directly. For the false branch, we write a
+percentage sign, the ASCII encoding of the high four bits in hex, and
+then the ASCII encoding of the low four bits in hex.
+
+ We then read an octet from the input into `r0', and repeat the loop.
+
+ (define-ccl-program ccl-encode-urlcoding

+
+To actually create the coding system, we call `make-coding-system'.
+The first argument is the symbol that is to be the name of the coding
+system, in our case `url-coding'. The second specifies that the coding
+system is to be of type `ccl'--there are several other coding system
+types available, including, see the documentation for
+`make-coding-system' for the full list. Then there's a documentation
+string describing the wherefore and caveats of the coding system, and
+the final argument is a property list giving information about the CCL
+programs and the coding system's mnemonic.

This function returns a new category table which is a copy of
CATEGORY-TABLE, which defaults to the standard category table.
- - Function: set-category-table category-table &optional buffer
+ -- Function: set-category-table category-table &optional buffer
This function selects CATEGORY-TABLE as the new category table for
BUFFER. BUFFER defaults to the current buffer if omitted.
- - Function: category-designator-p object

This function returns `t' if OBJECT is a category designator (a
char in the range `' '' to `'~'').
- - Function: category-table-value-p object
+ -- Function: category-table-value-p object
This function returns `t' if OBJECT is a category table value.
Valid values are `nil' or a bit vector of size 95.

XEmacs Lisp uses two kinds of storage for user-created Lisp objects:
"normal storage" and "pure storage". Normal storage is where all the
you try to preload additional libraries or add features to the standard
ones.

very close to the total amount of pure storage available--if it
were not, we would preallocate less.
- - Variable: purify-flag

This will create a sub-menu Management under the File menu. When
you select the submenu Management, it will contain three submenus:
Copy File, Delete File and Rename File.

You can think of the change log as a conceptual "undo list" which
explains how earlier versions were different from the current version.

Here are some simple examples of change log entries, starting with the
header line that says who made the change and when, followed by
and GCC.)

An application program that is going to use termcap must first look up
the description of the terminal type in use. This is done by calling
#else
#define term_buffer 0

init_terminal_data ()
{
char *termtype = getenv ("TERM");
int success;

if (termtype == 0)

-The Template for a Definition
-=============================
-
-The `@deffn' command is used for definitions of entities that resemble
-functions. To write a definition using the `@deffn' command, write the
-`@deffn' command at the beginning of a line and follow it on the same
-line by the category of the entity, the name of the entity itself, and
-its arguments (if any). Then write the body of the definition on
-succeeding lines. (You may embed examples in the body.) Finally, end
-the definition with an `@end deffn' command written on a line of its
-own. (The other definition commands follow the same format.)
-
- The template for a definition looks like this:
-
- @deffn CATEGORY NAME ARGUMENTS...
- BODY-OF-DEFINITION
- @end deffn
-
-For example,
-
- @deffn Command forward-word count
- This command moves point forward @var{count} words
- (or backward if @var{count} is negative). ...
- @end deffn
-
-produces
-
- - Command: forward-word count
- This function moves point forward COUNT words (or backward if
- COUNT is negative). ...
-
- Capitalize the category name like a title. If the name of the
-category contains spaces, as in the phrase `Interactive Command', write
-braces around it. For example:
-
- @deffn {Interactive Command} isearch-forward
- ...
- @end deffn
-
-Otherwise, the second word will be mistaken for the name of the entity.
-
- Some of the definition commands are more general than others. The
-`@deffn' command, for example, is the general definition command for
-functions and the like--for entities that may take arguments. When you
-use this command, you specify the category to which the entity belongs.
-The `@deffn' command possesses three predefined, specialized
-variations, `@defun', `@defmac', and `@defspec', that specify the
-category for you: "Function", "Macro", and "Special Form" respectively.
-(In Lisp, a special form is an entity much like a function.) The
-`@defvr' command also is accompanied by several predefined, specialized
-variations for describing particular kinds of variables.
-
- The template for a specialized definition, such as `@defun', is
-similar to the template for a generalized definition, except that you
-do not need to specify the category:
-
- @defun NAME ARGUMENTS...
- BODY-OF-DEFINITION
- @end defun
-
-Thus,

- @defun buffer-end flag
- This function returns @code{(point-min)} if @var{flag}

-Learning XEmacs is a lifelong activity. Even people who have used Emacs
-for years keep discovering new features. Therefore this document cannot
-be complete. Instead it is aimed at the person who is either
-considering XEmacs for their own use, or has just obtained it and is
-wondering what to do next. It is also useful as a reference to
-available resources.
-
- The previous maintainer of the FAQ was Anthony Rossini
-<rossini@biostat.washington.edu>, who started it, after getting tired
-of hearing JWZ complain about repeatedly having to answer questions.
-Ben Wing <ben@xemacs.org> and Chuck Thompson <cthomp@xemacs.org>, the
-principal authors of XEmacs, then took over and Ben did a massive
-update reorganizing the whole thing. At which point Anthony took back
-over, but then had to give it up again. Some of the other contributors
-to this FAQ are listed later in this document.
-
- The previous version was converted to hypertext format, and edited by
-Steven L. Baur <steve@xemacs.org>. It was converted back to texinfo by
-Hrvoje Niksic <hniksic@xemacs.org>. The FAQ was then maintained by
-Andreas Kaempf <andreas@sccon.com>, who passed it on to ChristianNyb/o.

-1.0: Introduction
-=================
-
-Q1.0.1: What is XEmacs?
------------------------
-
-XEmacs is a powerful, highly customizable open source text editor and
-application development system, with full GUI support. It is protected
-under the GNU Public License and related to other versions of Emacs, in
-particular GNU Emacs. Its emphasis is on modern graphical user
-interface support and an open software development model, similar to
-Linux. XEmacs has an active development community numbering in the
-hundreds (and thousands of active beta testers on top of this), and runs
-on all versions of MS Windows, on Linux, and on nearly every other
-version of Unix in existence. Support for XEmacs has been supplied by
-Sun Microsystems, University of Illinois, Lucid, ETL/Electrotechnical
-Laboratory, Amdahl Corporation, BeOpen, and others, as well as the
-unpaid time of a great number of individual developers.

-
-Q1.0.2: What is the current version of XEmacs?
-----------------------------------------------
-
-XEmacs versions 21.1.* are releases made from the current stable
-sources. XEmacs versions 21.2.* are releases made from the development
-sources. Check at `http://www.xemacs.org' for the current minor
-version.
-
- XEmacs 19.16 was the last release of v19, released in November, 1997,
-which was also the last version without international language support.

-
-The canonical source and binaries can be found via anonymous FTP at:
-
- `ftp://ftp.xemacs.org/pub/xemacs/'

-
-Q1.0.4: Why Another Version of Emacs?
--------------------------------------
-
-For a detailed description of the differences between GNU Emacs and
-XEmacs and a detailed history of XEmacs, check out the
- NEWS file (http://www.xemacs.org/About/XEmacsVsGNUemacs.html)
-
- However, here is a list of some of the reasons why we think you might
-consider using it:
-
- * It looks nicer.
-
- * The XEmacs maintainers are generally more receptive to suggestions
- than the GNU Emacs maintainers.
-
- * Many more bundled packages than GNU Emacs.
-
- * Binaries are available for many common operating systems.
-
- * Face support on TTY's.
-
- * A built-in toolbar.
-
- * Better Motif compliance.
-
- * Some internationalization support (including full MULE support, if
- compiled with it).
-
- * Variable-width fonts.
-
- * Variable-height lines.
-
- * Marginal annotations.
-
- * ToolTalk support.
-
- * XEmacs can be used as an Xt widget, and can be embedded within
- another application.
-
- * Horizontal and vertical scrollbars (using real toolkit scrollbars).
-
- * Better APIs (and performance) for attaching fonts, colors, and
- other properties to text.
-
- * The ability to embed arbitrary graphics in a buffer.
-
- * Completely compatible (at the C level) with the Xt-based toolkits.

-Q1.0.5: Why Haven't XEmacs and GNU Emacs Merged?
-------------------------------------------------
-
-There are currently irreconcilable differences in the views about
-technical, programming, design and organizational matters between RMS
-and the XEmacs development team which provide little hope for a merge to
-take place in the short-term future.
-
- If you have a comment to add regarding the merge, it is a good idea
-to avoid posting to the newsgroups, because of the very heated
-flamewars that often result. Mail your questions to
-<xemacs-beta@xemacs.org> and <bug-gnu-emacs@prep.ai.mit.edu>.

-
-Q1.0.6: Where can I get help?
------------------------------
-
-Probably the easiest way, if everything is installed, is to use Info, by
-pressing `C-h i', or looking for an Info item on the Help Menu. `M-x
-apropos' can be used to look for particular commands.
-
- For items not found in the manual, try reading this FAQ and reading
-the Usenet group comp.emacs.xemacs.
-
- If you choose to post to a newsgroup, *please use
-comp.emacs.xemacs*. Please do not post XEmacs related questions to
-gnu.emacs.help.
-
- If you cannot post or read Usenet news, there is a corresponding
-mailing list <xemacs-news@xemacs.org> which is available. It can be
-subscribed to via the Mailman Web interface or by sending mail to to
-<xemacs-news-request@xemacs.org> with `subscribe' in the body of the
-message. See also `http://www.xemacs.org/Lists/#xemacs-news'. To
-cancel a subscription, you may use the <xemacs-news-request@xemacs.org>

- XEmacs 21.5 (perhaps 21.4 also?) works on MacOS X, although it
-certainly will not feel very much like a Mac application as it has no
-Mac-specific code in it.
-
- There is also a port of XEmacs 19.14 that works on all recent
-versions of MacOS, from 8.1 through MacOS X, by Pitts Jarvis
-<pjarvis@ispchannel.com>. It runs in an equivalent of TTY mode only
-(one single Macintosh window, 25 colors), but has a large number of
-Mac-specific additions. It's available at

-1.3: Internationalization
-=========================
-
-Q1.3.1: What is the status of internationalization support aka MULE (including Asian language support?
-------------------------------------------------------------------------------------------------------
-
-Both the stable and development versions of XEmacs include
-internationalization support (aka MULE). MULE currently (21.4) works on
-UNIX and Linux systems. It is possible to build with MULE on Windows
-systems, but if you really need MULE on Windows, it is recommended that
-you build and use the development (21.5) version, and deal with the
-instability of the development tree. Binaries compiled without MULE
-support run faster than MULE capable XEmacsen.

-
-Q1.3.2: How can I help with internationalization?
--------------------------------------------------
-
-If you would like to help, you may want to join the
-<xemacs-mule@xemacs.org> mailing list. Especially needed are people
-who speak/write languages other than English, who are willing to use
-XEmacs/MULE regularly, and have some experience with Elisp.
-
- Translations of the TUTORIAL and man page are welcome, and XEmacs
-does support multilingual menus, but we have few current translations.

--------------------------------------------
-
-See question 3.5.7 (*note Q3.5.7::) in part 3 of this FAQ for some
-simple methods that also work in non-MULE builds of XEmacs (but only for
-one-octet coded character sets, and mostly for ISO 8859/1). Many of the
-methods available for Cyrillic (*note Q1.3.7::) work without MULE.
-MULE has more general capabilities. *Note Q1.3.5::.

- *Note Q3.2.7::, which covers display of non-ASCII characters.

-
-Q1.3.4: Can XEmacs messages come out in a different language?
--------------------------------------------------------------
-
-The message-catalog support was written but is badly bit-rotted. XEmacs
-20 and 21 did _not_ support it, and early releases of XEmacs 22 will
-not either.
-
- However, menubar localization _does_ work. To enable it, add to
-your `Emacs' file entries like this:
-
- Emacs*XlwMenu.resourceLabels: True
- Emacs*XlwMenu.file.labelString: Fichier
- Emacs*XlwMenu.openInOtherWindow.labelString: In anderem Fenster oeffnen
-
- The name of the resource is derived from the non-localized entry by
-removing punctuation and capitalizing as above.

-
-Q1.3.5: Please explain the various input methods in MULE/XEmacs
----------------------------------------------------------------
-
-Mule supports a wide variety of input methods. There are three basic
-classes: Lisp implementations, generic platform support, and library
-interfaces.
-
- _Lisp implementations_ include Quail, which provides table-driven
-input methods for almost all the character sets that Mule supports
-(including all of the ISO 8859 family, the Indic languages, Thai, and
-so on), and SKK, for Japanese. (SKK also supports an interface to an
-external "dictionary server" process.) Quail supports both typical
-"dead-key" methods (eg, in the "latin-1-prefix" method, `" a' produces
-ä, LATIN SMALL LETTER A WITH DIAERESIS), and the complex
-dictionary-based phonetic methods used for Asian ideographic languages
-like Chinese.
-
- Lisp implementations can be less powerful (but they are not
-perceptibly inefficient), and of course are not portable to non-Emacs
-applications. The incompatibility can be very annoying. On the other
-hand, they require no special platform support or external libraries,
-so if you can display the characters, Mule can input them for you and
-you can edit, anywhere.
-
- _Generic platform support_ is currently limited to the X Input
-Method (XIM) framework, although support for MSIME (for MS Windows) is
-planned, and IIIMF (Sun's Internet-Intranet Input Method Framework)
-support is extremely desirable. XIM is enabled at build time by use of
-the `--with-xim' flag to `configure'. For use of XIM, see your
-platform documentation. However, normally the input method you use is
-specified via the `LANG' and `XMODIFIERS' environment variables.
-
- Of course, input skills are portable across most applications.
-However, especially in modern GUI systems the habit of using bucky bits
-has fallen into sad disuse, and many XIM systems are poorly configured
-for use with Emacs. For example, the kinput2 input manager (a separate
-process providing an interface between Japanese dictionary servers such
-as Canna and Wnn, and the application) tends to gobble up keystrokes
-generating Meta characters. This means that to edit while using an XIM
-input method, you must toggle the input method off every time you want
-to use `M-f'. Your mileage may vary.
-
- _Library interfaces_ are most common for Japanese, although Wnn
-supports Chinese (traditional and simplified) and Korean. There are
-Chinese and Korean input servers available, but we do not know of any
-patches for XEmacs to use them directly. You can use them via
-IM-enabled terminals, by manipulating the terminal coding systems. We
-describe only the Japanese-oriented systems here. The advantage of
-these systems is that they are very powerful, and on platforms where
-they are available there is typically a wide range of applications that
-support them. Thus your input skills are portable across applications.
-
- Mule provides built-in interfaces to the following input methods:
-Wnn4, Wnn6, Canna, and SJ3. These can be configured at build time.
-There are patches available (no URL, sorry) to support the SKK server,
-as well. Wnn and SJ3 use the `egg' user interface. The interface for
-Canna is specialized to Canna.
-
- Wnn supports Japanese, Chinese and Korean. It is made by OMRON and
-Kyôto University. It is a powerful and complex system. Wnn4 is free
-and Wnn6 is not. Wnn uses grammatical hints and probability of word
-association, so in principle Wnn can be cleverer than other methods.
-
- Canna, made by NEC, supports only Japanese. It is a simple and
-powerful system. Canna uses only grammar, but its grammar and
-dictionary are quite sophisticated. So for standard modern Japanese,
-Canna seems cleverer than Wnn4. In addition, the UNIX version of Canna
-is free (now there is a Microsoft Windows version).
-
- SJ3, by Sony, supports only Japanese.
-
- Egg consists of following parts:
-
- 1. Input character Translation System (ITS) layer. It translates
- ASCII inputs to Kana/PinYin/Hangul characters.
-
- 2. Kana/PinYin/Hangul to Kanji transfer layer. The interface layer
- to network Kana-Kanji server (Wnn and Sj3).
-
- These input methods are modal. They have a raw (alphabet) mode, a
-phonetic input mode, and Kana-Kanji transfer mode. However there are
-mode-less input methods for Egg and Canna. `boiled-egg' is a mode-less
-input method running on Egg. For Canna, `canna.el' has a tiny
-boiled-egg-like command, `(canna-boil)', and there are some
-boiled-egg-like utilities.

-Q1.3.6: How do I portably code for MULE/XEmacs?
------------------------------------------------
-
-MULE has evolved rapidly over the last few years, and the original third
-party patch (for GNU Emacs 19), GNU Emacs 20+, and XEmacs 20+ have quite
-different implementations. The APIs also vary although recent versions
-of XEmacs have tended to converge to the GNU Emacs standard.
-
- MULE implementations are going to continue to evolve. Both GNU Emacs
-and XEmacs are working hard on Unicode support, which will involve new
-APIs and probably variations on old ones. For XEmacs 22, the old ISO
-2022-based system for recognizing encodings will be replaced by a much
-more flexible system, which should improve accuracy of automatic coding
-detections, but will also involve new APIs.
-
- MORIOKA Tomohiko <morioka@jaist.ac.jp> writes:
-
- The application implementor must write separate code for these mule
- variants. [Please don't hesitate to report these variants to us;
- they are not, strictly speaking, bugs, but they give third-party
- developers the same kind of creepy-crawly feeling. We'll do what
- we can. - Ed.]
-
- MULE and the next version of Emacs are similar but the symbols are
- very different--requiring separate code as well.
-
- Namely we must support 3 kinds of mule variants and 4 or 5 or 6
- kinds of emacs variants... (;_;) I'm shocked, so I wrote a wrapper
- package called `emu' to provide a common interface. [There is an
- XEmacs package of APEL which provides much more comprehensive
- coverage. Be careful, however; APEL has problems of its own. -
- Ed.]
-
- I have the following suggestions about dealing with mule variants:
-
- * `(featurep 'mule)' `t' on all mule variants
-
- * `(boundp 'MULE)' is `t' on only MULE. Maybe the next version
- of Emacs will not have this symbol.
-
- * MULE has a variable `mule-version'. Perhaps the next version
- of Emacs will have this variable as well.
-
- Following is a sample to distinguish mule variants:
-
- (if (featurep 'mule)
- (cond ((boundp 'MULE)
- ;; for original Mule
- )
- ((string-match "XEmacs" emacs-version)
- ;; for XEmacs with Mule
- )
- (t
- ;; for next version of Emacs
- ))
- ;; for old emacs variants

-Q1.3.8: Does XEmacs support Unicode?
-------------------------------------
-
-Partially, as an external encoding for files, processes, and terminals.
-It does not yet support Unicode fonts *Note Does XEmacs support Unicode
-Fonts?: Q1.3.9
-
- To get Unicode support, you need a Mule-enabled XEmacs. Install
-Mule-UCS from packages in the usual way. Put
-
- (require 'un-define)
- (set-coding-priority-list '(utf-8))
- (set-coding-category-system 'utf-8 'utf-8)
-
- in your init file to enable the UTF-8 coding system. You may wish to
-view the documentation of `set-coding-priority-list' if you find that
-files that are not UTF-8 are being mis-recognized as UTF-8.
-
- Install standard national fonts (not Unicode fonts) for all
-character sets you use. See *Note Q1.3.9::.
-
- Mule-UCS also supports 16-bit forms of Unicode (UTF-16). It does not
-support 31-bit forms of Unicode (UTF-32 or UCS-4).

-
-Q1.3.9: How does XEmacs display Unicode?
-----------------------------------------
-
-Mule doesn't have a Unicode charset internally, so there's nothing to
-bind a Unicode registry to. It would not be straightforward to create,
-either, because Unicode is not ISO 2022-compatible. You'd have to
-translate it to multiple 96x96 pages.
-
- This means that Mule-UCS uses ordinary national fonts for display.
-This is not really a problem, except for those languages that use the
-Unified Han characters. The problem here is that Mule-UCS maps from
-Unicode code points to national character sets in a deterministic way.
-By default, this means that Japanese fonts are tried first, then
-Chinese, then Korean. To change the priority ordering, use the command
-`un-define-change-charset-order'.
-
- It also means you can't use Unicode fonts directly, at least not
-without extreme hackery. You can run -nw with
-(set-terminal-coding-system 'utf-8) if you really want a Unicode font
-for some reason.
-
- Real Unicode support will be introduced in XEmacs 22.0.

-1.4: Getting Started, Backing up & Recovery
-===========================================
-
-Q1.4.1: What is an `init.el' or `.emacs' and is there a sample one?
--------------------------------------------------------------------
-
-The `init.el' or `.emacs' file is used to customize XEmacs to your
-tastes. Starting in 21.4, the preferred location for the init file is
-`~/.xemacs/init.el'; in previous versions, it was `~/.emacs'. 21.4
-still accepts the old location, but the first time you run it, it will
-ask to migrate your file to the new location. If you answer yes, the
-file will be moved, and a "compatibility" `.emacs' file will be placed
-in the old location so that you can still run older versions of XEmacs,
-and versions of GNU Emacs, which expect the old location. The `.emacs'
-file present is just a stub that loads the real file in
-`~/.xemacs/init.el'.
-
- No two init files are alike, nor are they expected to be alike, but
-that's the point. The XEmacs distribution contains an excellent starter
-example in the `etc/' directory called `sample.init.el' (starting in
-21.4) or `sample.emacs' in older versions. Copy this file from there
-to `~/.xemacs/init.el' (starting in 21.4) or `~/.emacs' in older
-versions, where `~' means your home directory, of course. Then edit it
-to suit.
-
- You may bring the `sample.init.el' or `sample.emacs' file into an
-XEmacs buffer from the menubar. (The menu entry for it is always under
-the `Help' menu, but its location under that has changed in various
-versions. Recently, look under the `Samples' submenu.) To determine
-the location of the `etc/' directory type the command `C-h v
-data-directory <RET>'.

-
-Q1.4.3: Any good tutorials around?
-----------------------------------
-
-There's the XEmacs tutorial available from the Help Menu under
-`Basics->Tutorials', or by typing `C-h t'. To check whether it's
-available in a non-english language, type `C-u C-h t TAB', type the
-first letters of your preferred language, then type <RET>.

-
-Q1.4.4: May I see an example of a useful XEmacs Lisp function?
---------------------------------------------------------------
-
-The following function does a little bit of everything useful. It does
-something with the prefix argument, it examines the text around the
-cursor, and it's interactive so it may be bound to a key. It inserts
-copies of the current word the cursor is sitting on at the cursor. If
-you give it a prefix argument: `C-u 3 M-x double-word' then it will
-insert 3 copies.
-
- (defun double-word (count)
- "Insert a copy of the current word underneath the cursor"
- (interactive "*p")
- (let (here there string)
- (save-excursion
- (forward-word -1)
- (setq here (point))
- (forward-word 1)
- (setq there (point))
- (setq string (buffer-substring here there)))
- (while (>= count 1)
- (insert string)
- (decf count))))
-
- The best way to see what is going on here is to let XEmacs tell you.
-Put the code into an XEmacs buffer, and do a `C-h f' with the cursor
-sitting just to the right of the function you want explained. Eg. move
-the cursor to the SPACE between `interactive' and `"*p"' and hit `C-h
-f' to see what the function `interactive' does. Doing this will tell
-you that the `*' requires a writable buffer, and `p' converts the
-prefix argument to a number, and `interactive' allows you to execute
-the command with `M-x'.

-
-Q1.4.5: And how do I bind it to a key?
---------------------------------------
-
-To bind to a key do:
-
- (global-set-key "\C-cd" 'double-word)
-
- Or interactively, `M-x global-set-key' and follow the prompts.

-
-Q1.4.6: What's the difference between a macro and a function?
--------------------------------------------------------------
-
-Quoting from the Lisp Reference (a.k.a "Lispref") Manual:
-
- "Macros" enable you to define new control constructs and other
-language features. A macro is defined much like a function, but instead
-of telling how to compute a value, it tells how to compute another Lisp
-expression which will in turn compute the value. We call this
-expression the "expansion" of the macro.
-
- Macros can do this because they operate on the unevaluated
-expressions for the arguments, not on the argument values as functions
-do. They can therefore construct an expansion containing these
-argument expressions or parts of them.
-
- Do not confuse the two terms with "keyboard macros", which are
-another matter, entirely. A keyboard macro is a key bound to several
-other keys. Refer to manual for details.

-2.0: Installation
-=================
-
-Q2.0.1: Running XEmacs without installing
------------------------------------------
-
-How can I just try XEmacs without installing it?
-
- XEmacs will run in place without requiring installation and copying
-of the Lisp directories, and without having to specify a special
-build-time flag. It's the copying of the Lisp directories that
-requires so much space. XEmacs is largely written in Lisp.
-
- A good method is to make a shell alias for xemacs:
-
- alias xemacs=/i/xemacs-20.2/src/xemacs
-
- (You will obviously use whatever directory you downloaded the source
-tree to instead of `/i/xemacs-20.2').
-
- This will let you run XEmacs without massive copying.
-
-\1f
-File: xemacs-faq.info, Node: Q2.0.2, Next: Q2.0.3, Prev: Q2.0.1, Up: Installation
-
-Q2.0.2: XEmacs is too big
--------------------------
-
-The space required by the installation directories can be reduced
-dramatically if desired. Gzip all the .el files. Remove all the
-packages you'll never want to use. Remove the TexInfo manuals. Remove
-the Info (and use just hardcopy versions of the manual). Remove most
-of the stuff in etc. Remove or gzip all the source code. Gzip or
-remove the C source code. Configure it so that copies are not made of
-the support lisp.
-
- These are all Emacs Lisp source code and bytecompiled object code.
-You may safely gzip everything named *.el here. You may remove any
-package you don't use. _Nothing bad will happen if you delete a package
-that you do not use_. You must be sure you do not use it though, so be
-conservative at first.
-
- Any package with the possible exceptions of xemacs-base, and EFS are
-candidates for removal. Ask yourself, _Do I ever want to use this
-package?_ If the answer is no, then it is a candidate for removal.
-
- First, gzip all the .el files. Then go about package by package and
-start gzipping the .elc files. Then run XEmacs and do whatever it is
-you normally do. If nothing bad happens, then remove the package. You
-can remove a package via the PUI interface (`M-x pui-list-packages',
-then press `d' to mark the packages you wish to delete, and then `x' to
-delete them.
-
- Another method is to do `M-x package-get-delete-package'.

-
-Q2.0.3: Compiling XEmacs with Netaudio.
----------------------------------------
-
-What is the best way to compile XEmacs with the netaudio system, since I
-have got the netaudio system compiled but installed at a weird place, I
-am not root. Also in the READMEs it does not say anything about
-compiling with the audioserver?
-
- You should only need to add some stuff to the configure command line.
-To tell it to compile in netaudio support: `--with-sound=both', or
-`--with-sound=nas' if you don't want native sound support for some
-reason.) To tell it where to find the netaudio includes and libraries:
-
- --site-libraries=WHATEVER
- --site-includes=WHATEVER
-
- Then (fingers crossed) it should compile and it will use netaudio if
-you have a server running corresponding to the X server. The netaudio
-server has to be there when XEmacs starts. If the netaudio server goes
-away and another is run, XEmacs should cope (fingers crossed, error
-handling in netaudio isn't perfect).
-
- BTW, netaudio has been renamed as it has a name clash with something
-else, so if you see references to NAS or Network Audio System, it's the
-same thing. It also might be found at
-`ftp://ftp.x.org/contrib/audio/nas/'.

-
- 1. Upgrade your libc to at least 5.2.16 (better is 5.2.18, 5.3.12, or
- 5.4.10).
-
- 2. Patch the XEmacs binary by replacing all occurrences of
- `_h_errno^@' with `h_errno^@^@'. Any version of Emacs will
- suffice. If you don't understand how to do this, don't do it.
-
- 3. Rebuild XEmacs yourself--any working ELF version of libc should be
- O.K.

-Q2.0.10: After I run configure I find a core dump, is something wrong?
-----------------------------------------------------------------------
-
-Not necessarily. If you have GNU sed 3.0 you should downgrade it to
-2.05. From the `README' at prep.ai.mit.edu:
-
- sed 3.0 has been withdrawn from distribution. It has major
- revisions, which mostly seem to be improvements; but it turns out
- to have bugs too which cause trouble in some common cases.
-
- Tom Lord won't be able to work fixing the bugs until May. So in
- the mean time, we've decided to withdraw sed 3.0 from distribution
- and make version 2.05 once again the recommended version.
-
- It has also been observed that the vfork test on Solaris will leave a
-core dump.

-Q2.0.11: XEmacs doesn't resolve hostnames.
-------------------------------------------
-
-This is the result of a long-standing problem with SunOS and the fact
-that stock SunOS systems do not ship with DNS resolver code in libc.
-
- Christopher Davis <ckd@loiosh.kei.com> writes:
-
- That's correct [The SunOS 4.1.3 precompiled binaries don't do name
- lookup]. Since Sun figured that everyone used NIS to do name
- lookups (that DNS thing was apparently only a passing fad,
- right?), the stock SunOS 4.x systems don't have DNS-based name
- lookups in libc.
-
- This is also why Netscape ships two binaries for SunOS 4.1.x.
-
- The best solution is to compile it yourself; the configure script
- will check to see if you've put DNS in the shared libc and will
- then proceed to link against the DNS resolver library code.

-Q2.0.12: Why can't I strip XEmacs?
-----------------------------------
-
-Richard Cognot <cognot@fronsac.ensg.u-nancy.fr> writes:
-
- Because of the way XEmacs (and every other Emacsen, AFAIK) is
- built. The link gives you a bare-boned emacs (called temacs).
- temacs is then run, preloading some of the lisp files. The result
- is then dumped into a new executable, named xemacs, which will
- contain all of the preloaded lisp functions and data.
-
- Now, during the dump itself, the executable (code+data+symbols) is
- written on disk using a special unexec() function. This function is
- obviously heavily system dependent. And on some systems, it leads
- to an executable which, although valid, cannot be stripped without
- damage. If memory serves, this is especially the case for AIX
- binaries. On other architectures it might work OK.
-
- The Right Way to strip the emacs binary is to strip temacs prior to
- dumping xemacs. This will always work, although you can do that
- only if you install from sources (as temacs is `not' part of the
- binary kits).

-Q2.0.14: How do I figure out which packages to install?

-
-Many people really liked the old way that packages were bundled and do

-once like you used to with old XEmacs versions. Download the file
-
- `xemacs-sumo.tar.gz'
-
- For an XEmacs compiled with Mule you also need
-
- `xemacs-mule-sumo.tar.gz'
-
- from the `packages' directory on your XEmacs mirror archive. N.B.
-They are called 'Sumo Tarballs' for good reason. They are currently
-about 15MB and 2.3MB (gzipped) respectively.
-
- Install them by
-
- `cd $prefix/lib/xemacs ; gunzip -c <tarballname> | tar xf -'
-
- See README.packages for more detailed installation instructions.
-
- As the Sumo tarballs are not regenerated as often as the individual
-packages, it is recommended that you use the automatic package tools
-afterwards to pick up any recent updates.

-2.1: Trouble Shooting
-=====================
-
-Q2.1.1: Help! XEmacs just crashed on me!
------------------------------------------
-
-First of all, don't panic. Whenever XEmacs crashes, it tries extremely
-hard to auto-save all of your files before dying. (The main time that
-this will not happen is if the machine physically lost power or if you
-killed the XEmacs process using `kill -9'). The next time you try to
-edit those files, you will be informed that a more recent auto-save
-file exists. You can use `M-x recover-file' to retrieve the auto-saved
-version of the file.
-
- You can use the command `M-x recover-session' after a crash to pick
-up where you left off.
-
- Now, XEmacs is not perfect, and there may occasionally be times, or
-particular sequences of actions, that cause it to crash. If you can
-come up with a reproducible way of doing this (or even if you have a
-pretty good memory of exactly what you were doing at the time), the
-maintainers would be very interested in knowing about it. The best way
-to report a bug is using `M-x report-emacs-bug' (or by selecting `Send
-Bug Report...' from the Help menu). If that won't work (e.g. you can't
-get XEmacs working at all), send ordinary mail to <crashes@xemacs.org>.
-_MAKE SURE_ to include the output from the crash, especially including
-the Lisp backtrace, as well as the XEmacs configuration from `M-x
-describe-installation' (or equivalently, the file `Installation' in the
-top of the build tree). Please note that the `crashes' address is
-exclusively for crash reports. The best way to report bugs in general
-is through the `M-x report-emacs-bug' interface just mentioned, or if
-necessary by emailing <xemacs-beta@xemacs.org>. Note that the
-developers do _not_ usually follow `comp.emacs.xemacs' on a regular
-basis; thus, this is better for general questions about XEmacs than bug
-reports.
-
- If at all possible, include a C stack backtrace of the core dump that
-was produced. This shows where exactly things went wrong, and makes it
-much easier to diagnose problems. To do this under Unix, you need to
-locate the core file (it's called `core', and is usually sitting in the
-directory that you started XEmacs from, or your home directory if that
-other directory was not writable). Then, go to that directory and
-execute a command like:
-
- gdb `which xemacs` core
-
- and then issue the command `where' to get the stack backtrace. You
-might have to use `dbx' or some similar debugger in place of `gdb'. If
-you don't have any such debugger available, complain to your system
-administrator.
-
- It's possible that a core file didn't get produced, in which case
-you're out of luck. Go complain to your system administrator and tell
-him not to disable core files by default. Also see *Note Q2.1.15::,
-for tips and techniques for dealing with a debugger.
-
- If you're under Microsoft Windows, you're out of luck unless you
-happen to have a debugging aid installed on your system, for example
-Visual C++. In this case, the crash will result in a message giving
-you the option to enter a debugger (for example, by pressing `Cancel').
-Do this and locate the stack-trace window. (If your XEmacs was built
-without debugging information, the stack trace may not be very useful.)
-
- When making a problem report make sure that:
-
- 1. Report *all* of the information output by XEmacs during the crash.
-
- 2. You mention what O/S & Hardware you are running XEmacs on.
-
- 3. What version of XEmacs you are running.
-
- 4. What build options you are using.
-
- 5. If the problem is related to graphics and you are running Unix, we
- will also need to know what version of the X Window System you are
- running, and what window manager you are using.
-
- 6. If the problem happened on a TTY, please include the terminal type.
-
- Much of the information above is automatically generated by `M-x
-report-emacs-bug'. Even more, and often useful, information can be
-generated by redirecting the output of `make' and `make check' to a
-file (`beta.err' is the default used by `build-report'), and executing
-`M-x build-report'.

-Q2.1.2: Cryptic Minibuffer messages.
-------------------------------------
-
-When I try to use some particular option of some particular package, I
-get a cryptic error in the minibuffer.
-
- If you can't figure out what's going on, select Options/General
-Options/Debug on Error from the Menubar and then try and make the error
-happen again. This will give you a backtrace that may be enlightening.
-If not, try reading through this FAQ; if that fails, you could try
-posting to comp.emacs.xemacs (making sure to include the backtrace) and
-someone may be able to help. If you can identify which Emacs lisp
-source file the error is coming from you can get a more detailed stack
-backtrace by doing the following:
-
- 1. Visit the .el file in an XEmacs buffer.
-
- 2. Issue the command `M-x eval-current-buffer'.
-
- 3. Reproduce the error.
-
- Depending on the version of XEmacs, you may either select View->Show
-Message Log (recent versions), Edit->Show Messages (some earlier
-versions) or Help->Recent Keystrokes/Messages (other earlier versions)
-from the menubar to see the most recent messages. This command is bound
-to `C-h l' by default.

-Q2.1.3: Translation Table Syntax messages at Startup
-----------------------------------------------------
-
-I get tons of translation table syntax error messages during startup.
-How do I get rid of them?
-
- There are two causes of this problem. The first usually only strikes
-people using the prebuilt binaries. The culprit in both cases is the
-file `XKeysymDB'.
-
- * The binary cannot find the `XKeysymDB' file. The location is
- hardcoded at compile time so if the system the binary was built on
- puts it a different place than your system does, you have
- problems. To fix, set the environment variable `XKEYSYMDB' to the
- location of the `XKeysymDB' file on your system or to the location
- of the one included with XEmacs which should be at
- `<xemacs_root_directory>/lib/xemacs-19.16/etc/XKeysymDB'.
-
- * The binary is finding the XKeysymDB but it is out-of-date on your
- system and does not contain the necessary lines. Either ask your
- system administrator to replace it with the one which comes with
- XEmacs (which is the stock R6 version and is backwards compatible)
- or set your `XKEYSYMDB' variable to the location of XEmacs's
- described above.

-Q2.1.15: How to debug an XEmacs problem with a debugger
--------------------------------------------------------
-
-If XEmacs does crash on you, one of the most productive things you can
-do to help get the bug fixed is to poke around a bit with the debugger.
-Here are some hints:
-
- * First of all, if the crash is at all reproducible, consider very
- strongly recompiling your XEmacs with debugging symbols and with no
- optimization (e.g. with GCC use the compiler flags `-g -O0' -
- that's an "oh" followed by a zero), and with the configure options
- `--debug=yes' and `--error-checking=all'. This will make your
- XEmacs run somewhat slower, but you are a lot more likely to catch
- the problem earlier (closer to its source). It makes it a lot
- easier to determine what's going on with a debugger.
-
- * If it's not a true crash (_i.e._, XEmacs is hung, or a zombie
- process), or it's inconvenient to run XEmacs again because XEmacs
- is already running or is running in batch mode as part of a bunch
- of scripts, you may be able to attach to the existing process with
- your debugger. Most debuggers let you do this by substituting the
- process ID for the core file when you invoke the debugger from the
- command line, or by using the `attach' command or something
- similar.
-
- * If you're able to run XEmacs under a debugger and reproduce the
- crash, here are some things you can do:
-
- * If XEmacs is hitting an assertion failure, put a breakpoint on
- `assert_failed()'.
-
- * If XEmacs is hitting some weird Lisp error that's causing it to
- crash (e.g. during startup), put a breakpoint on
- `signal_1()'--this is declared static in eval.c.
-
- * If XEmacs is outputting lots of X errors, put a breakpoint on
- `x_error_handler()'; that will tell you which call is causing them.
-
- * Internally, you will probably see lots of variables that hold
- objects of type `Lisp_Object'. These are references to Lisp
- objects. Printing them out with the debugger probably won't be too
- useful--you'll likely just see a number. To decode them, do this:
-
- call dp (OBJECT)
-
- where OBJECT is whatever you want to decode (it can be a variable,
- a function call, etc.). This uses the Lisp printing routines to
- out a readable representation on the TTY from which the xemacs
- process was invoked.
-
- * If you want to get a Lisp backtrace showing the Lisp call stack,
- do this:
-
- call db ()
-
- * Using `dp' and `db' has two disadvantages - they can only be used
- with a running (including hung or zombie) xemacs process, and they
- do not display the internal C structure of a Lisp Object. Even if
- all you've got is a core dump, all is not lost.
-
- If you're using GDB, there are some macros in the file
- `src/.gdbinit' in the XEmacs source distribution that should make
- it easier for you to decode Lisp objects. This file is
- automatically read by gdb if gdb is run in the directory where
- xemacs was built, and contains these useful macros to inspect the
- state of xemacs:
-
- `pobj'
- Usage: pobj lisp_object
- Print the internal C representation of a lisp object.
-
- `xtype'
- Usage: xtype lisp_object
- Print the Lisp type of a lisp object.
-
- `lbt'
- Usage: lbt
- Print the current Lisp stack trace. Requires a running
- xemacs process. (It works by calling the db routine
- described above.)
-
- `ldp'
- Usage: ldp lisp_object
- Print a Lisp Object value using the Lisp printer. Requires a
- running xemacs process. (It works by calling the dp routine
- described above.)
-
- `run-temacs'
- Usage: run-temacs
- Run temacs interactively, like xemacs. Use this with
- debugging tools (like purify) that cannot deal with dumping,
- or when temacs builds successfully, but xemacs does not.
-
- `dump-temacs'
- Usage: dump-temacs
- Run the dumping part of the build procedure. Use when
- debugging temacs, not xemacs! Use this when temacs builds
- successfully, but xemacs does not.
-
- `check-xemacs'
- Usage: check-xemacs
- Run the test suite. Equivalent to 'make check'.
-
- `check-temacs'
- Usage: check-temacs
- Run the test suite on temacs. Equivalent to 'make
- check-temacs'. Use this with debugging tools (like purify)
- that cannot deal with dumping, or when temacs builds
- successfully, but xemacs does not.
-
- If you are using Sun's `dbx' debugger, there is an equivalent file
- `src/.dbxrc', which defines the same commands for dbx.
-
- * If you're using a debugger to get a C stack backtrace and you're
- seeing stack traces with some of the innermost frames mangled, it
- may be due to dynamic linking. (This happens especially under
- Linux.) Consider reconfiguring with `--dynamic=no'. Also,
- sometimes (again under Linux), stack backtraces of core dumps will
- have the frame where the fatal signal occurred mangled; if you can
- obtain a stack trace while running the XEmacs process under a
- debugger, the stack trace should be clean.
-
- Curtiss <1CMC3466@ibm.mtsac.edu> suggests upgrading to ld.so
- version 1.8 if dynamic linking and debugging is a problem on Linux.
-
- * If you're using a debugger to get a C stack backtrace and you're
- getting a completely mangled and bogus stack trace, it's probably
- due to one of the following:
-
- a. Your executable has been stripped. Bad news. Tell your
- sysadmin not to do this--it doesn't accomplish anything
- except to save a bit of disk space, and makes debugging much
- much harder.
-
- b. Your stack is getting trashed. Debugging this is hard; you
- have to do a binary-search type of narrowing down where the
- crash occurs, until you figure out exactly which line is
- causing the problem. Of course, this only works if the bug
- is highly reproducible. Also, in many cases if you run
- XEmacs from the debugger, the debugger can protect the stack
- somewhat. However, if the stack is being smashed, it is
- typically the case that there is a wild pointer somewhere in
- the program, often quite far from where the crash occurs.
-
- c. If your stack trace has exactly one frame in it, with address
- 0x0, this could simply mean that XEmacs attempted to execute
- code at that address, e.g. through jumping to a null function
- pointer. Unfortunately, under those circumstances, GDB under
- Linux doesn't know how to get a stack trace. (Yes, this is
- the fourth Linux-related problem I've mentioned. I have no
- idea why GDB under Linux is so bogus. Complain to the GDB
- authors, or to comp.os.linux.development.system.) Again,
- you'll have to use the narrowing-down process described above.
-
- d. You will get a Lisp backtrace output when XEmacs crashes, so
- you'll have something useful.
-
-
- * If you compile with the newer gcc variants gcc-2.8 or egcs, you
- will also need gdb 4.17 or above. Earlier releases of gdb can't
- handle the debug information generated by the newer compilers.
-
- * In versions of XEmacs before 21.2.27, `src/.gdbinit' was named
- `src/gdbinit'. This had the disadvantage of not being sourced
- automatically by gdb, so you had to set that up yourself.
-
- * If you are running Microsoft Windows, the the file `nt/README' for
- further information about debugging XEmacs.

-------------------------------------------------------------------
-
-David Moore <dmoore@ucsd.edu> writes:
-
- Two things you can do:
-
- 1) C level:
-
- When you see it going mad like this, you might want to use gdb
- from an 'xterm' to attach to the running process and get a stack
- trace. To do this just run:
-
- gdb /path/to/xemacs/xemacs ####
-
- Where `####' is the process id of your xemacs, instead of
- specifying the core. When gdb attaches, the xemacs will stop [1]
- and you can type `where' in gdb to get a stack trace as usual. To
- get things moving again, you can just type `quit' in gdb. It'll
- tell you the program is running and ask if you want to quit
- anyways. Say 'y' and it'll quit and have your emacs continue from
- where it was at.
-
- 2) Lisp level:
-
- Turn on debug-on-quit early on. When you think things are going
- slow hit C-g and it may pop you in the debugger so you can see
- what routine is running. Press `c' to get going again.

- debug-on-quit doesn't work if something's turned on inhibit-quit

-3.0: Customization - Emacs Lisp and `init.el'/`.emacs'
-======================================================
-
-Q3.0.1: What version of Emacs am I running?
--------------------------------------------
-
-How can `init.el'/`.emacs' determine which of the family of Emacsen I
-am using?
-
- To determine if you are currently running GNU Emacs 18, GNU Emacs 19,
-XEmacs 19, XEmacs 20, or Epoch, and use appropriate code, check out the
-example given in `etc/sample.init.el' (`etc/sample.emacs' in XEmacs
-versions prior to 21.4). There are other nifty things in there as well!
-
- For all new code, all you really need to do is:
-
- (defvar running-xemacs (string-match "XEmacs\\|Lucid" emacs-version))

-
-Q3.0.2: How can I evaluate Emacs-Lisp expressions?
---------------------------------------------------
-
-I know I can evaluate Elisp expressions from `*scratch*' buffer with
-`C-j' after the expression. How do I do it from another buffer?
-
- Press `M-:' (the default binding of `eval-expression'), and enter
-the expression to the minibuffer.

-
-Q3.0.3: `(setq tab-width 6)' behaves oddly.
--------------------------------------------
-
-If you put `(setq tab-width 6)' in your `init.el'/`.emacs' file it does
-not work! Is there a reason for this? If you do it at the EVAL prompt
-it works fine!! How strange.
-
- Use `setq-default' instead, since `tab-width' is all-buffer-local.

-
-Q3.0.4: How can I add directories to the `load-path'?
------------------------------------------------------
-
-Here are two ways to do that, one that puts your directories at the
-front of the load-path, the other at the end:
-
- ;;; Add things at the beginning of the load-path, do not add
- ;;; duplicate directories:
- (pushnew "bar" load-path :test 'equal)
-
- (pushnew "foo" load-path :test 'equal)
-
- ;;; Add things at the end, unconditionally
- (setq load-path (nconc load-path '("foo" "bar")))

-Q3.0.5: How to check if a lisp function is defined?
----------------------------------------------------
-
-Use the following elisp:
-
- (fboundp 'foo)
-
- It's almost always a mistake to test `emacs-version' or any similar
-variables.
-
- Instead, use feature-tests, such as `featurep', `boundp', `fboundp',
-or even simple behavioral tests, eg.:
-
- (defvar foo-old-losing-code-p
- (condition-case nil (progn (losing-code t) nil)
- (wrong-number-of-arguments t)))
-
- There is an incredible amount of broken code out there which could
-work much better more often in more places if it did the above instead
-of trying to divine its environment from the value of one variable.

-------------------------------------------------------------
-
-It would be good having it in a buffer, as the output of `(face-list)'
-is too wide to fit to a minibuffer.
-
- Evaluate the expression in the `*scratch*' buffer with point after
-the rightmost paren and typing `C-j'.
-
- If the minibuffer smallness is the only problem you encounter, you
-can simply press `C-h l' to get the former minibuffer contents in a
-buffer.

-Q3.0.9: What is `Customize'?
-----------------------------
-
-Starting with XEmacs 20.2 there is new system 'Customize' for
-customizing XEmacs options.
-
- You can access `Customize' from the `Options' menu or invoking one
-of customize commands by typing eg. `M-x customize', `M-x
-customize-face', `M-x customize-variable' or `M-x customize-apropos'.
-
- Starting with XEmacs 20.3 there is also new `browser' mode for
-Customize. Try it out with `M-x customize-browse'

-3.1: X Window System & Resources
-================================
-
-Q3.1.1: Where is a list of X resources?
----------------------------------------
-
-Search through the `NEWS' file for `X Resources'. A fairly
-comprehensive list is given after it.
-
- In addition, an `app-defaults' file `etc/Emacs.ad' is supplied,
-listing the defaults. The file `etc/sample.Xresources' gives a
-different set of defaults that you might consider for installation in
-your `~/.Xresources' file. It is nearly the same as `etc/Emacs.ad',
-but a few entries are altered. Be careful about installing the
-contents of this file into your `.Xresources' (or legacy `.Xdefaults')
-file if you use GNU Emacs under X11 as well.

-Q3.1.7: `xemacs -name junk' doesn't work?
------------------------------------------
-
-When I run `xterm -name junk', I get an xterm whose class name
-according to xprop, is `junk'. This is the way it's supposed to work,
-I think. When I run `xemacs -name junk' the class name is not set to
-`junk'. It's still `emacs'. What does `xemacs -name' really do? The
-reason I ask is that my window manager (fvwm) will make a window sticky
-and I use XEmacs to read my mail. I want that XEmacs window to be
-sticky, without having to use the window manager's function to set the
-window sticky. What gives?
-
- `xemacs -name' sets the application name for the program (that is,
-the thing which normally comes from `argv[0]'). Using `-name' is the
-same as making a copy of the executable with that new name. The
-`WM_CLASS' property on each frame is set to the frame-name, and the
-application-class. So, if you did `xemacs -name FOO' and then created
-a frame named BAR, you'd get an X window with WM_CLASS = `( "BAR",
-"Emacs")'. However, the resource hierarchy for this widget would be:
-
- Name: FOO .shell .container .BAR
- Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
-
- instead of the default
-
- Name: xemacs.shell .container .emacs
- Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
-
- It is arguable that the first element of WM_CLASS should be set to
-the application-name instead of the frame-name, but I think that's less
-flexible, since it does not give you the ability to have multiple frames
-with different WM_CLASS properties. Another possibility would be for
-the default frame name to come from the application name instead of
-simply being `emacs'. However, at this point, making that change would
-be troublesome: it would mean that many users would have to make yet
-another change to their resource files (since the default frame name
-would suddenly change from `emacs' to `xemacs', or whatever the
-executable happened to be named), so we'd rather avoid it.
-
- To make a frame with a particular name use:
-
- (make-frame '((name . "the-name")))

-Q3.2.2: How do I set the text, menu and modeline fonts?
--------------------------------------------------------
-
-Note that you should use `Emacs.' and not `Emacs*' when setting face
-values.
-
- In `.Xresources':
-
- Emacs.default.attributeFont: -*-*-medium-r-*-*-*-120-*-*-m-*-*-*
- Emacs*menubar*font: fixed
- Emacs.modeline.attributeFont: fixed
-
- This is confusing because `default' and `modeline' are face names,
-and can be found listed with all faces in the current mode by using
-`M-x set-face-font (enter) ?'. They use the face-specific resource
-`attributeFont'.
-
- On the other hand, `menubar' is a normal X thing that uses the
-resource `font'. With Motif it _may be_ necessary to use `fontList'
-_instead of_ `font'. In _non-Motif_ configurations with Mule it _is_
-necessary to use `fontSet' instead of `font'. (Sorry, there just is no
-simple recipe here.)

-
- Answer: No, but you can start Netscape before XEmacs, and it will use
-the closest available color if the colormap is full. You can also limit
-the number of colors Netscape uses, using the flags -mono, -ncols <#> or
--install (for mono, limiting to <#> colors, or for using a private color

-Q3.2.7: How do I display non-ASCII characters?
-----------------------------------------------
-
-If you're using a Mule-enabled XEmacs, then display is automatic. If
-you're not seeing the characters you expect, either (1) you don't have
-appropriate fonts available or (2) XEmacs did not correctly detect the
-coding system (*note Recognize Coding: (xemacs)Recognize Coding.). In
-case (1), install fonts as is customary for your platform. In case
-(2), you need to tell XEmacs explicitly what coding systems you're
-using. *Note Specify Coding: (xemacs)Specify Coding.
-
- If your XEmacs is not Mule-enabled, and for some reason getting a
-Mule-enabled XEmacs seems like the wrong thing to do, all is not lost.
-You can arrange it by brute force. In `event-Xt.c' (suppress the urge
-to look in this file--play Doom instead, because you'll survive
-longer), it is written:
-
- In a non-Mule world, a user can still have a multi-lingual editor,

-Q3.3.5: How can one change the modeline color based on the mode used?
----------------------------------------------------------------------
-
-You can use something like the following:
-
- (add-hook 'lisp-mode-hook
- (lambda ()
- (set-face-background 'modeline "red" (current-buffer))))
-
- Then, when editing a Lisp file (i.e. when in Lisp mode), the modeline
-colors change from the default set in your `init.el'/`.emacs'. The
-change will only be made in the buffer you just entered (which contains
-the Lisp file you are editing) and will not affect the modeline colors
-anywhere else.
-
- Notes:
-
- * The hook is the mode name plus `-hook'. eg. c-mode-hook,
- c++-mode-hook, emacs-lisp-mode-hook (used for your
- `init.el'/`.emacs' or a `xx.el' file), lisp-interaction-mode-hook
- (the `*scratch*' buffer), text-mode-hook, etc.
-
- * Be sure to use `add-hook', not `(setq c-mode-hook xxxx)',
- otherwise you will erase anything that anybody has already put on
- the hook.
-
- * You can also do `(set-face-font 'modeline FONT)', eg.
- `(set-face-font 'modeline "*bold-r-normal*140-100-100*"
- (current-buffer))' if you wish the modeline font to vary based on
- the current mode.
-
- There are additional modeline faces, `modeline-buffer-id',
-`modeline-mousable', and `modeline-mousable-minor-mode', which you may

-3.5: The Keyboard
-=================
-
-Q3.5.1: How can I bind complex functions (or macros) to keys?
--------------------------------------------------------------
-
-As an example, say you want the `paste' key on a Sun keyboard to insert
-the current Primary X selection at point. You can accomplish this with:
-
- (define-key global-map [f18] 'x-insert-selection)
-
- However, this only works if there is a current X selection (the
-selection will be highlighted). The functionality I like is for the
-`paste' key to insert the current X selection if there is one,
-otherwise insert the contents of the clipboard. To do this you need to
-pass arguments to `x-insert-selection'. This is done by wrapping the
-call in a 'lambda form:
-
- (global-set-key [f18]
- (lambda () (interactive) (x-insert-selection t nil)))
-
- This binds the f18 key to a "generic" functional object. The
-interactive spec is required because only interactive functions can be
-bound to keys.
-
- For the FAQ example you could use:
-
- (global-set-key [(control ?.)]
- (lambda () (interactive) (scroll-up 1)))
- (global-set-key [(control ?;)]
- (lambda () (interactive) (scroll-up -1)))
-
- This is fine if you only need a few functions within the lambda body.
-If you're doing more it's cleaner to define a separate function as in
-question 3.5.3 (*note Q3.5.3::).

-Q3.7.1: How can I turn off Mouse pasting?
------------------------------------------
-
-I keep hitting the middle mouse button by accident and getting stuff
-pasted into my buffer so how can I turn this off?
-
- Here is an alternative binding, whereby the middle mouse button
-selects (but does not cut) the expression under the mouse. Clicking
-middle on a left or right paren will select to the matching one. Note
-that you can use `define-key' or `global-set-key'.
-
- (defun mouse-set-point-and-select (event)
- "Sets the point at the mouse location, then marks following form"
- (interactive "@e")
- (mouse-set-point event)

------------------------------------------------------------------
-
-Use, for instance, `[(meta button1)]'. For example, here is a common
-setting for Common Lisp programmers who use the bundled `ilisp'
-package, whereby meta-button1 on a function name will find the file
-where the function name was defined, and put you at that location in
-the source file.
-
- [Inside a function that gets called by the lisp-mode-hook and

----------------------------------------------------------------------------
-
-By default XEmacs pastes X selections where the mouse pointer is. How

-
- Examine the function `mouse-yank', by typing `C-h f mouse-yank

-Q3.7.7: How do I select a rectangular region?
----------------------------------------------
-
-Just select the region normally, then use the rectangle commands (e.g.
-`kill-rectangle' on it. The region does not highlight as a rectangle,
-but the commands work just fine.
-
- To actually sweep out rectangular regions with the mouse you can use
-`mouse-track-do-rectangle' which is assigned to `M-button1'. Then use
-rectangle commands.
-
- You can also do the following to change default behavior to sweep out
-rectangular regions:
-
- (setq mouse-track-rectangle-p t)
-
- Starting with XEmacs-20.2 you can also change this with Customize.
-Select from the `Options' menu `Advanced
-(Customize)->Emacs->Editing->Mouse->Track Rectangle...' or type `M-x
-customize <RET> mouse <RET>'.
-
- mouse-track-do-rectangle: (event)
- -- an interactive compiled Lisp function.
- Like `mouse-track' but selects rectangles instead of regions.

-Q3.8.4: Resources like `Emacs*menubar*font' are not working?
-------------------------------------------------------------
-
-I am trying to use a resource like `Emacs*menubar*font' to set the font
-of the menubar but it's not working.
-
- In Motif, the use of `font' resources is obsoleted in order to
-support internationalization. If you are using the real Motif menubar,
-this resource is not recognized at all; you have to say:
-
- Emacs*menubar*fontList: FONT
-
- If you are using the Lucid menubar, for backward compatibility with
-existing user configurations, the `font' resource is recognized. Since
-this is not supported by Motif itself, the code is a kludge and the
-`font' resource will be recognized only if the `fontList' resource
-resource is unset. This means that the resource
-
- *fontList: FONT
-
- will override
-
- Emacs*menubar*font: FONT
-
- even though the latter is more specific.
-
- In non-Motif configurations using `--with-mule' and `--with-xfs' it
-_is_ necessary to use the `fontSet' resource _instead of_ the `font'
-resource. The backward compatibility kludge was never implemented for
-non-Motif builds. Example:
-
- *fontSet: FONT

- (set-specifier default-toolbar-visible-p
- (not (specifier-instance default-toolbar-visible-p))))
- (global-set-key "\C-xT" 'my-toggle-toolbar)
-
- There are redisplay bugs in 19.14 that may make the preceding result
-in a messed-up display, especially for frames with multiple windows.
-You may need to resize the frame before XEmacs completely realizes the
-toolbar is really gone.
-
- Thanks to Martin Buchholz <martin@xemacs.org> for the correct code.

-3.9: Scrollbars
-===============
-
-Q3.9.1: How can I disable the scrollbar?
-----------------------------------------
-
-To disable them for all frames, add the following line to your
-`.Xresources':
-
- Emacs.scrollBarWidth: 0
-
- Or select from the `Options' menu `Frame Appearance->Scrollbars'.
-Remember to save options.
-
- To turn the scrollbar off on a per-frame basis, use the following
-function:
-
- (set-specifier scrollbar-width 0 (selected-frame))
-
- You can actually turn the scrollbars on at any level you want by
-substituting for (selected-frame) in the above command. For example, to
-turn the scrollbars off only in a single buffer:
-
- (set-specifier scrollbar-width 0 (current-buffer))

--------------------------------------------------------------
-

-
- ! Motif scrollbars
-
- Emacs*XmScrollBar.Background: skyblue
- Emacs*XmScrollBar.troughColor: lightgray
-
- ! Athena scrollbars
-
- Emacs*Scrollbar.Foreground: skyblue

-
-Q3.9.3: Moving the scrollbar can move the point; can I disable this?
---------------------------------------------------------------------
-
-When I move the scrollbar in an XEmacs window, it moves the point as
-well, which should not be the default behavior. Is this a bug or a
-feature? Can I disable it?
-
- The current behavior is a feature, not a bug. Point remains at the
-same buffer position as long as that position does not scroll off the
-screen. In that event, point will end up in either the upper-left or
-lower-left hand corner.
-
- This cannot be changed.

-
-Q3.9.4: How can I turn off automatic horizontal scrolling in specific modes?
-----------------------------------------------------------------------------
-
-Do `(setq truncate-lines t)' in the mode-hooks for any modes in which
-you want lines truncated.
-
- More precisely: If `truncate-lines' is nil, horizontal scrollbars
-will never appear. Otherwise, they will appear only if the value of
-`scrollbar-height' for that buffer/window/etc. is non-zero. If you do
-
- (set-specifier scrollbar-height 0)
-
- then horizontal scrollbars will not appear in truncated buffers
-unless the package specifically asked for them.

-3.10: Text Selections
-=====================
-
-Q3.10.1: How can I turn off or change highlighted selections?
--------------------------------------------------------------
-
-The `zmacs' mode allows for what some might call gratuitous
-highlighting for selected regions (either by setting mark or by using
-the mouse). This is the default behavior. To turn off, add the
-following line to your `init.el'/`.emacs' file:
-
- (setq zmacs-regions nil)
-
- Starting with XEmacs-20.2 you can also change this with Customize.
-Select from the `Options' menu `Advanced
-(Customize)->Emacs->Editing->Basics->Zmacs Regions' or type `M-x
-customize <RET> editing-basics <RET>'.
-
- To change the face for selection, look at `Options->Customize' on
-the menubar.

-
-Q3.10.2: How do I get that typing on an active region removes it?
------------------------------------------------------------------
-
-I want to change things so that if I select some text and start typing,
-the typed text replaces the selected text, similar to Motif.
-
- You want to use something called "pending delete". Pending delete
-is what happens when you select a region (with the mouse or keyboard)
-and you press a key to replace the selected region by the key you typed.
-Usually backspace kills the selected region.
-
- To get this behavior, add the following lines to your
-`init.el'/`.emacs':
-
- (cond
- ((fboundp 'turn-on-pending-delete)
- (turn-on-pending-delete))
- ((fboundp 'pending-delete-on)
- (pending-delete-on t)))
-
- Note that this will work with both Backspace and Delete. This code
-is a tad more complicated than it has to be for XEmacs in order to make
-it more portable.

-Q3.10.3: Can I turn off the highlight during isearch?
------------------------------------------------------
-
-I do not like my text highlighted while I am doing isearch as I am not
-able to see what's underneath. How do I turn it off?
-
- Put the following in your `init.el'/`.emacs':
-
- (setq isearch-highlight nil)
-
- Starting with XEmacs-20.2 you can also change this with Customize.
-Type `M-x customize-variable <RET> isearch-highlight <RET>'.
-
- Note also that isearch-highlight affects query-replace and ispell.
-Instead of disabling isearch-highlight you may find that a better
-solution consists of customizing the `isearch' face.

-Q3.10.5: The region disappears when I hit the end of buffer while scrolling.
-----------------------------------------------------------------------------
-
-This has been fixed by default starting with XEmacs-20.3.
-
- With older versions you can turn this feature (if it indeed is a
-feature) off like this:
-
- (defadvice scroll-up (around scroll-up freeze)
- (interactive "_P")
- (let ((zmacs-region-stays t))
- (if (interactive-p)
- (condition-case nil
- ad-do-it
- (end-of-buffer (goto-char (point-max))))
- ad-do-it)))
-
- (defadvice scroll-down (around scroll-down freeze)
- (interactive "_P")
- (let ((zmacs-region-stays t))
- (if (interactive-p)
- (condition-case nil
- ad-do-it
- (beginning-of-buffer (goto-char (point-min))))

-Q3.10.6: Why is killing so slow?
---------------------------------
-
-This actually is an X Windows question, although you'll notice it with
-keyboard operations as well as while using the GUI. Basically, there
-are four ways to communicate interprogram via the X server:
-
-*Primary selection*
- a transient selection that gets replaced every time a new
- selection is made
-
-*Secondary selection*
- for "exchanging" with the primary selection
-
-*Cut buffers*
- a clipboard internal to the X server (deprecated)
-
-*Clipboard selection*
- a selection with a notification protocol that allows a separate
- app to manage the clipboard
-
- The cut buffers are deprecated because managing them is even more
-inefficient than the clipboard notification protocol. The primary
-selection works fine for many users and applications, but is not very
-robust under intensive or sophisticated use.
-
- In Motif and MS Windows, a clipboard has become the primary means for
-managing cut and paste. These means that "modern" applications tend to
-be oriented toward a true clipboard, rather than the primary selection.
-(On Windows, there is nothing equivalent to the primary selection.)
-It's not that XEmacs doesn't support the simple primary selection
-method, it's that more and more other applications don't.
-
- So the slowdown occurs because XEmacs now engages in the clipboard
-notification protocol on _every_ kill. This is especially slow on
-Motif.
-
- With most people running most clients and server on the same host,
-and many of the rest working over very fast communication, you may
-expect that the situation is not going to improve.
-
- There are a number of workarounds. The most effective is to use a
-special command to do selection ownership only when you intend to paste
-to another application. Useful commands are `kill-primary-selection'
-and `copy-primary-selection'. These work only on text selected with
-the mouse (probably; experiment), and are bound by default to the `Cut'
-and `Copy', respectively, buttons on the toolbar.
-`copy-primary-selection' is also bound to `C-Insert'. You can yank the
-clipboard contents with `yank-primary-selection', bound to the `Paste'
-toolbar button and `Sh-Insert'.
-
- If you are communicating by cut and paste with applications that use
-the primary selection, then you can customize
-`interprogram-cut-function' to `nil', restoring the XEmacs version 20
-behavior. How can you tell if a program will support this?
-Motifly-correct programs require the clipboard; you lose. For others,
-only by trying it. You also need to customize the complementary
-`interprogram-paste-function' to `nil'. (Otherwise XEmacs-to-XEmacs
-pastes will not work correctly.)
-
- You may get some relief on Motif by setting
-`x-selection-strict-motif-ownership' to nil, but this means you will
-only intermittently be able to paste XEmacs kills to Motif applications.
-
- Thanks to Jeff Mincy and Glynn Clements for corrections.

-Q4.0.9: rmail or VM gets an error incorporating new mail.
----------------------------------------------------------
-
-Quoting the XEmacs PROBLEMS file:
-
- rmail and VM get new mail from `/usr/spool/mail/$USER' using a
- program called `movemail'. This program interlocks with
- `/bin/mail' using the protocol defined by `/bin/mail'.
-
- There are two different protocols in general use. One of them
- uses the `flock' system call. The other involves creating a lock
- file; `movemail' must be able to write in `/usr/spool/mail' in
- order to do this. You control which one is used by defining, or
- not defining, the macro `MAIL_USE_FLOCK' in `config.h' or the m-
- or s- file it includes.
-
- *IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR
- SYSTEM, YOU CAN LOSE MAIL!*
-
- If your system uses the lock file protocol, and fascist
- restrictions prevent ordinary users from writing the lock files in
- `/usr/spool/mail', you may need to make `movemail' setgid to a
- suitable group such as `mail'. You can use these commands (as
- root):
-
- chgrp mail movemail
- chmod 2755 movemail
-
- If your system uses the lock file protocol, and fascist
- restrictions prevent ordinary users from writing the lock files in
- `/usr/spool/mail', you may need to make `movemail' setgid to a
- suitable group such as `mail'. To do this, use the following
- commands (as root) after doing the make install.
-
- chgrp mail movemail
- chmod 2755 movemail
-
- Installation normally copies movemail from the build directory to
- an installation directory which is usually under `/usr/local/lib'.
- The installed copy of `movemail' is usually in the directory
- `/usr/local/lib/emacs/VERSION/TARGET'. You must change the group
- and mode of the installed copy; changing the group and mode of the
- build directory copy is ineffective.

------------------------------------------
-
-TM stands for "Tools for MIME" and not Tiny MIME. TM integrates with
-all major XEmacs packages like Gnus (all flavors), VM, MH-E, and
-mailcrypt. It provides totally transparent and trouble-free MIME
-support. When appropriate a message will be decoded in place in an
-XEmacs buffer.
-
- TM now comes as a package with XEmacs 19.16 and XEmacs 20.2.
-
- TM was written by MORIOKA Tomohiko <morioka@jaist.ac.jp> and
-KOBAYASHI Shuhei <shuhei-k@jaist.ac.jp>.
-
- It is based on the work of UMEDA Masanobu
-<umerin@mse.kyutech.ac.jp>, the original writer of GNUS.
-
- The following information is from the `README':
-
- "tm" is a MIME package for GNU Emacs. tm has following functions:
-
- * MIME style multilingual header.
-
- * MIME message viewer (mime/viewer-mode).
-
- * MIME message composer (mime/editor-mode).
-
- * MIME extenders for mh-e, GNUS, RMAIL and VM.
-
- tm is available from following anonymous ftp sites:
- * `ftp://ftp.unicamp.br/pub/mail/mime/tm/' (Brasil).
-
- * `ftp://ftp.th-darmstadt.de/pub/editors/GNU-Emacs/lisp/mime/'
- (Germany).
-
- * `ftp://ftp.tnt.uni-hannover.de/pub/editors/xemacs/contrib/'
- (Germany).

- Don't let the installation procedure & instructions stop you from
-trying this package out--it's much simpler than it looks, and once
-installed, trivial to use.
-
- Steve Youngs <youngs@xemacs.org> writes:

-4.6: Infodock
-=============
-
-Q4.6.1: What is Infodock?
--------------------------
-
-InfoDock (http://sourceforge.net/projects/infodock/) is an integrated
-productivity toolset, mainly aimed at technical people, hosted at
-SourceForge.
-
- InfoDock is built atop the XEmacs variant of GNU Emacs and so has
-all of the power of Emacs, but with an easier to use and more
-comprehensive menu-based user interface. The bottom portion of this
-text describes how it differs from XEmacs and GNU Emacs from the Free
-Software Foundation.
-
- InfoDock is aimed at people who want a free, turn-key productivity
-environment. Although InfoDock is customizable, it is not intended for
-people who like basic versions of Emacs which need to be customized
-extensively for local use; standard Emacs distributions are better for
-such uses. InfoDock is for those people who want a complete,
-pre-customized environment in one package, which they need not touch
-more than once or twice a year to update to new revisions.
-
- InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
-and Intel Linux systems. It is intended for use on a color display,
-although most features will work on monochrome monitors. Simply unpack
-InfoDock according to the instructions in the ID-INSTALL file and you
-are ready to run.
-
- The InfoDock Manual is concise, yet sufficient as a user guide for
-users who have never used an Emacs-type editor before. For users who
-are already familiar with Emacs, it supplements the information in the
-GNU Emacs Manual.
-
- InfoDock menus are much more extensive and more mature than standard
-Emacs menus. Each menu offers a `Manual' item which displays
-documentation associated with the menu's functions.
-
-Four types of menubars are provided:
- 1. An extensive menubar providing access to global InfoDock commands.
-
- 2. Mode-specific menubars tailored to the current major mode.
-
- 3. A simple menubar for basic editing to help novices get started
- with InfoDock.
-
- 4. The standard XEmacs menubar.
-
- Most modes also include mode-specific popup menus. Additionally,
-region and rectangle popup menus are included.
-
- `Hyperbole', the everyday information manager, is a core part of
-InfoDock. This provides context-sensitive mouse keys, a rolodex-type
-contact manager, programmable hypertext buttons, and an autonumbered
-outliner with embedded hyperlink anchors.
-
- The `OO-Browser', a multi-language object-oriented code browser, is a
-standard part of InfoDock.
-
- InfoDock saves a more extensive set of user options than other Emacs
-versions.
-
- InfoDock inserts a useful file header in many file types, showing the
-author, summary, and last modification time of each file. A summary
-program can then be used to summarize all of the files in a directory,
-for easy MANIFEST file creation.
-
- Your working set of buffers is automatically saved and restored (if
-you answer yes to a prompt) between InfoDock sessions.
-
- Refined color choices for code highlighting are provided for both
-dark and light background display frames.
-
- The `C-z' key prefix performs frame-based commands which parallel the
-`C-x' key prefix for window-based commands.
-
- The Smart Menu system is included for producing command menus on dumb
-terminals.
-
- Lisp libraries are better categorized according to function.
-
- Extensions and improvements to many areas of Emacs are included,
-such as: paragraph filling, mail reading with Rmail, shell handling,
-outlining, code highlighting and browsing, and man page browsing.
-
- InfoDock questions, answers and discussion should go to the mail list
-<infodock@infodock.com>. Use <infodock-request@infodock.com> to be
-added or removed from the list. Always include your InfoDock version
-number when sending help requests.
-
- InfoDock is available across the Internet via anonymous FTP. To get
-it, first move to a directory into which you want the InfoDock archive
-files placed. We will call this <DIST-DIR>.
-
- cd <DIST-DIR>
-
- Ftp to ftp.xemacs.org (Internet Host ID = 128.174.252.16):
-
- prompt> ftp ftp.xemacs.org
-
- Login as `anonymous' with your own <user-id>@<site-name> as a
-password.
-
- Name (ftp.xemacs.org): anonymous
- 331 Guest login ok, send your complete e-mail address as password.
- Password: -<your-user-id>@<your-domain>
- 230 Guest login ok, access restrictions apply.
-
- Move to the location of the InfoDock archives:
-
- ftp> cd pub/infodock
-
- Set your transfer mode to binary:
-
- ftp> bin
- 200 Type set to I.
-
- Turn off prompting:
-
- ftp> prompt
- Interactive mode off.
-
- Retrieve the InfoDock archives that you want, either by using a `get
-<file>' for each file you want or by using the following to get a
-complete distribution, including all binaries:
-
- ftp> mget ID-INSTALL
- ftp> mget id-*
-
- Close the FTP connection:
-
- ftp> quit
- 221 Goodbye.
-
- Read the `ID-INSTALL' file which you just retrieved for step-by-step
-installation instructions.

-Q4.7.4: Problems installing AUC TeX.
-------------------------------------
-
-Jan Vroonhof <vroonhof@math.ethz.ch> writes:
-
- AUC TeX works fine on both stock Emacs and XEmacs has been doing
- so for a very very long time. This is mostly due to the work of
- Per Abrahamsen <abraham@dina.kvl.dk> (clap clap) in particular his
- `easymenu' package. Which leads to what is probably the problem...
-
- Most problems with AUC TeX are one of two things:
-
- * The TeX-lisp-directory in `tex-site.el' and the makefile don't
- match.
-
- Fix: make sure you configure AUC TeX properly *before* installing.
-
- * You have an old version of easymenu.el in your path.
-
- Fix: use `locate-library' and remove old versions to make sure it
- *only* finds the one that came with XEmacs.

-Q4.7.5: Is there a reason for an Emacs package not to be included in XEmacs?
-----------------------------------------------------------------------------
-
-The reason for an Emacs package not to be included in XEmacs is usually
-one or more of the following:
-
- 1. The package has not been ported to XEmacs. This will typically
- happen when it uses GNU-Emacs-specific features, which make it
- fail under XEmacs.
-
- Porting a package to XEmacs can range from a trivial amount of
- change to a partial or full rewrite. Fortunately, the authors of
- modern packages usually choose to support both Emacsen themselves.
-
- 2. The package has been decided not to be appropriate for XEmacs. It
- may have an equivalent or better replacement within XEmacs, in
- which case the developers may choose not to burden themselves with
- supporting an additional package.
-
- Each package bundled with XEmacs means more work for the
- maintainers, whether they want it or not. If you are ready to
- take over the maintenance responsibilities for the package you
- port, be sure to say so--we will more likely include it.
-
- 3. The package simply hasn't been noted by the XEmacs development. If
- that's the case, the messages like yours are very useful for
- attracting our attention.
-
- 4. The package was noted by the developers, but they simply haven't
- yet gotten around to including/porting it. Wait for the next
- release or, even better, offer your help. It will be gladly
- accepted and appreciated.

-Q4.7.7: Can I edit files on other hosts?
-----------------------------------------
-
-Yes. Of course XEmacs can use any network file system (such as NFS or
-Windows file sharing) you have available, and includes some
-optimizations and safety features appropriate to those environments.
-
- It is also possible to transparently edit files via FTP, ssh, or
-rsh. That is, XEmacs makes a local copy using the transport in the
-background, and automatically refreshes the remote original from that
-copy when you save it. XEmacs also is capable of doing file system
-manipulations like creating and removing directories and files. The
-FTP interface is provided by the standard `efs' package *Note EFS:
-(efs)Top. The ssh/rsh interface is provided by the optional `tramp'
-package *Note TRAMP: (tramp)Top.

-5.0: Major & Minor Modes
-========================
-
-Q5.0.1: How can I do source code highlighting using font-lock?
---------------------------------------------------------------
-
-For most modes, font-lock is already set up and just needs to be turned
-on. This can be done by adding the line:
-
- (require 'font-lock)
-
- to your `init.el'/`.emacs'. (You can turn it on for the current
-buffer and session only by `M-x font-lock-mode'.) See the file
-`etc/sample.init.el' (`etc/sample.emacs' in XEmacs versions prior to
-21.4) for more information.
-
- See also `Syntax Highlighting' from the `Options' menu. Remember to
-save options.

-
-Q5.0.2: I do not like cc-mode. How do I use the old c-mode?
-------------------------------------------------------------
-
-Well, first off, consider if you really want to do this. cc-mode is
-much more powerful than the old c-mode. If you're having trouble
-getting your old offsets to work, try using `c-set-offset' instead.
-You might also consider using the package `cc-compat'.
-
- But, if you still insist, add the following lines to your
-`init.el'/`.emacs':
-
- (fmakunbound 'c-mode)
- (makunbound 'c-mode-map)
- (fmakunbound 'c++-mode)
- (makunbound 'c++-mode-map)
- (makunbound 'c-style-alist)
- (load-library "old-c-mode")
- (load-library "old-c++-mode")
-
- This must be done before any other reference is made to either
-c-mode or c++-mode.

-
-Q5.0.3: How do I get `More' Syntax Highlighting on by default?
---------------------------------------------------------------
-
-Use the following code in your `init.el'/`.emacs':
-
- (setq-default font-lock-maximum-decoration t)
-
- See also `Syntax Highlighting' from the `Options' menu. Remember to
-save options.

-
-Q5.0.4: How can I enable auto-indent and/or Filladapt?
-------------------------------------------------------
-
-Put the following line in your `init.el'/`.emacs':
-
- (setq indent-line-function 'indent-relative-maybe)
-
- If you want to get fancy, try the `filladapt' package available
-standard with XEmacs. Put this into your `init.el'/`.emacs':
-
- (require 'filladapt)
- (setq-default filladapt-mode t)
- (add-hook 'c-mode-hook 'turn-off-filladapt-mode)
-
- This will enable Filladapt for all modes except C mode, where it
-doesn't work well. To turn Filladapt on only in particular major
-modes, remove the `(setq-default ...)' line and use
-`turn-on-filladapt-mode', like this:
-
- (add-hook 'text-mode-hook 'turn-on-filladapt-mode)
-
- You can customize filling and adaptive filling with Customize.
-Select from the `Options' menu `Advanced
-(Customize)->Emacs->Editing->Fill->Fill...' or type `M-x customize
-<RET> fill <RET>'.
-
- Note that well-behaving text-lookalike modes will run
-`text-mode-hook' by default (e.g. that's what Message does). For the
-nasty ones, you'll have to provide the `add-hook's yourself.
-
- Please note that the `fa-extras' package is no longer useful.

-
-Q5.0.5: How can I get XEmacs to come up in text/auto-fill mode by default?
---------------------------------------------------------------------------
-
-Try the following lisp in your `init.el'/`.emacs':
-
- (setq default-major-mode 'text-mode)
- (setq text-mode-hook 'turn-on-auto-fill)
-
- *WARNING*: note that changing the value of `default-major-mode' from
-`fundamental-mode' can break a large amount of built-in code that
-expects newly created buffers to be in `fundamental-mode'. (Changing
-from `fundamental-mode' to `text-mode' might not wreak too much havoc,
-but changing to something more exotic like a lisp-mode would break many
-Emacs packages).
-
- Note that Emacs by default starts up in buffer `*scratch*' in
-`initial-major-mode', which defaults to `lisp-interaction-mode'. Thus
-adding the following form to your Emacs init file will cause the
-initial `*scratch*' buffer to be put into auto-fill'ed `text-mode':
-
- (setq initial-major-mode
- (lambda ()
- (text-mode)
- (turn-on-auto-fill)))
-
- Note that after your init file is loaded, if
-`inhibit-startup-message' is `nil' (the default) and the startup buffer
-is `*scratch*' then the startup message will be inserted into
-`*scratch*'; it will be removed after a timeout by erasing the entire
-`*scratch*' buffer. Keep in mind this default usage of `*scratch*' if
-you desire any prior manipulation of `*scratch*' from within your Emacs
-init file. In particular, anything you insert into `*scratch*' from
-your init file will be later erased. Also, if you change the mode of
-the `*scratch*' buffer, be sure that this will not interfere with
-possible later insertion of the startup message (e.g. if you put
-`*scratch*' into a nonstandard mode that has automatic font lock rules,
-then the startup message might get fontified in a strange foreign
-manner, e.g. as code in some programming language).

-Q5.0.6: How do I start up a second shell buffer?
-------------------------------------------------
-
-In the `*shell*' buffer:
-
- M-x rename-buffer <RET> *shell-1* <RET>
- M-x shell RET
-
- This will then start a second shell. The key is that no buffer named
-`*shell*' can exist. It might be preferable to use `M-x
-rename-uniquely' to rename the `*shell*' buffer instead of `M-x
-rename-buffer'.
-
- Alternately, you can set the variable `shell-multiple-shells'. If
-the value of this variable is non-nil, each time shell mode is invoked,
-a new shell is made

-Q5.0.7: Telnet from shell filters too much
-------------------------------------------
-
-I'm using the Emacs `M-x shell' function, and I would like to invoke
-and use a telnet session within it. Everything works fine except that
-now all `^M''s are filtered out by Emacs. Fixes?
-
- Use `M-x rsh' or `M-x telnet' to open remote sessions rather than
-doing rsh or telnet within the local shell buffer. Starting with
-XEmacs-20.3 you can also use `M-x ssh' to open secure remote session if
-you have `ssh' installed.

-----------------------------------------
-
-We don't know, but you can use tpu-edt emulation instead, which works
-fine and is a little fancier than the standard edt emulation. To do
-this, add the following line to your `init.el'/`.emacs':
-
- (tpu-edt)
-
- If you don't want it to replace `C-h' with an edt-style help menu
-add this as well:

-
- (viper-mode)

-Q5.0.12: How do I disable gnuserv from opening a new frame?
------------------------------------------------------------
-
-If you set the `gnuserv-frame' variable to the frame that should be
-used to display buffers that are pulled up, a new frame will not be
-created. For example, you could put
-
- (setq gnuserv-frame (selected-frame))
-
- early on in your `init.el'/`.emacs', to ensure that the first frame
-created is the one used for your gnuserv buffers.
-
- There is an option to set the gnuserv target to the current frame.
-See `Options->Display->"Other Window" Location->Make Current Frame
-Gnuserv Target'
-
- Starting with XEmacs-20.3 you can also change this with Customize.
-Select from the `Options' menu `Advanced

-`M-x customize <RET> gnuserv <RET>'.

-
-Put the following in your `init.el'/`.emacs' file to start the server:
-
- (gnuserv-start)
-
- Start your first XEmacs as usual. After that, you can do:
-
- gnuclient randomfilename
-
- from the command line to get your existing XEmacs process to open a
-new frame and visit randomfilename in that window. When you're done
-editing randomfilename, hit `C-x #' to kill the buffer and get rid of
-the frame.

-5.1: Emacs Lisp Programming Techniques
-======================================
-
-Q5.1.1: What is the difference in key sequences between XEmacs and GNU Emacs?
------------------------------------------------------------------------------
-
-Erik Naggum <clerik@naggum.no> writes;
-
- Emacs has a legacy of keyboards that produced characters with
- modifier bits, and therefore map a variety of input systems into
- this scheme even today. XEmacs is instead optimized for X events.
- This causes an incompatibility in the way key sequences are
- specified, but both Emacs and XEmacs will accept a key sequence as
- a vector of lists of modifiers that ends with a key, e.g., to bind
- `M-C-a', you would say `[(meta control a)]' in both Emacsen.
- XEmacs has an abbreviated form for a single key, just (meta
- control a). Emacs has an abbreviated form for the Control and the
- Meta modifiers to string-characters (the ASCII characters), as in
- `\M-\C-a'. XEmacs users need to be aware that the abbreviated
- form works only for one-character key sequences, while Emacs users
- need to be aware that the string-character is rather limited.
- Specifically, the string-character can accommodate only 256
- different values, 128 of which have the Meta modifier and 128 of
- which have not. In each of these blocks, only 32 characters have
- the Control modifier. Whereas `[(meta control A)]' differs from
- `[(meta control a)]' because the case differs, `\M-\C-a' and
- `\M-\C-A' do not. Programmers are advised to use the full common
- form, both because it is more readable and less error-prone, and
- because it is supported by both Emacsen.
-
- Another (even safer) way to be sure of the key-sequences is to use
-the `read-kbd-macro' function, which takes a string like `C-c <up>',
-and converts it to the internal key representation of the Emacs you
-use. The function is available both on XEmacs and GNU Emacs.

-Q5.1.2: Can I generate "fake" keyboard events?
-----------------------------------------------
-
-I wonder if there is an interactive function that can generate "fake"
-keyboard events. This way, I could simply map them inside XEmacs.
-
- This seems to work:
-
- (defun cg--generate-char-event (ch)
- "Generate an event, as if ch has been typed"
- (dispatch-event (character-to-event ch)))
-
- ;; Backspace and Delete stuff
- (global-set-key [backspace]
- (lambda () (interactive) (cg--generate-char-event 127)))

-The `read-kbd-macro' function returns the internal Emacs representation
-of a human-readable string (which is its argument). Thus:

- (read-kbd-macro "C-c C-a")
- => [(control ?c) (control ?a)]
-
- (read-kbd-macro "C-c C-. <up>")
- => [(control ?c) (control ?.) up]
-
- In GNU Emacs the same forms will be evaluated to what GNU Emacs
-understands internally--the sequences `"\C-x\C-c"' and `[3 67108910
-up]', respectively.
-
- The exact "human-readable" syntax is defined in the docstring of
-`edmacro-mode'. I'll repeat it here, for completeness.
-
- Format of keyboard macros during editing:
-
- Text is divided into "words" separated by whitespace. Except for
- the words described below, the characters of each word go directly
- as characters of the macro. The whitespace that separates words is
- ignored. Whitespace in the macro must be written explicitly, as in
- `foo <SPC> bar <RET>'.
-
- * The special words `RET', `SPC', `TAB', `DEL', `LFD', `ESC',
- and `NUL' represent special control characters. The words
- must be written in uppercase.
-
- * A word in angle brackets, e.g., `<return>', `<down>', or
- `<f1>', represents a function key. (Note that in the standard
- configuration, the function key `<return>' and the control key
- <RET> are synonymous.) You can use angle brackets on the
- words <RET>, <SPC>, etc., but they are not required there.
-
- * Keys can be written by their ASCII code, using a backslash
- followed by up to six octal digits. This is the only way to
- represent keys with codes above \377.
-
- * One or more prefixes `M-' (meta), `C-' (control), `S-'
- (shift), `A-' (alt), `H-' (hyper), and `s-' (super) may
- precede a character or key notation. For function keys, the
- prefixes may go inside or outside of the brackets: `C-<down>'
- == `<C-down>'. The prefixes may be written in any order:
- `M-C-x' == `C-M-x'.
-
- Prefixes are not allowed on multi-key words, e.g., `C-abc',
- except that the Meta prefix is allowed on a sequence of
- digits and optional minus sign: `M--123' == `M-- M-1 M-2 M-3'.
-
- * The `^' notation for control characters also works: `^M' ==
- `C-m'.
-
- * Double angle brackets enclose command names: `<<next-line>>'
- is shorthand for `M-x next-line <RET>'.
-
- * Finally, `REM' or `;;' causes the rest of the line to be
- ignored as a comment.
-
- Any word may be prefixed by a multiplier in the form of a decimal
- number and `*': `3*<right>' == `<right> <right> <right>', and
- `10*foo' == `foofoofoofoofoofoofoofoofoofoo'.
-
- Multiple text keys can normally be strung together to form a word,
- but you may need to add whitespace if the word would look like one
- of the above notations: `; ; ;' is a keyboard macro with three
- semicolons, but `;;;' is a comment. Likewise, `\ 1 2 3' is four
- keys but `\123' is a single key written in octal, and `< right >'
- is seven keys but `<right>' is a single function key. When in
- doubt, use whitespace.

-Q5.1.4: What is the performance hit of `let'?
----------------------------------------------
-
-In most cases, not noticeable. Besides, there's no avoiding `let'--you
-have to bind your local variables, after all. Some pose a question
-whether to nest `let's, or use one `let' per function. I think because
-of clarity and maintenance (and possible future implementation),
-`let'-s should be used (nested) in a way to provide the clearest code.

-Q5.1.5: What is the recommended use of `setq'?
-----------------------------------------------
-
- * Global variables
-
- You will typically `defvar' your global variable to a default
- value, and use `setq' to set it later.
-
- It is never a good practice to `setq' user variables (like
- `case-fold-search', etc.), as it ignores the user's choice
- unconditionally. Note that `defvar' doesn't change the value of a
- variable if it was bound previously. If you wish to change a
- user-variable temporarily, use `let':
-
- (let ((case-fold-search nil))
- ... ; code with searches that must be case-sensitive
- ...)
-
- You will notice the user-variables by their docstrings beginning
- with an asterisk (a convention).
-
- * Local variables
-
- Bind them with `let', which will unbind them (or restore their
- previous value, if they were bound) after exiting from the `let'
- form. Change the value of local variables with `setq' or whatever
- you like (e.g. `incf', `setf' and such). The `let' form can even
- return one of its local variables.
-
- Typical usage:
-
- ;; iterate through the elements of the list returned by
- ;; `hairy-function-that-returns-list'
- (let ((l (hairy-function-that-returns-list)))
- (while l
- ... do something with (car l) ...
- (setq l (cdr l))))
-
- Another typical usage includes building a value simply to work
- with it.
-
- ;; Build the mode keymap out of the key-translation-alist
- (let ((inbox (file-truename (expand-file-name box)))
- (i 0))
- ... code dealing with inbox ...
- inbox)
-
- This piece of code uses the local variable `inbox', which becomes
- unbound (or regains old value) after exiting the form. The form
- also returns the value of `inbox', which can be reused, for
- instance:
-
- (setq foo-processed-inbox
- (let .....))

-Q5.1.6: What is the typical misuse of `setq' ?
-----------------------------------------------
-
-A typical misuse is probably `setq'ing a variable that was meant to be
-local. Such a variable will remain bound forever, never to be
-garbage-collected. For example, the code doing:
-
- (defun my-function (whatever)
- (setq a nil)
- ... build a large list ...
- ... and exit ...)
-
- does a bad thing, as `a' will keep consuming memory, never to be
-unbound. The correct thing is to do it like this:
-
- (defun my-function (whatever)
- (let (a) ; default initialization is to nil
- ... build a large list ...
- ... and exit, unbinding `a' in the process ...)
-
- Not only is this prettier syntactically, but it makes it possible for
-Emacs to garbage-collect the objects which `a' used to reference.
-
- Note that even global variables should not be `setq'ed without
-`defvar'ing them first, because the byte-compiler issues warnings. The
-reason for the warning is the following:
-
- (defun flurgoze nil) ; ok, global internal variable
- ...
-
- (setq flurghoze t) ; ops! a typo, but semantically correct.
- ; however, the byte-compiler warns.
-
- While compiling toplevel forms:
- ** assignment to free variable flurghoze

-Q5.1.7: I like the `do' form of cl, does it slow things down?
--------------------------------------------------------------
-
-It shouldn't. Here is what Dave Gillespie has to say about cl.el
-performance:
-
- Many of the advanced features of this package, such as `defun*',
- `loop', and `setf', are implemented as Lisp macros. In
- byte-compiled code, these complex notations will be expanded into
- equivalent Lisp code which is simple and efficient. For example,
- the forms
-
- (incf i n)
- (push x (car p))
-
- are expanded at compile-time to the Lisp forms
-
- (setq i (+ i n))
- (setcar p (cons x (car p)))
-
- which are the most efficient ways of doing these respective
- operations in Lisp. Thus, there is no performance penalty for
- using the more readable `incf' and `push' forms in your compiled
- code.
-
- _Interpreted_ code, on the other hand, must expand these macros
- every time they are executed. For this reason it is strongly
- recommended that code making heavy use of macros be compiled. (The
- features labelled "Special Form" instead of "Function" in this
- manual are macros.) A loop using `incf' a hundred times will
- execute considerably faster if compiled, and will also
- garbage-collect less because the macro expansion will not have to
- be generated, used, and thrown away a hundred times.
-
- You can find out how a macro expands by using the `cl-prettyexpand'
- function.

-slowness comes from internal mechanisms such as redisplay, or from the
-fact that it is an interpreter.

-Q5.1.9: How do I put a glyph as annotation in a buffer?
--------------------------------------------------------
-
-Here is a solution that will insert the glyph annotation at the
-beginning of buffer:
-
- (make-annotation (make-glyph '([FORMAT :file FILE]
- [string :data "fallback-text"]))
- (point-min)
- 'text
- (current-buffer))
-
- Replace `FORMAT' with an unquoted symbol representing the format of
-the image (e.g. `xpm', `xbm', `gif', `jpeg', etc.) Instead of `FILE',
-use the image file name (e.g.
-`/usr/local/lib/xemacs-21.4/etc/recycle.xpm').
-
- You can turn this to a function (that optionally prompts you for a

---------------------------------------------------------
-
-I tried to use `map-extents' to do an operation on all the extents in a
-region. However, it seems to quit after processing a random number of
-extents. Is it buggy?
-
- No. The documentation of `map-extents' states that it will iterate
-across the extents as long as FUNCTION returns `nil'. Unexperienced
-programmers often forget to return `nil' explicitly, which results in
-buggy code. For instance, the following code is supposed to delete all
-the extents in a buffer, and issue as many `fubar!' messages.
-
- (map-extents (lambda (ext ignore)
- (delete-extent ext)
- (message "fubar!")))
-
- Instead, it will delete only the first extent, and stop right there -
-because `message' will return a non-nil value. The correct code is:
-
- (map-extents (lambda (ext ignore)
- (delete-extent ext)
- (message "fubar!")
- nil))

-Q5.3.1: How do you make XEmacs indent CL if-clauses correctly?
---------------------------------------------------------------
-
-I'd like XEmacs to indent all the clauses of a Common Lisp `if' the
-same amount instead of indenting the 3rd clause differently from the
-first two.
-
- One way is to add, to `init.el'/`.emacs':
-
- (put 'if 'lisp-indent-function nil)
-
- However, note that the package `cl-indent' that comes with XEmacs
-sets up this kind of indentation by default. `cl-indent' also knows
-about many other CL-specific forms. To use `cl-indent', one can do
-this:
-
- (load "cl-indent")
- (setq lisp-indent-function (function common-lisp-indent-function))
-
- One can also customize `cl-indent.el' so it mimics the default `if'
-indentation `then' indented more than the `else'. Here's how:
-
- (put 'if 'common-lisp-indent-function '(nil nil &body))
-
- Also, a new version (1.2) of `cl-indent.el' was posted to
-comp.emacs.xemacs on 12/9/94. This version includes more documentation
-than previous versions. This may prove useful if you need to customize
-any indent-functions.

-Q5.3.10: How can I get those oh-so-neat X-Face lines?
------------------------------------------------------
-
-Firstly there is an ftp site which describes X-faces and has the
-associated tools mentioned below, at
-`ftp://ftp.cs.indiana.edu:/pub/faces/'.
-
- Then the steps are
-
- 1. Create 48x48x1 bitmap with your favorite tool
-
- 2. Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,
- and then compile the face.
-
- 3. cat file.xbm | xbm2ikon |compface > file.face
-
- 4. Then be sure to quote things that are necessary for emacs strings:
-
- cat ./file.face | sed 's/\\/\\\\/g'
- | sed 's/\"/\\\"/g' > ./file.face.quoted
-
- 5. Then set up emacs to include the file as a mail header - there
- were a couple of suggestions here--either something like:
-
- (setq mail-default-headers
- "X-Face: <Ugly looking text string here>")
-
- Or, alternatively, as:
-
- (defun mail-insert-x-face ()
- (save-excursion
- (goto-char (point-min))
- (search-forward mail-header-separator)
- (beginning-of-line)
- (insert "X-Face:")
- (insert-file-contents "~/.face")))
-
- (add-hook 'mail-setup-hook 'mail-insert-x-face)
-
- However, 2 things might be wrong:
-
- Some versions of pbmtoicon produces some header lines that is not
-expected by the version of compface that I grabbed. So I found I had to
-include a `tail +3' in the pipeline like this:
-
- cat file.xbm | xbm2ikon | tail +3 |compface > file.face
-
- Some people have also found that if one uses the `(insert-file)'
-method, one should NOT quote the face string using the sed script .
-
- It might also be helpful to use Stig's <stig@hackvan.com> script
-(included in the compface distribution at XEmacs.org) to do the
-conversion.

- all Emacsen define it.
-
- 3. Emacs Info looks for a standard `dir' file in each of the
- directories scanned from #1 and magically concatenates them
- together.
-
- 4. XEmacs Info looks for a `localdir' file (which consists of
- just the menu entries from a `dir' file) in each of the
- directories scanned from #1 (except the first), does a simple
- concatenation of them, and magically attaches the resulting
- list to the end of the menu in the `dir' file in the first
- directory.
-
- Another alternative is to convert the documentation to HTML with
- texi2html and read it from a web browser like Lynx or W3.

-Q5.3.12: What do I need to change to make printing work?
---------------------------------------------------------
-
-For regular printing there are two variables that can be customized.
-
-`lpr-command'
- This should be set to a command that takes standard input and sends
- it to a printer. Something like:
-
- (setq lpr-command "lp")
-
-`lpr-switches'
- This should be set to a list that contains whatever the print
- command requires to do its job. Something like:
-
- (setq lpr-switches '("-depson"))
-
- For postscript printing there are three analogous variables to
-customize.
-
-`ps-lpr-command'
- This should be set to a command that takes postscript on standard
- input and directs it to a postscript printer.
-
-`ps-lpr-switches'
- This should be set to a list of switches required for
- `ps-lpr-command' to do its job.
-
-`ps-print-color-p'
- This boolean variable should be set `t' if printing will be done in
- color, otherwise it should be set to `nil'.
-
- NOTE: It is an undocumented limitation in XEmacs that postscript
-printing (the `Pretty Print Buffer' menu item) *requires* a window
-system environment. It cannot be used outside of X11.

-6.0: General Info
-=================
-
-Q6.0.1: What is the status of the XEmacs port to Windows?
----------------------------------------------------------
-
-Is XEmacs really ported to MS Windows? What is the status of the port?
-
- Beginning with release 21.0, XEmacs has worked under MS Windows. A
-group of dedicated developers actively maintains and improves the
-Windows-specific portions of the code. The mailing list at
-<xemacs-nt@xemacs.org> is dedicated to that effort (please use the
--request address to subscribe). (Despite its name, XEmacs actually
-works on all versions of Windows.)
-
- As of May 2001, XEmacs on MS Windows is stable and full-featured, and
-has been so for a year or more - in fact, some features, such as
-printing, actually work better on Windows than native Unix. However,
-the internationalization (Mule) support does not work - although this
-is being actively worked on.

-
-Q6.0.2: What flavors of MS Windows are supported? The list name implies NT only.
----------------------------------------------------------------------------------
-
-The list name is misleading, as XEmacs supports and has been compiled on
-Windows 95, Windows 98, Windows NT, Windows 2000, Windows ME, Windows
-XP, and all newer versions of Windows. The MS Windows-specific code is
-based on Microsoft Win32 API, and will not work on MS Windows 3.x or on
-MS-DOS.
-
- XEmacs also supports the Cygwin and MinGW development and runtime
-environments, where it also uses native Windows code for graphical
-features.

-
-Q6.0.3: Are binaries available?
--------------------------------
-
-Binaries are available at `http://www.xemacs.org/Download/win32/' for
-the native and Cygwin MS Windows versions of 21.4, and the native
-version of 21.1.
-
- The 21.4 binaries use a modified version of the Cygwin installer.
-Run the provided `setup.exe', and follow the instructions.

-
-Q6.0.4: Can I build XEmacs on MS Windows with X support? Do I need to?
------------------------------------------------------------------------
-
-Yes, you can, but no you do not need to. In fact, we recommend that you
-use a native-GUI version unless you have a specific need for an X
-version.

-
-Q6.0.5: I'd like to help out. What do I do?
---------------------------------------------
-
-It depends on the knowledge and time you possess. If you are a
-programmer, try to build XEmacs and see if you can improve it.
-Windows-specific improvements like integration with established Windows
-environments are especially sought after.
-
- Otherwise, you can still help by downloading the binaries, using
-XEmacs as your everyday editor and reporting bugs you find to the
-mailing list.
-
- Another area where we need help is the documentation: We need good
-documentation for building XEmacs and for using it. This FAQ is a
-small step in that direction.

-File: xemacs-faq.info, Node: Q6.0.6, Next: Q6.0.7, Prev: Q6.0.5, Up: MS Windows
-
-Q6.0.6: What are Cygwin and MinGW, and do I need them to run XEmacs?
---------------------------------------------------------------------
-
-To answer the second part of the question: No, you, you don't need
-Cygwin or MinGW to build or to run XEmacs. But if you have them and
-want to use them, XEmacs supports these environments.
-
- (One important reason to support Cygwin is that it lets the MS
-Windows developers test out their code in a Unix environment without
-actually having to have a Unix machine around. For this reason alone,
-Cygwin support is likely to remain supported for a long time in XEmacs.
-Same goes for the X support under Cygwin, for the same reasons. MinGW
-support, on the other hand, depends on volunteers to keep it up to date;
-but this is generally not hard.)
-
- Cygwin is a set of tools providing Unix-like API on top of Win32.
-It makes it easy to port large Unix programs without significant
-changes to their source code. It is a development environment as well
-as a runtime environment.
-
- When built with Cygwin, XEmacs supports all display types - TTY, X &
-Win32 GUI, and can be built with support for all three simultaneously.
-If you build with Win32 GUI support then the Cygwin version uses the
-majority of the Windows-specific code, which is mostly related to
-display. If you want to build with X support you need X libraries (and
-an X server to display XEmacs on); see *Note Q6.1.4::. TTY and Win32
-GUI require no additional libraries beyond what comes standard with
-Cygwin.
-
- The advantages of the Cygwin version are that it integrates well with
-the Cygwin environment for existing Cygwin users; uses configure so
-building with different features is very easy; and actively supports X &
-TTY. Furthermore, the entire Cygwin environment and compiler are free,
-whereas Visual C++ costs money.
-
- The disadvantage is that it requires the whole Cygwin environment,
-whereas the native port requires only a suitable MS Windows compiler.
-Also, it follows the Unix filesystem and process model very closely
-(some will undoubtedly view this as an advantage).
-
- See `http://sources.redhat.com/cygwin/' for more information on
-Cygwin.
-
- MinGW is a collection of header files and import libraries that allow
-one to use GCC under the Cygwin environment to compile and produce
-exactly the same native Win32 programs that you can using Visual C++.
-Programs compiled with MinGW make use of the standard Microsoft runtime
-library `MSVCRT.DLL', present on all Windows systems, and look, feel,
-and act like a standard Visual-C-produced application. (The only
-difference is the compiler.) This means that, unlike a
-standardly-compiled Cygwin application, no extra runtime support (e.g.
-Cygwin's `cygwin1.dll') is required. This, along with the fact that
-GCC is free (and works in a nice Unix-y way in a nice Unix-y
-environment, for those die-hard Unix hackers out there), is the main
-advantage of MinGW. It is also potentially faster than Cygwin because
-it has less overhead when calling Windows, but you lose the POSIX
-emulation layer, which makes Unix programs harder to port. (But this is
-irrelevant for XEmacs since it's already ported to Win32.)
-
- See `http://www.mingw.org/' for more information on MinGW.
-
-\1f
-File: xemacs-faq.info, Node: Q6.0.7, Next: Q6.1.1, Prev: Q6.0.6, Up: MS Windows
-
-Q6.0.7: What exactly are all the different ways to build XEmacs under Windows?
-------------------------------------------------------------------------------
-
-XEmacs can be built in several ways in the MS Windows environment.
-
- The standard way is what we call the "native" port. It uses the
-Win32 API and has no connection with X whatsoever - it does not require
-X libraries to build, nor does it require an X server to run. The
-native port is the most reliable version and provides the best graphical
-support. Almost all development is geared towards this version, and
-there is little reason not to use it.
-
- The second way to build is the Cygwin port. It takes advantage of
-Cygnus emulation library under Win32. *Note Q6.0.6::, for more
-information.
-
- A third way is the MinGW port. It uses the Cygwin environment to
-build but does not require it at runtime. *Note Q6.0.6::, for more
-information.
-
- Finally, you might also be able to build the non-Cygwin, non-MinGW
-"X" port. This was actually the first version of XEmacs that ran under
-MS Windows, and although the code is still in XEmacs, it's essentially
-orphaned and it's unlikely it will compile without a lot of work. If
-you want an MS Windows versin of XEmacs that supports X, use the Cygwin
-version. (The X support there is actively maintained, so that Windows
-developers can test the X support in XEmacs.)

-
-6.1: Building XEmacs on MS Windows
-==================================
-
-Q6.1.1: What compiler/libraries do I need to compile XEmacs?
-------------------------------------------------------------
-
-You need Visual C++ 4.2, 5.0, or 6.0 for the native version. (We have
-some beta testers currently trying to compile with VC.NET, aka version
-7.0, but we can't yet report complete success.) For the Cygwin and MinGW
-versions, you need the Cygwin environment, which comes with GCC, the
-compiler used for those versions. *Note Q6.0.6::, for more information
-on Cygwin and MinGW.

-Please read the file `nt/README' in the XEmacs distribution, which
-contains the full description.

-
-Q6.1.3: What do I need for Cygwin?
-----------------------------------
-
-You can find the Cygwin tools and compiler at:
-
- `http://sources.redhat.com/cygwin/'
-
- Click on the `Install now!' link, which will download a file
-`setup.exe', which you can use to download everything else. (You will
-need to pick a mirror site; `mirrors.rcn.net' is probably the best.)
-You should go ahead and install everything - you'll get various
-ancillary libraries that XEmacs needs or likes, e.g. XPM, PNG, JPEG,
-TIFF, etc.
-
- If you want to compile under X, you will also need the X libraries;
-see *Note Q6.1.6::.
-
- If you want to compile without X, you will need the `xpm-nox'
-library, which must be specifically selected in the Cygwin netinstaller;
-it is not selected by default. The package has had various names.
-Currently it is called `cygXpm-noX4.dll'.
-

-
-Q6.1.4: How do I compile under Cygwin?
---------------------------------------
-
-Similar as on Unix; use the usual `configure' and `make' process. Some
-problems to watch out for:
-
- * make sure HOME is set. This controls where you `init.el'/`.emacs'
- file comes from;
-
- * CYGWIN needs to be set to tty for process support to work, e.g.
- CYGWIN=tty;
-
- * picking up some other grep or other UNIX-like tools can kill
- configure;
-
- * static heap too small, adjust `src/sheap-adjust.h' to a more
- positive number;
-
- * (Unconfirmed) The Cygwin version doesn't understand
- `//machine/path' type paths so you will need to manually mount a
- directory of this form under a unix style directory for a build to
- work on the directory;
-
- * If you're building *WITHOUT* X11, don't forget to change symlinks
- `/usr/lib/libXpm.a' and `/usr/lib/libXpm.dll.a' to point to the
- non-X versions of these libraries. By default they point to the X
- versions. So:
-
- /usr/lib/libXpm.a -> /usr/lib/libXpm-noX.a
- /usr/lib/libXpm.dll.a -> /usr/lib/libXpm-noX.dll.a
-
- (This advice may now be obsolete because of the availability of the
- cygXpm-noX4.dll package from Cygwin. Send confirmation to
- <faq@xemacs.org>.)
-
- * Other problems are listed in the `PROBLEMS' file, in the top-level
- directory of the XEmacs sources.

-
-Q6.1.5: How do I compile using MinGW (aka `the -mno-cygwin flag to gcc')?
--------------------------------------------------------------------------
-
-Similar to the method for Unix. Things to remember:
-
- * Specify the target host on the command line for `./configure', e.g.
- `./configure i586-pc-mingw32'.
-
- * Be sure that your build directory is mounted such that it has the
- same path either as a cygwin path (`/build/xemacs') or as a Windows
- path (`c:\build\xemacs').
-
- * Build `gcc -mno-cygwin' versions of the extra libs, i.e. `libpng',
- `compface', etc.
-
- * Specify the target location of the extra libs on the command line
- to `configure', e.g. `./configure --site-prefixes=/build/libs
- i586-pc-mingw32'.

-
-Q6.1.6: I decided to run with X. Where do I get an X server?
--------------------------------------------------------------
-
-As of May 2001, we are recommending that you use the port of XFree86 to
-Cygwin. This has recently stabilized, and will undoubtedly soon make
-most other MS Windows X servers obsolete. It is what the Windows
-developers use to test the MS Windows X support.
-
- To install, go to `http://xfree86.cygwin.com/'. There is a detailed
-description on that site of exactly how to install it. This
-installation also provides the libraries, include files, and other stuff
-needed for development; a large collection of internationalized fonts;
-the standard X utilities (xterm, twm, etc.) - in a word, the works.
-
- NOTE: As of late May 2001, there is a bug in the file
-`startxwin.bat', used to start X Windows. It passes the option
-`-engine -4' to the X server, which is bogus - you need to edit the
-file and change it to `-engine 4'.

-
-Q6.1.7: How do I compile with X support?
-----------------------------------------
-
-To compile under Cygwin, all you need to do is install XFree86 (*note
-Q6.1.6::). Once installed, `configure' should automatically find the X
-libraries and compile with X support.
-
- As noted above, the non-Cygwin X support is basically orphaned, and
-probably won't work. But if it want to try, it's described in
-`nt/README' in some detail. Basically, you need to get X11 libraries
-from ftp.x.org, and compile them. If the precompiled versions are
-available somewhere, we don't know of it.

-6.2: Customization and User Interface
-=====================================
-
-Q6.2.1: How does the port cope with differences in the Windows user interface?
-------------------------------------------------------------------------------
-
-The XEmacs (and Emacs in general) user interface is pretty different
-from what is expected of a typical MS Windows program. How does the MS
-Windows port cope with it?
-
- As a general rule, we follow native MS Windows conventions as much as
-possible. 21.4 is a fairly complete Windows application, supporting
-native printing, system file dialog boxes, tool tips, etc. In cases
-where there's a clear UI conflict, we currently use normal Unix XEmacs
-behavior by default, but make sure the MS Windows "look and feel" (mark
-via shift-arrow, self-inserting deletes region, Alt selects menu items,
-etc.) is easily configurable (respectively: using the variable
-`shifted-motion-keys-select-region' in 21.4 and above [it's in fact the
-default in these versions], or the `pc-select' package; using the
-`pending-del' package; and setting the variable
-`menu-accelerator-enabled' to `menu-force' in 21.4 and above). In
-fact, if you use the sample `init.el' file as your init file, you will
-get all these behaviors automatically turned on.
-
- In future versions, some of these features might be turned on by
-default in the MS Windows environment.

-
-Q6.2.2: How do I change fonts in XEmacs on MS Windows?
-------------------------------------------------------
-
-In 21.4 and above, you can use the "Options" menu to change the font.
-You can also do it in your init file, e.g. like this:
-
- (set-face-font 'default "Lucida Console:Regular:10")
- (set-face-font 'modeline "MS Sans Serif:Regular:10")

-
-Q6.2.3: Where do I put my `init.el'/`.emacs' file?
---------------------------------------------------
-
-`init.el' is the name of the init file starting with 21.4, and is
-located in the subdirectory `.xemacs/' of your home directory. In
-prior versions, the init file is called `.emacs' and is located in your
-home directory. Your home directory under Windows is determined by the
-`HOME' environment variable. If this is not set, it defaults to `C:\'.
-
- To set this variable, modify `AUTOEXEC.BAT' under Windows 95/98, or
-select `Control Panel->System->Advanced->Environment Variables...'
-under Windows NT/2000.

-Q6.2.4: How do I get Windows Explorer to associate a file type with XEmacs?
----------------------------------------------------------------------------
-
-Associating a new file type with XEmacs.
-........................................
-
-In Explorer select `View/Options/File Types', press `[New Type...]' and
-fill in the dialog box, e.g.:
-
- Description of type: Emacs Lisp source
- Associated extension: el
- Content Type (MIME): text/plain
-
- then press `[New...]' and fill in the `Action' dialog box as follows:
-
- Action:
- Open
-
- Application used to perform action:
- D:\Full\path\for\xemacs.exe "%1"
-
- [x] Use DDE
-
- DDE Message:
- open("%1")

- <leave blank>
-
- DDE Application Not Running:
- <leave blank>
-
- Topic:
- <leave blank>
-
-Associating an existing file type with XEmacs.
-..............................................
-
-In Explorer select `View/Options/File Types'. Click on the file type
-in the list and press `[Edit...]'. If the file type already has an
-`Open' action, double click on it and fill in the `Action' dialog box
-as described above; otherwise create a new action.
-
- If the file type has more than one action listed, you probably want
-to make the `Open' action that you just edited the default by clicking
-on it and pressing `Set Default'.
-
- Note for Windows 2000 users: Under Windows 2000, get to `File Types'
-using `Control Panel->Folder Options->File Types'.

-6.3: Miscellaneous
-==================
-
-Q6.3.1: Does XEmacs rename all the `win32-*' symbols to `w32-*'?
-----------------------------------------------------------------
-
-In his flavor of Emacs 20, Richard Stallman has renamed all the
-`win32-*' symbols to `w32-*'. Does XEmacs do the same?
-
- We consider such a move counter-productive, thus we do not use the
-`w32' prefix. (His rather questionable justification was that he did
-not consider Windows to be a "winning" platform.) However, the name
-`Win32' is not particularly descriptive outside the Windows world, and
-using just `windows-' would be too generic. So we chose a compromise,
-the prefix `mswindows-' for Windows-related variables and functions.
-
- Thus all the XEmacs variables and functions directly related to
-either the Windows GUI or OS are prefixed `mswindows-' (except for a
-couple of debugging variables, prefixed `debug-mswindows-'). From an
-architectural perspective, however, we believe that this is mostly a
-non-issue because there should be a very small number of
-window-systems-specific variables anyway. Whenever possible, we try to
-provide generic interfaces that apply to all window systems.

-
-Q6.3.2: What are the differences between the various MS Windows emacsen?
-------------------------------------------------------------------------
-
-XEmacs, Win-Emacs, DOS Emacs, NT Emacs, this is all very confusing.
-Could you briefly explain the differences between them?
-
- Here is a recount of various Emacs versions running on MS Windows:
-
- * XEmacs
-
- - Beginning with XEmacs 19.12, XEmacs' architecture was
- redesigned in such a way to allow clean support of multiple
- window systems. At this time the TTY support was added,
- making X and TTY the first two "window systems" supported by
- XEmacs. The 19.12 design is the basis for the current native
- MS Windows code.
-
- - Some time during 1997, David Hobley (soon joined by Marc
- Paquette) imported some of the NT-specific portions of GNU
- Emacs, making XEmacs with X support compile under Windows NT,
- and creating the "X" port.
-
- - Several months later, Jonathan Harris sent out initial
- patches to use the Win32 API, thus creating the native port.
- Since then, various people have contributed, including Kirill
- M. Katsnelson (contributed support for menubars, subprocesses
- and network, as well as loads of other code), Andy Piper
- (ported XEmacs to Cygwin environment, contributed Windows
- unexec, Windows-specific glyphs and toolbars code, and more),
- Ben Wing (loads of improvements; primary MS Windows developer
- since 2000), Jeff Sparkes (contributed scrollbars support)
- and many others.
-
- * NT Emacs
-
- - NT Emacs is a version of GNU Emacs modified to compile and
- run under MS Windows 95 and NT using the native Win32 API.
- As such, it is close in spirit to the XEmacs "native" port.
-
- - NT Emacs has been written by Geoff Voelker, and more
- information can be found at
- `http://www.gnu.org/software/emacs/windows/ntemacs.html'.
-
- * Win-Emacs
-
- - Win-Emacs was a port of Lucid Emacs 19.6 to MS Windows using X
- compatibility libraries. Win-Emacs was written by Ben Wing.
- The MS Windows code never made it back to Lucid Emacs, and
- its creator (Pearl Software) has long since gone out of
- business.
-
- * GNU Emacs for DOS
-
- - GNU Emacs features support for MS-DOS and DJGPP (D.J.
- Delorie's DOS port of GCC). Such an Emacs is heavily
- underfeatured, because it does not support long file names,
- lacks proper subprocesses support, and is far too big
- compared with typical DOS editors.
-
- * GNU Emacs compiled with Win32
-
- - Starting with version 19.30, it has been possible to compile
- GNU Emacs under MS Windows using the DJGPP compiler and X
- libraries. The result is very similar to GNU Emacs compiled
- under MS DOS, only it works somewhat better because it runs
- in 32-bit mode, makes use of all the system memory, supports
- long file names, etc.

-
-Q6.3.3: XEmacs 21.1 on Windows used to spawn an ugly console window on every startup. Has that been fixed?
------------------------------------------------------------------------------------------------------------
-
-Yes.
-
- The console was there because `temacs' (and in turn, `xemacs') was a
-console application, and Windows typically creates a new console for a
-console process unless the creating process requests that one isn't
-created. This used to be fixed with `runemacs', a small Windows
-application that existed merely to start `xemacs', stating that it
-didn't want a console.
-
- XEmacs 21.4 fixes this cleanly by the virtue of being a true "GUI"
-application. The explanation of what that means is included for
-educational value.
-
- When building an application to be run in a Win32 environment, you
-must state which sub-system it is to run in. Valid subsystems include
-"console" and "gui". The subsystem you use affects the run time
-libraries linked into your application, the start up function that is
-run before control is handed over to your application, the entry point
-to your program, and how Windows normally invokes your program. (Console
-programs automatically get a console created for them at startup if
-their stdin/stdout don't point anywhere useful, which is the case when
-run from the GUI. This is a stupid design, of course - instead, the
-console should get created only when the first I/O actually occurs!
-GUI programs have an equally stupid design: When called from
-`CMD.EXE'/`COMMAND.COM', their stdin/stdout will be set to point
-nowhere useful, even though the command shell has its own stdin/stdout.
-It's as if someone who had learned a bit about stdio but had no actual
-knowledge of interprocess communication designed the scheme;
-unfortunately, the whole process-communication aspect of the Win32 API
-is equally badly designed.) For example, the entry point for a console
-app is "main" (which is what you'd expect for a C/C++ program), but the
-entry point for a "gui" app is "WinMain". This confuses and annoys a
-lot of programmers who've grown up on Unix systems, where the kernel
-doesn't really care whether your application is a gui program or not.
-
- For reasons not altogether clear, and are lost in the mists of time
-and tradition, XEmacs on Win32 started out as a console application, and
-therefore a console was automatically created for it. (It may have been
-made a console application partly because a console is needed in some
-circumstances, especially under Win95, to interrupt, terminate, or send
-signals to a child process, and because of the bogosity mentioned above
-with GUI programs and the standard command shell. Currently, XEmacs
-just creates and immediately hides a console when necessary, and works
-around the "no useful stdio" problem by creating its own console window
-as necessary to display messages in.)

-Q6.3.4: What is the porting team doing at the moment?
------------------------------------------------------
-
-(as of June 2001)
-
- The porting team is continuing work on the MS Windows-specific code.
-Major projects are the development of Mule (internationalization)
-support for Windows and the improvement of the widget support (better
-support for dialog boxes, buttons, edit fields, and similar UI
-elements).

-
-6.3: Troubleshooting
-====================
-
-Q6.4.1 XEmacs won't start on Windows.
--------------------------------------
-
-XEmacs relies on a process called "dumping" to generate a working
-executable. Under MS-Windows this process effectively fixes the memory
-addresses of information in the executable. When XEmacs starts up it
-tries to reserve these memory addresses so that the dumping process can
-be reversed - putting the information back at the correct addresses.
-Unfortunately some .DLLs (for instance the soundblaster driver) occupy
-memory addresses that can conflict with those needed by the dumped
-XEmacs executable. In this instance XEmacs will fail to start without
-any explanation. Note that this is extremely machine specific.
-
- 21.1.10 includes a fix for this that makes more intelligent guesses
-about which memory addresses will be free, and this should cure the
-problem for most people. 21.4 implements "portable dumping", which
-eliminates the problem altogether. We recommend you use the 21.4
-binaries, but you can use the 21.1 binaries if you are very paranoid
-about stability. *Note Q6.0.3::.

-
-Q6.4.2 Why do I get a blank toolbar on Windows 95?
---------------------------------------------------
-
-You need at least version 4.71 of the system file `comctl32.dll'. The
-updated version is supplied with Internet Explorer 4 and later but if
-you are avoiding IE you can also download it from the Microsoft web
-site. Go into support and search for `comctl32.dll'. The download is
-a self-installing executable.

-
-or "ispell" or other commands that seem related to whatever you just
-tried to do (M-x ediff or M-$, for example).
-
- There are a large number of common (in the sense that "everyone has
-these, they really do") Unix utilities that are not provided with
-XEmacs. The GNU Project's implementations are available for Windows in
-the the Cygwin distribution (`http://www.cygwin.com/'), which also
-provides a complete Unix emulation environment (and thus makes ports of
-Unix utilities nearly trivial). Another implementation is that from

-
-This is part 7 of the XEmacs Frequently Asked Questions list. This

-interesting items that have transpired recently. (But in practice it's
-not getting updated like this.)
-
- This section also contains descriptions of the new features in all
-the recent releases of XEmacs. For the most part, the information
-below is a synopsis of the more complete information that can be found
-in the file `NEWS' in the `etc' directory of the XEmacs distribution.
-You can view this file in XEmacs using `C-h n' or the `Help' menu.

-Q7.0.2: What's new in XEmacs 21.4?
-----------------------------------
-
-21.4 was the "stable" version of the 21.2 series, which was considered
-"experimental" throughout its life; thus there were no "official"
-releases at all. In essence, XEmacs is now following the "alternating"
-scheme of Linux, where at any point there are at least two different
-development branches, one "stable" and one "experimental". Periodic
-releases happen in both branches, but those in the experimental branch
-are not tested as well, and there's no guarantee they will work at all.
-The experiemental branch is open to any and all code that's acceptable
-to the developers; the stable branch, however, is in general limited
-only to bug fixes, and all contributions are carefully reviewed to make
-sure they will increase and not decrease stability.
-
- 21.3 never existed at all; it was decided to follow the Linux scheme
-exactly, where odd-numbered series are experimental and even-numbered
-ones stable.
-
- The following lists summarizes the essential changes made in this
-version. For a fuller list, see the `NEWS' in the `etc' directory of
-the XEmacs distribution, or use `C-h n' or the `Help' menu to view this
-file inside of XEmacs.
-

-
- * XEmacs has been unbundled into constituent installable packages.
-
- * *Other notable changes*: The `Options' menu has been ported to
- Custom; XEmacs now is able to choose X visuals and use private
- colormaps; You can drag the vertical divider of "horizontally"
- (side-by-side) split windows.

-
- * *Package changes*: Many changes to `cc-mode', `gnus', `gnuclient'.
- See `NEWS' for full details.
-
- * *New commands, variables and functions*: `center-to-window-line'
- (like `recenter' but doesn't force a redisplay); variable
- `user-full-name' (customize what your full name looks like in
- mail); `M-x customize-changed-options' (customize options whose
- default values changes because you upgraded your XEmacs); `M-x
- add-log-convert' (converts an old-style ChangeLog buffer to
- new-style); `M-x zap-up-to-char' (like `zap-to-char' but doesn't
- delete the char searched for); commands to store, retrieve and
- increment numbers in registers, useful for macros.
-
- * *Changes to commands, variables, and functions*: `M-x
- query-replace' and friends operate only on the region when it's
- active; `echo-keystrokes' can now be a floating-point number; `M-.'
- searches exact tag matches before inexact ones; function
- `user-full-name' with no arguments returns the var
- `user-full-name'; a prefix arg to `M-:' and `C-h c' inserts the
- result in the current buffer.
-
- * *Other changes*: Under X, new application class `XEmacs';
- byte-compilation of user-specs now works.
-
- * *XEmacs/Mule (internationalization) changes*: Mule support now

- `vertical-divider-line-width', `vertical-divider-spacing';
- specifiers and symbols whose value is a specifier allowed as
- modeline specifications.
-
- * *Frame focus changes*: `focus-follows-mouse' works like FSF,
- prevents any attempt to permanently change the selected frame; new
- function `focus-frame' sets the window system focus a frame; new
- special forms `save-selected-frame' and `with-selected-frame'.
-
- * *Window function changes*: `select-window' now has optional
- argument NORECORD to inhibit recording a buffer change;
- `vertical-motion' now correctly handles optional WINDOW argument
- and has new optional argument PIXELS, to have the returned values
- be in pixels; new function `vertical-motion-pixels'; new functions
- `window-text-area-pixel-{width,height,edges}'; new functions
- `shrink-window-pixels' and `enlarge-window-pixels'; new function

-
- * *Performance*: when the new GNU Malloc aka Doug Lea Malloc is
- available, it will be used (better performance on libc6 Linux
- systems); tracking line-numbers in modeline is now efficient;
- profiling records a call-count of all called functions,
- retrievable through `profile-call-count-results'.
-
- * *Startup and path searching*: code to assemble paths at startup
- rewritten for new package system; new function `split-path' (splits
- by `path-separator'); `Info-default-directory-list' obsolete, use
- `Info-directory-list' instead; site-lisp is deprecated and no
- longer on the load-path by default.

-
-Q7.0.5: What's new in XEmacs 20.3?
-----------------------------------
-
-XEmacs 20.3 was released in November 1997. It contains many bugfixes,
-and a number of new features, including Autoconf 2 based configuration,
-additional support for Mule (Multi-language extensions to Emacs), many
-more customizations, multiple frames on TTY-s, support for multiple info
-directories, an enhanced gnuclient, improvements to regexp matching,
-increased MIME support, and many, many synches with GNU Emacs 20.
-
- The XEmacs/Mule support has been only seriously tested in a Japanese
-locale, and no doubt many problems still remain. The support for
-ISO-Latin-1 and Japanese is fairly strong. MULE support comes at a
-price--about a 30% slowdown from 19.16. We're making progress on
-improving performance and XEmacs 20.3 compiled without Mule (which is
-the default) is definitely faster than XEmacs 19.16.
-
- XEmacs 20.3 is the first non-beta v20 release, and will be the basis
-for all further development.

-Q7.0.6: What's new in XEmacs 20.2?
-----------------------------------
-
-The biggest changes in 20.2 include integration of EFS (the next
-generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
-major mode for editing Tex and LaTeX, and a lot of other stuff). Many
-bugs from 20.0 have been fixed for this release. 20.2 also contains a
-new system for customizing XEmacs options, invoked via `M-x customize'.
-
- XEmacs 20.2 is the development release (20.0 was beta), and is no
-longer considered unstable.

Q1.0.1: What is XEmacs?
-----------------------
- XEmacs is a highly customizable open source text editor and
-application development system. It is protected under the GNU Public
-License and related to other versions of Emacs, in particular GNU
-Emacs. Its emphasis is on modern graphical user interface support and
-an open software development model, similar to Linux. XEmacs has an
-active development community numbering in the hundreds, and runs on
-Windows 95 and NT, Linux and nearly every other version of Unix in
-existence. Support for XEmacs has been supplied by Sun Microsystems,
-University of Illinois, Lucid, ETL/Electrotechnical Laboratory, Amdahl
-Corporation, BeOpen, and others, as well as the unpaid time of a great
-number of individual developers.

--------------------------------------
-
- For a detailed description of the differences between GNU Emacs and
-XEmacs and a detailed history of XEmacs, check out the
- NEWS file (http://www.xemacs.org/About/XEmacsVsGNUemacs.html)
-
- However, here is a list of some of the reasons why we think you might
-consider using it:
-
- * It looks nicer.
-
- * The XEmacs maintainers are generally more receptive to suggestions
- than the GNU Emacs maintainers.
-
- * Many more bundled packages than GNU Emacs.
-
- * Binaries are available for many common operating systems.
-
- * Face support on TTY's.
-
- * A built-in toolbar.
-
- * Better Motif compliance.
-
- * Some internationalization support (including full MULE support, if
- compiled with it).
-
- * Variable-width fonts.
-
- * Variable-height lines.
-
- * Marginal annotations.
-
- * ToolTalk support.
-
- * XEmacs can be used as an Xt widget, and can be embedded within
- another application.
-
- * Horizontal and vertical scrollbars (using real toolkit scrollbars).
-
- * Better APIs (and performance) for attaching fonts, colors, and
- other properties to text.
-
- * The ability to embed arbitrary graphics in a buffer.
-
- * Completely compatible (at the C level) with the Xt-based toolkits.

-Q1.0.5: Why Haven't XEmacs and GNU Emacs Merged?
-------------------------------------------------
+Q1.0.5: Who wrote XEmacs?
+-------------------------
- There are currently irreconcilable differences in the views about
-technical, programming, design and organizational matters between RMS
-and the XEmacs development team which provide little hope for a merge to
-take place in the short-term future.
+XEmacs is the result of the time and effort of many people, and the
+active developers have changed over time. There are two major
+components of the XEmacs effort - writing the code itself and providing
+all the support work (testing the code, releasing beta and final
+versions, handling patches, reading bug reports, maintaining the web
+site, managing the mailing lists, etc. etc.). Neither component would
+work without the other.
- If you have a comment to add regarding the merge, it is a good idea
-to avoid posting to the newsgroups, because of the very heated
-flamewars that often result. Mail your questions to
-<xemacs-beta@xemacs.org> and <bug-gnu-emacs@prep.ai.mit.edu>.
+CODING
+------
-\1f
-File: xemacs-faq.info, Node: Q1.0.6, Next: Q1.0.7, Prev: Q1.0.5, Up: Introduction
+The primary code contributor over the years has been Ben Wing (active
+since late 1992). Between 1991 and 1995, large amounts of coding was
+contributed by Jamie Zawinski and Chuck Thompson. Many other people
+have authored major subsystems or otherwise contributed large amounts of
+code, including Andy Piper, Hrvoje Niksic, Jerry James, Jonathan Harris,
+Kyle Jones, Martin Buchholz, Michael Sperber, Olivier Galibert, Richard
+Mlynarik, Stig, William Perry and plenty of others.
-Q1.0.6: Where can I get help?
------------------------------
+ Primary XEmacs-specific subsystems and their authors:
- Probably the easiest way, if everything is installed, is to use
-Info, by pressing `C-h i', or looking for an Info item on the Help
-Menu. `M-x apropos' can be used to look for particular commands.
+Objects
+ - Conversion from 26-bit to 28-bit pointers and integers,
+ lrecords, lcrecords: Richard Mlynarik, 1994
- For items not found in the manual, try reading this FAQ and reading
-the Usenet group comp.emacs.xemacs.
+ - Conversion to 32-bit pointers and 31-bit integers: Kyle
+ Jones, Martin Buchholz
- If you choose to post to a newsgroup, *please use
-comp.emacs.xemacs*. Please do not post XEmacs related questions to
-gnu.emacs.help.
+ - Portable dumper, object descriptions: Olivier Galibert
- If you cannot post or read Usenet news, there is a corresponding
-mailing list which is available. It can be subscribed to by sending a
-message to <xemacs-request@xemacs.org> with `subscribe' in the body of
-the message. Send to the list at <xemacs@xemacs.org>. list. To
-cancel a subscription, you *must* use the xemacs-request address. Send
-a message with a subject of `unsubscribe' to be removed.

- Both the stable and development versions of XEmacs include

-and Linux systems; work for supporting MULE on Windows operating systems
-is in progress. Binaries compiled without MULE support run faster than

+many Linux distributions, such as Red Hat and SuSE.
- *Note Q1.1.2::.
+ Otherwise, you will need to build XEmacs yourself or get your system
+administrator to do it. Generally, this is not a difficult process

+Q1.2.2: What versions of Unix does XEmacs run on?
+-------------------------------------------------
+
+XEmacs is regularly tested on Linux, Solaris, SunOS, HP/UX, FreeBSD,
+OpenBSD, BSD/OS aka BSDI, Tru64 aka DEC/OSF, SCO5, and probably others.
+It should work on all versions of Unix created in the last 10 years or
+so, perhaps with a bit of work on more obscure platforms to correct
+bit-rot. It uses a sophisticated configuration system to auto-detect
+zillions of features that are implemented differently in different
+versions of Unix, so it will probably work on your vendor's version,
+possibly with a bit of tweaking, even if we've never heard of it.
+
+ For problems with particular machines and versions of Unix, see the
+`PROBLEMS' file.
+
+ Much effort has gone into making XEmacs work on as many different
+machines, configurations, and compilers as possible.
+
+ Much effort has gone into making XEmacs 64-bit clean.
+
+ Much effort has gone into removing system-specific code, and
+replacing such code with autodetection at configure time.
+
+ The XEmacs core should build "out of the box" on most Unix-like
+systems.
+
+ XEmacs 21.2 was tested and `make check' succeeded on these Unix
+configurations as of 2001-02-10:
+
+ alphaev56-dec-osf4.0e (both Compaq C and gcc)
+ i386-unknown-freebsd4.2
+ i386-unknown-netbsdelf1.5
+ i586-sco-sysv5uw7.0.1 (both SCO's cc and gcc)
+ i686-pc-linux-gnu
+ hppa2.0-hp-hpux10.20 (both HP's ANSI cc and gcc)
+ mips-sgi-irix6.5 (both MIPSpro cc and gcc)
+ rs6000-ibm-aix4.3.0.0 (both IBM's xlc and gcc)
+ sparc-sun-solaris2.6 (both Sun's Forte C and gcc)
+ sparc-sun-solaris2.7 (both Sun's Forte C and gcc)
+ sparc-sun-sunos4.1.4 (gcc)
+
+ Some systems have a dual mode 32-bit/64-bit compiler. On most of
+these, XEmacs requires the `--pdump' (in XEmacs 21.5, `--enable-pdump')
+configure option to build correctly with the 64-bit version of the
+compiler.
- Original Mule supports the following input methods: Wnn4, Wnn6,
- Canna, SJ3 and XIM. Interfaces for Wnn and SJ3 uses the `egg' user
- interface. Interface for Canna does not use `egg'. I don't know
- about XIM. It is to support ATOK, of course, it may work for
- another servers.
-
- Wnn supports Japanese, Chinese and Korean. It is made by OMRON and
- Kyôto university. It is a powerful and complex system. Wnn4 is
- free and Wnn6 is not free.
-
- Canna supports only Japanese. It is made by NEC. It is a simple and
- powerful system. Canna uses only grammar (Wnn uses grammar and
- probability between words), so I think Wnn is cleverer than Canna,
- however Canna users made a good grammar and dictionary. So for
- standard modern Japanese, Canna seems cleverer than Wnn4. In
- addition, the UNIX version of Canna is free (now there is a
- Microsoft Windows version).
-
- SJ3 supports only Japanese. It is made by Sony. XIM supports was
- made to use ATOK (a major input method in personal computer
- world). XIM is the standard for accessing input methods bundled
- in Japanese versions of Solaris. (XEmacs 20 will support XIM
- input).
-
- Egg consists of following parts:
-
- 1. Input character Translation System (ITS) layer. It
- translates ASCII inputs to Kana/PinYin/Hangul characters.
-
- 2. Kana/PinYin/Hangul to Kanji transfer layer. It is interface
- layer for network Kana-Kanji server (Wnn and Sj3).
-
- These input methods are modal, namely there are mode, alphabet
- mode and Kana-Kanji transfer mode. However there are mode-less
- input methods for Egg and Canna. `Boiled-egg' is a mode-less
- input method running on Egg. For Canna, `canna.el' has a tiny
- boiled-egg like command, `(canna-boil)', and there are some
- boiled-egg like utilities. In addition, it was planned to make an
- abstraction for all transfer type input methods. However authors
- of input methods are busy, so maybe this plan is stopped. Perhaps
- after Mule merged GNU Emacs will be released, it will be continued.

+Q1.2.3: Is there a port of XEmacs to Microsoft Windows?
+-------------------------------------------------------
+
+Yes. Beginning with release 21.0, XEmacs has worked under MS Windows
+and is fully-featured and actively developed. A group of dedicated
+developers actively maintains and improves the Windows-specific
+portions of the code. Some of the core developers, in fact, use
+Windows as their only development environment, and some features, such
+as printing, actually work better on Windows than native Unix and Mac
+OS X. The mailing list at <xemacs-winnt@xemacs.org> is dedicated to
+that effort (please use the -request address to subscribe). (Despite
+its name, XEmacs actually works on all versions of Windows.)
+
+ The list name is misleading, as XEmacs supports and has been
+compiled on Windows 95, Windows 98, Windows NT, Windows 2000, Windows
+ME, Windows XP, and all newer versions of Windows. The MS
+Windows-specific code is based on Microsoft Win32 API, and will not
+work on MS Windows 3.x or on MS-DOS.
+
+ XEmacs also supports the Cygwin and MinGW development and runtime
+environments, where it also uses native Windows code for graphical
+features. In addition, under Cygwin it is possible to compile XEmacs
+to use an X server (and XFree86 is available as part of the standard
+Cygwin installation).

+
+Q1.2.5: What are Cygwin and MinGW, and do I need them to run XEmacs?
+--------------------------------------------------------------------
+
+To answer the second part of the question: No, you, you don't need
+Cygwin or MinGW to build or to run XEmacs. But if you have them and
+want to use them, XEmacs supports these environments.
+
+ (One important reason to support Cygwin is that it lets the MS
+Windows developers test out their code in a Unix environment without
+actually having to have a Unix machine around. For this reason alone,
+Cygwin support is likely to remain supported for a long time in XEmacs.
+Same goes for the X support under Cygwin, for the same reasons. MinGW
+support, on the other hand, depends on volunteers to keep it up to date;
+but this is generally not hard.)
+
+ Cygwin is a set of tools providing Unix-like API on top of Win32.
+It makes it easy to port large Unix programs without significant
+changes to their source code. It is a development environment as well
+as a runtime environment.
+
+ When built with Cygwin, XEmacs supports all display types - TTY, X &
+Win32 GUI, and can be built with support for all three simultaneously.
+If you build with Win32 GUI support then the Cygwin version uses the
+majority of the Windows-specific code, which is mostly related to
+display. If you want to build with X support you need X libraries (and
+an X server to display XEmacs on); see *Note Q2.3.7::. TTY and Win32
+GUI require no additional libraries beyond what comes standard with
+Cygwin.
+
+ The advantages of the Cygwin version are that it integrates well with
+the Cygwin environment for existing Cygwin users; uses configure so
+building with different features is very easy; and actively supports X &
+TTY. Furthermore, the entire Cygwin environment and compiler are free,
+whereas Visual C++ costs money.
+
+ The disadvantage is that it requires the whole Cygwin environment,
+whereas the native port requires only a suitable MS Windows compiler.
+Also, it follows the Unix filesystem and process model very closely
+(some will undoubtedly view this as an advantage).
+
+ See `http://www.cygwin.com/' for more information on Cygwin.
+
+ MinGW is a collection of header files and import libraries that allow
+one to use GCC under the Cygwin environment to compile and produce
+exactly the same native Win32 programs that you can using Visual C++.
+Programs compiled with MinGW make use of the standard Microsoft runtime
+library `MSVCRT.DLL', present on all Windows systems, and look, feel,
+and act like a standard Visual-C-produced application. (The only
+difference is the compiler.) This means that, unlike a
+standardly-compiled Cygwin application, no extra runtime support (e.g.
+Cygwin's `cygwin1.dll') is required. This, along with the fact that
+GCC is free (and works in a nice Unix-y way in a nice Unix-y
+environment, for those die-hard Unix hackers out there), is the main
+advantage of MinGW. It is also potentially faster than Cygwin because
+it has less overhead when calling Windows, but you lose the POSIX
+emulation layer, which makes Unix programs harder to port. (But this is
+irrelevant for XEmacs since it's already ported to Win32.)
+
+ See `http://www.mingw.org/' for more information on MinGW.

- I have the following suggestions about dealing with mule variants:
+Q1.2.6: What are the differences between the various MS Windows emacsen?
+------------------------------------------------------------------------
- * `(featurep 'mule)' `t' on all mule variants
+XEmacs, Win-Emacs, DOS Emacs, NT Emacs, this is all very confusing.
+Could you briefly explain the differences between them?
- * `(boundp 'MULE)' is `t' on only MULE. Maybe the next version
- of Emacs will not have this symbol.
+ Here is a recount of various Emacs versions running on MS Windows:
- * MULE has a variable `mule-version'. Perhaps the next version
- of Emacs will have this variable as well.
+ * XEmacs
- Following is a sample to distinguish mule variants:
+ - Beginning with XEmacs 19.12, XEmacs' architecture was
+ redesigned in such a way to allow clean support of multiple
+ window systems. At this time the TTY support was added,
+ making X and TTY the first two "window systems" supported by
+ XEmacs. The 19.12 design is the basis for the current native
+ MS Windows code.
+
+ - Some time during 1997, David Hobley (soon joined by Marc
+ Paquette) imported some of the NT-specific portions of GNU
+ Emacs, making XEmacs with X support compile under Windows NT,
+ and creating the "X" port.
+
+ - Several months later, Jonathan Harris sent out initial
+ patches to use the Win32 API, thus creating the native port.
+ Since then, various people have contributed, including Kirill
+ M. Katsnelson (contributed support for menubars, subprocesses
+ and network, as well as loads of other code), Andy Piper
+ (ported XEmacs to Cygwin environment, contributed Windows
+ unexec, Windows-specific glyphs and toolbars code, and more),
+ Ben Wing (loads of improvements; primary MS Windows developer
+ since 2000), Jeff Sparkes (contributed scrollbars support)
+ and many others.
+
+ * NT Emacs
+
+ - NT Emacs was an early version of GNU Emacs 19 modified to
+ compile and run under MS Windows 95 and NT using the native
+ Win32 API. It was written by Geoff Voelker, and has long
+ since been incorporated into the mainline GNU Emacs
+ distribution.
+
+ * Win-Emacs
+
+ - Win-Emacs was a port of Lucid Emacs 19.6 to MS Windows using X
+ compatibility libraries. Win-Emacs was written by Ben Wing.
+ The MS Windows code never made it back to Lucid Emacs, and
+ its creator (Pearl Software) has long since gone out of
+ business.
+
+ * GNU Emacs for DOS
+
+ - GNU Emacs features support for MS-DOS and DJGPP (D.J.
+ Delorie's DOS port of GCC). Such an Emacs is heavily
+ underfeatured, because it does not support long file names,
+ lacks proper subprocesses support, and is far too big
+ compared with typical DOS editors.
+
+ * GNU Emacs compiled with Win32
+
+ - Starting with GNU Emacs 19.30, it has been possible to
+ compile GNU Emacs under MS Windows using the DJGPP compiler
+ and X libraries. The result is very similar to GNU Emacs
+ compiled under MS DOS, only it works somewhat better because
+ it runs in 32-bit mode, makes use of all the system memory,
+ supports long file names, etc.

+Q1.2.7: How does the port cope with differences in the Windows user interface?
+------------------------------------------------------------------------------
+
+The XEmacs (and Emacs in general) user interface is pretty different
+from what is expected of a typical MS Windows program. How does the MS
+Windows port cope with it?
+
+ As a general rule, we follow native MS Windows conventions as much as
+possible. 21.4 is a fairly complete Windows application, supporting
+native printing, system file dialog boxes, tool tips, etc. In cases
+where there's a clear UI conflict, we currently use normal Unix XEmacs
+behavior by default, but make sure the MS Windows "look and feel" (mark
+via shift-arrow, self-inserting deletes region, Alt selects menu items,
+etc.) is easily configurable (respectively: using the variable
+`shifted-motion-keys-select-region' in 21.4 and above [it's in fact the
+default in these versions], or the `pc-select' package; using the
+`pending-del' package; and setting the variable
+`menu-accelerator-enabled' to `menu-force' in 21.4 and above). In
+fact, if you use the sample `init.el' file as your init file, you will
+get all these behaviors automatically turned on.
+
+ In future versions, some of these features might be turned on by
+default in the MS Windows environment.

+
+Q1.4.1: Where can I get help?
+-----------------------------
+
+Probably the easiest way, if everything is installed, is to use Info, by
+pressing `C-h i', or looking for an Info item on the Help Menu. `M-x
+apropos' can be used to look for particular commands.
+
+ For items not found in the manual, try reading this FAQ and reading
+the Usenet group comp.emacs.xemacs.
+
+ If you choose to post to a newsgroup, *please use
+comp.emacs.xemacs*. Please do not post XEmacs related questions to
+gnu.emacs.help.
+
+ If you cannot post or read Usenet news, there is a corresponding
+mailing list <xemacs-news@xemacs.org> which is available. It can be
+subscribed to via the Mailman Web interface or by sending mail to to
+<xemacs-news-request@xemacs.org> with `subscribe' in the body of the
+message. See also `http://www.xemacs.org/Lists/#xemacs-news'. To
+cancel a subscription, you may use the <xemacs-news-request@xemacs.org>
+address or the Web interface. Send a message with a subject of
+`unsubscribe' to be removed.

+
+Q1.4.2: Which mailing lists are there?
+--------------------------------------
+
+For complete, up-to-date info on the lists and how to subscribe, see
+`http://www.xemacs.org/Lists/'.
+
+`comp.emacs.xemacs'
+ is a Usenet newsgroup for XEmacs users to discuss problems and
+ issues that arise for them. It's not generally an appropriate
+ place to ask about apparent bugs (use `xemacs-beta'), or future
+ plans (use `xemacs-design').
+
+`xemacs-announce'
+ is a read-only, low volume list for announcements concerning the
+ XEmacs project and new releases of the XEmacs software.
+
+`xemacs-beta'
+ is an open list for bug reports about beta versions of XEmacs.
+ This includes the bug reports themselves, by both users and
+ developers, as well as queries, follow-ups, and discussions
+ further determining their nature and status. This is the primary
+ channel for this kind of discussion; related code changes will
+ usually not be applied until they have been discussed here. When
+ such discussions touch on significant changes to the code (in
+ particular, structural changes), or on changes to API's or
+ external functionality, they should be moved to `xemacs-design'.
+ Requests and proposals for non-bug-related changes do not belong
+ on `xemacs-beta', and should be sent to `xemacs-design' instead.
+
+`xemacs-beta-ja'
+ is an open list for bug reports and design discussion related to
+ Mule features, including Japanese handling, in beta versions of
+ XEmacs. Japanese is the preferred language of discussion. For
+ most timely presentation to reviewers, please consider sending
+ appropriate discussion to `xemacs-mule' or `xemacs-design' in
+ English when convenient for the participants in discussion. When
+ possible, bug reports not related to Mule (including Japanese)
+ should be reported on `xemacs-beta' in English.
+
+`xemacs-buildreports'
+ is an open list for submission of build-reports on beta versions
+ of XEmacs. For information on what the build-reports should
+ contain, please see the `etc/BETA' file which is included in each
+ beta distribution.
+
+`xemacs-cvs'
+ is a read-only list for notices and information on what has been
+ committed to the XEmacs CVS trees, by whom, and for what.
+
+`xemacs-design'
+ is an open list for discussing the design of XEmacs. This
+ includes discussion about planned and ongoing changes to
+ functionality and API changes and additions as well as requests
+ for them. This is the primary channel for this kind of
+ discussion; related code changes will usually not be applied until
+ they have been discussed here. This does not include bug reports,
+ which go to `xemacs-beta'.
+
+`xemacs-mule'
+ is an open mailing list for discussion of International extensions
+ to XEmacs including Mule, XIM, I18n issues, etc, and is not
+ confined to developmental issues. This list is not restricted to
+ English, postings in all languages are welcome.
+
+`xemacs-news'
+ is an open list for discussion and bug reporting for XEmacs. This
+ mailing list is bi-directionally gatewayed with the USENET
+ newsgroup comp.emacs.xemacs.
+
+`xemacs-nt'
+ is a developers-only mailing list and is intended for people who
+ wish to work actively on the porting of XEmacs to Microsoft
+ Windows NT and Microsoft Windows '95.
+
+`xemacs-patches'
+ is an open, moderated list for submission of patches to the XEmacs
+ distribution and its packages. Anyone may subscribe or submit to
+ xemacs-patches, but all submissions are reviewed by the list
+ moderator before they are distributed to the list. Discussion is
+ not appropriate on xemacs-patches.
+
+`xemacs-users-ja'
+ is an open list for discussion and bug reporting for XEmacs.
+ Japanese is the preferred language of discussion. It is not gated
+ to comp.emacs.xemacs or the `xemacs' list. For fastest response,
+ bugs not specifically related to Japanese or Mule features should
+ be reported on `xemacs-beta' (in English).
+
+`xemacs-users-ru'
+ is an open list for discussion and bug reporting for XEmacs.
+ Russian is the preferred language of discussion. It is not gated
+ to comp.emacs.xemacs or the `xemacs' list. For fastest response,
+ bugs not specifically related to Russian or Mule features should
+ be reported on `xemacs-beta' (in English).

+
+ Emacs Info and XEmacs Info do many things differently. If you're
+ trying to support a number of versions of Emacs, here are some
+ notes to remember:
+
+ 1. Emacs Info scans `Info-directory-list' from right-to-left
+ while XEmacs Info reads it from left-to-right, so append to
+ the _correct_ end of the list.
+
+ 2. Use `Info-default-directory-list' to initialize
+ `Info-directory-list' _if_ it is available at startup, but not
+ all Emacsen define it.
+
+ 3. Emacs Info looks for a standard `dir' file in each of the
+ directories scanned from #1 and magically concatenates them
+ together.
+
+ 4. XEmacs Info looks for a `localdir' file (which consists of
+ just the menu entries from a `dir' file) in each of the
+ directories scanned from #1 (except the first), does a simple
+ concatenation of them, and magically attaches the resulting
+ list to the end of the menu in the `dir' file in the first
+ directory.
+
+ Another alternative is to convert the documentation to HTML with
+ texi2html and read it from a web browser like Lynx or W3.

+File: xemacs-faq.info, Node: Q1.5.4, Next: Q1.5.5, Prev: Q1.5.3, Up: Introduction
+
+Q1.5.4: How do I get started developing XEmacs?
+-----------------------------------------------
+
+First, get yourself set up under CVS so that you can access the CVS
+repositories containing the XEmacs sources and the XEmacs packages.
+
+ Next, set up your layout. This is important, as a good layout will
+facilitate getting things done efficiently, while a bad layout will
+could lead to disaster, as you can't figure out which code is the most
+recent, which can be thrown away, etc. We suggest the following
+layout: (feel free to make changes)
+
+ * Everything goes under `/src/xemacs' (use a different directory if
+ you want). From now, instead of saying `/src/xemacs', we use
+ `<xsrc-top>', to make it easier in case someone picked a different
+ directory.
+
+ * Package source is in `<xsrc-top>/package-src'.
+
+ * Installed packages go under `<xsrc-top>/xemacs-packages', and
+ `<xsrc-top>/mule-packages'.
+
+ * A "workspace" is a complete copy of the sources, in which you do
+ work of a particular kind. Workspaces can be differentiated by
+ which branch of the source tree they extend off of - usually
+ either the stable or experimental, unless other branches have been
+ created (for example, Ben created a branch for his Mule work
+ because (1) the project was long-term and involved an enormous
+ number of changes, (2) people wanted to be able to look at what
+ his work in progress, and (3) he wanted to be able to check things
+ in and in general use source-code control, since it was a
+ long-term project). Workspaces are also differentiated in what
+ their purpose is - general working workspace, workspace for
+ particular projects, workspace keeping the latest copy of the code
+ in one of the branches without mods, etc.
+
+ * Various workspaces are subdirectories under `<xsrc-top>', e.g.:
+
+ * `<xsrc-top>/working' (the workspace you're actively working
+ on, periodically synched up with the latest trunk)
+
+ * `<xsrc-top>/stable' (for making changes to the stable version
+ of XEmacs, which sits on a branch)
+
+ * `<xsrc-top>/unsigned-removal' (a workspace for a specific,
+ difficult task that's going to affect lots of source and take
+ a long time, and so best done in its own workspace without
+ the interference of other work you're doing. Also, you can
+ commit just this one large change, separate from all the
+ other changes).
+
+ * `<xsrc-top>/latest' (a copy of the latest sources on the
+ trunk, i.e. the experimental version of XEmacs, with no
+ patches in it; either update it periodically, by hand, or set
+ up a cron job to do it automatically). Set it up so it can
+ be built, and build it so you have a working XEmacs.
+ (Building it might also go into the cron job.)
+
+ This workspace serves a number of purposes:
+ 1. You always have a recent version of XEmacs you can
+ compare against when something you're working on breaks.
+ It's true that you can do this with cvs diff, but when
+ you need to do some serious investigation, this method
+ just fails.
+
+ 2. You (almost) always have a working, up-to-date
+ executable that can be used when your executable is
+ crashing and you need to keep developing it, or when you
+ need an `xemacs' to build packages, etc.
+
+ 3. When creating new workspaces, you can just copy the
+ `latest' workspace using GNU `cp -a'. You have all the
+ .elc's built, everything else probably configured, any
+ spare files in place (e.g. some annoying xpm.dll under
+ Windows, etc.).
+
+ * `<xsrc-top>/latest-stable/' (equivalent to
+ `<xsrc-top>/latest/', but for the Stable branch of XEmacs,
+ rather than the Experimental branch of XEmacs). This may or
+ may not be necessary depending on how much development you do
+ of the stable branch.
+
+ * `<xsrc-top>/xemacsweb' is a workspace for working on the XEmacs
+ web site.
+
+ * `<xsrc-top>/in-patches' for patches received from email and saved
+ to files.
+
+ * `<xsrc-top>/out-patches' for locally-generated patches to be sent
+ to <xemacs-patches@xemacs.org>. Less useful now that the patcher
+ util has been developed.
+
+ * `<xsrc-top>/build', for build trees when compiling and testing
+ XEmacs with various configuration options turned off and on. The
+ scripts in xemacs-builds/ben (see below) can be used to automate
+ building XEmacs workspaces with many different configuration
+ options and automatically filtering out the normal output so that
+ you see only the abnormal output.
+
+ * `<xsrc-top>/xemacs-builds', for the xemacs-builds module, which
+ you need to check out separately in CVS. This contains scripts
+ used for building XEmacs, automating and simplifying using CVS,
+ etc. Under various people's directories are their own build and
+ other scripts. The currently most-maintained scripts are under
+ ben/, where there are easily configurable scripts that can be used
+ to easily build any workspace (esp. if you've more or less
+ followed the layout presented above) unattended, with one or more
+ configuration states (there's a pre-determined list of the most
+ useful, but it's easy to change). The output is filtered and
+ split up in various ways so that you can identify which output
+ came from where, and you can see the output either full or with
+ all "normal" output except occasional status messages filtered so
+ that you only see the abnormal ones.

+
+Q1.5.5: What's the basic layout of the code?
+--------------------------------------------
+
+The file `configure' is a shell script to acclimate XEmacs to the
+oddities of your processor and operating system. It will create a file
+named `Makefile' (a script for the `make' program), which helps
+automate the process of building and installing emacs. See INSTALL for
+more detailed information.
+
+ The file `configure.in' is the input used by the autoconf program to
+construct the `configure' script. Since XEmacs has configuration
+requirements that autoconf can't meet, `configure.in' uses an unholy
+marriage of custom-baked configuration code and autoconf macros; it may
+be wise to avoid rebuilding `configure' from `configure.in' when
+possible.
+
+ The file `Makefile.in' is a template used by `configure' to create
+`Makefile'.
+
+ There are several subdirectories:
+
+ 1. `src' holds the C code for XEmacs (the XEmacs Lisp interpreter and
+ its primitives, the redisplay code, and some basic editing
+ functions).
+
+ 2. `lisp' holds the XEmacs Lisp code for XEmacs (most everything
+ else).
+
+ 3. `lib-src' holds the source code for some utility programs for use
+ by or with XEmacs, like movemail and etags.
+
+ 4. `etc' holds miscellaneous architecture-independent data files
+ XEmacs uses, like the tutorial text. The contents of the `lisp',
+ `info' and `man' subdirectories are architecture-independent too.
+
+ 5. `lwlib' holds the C code for the X toolkit objects used by XEmacs.
+
+ 6. `info' holds the Info documentation tree for XEmacs.
+
+ 7. `man' holds the source code for the XEmacs online documentation.
+
+ 8. `nt' holds files used compiling XEmacs under Microsoft Windows.

+1.6: Politics (XEmacs vs. GNU Emacs)
+====================================
+
+\1f
+File: xemacs-faq.info, Node: Q1.6.1, Next: Q1.6.2, Prev: Q1.5.5, Up: Introduction
+
+Q1.6.1: What is GNU Emacs?
+--------------------------
+
+GNU Emacs and XEmacs are related open-source text editors. Both derive
+from GNU Emacs version 18; the split between the two happened in 1991
+(for comparison, the oldest versions of GNU Emacs date from 1984). For
+information on GNU Emacs, see
+`http://www.gnu.org/software/emacs/emacs.html'.
+
+\1f
+File: xemacs-faq.info, Node: Q1.6.2, Next: Q1.6.3, Prev: Q1.6.1, Up: Introduction
+
+Q1.6.2: How does XEmacs differ from GNU Emacs?
+----------------------------------------------
+
+For a detailed description of the differences between GNU Emacs and
+XEmacs and a detailed history of XEmacs, check out the
+ NEWS file (http://www.xemacs.org/About/XEmacsVsGNUemacs.html)
+
+*User-Visible Editing Features*
+ XEmacs in general tries hard to conform to exist user-interface
+ standards, and to work "out-of-the-box" without the need for
+ obscure customization changes. GNU Emacs, particularly version
+ 21, has gotten better about this (in many cases by copying the
+ XEmacs behavior!), but still has some weirdnesses. For example,
+ the standard method of selecting text using the Shift key works
+ out-of-the-box in XEmacs.
+
+ XEmacs has a built-in toolbar. Four toolbars can actually be
+ configured simultaneously: top, bottom, left, and right toolbars.
+
+ XEmacs has vertical and horizontal scrollbars. Unlike in GNU Emacs
+ 19 (which provides a primitive form of vertical scrollbar), these
+ are true toolkit scrollbars. A look-alike Motif scrollbar is
+ provided for those who don't have Motif. (Even for those who do,
+ the look-alike may be preferable as it is faster.)
+
+ XEmacs has buffer tabs along the top of the frame (although the
+ position can be changed) that make it very easy to switch buffers.
+
+ The menubar under XEmacs is better-designed, with more thought put
+ into it.
+
+ XEmacs can ask questions using popup dialog boxes. Any command
+ executed from a menu will ask yes/no questions with dialog boxes,
+ while commands executed via the keyboard will use the minibuffer.
+
+ XEmacs under MS Windows provides uses the standard file-dialog box
+ for opening and saving files. Standard menu-accelerator behavior
+ can easily be enabled using the Options menu, and integrates well
+ into the existing keymap.
+
+ XEmacs has (still experimental) support for widgets of various
+ sorts - buttons, text boxes, sliders, progress bars, etc. A
+ progress bar is used in font lock to show the progress.
+
+ Experimental support for drag-and-drop protocols is provided from
+ XEmacs 21.
+
+*General Platform Support*
+ If you're running on a machine with audio hardware, you can specify
+ sound files for XEmacs to play instead of the default X beep. See
+ the documentation of the function load-sound-file and the variable
+ sound-alist. XEmacs also supports the network sound protocols NAS
+ and EsounD.
+
+ XEmacs 21 supports database protocols with LISP bindings, currently
+ including Berkeley DB, LDAP, and PostgreSQL (21.2 only).
+
+ XEmacs 20 and 21 support the Canna, Wnn, and SJ3 Japanese input
+ method servers directly, as well as through the X Input Method
+ (XIM) protocol. GNU Emacs 20 supports only the XIM protocol. Both
+ Emacsen support the Quail family of input methods (implemented in
+ LISP) for many languages.
+
+ XEmacs provides support for ToolTalk on systems that have it.
+
+*Packaged LISP Libraries*
+ Many more packages are provided standard with XEmacs than with GNU
+ Emacs 19 or 20.
+
+ XEmacs 21 supports an integrated package management system which
+ uses EFS to download, then automatically install prebuilt LISP
+ libraries. This allows XEmacs users much more straightforward
+ access to the "latest and greatest" version of any given library.
+
+ We are working on a standard method for enabling, disabling and
+ otherwise controlling packages, which should make them very easy
+ to use.
+
+*LISP Programming*
+ From XEmacs 20 on, characters are a separate type. Characters can
+ be converted to integers (and many integers can be converted to
+ characters), but characters are not integers. GNU Emacs 19, XEmacs
+ 19, Mule 2.3 (an extensive patch to GNU Emacs 18.55 and 19.x), and
+ GNU Emacs 20 (incorporating Mule 3 and later Mule 4) represent
+ them as integers.
+
+ From XEmacs 20 on, the buffer is treated as an array of
+ characters, and the representation of buffer text is not exposed
+ to LISP. The GNU Emacs 20 functions like buffer-as-multibyte are
+ not supported.
+
+ In XEmacs, events are first-class objects. GNU Emacs 19 represents
+ them as integers, which obscures the differences between a key
+ gesture and the ancient ASCII code used to represent a particular
+ overlapping subset of them.
+
+ In XEmacs, keymaps are first-class opaque objects. GNU Emacs 19
+ represents them as complicated combinations of association lists
+ and vectors. If you use the advertised functional interface to
+ manipulation of keymaps, the same code will work in XEmacs, GNU
+ Emacs 18, and GNU Emacs 19; if your code depends on the underlying
+ implementation of keymaps, it will not.
+
+ XEmacs uses "extents" to represent all non-textual aspects of
+ buffers; GNU Emacs 19 uses two distinct objects, "text properties"
+ and "overlays", which divide up the functionality between them.
+ Extents are a superset of the union of the functionality of the
+ two GNU Emacs data types. The full GNU Emacs 19 interface to text
+ properties and overlays is supported in XEmacs (with extents being
+ the underlying representation).
+
+ Extents can be made to be copied into strings, and then restored,
+ by kill and yank. Thus, one can specify this behavior on either
+ "extents" or "text properties", whereas in GNU Emacs 19 text
+ properties always have this behavior and overlays never do.
+
+*Window System Programming Interface*
+ XEmacs uses the MIT "Xt" toolkit instead of raw Xlib calls, which
+ makes it be a more well-behaved X citizen (and also improves
+ portability). A result of this is that it is possible to include
+ other Xt "Widgets" in the XEmacs window. Also, XEmacs understands
+ the standard Xt command-line arguments.
+
+ XEmacs supports Motif applications, generic Xt (e.g. Athena)
+ applications, and raw Xlib applications. An XEmacs variant which
+ supports GTK+ is available (integration as an option in the XEmacs
+ mainline is planned for XEmacs 22), although code to take
+ advantage of the support is as yet scarce.
+
+ An XEmacs frame can be placed within an "external client widget"
+ managed by another application. This allows an application to use
+ an XEmacs frame as its text pane rather than the standard Text
+ widget that is provided with Motif or Athena.
+
+*Community Participation*
+ Joining the XEmacs development team is simple. Mail to XEmacs
+ Developers <xemacs-beta@xemacs.org>, and you're in! (If you want
+ to be, of course. You're also welcome to just post
+ development-related questions and bug reports.) The GNU Emacs
+ development team and internal mailing lists are still by invitation
+ only.
+
+ The "bleeding edge" of mainline XEmacs development is available by
+ anonymous CVS as are some subsidiary branches (check out the
+ xemacs-gtk module for the latest in GUI features!)
+
+ Development and maintenance of Lisp libraries is separated from
+ the core editor development at a fairly low level. This provides
+ better modularization and a better division of responsibility
+ between external library maintainers and the XEmacs core
+ development team. Even for packages the size of Gnus, XEmacs users
+ normally have access to a pre-built version within a few weeks of
+ a major release, and minor updates often within days.
+
+ CVS commit authority is broadly dispersed. Recognized maintainers
+ of LISP libraries who are willing to maintain XEmacs packaged
+ versions automatically qualify for CVS accounts for their packages.

+
+Q1.6.3: How much does XEmacs differ?
+------------------------------------
+
+RMS has asserted at times that XEmacs is merely a "patch" on top of GNU
+Emacs (*note Q1.6.4::). In fact, probably not more than 5% of the
+code, if that, remains unchanged, and nearly 14 years of work has gone
+into XEmacs at this point. (GNU Emacs itself is only than 20 years old,
+and thus XEmacs has existed as a separate product for over 2/3 of the
+lifespan of GNU Emacs.) As a point of comparison, XEmacs 21.5 has
+perhaps 65,000 more lines of C code than GNU Emacs 21.2.
+
+ However, the XEmacs developers strive to keep their code compatible
+with GNU Emacs, especially on the Lisp level. Much effort goes into
+"synching" the XEmacs Elisp code with recent GNU Emacs releases so as to
+benefit from GNU Emacs development work. (In contrast, almost no code
+from XEmacs has made it into GNU Emacs, and in fact the GNU Emacs
+developers are instructed by RMS not to even look at XEmacs source code!
+This stems from self-imposed licensing restrictions on the part of GNU
+Emacs - and almost certainly out of hostility, as well.)
+
+\1f
+File: xemacs-faq.info, Node: Q1.6.4, Next: Q1.6.5, Prev: Q1.6.3, Up: Introduction
+
+Q1.6.4: Is XEmacs "GNU"?
+------------------------
+
+RMS insists on the term "GNU XEmacs" and maintains that
+
+ XEmacs is GNU software because it's a modified version of a GNU
+ program. And it is GNU software because the FSF is the copyright
+ holder for most of it, and therefore the legal responsibility for
+ protecting its free status falls on us whether we want it or not.
+ This is why the term "GNU XEmacs" is legitimate.
+
+ In fact, FSF is _not_ the copyright holder for most of the code, as
+very little unmodified FSF code remains (*note Q1.6.3::).
+
+ Furthermore, RMS's assertion that XEmacs is "GNU" seems rather
+bizarre to the XEmacs developers given RMS's hostility and general lack
+of interest in cooperation. "GNU" software in general is part of the
+GNU Project, is distributed by it on their FTP site, and receives
+support (or at least cooperation), as well as implicit endorsement,
+from it. The GNU Project, however, has never supported XEmacs and never
+distributed XEmacs, and RMS's hostility is the farthest thing possible
+from an endorsement. In fact, the GNU Project distributes a number of
+non-GNU software projects on the FSF web site, but again XEmacs is not
+one of them.
+

+
+Q1.6.5: What is the correct way to refer to XEmacs and GNU Emacs?
+-----------------------------------------------------------------
+
+Unfortunately even the naming of these two applications has become
+politicized. Much of this stems from RMS, who has a history of
+politicizing similar issues. (Compare the controversy over "Lignux" and
+"GNU/Linux".) We would prefer that the terms "XEmacs" and "GNU Emacs"
+be used, which are neutral and acceptable to most people. RMS,
+however, is not willing to accept these terms. He insists that, if his
+product is called "GNU Emacs", then ours must be called "GNU XEmacs".
+(For our opinion of this term, *Note Q1.6.4::.) On the other hand, if
+our product is to be called "XEmacs", as we prefer, then his product
+must simply be called "Emacs". The intent of this seems clear: RMS
+wants to make sure the names reflect his view that his version is the
+"real" Emacs and ours is merely a derivative, second-class product
+(*note Q1.6.3::).
+
+ The XEmacs developers hope that you will use the neutral terms
+"XEmacs" and "GNU Emacs" for these two specific products. "Emacs", on
+the other hand, is a generic term for a class of programmable text
+editors with a similar look-and-feel, and usually a Lisp-based
+extension language. These trace themselves back to early editors such
+as EINE, ZWEI, ZMACS and Multics Emacs. *Note A History of Emacs:
+(internals)A History of Emacs.
+
+ We also call upon RMS, in the spirit of furthering cooperation, to
+stop politicizing this issue and use the neutral terms "XEmacs" and
+"GNU Emacs". We have already acceded to RMS' wishes in this respect,
+and we expect him to do the same. (In the past, the XEmacs developers
+often used the terms "FSF Emacs" or "FSFmacs" or "RMSmacs" in reference
+to GNU Emacs; these terms were apparently modeled after RMS' own usage
+of "Gosmacs" and "Gosling Emacs" in reference to Unipress Emacs,
+produced by James Gosling. RMS, however, considers such terms to be
+insulting, so we refrain from using them as much as possible in
+preference to GNU Emacs.)

+
+Q1.6.6: Why haven't XEmacs and GNU Emacs merged?
+------------------------------------------------
+
+There are currently irreconcilable differences in the views about
+technical, programming, design, organizational and legal matters
+between Richard Stallman (RMS), the author and leader of the GNU Emacs
+project, and the XEmacs development team which provide little hope for
+a merge to take place in the short-term future. There have been
+repeated attempts at merging by all of the major XEmacs developers,
+starting from the early days of Lucid Emacs (in 1991), but they have
+all failed. RMS has very strong views about how GNU Emacs should be
+structured and how his project should be run, and during the repeated
+merge efforts has never demonstrated any realistic interest in
+sufficiently compromising or ceding control to allow a middle ground to
+be found. The basic problem seems to be the very different goals of
+RMS and the XEmacs project. The primary goals of the XEmacs project
+are technical and organizational - we want to create the best editor
+possible, and to make it as easy as possible for people around the
+world to contribute. The primary goals of RMS, on the other hand, are
+political, and GNU Emacs, and any potential merge efforts with XEmacs,
+are strictly subservient to these goals. In fact, in many ways RMS
+sees GNU Emacs as the "poster child" of his aims, the one program in
+the GNU project that above all others must set an example to the world.
+(This has to do with the fact that GNU Emacs was the first program in
+the GNU project, and the only one that he is still personally involved
+with on a day-to-day basis.) Given his goals, his position is
+completely reasonable - but unfortunately, makes any merge impossible.
+
+ From the XEmacs perspective, the most intractable issues appear to be
+legal and organizational, specifically:
+
+ * RMS requires "legal papers" to be signed for all contributions of
+ code to GNU Emacs over 10 lines or so, transferring the copyright
+ and all legal rights to the code to the Free Software Foundation.
+ XEmacs does not and has never required this, since it has the
+ practical effect of discouraging individual and in particular
+ corporate contributions - corporations will almost never sign away
+ their legal rights to code since it makes it impossible to reuse
+ the code in any product that whose license is not compatible with
+ the GNU General Public License. Since RMS has shown no
+ inclination to compromise on this issue, a merge would require
+ that most of the existing XEmacs code would need to be thrown away
+ and rewritten - something the XEmacs developers are understandably
+ reluctant to do.
+
+ * A repeated stumbling block in the merge talks has been the issue of
+ organizational control over the resulting product. RMS has made it
+ clear that he intends to have final say over design issues in a
+ merged Emacs. Unfortunately, RMS and the XEmacs developers have
+ repeatedly clashed over design decisions, and RMS' insistence on
+ getting his way in such disagreements was the very reason for the
+ split in the first place. This same issue has come up again and
+ again in merge talks and we have never been able to come to a
+ satisfactory resolution. To the extent that RMS is willing to
+ compromise at all, it appears to be of a purely political rather
+ than technical nature - "If we support this feature of yours, we
+ also get to support this other feature of mine." The XEmacs
+ developers cannot see how such a process would lead to anything
+ but a mess of incompatible things hodgepodged together.
+
+ * Because of the years of separate development, distinct and
+ incompatible interfaces have developed and merging would be
+ extremely difficult even with the above non-technical issues
+ resolved. The problem has been exacerbated by the issue of legal
+ papers - because XEmacs code is not "kosher" from RMS'
+ perspective, he discourages developers from even looking at it out
+ of legal concerns. Although it is still possible to read the
+ XEmacs documentation and run the program, the practical effect of
+ this prohibition has been to strongly discourage code-sharing and
+ cooperative development - although a great deal of GNU Emacs code
+ has been incorporated into XEmacs, practically none has gone the
+ other direction.
+
+ If you have a comment to add regarding the merge, it is a good idea
+to avoid posting to the newsgroups, because of the very heated flamewars
+that often result. Mail your questions to <xemacs-beta@xemacs.org> and
+<emacs-devel@gnu.org>.

+
+In order to reduce the size and increase the maintainability of XEmacs,
+the majority of the Elisp packages that came with previous releases
+have been unbundled. They have been replaced by the package system.
+Each elisp add-on (or groups of them when they are small) now comes in
+its own tarball that contains a small search hierarchy.
+
+ You select just the ones you need. Install them by untarring them
+into the right place. On startup XEmacs will find them, set up the load

+Both the stable and development versions of XEmacs include
+internationalization support (aka MULE). MULE currently (21.4) works on
+UNIX and Linux systems. It is possible to build with MULE on Windows
+systems, but if you really need MULE on Windows, it is recommended that
+you build and use the development (21.5) version, and deal with the
+instability of the development tree. Binaries compiled without MULE
+support run faster than MULE capable XEmacsen.

+
+If you would like to help, you may want to join the

+who speak/write languages other than English, who are willing to use

+Q1.8.4: Can XEmacs messages come out in a different language?
+-------------------------------------------------------------
+
+The message-catalog support was written but is badly bit-rotted. XEmacs

+not either.
+
+ However, menubar localization _does_ work. To enable it, add to

+
+ Emacs*XlwMenu.resourceLabels: True
+ Emacs*XlwMenu.file.labelString: Fichier

+(including all of the ISO 8859 family, the Indic languages, Thai, and
+so on), and SKK, for Japanese. (SKK also supports an interface to an
+external "dictionary server" process.) Quail supports both typical
+"dead-key" methods (eg, in the "latin-1-prefix" method, `" a' produces
+ä, LATIN SMALL LETTER A WITH DIAERESIS), and the complex
+dictionary-based phonetic methods used for Asian ideographic languages
+like Chinese.
+
+ Lisp implementations can be less powerful (but they are not
+perceptibly inefficient), and of course are not portable to non-Emacs
+applications. The incompatibility can be very annoying. On the other
+hand, they require no special platform support or external libraries,
+so if you can display the characters, Mule can input them for you and
+you can edit, anywhere.
+
+ _Generic platform support_ is currently limited to the X Input
+Method (XIM) framework, although support for MSIME (for MS Windows) is
+planned, and IIIMF (Sun's Internet-Intranet Input Method Framework)
+support is extremely desirable. XIM is enabled at build time by use of
+the `--with-xim' flag to `configure'. For use of XIM, see your
+platform documentation. However, normally the input method you use is
+specified via the `LANG' and `XMODIFIERS' environment variables.
+
+ Of course, input skills are portable across most applications.
+However, especially in modern GUI systems the habit of using bucky bits
+has fallen into sad disuse, and many XIM systems are poorly configured
+for use with Emacs. For example, the kinput2 input manager (a separate
+process providing an interface between Japanese dictionary servers such
+as Canna and Wnn, and the application) tends to gobble up keystrokes
+generating Meta characters. This means that to edit while using an XIM
+input method, you must toggle the input method off every time you want
+to use `M-f'. Your mileage may vary.
+
+ _Library interfaces_ are most common for Japanese, although Wnn
+supports Chinese (traditional and simplified) and Korean. There are
+Chinese and Korean input servers available, but we do not know of any
+patches for XEmacs to use them directly. You can use them via
+IM-enabled terminals, by manipulating the terminal coding systems. We
+describe only the Japanese-oriented systems here. The advantage of
+these systems is that they are very powerful, and on platforms where
+they are available there is typically a wide range of applications that
+support them. Thus your input skills are portable across applications.
+
+ Mule provides built-in interfaces to the following input methods:
+Wnn4, Wnn6, Canna, and SJ3. These can be configured at build time.
+There are patches available (no URL, sorry) to support the SKK server,
+as well. Wnn and SJ3 use the `egg' user interface. The interface for
+Canna is specialized to Canna.
+
+ Wnn supports Japanese, Chinese and Korean. It is made by OMRON and
+Kyôto University. It is a powerful and complex system. Wnn4 is free
+and Wnn6 is not. Wnn uses grammatical hints and probability of word
+association, so in principle Wnn can be cleverer than other methods.
+
+ Canna, made by NEC, supports only Japanese. It is a simple and
+powerful system. Canna uses only grammar, but its grammar and
+dictionary are quite sophisticated. So for standard modern Japanese,
+Canna seems cleverer than Wnn4. In addition, the UNIX version of Canna
+is free (now there is a Microsoft Windows version).
+
+ SJ3, by Sony, supports only Japanese.
+
+ Egg consists of following parts:
+
+ 1. Input character Translation System (ITS) layer. It translates
+ ASCII inputs to Kana/PinYin/Hangul characters.
+
+ 2. Kana/PinYin/Hangul to Kanji transfer layer. The interface layer
+ to network Kana-Kanji server (Wnn and Sj3).
+
+ These input methods are modal. They have a raw (alphabet) mode, a
+phonetic input mode, and Kana-Kanji transfer mode. However there are
+mode-less input methods for Egg and Canna. `boiled-egg' is a mode-less
+input method running on Egg. For Canna, `canna.el' has a tiny
+boiled-egg-like command, `(canna-boil)', and there are some
+boiled-egg-like utilities.

+Q1.8.6: How do I portably code for MULE/XEmacs?
+-----------------------------------------------
+
+MULE has evolved rapidly over the last few years, and the original third
+party patch (for GNU Emacs 19), GNU Emacs 20+, and XEmacs 20+ have quite
+different implementations. The APIs also vary although recent versions
+of XEmacs have tended to converge to the GNU Emacs standard.
+
+ MULE implementations are going to continue to evolve. Both GNU Emacs
+and XEmacs are working hard on Unicode support, which will involve new
+APIs and probably variations on old ones. For XEmacs 22, the old ISO
+2022-based system for recognizing encodings will be replaced by a much
+more flexible system, which should improve accuracy of automatic coding
+detections, but will also involve new APIs.
+
+ MORIOKA Tomohiko <morioka@jaist.ac.jp> writes:
+
+ The application implementor must write separate code for these mule
+ variants. [Please don't hesitate to report these variants to us;
+ they are not, strictly speaking, bugs, but they give third-party
+ developers the same kind of creepy-crawly feeling. We'll do what
+ we can. - Ed.]
+
+ MULE and the next version of Emacs are similar but the symbols are
+ very different--requiring separate code as well.
+
+ Namely we must support 3 kinds of mule variants and 4 or 5 or 6
+ kinds of emacs variants... (;_;) I'm shocked, so I wrote a wrapper
+ package called `emu' to provide a common interface. [There is an
+ XEmacs package of APEL which provides much more comprehensive
+ coverage. Be careful, however; APEL has problems of its own. -
+ Ed.]
+
+ I have the following suggestions about dealing with mule variants:
+
+ * `(featurep 'mule)' `t' on all mule variants
+
+ * `(boundp 'MULE)' is `t' on only MULE. Maybe the next version
+ of Emacs will not have this symbol.
+
+ * MULE has a variable `mule-version'. Perhaps the next version
+ of Emacs will have this variable as well.
+
+ Following is a sample to distinguish mule variants:
+
+ (if (featurep 'mule)
+ (cond ((boundp 'MULE)
+ ;; for original Mule
+ )
+ ((string-match "XEmacs" emacs-version)
+ ;; for XEmacs with Mule

+
+Q1.8.8: Does XEmacs support Unicode?
+------------------------------------
+
+To get Unicode support, you need a Mule-enabled XEmacs.
+
+ 21.5 has internal support for Unicode and supports it fully,
+although we don't yet use it as the internal encoding.
+
+ 21.4 supports Unicode partially - as an external encoding for files,
+processes, and terminals, but without font support. *Note How does
+XEmacs display Unicode?: Q1.8.9. To get Unicode support in 21.4,
+install Mule-UCS from packages in the usual way, and put
+
+ (require 'un-define)
+ (set-coding-priority-list '(utf-8))
+ (set-coding-category-system 'utf-8 'utf-8)
+
+ in your init file to enable the UTF-8 coding system. You may wish to
+view the documentation of `set-coding-priority-list' if you find that
+files that are not UTF-8 are being mis-recognized as UTF-8.
+
+ Install standard national fonts (not Unicode fonts) for all character
+sets you use. *Note How does XEmacs display Unicode??: Q1.8.9.
+
+ Mule-UCS also supports 16-bit forms of Unicode (UTF-16). It does not
+support 31-bit forms of Unicode (UTF-32 or UCS-4).
+
+\1f
+File: xemacs-faq.info, Node: Q1.8.9, Prev: Q1.8.8, Up: Introduction
+
+Q1.8.9: How does XEmacs display Unicode?
+----------------------------------------
+
+Mule doesn't have a Unicode charset internally, so there's nothing to
+bind a Unicode registry to. It would not be straightforward to create,
+either, because Unicode is not ISO 2022-compatible. You'd have to
+translate it to multiple 96x96 pages.
+
+ This means that Mule-UCS uses ordinary national fonts for display.
+This is not really a problem, except for those languages that use the
+Unified Han characters. The problem here is that Mule-UCS maps from
+Unicode code points to national character sets in a deterministic way.
+By default, this means that Japanese fonts are tried first, then
+Chinese, then Korean. To change the priority ordering, use the command
+`un-define-change-charset-order'.
+
+ It also means you can't use Unicode fonts directly, at least not
+without extreme hackery. You can run -nw with
+(set-terminal-coding-system 'utf-8) if you really want a Unicode font
+for some reason.
+
+ Real Unicode support will be introduced in XEmacs 22.0.

+------------------------------------------
+
+See the file `etc/NEWS' for information on new features and other
+user-visible changes since the last version of XEmacs.
+
+ The file `INSTALL' in the top-level directory says how to bring up
+XEmacs on Unix and Cygwin, once you have loaded the entire subtree of
+this directory.
+
+ See the file `nt/README' for instructions on building XEmacs for

+Q2.0.2: Where do I find external libraries?
+-------------------------------------------
+
+All external libraries used by XEmacs can be found on the XEmacs web
+site `http://www.xemacs.org/Download/optLibs.html'.
+
+ The library versions available here are known to work with XEmacs.
+(Newer versions will probably work as well but we can't guarantee it.)
+We try to keep the libraries up-to-date but may not always succeed.
+Check the above page for the canonical locations of the external
+libraries, allowing you to download the latest, bleeding-edge versions.

+
+Q2.0.3: How do I specify the paths that XEmacs uses for finding files?
+----------------------------------------------------------------------
+
+You can specify what paths to use by using a number of different flags
+when running configure. See the section MAKE VARIABLES in the top-level
+file INSTALL in the XEmacs distribution for a listing of those flags.
+
+ Most of the time, however, the simplest fix is: *do not* specify
+paths as you might for GNU Emacs. XEmacs can generally determine the
+necessary paths dynamically at run time. The only path that generally
+needs to be specified is the root directory to install into. That can
+be specified by passing the `--prefix' flag to configure. For a
+description of the XEmacs install tree, please consult the `NEWS' file.

+
+Q2.0.4: Running XEmacs without installing
+-----------------------------------------
+
+How can I just try XEmacs without installing it?
+
+ XEmacs will run in place without requiring installation and copying
+of the Lisp directories, and without having to specify a special
+build-time flag. It's the copying of the Lisp directories that
+requires so much space. XEmacs is largely written in Lisp.
+
+ A good method is to make a shell alias for xemacs:
+
+ alias xemacs=/src/xemacs-21.5/src/xemacs
+
+ (You will obviously use whatever directory you downloaded the source
+tree to instead of `/src/xemacs-21.5').
+
+ This will let you run XEmacs without massive copying.
+
+\1f
+File: xemacs-faq.info, Node: Q2.0.5, Next: Q2.1.1, Prev: Q2.0.4, Up: Installation
+
+Q2.0.5: XEmacs is too big
+-------------------------
+
+The space required by the installation directories can be reduced
+dramatically if desired. Gzip all the .el files. Remove all the
+packages you'll never want to use. Remove the TexInfo manuals. Remove
+the Info (and use just hardcopy versions of the manual). Remove most
+of the stuff in etc. Remove or gzip all the source code. Gzip or
+remove the C source code. Configure it so that copies are not made of
+the support lisp.
+
+ These are all Emacs Lisp source code and bytecompiled object code.
+You may safely gzip everything named *.el here. You may remove any
+package you don't use. _Nothing bad will happen if you delete a package
+that you do not use_. You must be sure you do not use it though, so be
+conservative at first.
+
+ Any package with the possible exceptions of xemacs-base, and EFS are
+candidates for removal. Ask yourself, _Do I ever want to use this
+package?_ If the answer is no, then it is a candidate for removal.
+
+ First, gzip all the .el files. Then go about package by package and
+start gzipping the .elc files. Then run XEmacs and do whatever it is
+you normally do. If nothing bad happens, then remove the package. You
+can remove a package via the PUI interface (`M-x pui-list-packages',
+then press `d' to mark the packages you wish to delete, and then `x' to
+delete them.
+
+ Another method is to do `M-x package-get-delete-package'.
+
+2.1: Package Installation
+=========================
+
+\1f
+File: xemacs-faq.info, Node: Q2.1.1, Next: Q2.1.2, Prev: Q2.0.5, Up: Installation
+
+Q2.1.1: How do I install the packages?
+--------------------------------------
+
+There are three ways to install the packages.
+
+ 1. Manually, all at once, using the 'Sumo Tarball'.
+
+ 2. Manually, using individual package tarballs.
+
+ 3. Automatically, using the package tools from XEmacs.
+
+ If you don't want to mess with the packages, it is easiest to just
+grab them manually, all at once. (For the other two ways, *Note
+Q2.1.2::, and *Note Q2.1.3::.) Download the file
+
+ `xemacs-sumo.tar.gz'
+
+ For an XEmacs compiled with Mule you also need
+
+ `xemacs-mule-sumo.tar.gz'
+
+ These are in the `packages' directory on your XEmacs mirror archive:
+`ftp://ftp.xemacs.org/pub/xemacs/packages' or its mirrors. N.B. They
+are called 'Sumo Tarballs' for good reason. They are currently about
+19MB and 4.5MB (gzipped) respectively.
+
+ Install them on Unix and Mac OS X using the shell/Terminal command
+
+ `cd $prefix/lib/xemacs ; gunzip -c <tarballname> | tar xf -'
+
+ Where `$prefix' is what you gave to the `--prefix' flag to
+`configure', and defaults to `/usr/local'.
+
+ If you have GNU tar you can use:
+
+ `cd $prefix/lib/xemacs ; tar zxvf <tarballname>'
+
+ If you have the packages somewhere nonstandard and don't want to
+bother with `$prefix' (for example, you're a developer and are compiling
+the packages yourself, and want your own private copy of everything),
+you can also directly specify this using `configure'. To do this with
+21.5 and above use the `--with-package-prefix' parameter to specify the
+directory under which you untarred the above tarballs. Under 21.4 and
+previous you need to use `--package-path'. Using these options looks
+something like this:
+
+ configure --package-path="~/.xemacs::/src/xemacs/site-packages:/src/xemacs/xemacs-packages:/src/xemacs/mule-packages" ...
+
+ Under Windows, you need to place the above `tar.gz' files in the
+directory specified using the `PACKAGE_PREFIX' value in `nt/config.inc'
+and by default is `\Program Files\XEmacs'. (To untar a `tar.gz' file
+you will need to use a utility such as WinZip, unless you have Cygwin
+or a similar environment installed, in which case the above Unix shell
+command should work fine.) If you want the packages somewhere else,
+just change `PACKAGE_PREFIX'.
+
+ Note that XEmacs finds the packages automatically anywhere underneath
+the directory tree where it expects to find the packages. All you need
+to do is put stuff there; you don't need to run any program to tell
+XEmacs to find the packges, or do anything of that sort.
+
+ However, XEmacs will only notice newly installed packages when it
+starts up, so you will have to restart if you are already running
+XEmacs.
+
+ For more details, *Note Startup Paths: (xemacs)Startup Paths, and
+*Note Packages: (xemacs)Packages.
+
+ As the Sumo tarballs are not regenerated as often as the individual
+packages, it is recommended that you use the automatic package tools
+afterwards to pick up any recent updates.
+
+ _NOTE_: For detailed information about how the package hierarchies
+work, *Note Package Overview: (lispref)Package Overview.

+
+Q2.1.2: Can I install the packages individually?
+------------------------------------------------
+
+Yes, you can download individual packages from the FTP site (*note
+Q2.1.1::). Since packages are automatically noticed at startup, you
+just have to put them in the right place.
+
+ Note: If you are upgrading packages already installed, it's best to
+remove the old package first (*note Q2.1.4::).
+
+ For example if we are installing the `xemacs-base' package (version
+1.48):
+
+ mkdir $prefix/lib/xemacs/xemacs-packages RET # if it does not exist yet
+ cd $prefix/lib/xemacs/xemacs-packages RET
+ gunzip -c /path/to/xemacs-base-1.48-pkg.tar.gz | tar xvf - RET
+
+ Or if you have GNU tar, the last step can be:
+
+ tar zxvf /path/to/xemacs-base-1.48-pkg.tar.gz RET
+
+ For MULE related packages, it is best to untar into the
+`mule-packages' hierarchy, i.e. for the `mule-base' package, version
+1.37:
+
+ mkdir $prefix/lib/xemacs/mule-packages RET # if it does not exist yet
+ cd $prefix/lib/xemacs/mule-packages RET
+ gunzip -c /path/to/mule-base-1.37-pkg.tar.gz | tar xvf - RET
+
+ Or if you have GNU tar, the last step can be:
+
+ tar zxvf /path/to/mule-base-1.37-pkg.tar.gz RET

+
+Q2.1.3: Can I install the packages automatically?
+-------------------------------------------------
+
+XEmacs comes with some tools to make the periodic updating and
+installing easier. It will notice if new packages or versions are
+available and will fetch them from the FTP site.
+
+ Unfortunately this requires that a few packages are already in place.
+You will have to install them by hand as above or use a SUMO tarball.
+This requirement will hopefully go away in the future. The packages you
+need are:
+
+ efs - To fetch the files from the FTP site or mirrors.
+ xemacs-base - Needed by efs.
+
+ and optionally:
+
+ mailcrypt - For PGP verification of the package-index file.
+
+ After installing these by hand, fire up XEmacs and follow these
+steps.
+
+ 1. Choose a download site.
+ * via menu: Tools -> Packages -> Set Download Site
+
+ * via keyb: M-x customize-variable RET package-get-remote RET
+ (put in the details of remote host and directory)
+
+ If the package tarballs _AND_ the package-index file are in a
+ local directory, you can: M-x pui-set-local-package-get-directory
+ RET
+
+ 2. Obtain a list of packages and display the list in a buffer named
+ "*Packages*".
+ * menu: Tools -> Packages -> List & Install
+
+ * keyb: M-x pui-list-packages RET
+
+ XEmacs will now connect to the remote site and download the latest
+ package-index file.
+
+ The resulting buffer, "*Packages*" has brief instructions at the
+ end of the buffer.
+
+ 3. Choose the packages you wish to install.
+ * mouse: Click button 2 on the package name.
+
+ * keyb: RET on the package name
+
+ 4. Make sure you have everything you need.
+ * menu: Packages -> Add Required
+
+ * keyb: r
+
+ XEmacs will now search for packages that are required by the ones
+ that you have chosen to install and offer to select those packages
+ also.
+
+ For novices and gurus alike, this step can save your bacon. It's
+ easy to forget to install a critical package.
+
+ 5. Download and install the packages.
+ * menu: Packages -> Install/Remove Selected
+
+ * keyb: x

+
+Q2.1.4: Can I upgrade or remove packages?
+-----------------------------------------
+
+As the exact files and their locations contained in a package may
+change it is recommended to remove a package first before installing a
+new version. In order to facilitate removal each package contains an
+pgkinfo/MANIFEST.pkgname file which list all the files belong to the
+package. M-x package-admin-delete-binary-package RET can be used to
+remove a package using this file.

+Unless you are an advanced user, just install everything.

+
+Q2.1.6: Can you describe the package location process in more detail?
+---------------------------------------------------------------------
+
+On startup XEmacs looks for packages in so-called package hierarchies.
+Normally, there are three system wide hierarchies, like this:
+
+ $prefix/lib/xemacs/xemacs-packages/
+ Normal packages go here.
+
+ $prefix/lib/xemacs/mule-packages/
+ Mule packages go here and are only searched by MULE-enabled XEmacsen.
+
+ $prefix/lib/xemacs/site-packages/
+ Local and 3rd party packages go here.
+
+ This is what you get when you untar the SUMO tarballs under
+`$prefix/lib/xemacs'.
+
+ `$prefix' is specified using the `--prefix' parameter to
+`configure', and defaults to `usr/local'.
+
+ If the package path is not explicitly specified, XEmacs looks for the
+package directory `xemacs-packages' (and `mule-packages' and
+`site-packages') first under `~/.xemacs', then for a sister directory
+`lib/xemacs-VERSION' of the directory in which the XEmacs executable is
+located, then for a sister directory `lib/xemacs'. The XEmacs
+executable (under Unix at least) is installed by default in
+`/usr/local/bin'; this explains why XEmacs in its default installation
+will find packages that you put under `/usr/local/lib/xemacs'.
+
+ You can specify where exactly XEmacs looks for packages by using the
+`--with-package-prefix' or `--with-package-path' parameters to
+`configure' (or the equivalent settings in `config.inc', under
+Windows), or setting the `EMACSPACKAGEPATH' environment variable (which
+has the same format as `--with-package-path'). *Note Q2.1.1::.
+
+ See `configure.usage' for more info about the format of these
+`configure' parameters.
+
+ In addition to the system wide packages, each user can have his own
+packages installed under `~/.xemacs/'. If you want to install packages
+there using the interactive tools, you need to set
+`package-get-install-to-user-init-directory' to `t'.
+
+ The site-packages hierarchy replaces the old `site-lisp' directory.
+XEmacs no longer looks into a `site-lisp' directly by default. A good
+place to put `site-start.el' would be in
+`$prefix/lib/xemacs/site-packages/lisp/'.

+
+ Because of the way XEmacs (and every other Emacsen, AFAIK) is

+

+
+Q2.3.1: What exactly are all the different ways to build XEmacs under Windows?
+------------------------------------------------------------------------------
+
+XEmacs can be built in several ways in the MS Windows environment.
+
+ The standard way is what we call the "native" port. It uses the
+Win32 API and has no connection with X whatsoever - it does not require
+X libraries to build, nor does it require an X server to run. The
+native port is the most reliable version and provides the best graphical
+support. Almost all development is geared towards this version, and
+there is little reason not to use it.
+
+ The second way to build is the Cygwin port. It takes advantage of
+Cygnus emulation library under Win32. *Note What are Cygwin and MinGW:
+Q1.2.5, for more information.
+
+ A third way is the MinGW port. It uses the Cygwin environment to
+build but does not require it at runtime. *Note What are Cygwin and
+MinGW: Q1.2.5, for more information.
+
+ Finally, you might also be able to build the non-Cygwin, non-MinGW
+"X" port. This was actually the first version of XEmacs that ran under
+MS Windows, and although the code is still in XEmacs, it's essentially
+orphaned and it's unlikely it will compile without a lot of work. If
+you want an MS Windows versin of XEmacs that supports X, use the Cygwin
+version. (The X support there is actively maintained, so that Windows
+developers can test the X support in XEmacs.)

+some beta testers currently trying to compile with VC.NET, aka version
+7.0, but we can't yet report complete success.) For the Cygwin and
+MinGW versions, you need the Cygwin environment, which comes with GCC,

+best.) You should go ahead and install everything - you'll get various
+ancillary libraries that XEmacs needs or likes, e.g. XPM, PNG, JPEG,
+TIFF, etc. You can also get X Windows here, if you want to compile
+under X.
+
+ If you want to compile without X, you will need the `xpm-nox'
+library, which must be specifically selected in the Cygwin netinstaller;
+it is not selected by default. The package has had various names.
+Currently it is called `cygXpm-noX4.dll'.

+--------------------------------------
+
+Similar as on Unix; use the usual `configure' and `make' process. Some
+problems to watch out for:
+
+ * make sure HOME is set. This controls where you `init.el' file
+ comes from;
+
+ * `CYGWIN' needs to be set to `tty' for process support to work;
+
+ * picking up some other grep or other UNIX-like tools can kill
+ configure;
+
+ * static heap too small, adjust `src/sheap-adjust.h' to a more
+ positive number;
+
+ * (Unconfirmed) The Cygwin version doesn't understand
+ `//machine/path' type paths so you will need to manually mount a
+ directory of this form under a unix style directory for a build to
+ work on the directory;
+
+ * If you're building *WITHOUT* X11, don't forget to change symlinks
+ `/usr/lib/libXpm.a' and `/usr/lib/libXpm.dll.a' to point to the
+ non-X versions of these libraries. By default they point to the X
+ versions. So:
+
+ /usr/lib/libXpm.a -> /usr/lib/libXpm-noX.a
+ /usr/lib/libXpm.dll.a -> /usr/lib/libXpm-noX.dll.a
+

+
+ * Specify the target location of the extra libs on the command line

+----------------------------------------
+
+To compile under Cygwin, all you need to do is install XFree86, which

+`http://www.cygwin.com/'. Once installed, `configure' should

+
+ As noted above, the non-Cygwin X support is basically orphaned, and
+probably won't work. But if it want to try, it's described in
+`nt/README' in some detail. Basically, you need to get X11 libraries
+from `http://ftp.x.org', and compile them. If the precompiled versions

+
+Q2.4.1: How do I deal with bugs or with problems building, installing, or running?
+----------------------------------------------------------------------------------
+
+The file `PROBLEMS' contains information on many common problems that
+occur in building, installing and running XEmacs.
+
+ Reports of bugs in XEmacs should be sent to
+<xemacs-beta@xemacs.org>. You can also post to the newsgroup

+<xemacs@xemacs.org>), but it is less likely that the developers will
+see it in a timely fashion. *Note Bugs: (xemacs)Bugs, for more
+information on how to report bugs. *Note Q1.4.2::, for more
+information on mailing lists relating to XEmacs.
+
+ There are three ways to read the Bugs section.

+ 2. With Info. First, start XEmacs. From the menu, select

+ i' to enter Info, then `m XEmacs RET' to get to the Emacs manual,
+ then `m Bugs RET' to get to the section on bugs. Or use
+ standalone Info in a like manner. (Standalone Info is part of the

+
+Q2.4.2: Help! XEmacs just crashed on me!
+-----------------------------------------
+
+First of all, don't panic. Whenever XEmacs crashes, it tries extremely
+hard to auto-save all of your files before dying. (The main time that
+this will not happen is if the machine physically lost power or if you
+killed the XEmacs process using `kill -9'). The next time you try to
+edit those files, you will be informed that a more recent auto-save
+file exists. You can use `M-x recover-file' to retrieve the auto-saved
+version of the file.
+
+ You can use the command `M-x recover-session' after a crash to pick
+up where you left off.
+
+ Now, XEmacs is not perfect, and there may occasionally be times, or
+particular sequences of actions, that cause it to crash. If you can
+come up with a reproducible way of doing this (or even if you have a
+pretty good memory of exactly what you were doing at the time), the
+maintainers would be very interested in knowing about it. The best way
+to report a bug is using `M-x report-emacs-bug' (or by selecting `Send
+Bug Report...' from the Help menu). If that won't work (e.g. you can't
+get XEmacs working at all), send ordinary mail to
+<xemacs-beta@xemacs.org>. _MAKE SURE_ to include the output from the
+crash, especially including the Lisp backtrace, as well as the XEmacs
+configuration from `M-x describe-installation' (or equivalently, the
+file `Installation' in the top of the build tree). Note that the
+developers do _not_ usually follow `comp.emacs.xemacs' on a regular
+basis; thus, this is better for general questions about XEmacs than bug
+reports.
+
+ If at all possible, include a C stack backtrace of the core dump that
+was produced. This shows where exactly things went wrong, and makes it
+much easier to diagnose problems. To do this under Unix and Mac OS X,
+you need to locate the core file (it's called `core', and is usually
+sitting in the directory that you started XEmacs from, or your home
+directory if that other directory was not writable). Then, go to that
+directory and execute a command like:
+
+ gdb `which xemacs` core
+
+ and then issue the command `where' to get the stack backtrace. You
+might have to use `dbx' or some similar debugger in place of `gdb'. If
+you don't have any such debugger available, complain to your system
+administrator.
+
+ It's possible that a core file didn't get produced or the stack trace
+from gdb is garbage, in which case you're out of luck unless you can
+reproduce the bug. A nonexistent core file can happen in some
+circumstances on some operating systems, depending on what exactly
+triggered the crash. It's also possible, however, that your limits are
+set to turn them off. You may be able to reenable them using a command
+like `unlimit coredumpsize' or `ulimit -c'. (To find out how your
+limits are set, use the command `limit'.) However, if you didn't
+explicitly set your limits this way, go complain to your system
+administrator and tell him not to disable core files by default.
+
+ A garbaged stack trace can happen for various reasons. Some versions
+of gdb are broken on certain operating systems and aren't able to read
+the core file. It's also possible that the stack got overwritten
+during the crash. A very simple reason, however, is that your version
+of XEmacs was compiled without debugging information or had the
+debugging information stripped. A compilation with optimization can
+also result in partly or completely garbaged stack trace. In such
+cases, you will need to recompile XEmacs with debugging information and
+without optimization; *Note How to debug an XEmacs problem with a
+debugger: Q2.4.4. Note also that core files currently don't work at
+all under Cygwin, and the only way to get a backtrace is to run XEmacs
+from gdb.
+
+ If you cannot get a backtrace from the core dump, but can reproduce
+the problem, try running XEmacs under gdb. The goal is to get clean C
+and Lisp backtraces and submit a bug report including full
+configuration information as described above, as this will greatly
+assist in the process of tracking down the bug. However, even partial
+information is better than none. The process of getting backtraces
+from gdb is described in detail in *Note How to debug an XEmacs problem
+with a debugger: Q2.4.4.
+
+ If you're under Microsoft Windows, you're out of luck unless you
+happen to have a debugging aid installed on your system, for example
+Visual C++. In this case, the crash will result in a message giving
+you the option to enter a debugger (for example, by pressing `Cancel').
+Do this and locate the stack-trace window. (If your XEmacs was built
+without debugging information, the stack trace may not be very useful.)
+
+ When making a problem report make sure that:
+
+ 1. Report *all* of the information output by XEmacs during the crash.
+
+ 2. You mention what O/S and Hardware you are running XEmacs on.
+
+ 3. What version of XEmacs you are running.
+
+ 4. What build options you are using.
+
+ 5. If the problem is related to graphics and you are running Unix or
+ Mac OS X, we will also need to know what version of the X Window
+ System you are running, and what window manager you are using.
+
+ 6. If the problem happened on a TTY, please include the terminal type.
+
+ 7. Try very hard to get both C and Lisp backtraces, as described
+ above.
+
+ Much of the information above is automatically generated by `M-x
+report-emacs-bug'. Even more, and often useful, information can be
+generated by redirecting the output of `make' and `make check' to a
+file (`beta.err' is the default used by `build-report'), and executing
+`M-x build-report'.

+
+Q2.4.4: How to debug an XEmacs problem with a debugger
+------------------------------------------------------
+
+If XEmacs does crash on you, one of the most productive things you can
+do to help get the bug fixed is to poke around a bit with the debugger.
+Here are some hints:
+
+ * First of all, if the crash is at all reproducible, consider very
+ strongly recompiling your XEmacs with debugging symbols and with no
+ optimization (e.g. with GCC use the compiler flags `-g -O0' -
+ that's an "oh" followed by a zero), and with the configure options
+ `--debug=yes' and `--error-checking=all' (`--enable-debug=yes' and
+ `--enable-error-checking=all' on XEmacs 21.5 or later). This will
+ make your XEmacs run somewhat slower, but you are a lot more
+ likely to catch the problem earlier (closer to its source). It
+ makes it a lot easier to determine what's going on with a
+ debugger. The way to control the compiler flags is with the
+ configuration option `--cflags' (`--with-cflags' in 21.5). If you
+ have a recent version of 21.5, you should use
+ `--without-optimization' in preference to directly setting
+ `--cflags'.
+
+ * If it's not a true crash (_i.e._, XEmacs is hung, or a zombie
+ process), or it's inconvenient to run XEmacs again because XEmacs
+ is already running or is running in batch mode as part of a bunch
+ of scripts, you may be able to attach to the existing process with
+ your debugger. Under Unix and Mac OS X, the typical way to do
+ this is to first use some variant of the `ps' command to figure
+ out the process ID of XEmacs, for example `ps -auxww | grep
+ xemacs' under a BSD variant, `ps -elf | grep xemacs' under Linux
+ or System V, or `ps -aW | grep xemacs' under Cygwin. Then run
+
+ gdb /path/to/xemacs/xemacs ####
+
+ Where `####' is the process id of your XEmacs. (If you're not
+ sure, try using `which xemacs'.) When gdb attaches, the xemacs
+ will stop and you can type `where' in gdb to get a stack trace as
+ usual. To get things moving again, you can just type `quit' in
+ gdb. It'll tell you the program is running and ask if you want to
+ quit anyways. Say `y' and it'll quit and have your emacs continue
+ from where it was at.
+
+ If you're running another debugger, a similar method may work, or
+ you may have to run the debugger first and then use the `attach'
+ command or something similar.
+
+ Under Microsoft Windows, use the menu item `Build->Start
+ Debug->Attach to Process...' and select the XEmacs process from
+ the list given.
+
+ * If you're able to run XEmacs under a debugger and reproduce the
+ crash, here are some things you can do:
+
+ * If XEmacs is hitting an assertion failure, put a breakpoint on
+ `assert_failed()'.
+
+ * If XEmacs is hitting some weird Lisp error that's causing it to
+ crash (e.g. during startup), put a breakpoint on
+ `signal_1()'--this is declared static in `eval.c'.
+
+ * If XEmacs is outputting lots of X errors, put a breakpoint on
+ `x_error_handler()'; that will tell you which call is causing
+ them. Note that the result may not be very useful by default
+ because X Windows normally operates asynchronously: A bunch of
+ commands are buffered up and then sent to the server all at once.
+ This greatly improves performance over a network but means that an
+ error may not be reported until the server receives the commands,
+ which can be long after XEmacs made the erroneous calls. For best
+ results, you need to make the X server synchronous before getting
+ the backtrace. This can be done by starting XEmacs with the
+ `-sync' option or executing the Lisp code `(x-debug-mode t)'.
+
+ * Internally, you will probably see lots of variables that hold
+ objects of type `Lisp_Object'. These are references to Lisp
+ objects. Printing them out with the debugger probably won't be too
+ useful--you'll likely just see a number. To decode them, do this:
+
+ call debug_print (OBJECT)
+
+ where OBJECT is whatever you want to decode (it can be a variable,
+ a function call, etc.). This uses the Lisp printing routines to
+ out a readable representation on the TTY from which the xemacs
+ process was invoked.
+
+ Under 21.5 and later, `dp' is defined as an easier-to-type
+ equivalent of `debug_print'. You can also try `dpa' if you can't
+ see the output from `debug_print' (this will return a string
+ containing the output), or use `debug_p3' if `debug_print' itself
+ triggers a crash (this is a less comprehensive but super-safe way
+ to print out a Lisp object).
+
+ * If you want to get a Lisp backtrace showing the Lisp call stack,
+ do this:
+
+ call debug_backtrace ()
+
+ Under 21.5 and later, `db' is defined as an easier-to-type
+ equivalent of `debug_backtrace'.
+
+ * Using `debug_print' and `debug_backtrace' has two disadvantages -
+ they can only be used with a running (including hung or zombie)
+ xemacs process, and they do not display the internal C structure
+ of a Lisp Object. Even if all you've got is a core dump, all is
+ not lost.
+
+ If you're using GDB, there are some macros in the file
+ `src/.gdbinit' in the XEmacs source distribution that should make
+ it easier for you to decode Lisp objects. This file is
+ automatically read by gdb if gdb is run in the directory where
+ xemacs was built, and contains these useful macros to inspect the
+ state of xemacs:
+
+ `pobj'
+ Usage: pobj lisp_object
+ Print the internal C representation of a lisp object.
+
+ `xtype'
+ Usage: xtype lisp_object
+ Print the Lisp type of a lisp object.
+
+ `lbt'
+ Usage: lbt
+ Print the current Lisp stack trace. Requires a running
+ xemacs process. (It works by calling the db routine
+ described above.)
+
+ `ldp'
+ Usage: ldp lisp_object
+ Print a Lisp Object value using the Lisp printer. Requires a
+ running xemacs process. (It works by calling the dp routine
+ described above.)
+
+ `run-temacs'
+ Usage: run-temacs
+ Run temacs interactively, like xemacs. Use this with
+ debugging tools (like purify) that cannot deal with dumping,
+ or when temacs builds successfully, but xemacs does not.
+
+ `dump-temacs'
+ Usage: dump-temacs
+ Run the dumping part of the build procedure. Use when
+ debugging temacs, not xemacs! Use this when temacs builds
+ successfully, but xemacs does not.
+
+ `check-xemacs'
+ Usage: check-xemacs
+ Run the test suite. Equivalent to 'make check'.
+
+ `check-temacs'
+ Usage: check-temacs
+ Run the test suite on temacs. Equivalent to 'make
+ check-temacs'. Use this with debugging tools (like purify)
+ that cannot deal with dumping, or when temacs builds
+ successfully, but xemacs does not.
+
+ If you are using Sun's `dbx' debugger, there is an equivalent file
+ `src/.dbxrc', which defines the same commands for dbx.
+
+ * If you're using a debugger to get a C stack backtrace and you're
+ seeing stack traces with some of the innermost frames mangled, it
+ may be due to dynamic linking. (This happens especially under
+ Linux.) Consider reconfiguring with `--dynamic=no'
+ (`--with-dynamic=no' in 21.5 or later). Also, sometimes (again
+ under Linux), stack backtraces of core dumps will have the frame
+ where the fatal signal occurred mangled; if you can obtain a stack
+ trace while running the XEmacs process under a debugger, the stack
+ trace should be clean.
+
+ Curtiss <1CMC3466@ibm.mtsac.edu> suggests upgrading to ld.so
+ version 1.8 if dynamic linking and debugging is a problem on Linux.
+
+ * If you're using a debugger to get a C stack backtrace and you're
+ getting a completely mangled and bogus stack trace, it's probably
+ due to one of the following:
+
+ a. Your executable has been stripped. Bad news. Tell your
+ sysadmin not to do this--it doesn't accomplish anything
+ except to save a bit of disk space, and makes debugging much
+ much harder.
+
+ b. Your stack is getting trashed. Debugging this is hard; you
+ have to do a binary-search type of narrowing down where the
+ crash occurs, until you figure out exactly which line is
+ causing the problem. Of course, this only works if the bug
+ is highly reproducible. Also, in many cases if you run
+ XEmacs from the debugger, the debugger can protect the stack
+ somewhat. However, if the stack is being smashed, it is
+ typically the case that there is a wild pointer somewhere in
+ the program, often quite far from where the crash occurs.
+
+ c. If your stack trace has exactly one frame in it, with address
+ 0x0, this could simply mean that XEmacs attempted to execute
+ code at that address, e.g. through jumping to a null function
+ pointer. Unfortunately, under those circumstances, GDB under
+ Linux doesn't know how to get a stack trace. (Yes, this is
+ the fourth Linux-related problem I've mentioned. I have no
+ idea why GDB under Linux is so bogus. Complain to the GDB
+ authors, or to comp.os.linux.development.system.) Again,
+ you'll have to use the narrowing-down process described above.
+
+ d. You will get a Lisp backtrace output when XEmacs crashes, so
+ you'll have something useful.
+
+
+ * If you compile with the newer gcc variants gcc-2.8 or egcs, you
+ will also need gdb 4.17 or above. Earlier releases of gdb can't
+ handle the debug information generated by the newer compilers.
+
+ * In versions of XEmacs before 21.2.27, `src/.gdbinit' was named
+ `src/gdbinit'. This had the disadvantage of not being sourced
+ automatically by gdb, so you had to set that up yourself.
+
+ * If you are running Microsoft Windows, the the file `nt/README' for
+ further information about debugging XEmacs.

+Q2.4.5: I get a cryptic error message when trying to do something.
+------------------------------------------------------------------
+
+When I try to use some particular option of some particular package, I
+get a cryptic error message in the minibuffer.
+
+ If the message went by too quickly, use `Help->Recent Messages' from
+the menubar (or type `C-h l') to see recent messages.
+
+ If you can't figure out what's going on, select
+`Options->Troubleshooting->Debug on Error' from the menubar (or type
+`M-:' then `(setq debug-on-error t)') then try and make the error
+happen again. This will put in the debugger (you can get out of this
+and continue what you were doing before by typing `c') and give you a
+backtrace that may be enlightening. If not, try reading through this
+FAQ; if that fails, you could try posting to `comp.emacs.xemacs'
+(making sure to include the backtrace) and someone may be able to help.
+If you can identify which XEmacs Lisp source file the error is coming
+from you can get a more detailed stack backtrace by doing the following:
+
+ 1. Visit the .el file in an XEmacs buffer.
+
+ 2. Issue the command `M-x eval-current-buffer'.

+Q2.4.6: XEmacs hangs when I try to do something.
+------------------------------------------------
+
+XEmacs might just be slow; some operations take a long time. XEmacs
+may also be waiting on a response from the network, for example when
+you are trying to send mail.
+
+ You can usually interrupt XEmacs by typing `C-g'. If not (for
+example, Lisp code explicitly disabled this by setting `inhibit-quit'),
+you can use the "critical quit" mechanism by typing `Control-Shift-G'.
+This should also pop you into the debugger and give you a backtrace,
+which can tell you where the problem is (*note How to debug an XEmacs
+problem with a debugger: Q2.4.4.). (Note that setting `debug-on-quit'
+or selecting `Options->Troubleshooting->Debug on Quit' will also cause
+regular `C-g' to enter the debugger and give you a backtrace.)
+
+ If you can't interrupt XEmacs this way, or for some reason XEmacs is
+not talking to the keyboard, you can try sending the `SIGINT' signal
+using the `kill' command.
+
+ If the Lisp backtrace isn't enlightening, or if XEmacs is so hung
+that you can't interrupt it at all, you could try attaching to the
+process and getting a C stack backtrace. *Note How to debug an XEmacs
+problem with a debugger: Q2.4.4.

+
+Q2.4.7: I get an error message when XEmacs is running in batch mode.
+--------------------------------------------------------------------
+
+Typically this happens when you are trying to compile some Elisp code.
+If you are doing this as part of XEmacs or the XEmacs packages, you
+should automatically get a backtrace, which can help you determine the
+source of the problem. In other cases, you can get equivalent results
+by setting the environment variable `XEMACSDEBUG' to `(setq
+stack-trace-on-error t load-always-display-messages t
+load-ignore-out-of-date-elc-files t load-show-full-path-in-messages t)'
+(this needs to be all on one line; to set an environment variable, use
+`export XEMACSDEBUG='FOO'' under `bash', `zsh', etc. or `setenv
+XEMACSDEBUG 'FOO'' under `csh' and `tcsh'). `XEMACSDEBUG' specifies
+Lisp code that will be executed at startup time.
+
+ If the backtrace is not sufficiently useful in helping you diagnose
+the problem, you should consider using a debugger such as GDB. *Note
+How to debug an XEmacs problem with a debugger: Q2.4.4. You probably
+want to set a breakpoint on `signal_1'. Since such errors often occur
+during compiling, which is often triggered by a complex command run
+from a make suite, it may be easier to attach to the process once it's
+running.
+
+ Under Microsoft Windows (and perhaps other operating systems), there
+is another useful trick you can do if you have configured with debugging
+support (configure option `--debug' (`--with-debug' in 21.5) or setting
+`DEBUG_XEMACS' in `nt/config.inc'). Set the environment variable
+`XEMACSDEBUG' (as described above) to `(setq debug-on-error t)'. Then,
+when an error occurs noninteractively, instead of trying to invoke the
+Lisp debugger (which obviously won't work), XEmacs will break out to a
+C debugger using `(force-debugging-signal t)'. _NOTE_: This runs
+`abort()'!!! (As well as and after executing INT 3 under MS Windows,
+which should invoke a debugger if it's active.) This is guaranteed to
+kill XEmacs! (But in this situation, XEmacs is about to die anyway, and
+if no debugger is present, this will usefully dump core.)

+
+Q2.4.8: The keyboard or mouse is not working properly, or I have some other event-related problem.
+--------------------------------------------------------------------------------------------------
+
+XEmacs has various facilities for debugging event handling.
+
+ First, try setting the variable `debug-emacs-events' to non-zero.
+This will output various information showing which events are being
+received and how they are being translated. This may show you, for
+example, that a key command is getting intercepted using
+`key-translation-map'; this problem can otherwise be very tricky to
+debug.
+
+ Under X, you can see exactly which events are being received from the
+window system by setting `x-debug-events' to non-zero. (The value `1'
+gives you regular output, and `2' gives you verbose output, including
+all parameters.)
+
+ A similar facility exists under MS Windows: Set
+`debug-mswindows-events' to non-zero. (The value `1' gives you regular
+output. The value `2' gives you verbose output, including all
+parameters. The value `3' gives you super-gorily-detailed output.)

+
+Q2.4.9: `C-g' doesn't work for me. Is it broken?
+-------------------------------------------------
+
+`C-g' does work for most people in most circumstances. If it doesn't,
+there are two possible explanations:
+
+ 1. XEmacs is hung in a way that prevents `C-g' from working. This
+ can happen when code is wrapped with a binding of `inhibit-quit'
+ to `t'; you should still be able interrupt XEmacs using "critical
+ quit". On the other hand, XEmacs may be seriously wedged. (If
+ you're lucky, sending `SIGINT' to the XEmacs process will
+ interrupt it.) *Note XEmacs hangs when I try to do something.:
+ Q2.4.6.
+
+ 2. `C-g' is indeed broken on your system. To test, try executing
+ `(while t)' from the `*scratch*' buffer. If `C-g' doesn't
+ interrupt, then it's broken. This used to happen with systems
+ where `SIGIO' was broken, but `BROKEN_SIGIO' wasn't defined.
+ However, there may not be very many such systems nowadays.

+
+Q2.4.10: How do I debug process-related problems?
+-------------------------------------------------
+
+Under MS Windows, you can set the variable
+`debug-mswindows-process-command-lines' to non-`nil' to get information
+on exactly what is getting passed to a process. This can be useful in
+determining problems with quoting. (Under Unix, a process receives each
+argument separately, but under MS Windows a single command line is
+received, and arguments with spaces or other special characters in them
+must be quoted. Unfortunately this means that each process,
+potentially at least, has its own quoting conventions, and the code to
+process quoting conventions in `cmd.exe', the Visual C++ startup code
+and the like is baroque and poorly documented. XEmacs uses the variable
+`mswindows-construct-process-command-line-alist' to construct a command
+line from a list of arguments based on the command to be run, but it is
+(and cannot be) a perfect solution.)

+Q2.5.2 Startup problems related to paths or package locations.
+--------------------------------------------------------------

+ If something is still going wrong, or you get a startup warning about

+on the path-searching process at startup by setting the environment
+variable `EMACSDEBUGPATHS' to a non-null value. One thing to look for
+if you're having package problems is the value of
+`configure-package-path'. This corresponds to what was compiled into
+XEmacs using the `--package-prefix' or `--package-path' parameter
+(*note Q2.1.1::). If this has the value of `nil', this means that no

+
+Q2.5.6: XEmacs 21.1 on Windows used to spawn an ugly console window on every startup. Has that been fixed?
+-----------------------------------------------------------------------------------------------------------
+
+Yes.
+
+ The console was there because `temacs' (and in turn, `xemacs') was a
+console application, and Windows typically creates a new console for a
+console process unless the creating process requests that one isn't
+created. This used to be fixed with `runemacs', a small Windows
+application that existed merely to start `xemacs', stating that it
+didn't want a console.
+
+ XEmacs 21.4 fixes this cleanly by the virtue of being a true "GUI"
+application. The explanation of what that means is included for
+educational value.
+
+ When building an application to be run in a Win32 environment, you
+must state which sub-system it is to run in. Valid subsystems include
+"console" and "gui". The subsystem you use affects the run time
+libraries linked into your application, the start up function that is
+run before control is handed over to your application, the entry point
+to your program, and how Windows normally invokes your program. (Console
+programs automatically get a console created for them at startup if
+their stdin/stdout don't point anywhere useful, which is the case when
+run from the GUI. This is a stupid design, of course - instead, the
+console should get created only when the first I/O actually occurs!
+GUI programs have an equally stupid design: When called from
+`CMD.EXE'/`COMMAND.COM', their stdin/stdout will be set to point
+nowhere useful, even though the command shell has its own stdin/stdout.
+It's as if someone who had learned a bit about stdio but had no actual
+knowledge of interprocess communication designed the scheme;
+unfortunately, the whole process-communication aspect of the Win32 API
+is equally badly designed.) For example, the entry point for a console
+app is "main" (which is what you'd expect for a C/C++ program), but the
+entry point for a "gui" app is "WinMain". This confuses and annoys a
+lot of programmers who've grown up on Unix systems, where the kernel
+doesn't really care whether your application is a gui program or not.
+
+ For reasons not altogether clear, and are lost in the mists of time
+and tradition, XEmacs on Win32 started out as a console application, and
+therefore a console was automatically created for it. (It may have been
+made a console application partly because a console is needed in some
+circumstances, especially under Win95, to interrupt, terminate, or send
+signals to a child process, and because of the bogosity mentioned above
+with GUI programs and the standard command shell. Currently, XEmacs
+just creates and immediately hides a console when necessary, and works
+around the "no useful stdio" problem by creating its own console window
+as necessary to display messages in.)

+
+Q3.0.2: How can I bind complex functions (or macros) to keys?
+-------------------------------------------------------------
+
+As an example, say you want the `paste' key on a Sun keyboard to insert
+the current Primary X selection at point. You can accomplish this with:
+
+ (define-key global-map [f18] 'x-insert-selection)
+
+ However, this only works if there is a current X selection (the
+selection will be highlighted). The functionality I like is for the
+`paste' key to insert the current X selection if there is one,
+otherwise insert the contents of the clipboard. To do this you need to
+pass arguments to `x-insert-selection'. This is done by wrapping the
+call in a 'lambda form:
+
+ (global-set-key [f18]
+ (lambda () (interactive) (x-insert-selection t nil)))
+
+ This binds the f18 key to a "generic" functional object. The
+interactive spec is required because only interactive functions can be
+bound to keys.
+
+ For the FAQ example you could use:
+
+ (global-set-key [(control ?.)]
+ (lambda () (interactive) (scroll-up 1)))
+ (global-set-key [(control ?;)]
+ (lambda () (interactive) (scroll-up -1)))
+
+ This is fine if you only need a few functions within the lambda body.
+If you're doing more it's cleaner to define a separate function. *Note

+Q3.0.4: Globally binding `Delete'?
+----------------------------------
+
+I cannot manage to globally bind my `Delete' key to something other
+than the default. How does one do this?
+
+ Answer: The problem is that many modes explicitly bind `Delete'. To
+get around this, try the following:
+
+ (defun foo ()
+ (interactive)
+ (message "You hit DELETE"))
+
+ (define-key key-translation-map 'delete 'redirected-delete)

+----------------------------------------------------------
+
+The following works in GNU Emacs 19:
+
+ (global-set-key [help] 'help-command);; Help
+
+ The following works in XEmacs with the addition of shift:
+
+ (global-set-key [(shift help)] 'help-command);; Help
+
+ But it doesn't work alone. This is in the file `PROBLEMS' which
+should have come with your XEmacs installation: _Emacs ignores the
+`help' key when running OLWM_.
+
+ OLWM grabs the `help' key, and retransmits it to the appropriate
+client using `XSendEvent'. Allowing Emacs to react to synthetic events
+is a security hole, so this is turned off by default. You can enable
+it by setting the variable `x-allow-sendevents' to t. You can also
+cause fix this by telling OLWM to not grab the help key, with the null
+binding `OpenWindows.KeyboardCommand.Help:'.

+Q3.0.6: How can you type in special characters in XEmacs?
+---------------------------------------------------------
+
+One way is to use the package `x-compose'. Then you can use sequences
+like `Compose " a' to get ä, etc.
+
+ Another way is to use the `iso-insert' package. Then you can use
+sequences like `C-x 8 " a' to get ä, etc.
+
+ Glynn Clements <glynn@sensei.co.uk> writes:
+
+ It depends upon your X server.
+
+ Generally, the simplest way is to define a key as Multi_key with
+ xmodmap, e.g.
+ xmodmap -e 'keycode 0xff20 = Multi_key'
+
+ You will need to pick an appropriate keycode. Use xev to find out
+ the keycodes for each key.
+
+ [NB: On a `Windows' keyboard, recent versions of XFree86
+ automatically define the right `Windows' key as Multi_key'.]
+
+ Once you have Multi_key defined, you can use e.g.
+ Multi a ' => á
+ Multi e " => ë
+ Multi c , => ç
+
+ etc.
+
+ Also, recent versions of XFree86 define various AltGr-<key>
+ combinations as dead keys, i.e.
+ AltGr [ => dead_diaeresis
+ AltGr ] => dead_tilde

+ (add-hook 'text-mode-hook 'turn-on-auto-fill)
+
+ *WARNING*: note that changing the value of `default-major-mode' from
+`fundamental-mode' can break a large amount of built-in code that
+expects newly created buffers to be in `fundamental-mode'. (Changing
+from `fundamental-mode' to `text-mode' might not wreak too much havoc,
+but changing to something more exotic like a lisp-mode would break many
+Emacs packages).
+
+ Note that Emacs by default starts up in buffer `*scratch*' in
+`initial-major-mode', which defaults to `lisp-interaction-mode'. Thus
+adding the following form to your Emacs init file will cause the
+initial `*scratch*' buffer to be put into auto-fill'ed `text-mode':
+
+ (setq initial-major-mode
+ (lambda ()
+ (text-mode)
+ (turn-on-auto-fill)))
+
+ Note that after your init file is loaded, if
+`inhibit-startup-message' is `nil' (the default) and the startup buffer
+is `*scratch*' then the startup message will be inserted into
+`*scratch*'; it will be removed after a timeout by erasing the entire
+`*scratch*' buffer. Keep in mind this default usage of `*scratch*' if
+you desire any prior manipulation of `*scratch*' from within your Emacs
+init file. In particular, anything you insert into `*scratch*' from
+your init file will be later erased. Also, if you change the mode of
+the `*scratch*' buffer, be sure that this will not interfere with
+possible later insertion of the startup message (e.g. if you put
+`*scratch*' into a nonstandard mode that has automatic font lock rules,
+then the startup message might get fontified in a strange foreign
+manner, e.g. as code in some programming language).

+---------------------------------------------------------------
+
+I want to change things so that if I select some text and start typing,

+
+ You want to use something called "pending delete". Pending delete
+is what happens when you select a region (with the mouse or keyboard)
+and you press a key to replace the selected region by the key you typed.
+Usually backspace kills the selected region.
+
+ To get this behavior, ensure that you have the `pc' package
+installed, and add the following lines to your `init.el':
+
+ (cond
+ ((fboundp 'turn-on-pending-delete)
+ (turn-on-pending-delete))
+ ((fboundp 'pending-delete-on)
+ (pending-delete-on t)))

+
+Q3.3.5: Why is killing so slow?
+-------------------------------
+
+This actually is an X Windows question, although you'll notice it with
+keyboard operations as well as while using the GUI. Basically, there
+are four ways to communicate interprogram via the X server:
+
+*Primary selection*
+ a transient selection that gets replaced every time a new
+ selection is made
+
+*Secondary selection*
+ for "exchanging" with the primary selection
+
+*Cut buffers*
+ a clipboard internal to the X server (deprecated)
+
+*Clipboard selection*
+ a selection with a notification protocol that allows a separate
+ app to manage the clipboard
+
+ The cut buffers are deprecated because managing them is even more
+inefficient than the clipboard notification protocol. The primary
+selection works fine for many users and applications, but is not very
+robust under intensive or sophisticated use.
+
+ In Motif and MS Windows, a clipboard has become the primary means for
+managing cut and paste. These means that "modern" applications tend to
+be oriented toward a true clipboard, rather than the primary selection.
+(On Windows, there is nothing equivalent to the primary selection.)
+It's not that XEmacs doesn't support the simple primary selection
+method, it's that more and more other applications don't.
+
+ So the slowdown occurs because XEmacs now engages in the clipboard
+notification protocol on _every_ kill. This is especially slow on
+Motif.
+
+ With most people running most clients and server on the same host,
+and many of the rest working over very fast communication, you may
+expect that the situation is not going to improve.
+
+ There are a number of workarounds. The most effective is to use a
+special command to do selection ownership only when you intend to paste
+to another application. Useful commands are `kill-primary-selection'
+and `copy-primary-selection'. These work only on text selected with
+the mouse (probably; experiment), and are bound by default to the `Cut'
+and `Copy', respectively, buttons on the toolbar.
+`copy-primary-selection' is also bound to `C-Insert'. You can yank the
+clipboard contents with `yank-primary-selection', bound to the `Paste'
+toolbar button and `Sh-Insert'.
+
+ If you are communicating by cut and paste with applications that use
+the primary selection, then you can customize
+`interprogram-cut-function' to `nil', restoring the XEmacs version 20
+behavior. How can you tell if a program will support this?
+Motifly-correct programs require the clipboard; you lose. For others,
+only by trying it. You also need to customize the complementary
+`interprogram-paste-function' to `nil'. (Otherwise XEmacs-to-XEmacs
+pastes will not work correctly.)
+
+ You may get some relief on Motif by setting
+`x-selection-strict-motif-ownership' to nil, but this means you will
+only intermittently be able to paste XEmacs kills to Motif applications.
+

+will immediately complete its operation. In other words, it will only
+delay for a second if you let it.

+Q3.4.2: How do you make XEmacs indent CL if-clauses correctly?
+--------------------------------------------------------------
+
+I'd like XEmacs to indent all the clauses of a Common Lisp `if' the
+same amount instead of indenting the 3rd clause differently from the
+first two.
+
+ The package `cl-indent' that comes with XEmacs sets up this kind of
+indentation by default. `cl-indent' also knows about many other
+CL-specific forms. To use `cl-indent', one can do this:
+
+ (setq lisp-indent-function 'common-lisp-indent-function)
+
+ One can also customize `cl-indent.el' so it mimics the default `if'
+indentation `then' indented more than the `else'. Here's how:
+
+ (put 'if 'common-lisp-indent-function '(nil nil &body))

+Q4.0.1: How do I specify a font?
+--------------------------------
+
+#### Update me.
+
+ In 21.4 and above, you can use the `Options' menu to change the font.
+You can also do it in your init file, e.g. like this (for MS Windows):
+
+ (set-face-font 'default "Lucida Console:Regular:10")
+ (set-face-font 'modeline "MS Sans Serif:Regular:10")

+
+Q4.0.2: How do I set the text, menu and modeline fonts?
+-------------------------------------------------------
+
+#### Update me.
+
+ Note that you should use `Emacs.' and not `Emacs*' when setting face
+values.
+
+ In `.Xresources':
+
+ Emacs.default.attributeFont: -*-*-medium-r-*-*-*-120-*-*-m-*-*-*
+ Emacs*menubar*font: fixed
+ Emacs.modeline.attributeFont: fixed
+
+ This is confusing because `default' and `modeline' are face names,
+and can be found listed with all faces in the current mode by using
+`M-x set-face-font (enter) ?'. They use the face-specific resource
+`attributeFont'.
+
+ On the other hand, `menubar' is a normal X thing that uses the
+resource `font'. With Motif it _may be_ necessary to use `fontList'
+_instead of_ `font'. In _non-Motif_ configurations with Mule it _is_
+necessary to use `fontSet' instead of `font'. (Sorry, there just is no
+simple recipe here.)

+
+ Emacs.zmacs-region.attributeForeground: firebrick

+----------------------------------------
+
+I'm using Netscape (or another color grabber like XEmacs); is there any
+way to limit the number of available colors in the color map?
+
+ Answer: No, but you can start Netscape before XEmacs, and it will use
+the closest available color if the colormap is full. You can also limit
+the number of colors Netscape uses, using the flags -mono, -ncols <#> or
+-install (for mono, limiting to <#> colors, or for using a private color
+map).
+
+ If you have the money, another solution would be to use a truecolor
+or direct color video.

+-----------------------------------------------------------
+
+XEmacs tries to automatically determine whether your tty supports color,

+------------------------------------------------
+
+Juan Villacis <jvillaci@wahnsinnig.extreme.indiana.edu> writes:
+
+ There are several ways to do it. For example, you could specify a
+ default pixmap image to use in your `~/.Xresources', e.g.,
+
+ Emacs*EmacsFrame.default.attributeBackgroundPixmap: /path/to/image.xpm
+
+ and then reload ~/.Xresources and restart XEmacs. Alternatively,
+ since each face can have its own pixmap background, a better way
+ would be to set a face's pixmap within your XEmacs init file, e.g.,
+
+ (set-face-background-pixmap 'default "/path/to/image.xpm")

+
+Q4.0.8: How do I display non-ASCII characters?
+----------------------------------------------
+
+If you're using a Mule-enabled XEmacs, then display is automatic. If
+you're not seeing the characters you expect, either (1) you don't have
+appropriate fonts available or (2) XEmacs did not correctly detect the
+coding system (*note Recognize Coding: (xemacs)Recognize Coding.). In
+case (1), install fonts as is customary for your platform. In case
+(2), you need to tell XEmacs explicitly what coding systems you're
+using. *Note Specify Coding: (xemacs)Specify Coding.
+
+ If your XEmacs is not Mule-enabled, and for some reason getting a
+Mule-enabled XEmacs seems like the wrong thing to do, all is not lost.
+You can arrange it by brute force. In `event-Xt.c' (suppress the urge
+to look in this file--play Doom instead, because you'll survive
+longer), it is written:
+
+ In a non-Mule world, a user can still have a multi-lingual editor,
+ by doing `(set-face-font "-*-iso8859-2" (current-buffer))' for all
+ their Latin-2 buffers, etc.
+
+ For the related problem of _inputting_ non-ASCII characters in a
+non-Mule XEmacs, *Note How can you type in special characters in
+XEmacs?: Q3.0.6.

+Q4.1.1: How can I do source code highlighting using font-lock?
+--------------------------------------------------------------
+
+For most modes, font-lock is already set up and just needs to be turned
+on. This can be done by adding the line:
+
+ (require 'font-lock)
+
+ to your `init.el'. (You can turn it on for the current buffer and
+session only by `M-x font-lock-mode'.) See the file
+`etc/sample.init.el' (`etc/sample.emacs' in XEmacs versions prior to
+21.4) for more information.

+Q4.2.4: How can I change the modeline color based on the mode used?
+-------------------------------------------------------------------
+
+You can use something like the following:
+
+ (add-hook 'lisp-mode-hook
+ (lambda ()
+ (set-face-background 'modeline "red" (current-buffer))))
+
+ Then, when editing a Lisp file (i.e. when in Lisp mode), the modeline
+colors change from the default set in your `init.el'. The change will
+only be made in the buffer you just entered (which contains the Lisp
+file you are editing) and will not affect the modeline colors anywhere
+else.
+
+ Notes:
+
+ * The hook is the mode name plus `-hook'. eg. c-mode-hook,
+ c++-mode-hook, emacs-lisp-mode-hook (used for your `init.el' or a
+ `xx.el' file), lisp-interaction-mode-hook (the `*scratch*' buffer),
+ text-mode-hook, etc.
+
+ * Be sure to use `add-hook', not `(setq c-mode-hook xxxx)',
+ otherwise you will erase anything that anybody has already put on
+ the hook.
+
+ * You can also do `(set-face-font 'modeline FONT)', eg.
+ `(set-face-font 'modeline "*bold-r-normal*140-100-100*"
+ (current-buffer))' if you wish the modeline font to vary based on
+ the current mode.
+
+ There are additional modeline faces, `modeline-buffer-id',
+`modeline-mousable', and `modeline-mousable-minor-mode', which you may
+want to customize.

+------------------------------------------------------------
+
+I am trying to use a resource like `Emacs*menubar*font' to set the font
+of the menubar but it's not working.
+
+ In Motif, the use of `font' resources is obsoleted in order to
+support internationalization. If you are using the real Motif menubar,
+this resource is not recognized at all; you have to say:
+
+ Emacs*menubar*fontList: FONT
+
+ If you are using the Lucid menubar, for backward compatibility with
+existing user configurations, the `font' resource is recognized. Since
+this is not supported by Motif itself, the code is a kludge and the
+`font' resource will be recognized only if the `fontList' resource
+resource is unset. This means that the resource
+
+ *fontList: FONT
+
+ will override
+
+ Emacs*menubar*font: FONT
+
+ even though the latter is more specific.
+
+ In non-Motif configurations using `--with-mule' and `--with-xfs' it
+_is_ necessary to use the `fontSet' resource _instead of_ the `font'
+resource. The backward compatibility kludge was never implemented for
+non-Motif builds. Example:
+
+ *fontSet: FONT

+Q4.6.4: Moving the scrollbar can move the point; can I disable this?
+--------------------------------------------------------------------
+
+When I move the scrollbar in an XEmacs window, it moves the point as
+well, which should not be the default behavior. Is this a bug or a
+feature? Can I disable it?
+
+ The current behavior is a feature, not a bug. Point remains at the
+same buffer position as long as that position does not scroll off the
+screen. In that event, point will end up in either the upper-left or
+lower-left hand corner.
+
+ This cannot be changed.

+Q4.6.5: Scrolling one line at a time.
+-------------------------------------
+
+Can the cursor keys scroll the screen a line at a time, rather than the
+default half page jump? I tend it to find it disorienting.
+
+ Use the following:
+
+ (setq scroll-step 1)
+
+ You can also change this with Customize. Select from the `Options'
+menu `Advanced (Customize)->Emacs->Environment->Windows->Scroll Step...'

+Q4.6.6: How can I turn off automatic horizontal scrolling in specific modes?
+----------------------------------------------------------------------------
+
+Do `(setq truncate-lines t)' in the mode-hooks for any modes in which
+you want lines truncated.
+
+ More precisely: If `truncate-lines' is nil, horizontal scrollbars
+will never appear. Otherwise, they will appear only if the value of
+`scrollbar-height' for that buffer/window/etc. is non-zero. If you do
+
+ (set-specifier scrollbar-height 0)
+
+ then horizontal scrollbars will not appear in truncated buffers
+unless the package specifically asked for them.

+-------------------------------------------------------------------
+
+`auto-show-mode' controls whether or not a horizontal scrollbar
+magically appears when a line is too long to be displayed. This is
+enabled by default. To turn it off, put the following in your
+`init.el':
+
+ (setq auto-show-mode nil)

+
+Q5.0.1: Where is a list of X resources?
+---------------------------------------
+
+Search through the `NEWS' file for `X Resources'. A fairly
+comprehensive list is given after it.
+
+ In addition, an `app-defaults' file `etc/Emacs.ad' is supplied,
+listing the defaults. The file `etc/sample.Xresources' gives a
+different set of defaults that you might consider for installation in
+your `~/.Xresources' file. It is nearly the same as `etc/Emacs.ad',
+but a few entries are altered. Be careful about installing the
+contents of this file into your `.Xresources' (or legacy `.Xdefaults')
+file if you use GNU Emacs under X11 as well.

+
+I'd like the icon to just say `XEmacs', and not include the name of the

+-------------------------------------------------------------------
+
+I'd like to have the window title area display the full directory/name
+of the current buffer file and not just the name.
+
+ Add the following line to your `init.el':
+
+ (setq frame-title-format "%S: %f")
+
+ A more sophisticated title might be:
+
+ (setq frame-title-format
+ '("%S: " (buffer-file-name "%f"

+
+Q5.0.5: `xemacs -name junk' doesn't work?
+-----------------------------------------
+
+When I run `xterm -name junk', I get an xterm whose class name
+according to xprop, is `junk'. This is the way it's supposed to work,
+I think. When I run `xemacs -name junk' the class name is not set to
+`junk'. It's still `emacs'. What does `xemacs -name' really do? The
+reason I ask is that my window manager (fvwm) will make a window sticky
+and I use XEmacs to read my mail. I want that XEmacs window to be
+sticky, without having to use the window manager's function to set the
+window sticky. What gives?
+
+ `xemacs -name' sets the application name for the program (that is,
+the thing which normally comes from `argv[0]'). Using `-name' is the
+same as making a copy of the executable with that new name. The
+`WM_CLASS' property on each frame is set to the frame-name, and the
+application-class. So, if you did `xemacs -name FOO' and then created
+a frame named BAR, you'd get an X window with WM_CLASS = `( "BAR",
+"Emacs")'. However, the resource hierarchy for this widget would be:
+
+ Name: FOO .shell .container .BAR
+ Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
+
+ instead of the default
+
+ Name: xemacs.shell .container .emacs
+ Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
+
+ It is arguable that the first element of WM_CLASS should be set to
+the application-name instead of the frame-name, but I think that's less
+flexible, since it does not give you the ability to have multiple frames
+with different WM_CLASS properties. Another possibility would be for
+the default frame name to come from the application name instead of
+simply being `emacs'. However, at this point, making that change would
+be troublesome: it would mean that many users would have to make yet
+another change to their resource files (since the default frame name
+would suddenly change from `emacs' to `xemacs', or whatever the
+executable happened to be named), so we'd rather avoid it.
+
+ To make a frame with a particular name use:
+
+ (make-frame '((name . "the-name")))

+
+Q5.1.1: Does XEmacs rename all the `win32-*' symbols to `w32-*'?
+----------------------------------------------------------------
+
+In his flavor of Emacs 20, Richard Stallman has renamed all the
+`win32-*' symbols to `w32-*'. Does XEmacs do the same?
+
+ We consider such a move counter-productive, thus we do not use the
+`w32' prefix. (His rather questionable justification was that he did
+not consider Windows to be a "winning" platform.) However, the name
+`Win32' is not particularly descriptive outside the Windows world, and
+using just `windows-' would be too generic. So we chose a compromise,
+the prefix `mswindows-' for Windows-related variables and functions.
+
+ Thus all the XEmacs variables and functions directly related to
+either the Windows GUI or OS are prefixed `mswindows-' (except for a
+couple of debugging variables, prefixed `debug-mswindows-'). From an
+architectural perspective, however, we believe that this is mostly a
+non-issue because there should be a very small number of
+window-systems-specific variables anyway. Whenever possible, we try to
+provide generic interfaces that apply to all window systems.

+
+Associating a new file type with XEmacs.
+........................................
+
+In Explorer select `View->Options->File Types', press `[New Type...]'
+and fill in the dialog box, e.g.:
+
+ Description of type: Emacs Lisp source
+ Associated extension: el
+ Content Type (MIME): text/plain
+
+ then press `[New...]' and fill in the `Action' dialog box as follows:
+
+ Action:
+ Open
+
+ Application used to perform action:
+ D:\Full\path\for\xemacs.exe "%1"
+
+ [x] Use DDE
+
+ DDE Message:

+
+ Application:
+ <leave blank>
+
+ DDE Application Not Running:
+ <leave blank>
+
+ Topic:
+ <leave blank>
+
+Associating an existing file type with XEmacs.
+..............................................
+
+In Explorer select `View->Options->File Types'. Click on the file type
+in the list and press `[Edit...]'. If the file type already has an
+`Open' action, double click on it and fill in the `Action' dialog box
+as described above; otherwise create a new action.
+
+ If the file type has more than one action listed, you probably want
+to make the `Open' action that you just edited the default by clicking
+on it and pressing `Set Default'.
+
+ Note for Windows 2000 users: Under Windows 2000, get to `File Types'
+using `Control Panel->Folder Options->File Types'.

+5.2: Printing

+
+Q5.2.1: What do I need to change to make printing work?
+-------------------------------------------------------
+
+For regular printing there are two variables that can be customized.
+
+`lpr-command'
+ This should be set to a command that takes standard input and sends
+ it to a printer. Something like:
+
+ (setq lpr-command "lp")
+
+`lpr-switches'
+ This should be set to a list that contains whatever the print
+ command requires to do its job. Something like:
+
+ (setq lpr-switches '("-depson"))
+
+ For postscript printing there are three analogous variables to
+customize.
+
+`ps-lpr-command'
+ This should be set to a command that takes postscript on standard
+ input and directs it to a postscript printer.
+
+`ps-lpr-switches'
+ This should be set to a list of switches required for
+ `ps-lpr-command' to do its job.
+
+`ps-print-color-p'
+ This boolean variable should be set `t' if printing will be done in
+ color, otherwise it should be set to `nil'.
+
+ NOTE: It is an undocumented limitation in XEmacs that postscript
+printing (the `Pretty Print Buffer' menu item) *requires* a window
+system environment. It cannot be used outside of X11.

+Q5.2.2: How can I print WYSIWYG a font-locked buffer?
+-----------------------------------------------------
+
+Font-lock looks nice. How can I print (WYSIWYG) the highlighted
+document?
+
+ The package `ps-print', which is now included with XEmacs, provides
+the ability to do this. The source code contains complete instructions
+on its use, in
+`$prefix/lib/xemacs/xemacs-packages/lisp/ps-print/ps-print.el', being
+the default location of an installed ps-print package.

+Q5.2.3: Getting `M-x lpr' to work with postscript printer.
+----------------------------------------------------------
+
+My printer is a Postscript printer and `lpr' only works for Postscript
+files, so how do I get `M-x lpr-region' and `M-x lpr-buffer' to work?
+
+ Put something like this in your `init.el':
+
+ (setq lpr-command "a2ps")
+ (setq lpr-switches '("-p" "-1"))
+
+ If you don't use a2ps to convert ASCII to postscript (why not, it's
+free?), replace with the command you do use. Note also that some
+versions of a2ps require a `-Pprinter' to ensure spooling.

+---------------------------------------
+
+As of 21.4, printing works on Windows, using simply `File->Print

+
+ Prior to 21.4, there is no built-in support, but there are some

+--------------------------------------
+
+"Network Audio System" (NAS) is a client-server sound library for X.

+ `http://radscan.com/nas.html'.
+
+ To build XEmacs with it, use the `configure' flag `--with-sound=nas'
+(`--enable-sound=nas' in 21.5 or later).
+
+ "Enlightened Sound Daemon" (ESD or EsounD) is yet another sound
+system.
+
+ `http://www.tux.org/~ricdude/EsounD.html'.
+
+ To build XEmacs with it, use the `configure' flag `--with-sound=esd'
+(`--enable-sound=esd' in 21.5 or later).
+
+ You can specify support for both with a flag like
+`--with-sound=nas,esd' (`--enable-sound=nas,esd' in 21.5 or later).

+ M-x shell RET
+
+ This will then start a second shell. The key is that no buffer named
+`*shell*' can exist. It might be preferable to use `M-x
+rename-uniquely' to rename the `*shell*' buffer instead of `M-x
+rename-buffer'.
+
+ Alternately, you can set the variable `shell-multiple-shells'. If
+the value of this variable is non-nil, each time shell mode is invoked,

+ Use `M-x rsh' or `M-x telnet' to open remote sessions rather than

+Q5.5.3: How do I disable gnuserv from opening a new frame?
+----------------------------------------------------------
+
+If you set the `gnuserv-frame' variable to the frame that should be
+used to display buffers that are pulled up, a new frame will not be
+created. For example, you could put
+
+ (setq gnuserv-frame (selected-frame))
+
+ early on in your `init.el', to ensure that the first frame created
+is the one used for your gnuserv buffers.
+
+ There is an option to set the gnuserv target to the current frame.
+See `Options->Display->"Other Window" Location->Make Current Frame
+Gnuserv Target'
+
+ You can also change this with Customize. Select from the `Options'
+menu `Advanced (Customize)->Emacs->Environment->Gnuserv->Gnuserv
+Frame...' or type `M-x customize <RET> gnuserv <RET>'.

+--------------------------------------------------------------------------
+
+Put the following in your `init.el' file to start the server:
+
+ (gnuserv-start)
+
+ Start your first XEmacs as usual. After that, you can do:
+
+ gnuclient randomfilename
+
+ from the command line to get your existing XEmacs process to open a
+new frame and visit randomfilename in that window. When you're done
+editing randomfilename, hit `C-x #' to kill the buffer and get rid of
+the frame.

+
+Q6.0.2: How can I send mail?
+----------------------------
+
+Under Unix and Mac OS X, the `sendmail' package is normally used for
+this. #### Write me.
+
+ Under Windows, you need to use `smtpmail', which communicates
+directly with the mail server, as there is no `sendmail' program
+running. To get it working, use code like the following in your
+`init.el' file:
+
+ ;; Get mail working under Windows.
+ (setq message-send-mail-function 'smtpmail-send-it) ; for message/Gnus
+ (setq send-mail-function 'smtpmail-send-it) ; for C-x m, etc.
+ ;; the following ensures that mail problems can be debugged: it logs a trace
+ ;; of the SMTP conversation to *trace of SMTP session to <somewhere>*.
+ (setq smtpmail-debug-info t)
+ ;; Substitute your info here.
+ ;(setq user-mail-address "ben@xemacs.org")
+ ;(setq user-full-name "Ben Wing")
+ ;(setq smtpmail-default-smtp-server "smtp.myserver.myisp.com")
+ ;; The following two aren't completely necessary but may help.
+ ;(setq smtpmail-local-domain "666.com")
+ ;(setq smtpmail-sendto-domain "666.com")
+ ;; If your SMTP server requires a username/password to authenticate, as
+ ;; many do nowadays, set them like this:
+ ;(setq smtpmail-auth-credentials ; or use ~/.authinfo
+ ; '(("smtp.myserver.myisp.com" 25 "USER@SOMEWHERE" "PASSWORD")))
+
+ ;; Other possibilities for getting smtpmail to work:
+ ;;
+ ;; If for some reason you need to authenticate using the STARTTLS protocol
+ ;; (don't look into this unless you know what it is), use
+ ;; (setq smtpmail-starttls-credentials
+ ;; '(("YOUR SMTP HOST" 25 "~/.my_smtp_tls.key" "~/.my_smtp_tls.cert")))
+ ;; Requires external program
+ ;; ftp://ftp.opaopa.org/pub/elisp/starttls-*.tar.gz.
+ ;; See http://www.ietf.org/rfc/rfc2246.txt,
+ ;; http://www.ietf.org/rfc/rfc2487.txt
+
+ The lines you need to care about are those that set
+`user-mail-address', `user-full-name', `smtpmail-default-smtp-server',
+and `smtpmail-auth-credentials'. You need to set these with,
+respectively, your email address, your full name, the SMTP server you
+use for outgoing mail, and the username and password you need to log in
+to your SMTP server. (If for some reason your SMTP server doesn't
+require logging in to send mail, don't uncomment this last line.)
+
+ The other settings may be useful in specific cases, but you should
+know what you're doing before enabling them.

+
+Q6.0.8: An MUA gets an error incorporating new mail.
+----------------------------------------------------
+
+rmail and VM, and probably other MUA's as well, get new mail from your
+mailbox (called `/var/mail/$USER' or `/var/spool/mail/$USER' or
+something similar) using a program called `movemail'. This program
+interlocks with `/bin/mail' using the protocol defined by `/bin/mail'.
+
+ There are various different protocols in general use, which you need
+to specify using the `--mail-locking' option (`--with-mail-locking' in
+21.5 or later) to `configure':
+
+`lockf'
+ POSIX file locking with `lockf()'
+
+`flock'
+ BSD file locking with `flock()'
+
+`dot'
+ To manipulate mail file `foo', first create file `foo.lock'
+
+`locking'
+ Use `locking()', Microsoft's renamed `flock()'
+
+`mmdf'
+ Use `lk_open()' and `lk_close()' as defined by the Multi-channel
+ Memo Distribution Facility
+
+`pop'
+ Retrieve mail using POP (the Post Office Protocol). This is the
+ default for Cygwin/MinGW.
+
+ *IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR
+SYSTEM, YOU CAN LOSE MAIL!*
+
+ Usually the value is correctly determined automatically: `configure'
+tries to detect the method in use, and defaults exist on systems for
+which this doesn't work.
+
+ However, if you run into problems incorporating new mail, it may be
+because an incorrect method is being used.
+
+ If your system uses the lock file protocol, and permissions are set
+so that ordinary users cannot write lock files in the mail spool
+directory, you may need to make `movemail' setgid to a suitable group
+such as `mail'. You can use these commands (as root):
+
+ chgrp mail movemail
+ chmod 2755 movemail
+
+ If you are using the `pop' locking method, `movemail' must be setuid
+root.
+
+ Installation normally copies movemail from the build directory to an
+installation directory which is usually under `/usr/local/lib'. The
+installed copy of `movemail' is usually in the directory
+`/usr/local/lib/xemacs-VERSION/TARGET' (for example,
+`/usr/local/lib/xemacs-21.4.15/i686-pc-cygwin'). You must change the
+group and mode of the installed copy; changing the group and mode of
+the build directory copy is ineffective.

+
+*Note Q6.0.8::.
+

+use the `movemail' installed with your XEmacs. Failure to do so can

+-----------------------------------------------------
+
+Firstly there is an ftp site which describes X-faces and has the
+associated tools mentioned below, at
+`http://ftp.cs.indiana.edu/pub/faces/'.
+
+ Then the steps are
+
+ 1. Create 48x48x1 bitmap with your favorite tool
+
+ 2. Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,
+ and then compile the face.
+
+ 3. cat file.xbm | xbm2ikon |compface > file.face
+
+ 4. Then be sure to quote things that are necessary for emacs strings:
+
+ cat ./file.face | sed 's/\\/\\\\/g'
+ | sed 's/\"/\\\"/g' > ./file.face.quoted
+
+ 5. Then set up emacs to include the file as a mail header - there
+ were a couple of suggestions here--either something like:
+
+ (setq mail-default-headers
+ "X-Face: <Ugly looking text string here>")
+
+ Or, alternatively, as:
+
+ (defun mail-insert-x-face ()
+ (save-excursion
+ (goto-char (point-min))
+ (search-forward mail-header-separator)
+ (beginning-of-line)
+ (insert "X-Face:")
+ (insert-file-contents "~/.face")))
+
+ (add-hook 'mail-setup-hook 'mail-insert-x-face)
+
+ However, 2 things might be wrong:
-Q2.0.1: Running XEmacs without installing
------------------------------------------
+ Some versions of pbmtoicon produces some header lines that is not
+expected by the version of compface that I grabbed. So I found I had to
+include a `tail +3' in the pipeline like this:
- How can I just try XEmacs without installing it?
+ cat file.xbm | xbm2ikon | tail +3 |compface > file.face
- XEmacs will run in place without requiring installation and copying
-of the Lisp directories, and without having to specify a special
-build-time flag. It's the copying of the Lisp directories that
-requires so much space. XEmacs is largely written in Lisp.
+ Some people have also found that if one uses the `(insert-file)'
+method, one should NOT quote the face string using the sed script .
- A good method is to make a shell alias for xemacs:
+ It might also be helpful to use Stig's <stig@hackvan.com> script
+xbm2face (included in the compface distribution at XEmacs.org) to do the
+conversion.
- alias xemacs=/i/xemacs-20.2/src/xemacs
+ Contributors for this item:
- (You will obviously use whatever directory you downloaded the source
-tree to instead of `/i/xemacs-20.2').

--------------------------
+Q6.1.1: How do I set up VM to retrieve mail from a remote site using POP?
+-------------------------------------------------------------------------
- The space required by the installation directories can be reduced
-dramatically if desired. Gzip all the .el files. Remove all the
-packages you'll never want to use. Remove the TexInfo manuals. Remove
-the Info (and use just hardcopy versions of the manual). Remove most
-of the stuff in etc. Remove or gzip all the source code. Gzip or
-remove the C source code. Configure it so that copies are not made of
-the support lisp.
+Use `vm-spool-files', like this for example:
- These are all Emacs Lisp source code and bytecompiled object code.
-You may safely gzip everything named *.el here. You may remove any
-package you don't use. _Nothing bad will happen if you delete a package
-that you do not use_. You must be sure you do not use it though, so be
-conservative at first.
+ (setq vm-spool-files '("/var/spool/mail/wing"
+ "netcom23.netcom.com:110:pass:wing:MYPASS"))
- Possible candidates for deletion include w3, games, hyperbole, mh-e,
-hm-html-menus, vm, viper, oobr, gnus, etc. Ask yourself, _Do I ever
-want to use this package?_ If the answer is no, then it is a candidate
-for removal.
+ Of course substitute your actual password for MYPASS.
- First, gzip all the .el files. Then go about package by package and
-start gzipping the .elc files. Then run XEmacs and do whatever it is
-you normally do. If nothing bad happens, then delete the directory. Be
-conservative about deleting directories, and it would be handy to have a
-backup around in case you get too zealous.

+Yes. Of course XEmacs can use any network file system (such as NFS or
+Windows file sharing) you have available, and includes some
+optimizations and safety features appropriate to those environments.
+
+ It is also possible to transparently edit files via FTP, ssh, or
+rsh. That is, XEmacs makes a local copy using the transport in the
+background, and automatically refreshes the remote original from that
+copy when you save it. XEmacs also is capable of doing file system
+manipulations like creating and removing directories and files. The
+FTP interface is provided by the standard `efs' package *Note EFS:
+(efs)Top. The ssh/rsh interface is provided by the optional `tramp'
+package *Note TRAMP: (tramp)Top.

+-------------------------------------------
+
+How can `init.el' determine which of the family of Emacsen I am using?
+
+ To determine if you are currently running GNU Emacs 18, GNU Emacs 19,
+XEmacs 19, XEmacs 20, or Epoch, and use appropriate code, check out the
+example given in `etc/sample.init.el' (`etc/sample.emacs' in XEmacs
+versions prior to 21.4). There are other nifty things in there as well!
+
+ For all new code, all you really need to do is:
+
+ (defvar running-xemacs (string-match "XEmacs\\|Lucid" emacs-version))

+--------------------------------------------------
+
+I know I can evaluate Elisp expressions from `*scratch*' buffer with
+`C-j' after the expression. How do I do it from another buffer?
+
+ Press `M-:' (the default binding of `eval-expression'), and enter
+the expression to the minibuffer.

+-------------------------------------------
+
+If you put `(setq tab-width 6)' in your `init.el' file it does not
+work! Is there a reason for this? If you do it at the EVAL prompt it
+works fine!! How strange.
+

+Q7.0.4: How can I add directories to the `load-path'?
+-----------------------------------------------------
+
+Here are two ways to do that, one that puts your directories at the
+front of the load-path, the other at the end:
- `prim', `modes', `packages', and `utils' are four directories you
-definitely do *not* want to delete, although certain packages can be
-removed from them if you do not use them.
+ ;;; Add things at the beginning of the load-path, do not add
+ ;;; duplicate directories:
+ (pushnew "bar" load-path :test 'equal)
- Online texinfo sources in the `info' can either be compressed them
-or remove them. In either case, `C-h i' (info mode) will no longer
-work.
+ (pushnew "foo" load-path :test 'equal)
+
+ ;;; Add things at the end, unconditionally
+ (setq load-path (nconc load-path '("foo" "bar")))

+Q7.0.5: How to check if a lisp function is defined?
+---------------------------------------------------
+
+Use the following elisp:
+
+ (fboundp 'foo)
+
+ It's almost always a mistake to test `emacs-version' or any similar
+variables.
+
+ Instead, use feature-tests, such as `featurep', `boundp', `fboundp',
+or even simple behavioral tests, eg.:
+
+ (defvar foo-old-losing-code-p
+ (condition-case nil (progn (losing-code t) nil)
+ (wrong-number-of-arguments t)))
+
+ There is an incredible amount of broken code out there which could
+work much better more often in more places if it did the above instead
+of trying to divine its environment from the value of one variable.

+
+Q7.0.6: Can I force the output of `(face-list)' to a buffer?
+------------------------------------------------------------
+
+It would be good having it in a buffer, as the output of `(face-list)'
+is too wide to fit to a minibuffer.
+
+ Evaluate the expression in the `*scratch*' buffer with point after
+the rightmost paren and typing `C-j'.
+
+ If the minibuffer smallness is the only problem you encounter, you
+can simply press `C-h l' to get the former minibuffer contents in a
+buffer.

+
+Q7.1.1: What is the difference in key sequences between XEmacs and GNU Emacs?
+-----------------------------------------------------------------------------
+
+Erik Naggum <clerik@naggum.no> writes;
+
+ Emacs has a legacy of keyboards that produced characters with
+ modifier bits, and therefore map a variety of input systems into
+ this scheme even today. XEmacs is instead optimized for X events.
+ This causes an incompatibility in the way key sequences are
+ specified, but both Emacs and XEmacs will accept a key sequence as
+ a vector of lists of modifiers that ends with a key, e.g., to bind
+ `M-C-a', you would say `[(meta control a)]' in both Emacsen.
+ XEmacs has an abbreviated form for a single key, just (meta
+ control a). Emacs has an abbreviated form for the Control and the
+ Meta modifiers to string-characters (the ASCII characters), as in
+ `\M-\C-a'. XEmacs users need to be aware that the abbreviated
+ form works only for one-character key sequences, while Emacs users
+ need to be aware that the string-character is rather limited.
+ Specifically, the string-character can accommodate only 256
+ different values, 128 of which have the Meta modifier and 128 of
+ which have not. In each of these blocks, only 32 characters have
+ the Control modifier. Whereas `[(meta control A)]' differs from
+ `[(meta control a)]' because the case differs, `\M-\C-a' and
+ `\M-\C-A' do not. Programmers are advised to use the full common
+ form, both because it is more readable and less error-prone, and
+ because it is supported by both Emacsen.
+
+ Another (even safer) way to be sure of the key-sequences is to use
+the `read-kbd-macro' function, which takes a string like `C-c <up>',
+and converts it to the internal key representation of the Emacs you
+use. The function is available both on XEmacs and GNU Emacs.

+
+Q7.1.2: Can I generate "fake" keyboard events?
+----------------------------------------------
+
+I wonder if there is an interactive function that can generate "fake"
+keyboard events. This way, I could simply map them inside XEmacs.
+
+ This seems to work:
+
+ (defun cg--generate-char-event (ch)
+ "Generate an event, as if ch has been typed"
+ (dispatch-event (character-to-event ch)))
+
+ ;; Backspace and Delete stuff
+ (global-set-key [backspace]
+ (lambda () (interactive) (cg--generate-char-event 127)))
+ (global-set-key [unknown_keysym_0x4]
+ (lambda () (interactive) (cg--generate-char-event 4)))
+
+\1f
+File: xemacs-faq.info, Node: Q7.1.3, Next: Q7.1.4, Prev: Q7.1.2, Up: Advanced
+
+Q7.1.3: Could you explain `read-kbd-macro' in more detail?
+----------------------------------------------------------
+
+The `read-kbd-macro' function returns the internal Emacs representation
+of a human-readable string (which is its argument). Thus:
+
+ (read-kbd-macro "C-c C-a")
+ => [(control ?c) (control ?a)]
+
+ (read-kbd-macro "C-c C-. <up>")
+ => [(control ?c) (control ?.) up]
+
+ In GNU Emacs the same forms will be evaluated to what GNU Emacs
+understands internally--the sequences `"\C-x\C-c"' and `[3 67108910
+up]', respectively.
+
+ The exact "human-readable" syntax is defined in the docstring of
+`edmacro-mode'. I'll repeat it here, for completeness.
+
+ Format of keyboard macros during editing:
+
+ Text is divided into "words" separated by whitespace. Except for
+ the words described below, the characters of each word go directly
+ as characters of the macro. The whitespace that separates words is
+ ignored. Whitespace in the macro must be written explicitly, as in
+ `foo <SPC> bar <RET>'.
+
+ * The special words `RET', `SPC', `TAB', `DEL', `LFD', `ESC',
+ and `NUL' represent special control characters. The words
+ must be written in uppercase.
+
+ * A word in angle brackets, e.g., `<return>', `<down>', or
+ `<f1>', represents a function key. (Note that in the standard
+ configuration, the function key `<return>' and the control key
+ <RET> are synonymous.) You can use angle brackets on the
+ words <RET>, <SPC>, etc., but they are not required there.
+
+ * Keys can be written by their ASCII code, using a backslash
+ followed by up to six octal digits. This is the only way to
+ represent keys with codes above \377.
+
+ * One or more prefixes `M-' (meta), `C-' (control), `S-'
+ (shift), `A-' (alt), `H-' (hyper), and `s-' (super) may
+ precede a character or key notation. For function keys, the
+ prefixes may go inside or outside of the brackets: `C-<down>'
+ == `<C-down>'. The prefixes may be written in any order:
+ `M-C-x' == `C-M-x'.
+
+ Prefixes are not allowed on multi-key words, e.g., `C-abc',
+ except that the Meta prefix is allowed on a sequence of
+ digits and optional minus sign: `M--123' == `M-- M-1 M-2 M-3'.
+
+ * The `^' notation for control characters also works: `^M' ==
+ `C-m'.
+
+ * Double angle brackets enclose command names: `<<next-line>>'
+ is shorthand for `M-x next-line <RET>'.
+
+ * Finally, `REM' or `;;' causes the rest of the line to be
+ ignored as a comment.
+
+ Any word may be prefixed by a multiplier in the form of a decimal
+ number and `*': `3*<right>' == `<right> <right> <right>', and
+ `10*foo' == `foofoofoofoofoofoofoofoofoofoo'.
+
+ Multiple text keys can normally be strung together to form a word,
+ but you may need to add whitespace if the word would look like one
+ of the above notations: `; ; ;' is a keyboard macro with three
+ semicolons, but `;;;' is a comment. Likewise, `\ 1 2 3' is four
+ keys but `\123' is a single key written in octal, and `< right >'
+ is seven keys but `<right>' is a single function key. When in
+ doubt, use whitespace.

+Q7.1.4: What is the performance hit of `let'?
+---------------------------------------------
+
+In most cases, not noticeable. Besides, there's no avoiding `let'--you
+have to bind your local variables, after all. Some pose a question
+whether to nest `let's, or use one `let' per function. I think because
+of clarity and maintenance (and possible future implementation),
+`let'-s should be used (nested) in a way to provide the clearest code.

+
+Q7.1.5: What is the recommended use of `setq'?
+----------------------------------------------
+
+ * Global variables
+
+ You will typically `defvar' your global variable to a default
+ value, and use `setq' to set it later.
+
+ It is never a good practice to `setq' user variables (like
+ `case-fold-search', etc.), as it ignores the user's choice
+ unconditionally. Note that `defvar' doesn't change the value of a
+ variable if it was bound previously. If you wish to change a
+ user-variable temporarily, use `let':
+
+ (let ((case-fold-search nil))
+ ... ; code with searches that must be case-sensitive
+ ...)
+
+ You will notice the user-variables by their docstrings beginning
+ with an asterisk (a convention).
+
+ * Local variables
+
+ Bind them with `let', which will unbind them (or restore their
+ previous value, if they were bound) after exiting from the `let'
+ form. Change the value of local variables with `setq' or whatever
+ you like (e.g. `incf', `setf' and such). The `let' form can even
+ return one of its local variables.
+
+ Typical usage:
+
+ ;; iterate through the elements of the list returned by
+ ;; `hairy-function-that-returns-list'
+ (let ((l (hairy-function-that-returns-list)))
+ (while l
+ ... do something with (car l) ...
+ (setq l (cdr l))))
+
+ Another typical usage includes building a value simply to work
+ with it.
+
+ ;; Build the mode keymap out of the key-translation-alist
+ (let ((inbox (file-truename (expand-file-name box)))
+ (i 0))
+ ... code dealing with inbox ...
+ inbox)
+
+ This piece of code uses the local variable `inbox', which becomes
+ unbound (or regains old value) after exiting the form. The form
+ also returns the value of `inbox', which can be reused, for
+ instance:
+
+ (setq foo-processed-inbox
+ (let .....))

+
+Q7.1.6: What is the typical misuse of `setq'?
+---------------------------------------------
+
+A typical misuse is probably `setq'ing a variable that was meant to be
+local. Such a variable will remain bound forever, never to be
+garbage-collected. For example, the code doing:
+
+ (defun my-function (whatever)
+ (setq a nil)
+ ... build a large list ...
+ ... and exit ...)
+
+ does a bad thing, as `a' will keep consuming memory, never to be
+unbound. The correct thing is to do it like this:
+
+ (defun my-function (whatever)
+ (let (a) ; default initialization is to nil
+ ... build a large list ...
+ ... and exit, unbinding `a' in the process ...)
+
+ Not only is this prettier syntactically, but it makes it possible for
+Emacs to garbage-collect the objects which `a' used to reference.
+
+ Note that even global variables should not be `setq'ed without
+`defvar'ing them first, because the byte-compiler issues warnings. The
+reason for the warning is the following:
+
+ (defun flurgoze nil) ; ok, global internal variable
+ ...
+
+ (setq flurghoze t) ; ops! a typo, but semantically correct.
+ ; however, the byte-compiler warns.
+
+ While compiling toplevel forms:
+ ** assignment to free variable flurghoze

+
+Q7.1.7: I like the `do' form of cl, does it slow things down?
+-------------------------------------------------------------
+
+It shouldn't. Here is what Dave Gillespie has to say about cl.el
+performance:
+
+ Many of the advanced features of this package, such as `defun*',
+ `loop', and `setf', are implemented as Lisp macros. In
+ byte-compiled code, these complex notations will be expanded into
+ equivalent Lisp code which is simple and efficient. For example,
+ the forms
+
+ (incf i n)
+ (push x (car p))
+
+ are expanded at compile-time to the Lisp forms
+
+ (setq i (+ i n))
+ (setcar p (cons x (car p)))
+
+ which are the most efficient ways of doing these respective
+ operations in Lisp. Thus, there is no performance penalty for
+ using the more readable `incf' and `push' forms in your compiled
+ code.
+
+ _Interpreted_ code, on the other hand, must expand these macros
+ every time they are executed. For this reason it is strongly
+ recommended that code making heavy use of macros be compiled. (The
+ features labelled "Special Form" instead of "Function" in this
+ manual are macros.) A loop using `incf' a hundred times will
+ execute considerably faster if compiled, and will also
+ garbage-collect less because the macro expansion will not have to
+ be generated, used, and thrown away a hundred times.
+
+ You can find out how a macro expands by using the `cl-prettyexpand'
+ function.

+Q7.1.8: I like recursion, does it slow things down?
+---------------------------------------------------
+
+Yes. The Emacs byte-compiler cannot do much to optimize recursion. But

+slowness comes from internal mechanisms such as redisplay, or from the
+fact that it is an interpreter.
+
+ Please try not to make your code much uglier to gain a very small
+speed gain. It's not usually worth it.

+Q7.1.9: How do I put a glyph as annotation in a buffer?
+-------------------------------------------------------
+
+Here is a solution that will insert the glyph annotation at the
+beginning of buffer:
+
+ (make-annotation (make-glyph '([FORMAT :file FILE]
+ [string :data "fallback-text"]))
+ (point-min)
+ 'text
+ (current-buffer))
+
+ Replace `FORMAT' with an unquoted symbol representing the format of
+the image (e.g. `xpm', `xbm', `gif', `jpeg', etc.) Instead of `FILE',
+use the image file name (e.g.
+`/usr/local/lib/xemacs-21.4/etc/recycle.xpm').
+
+ You can turn this to a function (that optionally prompts you for a
+file name), and inserts the glyph at `(point)' instead of `(point-min)'.

+Q7.1.10: `map-extents' won't traverse all of my extents!
+--------------------------------------------------------
+
+I tried to use `map-extents' to do an operation on all the extents in a
+region. However, it seems to quit after processing a random number of
+extents. Is it buggy?
+
+ No. The documentation of `map-extents' states that it will iterate
+across the extents as long as FUNCTION returns `nil'. Unexperienced
+programmers often forget to return `nil' explicitly, which results in
+buggy code. For instance, the following code is supposed to delete all
+the extents in a buffer, and issue as many `fubar!' messages.
+
+ (map-extents (lambda (ext ignore)
+ (delete-extent ext)
+ (message "fubar!")))
+
+ Instead, it will delete only the first extent, and stop right there -
+because `message' will return a non-nil value. The correct code is:
+
+ (map-extents (lambda (ext ignore)
+ (delete-extent ext)
+ (message "fubar!")

+
+Q7.2.1: What are bignums, ratios, and bigfloats in Lisp?
+--------------------------------------------------------
+
+Thanks to Jerry James <james@xemacs.org>, XEmacs 21.5.18 and later can
+use the capabilities of multiple-precision libraries that may be
+available for your platform. The GNU Multiple Precision (GMP) and BSD
+Multiple Precision (MP) libraries are partially supported. GMP gives
+you "bignums" (arbitrary precision integers), "ratios" (arbitrary
+precision fractions), and "bigfloats" (arbitrary precision floating
+point numbers). GNU MP is better-supported by XEmacs at the time of
+writing (2004-04-06). BSD MP support does not include ratios or
+bigfloats, and it throws errors that aren't understood.
+
+ In most cases, bignum support should be transparent to users and Lisp
+programmers. A bignum-enabled XEmacs will automatically convert from
+fixnums to bignums and back in pure integer arithmetic, and for GNU MP,
+from floats to bigfloats. (Bigfloats must be explicitly coerced to
+other types, even if they are exactly representable by less precise
+types.) The Lisp reader and printer have been enhanced to handle
+bignums, as have the mathematical functions. Rationals (fixnums,
+bignums, and ratios) are printed using the `%d', `%o', `%x', and `%u'
+format conversions. The read syntax for ratios is `3/5'.
+
+ User-visible changes in behavior include (in probable order of
+annoyance)
+
+ * Arithmetic can cause a segfault, depending on your MP library
+ *Note XEmacs segfaults when I use very big numbers!: Q7.2.2.
+
+ * Terminology is not Common-Lisp-conforming. For example, "integer"
+ for Emacs Lisp means what Common Lisp calls "fixnum". This issue
+ is being investigated, but the use of "integer" for fixnum is
+ pervasive and may cause backward-compatibility and
+ GNU-Emacs-compatibility problems.
+
+ * Many operations that used to cause a range error now succeed, with
+ intermediate results and return values coerced to bignums as
+ needed.
+
+ * An atom with ratio read syntax now returns a number, not a symbol.
+
+ * The `%u' format conversion will now give an error if its argument
+ is negative. (Without MP, it prints a number which Lisp can't
+ read.)

-Q2.0.3: Compiling XEmacs with Netaudio.
----------------------------------------
-
- What is the best way to compile XEmacs with the netaudio system,
-since I have got the netaudio system compiled but installed at a weird
-place, I am not root. Also in the READMEs it does not say anything
-about compiling with the audioserver?
-
- You should only need to add some stuff to the configure command line.
-To tell it to compile in netaudio support: `--with-sound=both', or
-`--with-sound=nas' if you don't want native sound support for some
-reason.) To tell it where to find the netaudio includes and libraries:
-
- --site-libraries=WHATEVER
- --site-includes=WHATEVER
-
- Then (fingers crossed) it should compile and it will use netaudio if
-you have a server running corresponding to the X server. The netaudio
-server has to be there when XEmacs starts. If the netaudio server goes
-away and another is run, XEmacs should cope (fingers crossed, error
-handling in netaudio isn't perfect).
-
- BTW, netaudio has been renamed as it has a name clash with something
-else, so if you see references to NAS or Network Audio System, it's the
-same thing. It also might be found at
-`ftp://ftp.x.org/contrib/audio/nas/'.

-Q2.0.5: Do I need X11 to run XEmacs?
-------------------------------------
+GMP by default allocates temporaries on the stack. If you run out of
+stack space, you're dead; there is no way that we know of to reliably
+detect this condition, because `alloca' is typically implemented to be
+_fast_ rather than robust. If you just need a little more oomph, use a
+bigger stack (_e.g._, the `ulimit -s' command in bash(1)). If you want
+robustness at the cost of speed, configure GMP with `--disable-alloca'
+and rebuild the GMP library.
- No. The name "XEmacs" is unfortunate in the sense that it is *not*
-an X Window System-only version of Emacs. XEmacs has full color
-support on a color-capable character terminal.
+ We do not know whether BSD MP uses `alloca' or not. Please send any

+---------------------------------------------
- Christopher Davis <ckd@loiosh.kei.com> writes:
+AUCTeX is a complex and sophisticated editing package dedicated to TeX

+files, and of course shortcuts for entering common TeX macros, LaTeX
+environments, etc, and for fontlock.
- That's correct [The SunOS 4.1.3 precompiled binaries don't do name
- lookup]. Since Sun figured that everyone used NIS to do name
- lookups (that DNS thing was apparently only a passing fad,
- right?), the stock SunOS 4.x systems don't have DNS-based name
- lookups in libc.
+ AUCTeX is a standard package provided by XEmacs. You can get it as
+usual through the `M-x list-packages' interface. It is also included
+in the (non-Mule) SUMO package. The AUCTeX XEmacs package is
+maintained by Uwe Brauer <GET MAIL ADDRESS>.
- This is also why Netscape ships two binaries for SunOS 4.1.x.
-
- The best solution is to compile it yourself; the configure script
- will check to see if you've put DNS in the shared libc and will
- then proceed to link against the DNS resolver library code.
+ AUCTeX is extremely complicated, and its developers primarily use
+GNU Emacs. Not all features of the bleeding edge version of AUCTeX are

------------------------------------------
+File: xemacs-faq.info, Node: Q8.1.1, Next: Q8.1.2, Prev: Q8.0.4, Up: Other Packages
- First of all, don't panic. Whenever XEmacs crashes, it tries
-extremely hard to auto-save all of your files before dying. (The main
-time that this will not happen is if the machine physically lost power
-or if you killed the XEmacs process using `kill -9'). The next time
-you try to edit those files, you will be informed that a more recent
-auto-save file exists. You can use `M-x recover-file' to retrieve the
-auto-saved version of the file.
+Q8.1.1: Is there a reason for an Emacs package not to be included in XEmacs?
+----------------------------------------------------------------------------
- You can use the command `M-x recover-session' after a crash to pick
-up where you left off.
+The reason for an Emacs package not to be included in XEmacs is usually
+one or more of the following:
- Now, XEmacs is not perfect, and there may occasionally be times, or
-particular sequences of actions, that cause it to crash. If you can
-come up with a reproducible way of doing this (or even if you have a
-pretty good memory of exactly what you were doing at the time), the
-maintainers would be very interested in knowing about it. Post a
-message to comp.emacs.xemacs or send mail to <crashes@xemacs.org>.
-Please note that the `crashes' address is exclusively for crash reports.
+ 1. The package has not been ported to XEmacs. This will typically
+ happen when it uses GNU-Emacs-specific features, which make it
+ fail under XEmacs.
- If at all possible, include a stack backtrace of the core dump that
-was produced. This shows where exactly things went wrong, and makes it
-much easier to diagnose problems. To do this, you need to locate the
-core file (it's called `core', and is usually sitting in the directory
-that you started XEmacs from, or your home directory if that other
-directory was not writable). Then, go to that directory and execute a
-command like:
+ Porting a package to XEmacs can range from a trivial amount of
+ change to a partial or full rewrite. Fortunately, the authors of
+ modern packages usually choose to support both Emacsen themselves.
- gdb `which xemacs` core
+ 2. The package has been decided not to be appropriate for XEmacs. It
+ may have an equivalent or better replacement within XEmacs, in
+ which case the developers may choose not to burden themselves with
+ supporting an additional package.
- and then issue the command `where' to get the stack backtrace. You
-might have to use `dbx' or some similar debugger in place of `gdb'. If
-you don't have any such debugger available, complain to your system
-administrator.
+ Each package bundled with XEmacs means more work for the
+ maintainers, whether they want it or not. If you are ready to
+ take over the maintenance responsibilities for the package you
+ port, be sure to say so--we will more likely include it.
- It's possible that a core file didn't get produced, in which case
-you're out of luck. Go complain to your system administrator and tell
-him not to disable core files by default. Also *Note Q2.1.15::, for
-tips and techniques for dealing with a debugger.
+ 3. The package simply hasn't been noted by the XEmacs development. If
+ that's the case, the messages like yours are very useful for
+ attracting our attention.
- When making a problem report make sure that:
-
- 1. Report *all* of the information output by XEmacs during the crash.
-
- 2. You mention what O/S & Hardware you are running XEmacs on.
-
- 3. What version of XEmacs you are running.
-
- 4. What build options you are using.
-
- 5. If the problem is related to graphics, we will also need to know
- what version of the X Window System you are running, and what
- window manager you are using.
-
- 6. If the problem happened on a tty, please include the terminal type.
+ 4. The package was noted by the developers, but they simply haven't
+ yet gotten around to including/porting it. Wait for the next
+ release or, even better, offer your help. It will be gladly
+ accepted and appreciated.

-Q2.1.4: Startup warnings about deducing proper fonts?
------------------------------------------------------
-
- How can I avoid the startup warnings about deducing proper fonts?
-
- This is highly dependent on your installation, but try with the
-following font as your base font for XEmacs and see what it does:
-
--adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
-
- More precisely, do the following in your resource file:
-
-Emacs.default.attributeFont: \
--adobe-courier-medium-r-*-*-*-120-*-*-*-*-iso8859-1
-
- If you just don't want to see the `*Warnings*' buffer at startup
-time, you can set this:
-
- (setq display-warning-minimum-level 'error)
-
- The buffer still exists; it just isn't in your face.

+SPARCworks was a development environment from Sun (circa 1993-1996) and
+consisted of compilers (C, C++, FORTRAN 77, Fortran 90, Ada, and
+Pascal), a debugger, and other tools such as TeamWare (for
+configuration management), MakeTool, etc.
-Q2.1.6: XEmacs just locked up my Linux X server!
-------------------------------------------------
+ EOS is the integration of XEmacs with the SPARCworks debugger. It
+allows one to use an XEmacs frame to view code (complete with
+fontification, etc.), set breakpoints, print variables, etc., while
+using the SPARCworks debugger.
- There have been several reports of the X server locking up under
-Linux. In all reported cases removing speedo and scaled fonts from the
-font path corrected the problem. This can be done with the command
-`xset'.
+ EOS stands for "Era on SPARCworks"; Era stood for "Emacs Rewritten
+Again" and was the name used by Sun for its modified version of Lucid
+Emacs (later XEmacs) in the early-mid 90's. This is documented in more
+detail in the history section of the XEmacs About page.
- It is possible that using a font server may also solve the problem.
+ EOS was replaced around 1996 with a newer graphical development
+environment called Sun WorkShop. The current status of this is unknown.

-Q2.1.15: How to Debug an XEmacs problem with a debugger
--------------------------------------------------------
-
- If XEmacs does crash on you, one of the most productive things you
-can do to help get the bug fixed is to poke around a bit with the
-debugger. Here are some hints:
-
- * First of all, if the crash is at all reproducible, consider very
- strongly recompiling your XEmacs with debugging symbols, with no
- optimization, and with the configure options `--debug=yes' and
- `--error-checking=all'. This will make your XEmacs run somewhat
- slower but make it a lot more likely to catch the problem earlier
- (closer to its source), and a lot easier to determine what's going
- on with a debugger.
-
- * If you're able to run XEmacs under a debugger and reproduce the
- crash (if it's inconvenient to do this because XEmacs is already
- running or is running in batch mode as part of a bunch of scripts,
- consider attaching to the existing process with your debugger;
- most debuggers let you do this by substituting the process ID for
- the core file when you invoke the debugger from the command line,
- or by using the `attach' command or something similar), here are
- some things you can do:
-
- * If XEmacs is hitting an assertion failure, put a breakpoint on
- `assert_failed()'.
-
- * If XEmacs is hitting some weird Lisp error that's causing it to
- crash (e.g. during startup), put a breakpoint on
- `signal_1()'--this is declared static in eval.c.
-
- * Internally, you will probably see lots of variables that hold
- objects of type `Lisp_Object'. These are exactly what they appear
- to be, i.e. references to Lisp objects. Printing them out with
- the debugger probably won't be too useful--you'll likely just see
- a number. To decode them, do this:
-
- call debug_print (OBJECT)
-
- where OBJECT is whatever you want to decode (it can be a variable,
- a function call, etc.). This will print out a readable
- representation on the TTY from which the xemacs process was
- invoked.
-
- * If you want to get a Lisp backtrace showing the Lisp call stack,
- do this:
-
- call debug_backtrace ()
-
- * Using `debug_print' and `debug_backtrace' has two disadvantages -
- it can only be used with a running xemacs process, and it cannot
- display the internal C structure of a Lisp Object. Even if all
- you've got is a core dump, all is not lost.
-
- If you're using GDB, there are some macros in the file
- `src/.gdbinit' in the XEmacs source distribution that should make
- it easier for you to decode Lisp objects. This file is
- automatically read by gdb if gdb is run in the directory where
- xemacs was built, and contains these useful macros to inspect the
- state of xemacs:
-
- `pobj'
- Usage: pobj lisp_object
- Print the internal C representation of a lisp object.
-
- `xtype'
- Usage: xtype lisp_object
- Print the Lisp type of a lisp object.
-
- `lbt'
- Usage: lbt
- Print the current Lisp stack trace. Requires a running
- xemacs process.
-
- `ldp'
- Usage: ldp lisp_object
- Print a Lisp Object value using the Lisp printer. Requires a
- running xemacs process.
-
- `run-temacs'
- Usage: run-temacs
- Run temacs interactively, like xemacs. Use this with
- debugging tools (like purify) that cannot deal with dumping,
- or when temacs builds successfully, but xemacs does not.
-
- `dump-temacs'
- Usage: dump-temacs
- Run the dumping part of the build procedure. Use when
- debugging temacs, not xemacs! Use this when temacs builds
- successfully, but xemacs does not.
-
- `check-xemacs'
- Usage: check-xemacs
- Run the test suite. Equivalent to 'make check'.
-
- `check-temacs'
- Usage: check-temacs
- Run the test suite on temacs. Equivalent to 'make
- check-temacs'. Use this with debugging tools (like purify)
- that cannot deal with dumping, or when temacs builds
- successfully, but xemacs does not.
-
- If you are using Sun's `dbx' debugger, there is an equivalent file
- `src/.dbxrc', which defines the same commands for dbx.
-
- * If you're using a debugger to get a C stack backtrace and you're
- seeing stack traces with some of the innermost frames mangled, it
- may be due to dynamic linking. (This happens especially under
- Linux.) Consider reconfiguring with `--dynamic=no'. Also,
- sometimes (again under Linux), stack backtraces of core dumps will
- have the frame where the fatal signal occurred mangled; if you can
- obtain a stack trace while running the XEmacs process under a
- debugger, the stack trace should be clean.
-
- Curtiss <1CMC3466@ibm.mtsac.edu> suggests upgrading to ld.so
- version 1.8 if dynamic linking and debugging is a problem on Linux.
-
- * If you're using a debugger to get a C stack backtrace and you're
- getting a completely mangled and bogus stack trace, it's probably
- due to one of the following:
-
- a. Your executable has been stripped. Bad news. Tell your
- sysadmin not to do this--it doesn't accomplish anything
- except to save a bit of disk space, and makes debugging much
- much harder.
-
- b. Your stack is getting trashed. Debugging this is hard; you
- have to do a binary-search type of narrowing down where the
- crash occurs, until you figure out exactly which line is
- causing the problem. Of course, this only works if the bug
- is highly reproducible.
-
- c. If your stack trace has exactly one frame in it, with address
- 0x0, this could simply mean that XEmacs attempted to execute
- code at that address, e.g. through jumping to a null function
- pointer. Unfortunately, under those circumstances, GDB under
- Linux doesn't know how to get a stack trace. (Yes, this is
- the third Linux-related problem I've mentioned. I have no
- idea why GDB under Linux is so bogus. Complain to the GDB
- authors, or to comp.os.linux.development.system). Again,
- you'll have to use the narrowing-down process described above.
-
- d. You will get a Lisp backtrace output when XEmacs crashes, so
- you'll have something useful.
-
-
- * If you compile with the newer gcc variants gcc-2.8 or egcs, you
- will also need gdb 4.17 or above. Earlier releases of gdb can't
- handle the debug information generated by the newer compilers.
-
- * In versions of XEmacs before 21.2.27, `src/.gdbinit' was named
- `src/gdbinit'. This had the disadvantage of not being sourced
- automatically by gdb, so you had to set that up yourself.

+Q9.0.2: What's new in XEmacs 21.4?
+----------------------------------
- Two things you can do:
+21.4 was the "stable" version of the 21.2 series, which was considered
+"experimental" throughout its life; thus there were no "official"
+releases at all. In essence, XEmacs is now following the "alternating"
+scheme of Linux, where at any point there are at least two different
+development branches, one "stable" and one "experimental". Periodic
+releases happen in both branches, but those in the experimental branch
+are not tested as well, and there's no guarantee they will work at all.
+The experiemental branch is open to any and all code that's acceptable
+to the developers; the stable branch, however, is in general limited
+only to bug fixes, and all contributions are carefully reviewed to make
+sure they will increase and not decrease stability.
- 1) C level:
+ 21.3 never existed at all; it was decided to follow the Linux scheme
+exactly, where odd-numbered series are experimental and even-numbered
+ones stable.
- When you see it going mad like this, you might want to use gdb
- from an 'xterm' to attach to the running process and get a stack
- trace. To do this just run:
+ The following lists summarizes the essential changes made in this
+version. For a fuller list, see the `NEWS' in the `etc' directory of
+the XEmacs distribution, or use `C-h n' or the `Help' menu to view this
+file inside of XEmacs.
- gdb /path/to/xemacs/xemacs ####
+User-visible changes in XEmacs 21.4
+...................................
- Where `####' is the process id of your xemacs, instead of
- specifying the core. When gdb attaches, the xemacs will stop [1]
- and you can type `where' in gdb to get a stack trace as usual. To
- get things moving again, you can just type `quit' in gdb. It'll
- tell you the program is running and ask if you want to quit
- anyways. Say 'y' and it'll quit and have your emacs continue from
- where it was at.
+ * The delete key now deletes forward by default.
- 2) Lisp level:
+ * Shifted motion keys now select text by default.
- Turn on debug-on-quit early on. When you think things are going
- slow hit C-g and it may pop you in the debugger so you can see
- what routine is running. Press `c' to get going again.
+ * You can now build XEmacs with support for GTK+ widget set.
- debug-on-quit doesn't work if something's turned on inhibit-quit
- or in some other strange cases.
+ * ~/.xemacs/init.el is now the preferred location for the init file.
+ (XEmacs now supports a `~/.xemacs/init.el' startup file. Custom
+ file will move to ~/.xemacs/custom.el.)

-File: xemacs-faq.info, Node: Q2.1.23, Next: Q2.1.24, Prev: Q2.1.22, Up: Installation
+ * Much-improved sample init.el, showing how to use many useful
+ features.
-Q2.1.23: Movemail on Linux does not work for XEmacs 19.15 and later.
----------------------------------------------------------------------
+ * XEmacs support for menu accelerators has been much improved.
- Movemail used to work fine in 19.14 but has stopped working in 19.15
-and 20.x. I am using Linux.
+ * Default menubar improvements. (Default menubar has many new
+ commands and better organization. The font-menu is now available
+ under MS Windows.)
- SL Baur <steve@xemacs.org> writes:
+ * Dialog box improvements, including a real file dialog box. (XEmacs
+ now has a proper file dialog box under MS Windows (and GTK)! The
+ old clunky file dialog box is improved. Keyboard traversal now
+ works correctly in MS Windows dialog boxes. There is a Search
+ dialog box available from `Edit->Find...')
- Movemail on Linux used to default to using flock file locking.
- With 19.15 and later versions it now defaults to using `.lock' file
- locking. If this is not appropriate for your system, edit
- src/s/linux.h and uncomment the line that reads:
+ * New buffer tabs.

-Q2.1.24: XEmacs won't start without network. (NEW)
----------------------------------------------------
+ * Printing support now available under MS Windows.
- If XEmacs starts when you're on the network, but fails when you're
-not on the network, you may be missing a "localhost" entry in your
-`/etc/hosts' file. The file should contain an entry like:
+ * Selection improvements. (Kill and yank now interact with the
+ clipboard under Windows. MS Windows support for selection is now
+ much more robust. Motif selection support is now more correct
+ (but slower).)
- 127.0.0.1 localhost
+ * Mail spool locking now works correctly.
- Add that line, and XEmacs will be happy.
+ * International support changes. (The default coding-priority-list
+ is now safer. International keysyms are now supported under X.
+ MS Windows 1251 code page now supported. Czech, Thai,
+ Cyrillic-KOI8, Vietnamese, Ethiopic now supported. Proper support
+ for words in Latin 3 and Latin 4.)

-Q2.1.25:: After upgrading, XEmacs won't do `foo' any more! (NEW)
------------------------------------------------------------------
+ * The modeline's text is now scrollable.
- You have been used to doing `foo', but now when you invoke it (or
-click the toolbar button or select the menu item), nothing (or an error)
-happens. The simplest explanation is that you are missing a package
-that is essential to you. You can either track it down and install it
-(there is a list of packages and brief descriptions of their contents in

- To determine if you are currently running GNU Emacs 18, GNU Emacs 19,
-XEmacs 19, XEmacs 20, or Epoch, and use appropriate code, check out the
-example given in `etc/sample.init.el' (`etc/sample.emacs' in XEmacs
-versions prior to 21.4). There are other nifty things in there as well!
+ * X-Face support is now available under MS Windows.
- For all new code, all you really need to do is:
+ * The PostgreSQL Relational Database Management System is now
+ supported.
- (defvar running-xemacs (string-match "XEmacs\\|Lucid" emacs-version))
+ * Indentation no longer indents comments that begin at column zero.

---------------------------------------------------
+ * New locations for early package hierarchies.
- I know I can evaluate Elisp expressions from `*scratch*' buffer with
-`C-j' after the expression. How do I do it from another buffer?
+ * The `auto-save' library has been greatly improved.
- Press `M-:' (the default binding of `eval-expression'), and enter
-the expression to the minibuffer.

-Q3.0.3: `(setq tab-width 6)' behaves oddly.
--------------------------------------------
+ * Etags changes. See `NEWS' for full details.
- If you put `(setq tab-width 6)' in your `init.el'/`.emacs' file it
-does not work! Is there a reason for this? If you do it at the EVAL
-prompt it works fine!! How strange.

- Here are two ways to do that, one that puts your directories at the
-front of the load-path, the other at the end:
-
- ;;; Add things at the beginning of the load-path, do not add
- ;;; duplicate directories:
- (pushnew "bar" load-path :test 'equal)
-
- (pushnew "foo" load-path :test 'equal)

+
+User-visible changes in XEmacs 21.1
+...................................
+
+ * XEmacs is now supported under Microsoft Windows 95/98 and Windows

+ subscribe to the mailing list at <xemacs-winnt-request@xemacs.org>.
+
+ * XEmacs has been unbundled into constituent installable packages.
+
+ * *Other notable changes*: The `Options' menu has been ported to
+ Custom; XEmacs now is able to choose X visuals and use private
+ colormaps; You can drag the vertical divider of "horizontally"
+ (side-by-side) split windows.
+
+ * *Building changes*: XEmacs can be built with support for 31-bit
+ Lisp integers and 32-bit pointers (previously, it was 28-bit
+ integers and pointers); XEmacs can be built with LDAP support;
+ `dir' files can be removed in the Info subsystem, and will be

+
+ * *New packages*: `imenu', `popper', `gdb-highlight'
+
+ * *Package changes*: Many changes to `cc-mode', `gnus', `gnuclient'.
+ See `NEWS' for full details.
+
+ * *New commands, variables and functions*: `center-to-window-line'
+ (like `recenter' but doesn't force a redisplay); variable
+ `user-full-name' (customize what your full name looks like in
+ mail); `M-x customize-changed-options' (customize options whose

+ add-log-convert' (converts an old-style ChangeLog buffer to
+ new-style); `M-x zap-up-to-char' (like `zap-to-char' but doesn't
+ delete the char searched for); commands to store, retrieve and
+ increment numbers in registers, useful for macros.
+
+ * *Changes to commands, variables, and functions*: `M-x
+ query-replace' and friends operate only on the region when it's
+ active; `echo-keystrokes' can now be a floating-point number; `M-.'
+ searches exact tag matches before inexact ones; function
+ `user-full-name' with no arguments returns the var
+ `user-full-name'; a prefix arg to `M-:' and `C-h c' inserts the
+ result in the current buffer.
+
+ * *Other changes*: Under X, new application class `XEmacs';
+ byte-compilation of user-specs now works.
+
+ * *XEmacs/Mule (internationalization) changes*: Mule support now
+ works on TTY's; Egg/SJ3 input method now officially supported

+ specifiers and symbols whose value is a specifier allowed as
+ modeline specifications.
+
+ * *Frame focus changes*: `focus-follows-mouse' works like FSF,
+ prevents any attempt to permanently change the selected frame; new
+ function `focus-frame' sets the window system focus a frame; new
+ special forms `save-selected-frame' and `with-selected-frame'.
+
+ * *Window function changes*: `select-window' now has optional
+ argument NORECORD to inhibit recording a buffer change;
+ `vertical-motion' now correctly handles optional WINDOW argument
+ and has new optional argument PIXELS, to have the returned values
+ be in pixels; new function `vertical-motion-pixels'; new functions
+ `window-text-area-pixel-{width,height,edges}'; new functions
+ `shrink-window-pixels' and `enlarge-window-pixels'; new function
+ `window-displayed-text-pixel-height'.

+ available, it will be used (better performance on libc6 Linux
+ systems); tracking line-numbers in modeline is now efficient;
+ profiling records a call-count of all called functions,
+ retrievable through `profile-call-count-results'.
+
+ * *Startup and path searching*: code to assemble paths at startup
+ rewritten for new package system; new function `split-path' (splits
+ by `path-separator'); `Info-default-directory-list' obsolete, use
+ `Info-directory-list' instead; site-lisp is deprecated and no
+ longer on the load-path by default.

----------------------------------------------------
+File: xemacs-faq.info, Node: Q9.0.5, Next: Q9.0.6, Prev: Q9.0.4, Up: Current Events
- Use the following elisp:
-
- (fboundp 'foo)
-
- It's almost always a mistake to test `emacs-version' or any similar
-variables.
+Q9.0.5: What's new in XEmacs 20.3?
+----------------------------------
- Instead, use feature-tests, such as `featurep', `boundp', `fboundp',
-or even simple behavioral tests, eg.:
+XEmacs 20.3 was released in November 1997. It contains many bugfixes,
+and a number of new features, including Autoconf 2 based configuration,
+additional support for Mule (Multi-language extensions to Emacs), many
+more customizations, multiple frames on TTY-s, support for multiple info
+directories, an enhanced gnuclient, improvements to regexp matching,
+increased MIME support, and many, many synches with GNU Emacs 20.
- (defvar foo-old-losing-code-p
- (condition-case nil (progn (losing-code t) nil)
- (wrong-number-of-arguments t)))
+ The XEmacs/Mule support has been only seriously tested in a Japanese
+locale, and no doubt many problems still remain. The support for
+ISO-Latin-1 and Japanese is fairly strong. MULE support comes at a
+price--about a 30% slowdown from 19.16. We're making progress on
+improving performance and XEmacs 20.3 compiled without Mule (which is
+the default) is definitely faster than XEmacs 19.16.
- There is an incredible amount of broken code out there which could
-work much better more often in more places if it did the above instead
-of trying to divine its environment from the value of one variable.
+ XEmacs 20.3 is the first non-beta v20 release, and will be the basis
+for all further development.

-Q3.0.6: Can I force the output of `(face-list)' to a buffer?
-------------------------------------------------------------
+Q9.0.6: What's new in XEmacs 20.2?
+----------------------------------
- It would be good having it in a buffer, as the output of
-`(face-list)' is too wide to fit to a minibuffer.
+The biggest changes in 20.2 include integration of EFS (the next
+generation of ange-ftp) and AUC Tex (the Emacs subsystem that includes a
+major mode for editing Tex and LaTeX, and a lot of other stuff). Many
+bugs from 20.0 have been fixed for this release. 20.2 also contains a
+new system for customizing XEmacs options, invoked via `M-x customize'.
- Evaluate the expression in the `*scratch*' buffer with point after
-the rightmost paren and typing `C-j'.
+ XEmacs 20.2 is the development release (20.0 was beta), and is no
+longer considered unstable.
- If the minibuffer smallness is the only problem you encounter, you
-can simply press `C-h l' to get the former minibuffer contents in a
-buffer.
+ For older news, see the file `ONEWS' in the `etc' directory of the

+10 New information about old XEmacsen
+*************************************
- You have to go to Options->Frame Appearance and unselect
- `Frame-Local Font Menu'. If this option is selected, font changes
- are only applied to the _current_ frame and do _not_ get saved
- when you save options.
+This is part 10 of the XEmacs Frequently Asked Questions list. It will
+occasionally be updated to reflect new information about versions which
+are no longer being revised by the XEmacs Project. The primary purpose
+is advice on compatibility of older XEmacsen with new packages and
+updated versions of packages, but bug fixes (which will not be applied
+to released XEmacsen, but users can apply themselves) are also accepted.
- Also, set the following in your `init.el'/`.emacs':

- (setq options-save-faces t)

+ After a bit of sleuthing, I discovered the essence of the problem.
+ For me, the form:
-3.1: X Window System & Resources
-================================
+ (with-temp-buffer
+ (insert-file-contents "foo.xpm")
+ (buffer-string))
-Q3.1.1: Where is a list of X resources?
----------------------------------------
+ returns the empty string. This is because something somewhere
+ replaces the XPM data with a glyph -- I haven't figured out where
+ this occurs.
- Search through the `NEWS' file for `X Resources'. A fairly
-comprehensive list is given after it.
+ Kyle Jones <kyle_jones@wonderworks.com> replies:
- In addition, an `app-defaults' file is supplied, `etc/Emacs.ad'
-listing the defaults. The file `etc/sample.Xdefaults' gives a set of
-defaults that you might consider. It is essentially the same as
-`etc/Emacs.ad' but some entries are slightly altered. Be careful about
-installing the contents of this file into your `.Xdefaults' or
-`.Xresources' file if you use GNU Emacs under X11 as well.

+XEmacs relies on a process called "dumping" to generate a working
+executable. Under MS-Windows this process effectively fixes the memory
+addresses of information in the executable. When XEmacs starts up it
+tries to reserve these memory addresses so that the dumping process can
+be reversed - putting the information back at the correct addresses.
+Unfortunately some .DLLs (for instance the soundblaster driver) occupy
+memory addresses that can conflict with those needed by the dumped
+XEmacs executable. In this instance XEmacs will fail to start without
+any explanation. Note that this is extremely machine specific.
+
+ 21.1.10 includes a fix for this that makes more intelligent guesses
+about which memory addresses will be free, and this should cure the
+problem for most people. 21.4 implements "portable dumping", which
+eliminates the problem altogether. We recommend you use the 21.4
+binaries, but you can use the 21.1 binaries if you are very paranoid
+about stability. *Note Are binaries available?: Q1.1.2.

+3.3 How XEmacs finds Directories and Files
+==========================================
XEmacs deals with a multitude of files during operation. These files
are spread over many directories, and XEmacs determines the location of
of directories which XEmacs searches successively in order to locate a
file.)
-XEmacs Directory Hierarchies
-----------------------------
+3.3.1 XEmacs Directory Hierarchies
+----------------------------------
Many of the files XEmacs looks for are located within the XEmacs
installation itself. However, there are several views of what actually
directory using the shorthand `<root>', it means that XEmacs searches
for it under all hierarchies XEmacs was able to scrounge up. In a
running XEmacs, the hierarchy roots are stored in the variable
-`emacs-roots'.
+`emacs-roots'.
-Package Hierarchies
--------------------
+3.3.2 Package Hierarchies
+-------------------------
Many relevant directories and files XEmacs uses are actually not part of
the core installation. They are part of any of the many packages
Hence, they play a prominent role in the various paths XEmacs sets up.
XEmacs locates packages in any of a number of package hierarchies.
-Package hierarchies fall into three groups: "early", "late", and "last",
-according to the relative location at which they show up in the various
-XEmacs paths. Early package hierarchies are at the very front, late
-ones somewhere in the middle, and last hierarchies are (you guessed it)
-last.

+to the relative location at which they show up in the various XEmacs
+paths. Early package hierarchies are at the very front, late ones

By default, XEmacs expects an early package hierarchy in the
subdirectory `.xemacs/xemacs-packages' of the user's home directory.
There may be any number of package hierarchy directories.
-Directories and Paths
----------------------
+3.3.3 Directories and Paths

Here is a list of the various directories and paths XEmacs tries to
locate during startup. XEmacs distinguishes between directories and

+18 Major Modes
+**************
Emacs has many different "major modes", each of which customizes Emacs
for editing text of a particular sort. The major modes are mutually
modes redefine the syntactical properties of characters appearing in
the buffer. *Note Syntax::.
- The major modes fall into three major groups. Lisp mode (which has
-several variants), C mode, and Muddle mode are for specific programming
-languages. Text mode, Nroff mode, TeX mode, and Outline mode are for
-editing English text. The remaining major modes are not intended for
-use on users' files; they are used in buffers created by Emacs for
-specific purposes and include Dired mode for buffers made by Dired
-(*note Dired::), Mail mode for buffers made by `C-x m' (*note Sending
-Mail::), and Shell mode for buffers used for communicating with an
-inferior shell process (*note Interactive Shell::).
+ The major modes fall into three major groups. Programming modes
+(*note Programs::) are for specific programming languages. Text modes
+(like Nroff mode, TeX mode, Outline mode, XML mode, etc.) are for
+editing human readable text. The remaining major modes are not intended
+for direct use in editing user files; they are used in buffers created
+by Emacs for specific purposes. Examples of such modes include Dired
+mode which is used for buffers made by Dired (*note Dired::), Mail mode
+for buffers made by `C-x m' (*note Sending Mail::), and Shell mode for
+buffers used for communicating with an inferior shell process (*note
+Interactive Shell::).
Most programming language major modes specify that only blank lines
separate paragraphs. This is so that the paragraph commands remain

-Choosing Major Modes
-====================
+18.1 Choosing Major Modes
+=========================
You can select a major mode explicitly for the current buffer, but most
of the time Emacs determines which mode to use based on the file name
previously selected buffer.
\1f
+File: xemacs.info, Node: Mode Hooks, Prev: Choosing Modes, Up: Major Modes
+
+18.2 Mode Hook Variables
+========================
+
+The last step taken by a major mode, by convention, is to invoke a list
+of user supplied functions that are stored in a "hook" variable. This
+allows a user to further customize the major mode, and is particularly
+convenient for setting up buffer local variables (*note Locals::).
+
+ The name of the hook variable is created by appending the string
+`-hook' to the name of the major mode. For example, the hook variable
+used by `text-mode' would be named `text-mode-hook'. By convention the
+mode hook function receives no arguments. If a hook variable does not
+exist, or it has the value `nil', the major mode simply ignores it.
+
+ The recommended way to add functions to a hook variable is with the
+`add-hook' function. For example, to automatically turn on the Auto
+Fill mode when Text mode is invoked the following code can be used in
+the initialization file (*note Init File::)
+
+ (add-hook 'text-mode-hook 'turn-on-auto-fill)
+
+ The `add-hook' function will check that the function is not already
+listed in the hook variable before adding it. It will also create a hook
+variable with the value `nil' if one does not exist before adding the
+function. `add-hook' adds functions to the front of the hook variable
+list. This means that the last hook added is run first by the major
+mode. It is considered very poor style to write hook functions that
+depend on the order that hooks are executed.
+
+ Hooks can be removed from hook variables with `remove-hook'.

-Major Modes for Programming Languages
-=====================================
-
-Emacs has several major modes for the programming languages Lisp,
-Scheme (a variant of Lisp), C, Fortran, and Muddle. Ideally, a major
-mode should be implemented for each programming language you might want
-to edit with Emacs; but often the mode for one language can serve for
-other syntactically similar languages. The language modes that exist
-are those that someone decided to take the trouble to write.
-
- There are several variants of Lisp mode, which differ in the way they
-interface to Lisp execution. *Note Lisp Modes::.
+21.1 Major Modes for Programming Languages
+==========================================
+
+Emacs has several major modes (*note Major Modes::) to support
+programming languages. These major modes will typically understand
+language syntax, provide automatic indentation features, syntax based
+highlighting of text, and will often provide interfaces to the
+programming environment to assist in compiling, executing and debugging
+programs.
+
+ A language mode exist when someone decides to take the trouble to
+write it. At this time many widely used programming languages are
+supported by XEmacs. Examples include Ada, Awk, C, C++, CORBA (IDL),
+Fortran, Java, Lisp, Modula 2, Objective-C, Perl, Pike, Prolog, Python,
+Ruby, Scheme, Simula, SQL, Tcl, Unix Shell scripts, and VHDL. Some of
+these language have seperate manuals, and some times more than one mode
+may be available for a language. For example, there are several
+variants of Lisp mode, which differ in the way they interface to Lisp
+execution. *Note Lisp Modes::.
+
+ Major modes for programming language support are distributed in
+optional XEmacs packages (*note Packages::) that must be installed
+before use. A notable exception to this rule is that a Lisp Mode is
+integral to XEmacs. The Programming Mode Package (`prog-modes')
+contains many such modes. Some languages are supported by packages of
+their own; prominent examples of such packages include `cc-mode' for C,
+C++, Java, Objective C etc., `python-modes' for Python, and `scheme'
+for Scheme.
+
+ For a language named LANG the major mode for the language will
+typically be named `LANG-mode'. For example, the mode for C is called
+`c-mode', that for Bourne shell scripts is called `sh-mode' and so on.
+These modes will invoke the functions listed in the corresponding hook
+variables as a last step. *Note Mode Hooks::.
+
+ A mode can be invoked by typing `M-x LANG-mode <RET>'. However this
+step is not normally required. If the package for a language mode is
+installed XEmacs usually knows when to automatically invoke the mode.
+This is normally done based on examining the file name to determine the
+language. *Note Choosing Modes::.
Each of the programming language modes defines the <TAB> key to run
an indentation function that knows the indentation conventions of that
-language and updates the current line's indentation accordingly. For
-example, in C mode <TAB> is bound to `c-indent-line'. <LFD> is
-normally defined to do <RET> followed by <TAB>; thus it, too, indents
-in a mode-specific fashion.
+language and updates the current line's indentation accordingly. <LFD>
+is normally defined to do <RET> followed by <TAB>; thus it, too,
+indents in a mode-specific fashion.
In most programming languages, indentation is likely to vary from
line to line. So the major modes for those languages rebind <DEL> to
mode, if enabled in a programming language major mode, indents the new
lines which it creates.
- Turning on a major mode calls a user-supplied function called the
-"mode hook", which is the value of a Lisp variable. For example,
-turning on C mode calls the value of the variable `c-mode-hook' if that
-value exists and is non-`nil'. Mode hook variables for other
-programming language modes include `lisp-mode-hook',
-`emacs-lisp-mode-hook', `lisp-interaction-mode-hook',
-`scheme-mode-hook', and `muddle-mode-hook'. The mode hook function
-receives no arguments.

-===============
+21.2 Lists and Sexps
+====================
By convention, Emacs keys for dealing with balanced expressions are
usually `Control-Meta-' characters. They tend to be analogous in
specified number of times; with a negative argument, it moves in the
opposite direction.
- In languages such as C where the comment-terminator can be
-recognized, the sexp commands move across comments as if they were
-whitespace. In Lisp and other languages where comments run until the
-end of a line, it is very difficult to ignore comments when parsing
-backwards; therefore, in such languages the sexp commands treat the
-text of comments as if it were code.
-
Killing an sexp at a time can be done with `C-M-k' (`kill-sexp').
`C-M-k' kills the characters that `C-M-f' would move over.

-Customizing C Indentation
--------------------------
-
-Two variables control which commands perform C indentation and when.
-
- If `c-auto-newline' is non-`nil', newlines are inserted both before
-and after braces that you insert and after colons and semicolons.
-Correct C indentation is done on all the lines that are made this way.
-
- If `c-tab-always-indent' is non-`nil', the <TAB> command in C mode
-does indentation only if point is at the left margin or within the
-line's indentation. If there is non-whitespace to the left of point,
-<TAB> just inserts a tab character in the buffer. Normally, this
-variable is `nil', and <TAB> always reindents the current line.
-
- C does not have anything analogous to particular function names for
-which special forms of indentation are desirable. However, it has a
-different need for customization facilities: many different styles of C
-indentation are in common use.
-
- There are six variables you can set to control the style that Emacs C
-mode will use.
-
-`c-indent-level'
- Indentation of C statements within surrounding block. The
- surrounding block's indentation is the indentation of the line on
- which the open-brace appears.
-
-`c-continued-statement-offset'
- Extra indentation given to a substatement, such as the then-clause
- of an `if' or body of a `while'.
-
-`c-brace-offset'
- Extra indentation for lines that start with an open brace.
-
-`c-brace-imaginary-offset'
- An open brace following other text is treated as if it were this
- far to the right of the start of its line.
-
-`c-argdecl-indent'
- Indentation level of declarations of C function arguments.
-
-`c-label-offset'
- Extra indentation for a line that is a label, case, or default.
-
- The variable `c-indent-level' controls the indentation for C
-statements with respect to the surrounding block. In the example:
-
- {
- foo ();
-
-the difference in indentation between the lines is `c-indent-level'.
-Its standard value is 2.
-
- If the open-brace beginning the compound statement is not at the
-beginning of its line, the `c-indent-level' is added to the indentation
-of the line, not the column of the open-brace. For example,
-
- if (losing) {
- do_this ();
-
-One popular indentation style is that which results from setting
-`c-indent-level' to 8 and putting open-braces at the end of a line in
-this way. Another popular style prefers to put the open-brace on a
-separate line.
-
- In fact, the value of the variable `c-brace-imaginary-offset' is
-also added to the indentation of such a statement. Normally this
-variable is zero. Think of this variable as the imaginary position of
-the open brace, relative to the first non-blank character on the line.
-By setting the variable to 4 and `c-indent-level' to 0, you can get
-this style:
-
- if (x == y) {
- do_it ();
- }
-
- When `c-indent-level' is zero, the statements inside most braces
-line up exactly under the open brace. An exception are braces in column
-zero, like those surrounding a function's body. The statements inside
-those braces are not placed at column zero. Instead, `c-brace-offset'
-and `c-continued-statement-offset' (see below) are added to produce a
-typical offset between brace levels, and the statements are indented
-that far.
-
- `c-continued-statement-offset' controls the extra indentation for a
-line that starts within a statement (but not within parentheses or
-brackets). These lines are usually statements inside other statements,
-like the then-clauses of `if' statements and the bodies of `while'
-statements. The `c-continued-statement-offset' parameter determines
-the difference in indentation between the two lines in:
-
- if (x == y)
- do_it ();
-
-The default value for `c-continued-statement-offset' is 2. Some
-popular indentation styles correspond to a value of zero for
-`c-continued-statement-offset'.
-
- `c-brace-offset' is the extra indentation given to a line that
-starts with an open-brace. Its standard value is zero; compare:
-
- if (x == y)
- {
-
-with:
-
- if (x == y)
- do_it ();
-
-If you set `c-brace-offset' to 4, the first example becomes:
-
- if (x == y)
- {
-
- `c-argdecl-indent' controls the indentation of declarations of the
-arguments of a C function. It is absolute: argument declarations
-receive exactly `c-argdecl-indent' spaces. The standard value is 5 and
-results in code like this:
-
- char *
- index (string, char)
- char *string;
- int char;
-
- `c-label-offset' is the extra indentation given to a line that
-contains a label, a case statement, or a `default:' statement. Its
-standard value is -2 and results in code like this:
-
- switch (c)
- {
- case 'x':
-
-If `c-label-offset' were zero, the same code would be indented as:
-
- switch (c)
- {
- case 'x':
-
-This example assumes that the other variables above also have their
-default values.
-
- Using the indentation style produced by the default settings of the
-variables just discussed and putting open braces on separate lines
-produces clear and readable files. For an example, look at any of the C
-source files of XEmacs.

+21.12 Modes for C, C++, Java and similar languages
+==================================================
+
+The recommended means for supporting the "C-like" programming languages
+in XEmacs is the `cc-mode' package. CC Mode is not included in the
+basic XEmacs distribution but is available as an optional package. If
+loading a file whose names ends in the `.cc' extension does not
+automatically invoke a C++ Mode then the `cc-mode' package is probably
+not yet installed. *Note Packages::.
+
+ CC Mode provides modes for editing source files in Awk (`awk-mode'),
+C (`c-mode'), C++ (`c++-mode'), CORBA IDL (`idl-mode'), Java
+(`java-mode'), Objective C (`objc-mode'), and Pike (`pike-mode'). All
+these languages are supported with an sophisticated "indentation
+engine" that is feature rich, customizable and quite efficient.
+
+ Each language major mode runs hooks in the conventionally named hook
+variables (*note Mode Hooks::). In addition to this conventional
+behavior all the CC Mode major modes will also run hooks in
+`c-mode-common-hook' _before_ invoking the major mode specific hook.
+
+ CC Mode runs any hooks in `c-initialization-hook' exactly once when
+it is first loaded.
+
+ CC Mode is a very comprehensive and flexible system and full
+description of its capabilities is beyond the scope of this manual. It
+is strongly recommended that the reader consult the CC Mode
+documentation for details once the package has been installed. *Note CC
+Mode: (cc-mode)Top.

+
+21.12.1 Older Modes for C and AWK
+---------------------------------
+
+XEmacs provides older versions of a C Mode and an AWK Mode in the
+`prog-modes' package. These older modes do not share the indentation
+engine in CC Mode have have their own specific means of customizing
+indentation. To use these modes the `prog-modes' package must be
+installed.
+
+ This older C mode is known simply as the "Old C Mode". It supports
+only the C language and it lacks many of the features of CC Mode.
+However the old C mode offers modest space requirements and very fast
+operation. Old C Mode might be useful in space constrained
+environments, on slow machines, or for editing very large files. This
+old C mode is available in the `old-c-mode' library. *Note Old C Mode:
+(prog-modes)old-c-mode.
-Fortran Mode
-============
+ The old AWK mode exists for similar reasons. It is available in the
+`awk-mode' library. *Note Old AWK Mode: (prog-modes)awk-mode.
+
+ Note that the prog-modes package will never automatically invoke
+these older modes for a user. However installing the `cc-mode' package
+_will_ make CC Mode's versions available automatically. As a result a
+user who wants to use these older modes must explicitly load the old
+libraries to use them.
+

+
+21.12.2 Customizing Indentation in CC Mode
+------------------------------------------
+
+A very brief introduction is included here on customizing CC Mode. CC
+Mode has many features, including useful minor modes, that are
+completely documented in its own manual.
+
+ CC Mode implements several different "styles" for C code (and the
+other languages supported by CC Mode). If you need to change the
+indentation style for CC Mode it is recommended that you first see if an
+existing style meets your requirements. The style chosen will affect the
+placement of language elements like braces, function declarations and
+comments. You can choose a style interactively by typing `C-c .' and
+pressing the space bar at the prompt to get a list of supported styles.
+`C-c .' runs the function `c-set-style' which applies to all CC Mode
+language modes though its name might suggest otherwise. A few of the
+the supported styles are listed below.
+
+ * "gnu" -- The recommeded style from the Free Software Foundation for
+ GNU software.
+
+ * "k&r" -- The classic style from Kernighan and Ritchie.
+
+ * "linux" -- The style recommended for code in the Linux kernel.
+
+ * "bsd" -- The style recommended for software developed in BSD.
+
+ * "java -- The "traditional" Java style.
+
+ The default style in XEmacs is "gnu" except for Java mode where it
+is the "java" style (this is governed by the variable
+`c-default-style').
+
+ The styles included in CC Mode all use a buffer local variable called
+`c-basic-offset' as the basic indentation level (this buffer local
+variable is used in all CC Mode language modes though its name might
+suggest otherwise). All indentation is, by default, expressed in
+multiples of `c-basic-offset'.
+
+ Each style defines a default value for `c-basic-offset', for the
+"gnu" style sets it to 2. A very common customization scenario is where
+a user wants to use an existing style but with a different basic offset
+value. An easy way to do this is to set `c-basic-offset' in the
+language mode hook after selecting the chosen style.
+
+ For example, a user might want to follow a local coding convention of
+using the "k&r" style for C code with indentation in two columns
+multiples (instead of the five column default provided by the CC Mode
+"k&r" style). This can be achieved with the following code in the
+initialization file (*note Init File::)
+
+ (defun my-c-mode-hook ()
+ (c-set-style "k&r")
+ (setq c-basic-offset 2))
+ (add-hook 'c-mode-hook 'my-c-mode-hook)
+
+ Most customizations for indentation in various CC modes can be
+accomplished by choosing a style and then choosing value for
+`c-basic-offset' that meets the local coding convention. CC Mode has a
+very customizable indentation engine and a furthur discussion is really
+beyond the scope of this manual. *Note Indentation Engine:

-
-Evaluating Emacs-Lisp Expressions
-=================================
-
-Lisp programs intended to be run in Emacs should be edited in
-Emacs-Lisp mode; this will happen automatically for file names ending in
-`.el'. By contrast, Lisp mode itself should be used for editing Lisp
-programs intended for other Lisp systems. Emacs-Lisp mode can be
-selected with the command `M-x emacs-lisp-mode'.
-
- For testing of Lisp programs to run in Emacs, it is useful to be able
-to evaluate part of the program as it is found in the Emacs buffer. For
-example, if you change the text of a Lisp function definition and then
-evaluate the definition, Emacs installs the change for future calls to
-the function. Evaluation of Lisp expressions is also useful in any
-kind of editing task for invoking non-interactive functions (functions
-that are not commands).
-
-`M-:'
- Read a Lisp expression in the minibuffer, evaluate it, and print
- the value in the minibuffer (`eval-expression').
-
-`C-x C-e'
- Evaluate the Lisp expression before point, and print the value in
- the minibuffer (`eval-last-sexp').
-
-`C-M-x'
- Evaluate the defun containing point or after point, and print the
- value in the minibuffer (`eval-defun').
-
-`M-x eval-region'
- Evaluate all the Lisp expressions in the region.
-
-`M-x eval-current-buffer'
- Evaluate all the Lisp expressions in the buffer.
-
- `M-:' (`eval-expression') is the most basic command for evaluating a
-Lisp expression interactively. It reads the expression using the
-minibuffer, so you can execute any expression on a buffer regardless of
-what the buffer contains. When evaluation is complete, the current
-buffer is once again the buffer that was current when `M-:' was typed.
-
- In Emacs-Lisp mode, the key `C-M-x' is bound to the function
-`eval-defun', which parses the defun containing point or following point
-as a Lisp expression and evaluates it. The value is printed in the echo
-area. This command is convenient for installing in the Lisp environment
-changes that you have just made in the text of a function definition.
-
- The command `C-x C-e' (`eval-last-sexp') performs a similar job but
-is available in all major modes, not just Emacs-Lisp mode. It finds
-the sexp before point, reads it as a Lisp expression, evaluates it, and
-prints the value in the echo area. It is sometimes useful to type in an
-expression and then, with point still after it, type `C-x C-e'.
-
- If `C-M-x' or `C-x C-e' are given a numeric argument, they print the
-value by inserting it into the current buffer at point, rather than in
-the echo area. The argument value does not matter.
-
- The most general command for evaluating Lisp expressions from a
-buffer is `eval-region'. `M-x eval-region' parses the text of the
-region as one or more Lisp expressions, evaluating them one by one.
-`M-x eval-current-buffer' is similar, but it evaluates the entire
-buffer. This is a reasonable way to install the contents of a file of
-Lisp code that you are just ready to test. After finding and fixing a
-bug, use `C-M-x' on each function that you change, to keep the Lisp
-world in step with the source file.

-File: xemacs.info, Node: Lisp Debug, Next: Lisp Interaction, Prev: Lisp Eval, Up: Running
-
-The Emacs-Lisp Debugger
-=======================
-
-XEmacs contains a debugger for Lisp programs executing inside it. This
-debugger is normally not used; many commands frequently get Lisp errors
-when invoked in inappropriate contexts (such as `C-f' at the end of the
-buffer) and it would be unpleasant to enter a special debugging mode in
-this case. When you want to make Lisp errors invoke the debugger, you
-must set the variable `debug-on-error' to non-`nil'. Quitting with
-`C-g' is not considered an error, and `debug-on-error' has no effect on
-the handling of `C-g'. However, if you set `debug-on-quit' to be
-non-`nil', `C-g' will invoke the debugger. This can be useful for
-debugging an infinite loop; type `C-g' once the loop has had time to
-reach its steady state. `debug-on-quit' has no effect on errors.
-
- You can make Emacs enter the debugger when a specified function is
-called or at a particular place in Lisp code. Use `M-x debug-on-entry'
-with argument FUN-NAME to have Emacs enter the debugger as soon as
-FUN-NAME is called. Use `M-x cancel-debug-on-entry' to make the
-function stop entering the debugger when called. (Redefining the
-function also does this.) To enter the debugger from some other place
-in Lisp code, you must insert the expression `(debug)' there and
-install the changed code with `C-M-x'. *Note Lisp Eval::.
-
- When the debugger is entered, it displays the previously selected
-buffer in one window and a buffer named `*Backtrace*' in another
-window. The backtrace buffer contains one line for each level of Lisp
-function execution currently going on. At the beginning of the buffer
-is a message describing the reason that the debugger was invoked, for
-example, an error message if it was invoked due to an error.
-
- The backtrace buffer is read-only and is in Backtrace mode, a special
-major mode in which letters are defined as debugger commands. The
-usual Emacs editing commands are available; you can switch windows to
-examine the buffer that was being edited at the time of the error, and
-you can switch buffers, visit files, and perform any other editing
-operations. However, the debugger is a recursive editing level (*note
-Recursive Edit::); it is a good idea to return to the backtrace buffer
-and explicitly exit the debugger when you don't want to use it any
-more. Exiting the debugger kills the backtrace buffer.
-
- The contents of the backtrace buffer show you the functions that are
-executing and the arguments that were given to them. It also allows you
-to specify a stack frame by moving point to the line describing that
-frame. The frame whose line point is on is considered the "current
-frame". Some of the debugger commands operate on the current frame.
-Debugger commands are mainly used for stepping through code one
-expression at a time. Here is a list of them:
-
-`c'
- Exit the debugger and continue execution. In most cases,
- execution of the program continues as if the debugger had never
- been entered (aside from the effect of any variables or data
- structures you may have changed while inside the debugger). This
- includes entry to the debugger due to function entry or exit,
- explicit invocation, and quitting or certain errors. Most errors
- cannot be continued; trying to continue an error usually causes
- the same error to occur again.
-
-`d'
- Continue execution, but enter the debugger the next time a Lisp
- function is called. This allows you to step through the
- subexpressions of an expression, and see what the subexpressions
- do and what values they compute.

+22.4 Evaluating Emacs-Lisp Expressions
+======================================
+
+Lisp programs intended to be run in Emacs should be edited in
+Emacs-Lisp mode; this will happen automatically for file names ending in
+`.el'. By contrast, Lisp mode itself should be used for editing Lisp
+programs intended for other Lisp systems. Emacs-Lisp mode can be
+selected with the command `M-x emacs-lisp-mode'.
+
+ For testing of Lisp programs to run in Emacs, it is useful to be able
+to evaluate part of the program as it is found in the Emacs buffer. For
+example, if you change the text of a Lisp function definition and then
+evaluate the definition, Emacs installs the change for future calls to
+the function. Evaluation of Lisp expressions is also useful in any
+kind of editing task for invoking non-interactive functions (functions
+that are not commands).
+
+`M-:'
+ Read a Lisp expression in the minibuffer, evaluate it, and print
+ the value in the minibuffer (`eval-expression').
+
+`C-x C-e'
+ Evaluate the Lisp expression before point, and print the value in
+ the minibuffer (`eval-last-sexp').
+
+`C-M-x'
+ Evaluate the defun containing point or after point, and print the
+ value in the minibuffer (`eval-defun').
+
+`M-x eval-region'
+ Evaluate all the Lisp expressions in the region.
+
+`M-x eval-current-buffer'
+ Evaluate all the Lisp expressions in the buffer.
+
+ `M-:' (`eval-expression') is the most basic command for evaluating a
+Lisp expression interactively. It reads the expression using the
+minibuffer, so you can execute any expression on a buffer regardless of
+what the buffer contains. When evaluation is complete, the current
+buffer is once again the buffer that was current when `M-:' was typed.
+
+ In Emacs-Lisp mode, the key `C-M-x' is bound to the function
+`eval-defun', which parses the defun containing point or following point
+as a Lisp expression and evaluates it. The value is printed in the echo
+area. This command is convenient for installing in the Lisp environment
+changes that you have just made in the text of a function definition.
+
+ The command `C-x C-e' (`eval-last-sexp') performs a similar job but
+is available in all major modes, not just Emacs-Lisp mode. It finds
+the sexp before point, reads it as a Lisp expression, evaluates it, and
+prints the value in the echo area. It is sometimes useful to type in an
+expression and then, with point still after it, type `C-x C-e'.
+
+ If `C-M-x' or `C-x C-e' are given a numeric argument, they print the
+value by inserting it into the current buffer at point, rather than in
+the echo area. The argument value does not matter.
+
+ The most general command for evaluating Lisp expressions from a
+buffer is `eval-region'. `M-x eval-region' parses the text of the
+region as one or more Lisp expressions, evaluating them one by one.
+`M-x eval-current-buffer' is similar, but it evaluates the entire
+buffer. This is a reasonable way to install the contents of a file of
+Lisp code that you are just ready to test. After finding and fixing a
+bug, use `C-M-x' on each function that you change, to keep the Lisp
+world in step with the source file.

+
+22.5 The Emacs-Lisp Debugger
+============================
+
+XEmacs contains a debugger for Lisp programs executing inside it. This
+debugger is normally not used; many commands frequently get Lisp errors
+when invoked in inappropriate contexts (such as `C-f' at the end of the
+buffer) and it would be unpleasant to enter a special debugging mode in
+this case. When you want to make Lisp errors invoke the debugger, you
+must set the variable `debug-on-error' to non-`nil'. Quitting with
+`C-g' is not considered an error, and `debug-on-error' has no effect on
+the handling of `C-g'. However, if you set `debug-on-quit' to be
+non-`nil', `C-g' will invoke the debugger. This can be useful for
+debugging an infinite loop; type `C-g' once the loop has had time to
+reach its steady state. `debug-on-quit' has no effect on errors.
+
+ You can make Emacs enter the debugger when a specified function is
+called or at a particular place in Lisp code. Use `M-x debug-on-entry'
+with argument FUN-NAME to have Emacs enter the debugger as soon as
+FUN-NAME is called. Use `M-x cancel-debug-on-entry' to make the
+function stop entering the debugger when called. (Redefining the
+function also does this.) To enter the debugger from some other place
+in Lisp code, you must insert the expression `(debug)' there and
+install the changed code with `C-M-x'. *Note Lisp Eval::.
+
+ When the debugger is entered, it displays the previously selected
+buffer in one window and a buffer named `*Backtrace*' in another
+window. The backtrace buffer contains one line for each level of Lisp
+function execution currently going on. At the beginning of the buffer
+is a message describing the reason that the debugger was invoked, for
+example, an error message if it was invoked due to an error.
+
+ The backtrace buffer is read-only and is in Backtrace mode, a special
+major mode in which letters are defined as debugger commands. The
+usual Emacs editing commands are available; you can switch windows to
+examine the buffer that was being edited at the time of the error, and
+you can switch buffers, visit files, and perform any other editing
+operations. However, the debugger is a recursive editing level (*note
+Recursive Edit::); it is a good idea to return to the backtrace buffer
+and explicitly exit the debugger when you don't want to use it any
+more. Exiting the debugger kills the backtrace buffer.
+
+ The contents of the backtrace buffer show you the functions that are
+executing and the arguments that were given to them. It also allows you
+to specify a stack frame by moving point to the line describing that
+frame. The frame whose line point is on is considered the "current
+frame". Some of the debugger commands operate on the current frame.
+Debugger commands are mainly used for stepping through code one
+expression at a time. Here is a list of them:
+
+`c'
+ Exit the debugger and continue execution. In most cases,
+ execution of the program continues as if the debugger had never
+ been entered (aside from the effect of any variables or data
+ structures you may have changed while inside the debugger). This
+ includes entry to the debugger due to function entry or exit,
+ explicit invocation, and quitting or certain errors. Most errors
+ cannot be continued; trying to continue an error usually causes
+ the same error to occur again.
+
+`d'
+ Continue execution, but enter the debugger the next time a Lisp
+ function is called. This allows you to step through the
+ subexpressions of an expression, and see what the subexpressions
+ do and what values they compute.
+
+ When you enter the debugger this way, Emacs flags the stack frame
+ for the function call from which you entered. The same function
+ is then called when you exit the frame. To cancel this flag, use
+ `u'.
+
+`b'
+ Set up to enter the debugger when the current frame is exited.
+ Frames that invoke the debugger on exit are flagged with stars.
+
+`u'
+ Don't enter the debugger when the current frame is exited. This
+ cancels a `b' command on a frame.
+
+`e'
+ Read a Lisp expression in the minibuffer, evaluate it, and print
+ the value in the echo area. This is equivalent to the command
+ `M-:'.
+
+`q'
+ Terminate the program being debugged; return to top-level Emacs
+ command execution.
+
+ If the debugger was entered due to a `C-g' but you really want to
+ quit, not to debug, use the `q' command.
+
+`r'
+ Return a value from the debugger. The value is computed by
+ reading an expression with the minibuffer and evaluating it.
+
+ The value returned by the debugger makes a difference when the
+ debugger was invoked due to exit from a Lisp call frame (as
+ requested with `b'); then the value specified in the `r' command
+ is used as the value of that frame.
+
+ The debugger's return value also matters with many errors. For
+ example, `wrong-type-argument' errors will use the debugger's
+ return value instead of the invalid argument; `no-catch' errors
+ will use the debugger value as a throw tag instead of the tag that
+ was not found. If an error was signaled by calling the Lisp
+ function `signal', the debugger's return value is returned as the
+ value of `signal'.

-Reporting Bugs
-==============
-
-Sometimes you will encounter a bug in Emacs. Although we cannot promise
-we can or will fix the bug, and we might not even agree that it is a
-bug, we want to hear about bugs you encounter in case we do want to fix
-them.
-
- To make it possible for us to fix a bug, you must report it. In
-order to do so effectively, you must know when and how to do it.
-
-When Is There a Bug
--------------------
-
-If Emacs executes an illegal instruction, or dies with an operating
-system error message that indicates a problem in the program (as
-opposed to something like "disk full"), then it is certainly a bug.
-
- If Emacs updates the display in a way that does not correspond to
-what is in the buffer, then it is certainly a bug. If a command seems
-to do the wrong thing but the problem corrects itself if you type
-`C-l', it is a case of incorrect display updating.
-
- Taking forever to complete a command can be a bug, but you must make
-certain that it was really Emacs's fault. Some commands simply take a
-long time. Type `C-g' and then `C-h l' to see whether the input Emacs
-received was what you intended to type; if the input was such that you
-KNOW it should have been processed quickly, report a bug. If you don't
-know whether the command should take a long time, find out by looking
-in the manual or by asking for assistance.
-
- If a command you are familiar with causes an Emacs error message in a
-case where its usual definition ought to be reasonable, it is probably a
-bug.
-
- If a command does the wrong thing, that is a bug. But be sure you
-know for certain what it ought to have done. If you aren't familiar
-with the command, or don't know for certain how the command is supposed
-to work, then it might actually be working right. Rather than jumping
-to conclusions, show the problem to someone who knows for certain.
-
- Finally, a command's intended definition may not be best for editing
-with. This is a very important sort of problem, but it is also a
-matter of judgment. Also, it is easy to come to such a conclusion out
-of ignorance of some of the existing features. It is probably best not
-to complain about such a problem until you have checked the
-documentation in the usual ways, feel confident that you understand it,
-and know for certain that what you want is not available. If you are
-not sure what the command is supposed to do after a careful reading of
-the manual, check the index and glossary for any terms that may be
-unclear. If you still do not understand, this indicates a bug in the
-manual. The manual's job is to make everything clear. It is just as
-important to report documentation bugs as program bugs.
-
- If the online documentation string of a function or variable
-disagrees with the manual, one of them must be wrong, so report the bug.
-
-How to Report a Bug
--------------------
-
-When you decide that there is a bug, it is important to report it and to
-report it in a way which is useful. What is most useful is an exact
-description of what commands you type, starting with the shell command
-to run Emacs, until the problem happens. Always include the version
-number of Emacs that you are using; type `M-x emacs-version' to print
-this.
-
- The most important principle in reporting a bug is to report FACTS,
-not hypotheses or categorizations. It is always easier to report the
-facts, but people seem to prefer to strain to posit explanations and
-report them instead. If the explanations are based on guesses about
-how Emacs is implemented, they will be useless; we will have to try to
-figure out what the facts must have been to lead to such speculations.
-Sometimes this is impossible. But in any case, it is unnecessary work
-for us.
-
- For example, suppose that you type `C-x C-f /glorp/baz.ugh <RET>',
-visiting a file which (you know) happens to be rather large, and Emacs
-prints out `I feel pretty today'. The best way to report the bug is
-with a sentence like the preceding one, because it gives all the facts
-and nothing but the facts.
-
- Do not assume that the problem is due to the size of the file and
-say, "When I visit a large file, Emacs prints out `I feel pretty
-today'." This is what we mean by "guessing explanations". The problem
-is just as likely to be due to the fact that there is a `z' in the file
-name. If this is so, then when we got your report, we would try out
-the problem with some "large file", probably with no `z' in its name,
-and not find anything wrong. There is no way in the world that we
-could guess that we should try visiting a file with a `z' in its name.
-
- Alternatively, the problem might be due to the fact that the file
-starts with exactly 25 spaces. For this reason, you should make sure
-that you inform us of the exact contents of any file that is needed to
-reproduce the bug. What if the problem only occurs when you have typed
-the `C-x a l' command previously? This is why we ask you to give the
-exact sequence of characters you typed since starting to use Emacs.
-
- You should not even say "visit a file" instead of `C-x C-f' unless
-you know that it makes no difference which visiting command is used.
-Similarly, rather than saying "if I have three characters on the line,"
-say "after I type `<RET> A B C <RET> C-p'," if that is the way you
-entered the text.
-
- If you are not in Fundamental mode when the problem occurs, you
-should say what mode you are in.
-
- If the manifestation of the bug is an Emacs error message, it is
-important to report not just the text of the error message but a
-backtrace showing how the Lisp program in Emacs arrived at the error.
-To make the backtrace, you must execute the Lisp expression `(setq
-debug-on-error t)' before the error happens (that is to say, you must
-execute that expression and then make the bug happen). This causes the
-Lisp debugger to run (*note Lisp Debug::). The debugger's backtrace
-can be copied as text into the bug report. This use of the debugger is
-possible only if you know how to make the bug happen again. Do note
-the error message the first time the bug happens, so if you can't make
-it happen again, you can report at least that.
-
- Check whether any programs you have loaded into the Lisp world,
-including your init file, set any variables that may affect the
-functioning of Emacs. *Note Init File::. Also, see whether the
-problem happens in a freshly started Emacs without loading your init
-file (start Emacs with the `-q' switch to prevent loading the init
-file). If the problem does NOT occur then, it is essential that we
-know the contents of any programs that you must load into the Lisp
-world in order to cause the problem to occur.
-
- If the problem does depend on an init file or other Lisp programs
-that are not part of the standard Emacs system, then you should make
-sure it is not a bug in those programs by complaining to their
-maintainers first. After they verify that they are using Emacs in a
-way that is supposed to work, they should report the bug.
-
- If you can tell us a way to cause the problem without visiting any
-files, please do so. This makes it much easier to debug. If you do
-need files, make sure you arrange for us to see their exact contents.
-For example, it can often matter whether there are spaces at the ends
-of lines, or a newline after the last line in the buffer (nothing ought
-to care whether the last line is terminated, but tell that to the bugs).
-
- The easy way to record the input to Emacs precisely is to write a
-dribble file; execute the Lisp expression:
-
- (open-dribble-file "~/dribble")
-
-using `Meta-<ESC>' or from the `*scratch*' buffer just after starting
-Emacs. From then on, all Emacs input will be written in the specified
-dribble file until the Emacs process is killed.
-
- For possible display bugs, it is important to report the terminal
-type (the value of environment variable `TERM'), the complete termcap
-entry for the terminal from `/etc/termcap' (since that file is not
-identical on all machines), and the output that Emacs actually sent to
-the terminal. The way to collect this output is to execute the Lisp
-expression:
-
- (open-termscript "~/termscript")
-
-using `Meta-<ESC>' or from the `*scratch*' buffer just after starting
-Emacs. From then on, all output from Emacs to the terminal will be
-written in the specified termscript file as well, until the Emacs
-process is killed. If the problem happens when Emacs starts up, put
-this expression into your init file so that the termscript file will be
-open when Emacs displays the screen for the first time. *Note Init
-File::. Be warned: it is often difficult, and sometimes impossible, to
-fix a terminal-dependent bug without access to a terminal of the type
-that stimulates the bug.

+ ***** To update the menus and nodes *****
+ *****************************************
+
+First, the first argument to @node (the name itself) needs to be correct.
+Use a macro if necessary to update the @node names from the
+@unnumberedsubsec commands. Also note that the command we're about to
+run will not correctly fix up the part of the menu to the right of a ::.
+It will leave existing text in place but not change anything. If you
+make a lot of changes and want to update this semi-automatically, use
+M-x occur to pick out all @unnumberedsubsec lines then do some editing
+magic to coerce them into the right format and cut and paste as necessary:
+
+1. M-x occur @unnumberedsubsec
+2. <select a rectangle including all text before the Q#.#.#>
+3. C-x r t *<space>
+4. go to the top and use the following macro to get the indentation right.
+
+(setq last-kbd-macro (read-kbd-macro
+"C-s : RET : <right> M-x indent- to- column RET 14 RET <home> <down>"))
+
+5. Cut and paste the menus into the detailmenu at the top and
+ individual menus at the top of the appropriate chapters. (#### I
+ wonder, does texinfo-master-menu generate the detailmenu from the
+ individual menus or vice-versa or neither?)
+
+Then,
+
+6. C-u C-c C-u m (C-u M-x texinfo-master-menu) will update the menus
+ and nodes. However, it appears that even though it tries to
+ preserve the existing menu structure as much as possible, it
+ doesn't do a perfect job. It messes up in at least two ways: The
+ indentation in the part of the main menu above the detailmenu will
+ be screwed up, and the #.0 titles will be removed from both the
+ detailmenu and the individual chapter menus. In addition,
+ sometimes random things get screwed up in individual parts of the
+ menus. Therefore:
+
+ 1. Use the Lisp line below to get the spacing correct for the Q#.#.#
+ menu entries.
+
+(set (make-local-variable 'texinfo-column-for-description) 14)
+
+ 2. Copy the whole detailmenu beforehand.
+ 3. Run C-u C-c C-u m to fix up the nodes.
+ 4. Run `fix-main-menu' and `fix-omitted-menu-lines'.
+ 5. Check the new detailmenu carefully to see if anything is screwed up
+ compared to the old detailmenu you copied.
+ 6. If so, paste back the appropriate sections and fix up the corresponding
+ part of the chapter-specific menu.
+
+(defun fix-main-menu ()
+ (interactive)
+ (save-restriction
+ (let (p q)
+ (goto-char (point-min))
+ (re-search-forward "^@menu")
+ (setq p (match-beginning 0))
+ (re-search-forward "^$")
+ (setq q (match-end 0))
+ (narrow-to-region p q)
+ (goto-char p)
+ (while (search-forward ":: " nil t)
+ (indent-to-column 26)))))
+
+(defun fix-omitted-menu-lines ()
+ (interactive)
+ (save-excursion
+ (loop for x from 1 to 10 do
+ (goto-char (point-min))
+ (re-search-forward (format "@unnumberedsec \\(%d.0: .*\\)" x))
+ (let ((line (match-string 1)))
+ (re-search-backward "^@menu")
+ (forward-line 1)
+ (unless (looking-at "[0-9]+.0:")
+ (insert line)
+ (insert "\n"))
+ (goto-char (point-min))
+ (re-search-forward "^@menu")
+ (search-forward (format "Q%d.0.1:" x))
+ (forward-line -1)
+ (unless (looking-at "[0-9]+.0:")
+ (insert "\n")
+ (insert line))))))

+When you've rearranged and renumbered a bunch of nodes, you can get
+the numbers agreeing again. The macro below assumes that the
+unnumberedsubsec number is correct, and fixes up the node to agree.
+Only the first part of the node is fixed and the other parts may still
+be wrong; but they will be fixed as part of
+@code{texinfo-master-menu}.

XEmacs is a powerful, highly customizable open source text editor and
-application development system, with full GUI support. It is protected
-under the GNU Public License and related to other versions of Emacs, in
-particular GNU Emacs. Its emphasis is on modern graphical user
-interface support and an open software development model, similar to
-Linux. XEmacs has an active development community numbering in the
-hundreds (and thousands of active beta testers on top of this), and runs
-on all versions of MS Windows, on Linux, and on nearly every other
-version of Unix in existence. Support for XEmacs has been supplied by
-Sun Microsystems, University of Illinois, Lucid, ETL/Electrotechnical
-Laboratory, Amdahl Corporation, BeOpen, and others, as well as the
-unpaid time of a great number of individual developers.

-@itemize @bullet
-@item
-It looks nicer.
+XEmacs is the result of the time and effort of many people, and the
+active developers have changed over time. There are two major
+components of the XEmacs effort -- writing the code itself and providing
+all the support work (testing the code, releasing beta and final
+versions, handling patches, reading bug reports, maintaining the web
+site, managing the mailing lists, etc. etc.). Neither component would
+work without the other.
-@item
-The XEmacs maintainers are generally more receptive to suggestions than
-the GNU Emacs maintainers.
+@subheading CODING
-@item
-Many more bundled packages than GNU Emacs.
+The primary code contributor over the years has been Ben Wing (active
+since late 1992). Between 1991 and 1995, large amounts of coding was
+contributed by Jamie Zawinski and Chuck Thompson. Many other people
+have authored major subsystems or otherwise contributed large amounts of
+code, including Andy Piper, Hrvoje Niksic, Jerry James, Jonathan Harris,
+Kyle Jones, Martin Buchholz, Michael Sperber, Olivier Galibert, Richard
+Mlynarik, Stig, William Perry and plenty of others.

-Mule supports a wide variety of input methods. There are three basic
-classes: Lisp implementations, generic platform support, and library
-interfaces.
+@unnumberedsec 1.2: Versions for Different Operating Systems
-@emph{Lisp implementations} include Quail, which provides table-driven input
-methods for almost all the character sets that Mule supports (including
-all of the ISO 8859 family, the Indic languages, Thai, and so on), and
-SKK, for Japanese. (SKK also supports an interface to an external
-"dictionary server" process.) Quail supports both typical "dead-key"
-methods (eg, in the "latin-1-prefix" method, @kbd{" a} produces ä, LATIN
-SMALL LETTER A WITH DIAERESIS), and the complex dictionary-based phonetic
-methods used for Asian ideographic languages like Chinese.
+@node Q1.2.1, Q1.2.2, Q1.1.4, Introduction
+@unnumberedsubsec Q1.2.1: Do I need X11 to run XEmacs?
-Lisp implementations can be less powerful (but they are not perceptibly
-inefficient), and of course are not portable to non-Emacs applications.
-The incompatibility can be very annoying. On the other hand, they
-require no special platform support or external libraries, so if you can
-display the characters, Mule can input them for you and you can edit,
-anywhere.
+No. The name @dfn{XEmacs} is unfortunate in the sense that it is
+@strong{not} an X Window System-only version of Emacs. XEmacs has
+full color support on a color-capable character terminal.
-@emph{Generic platform support} is currently limited to the X Input
-Method (XIM) framework, although support for MSIME (for MS Windows) is
-planned, and IIIMF (Sun's Internet-Intranet Input Method Framework)
-support is extremely desirable. XIM is enabled at build time by use of
-the @samp{--with-xim} flag to @code{configure}. For use of XIM, see
-your platform documentation. However, normally the input method you use
-is specified via the @samp{LANG} and @samp{XMODIFIERS} environment
-variables.
+@node Q1.2.2, Q1.2.3, Q1.2.1, Introduction
+@unnumberedsubsec Q1.2.2: What versions of Unix does XEmacs run on?
-Of course, input skills are portable across most applications. However,
-especially in modern GUI systems the habit of using bucky bits has
-fallen into sad disuse, and many XIM systems are poorly configured for
-use with Emacs. For example, the kinput2 input manager (a separate
-process providing an interface between Japanese dictionary servers such
-as Canna and Wnn, and the application) tends to gobble up keystrokes
-generating Meta characters. This means that to edit while using an XIM
-input method, you must toggle the input method off every time you want
-to use @kbd{M-f}. Your mileage may vary.
+XEmacs is regularly tested on Linux, Solaris, SunOS, HP/UX, FreeBSD,
+OpenBSD, BSD/OS aka BSDI, Tru64 aka DEC/OSF, SCO5, and probably
+others. It should work on all versions of Unix created in the last 10
+years or so, perhaps with a bit of work on more obscure platforms to
+correct bit-rot. It uses a sophisticated configuration system to
+auto-detect zillions of features that are implemented differently in
+different versions of Unix, so it will probably work on your vendor's
+version, possibly with a bit of tweaking, even if we've never heard of
+it.
-@emph{Library interfaces} are most common for Japanese, although Wnn
-supports Chinese (traditional and simplified) and Korean. There are
-Chinese and Korean input servers available, but we do not know of any
-patches for XEmacs to use them directly. You can use them via
-IM-enabled terminals, by manipulating the terminal coding systems. We
-describe only the Japanese-oriented systems here. The advantage of
-these systems is that they are very powerful, and on platforms where
-they are available there is typically a wide range of applications that
-support them. Thus your input skills are portable across applications.
+For problems with particular machines and versions of Unix, see the
+@file{PROBLEMS} file.
-Mule provides built-in interfaces to the following input methods: Wnn4,
-Wnn6, Canna, and SJ3. These can be configured at build time. There are
-patches available (no URL, sorry) to support the SKK server, as well.
-Wnn and SJ3 use the @code{egg} user interface. The interface for Canna
-is specialized to Canna.
+Much effort has gone into making XEmacs work on as many different
+machines, configurations, and compilers as possible.
-Wnn supports Japanese, Chinese and Korean. It is made by OMRON and Kyôto
-University. It is a powerful and complex system. Wnn4 is free and Wnn6
-is not. Wnn uses grammatical hints and probability of word association,
-so in principle Wnn can be cleverer than other methods.
+Much effort has gone into making XEmacs 64-bit clean.
-Canna, made by NEC, supports only Japanese. It is a simple and powerful
-system. Canna uses only grammar, but its grammar and dictionary are
-quite sophisticated. So for standard modern Japanese, Canna seems
-cleverer than Wnn4. In addition, the UNIX version of Canna is free (now
-there is a Microsoft Windows version).
+Much effort has gone into removing system-specific code, and replacing
+such code with autodetection at configure time.
-SJ3, by Sony, supports only Japanese.
+The XEmacs core should build "out of the box" on most Unix-like systems.

+64-bit version of the compiler.
-These input methods are modal. They have a raw (alphabet) mode, a

-mode-less input methods for Egg and Canna. @samp{boiled-egg} is a
-mode-less input method running on Egg. For Canna, @samp{canna.el} has a

+
+Yes.
+
+XEmacs 21.5 (perhaps 21.4 also?) works on MacOS X, although it certainly
+will not feel very much like a Mac application as it has no Mac-specific
+code in it.
+
+There is also a port of XEmacs 19.14 that works on all recent versions
+of MacOS, from 8.1 through MacOS X, by @email{pjarvis@@ispchannel.com,
+Pitts Jarvis} (recently deceased). It runs in an equivalent of TTY

+@unnumberedsubsec Q1.3.2: Where do I put my @file{init.el} file?
+
+@file{init.el} is the name of the init file starting with 21.4, and is
+located in the subdirectory @file{.xemacs/} of your home directory. In
+prior versions, the init file is called @file{.emacs} and is located in
+your home directory.
+
+Your home directory under Windows is determined by the @samp{HOME}
+environment variable. If this is not set, it defaults to @samp{C:\}.

+@item User-Visible Editing Features
+XEmacs in general tries hard to conform to exist user-interface
+standards, and to work "out-of-the-box" without the need for obscure
+customization changes. GNU Emacs, particularly version 21, has gotten
+better about this (in many cases by copying the XEmacs behavior!), but
+still has some weirdnesses. For example, the standard method of
+selecting text using the Shift key works out-of-the-box in XEmacs.
+
+XEmacs has a built-in toolbar. Four toolbars can actually be configured
+simultaneously: top, bottom, left, and right toolbars.
+
+XEmacs has vertical and horizontal scrollbars. Unlike in GNU Emacs 19
+(which provides a primitive form of vertical scrollbar), these are true
+toolkit scrollbars. A look-alike Motif scrollbar is provided for those
+who don't have Motif. (Even for those who do, the look-alike may be
+preferable as it is faster.)
+
+XEmacs has buffer tabs along the top of the frame (although the
+position can be changed) that make it very easy to switch buffers.
+
+The menubar under XEmacs is better-designed, with more thought put into
+it.
+
+XEmacs can ask questions using popup dialog boxes. Any command executed
+from a menu will ask yes/no questions with dialog boxes, while commands
+executed via the keyboard will use the minibuffer.
+
+XEmacs under MS Windows provides uses the standard file-dialog box for
+opening and saving files. Standard menu-accelerator behavior can easily
+be enabled using the Options menu, and integrates well into the existing
+keymap.
+
+XEmacs has (still experimental) support for widgets of various sorts --
+buttons, text boxes, sliders, progress bars, etc. A progress bar is
+used in font lock to show the progress.
+
+Experimental support for drag-and-drop protocols is provided from
+XEmacs 21.
+
+@item General Platform Support
+If you're running on a machine with audio hardware, you can specify
+sound files for XEmacs to play instead of the default X beep. See the
+documentation of the function load-sound-file and the variable
+sound-alist. XEmacs also supports the network sound protocols NAS and
+EsounD.
+
+XEmacs 21 supports database protocols with LISP bindings, currently
+including Berkeley DB, LDAP, and PostgreSQL (21.2 only).
+
+XEmacs 20 and 21 support the Canna, Wnn, and SJ3 Japanese input method
+servers directly, as well as through the X Input Method (XIM)
+protocol. GNU Emacs 20 supports only the XIM protocol. Both Emacsen
+support the Quail family of input methods (implemented in LISP) for many
+languages.
+
+XEmacs provides support for ToolTalk on systems that have
+it.
+
+@item Packaged LISP Libraries
+Many more packages are provided standard with XEmacs than with GNU Emacs
+19 or 20.
+
+XEmacs 21 supports an integrated package management system which uses
+EFS to download, then automatically install prebuilt LISP
+libraries. This allows XEmacs users much more straightforward access to
+the "latest and greatest" version of any given library.
+
+We are working on a standard method for enabling, disabling and
+otherwise controlling packages, which should make them very easy to use.
+
+@item LISP Programming
+From XEmacs 20 on, characters are a separate type. Characters can be
+converted to integers (and many integers can be converted to
+characters), but characters are not integers. GNU Emacs 19, XEmacs 19,
+Mule 2.3 (an extensive patch to GNU Emacs 18.55 and 19.x), and GNU Emacs
+20 (incorporating Mule 3 and later Mule 4) represent them as integers.
+
+From XEmacs 20 on, the buffer is treated as an array of characters, and
+the representation of buffer text is not exposed to LISP. The GNU Emacs
+20 functions like buffer-as-multibyte are not supported.
+
+In XEmacs, events are first-class objects. GNU Emacs 19 represents them
+as integers, which obscures the differences between a key gesture and
+the ancient ASCII code used to represent a particular overlapping subset
+of them.
+
+In XEmacs, keymaps are first-class opaque objects. GNU Emacs 19
+represents them as complicated combinations of association lists and
+vectors. If you use the advertised functional interface to manipulation
+of keymaps, the same code will work in XEmacs, GNU Emacs 18, and GNU
+Emacs 19; if your code depends on the underlying implementation of
+keymaps, it will not.
+
+XEmacs uses "extents" to represent all non-textual aspects of buffers;
+GNU Emacs 19 uses two distinct objects, "text properties" and
+"overlays", which divide up the functionality between them. Extents are
+a superset of the union of the functionality of the two GNU Emacs data
+types. The full GNU Emacs 19 interface to text properties and overlays
+is supported in XEmacs (with extents being the underlying
+representation).
+
+Extents can be made to be copied into strings, and then restored, by
+kill and yank. Thus, one can specify this behavior on either "extents"
+or "text properties", whereas in GNU Emacs 19 text properties always
+have this behavior and overlays never do.
+
+@item Window System Programming Interface
+XEmacs uses the MIT "Xt" toolkit instead of raw Xlib calls, which makes
+it be a more well-behaved X citizen (and also improves portability). A
+result of this is that it is possible to include other Xt "Widgets" in
+the XEmacs window. Also, XEmacs understands the standard Xt command-line
+arguments.
+
+XEmacs supports Motif applications, generic Xt (e.g. Athena)
+applications, and raw Xlib applications. An XEmacs variant which
+supports GTK+ is available (integration as an option in the XEmacs
+mainline is planned for XEmacs 22), although code to take advantage of
+the support is as yet scarce.
+
+An XEmacs frame can be placed within an "external client widget" managed
+by another application. This allows an application to use an XEmacs
+frame as its text pane rather than the standard Text widget that is
+provided with Motif or Athena.
+
+@item Community Participation
+Joining the XEmacs development team is simple. Mail to
+@email{xemacs-beta@@xemacs.org, XEmacs Developers}, and you're in! (If
+you want to be, of course. You're also welcome to just post
+development-related questions and bug reports.) The GNU Emacs
+development team and internal mailing lists are still by invitation
+only.
+
+The "bleeding edge" of mainline XEmacs development is available by
+anonymous CVS as are some subsidiary branches (check out the xemacs-gtk
+module for the latest in GUI features!)
+
+Development and maintenance of Lisp libraries is separated from the core
+editor development at a fairly low level. This provides better
+modularization and a better division of responsibility between external
+library maintainers and the XEmacs core development team. Even for
+packages the size of Gnus, XEmacs users normally have access to a
+pre-built version within a few weeks of a major release, and minor
+updates often within days.
+
+CVS commit authority is broadly dispersed. Recognized maintainers of
+LISP libraries who are willing to maintain XEmacs packaged versions
+automatically qualify for CVS accounts for their packages.

+distributed XEmacs, and RMS's hostility is the farthest thing possible
+from an endorsement. In fact, the GNU Project distributes a number of
+non-GNU software projects on the FSF web site, but again XEmacs is not
+one of them.
+
+@node Q1.6.5, Q1.6.6, Q1.6.4, Introduction
+@unnumberedsubsec Q1.6.5: What is the correct way to refer to XEmacs and GNU Emacs?
+
+Unfortunately even the naming of these two applications has become
+politicized. Much of this stems from RMS, who has a history of
+politicizing similar issues. (Compare the controversy over "Lignux"
+and "GNU/Linux".) We would prefer that the terms "XEmacs" and "GNU
+Emacs" be used, which are neutral and acceptable to most people. RMS,
+however, is not willing to accept these terms. He insists that, if
+his product is called "GNU Emacs", then ours must be called "GNU
+XEmacs". (For our opinion of this term, @xref{Q1.6.4}.) On the other
+hand, if our product is to be called "XEmacs", as we prefer, then his
+product must simply be called "Emacs". The intent of this seems
+clear: RMS wants to make sure the names reflect his view that his
+version is the "real" Emacs and ours is merely a derivative,
+second-class product (@pxref{Q1.6.3}).
+
+The XEmacs developers hope that you will use the neutral terms
+"XEmacs" and "GNU Emacs" for these two specific products. "Emacs", on
+the other hand, is a generic term for a class of programmable text
+editors with a similar look-and-feel, and usually a Lisp-based
+extension language. These trace themselves back to early editors such
+as EINE, ZWEI, ZMACS and Multics Emacs. @xref{A History of Emacs,,,
+internals, XEmacs Internals Manual}.
+
+We also call upon RMS, in the spirit of furthering cooperation, to
+stop politicizing this issue and use the neutral terms "XEmacs" and
+"GNU Emacs". We have already acceded to RMS' wishes in this respect,
+and we expect him to do the same. (In the past, the XEmacs developers
+often used the terms "FSF Emacs" or "FSFmacs" or "RMSmacs" in
+reference to GNU Emacs; these terms were apparently modeled after RMS'
+own usage of "Gosmacs" and "Gosling Emacs" in reference to Unipress
+Emacs, produced by James Gosling. RMS, however, considers such terms
+to be insulting, so we refrain from using them as much as possible in
+preference to GNU Emacs.)
+
+@node Q1.6.6, Q1.7.1, Q1.6.5, Introduction
+@unnumberedsubsec Q1.6.6: Why haven't XEmacs and GNU Emacs merged?
-A typical error: FTP Error: USER request failed; 500 AUTH not understood.
+There are currently irreconcilable differences in the views about
+technical, programming, design, organizational and legal matters
+between Richard Stallman (RMS), the author and leader of the GNU Emacs
+project, and the XEmacs development team which provide little hope for
+a merge to take place in the short-term future. There have been
+repeated attempts at merging by all of the major XEmacs developers,
+starting from the early days of Lucid Emacs (in 1991), but they have
+all failed. RMS has very strong views about how GNU Emacs should be
+structured and how his project should be run, and during the repeated
+merge efforts has never demonstrated any realistic interest in
+sufficiently compromising or ceding control to allow a middle ground
+to be found. The basic problem seems to be the very different goals
+of RMS and the XEmacs project. The primary goals of the XEmacs
+project are technical and organizational -- we want to create the best
+editor possible, and to make it as easy as possible for people around
+the world to contribute. The primary goals of RMS, on the other hand,
+are political, and GNU Emacs, and any potential merge efforts with
+XEmacs, are strictly subservient to these goals. In fact, in many
+ways RMS sees GNU Emacs as the "poster child" of his aims, the one
+program in the GNU project that above all others must set an example
+to the world. (This has to do with the fact that GNU Emacs was the
+first program in the GNU project, and the only one that he is still
+personally involved with on a day-to-day basis.) Given his goals, his
+position is completely reasonable -- but unfortunately, makes any
+merge impossible.
+
+From the XEmacs perspective, the most intractable issues appear to be
+legal and organizational, specifically:
-Thanks to giacomo boffi @email{giacomo.boffi@@polimi.it} who recommends
-on comp.emacs.xemacs:
+@itemize @bullet
+@item
+RMS requires "legal papers" to be signed for all contributions of code
+to GNU Emacs over 10 lines or so, transferring the copyright and all
+legal rights to the code to the Free Software Foundation. XEmacs does
+not and has never required this, since it has the practical effect of
+discouraging individual and in particular corporate contributions --
+corporations will almost never sign away their legal rights to code
+since it makes it impossible to reuse the code in any product that
+whose license is not compatible with the GNU General Public License.
+Since RMS has shown no inclination to compromise on this issue, a
+merge would require that most of the existing XEmacs code would need
+to be thrown away and rewritten -- something the XEmacs developers are
+understandably reluctant to do.
+
+@item
+A repeated stumbling block in the merge talks has been the issue of
+organizational control over the resulting product. RMS has made it
+clear that he intends to have final say over design issues in a merged
+Emacs. Unfortunately, RMS and the XEmacs developers have repeatedly
+clashed over design decisions, and RMS' insistence on getting his way
+in such disagreements was the very reason for the split in the first
+place. This same issue has come up again and again in merge talks and
+we have never been able to come to a satisfactory resolution. To the
+extent that RMS is willing to compromise at all, it appears to be of a
+purely political rather than technical nature -- "If we support this
+feature of yours, we also get to support this other feature of mine."
+The XEmacs developers cannot see how such a process would lead to
+anything but a mess of incompatible things hodgepodged together.
+
+@item
+Because of the years of separate development, distinct and
+incompatible interfaces have developed and merging would be extremely
+difficult even with the above non-technical issues resolved. The
+problem has been exacerbated by the issue of legal papers -- because
+XEmacs code is not "kosher" from RMS' perspective, he discourages
+developers from even looking at it out of legal concerns. Although it
+is still possible to read the XEmacs documentation and run the
+program, the practical effect of this prohibition has been to strongly
+discourage code-sharing and cooperative development -- although a
+great deal of GNU Emacs code has been incorporated into XEmacs,
+practically none has gone the other direction.

-@unnumberedsubsec Q2.1.1: Help! XEmacs just crashed on me!
+A very broad collection of elisp packages.
-First of all, don't panic. Whenever XEmacs crashes, it tries extremely
-hard to auto-save all of your files before dying. (The main time that
-this will not happen is if the machine physically lost power or if you
-killed the XEmacs process using @code{kill -9}). The next time you try
-to edit those files, you will be informed that a more recent auto-save
-file exists. You can use @kbd{M-x recover-file} to retrieve the
-auto-saved version of the file.
+@table @asis
+@item Sun
+Support for Sparcworks.
-You can use the command @kbd{M-x recover-session} after a crash to pick

+@item ada
+Ada language support.
-Now, XEmacs is not perfect, and there may occasionally be times, or
-particular sequences of actions, that cause it to crash. If you can
-come up with a reproducible way of doing this (or even if you have a
-pretty good memory of exactly what you were doing at the time), the
-maintainers would be very interested in knowing about it. The best way
-to report a bug is using @kbd{M-x report-emacs-bug} (or by selecting
-@samp{Send Bug Report...} from the Help menu). If that won't work
-(e.g. you can't get XEmacs working at all), send ordinary mail to
-@email{crashes@@xemacs.org}. @emph{MAKE SURE} to include the output from
-the crash, especially including the Lisp backtrace, as well as the
-XEmacs configuration from @kbd{M-x describe-installation} (or
-equivalently, the file @file{Installation} in the top of the build
-tree). Please note that the @samp{crashes} address is exclusively for
-crash reports. The best way to report bugs in general is through the
-@kbd{M-x report-emacs-bug} interface just mentioned, or if necessary by
-emailing @email{xemacs-beta@@xemacs.org}. Note that the developers do
-@emph{not} usually follow @samp{comp.emacs.xemacs} on a regular basis;

-locate the core file (it's called @file{core}, and is usually sitting in
-the directory that you started XEmacs from, or your home directory if
-that other directory was not writable). Then, go to that directory and
-execute a command like:

+@item time
+Display time & date on the modeline.
-If XEmacs does crash on you, one of the most productive things you can
-do to help get the bug fixed is to poke around a bit with the debugger.
-Here are some hints:
+@item tm
+Emacs MIME support. Not needed for gnus >= 5.8.0.
-@itemize @bullet
-@item
-First of all, if the crash is at all reproducible, consider very
-strongly recompiling your XEmacs with debugging symbols and with no
-optimization (e.g. with GCC use the compiler flags @samp{-g -O0} --
-that's an "oh" followed by a zero), and with the configure options
-@samp{--debug=yes} and @samp{--error-checking=all}. This will make your
-XEmacs run somewhat slower, but you are a lot more likely to catch the
-problem earlier (closer to its source). It makes it a lot easier to
-determine what's going on with a debugger.
+@item tooltalk
+Support for building with Tooltalk.
-@item
-If it's not a true crash (@emph{i.e.}, XEmacs is hung, or a zombie
-process), or it's inconvenient to run XEmacs again because XEmacs is
-already running or is running in batch mode as part of a bunch of
-scripts, you may be able to attach to the existing process with your
-debugger. Most debuggers let you do this by substituting the process ID
-for the core file when you invoke the debugger from the command line, or
-by using the @code{attach} command or something similar.
+@item tpu
+DEC EDIT/TPU support.
-@item
-If you're able to run XEmacs under a debugger and reproduce the crash,
-here are some things you can do:
+@item tramp
+Remote shell-based file editing. This is similar to EFS or Ange-FTP,
+but works with rsh/ssh and rcp/scp.
-@item
-If XEmacs is hitting an assertion failure, put a breakpoint on
-@code{assert_failed()}.
+@item vc
+Version Control for Free systems.
-@item
-If XEmacs is hitting some weird Lisp error that's causing it to crash
-(e.g. during startup), put a breakpoint on @code{signal_1()}---this is
-declared static in eval.c.
+@item vc-cc
+Version Control for ClearCase (UnFree) systems.
-@item
-If XEmacs is outputting lots of X errors, put a breakpoint on
-@code{x_error_handler()}; that will tell you which call is causing them.
+@item vhdl
+Support for VHDL.
-@item
-Internally, you will probably see lots of variables that hold objects of
-type @code{Lisp_Object}. These are references to Lisp objects.
-Printing them out with the debugger probably won't be too
-useful---you'll likely just see a number. To decode them, do this:
+@item view-process
+A Unix process browsing tool.
-@example
-call dp (OBJECT)
-@end example
+@item viper
+VI emulation support.
-where @var{OBJECT} is whatever you want to decode (it can be a variable,
-a function call, etc.). This uses the Lisp printing routines to out a
-readable representation on the TTY from which the xemacs process was
-invoked.
+@item vm
+An Emacs mailer.
-@item
-If you want to get a Lisp backtrace showing the Lisp call
-stack, do this:
+@item w3
+A Web browser.
-@example
-call db ()
-@end example
+@item x-symbol
+Semi WYSIWYG for LaTeX, HTML, etc, using additional fonts.
-@item
-Using @code{dp} and @code{db} has two disadvantages - they can only be
-used with a running (including hung or zombie) xemacs process, and they
-do not display the internal C structure of a Lisp Object. Even if all
-you've got is a core dump, all is not lost.
+@item xemacs-base
+Fundamental XEmacs support, you almost certainly need this.
-If you're using GDB, there are some macros in the file
-@file{src/.gdbinit} in the XEmacs source distribution that should make
-it easier for you to decode Lisp objects. This file is automatically
-read by gdb if gdb is run in the directory where xemacs was built, and

-dynamic linking. (This happens especially under Linux.) Consider
-reconfiguring with @samp{--dynamic=no}. Also, sometimes (again under
-Linux), stack backtraces of core dumps will have the frame where the
-fatal signal occurred mangled; if you can obtain a stack trace while
-running the XEmacs process under a debugger, the stack trace should be
-clean.

+MULE: Quail. All non-English and non-Japanese language support.
-@enumerate a

-Your executable has been stripped. Bad news. Tell your sysadmin not to
-do this---it doesn't accomplish anything except to save a bit of disk
-space, and makes debugging much much harder.
+@item locale
+MULE: Localized menubars and localized splash screens.
-@item
-Your stack is getting trashed. Debugging this is hard; you have to do a
-binary-search type of narrowing down where the crash occurs, until you
-figure out exactly which line is causing the problem. Of course, this
-only works if the bug is highly reproducible. Also, in many cases if
-you run XEmacs from the debugger, the debugger can protect the stack
-somewhat. However, if the stack is being smashed, it is typically the
-case that there is a wild pointer somewhere in the program, often quite
-far from where the crash occurs.
+@item lookup
+Dictionary support. (This isn't an English dictionary program)
-@item
-If your stack trace has exactly one frame in it, with address 0x0, this
-could simply mean that XEmacs attempted to execute code at that address,
-e.g. through jumping to a null function pointer. Unfortunately, under
-those circumstances, GDB under Linux doesn't know how to get a stack
-trace. (Yes, this is the fourth Linux-related problem I've mentioned. I
-have no idea why GDB under Linux is so bogus. Complain to the GDB
-authors, or to comp.os.linux.development.system.) Again, you'll have to

-Two things you can do:
+Of course, input skills are portable across most applications. However,
+especially in modern GUI systems the habit of using bucky bits has
+fallen into sad disuse, and many XIM systems are poorly configured for
+use with Emacs. For example, the kinput2 input manager (a separate
+process providing an interface between Japanese dictionary servers such
+as Canna and Wnn, and the application) tends to gobble up keystrokes
+generating Meta characters. This means that to edit while using an XIM
+input method, you must toggle the input method off every time you want
+to use @kbd{M-f}. Your mileage may vary.
-1) C level:
+@emph{Library interfaces} are most common for Japanese, although Wnn
+supports Chinese (traditional and simplified) and Korean. There are
+Chinese and Korean input servers available, but we do not know of any
+patches for XEmacs to use them directly. You can use them via

+describe only the Japanese-oriented systems here. The advantage of
+these systems is that they are very powerful, and on platforms where
+they are available there is typically a wide range of applications that
+support them. Thus your input skills are portable across applications.
-When you see it going mad like this, you might want to use gdb from an
-'xterm' to attach to the running process and get a stack trace. To do
-this just run:
+Mule provides built-in interfaces to the following input methods: Wnn4,
+Wnn6, Canna, and SJ3. These can be configured at build time. There are
+patches available (no URL, sorry) to support the SKK server, as well.
+Wnn and SJ3 use the @code{egg} user interface. The interface for Canna
+is specialized to Canna.
-@example
-gdb /path/to/xemacs/xemacs ####
-@end example
+Wnn supports Japanese, Chinese and Korean. It is made by OMRON and Kyôto
+University. It is a powerful and complex system. Wnn4 is free and Wnn6
+is not. Wnn uses grammatical hints and probability of word association,
+so in principle Wnn can be cleverer than other methods.
-Where @code{####} is the process id of your xemacs, instead of
-specifying the core. When gdb attaches, the xemacs will stop [1] and
-you can type `where' in gdb to get a stack trace as usual. To get
-things moving again, you can just type `quit' in gdb. It'll tell you
-the program is running and ask if you want to quit anyways. Say 'y' and
-it'll quit and have your emacs continue from where it was at.
+Canna, made by NEC, supports only Japanese. It is a simple and powerful
+system. Canna uses only grammar, but its grammar and dictionary are
+quite sophisticated. So for standard modern Japanese, Canna seems
+cleverer than Wnn4. In addition, the UNIX version of Canna is free (now
+there is a Microsoft Windows version).

+MULE has evolved rapidly over the last few years, and the original third

-@unnumberedsubsec Q2.1.24: XEmacs won't start without network.
+MULE implementations are going to continue to evolve. Both GNU Emacs
+and XEmacs are working hard on Unicode support, which will involve new
+APIs and probably variations on old ones. For XEmacs 22, the old ISO
+2022-based system for recognizing encodings will be replaced by a much
+more flexible system, which should improve accuracy of automatic coding
+detections, but will also involve new APIs.

+@example
+(require 'un-define)
+(set-coding-priority-list '(utf-8))

-;;; Add things at the end, unconditionally
-(setq load-path (nconc load-path '("foo" "bar")))
-@end lisp
+in your init file to enable the UTF-8 coding system. You may wish to

+Mule doesn't have a Unicode charset internally, so there's nothing to

+then Korean. To change the priority ordering, use the command
+`un-define-change-charset-order'.

+It also means you can't use Unicode fonts directly, at least not without

-@samp{xemacs -name} really do? The reason I ask is that my window
-manager (fvwm) will make a window sticky and I use XEmacs to read my
-mail. I want that XEmacs window to be sticky, without having to use the
-window manager's function to set the window sticky. What gives?
+Where @samp{$prefix} is what you gave to the @samp{--prefix} flag to
+@file{configure}, and defaults to @file{/usr/local}.
-@samp{xemacs -name} sets the application name for the program (that is,
-the thing which normally comes from @samp{argv[0]}). Using @samp{-name}
-is the same as making a copy of the executable with that new name. The
-@code{WM_CLASS} property on each frame is set to the frame-name, and the
-application-class. So, if you did @samp{xemacs -name FOO} and then
-created a frame named @var{BAR}, you'd get an X window with WM_CLASS =
-@code{( "BAR", "Emacs")}. However, the resource hierarchy for this
-widget would be:
+If you have GNU tar you can use:
-@example
-Name: FOO .shell .container .BAR
-Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
-@end example
+@code{cd $prefix/lib/xemacs ; tar zxvf <tarballname>}
-instead of the default
+If you have the packages somewhere nonstandard and don't want to bother
+with @samp{$prefix} (for example, you're a developer and are compiling
+the packages yourself, and want your own private copy of everything),
+you can also directly specify this using @file{configure}. To do this
+with 21.5 and above use the @samp{--with-package-prefix} parameter to
+specify the directory under which you untarred the above tarballs.
+Under 21.4 and previous you need to use @samp{--package-path}. Using
+these options looks something like this:
@example
-Name: xemacs.shell .container .emacs
-Class: Emacs .TopLevelEmacsShell.EmacsManager.EmacsFrame
+ configure --package-path="~/.xemacs::/src/xemacs/site-packages:/src/xemacs/xemacs-packages:/src/xemacs/mule-packages" ...
@end example
+Under Windows, you need to place the above @samp{tar.gz} files in the
+directory specified using the @samp{PACKAGE_PREFIX} value in
+@file{nt/config.inc} and by default is @file{\Program Files\XEmacs}.
+(To untar a @samp{tar.gz} file you will need to use a utility such as
+WinZip, unless you have Cygwin or a similar environment installed, in
+which case the above Unix shell command should work fine.) If you want
+the packages somewhere else, just change @samp{PACKAGE_PREFIX}.
+
+Note that XEmacs finds the packages automatically anywhere underneath
+the directory tree where it expects to find the packages. All you
+need to do is put stuff there; you don't need to run any program to
+tell XEmacs to find the packges, or do anything of that sort.
+
+However, XEmacs will only notice newly installed packages when it
+starts up, so you will have to restart if you are already running
+XEmacs.
-It is arguable that the first element of WM_CLASS should be set to the
-application-name instead of the frame-name, but I think that's less
-flexible, since it does not give you the ability to have multiple frames
-with different WM_CLASS properties. Another possibility would be for
-the default frame name to come from the application name instead of
-simply being @samp{emacs}. However, at this point, making that change
-would be troublesome: it would mean that many users would have to make
-yet another change to their resource files (since the default frame name
-would suddenly change from @samp{emacs} to @samp{xemacs}, or whatever
-the executable happened to be named), so we'd rather avoid it.
-
-To make a frame with a particular name use:

+Because of the way XEmacs (and every other Emacsen, AFAIK) is built. The
+link gives you a bare-boned emacs (called temacs). temacs is then run,
+preloading some of the lisp files. The result is then dumped into a new

-Yes. Use @code{gnuclient -nw}. (Prior to 20.3, use the @code{gnuattach}
-program supplied with XEmacs instead.)
+Now, during the dump itself, the executable (code+data+symbols) is
+written on disk using a special unexec() function. This function is
+obviously heavily system dependent. And on some systems, it leads to an
+executable which, although valid, cannot be stripped without damage. If
+memory serves, this is especially the case for AIX binaries. On other
+architectures it might work OK.
-Also see @ref{Q5.0.12}.
+The Right Way to strip the emacs binary is to strip temacs prior to

+XEmacs can be built in several ways in the MS Windows environment.
-@lisp
-(setq next-line-add-newlines nil)
-@end lisp
+The standard way is what we call the "native" port. It uses the Win32
+API and has no connection with X whatsoever -- it does not require X
+libraries to build, nor does it require an X server to run. The native
+port is the most reliable version and provides the best graphical
+support. Almost all development is geared towards this version, and
+there is little reason not to use it.
-This has been the default setting in XEmacs for some time.
+The second way to build is the Cygwin port. It takes advantage of
+Cygnus emulation library under Win32. @xref{Q1.2.5, What are Cygwin
+and MinGW, and do I need them to run XEmacs?}, for more information.
-@node Q3.5.3, Q3.5.4, Q3.5.2, Customization

+build but does not require it at runtime. @xref{Q1.2.5, What are
+Cygwin and MinGW, and do I need them to run XEmacs?}, for more
+information.
-Add the following (Thanks to @email{mly@@adoc.xerox.com, Richard Mlynarik} and
-@email{wayne@@zen.cac.stratus.com, Wayne Newberry}) to @file{.emacs}:
+Finally, you might also be able to build the non-Cygwin, non-MinGW "X"
+port. This was actually the first version of XEmacs that ran under MS
+Windows, and although the code is still in XEmacs, it's essentially
+orphaned and it's unlikely it will compile without a lot of work. If
+you want an MS Windows versin of XEmacs that supports X, use the Cygwin
+version. (The X support there is actively maintained, so that Windows

+It's possible that a core file didn't get produced or the stack trace
+from gdb is garbage, in which case you're out of luck unless you can
+reproduce the bug. A nonexistent core file can happen in some
+circumstances on some operating systems, depending on what exactly
+triggered the crash. It's also possible, however, that your limits
+are set to turn them off. You may be able to reenable them using a
+command like @samp{unlimit coredumpsize} or @samp{ulimit -c}. (To find
+out how your limits are set, use the command @samp{limit}.) However, if
+you didn't explicitly set your limits this way, go complain to your
+system administrator and tell him not to disable core files by
+default.
+
+A garbaged stack trace can happen for various reasons. Some versions
+of gdb are broken on certain operating systems and aren't able to read
+the core file. It's also possible that the stack got overwritten
+during the crash. A very simple reason, however, is that your version
+of XEmacs was compiled without debugging information or had the
+debugging information stripped. A compilation with optimization can
+also result in partly or completely garbaged stack trace. In such
+cases, you will need to recompile XEmacs with debugging information
+and without optimization; @xref{Q2.4.4, How to debug an XEmacs problem
+with a debugger}. Note also that core files currently don't work at
+all under Cygwin, and the only way to get a backtrace is to run XEmacs
+from gdb.
+
+If you cannot get a backtrace from the core dump, but can reproduce
+the problem, try running XEmacs under gdb. The goal is to get clean C
+and Lisp backtraces and submit a bug report including full
+configuration information as described above, as this will greatly
+assist in the process of tracking down the bug. However, even partial
+information is better than none. The process of getting backtraces
+from gdb is described in detail in @ref{Q2.4.4, How to debug an XEmacs
+problem with a debugger}.
+If you're under Microsoft Windows, you're out of luck unless you happen
+to have a debugging aid installed on your system, for example Visual
+C++. In this case, the crash will result in a message giving you the
+option to enter a debugger (for example, by pressing @samp{Cancel}). Do
+this and locate the stack-trace window. (If your XEmacs was built
+without debugging information, the stack trace may not be very useful.)

+@itemize @bullet

+@samp{--debug=yes} and @samp{--error-checking=all}
+(@samp{--enable-debug=yes} and @samp{--enable-error-checking=all} on
+XEmacs 21.5 or later). This will make your XEmacs run somewhat slower,
+but you are a lot more likely to catch the problem earlier (closer to
+its source). It makes it a lot easier to determine what's going on with
+a debugger. The way to control the compiler flags is with the
+configuration option @samp{--cflags} (@samp{--with-cflags} in 21.5). If
+you have a recent version of 21.5, you should use
+@samp{--without-optimization} in preference to directly setting

+If it's not a true crash (@emph{i.e.}, XEmacs is hung, or a zombie
+process), or it's inconvenient to run XEmacs again because XEmacs is
+already running or is running in batch mode as part of a bunch of
+scripts, you may be able to attach to the existing process with your
+debugger. Under Unix and Mac OS X, the typical way to do this is to
+first use some variant of the @samp{ps} command to figure out the
+process ID of XEmacs, for example @samp{ps -auxww | grep xemacs} under
+a BSD variant, @samp{ps -elf | grep xemacs} under Linux or System V,
+or @samp{ps -aW | grep xemacs} under Cygwin. Then run

+Where @code{####} is the process id of your XEmacs. (If you're not
+sure, try using @samp{which xemacs}.) When gdb attaches, the xemacs
+will stop and you can type @samp{where} in gdb to get a stack trace as
+usual. To get things moving again, you can just type @samp{quit} in
+gdb. It'll tell you the program is running and ask if you want to
+quit anyways. Say @samp{y} and it'll quit and have your emacs

+buffered up and then sent to the server all at once. This greatly
+improves performance over a network but means that an error may not be
+reported until the server receives the commands, which can be long
+after XEmacs made the erroneous calls. For best results, you need to
+make the X server synchronous before getting the backtrace. This can

+@unnumberedsubsec Q2.4.6: XEmacs hangs when I try to do something.
+
+XEmacs might just be slow; some operations take a long time. XEmacs
+may also be waiting on a response from the network, for example when
+you are trying to send mail.
+
+You can usually interrupt XEmacs by typing @kbd{C-g}. If not (for
+example, Lisp code explicitly disabled this by setting
+@code{inhibit-quit}), you can use the "critical quit" mechanism by
+typing @kbd{Control-Shift-G}. This should also pop you into the
+debugger and give you a backtrace, which can tell you where the
+problem is (@pxref{Q2.4.4, How to debug an XEmacs problem with a
+debugger}). (Note that setting @code{debug-on-quit} or selecting
+@samp{Options->Troubleshooting->Debug on Quit} will also cause regular
+@kbd{C-g} to enter the debugger and give you a backtrace.)
+
+If you can't interrupt XEmacs this way, or for some reason XEmacs is
+not talking to the keyboard, you can try sending the @samp{SIGINT}
+signal using the @samp{kill} command.
+
+If the Lisp backtrace isn't enlightening, or if XEmacs is so hung that
+you can't interrupt it at all, you could try attaching to the process
+and getting a C stack backtrace. @xref{Q2.4.4, How to debug an XEmacs
+problem with a debugger}.
+
+@node Q2.4.7, Q2.4.8, Q2.4.6, Installation
+@unnumberedsubsec Q2.4.7: I get an error message when XEmacs is running in batch mode.
+
+Typically this happens when you are trying to compile some Elisp code.
+If you are doing this as part of XEmacs or the XEmacs packages, you
+should automatically get a backtrace, which can help you determine the
+source of the problem. In other cases, you can get equivalent results
+by setting the environment variable @samp{XEMACSDEBUG} to @samp{(setq
+stack-trace-on-error t load-always-display-messages t
+load-ignore-out-of-date-elc-files t load-show-full-path-in-messages
+t)} (this needs to be all on one line; to set an environment variable,
+use @samp{export XEMACSDEBUG='FOO'} under @samp{bash}, @samp{zsh},
+etc. or @samp{setenv XEMACSDEBUG 'FOO'} under @samp{csh} and
+@samp{tcsh}). @samp{XEMACSDEBUG} specifies Lisp code that will be
+executed at startup time.
+
+If the backtrace is not sufficiently useful in helping you diagnose
+the problem, you should consider using a debugger such as GDB.
+@xref{Q2.4.4, How to debug an XEmacs problem with a debugger}. You
+probably want to set a breakpoint on @code{signal_1}. Since such
+errors often occur during compiling, which is often triggered by a
+complex command run from a make suite, it may be easier to attach to
+the process once it's running.
+
+Under Microsoft Windows (and perhaps other operating systems), there is
+another useful trick you can do if you have configured with debugging
+support (configure option @samp{--debug} (@samp{--with-debug} in 21.5)
+or setting @samp{DEBUG_XEMACS} in @file{nt/config.inc}). Set the
+environment variable @samp{XEMACSDEBUG} (as described above) to
+@samp{(setq debug-on-error t)}. Then, when an error occurs
+noninteractively, instead of trying to invoke the Lisp debugger (which
+obviously won't work), XEmacs will break out to a C debugger using
+@code{(force-debugging-signal t)}. @emph{NOTE}: This runs
+@code{abort()}!!! (As well as and after executing INT 3 under MS
+Windows, which should invoke a debugger if it's active.) This is
+guaranteed to kill XEmacs! (But in this situation, XEmacs is about to
+die anyway, and if no debugger is present, this will usefully dump
+core.)

+
+First, try setting the variable @code{debug-emacs-events} to non-zero.
+This will output various information showing which events are being
+received and how they are being translated. This may show you, for
+example, that a key command is getting intercepted using

+output, including all parameters.)
+

+be useful in determining problems with quoting. (Under Unix, a process

+When building an application to be run in a Win32 environment, you must

+libraries linked into your application, the start up function that is
+run before control is handed over to your application, the entry point
+to your program, and how Windows normally invokes your program. (Console
+programs automatically get a console created for them at startup if
+their stdin/stdout don't point anywhere useful, which is the case when
+run from the GUI. This is a stupid design, of course -- instead, the
+console should get created only when the first I/O actually occurs!
+GUI programs have an equally stupid design: When called from
+@file{CMD.EXE}/@file{COMMAND.COM}, their stdin/stdout will be set to
+point nowhere useful, even though the command shell has its own
+stdin/stdout. It's as if someone who had learned a bit about stdio but
+had no actual knowledge of interprocess communication designed the
+scheme; unfortunately, the whole process-communication aspect of the
+Win32 API is equally badly designed.) For example, the entry point for a
+console app is "main" (which is what you'd expect for a C/C++ program),
+but the entry point for a "gui" app is "WinMain". This confuses and
+annoys a lot of programmers who've grown up on Unix systems, where the
+kernel doesn't really care whether your application is a gui program or
+not.

+For reasons not altogether clear, and are lost in the mists of time and

+made a console application partly because a console is needed in some

-tad more complicated than it has to be for XEmacs in order to make it
-more portable.
+However, this only works if there is a current X selection (the
+selection will be highlighted). The functionality I like is for the
+@kbd{paste} key to insert the current X selection if there is one,
+otherwise insert the contents of the clipboard. To do this you need to
+pass arguments to @code{x-insert-selection}. This is done by wrapping

+This binds the f18 key to a @dfn{generic} functional object. The
+interactive spec is required because only interactive functions can be
+bound to keys.
-Put the following in your @file{init.el}/@file{.emacs}:
+For the FAQ example you could use:
@lisp
-(setq isearch-highlight nil)
+(global-set-key [(control ?.)]
+ (lambda () (interactive) (scroll-up 1)))
+(global-set-key [(control ?;)]

-Starting with XEmacs-20.2 you can also change this with Customize. Type
-@kbd{M-x customize-variable @key{RET} isearch-highlight @key{RET}}.
-
-Note also that isearch-highlight affects query-replace and ispell.
-Instead of disabling isearch-highlight you may find that a better
-solution consists of customizing the @code{isearch} face.
+This is fine if you only need a few functions within the lambda body.

-@end table
+@lisp
+(global-set-key [(shift help)] 'help-command);; Help
+@end lisp
-The cut buffers are deprecated because managing them is even more
-inefficient than the clipboard notification protocol. The primary
-selection works fine for many users and applications, but is not very
-robust under intensive or sophisticated use.
+But it doesn't work alone. This is in the file @file{PROBLEMS} which
+should have come with your XEmacs installation: @emph{Emacs ignores the
+@kbd{help} key when running OLWM}.
-In Motif and MS Windows, a clipboard has become the primary means for
-managing cut and paste. These means that "modern" applications tend to
-be oriented toward a true clipboard, rather than the primary selection.
-(On Windows, there is nothing equivalent to the primary selection.)
-It's not that XEmacs doesn't support the simple primary selection
-method, it's that more and more other applications don't.
+OLWM grabs the @kbd{help} key, and retransmits it to the appropriate
+client using
+@iftex
+@*
+@end iftex
+@code{XSendEvent}. Allowing Emacs to react to synthetic
+events is a security hole, so this is turned off by default. You can
+enable it by setting the variable @code{x-allow-sendevents} to t. You
+can also cause fix this by telling OLWM to not grab the help key, with
+the null binding @code{OpenWindows.KeyboardCommand.Help:}.
-So the slowdown occurs because XEmacs now engages in the clipboard
-notification protocol on @emph{every} kill. This is especially slow on
-Motif.
+@node Q3.0.6, Q3.0.7, Q3.0.5, Editing

+One way is to use the package @code{x-compose}. Then you can use

-With most people running most clients and server on the same host, and
-many of the rest working over very fast communication, you may expect
-that the situation is not going to improve.
+Another way is to use the @code{iso-insert} package. Then you can use
+sequences like @kbd{C-x 8 " a} to get ä, etc.
-There are a number of workarounds. The most effective is to use a
-special command to do selection ownership only when you intend to paste
-to another application. Useful commands are @code{kill-primary-selection}
-and @code{copy-primary-selection}. These work only on text selected
-with the mouse (probably; experiment), and are bound by default to the
-@kbd{Cut} and @kbd{Copy}, respectively, buttons on the toolbar.
-@code{copy-primary-selection} is also bound to @kbd{C-Insert}. You can
-yank the clipboard contents with @code{yank-primary-selection}, bound to
-the @kbd{Paste} toolbar button and @kbd{Sh-Insert}.

-InfoDock is built atop the XEmacs variant of GNU Emacs and so has all of
-the power of Emacs, but with an easier to use and more comprehensive
-menu-based user interface. The bottom portion of this text describes
-how it differs from XEmacs and GNU Emacs from the Free Software

-InfoDock is aimed at people who want a free, turn-key productivity
-environment. Although InfoDock is customizable, it is not intended for
-people who like basic versions of Emacs which need to be customized
-extensively for local use; standard Emacs distributions are better for
-such uses. InfoDock is for those people who want a complete,
-pre-customized environment in one package, which they need not touch
-more than once or twice a year to update to new revisions.
+@unnumberedsec 4.0: Textual Fonts and Colors
-InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
-and Intel Linux systems. It is intended for use on a color display,
-although most features will work on monochrome monitors. Simply unpack
-InfoDock according to the instructions in the ID-INSTALL file and you
-are ready to run.
+@node Q4.0.1, Q4.0.2, Display, Display
+@unnumberedsubsec Q4.0.1: How do I specify a font?
-The InfoDock Manual is concise, yet sufficient as a user guide for users
-who have never used an Emacs-type editor before. For users who are
-already familiar with Emacs, it supplements the information in the GNU
-Emacs Manual.
+#### Update me.
-InfoDock menus are much more extensive and more mature than standard
-Emacs menus. Each menu offers a @samp{Manual} item which displays
-documentation associated with the menu's functions.
+In 21.4 and above, you can use the @samp{Options} menu to change the font.
+You can also do it in your init file, e.g. like this (for MS Windows):
-@noindent
-Four types of menubars are provided:
-@enumerate
-@item
-An extensive menubar providing access to global InfoDock commands.
-@item
-Mode-specific menubars tailored to the current major mode.
-@item
-A simple menubar for basic editing to help novices get started with InfoDock.
-@item
-The standard XEmacs menubar.
-@end enumerate
+@display
+ (set-face-font 'default "Lucida Console:Regular:10")
+ (set-face-font 'modeline "MS Sans Serif:Regular:10")
+@end display
-Most modes also include mode-specific popup menus. Additionally, region and
-rectangle popup menus are included.
+@node Q4.0.2, Q4.0.3, Q4.0.1, Display
+@unnumberedsubsec Q4.0.2: How do I set the text, menu and modeline fonts?
-@samp{Hyperbole}, the everyday information manager, is a core part of
-InfoDock. This provides context-sensitive mouse keys, a rolodex-type
-contact manager, programmable hypertext buttons, and an autonumbered
-outliner with embedded hyperlink anchors.
+#### Update me.
-The @samp{OO-Browser}, a multi-language object-oriented code browser, is a
-standard part of InfoDock.
+Note that you should use @samp{Emacs.} and not @samp{Emacs*} when
+setting face values.
-InfoDock saves a more extensive set of user options than other Emacs
-versions.
+In @file{.Xresources}:
-InfoDock inserts a useful file header in many file types, showing the
-author, summary, and last modification time of each file. A summary
-program can then be used to summarize all of the files in a directory,
-for easy MANIFEST file creation.
+@example
+Emacs.default.attributeFont: -*-*-medium-r-*-*-*-120-*-*-m-*-*-*
+Emacs*menubar*font: fixed
+Emacs.modeline.attributeFont: fixed
+@end example
-Your working set of buffers is automatically saved and restored (if you
-answer yes to a prompt) between InfoDock sessions.
+This is confusing because @samp{default} and @samp{modeline} are face
+names, and can be found listed with all faces in the current mode by
+using @kbd{M-x set-face-font (enter) ?}. They use the face-specific
+resource @samp{attributeFont}.
-Refined color choices for code highlighting are provided for both dark and
-light background display frames.
+On the other hand, @samp{menubar} is a normal X thing that uses the
+resource @samp{font}. With Motif it @emph{may be} necessary to use
+@samp{fontList} @emph{instead of} @samp{font}. In @emph{non-Motif}
+configurations with Mule it @emph{is} necessary to use @samp{fontSet}
+instead of @samp{font}. (Sorry, there just is no simple recipe here.)
-The @kbd{C-z} key prefix performs frame-based commands which parallel the
-@kbd{C-x} key prefix for window-based commands.
-
-The Smart Menu system is included for producing command menus on dumb
-terminals.

-Extensions and improvements to many areas of Emacs are included, such as:
-paragraph filling, mail reading with Rmail, shell handling, outlining, code
-highlighting and browsing, and man page browsing.

+I'm using Netscape (or another color grabber like XEmacs);

+
+Answer: No, but you can start Netscape before XEmacs, and it will use
+the closest available color if the colormap is full. You can also limit
+the number of colors Netscape uses, using the flags -mono, -ncols <#> or
+-install (for mono, limiting to <#> colors, or for using a private color
+map).
-Set your transfer mode to binary:
+If you have the money, another solution would be to use a truecolor or

+@unnumberedsubsec Q4.0.6: My tty supports color, but XEmacs doesn't use them.
-Turn off prompting:
+XEmacs tries to automatically determine whether your tty supports color,
+but sometimes guesses wrong. In that case, you can make XEmacs Do The
+Right Thing using this Lisp code:
-@example
- ftp> prompt
- Interactive mode off.
-@end example
+@lisp

-
-@enumerate
-@item
-The package has not been ported to XEmacs. This will typically happen
-when it uses GNU-Emacs-specific features, which make it fail under

-
-Porting a package to XEmacs can range from a trivial amount of change to

-@item
-The package has been decided not to be appropriate for XEmacs. It may
-have an equivalent or better replacement within XEmacs, in which case
-the developers may choose not to burden themselves with supporting an
-additional package.
-
-Each package bundled with XEmacs means more work for the maintainers,
-whether they want it or not. If you are ready to take over the
-maintenance responsibilities for the package you port, be sure to say
-so---we will more likely include it.
-
-@item
-The package simply hasn't been noted by the XEmacs development. If

-Note that Emacs by default starts up in buffer @code{*scratch*} in
-@code{initial-major-mode}, which defaults to

- (turn-on-auto-fill)))
+(add-hook 'lisp-mode-hook
+ (lambda ()
+ (set-face-background 'modeline "red" (current-buffer))))
@end lisp
-Note that after your init file is loaded, if
-@code{inhibit-startup-message} is @code{nil} (the default) and the
-startup buffer is @code{*scratch*} then the startup message will be
-inserted into @code{*scratch*}; it will be removed after a timeout by
-erasing the entire @code{*scratch*} buffer. Keep in mind this default
-usage of @code{*scratch*} if you desire any prior manipulation of
-@code{*scratch*} from within your Emacs init file. In particular,
-anything you insert into @code{*scratch*} from your init file will be
-later erased. Also, if you change the mode of the @code{*scratch*}
-buffer, be sure that this will not interfere with possible later
-insertion of the startup message (e.g. if you put @code{*scratch*} into
-a nonstandard mode that has automatic font lock rules, then the startup
-message might get fontified in a strange foreign manner, e.g. as code in
-some programming language).

+It is arguable that the first element of WM_CLASS should be set to the
+application-name instead of the frame-name, but I think that's less
+flexible, since it does not give you the ability to have multiple frames
+with different WM_CLASS properties. Another possibility would be for
+the default frame name to come from the application name instead of
+simply being @samp{emacs}. However, at this point, making that change
+would be troublesome: it would mean that many users would have to make
+yet another change to their resource files (since the default frame name
+would suddenly change from @samp{emacs} to @samp{xemacs}, or whatever
+the executable happened to be named), so we'd rather avoid it.
-Make sure your XEmacs was compiled with sound support, and then put this
-in your @file{init.el}/@file{.emacs}:
+To make a frame with a particular name use:
@lisp

+In his flavor of Emacs 20, Richard Stallman has renamed all the @samp{win32-*}
+symbols to @samp{w32-*}. Does XEmacs do the same?
-However, note that the package @code{cl-indent} that comes with
-XEmacs sets up this kind of indentation by default. @code{cl-indent}
-also knows about many other CL-specific forms. To use @code{cl-indent},
-one can do this:
+We consider such a move counter-productive, thus we do not use the
+@samp{w32} prefix. (His rather questionable justification was that he
+did not consider Windows to be a "winning" platform.) However, the name
+@samp{Win32} is not particularly descriptive outside the Windows world,
+and using just @samp{windows-} would be too generic. So we chose a
+compromise, the prefix @samp{mswindows-} for Windows-related variables
+and functions.
-@lisp
-(load "cl-indent")
-(setq lisp-indent-function (function common-lisp-indent-function))
-@end lisp
+Thus all the XEmacs variables and functions directly related to either
+the Windows GUI or OS are prefixed @samp{mswindows-} (except for a
+couple of debugging variables, prefixed @samp{debug-mswindows-}). From
+an architectural perspective, however, we believe that this is mostly a
+non-issue because there should be a very small number of
+window-systems-specific variables anyway. Whenever possible, we try to
+provide generic interfaces that apply to all window systems.

-Firstly there is an ftp site which describes X-faces and has the

-
-Then the steps are
-
-@enumerate
-@item
-Create 48x48x1 bitmap with your favorite tool
-
-@item
-Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,
-and then compile the face.
-
-@item
-@example
-cat file.xbm | xbm2ikon |compface > file.face
-@end example
-
-@item
-Then be sure to quote things that are necessary for emacs strings:
-
-@example
-cat ./file.face | sed 's/\\/\\\\/g'
-@iftex
-\ @*
-@end iftex
-| sed 's/\"/\\\"/g' > ./file.face.quoted
-@end example
-
-@item
-Then set up emacs to include the file as a mail header - there were a
-couple of suggestions here---either something like:
-
-@lisp
-(setq mail-default-headers
- "X-Face: @email{Ugly looking text string here}")
-@end lisp
-
-Or, alternatively, as:
-
-@lisp
-(defun mail-insert-x-face ()
- (save-excursion
- (goto-char (point-min))
- (search-forward mail-header-separator)
- (beginning-of-line)
- (insert "X-Face:")
- (insert-file-contents "~/.face")))
-
-(add-hook 'mail-setup-hook 'mail-insert-x-face)
-@end lisp
-@end enumerate
-
-However, 2 things might be wrong:
-
-Some versions of pbmtoicon produces some header lines that is not
-expected by the version of compface that I grabbed. So I found I had to
-include a @code{tail +3} in the pipeline like this:
-
-@example
-cat file.xbm | xbm2ikon | tail +3 |compface > file.face
-@end example
-
-Some people have also found that if one uses the @code{(insert-file)}
-method, one should NOT quote the face string using the sed script .
-
-It might also be helpful to use @email{stig@@hackvan.com, Stig's} script
-(included in the compface distribution at XEmacs.org) to do the
-conversion.

-Another area where we need help is the documentation: We need good
-documentation for building XEmacs and for using it. This FAQ is a
-small step in that direction.
+@dfn{Network Audio System} (NAS) is a client-server sound library for X.
-@node Q6.0.6, Q6.0.7, Q6.0.5, MS Windows
-@unnumberedsubsec Q6.0.6: What are Cygwin and MinGW, and do I need them to run XEmacs?
+@uref{http://radscan.com/nas.html}.
-To answer the second part of the question: No, you, you don't need
-Cygwin or MinGW to build or to run XEmacs. But if you have them and
-want to use them, XEmacs supports these environments.
+To build XEmacs with it, use the @file{configure} flag
+@samp{--with-sound=nas} (@samp{--enable-sound=nas} in 21.5 or later).
-(One important reason to support Cygwin is that it lets the MS Windows
-developers test out their code in a Unix environment without actually
-having to have a Unix machine around. For this reason alone, Cygwin
-support is likely to remain supported for a long time in XEmacs. Same
-goes for the X support under Cygwin, for the same reasons. MinGW
-support, on the other hand, depends on volunteers to keep it up to date;
-but this is generally not hard.)
+@dfn{Enlightened Sound Daemon} (ESD or EsounD) is yet another sound system.
-Cygwin is a set of tools providing Unix-like API on top of Win32.
-It makes it easy to port large Unix programs without significant
-changes to their source code. It is a development environment as well
-as a runtime environment.
+@uref{http://www.tux.org/~ricdude/EsounD.html}.
-When built with Cygwin, XEmacs supports all display types -- TTY, X &
-Win32 GUI, and can be built with support for all three simultaneously.
-If you build with Win32 GUI support then the Cygwin version uses the
-majority of the Windows-specific code, which is mostly related to
-display. If you want to build with X support you need X libraries (and
-an X server to display XEmacs on); see @ref{Q6.1.4}. TTY and Win32 GUI
-require no additional libraries beyond what comes standard with Cygwin.
+To build XEmacs with it, use the @file{configure} flag
+@samp{--with-sound=esd} (@samp{--enable-sound=esd} in 21.5 or later).
-The advantages of the Cygwin version are that it integrates well with
-the Cygwin environment for existing Cygwin users; uses configure so
-building with different features is very easy; and actively supports X &
-TTY. Furthermore, the entire Cygwin environment and compiler are free,
-whereas Visual C++ costs money.
+You can specify support for both with a flag like
+@samp{--with-sound=nas,esd} (@samp{--enable-sound=nas,esd} in 21.5 or
+later).
-The disadvantage is that it requires the whole Cygwin environment,
-whereas the native port requires only a suitable MS Windows compiler.
-Also, it follows the Unix filesystem and process model very closely
-(some will undoubtedly view this as an advantage).

+I'm having some trouble with sounds I've downloaded from sunsite. They

+@file{/dev/audio}, but XEmacs refuses to play them.
-MinGW is a collection of header files and import libraries that allow
-one to use GCC under the Cygwin environment to compile and produce
-exactly the same native Win32 programs that you can using Visual C++.
-Programs compiled with MinGW make use of the standard Microsoft runtime
-library @file{MSVCRT.DLL}, present on all Windows systems, and look,
-feel, and act like a standard Visual-C-produced application. (The only
-difference is the compiler.) This means that, unlike a
-standardly-compiled Cygwin application, no extra runtime support
-(e.g. Cygwin's @file{cygwin1.dll}) is required. This, along with the
-fact that GCC is free (and works in a nice Unix-y way in a nice Unix-y
-environment, for those die-hard Unix hackers out there), is the main
-advantage of MinGW. It is also potentially faster than Cygwin because
-it has less overhead when calling Windows, but you lose the POSIX
-emulation layer, which makes Unix programs harder to port. (But this is
-irrelevant for XEmacs since it's already ported to Win32.)

-port is the most reliable version and provides the best graphical

+ ;; Other possibilities for getting smtpmail to work:
+ ;;
+ ;; If for some reason you need to authenticate using the STARTTLS protocol
+ ;; (don't look into this unless you know what it is), use
+ ;; (setq smtpmail-starttls-credentials

+@unnumberedsubsec Q6.0.8: An MUA gets an error incorporating new mail.
+
+rmail and VM, and probably other MUA's as well, get new mail from
+your mailbox (called @file{/var/mail/$USER} or @file{/var/spool/mail/$USER}
+or something similar) using a program called @code{movemail}.
+This program interlocks with @code{/bin/mail} using the protocol
+defined by @code{/bin/mail}.
+
+There are various different protocols in general use, which you need to
+specify using the @samp{--mail-locking} option
+(@samp{--with-mail-locking} in 21.5 or later) to @file{configure}:
+
+@table @samp
+@item lockf
+POSIX file locking with @code{lockf()}
+@item flock
+BSD file locking with @code{flock()}
+@item dot
+To manipulate mail file @file{foo}, first create file @file{foo.lock}
+@item locking
+Use @code{locking()}, Microsoft's renamed @code{flock()}
+@item mmdf
+Use @code{lk_open()} and @code{lk_close()} as defined by the Multi-channel
+Memo Distribution Facility
+@item pop
+Retrieve mail using POP (the Post Office Protocol). This is the
+default for Cygwin/MinGW.
+@end table
+
+@strong{IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR
+SYSTEM, YOU CAN LOSE MAIL!}
+
+Usually the value is correctly determined automatically:
+@file{configure} tries to detect the method in use, and defaults exist
+on systems for which this doesn't work.
+
+However, if you run into problems incorporating new mail, it may be
+because an incorrect method is being used.
+
+If your system uses the lock file protocol, and permissions are set
+so that ordinary users cannot write lock files in the mail spool
+directory, you may need to make @file{movemail} setgid to a
+suitable group such as @samp{mail}. You can use these commands (as
+root):
+
+@example
+chgrp mail movemail
+chmod 2755 movemail
+@end example
+
+If you are using the @samp{pop} locking method, @file{movemail} must
+be setuid root.
+
+Installation normally copies movemail from the build directory to an
+installation directory which is usually under @file{/usr/local/lib}.
+The installed copy of @file{movemail} is usually in the directory
+@file{/usr/local/lib/xemacs-VERSION/TARGET} (for example,
+@file{/usr/local/lib/xemacs-21.4.15/i686-pc-cygwin}). You must change
+the group and mode of the installed copy; changing the group and mode
+of the build directory copy is ineffective.

+
+Firstly there is an ftp site which describes X-faces and has the
+associated tools mentioned below, at
+@uref{http://ftp.cs.indiana.edu/pub/faces/}.
+
+Then the steps are
+
+@enumerate
+@item
+Create 48x48x1 bitmap with your favorite tool
+
+@item
+Convert to "icon" format using one of xbm2ikon, pbmtoicon, etc.,
+and then compile the face.
+
+@item
+@example
+cat file.xbm | xbm2ikon |compface > file.face
+@end example
+
+@item
+Then be sure to quote things that are necessary for emacs strings:
+
+@example
+cat ./file.face | sed 's/\\/\\\\/g'
+@iftex
+\ @*
+@end iftex
+| sed 's/\"/\\\"/g' > ./file.face.quoted
+@end example
+
+@item
+Then set up emacs to include the file as a mail header - there were a
+couple of suggestions here---either something like:
+
+@lisp
+(setq mail-default-headers
+ "X-Face: @email{Ugly looking text string here}")
+@end lisp
+
+Or, alternatively, as:
+
+@lisp
+(defun mail-insert-x-face ()
+ (save-excursion
+ (goto-char (point-min))
+ (search-forward mail-header-separator)
+ (beginning-of-line)
+ (insert "X-Face:")
+ (insert-file-contents "~/.face")))
+
+(add-hook 'mail-setup-hook 'mail-insert-x-face)
+@end lisp
+@end enumerate
+
+However, 2 things might be wrong:
+
+Some versions of pbmtoicon produces some header lines that is not
+expected by the version of compface that I grabbed. So I found I had to
+include a @code{tail +3} in the pipeline like this:
+
+@example
+cat file.xbm | xbm2ikon | tail +3 |compface > file.face
+@end example
+
+Some people have also found that if one uses the @code{(insert-file)}
+method, one should NOT quote the face string using the sed script .
+
+It might also be helpful to use @email{stig@@hackvan.com, Stig's} script
+xbm2face (included in the compface distribution at XEmacs.org) to do the
+conversion.

+@email{clerik@@naggum.no, Erik Naggum} writes;
+
+@quotation
+Emacs has a legacy of keyboards that produced characters with modifier
+bits, and therefore map a variety of input systems into this scheme even
+today. XEmacs is instead optimized for X events. This causes an
+incompatibility in the way key sequences are specified, but both Emacs
+and XEmacs will accept a key sequence as a vector of lists of modifiers
+that ends with a key, e.g., to bind @kbd{M-C-a}, you would say
+@code{[(meta control a)]} in both Emacsen. XEmacs has an abbreviated
+form for a single key, just (meta control a). Emacs has an abbreviated
+form for the Control and the Meta modifiers to string-characters (the
+ASCII characters), as in @samp{\M-\C-a}. XEmacs users need to be aware
+that the abbreviated form works only for one-character key sequences,
+while Emacs users need to be aware that the string-character is rather
+limited. Specifically, the string-character can accommodate only 256
+different values, 128 of which have the Meta modifier and 128 of which
+have not. In each of these blocks, only 32 characters have the Control
+modifier. Whereas @code{[(meta control A)]} differs from @code{[(meta
+control a)]} because the case differs, @samp{\M-\C-a} and @samp{\M-\C-A}
+do not. Programmers are advised to use the full common form, both
+because it is more readable and less error-prone, and because it is
+supported by both Emacsen.
+@end quotation
+
+Another (even safer) way to be sure of the key-sequences is to use the
+@code{read-kbd-macro} function, which takes a string like @samp{C-c
+<up>}, and converts it to the internal key representation of the Emacs
+you use. The function is available both on XEmacs and GNU Emacs.

+@unnumberedsubsec Q7.1.2: Can I generate "fake" keyboard events?
+
+I wonder if there is an interactive function that can generate
+@dfn{fake} keyboard events. This way, I could simply map them inside
+XEmacs.
+
+This seems to work:
+
+@lisp
+(defun cg--generate-char-event (ch)
+ "Generate an event, as if ch has been typed"
+ (dispatch-event (character-to-event ch)))
+
+;; Backspace and Delete stuff
+(global-set-key [backspace]
+ (lambda () (interactive) (cg--generate-char-event 127)))

+
+@node Q7.1.3, Q7.1.4, Q7.1.2, Advanced
+@unnumberedsubsec Q7.1.3: Could you explain @code{read-kbd-macro} in more detail?
+
+The @code{read-kbd-macro} function returns the internal Emacs
+representation of a human-readable string (which is its argument).
+Thus:
+
+@lisp
+(read-kbd-macro "C-c C-a")
+@result{} [(control ?c) (control ?a)]
+
+(read-kbd-macro "C-c C-. <up>")
+@result{} [(control ?c) (control ?.) up]
+@end lisp
+
+In GNU Emacs the same forms will be evaluated to what GNU Emacs
+understands internally---the sequences @code{"\C-x\C-c"} and @code{[3
+67108910 up]}, respectively.
+
+The exact @dfn{human-readable} syntax is defined in the docstring of
+@code{edmacro-mode}. I'll repeat it here, for completeness.
+
+@quotation
+Format of keyboard macros during editing:
+
+Text is divided into @dfn{words} separated by whitespace. Except for
+the words described below, the characters of each word go directly as
+characters of the macro. The whitespace that separates words is
+ignored. Whitespace in the macro must be written explicitly, as in
+@kbd{foo @key{SPC} bar @key{RET}}.
+
+@itemize @bullet
+@item
+The special words @kbd{RET}, @kbd{SPC}, @kbd{TAB}, @kbd{DEL}, @kbd{LFD},
+@kbd{ESC}, and @kbd{NUL} represent special control characters. The
+words must be written in uppercase.
+
+@item
+A word in angle brackets, e.g., @code{<return>}, @code{<down>}, or
+@code{<f1>}, represents a function key. (Note that in the standard
+configuration, the function key @code{<return>} and the control key
+@key{RET} are synonymous.) You can use angle brackets on the words
+@key{RET}, @key{SPC}, etc., but they are not required there.
+
+@item
+Keys can be written by their @sc{ascii} code, using a backslash followed
+by up to six octal digits. This is the only way to represent keys with
+codes above \377.
+

+
+In most cases, not noticeable. Besides, there's no avoiding
+@code{let}---you have to bind your local variables, after all. Some
+pose a question whether to nest @code{let}s, or use one @code{let} per

+@unnumberedsubsec Q7.1.5: What is the recommended use of @code{setq}?
+
+@itemize @bullet
+@item Global variables
+
+You will typically @code{defvar} your global variable to a default
+value, and use @code{setq} to set it later.
+
+It is never a good practice to @code{setq} user variables (like
+@code{case-fold-search}, etc.), as it ignores the user's choice
+unconditionally. Note that @code{defvar} doesn't change the value of a
+variable if it was bound previously. If you wish to change a
+user-variable temporarily, use @code{let}:
+
+@lisp
+(let ((case-fold-search nil))
+ ... ; code with searches that must be case-sensitive
+ ...)
+@end lisp
+
+You will notice the user-variables by their docstrings beginning with an
+asterisk (a convention).
+
+@item Local variables
+
+Bind them with @code{let}, which will unbind them (or restore their
+previous value, if they were bound) after exiting from the @code{let}
+form. Change the value of local variables with @code{setq} or whatever
+you like (e.g. @code{incf}, @code{setf} and such). The @code{let} form
+can even return one of its local variables.
+
+Typical usage:
+
+@lisp
+;; iterate through the elements of the list returned by
+;; `hairy-function-that-returns-list'
+(let ((l (hairy-function-that-returns-list)))
+ (while l
+ ... do something with (car l) ...
+ (setq l (cdr l))))
+@end lisp
+
+Another typical usage includes building a value simply to work with it.
+
+@lisp
+;; Build the mode keymap out of the key-translation-alist
+(let ((inbox (file-truename (expand-file-name box)))
+ (i 0))
+ ... code dealing with inbox ...
+ inbox)
+@end lisp
+
+This piece of code uses the local variable @code{inbox}, which becomes
+unbound (or regains old value) after exiting the form. The form also
+returns the value of @code{inbox}, which can be reused, for instance:
+
+@lisp
+(setq foo-processed-inbox
+ (let .....))

+@node Q7.1.6, Q7.1.7, Q7.1.5, Advanced
+@unnumberedsubsec Q7.1.6: What is the typical misuse of @code{setq}?
+
+A typical misuse is probably @code{setq}ing a variable that was meant to
+be local. Such a variable will remain bound forever, never to be
+garbage-collected. For example, the code doing:
+
+@lisp
+(defun my-function (whatever)
+ (setq a nil)
+ ... build a large list ...
+ ... and exit ...)
+@end lisp
+
+does a bad thing, as @code{a} will keep consuming memory, never to be
+unbound. The correct thing is to do it like this:
+
+@lisp
+(defun my-function (whatever)
+ (let (a) ; default initialization is to nil
+ ... build a large list ...
+ ... and exit, unbinding `a' in the process ...)
+@end lisp
+
+Not only is this prettier syntactically, but it makes it possible for
+Emacs to garbage-collect the objects which @code{a} used to reference.
+
+Note that even global variables should not be @code{setq}ed without
+@code{defvar}ing them first, because the byte-compiler issues warnings.
+The reason for the warning is the following:
+
+@lisp
+(defun flurgoze nil) ; ok, global internal variable
+...
+
+(setq flurghoze t) ; ops! a typo, but semantically correct.
+ ; however, the byte-compiler warns.
+
+While compiling toplevel forms:

+It shouldn't. Here is what Dave Gillespie has to say about cl.el
+performance:
+
+@quotation
+Many of the advanced features of this package, such as @code{defun*},
+@code{loop}, and @code{setf}, are implemented as Lisp macros. In
+byte-compiled code, these complex notations will be expanded into
+equivalent Lisp code which is simple and efficient. For example, the
+forms
+
+@lisp
+(incf i n)
+(push x (car p))
+@end lisp
+
+are expanded at compile-time to the Lisp forms
+
+@lisp
+(setq i (+ i n))
+(setcar p (cons x (car p)))
+@end lisp
+
+which are the most efficient ways of doing these respective operations
+in Lisp. Thus, there is no performance penalty for using the more
+readable @code{incf} and @code{push} forms in your compiled code.
-@end itemize
+@emph{Interpreted} code, on the other hand, must expand these macros
+every time they are executed. For this reason it is strongly
+recommended that code making heavy use of macros be compiled. (The
+features labelled @dfn{Special Form} instead of @dfn{Function} in this
+manual are macros.) A loop using @code{incf} a hundred times will
+execute considerably faster if compiled, and will also garbage-collect
+less because the macro expansion will not have to be generated, used,
+and thrown away a hundred times.
+You can find out how a macro expands by using the @code{cl-prettyexpand}
+function.

+Thanks to @email{james@@xemacs.org, Jerry James}, XEmacs 21.5.18 and

+gives you @dfn{bignums} (arbitrary precision integers), @dfn{ratios}
+(arbitrary precision fractions), and @dfn{bigfloats} (arbitrary
+precision floating point numbers). GNU MP is better-supported by XEmacs
+at the time of writing (2004-04-06). BSD MP support does not include
+ratios or bigfloats, and it throws errors that aren't understood.
-In future versions, some of these features might be turned on by
-default in the MS Windows environment.
+In most cases, bignum support should be transparent to users and Lisp

+fixnums to bignums and back in pure integer arithmetic, and for GNU MP,
+from floats to bigfloats. (Bigfloats must be explicitly coerced to
+other types, even if they are exactly representable by less precise
+types.) The Lisp reader and printer have been enhanced to handle
+bignums, as have the mathematical functions. Rationals (fixnums,
+bignums, and ratios) are printed using the @samp{%d}, @samp{%o},
+@samp{%x}, and @samp{%u} format conversions. The read syntax for ratios

-@unnumberedsubsec Q6.3.1: Does XEmacs rename all the @samp{win32-*} symbols to @samp{w32-*}?
+Most problems with AUCTeX are one of two things:
-In his flavor of Emacs 20, Richard Stallman has renamed all the @samp{win32-*}
-symbols to @samp{w32-*}. Does XEmacs do the same?
+@itemize @bullet
+@item
+The TeX-lisp-directory in @file{tex-site.el} and the makefile don't
+match.
-We consider such a move counter-productive, thus we do not use the
-@samp{w32} prefix. (His rather questionable justification was that he
-did not consider Windows to be a "winning" platform.) However, the name
-@samp{Win32} is not particularly descriptive outside the Windows world,
-and using just @samp{windows-} would be too generic. So we chose a
-compromise, the prefix @samp{mswindows-} for Windows-related variables
-and functions.
+Fix: make sure you configure AUCTeX properly @strong{before} installing.
-Thus all the XEmacs variables and functions directly related to either
-the Windows GUI or OS are prefixed @samp{mswindows-} (except for a
-couple of debugging variables, prefixed @samp{debug-mswindows-}). From
-an architectural perspective, however, we believe that this is mostly a
-non-issue because there should be a very small number of
-window-systems-specific variables anyway. Whenever possible, we try to
-provide generic interfaces that apply to all window systems.
+@item
+You have an old version of easymenu.el in your path.
-@c not true:
-@c The user variables
-@c that share functionality with existing NT Emacs variables are be named
-@c with our convention, but we provide the GNU Emacs names as
-@c compatibility aliases.
+Fix: use @code{locate-library} and remove old versions to make sure it

+@unnumberedsubsec Q8.2.3: What is/was Energize?
-When building an application to be run in a Win32 environment, you must
-state which sub-system it is to run in. Valid subsystems include
-"console" and "gui". The subsystem you use affects the run time
-libraries linked into your application, the start up function that is
-run before control is handed over to your application, the entry point
-to your program, and how Windows normally invokes your program. (Console
-programs automatically get a console created for them at startup if
-their stdin/stdout don't point anywhere useful, which is the case when
-run from the GUI. This is a stupid design, of course -- instead, the
-console should get created only when the first I/O actually occurs!
-GUI programs have an equally stupid design: When called from
-@file{CMD.EXE}/@file{COMMAND.COM}, their stdin/stdout will be set to
-point nowhere useful, even though the command shell has its own
-stdin/stdout. It's as if someone who had learned a bit about stdio but
-had no actual knowledge of interprocess communication designed the
-scheme; unfortunately, the whole process-communication aspect of the
-Win32 API is equally badly designed.) For example, the entry point for a
-console app is "main" (which is what you'd expect for a C/C++ program),
-but the entry point for a "gui" app is "WinMain". This confuses and
-annoys a lot of programmers who've grown up on Unix systems, where the
-kernel doesn't really care whether your application is a gui program or
-not.
+The "Energize Programming System" was a C and C++ development environment
+sold by Lucid, Inc. It was the reason why Lucid Emacs, now XEmacs, was
+created in the first place. Unfortunately, Lucid went out of business in
+1994. The rights to sell it in Japan were purchased by INS
+Engineering (which briefly employed Stig Hackvan aka Jonathan
+Stigelman to work on Japanese support for XEmacs, in late 1994 and
+early 1995) and Tartan bought the rights to sell it in the rest of the
+world. However, INS is not selling Energize at this point and may or
+may not have ever done so; Tartan certainly never did.
-For reasons not altogether clear, and are lost in the mists of time and
-tradition, XEmacs on Win32 started out as a console application, and
-therefore a console was automatically created for it. (It may have been
-made a console application partly because a console is needed in some
-circumstances, especially under Win95, to interrupt, terminate, or send
-signals to a child process, and because of the bogosity mentioned above
-with GUI programs and the standard command shell. Currently, XEmacs
-just creates and immediately hides a console when necessary, and
-works around the "no useful stdio" problem by creating its own console
-window as necessary to display messages in.)

+
+@uref{http://sourceforge.net/projects/infodock/, InfoDock} is an
+integrated productivity toolset, mainly aimed at technical people,
+hosted at SourceForge.
+InfoDock is built atop the XEmacs variant of GNU Emacs and so has all of
+the power of Emacs, but with an easier to use and more comprehensive
+menu-based user interface. The bottom portion of this text describes
+how it differs from XEmacs and GNU Emacs from the Free Software
+Foundation.
-@node Q6.3.4, Q6.4.1, Q6.3.3, MS Windows
-@unnumberedsubsec Q6.3.4: What is the porting team doing at the moment?
+InfoDock is aimed at people who want a free, turn-key productivity
+environment. Although InfoDock is customizable, it is not intended for
+people who like basic versions of Emacs which need to be customized
+extensively for local use; standard Emacs distributions are better for
+such uses. InfoDock is for those people who want a complete,
+pre-customized environment in one package, which they need not touch
+more than once or twice a year to update to new revisions.
-(as of June 2001)
+InfoDock is pre-built for SPARC SunOS/Solaris systems, PA-RISC HP-UX,
+and Intel Linux systems. It is intended for use on a color display,
+although most features will work on monochrome monitors. Simply unpack
+InfoDock according to the instructions in the ID-INSTALL file and you
+are ready to run.
-The porting team is continuing work on the MS Windows-specific code.
-Major projects are the development of Mule (internationalization)
-support for Windows and the improvement of the widget support (better
-support for dialog boxes, buttons, edit fields, and similar UI
-elements).
+The InfoDock Manual is concise, yet sufficient as a user guide for users
+who have never used an Emacs-type editor before. For users who are
+already familiar with Emacs, it supplements the information in the GNU
+Emacs Manual.
+InfoDock menus are much more extensive and more mature than standard
+Emacs menus. Each menu offers a @samp{Manual} item which displays
+documentation associated with the menu's functions.

+Four types of menubars are provided:
+@enumerate

+Most modes also include mode-specific popup menus. Additionally, region and
+rectangle popup menus are included.
-XEmacs relies on a process called "dumping" to generate a working
-executable. Under MS-Windows this process effectively fixes the memory
-addresses of information in the executable. When XEmacs starts up it tries
-to reserve these memory addresses so that the dumping process can be
-reversed -- putting the information back at the correct addresses.
-Unfortunately some .DLLs (for instance the soundblaster driver) occupy
-memory addresses that can conflict with those needed by the dumped XEmacs
-executable. In this instance XEmacs will fail to start without any
-explanation. Note that this is extremely machine specific.
+@samp{Hyperbole}, the everyday information manager, is a core part of
+InfoDock. This provides context-sensitive mouse keys, a rolodex-type
+contact manager, programmable hypertext buttons, and an autonumbered
+outliner with embedded hyperlink anchors.
-21.1.10 includes a fix for this that makes more intelligent guesses
-about which memory addresses will be free, and this should cure the

occasionally be updated to reflect new information about versions which
are no longer being revised by the XEmacs Project. The primary purpose
is advice on compatibility of older XEmacsen with new packages and
updated versions of packages, but bug fixes (which will not be applied
to released XEmacsen, but users can apply themselves) are also accepted.

+@unnumberedsubsec Q10.0.2: XEmacs won't start on Windows in XEmacs 21.1.
+
+XEmacs relies on a process called "dumping" to generate a working
+executable. Under MS-Windows this process effectively fixes the memory
+addresses of information in the executable. When XEmacs starts up it tries
+to reserve these memory addresses so that the dumping process can be
+reversed -- putting the information back at the correct addresses.
+Unfortunately some .DLLs (for instance the soundblaster driver) occupy
+memory addresses that can conflict with those needed by the dumped XEmacs
+executable. In this instance XEmacs will fail to start without any
+explanation. Note that this is extremely machine specific.
+
+21.1.10 includes a fix for this that makes more intelligent guesses
+about which memory addresses will be free, and this should cure the
+problem for most people. 21.4 implements "portable dumping", which
+eliminates the problem altogether. We recommend you use the 21.4
+binaries, but you can use the 21.1 binaries if you are very paranoid
+about stability. @xref{Q1.1.2, Are binaries available?}.
