+ A buffer-local variable has a buffer-local binding associated with a +particular buffer. The binding is in effect when that buffer is +current; otherwise, it is not in effect. If you set the variable while +a buffer-local binding is in effect, the new value goes in that binding, +so the global binding is unchanged; this means that the change is +visible in that buffer alone. + + A variable may have buffer-local bindings in some buffers but not in +others. The global binding is shared by all the buffers that don't have +their own bindings. Thus, if you set the variable in a buffer that does +not have a buffer-local binding for it, the new value is visible in all +buffers except those with buffer-local bindings. (Here we are assuming +that there are no `let'-style local bindings to complicate the issue.) + + The most common use of buffer-local bindings is for major modes to +change variables that control the behavior of commands. For example, C +mode and Lisp mode both set the variable `paragraph-start' to specify +that only blank lines separate paragraphs. They do this by making the +variable buffer-local in the buffer that is being put into C mode or +Lisp mode, and then setting it to the new value for that mode. + + The usual way to make a buffer-local binding is with +`make-local-variable', which is what major mode commands use. This +affects just the current buffer; all other buffers (including those yet +to be created) continue to share the global value. + + A more powerful operation is to mark the variable as "automatically +buffer-local" by calling `make-variable-buffer-local'. You can think +of this as making the variable local in all buffers, even those yet to +be created. More precisely, the effect is that setting the variable +automatically makes the variable local to the current buffer if it is +not already so. All buffers start out by sharing the global value of +the variable as usual, but any `setq' creates a buffer-local binding +for the current buffer. The new value is stored in the buffer-local +binding, leaving the (default) global binding untouched. The global +value can no longer be changed with `setq'; you need to use +`setq-default' to do that. + + Local variables in a file you edit are also represented by +buffer-local bindings for the buffer that holds the file within XEmacs. +*Note Auto Major Mode::. + + +File: lispref.info, Node: Creating Buffer-Local, Next: Default Value, Prev: Intro to Buffer-Local, Up: Buffer-Local Variables + +Creating and Deleting Buffer-Local Bindings +------------------------------------------- + + - Command: make-local-variable variable + This function creates a buffer-local binding in the current buffer + for VARIABLE (a symbol).

This is how Lisp -programs get into Lisp from files of Lisp code. We call the text the -"read syntax" of the object.

This - map is also the function definition of `Control-X-prefix'. - - * `ctl-x-4-map' is used for events that follow `C-x 4'. - - * `ctl-x-5-map' is used for events that follow `C-x 5'. - - * The prefix keys `C-x n', `C-x r' and `C-x a' use keymaps that have - no special name. - - * `esc-map' is an evil hack that is present for compatibility - purposes with Emacs 18. Defining a key in `esc-map' is equivalent - to defining the same key in `global-map' but with the - prefix added. You should _not_ use this in your code. (This map is - also the function definition of `ESC-prefix'.) - - The binding of a prefix key is the keymap to use for looking up the -events that follow the prefix key. (It may instead be a symbol whose -function definition is a keymap. The effect is the same, but the symbol -serves as a name for the prefix key.) Thus, the binding of `C-x' is -the symbol `Control-X-prefix', whose function definition is the keymap -for `C-x' commands. (The same keymap is also the value of `ctl-x-map'.) - - Prefix key definitions can appear in any active keymap. The -definitions of `C-c', `C-x', `C-h' and as prefix keys appear in -the global map, so these prefix keys are always available. Major and -minor modes can redefine a key as a prefix by putting a prefix key -definition for it in the local map or the minor mode's map. *Note -Active Keymaps::. - - If a key is defined as a prefix in more than one active map, then its -various definitions are in effect merged: the commands defined in the -minor mode keymaps come first, followed by those in the local map's -prefix definition, and then by those from the global map. - - In the following example, we make `C-p' a prefix key in the local -keymap, in such a way that `C-p' is identical to `C-x'. Then the -binding for `C-p C-f' is the function `find-file', just like `C-x C-f'. -The key sequence `C-p 6' is not found in any active keymap. - - (use-local-map (make-sparse-keymap)) - => nil - (local-set-key "\C-p" ctl-x-map) - => nil - (key-binding "\C-p\C-f") - => find-file - - (key-binding "\C-p6") - => nil - - - Function: define-prefix-command symbol &optional mapvar - This function defines SYMBOL as a prefix command: it creates a - keymap and stores it as SYMBOL's function definition. Storing the - symbol as the binding of a key makes the key a prefix key that has - a name. If optional argument MAPVAR is not specified, it also - sets SYMBOL as a variable, to have the keymap as its value. (If - MAPVAR is given and is not `t', its value is stored as the value - of SYMBOL.) The function returns SYMBOL. - - In Emacs version 18, only the function definition of SYMBOL was - set, not the value as a variable. - - -File: lispref.info, Node: Active Keymaps, Next: Key Lookup, Prev: Prefix Keys, Up: Keymaps - -Active Keymaps -============== - - XEmacs normally contains many keymaps; at any given time, just a few -of them are "active" in that they participate in the interpretation of -user input. These are the global keymap, the current buffer's local -keymap, and the keymaps of any enabled minor modes. - - The "global keymap" holds the bindings of keys that are defined -regardless of the current buffer, such as `C-f'. The variable -`global-map' holds this keymap, which is always active. - - Each buffer may have another keymap, its "local keymap", which may -contain new or overriding definitions for keys. The current buffer's -local keymap is always active except when `overriding-local-map' or -`overriding-terminal-local-map' overrides it. Extents and text -properties can specify an alternative local map for certain parts of the -buffer; see *Note Extents and Events::. - - Each minor mode may have a keymap; if it does, the keymap is active -when the minor mode is enabled. - - The variable `overriding-local-map' and -`overriding-terminal-local-map', if non-`nil', specify other local -keymaps that override the buffer's local map and all the minor mode -keymaps. - - All the active keymaps are used together to determine what command to -execute when a key is entered. XEmacs searches these maps one by one, -in order of decreasing precedence, until it finds a binding in one of -the maps. - - More specifically: - - For key-presses, the order of keymaps searched is: - - * the `keymap' property of any extent(s) or text properties at point; - - * any applicable minor-mode maps; - - * the current local map of the current buffer; - - * the current global map. - - For mouse-clicks, the order of keymaps searched is: - - * the current local map of the `mouse-grabbed-buffer' if any; - - * the `keymap' property of any extent(s) at the position of the click - (this includes modeline extents); - - * the `modeline-map' of the buffer corresponding to the modeline - under the mouse (if the click happened over a modeline); - - * the value of `toolbar-map' in the current buffer (if the click - happened over a toolbar); - - * the current local map of the buffer under the mouse (does not - apply to toolbar clicks); - - * any applicable minor-mode maps; - - * the current global map. - - Note that if `overriding-local-map' or -`overriding-terminal-local-map' is non-`nil', _only_ those two maps and -the current global map are searched. - - The procedure for searching a single keymap is called "key lookup"; -see *Note Key Lookup::. - - Since every buffer that uses the same major mode normally uses the -same local keymap, you can think of the keymap as local to the mode. A -change to the local keymap of a buffer (using `local-set-key', for -example) is seen also in the other buffers that share that keymap. - - The local keymaps that are used for Lisp mode, C mode, and several -other major modes exist even if they have not yet been used. These -local maps are the values of the variables `lisp-mode-map', -`c-mode-map', and so on. For most other modes, which are less -frequently used, the local keymap is constructed only when the mode is -used for the first time in a session. - - The minibuffer has local keymaps, too; they contain various -completion and exit commands. *Note Intro to Minibuffers::. - - *Note Standard Keymaps::, for a list of standard keymaps. - - - Function: current-keymaps &optional event-or-keys - This function returns a list of the current keymaps that will be - searched for bindings.

When running +under a window manager, XEmacs can tell the difference between, for +example, the keystrokes `control-h', `control-shift-h', and +`backspace'. You can, in fact, bind different commands to each of +these. + + A "key sequence" is a set of keystrokes. A "keystroke" is a keysym +and some set of modifiers (such as and ). A "keysym" +is what is printed on the keys on your keyboard. + + A keysym may be represented by a symbol, or (if and only if it is +equivalent to an ASCII character in the range 32 - 255) by a character +or its equivalent ASCII code. The `A' key may be represented by the +symbol `A', the character `?A', or by the number 65. The `break' key +may be represented only by the symbol `break'. + + A keystroke may be represented by a list: the last element of the +list is the key (a symbol, character, or number, as above) and the +preceding elements are the symbolic names of modifier keys (, +, , , , and ). Thus, the sequence +`control-b' is represented by the forms `(control b)', `(control ?b)', +and `(control 98)'. A keystroke may also be represented by an event +object, as returned by the `next-command-event' and `read-key-sequence' +functions. + + Note that in this context, the keystroke `control-b' is _not_ +represented by the number 2 (the ASCII code for `^B') or the character +`?\^B'. See below. + + The modifier is somewhat of a special case. You should not +(and cannot) use `(meta shift a)' to mean `(meta A)', since for +characters that have ASCII equivalents, the state of the shift key is +implicit in the keysym (`a' vs. `A'). You also cannot say `(shift =)' +to mean `+', as that sort of thing varies from keyboard to keyboard. +The modifier is for use only with characters that do not have a +second keysym on the same key, such as `backspace' and `tab'. + + A key sequence is a vector of keystrokes. As a degenerate case, +elements of this vector may also be keysyms if they have no modifiers. +That is, the `A' keystroke is represented by all of these forms: + + A ?A 65 (A) (?A) (65) + [A] [?A] [65] [(A)] [(?A)] [(65)] + + the `control-a' keystroke is represented by these forms: + + (control A) (control ?A) (control 65) + [(control A)] [(control ?A)] [(control 65)] + + the key sequence `control-c control-a' is represented by these forms: + + [(control c) (control a)] [(control ?c) (control ?a)] + [(control 99) (control 65)] etc. + + Mouse button clicks work just like keypresses: `(control button1)' +means pressing the left mouse button while holding down the control +key. `[(control c) (shift button3)]' means `control-c', hold , +click right. + + Commands may be bound to the mouse-button up-stroke rather than the +down-stroke as well. `button1' means the down-stroke, and `button1up' +means the up-stroke. Different commands may be bound to the up and +down strokes, though that is probably not what you want, so be careful. + + For backward compatibility, a key sequence may also be represented by +a string. In this case, it represents the key sequence(s) that would +produce that sequence of ASCII characters in a purely ASCII world. For +example, a string containing the ASCII backspace character, `"\^H"', +would represent two key sequences: `(control h)' and `backspace'. +Binding a command to this will actually bind both of those key +sequences. Likewise for the following pairs: + + control h backspace + control i tab + control m return + control j linefeed + control [ escape + control @ control space + + After binding a command to two key sequences with a form like + + (define-key global-map "\^X\^I" 'command-1) + +it is possible to redefine only one of those sequences like so: + + (define-key global-map [(control x) (control i)] 'command-2) + (define-key global-map [(control x) tab] 'command-3) + + Of course, all of this applies only when running under a window +system.

It +can contain arbitrary text or graphics. It could be considered a +generalization of a toolbar, although toolbars are not currently +implemented using gutters. + + In XEmacs, a gutter can be displayed along any of the four edges of +the frame, and two or more different edges can be displaying gutters +simultaneously. The contents, thickness, and visibility of the gutters +can be controlled separately, and the values can be per-buffer, +per-frame, etc., using specifiers (*note Specifiers::). + + Normally, there is one gutter displayed in a frame. Usually, this is +the default gutter, containing buffer tabs, but modes cab override this +and substitute their own gutter. This default gutter is usually +positioned along the top of the frame, but this can be changed using +`set-default-gutter-position'. + + Note that, for each of the gutter properties (contents, thickness, +and visibility), there is a separate specifier for each of the four +gutter positions (top, bottom, left, and right), and an additional +specifier for the "default" gutter, i.e. the gutter whose position is +controlled by `set-default-gutter-position'. The way this works is +that `set-default-gutter-position' arranges things so that the +appropriate position-specific specifiers for the default position +inherit from the corresponding default specifiers. That way, if the +position-specific specifier does not give a value (which it usually +doesn't), then the value from the default specifier applies. If you +want to control the default gutter, you just change the default +specifiers, and everything works. A package such as VM that wants to +put its own gutter in a different location from the default just sets +the position-specific specifiers, and if the user sets the default +gutter to the same position, it will just not be visible. + + +File: lispref.info, Node: Creating Gutter, Next: Gutter Descriptor Format, Prev: Gutter Intro, Up: Gutter + +Creating Gutter +=============== + + - Function: make-gutter-specifier spec-list + Return a new `gutter' specifier object with the given specification + list.

The first + glyph, which must be provided, is the glyph used to display the + gutter button when it is in the "up" (not pressed) state. The + optional second glyph is for displaying the button when it is in + the "down" (pressed) state. The optional third glyph is for when + the button is disabled. The last three glyphs are for displaying + the button in the "up", "down", and "disabled" states, + respectively, but are used when the user has called for captioned + gutter buttons (using `gutter-buttons-captioned-p'). The function + `gutter-make-button-list' is useful in creating these glyph lists. + + * Even if you do not provide separate down-state and disabled-state + glyphs, the user will still get visual feedback to indicate which + state the button is in. Buttons in the up-state are displayed + with a shadowed border that gives a raised appearance to the + button. Buttons in the down-state are displayed with shadows that + give a recessed appearance. Buttons in the disabled state are + displayed with no shadows, giving a 2-d effect. + + * If some of the gutter glyphs are not provided, they inherit as + follows: + + UP: up + DOWN: down -> up + DISABLED: disabled -> up + CAP-UP: cap-up -> up + CAP-DOWN: cap-down -> cap-up -> down -> up + CAP-DISABLED: cap-disabled -> cap-up -> disabled -> up + + * The second element FUNCTION is a function to be called when the + gutter button is activated (i.e. when the mouse is released over + the gutter button, if the press occurred in the gutter). It can + be any form accepted by `call-interactively', since this is how it + is invoked. + + * The third element ENABLED-P specifies whether the gutter button is + enabled (disabled buttons do nothing when they are activated, and + are displayed differently; see above). It should be either a + boolean or a form that evaluates to a boolean. + + * The fourth element HELP, if non-`nil', should be a string.

Its value should enable or disable the mode (`nil' to - disable; anything else to enable.) We call this the "mode - variable". - - This variable is used in conjunction with the `minor-mode-alist' to - display the minor mode name in the modeline. It can also enable - or disable a minor mode keymap. Individual commands or hooks can - also check the variable's value. - - If you want the minor mode to be enabled separately in each buffer, - make the variable buffer-local. - - * Define a command whose name is the same as the mode variable. Its - job is to enable and disable the mode by setting the variable. - - The command should accept one optional argument. If the argument - is `nil', it should toggle the mode (turn it on if it is off, and - off if it is on). Otherwise, it should turn the mode on if the - argument is a positive integer, a symbol other than `nil' or `-', - or a list whose CAR is such an integer or symbol; it should turn - the mode off otherwise. - - Here is an example taken from the definition of - `transient-mark-mode'. It shows the use of `transient-mark-mode' - as a variable that enables or disables the mode's behavior, and - also shows the proper way to toggle, enable or disable the minor - mode based on the raw prefix argument value. - - (setq transient-mark-mode - (if (null arg) (not transient-mark-mode) - (> (prefix-numeric-value arg) 0))) - - * Add an element to `minor-mode-alist' for each minor mode (*note - Modeline Variables::).

These strings must be - short so that there is room for several of them at once. - - When you add an element to `minor-mode-alist', use `assq' to check - for an existing element, to avoid duplication.

The modeline contains information about the buffer, -such as its name, associated file, depth of recursive editing, and the -major and minor modes. - - This section describes how the contents of the modeline are -controlled. It is in the chapter on modes because much of the -information displayed in the modeline relates to the enabled major and -minor modes. - - `modeline-format' is a buffer-local variable that holds a template -used to display the modeline of the current buffer. All windows for -the same buffer use the same `modeline-format' and their modelines -appear the same (except for scrolling percentages and line numbers). - - The modeline of a window is normally updated whenever a different -buffer is shown in the window, or when the buffer's modified-status -changes from `nil' to `t' or vice-versa.

The data structure is called a "modeline -construct", and it is built in recursive fashion out of simpler modeline -constructs. The same data structure is used for constructing frame -titles (*note Frame Titles::). - - - Variable: modeline-format - The value of this variable is a modeline construct with overall - responsibility for the modeline format. The value of this variable - controls which other variables are used to form the modeline text, - and where they appear. - - A modeline construct may be as simple as a fixed string of text, but -it usually specifies how to use other variables to construct the text. -Many of these variables are themselves defined to have modeline -constructs as their values. - - The default value of `modeline-format' incorporates the values of -variables such as `mode-name' and `minor-mode-alist'. Because of this, -very few modes need to alter `modeline-format'. For most purposes, it -is sufficient to alter the variables referenced by `modeline-format'. - - A modeline construct may be a string, symbol, glyph, generic -specifier, list or cons cell. - -`STRING' - A string as a modeline construct is displayed verbatim in the mode - line except for "`%'-constructs". Decimal digits after the `%' - specify the field width for space filling on the right (i.e., the - data is left justified). *Note %-Constructs::. - -`SYMBOL' - A symbol as a modeline construct stands for its value. The value - of SYMBOL is processed as a modeline construct, in place of - SYMBOL. However, the symbols `t' and `nil' are ignored; so is any - symbol whose value is void. - - There is one exception: if the value of SYMBOL is a string, it is - displayed verbatim: the `%'-constructs are not recognized. - -`GLYPH' - A glyph is displayed as is. - -`GENERIC-SPECIFIER' - A GENERIC-SPECIFIER (i.e. a specifier of type `generic') stands - for its instance. The instance of GENERIC-SPECIFIER is computed - in the current window using the equivalent of `specifier-instance' - and the value is processed. - -`(STRING REST...) or (LIST REST...)' - A list whose first element is a string or list means to process - all the elements recursively and concatenate the results. This is - the most common form of mode line construct. - -`(SYMBOL THEN ELSE)' - A list whose first element is a symbol is a conditional. Its - meaning depends on the value of SYMBOL. If the value is non-`nil', - the second element, THEN, is processed recursively as a modeline - element. But if the value of SYMBOL is `nil', the third element, - ELSE, is processed recursively. You may omit ELSE; then the mode - line element displays nothing if the value of SYMBOL is `nil'. - -`(WIDTH REST...)' - A list whose first element is an integer specifies truncation or - padding of the results of REST. The remaining elements REST are - processed recursively as modeline constructs and concatenated - together. Then the result is space filled (if WIDTH is positive) - or truncated (to -WIDTH columns, if WIDTH is negative) on the - right. - - For example, the usual way to show what percentage of a buffer is - above the top of the window is to use a list like this: `(-3 - "%p")'. - -`(EXTENT REST...)' - A list whose car is an extent means the cdr of the list is - processed normally but the results are displayed using the face of - the extent, and mouse clicks over this section are processed using - the keymap of the extent.

You may - want to change this in modes such as Rmail that do not behave like - a "normal" XEmacs. - - - 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 - `display-time-string', which holds a string containing the time and - load information. - - The `%M' construct substitutes the value of `global-mode-string', - but this is obsolete, since the variable is included directly in - the modeline. - - - Variable: mode-name - This buffer-local variable holds the "pretty" name of the current - buffer's major mode.

For +example, Auto Fill mode may be used in any major mode that permits text +insertion. To be general, a minor mode must be effectively independent +of the things major modes do. + + A minor mode is often much more difficult to implement than a major +mode. One reason is that you should be able to activate and deactivate +minor modes in any order. A minor mode should be able to have its +desired effect regardless of the major mode and regardless of the other +minor modes in effect. + + Often the biggest problem in implementing a minor mode is finding a +way to insert the necessary hook into the rest of XEmacs.

Several of the major mode conventions apply to minor +modes as well: those regarding the name of the mode initialization +function, the names of global symbols, and the use of keymaps and other +tables. + + In addition, there are several conventions that are specific to +minor modes. + + * Make a variable whose name ends in `-mode' to represent the minor + mode. Its value should enable or disable the mode (`nil' to + disable; anything else to enable.) We call this the "mode + variable". + + This variable is used in conjunction with the `minor-mode-alist' to + display the minor mode name in the modeline. It can also enable + or disable a minor mode keymap. Individual commands or hooks can + also check the variable's value. + + If you want the minor mode to be enabled separately in each buffer, + make the variable buffer-local. + + * Define a command whose name is the same as the mode variable. Its + job is to enable and disable the mode by setting the variable. + + The command should accept one optional argument. If the argument + is `nil', it should toggle the mode (turn it on if it is off, and + off if it is on). Otherwise, it should turn the mode on if the + argument is a positive integer, a symbol other than `nil' or `-', + or a list whose CAR is such an integer or symbol; it should turn + the mode off otherwise. + + Here is an example taken from the definition of + `transient-mark-mode'. It shows the use of `transient-mark-mode' + as a variable that enables or disables the mode's behavior, and + also shows the proper way to toggle, enable or disable the minor + mode based on the raw prefix argument value. + + (setq transient-mark-mode + (if (null arg) (not transient-mark-mode) + (> (prefix-numeric-value arg) 0))) + + * Add an element to `minor-mode-alist' for each minor mode (*note + Modeline Variables::). This element should be a list of the + following form: + + (MODE-VARIABLE STRING) + + Here MODE-VARIABLE is the variable that controls enabling of the + minor mode, and STRING is a short string, starting with a space, + to represent the mode in the modeline. These strings must be + short so that there is room for several of them at once. + + When you add an element to `minor-mode-alist', use `assq' to check + for an existing element, to avoid duplication.

By default, it is the - character `?\^H' (ASCII 8), which is `C-h'. When XEmacs reads this - character, if `help-form' is non-`nil' Lisp expression, it - evaluates that expression, and displays the result in a window if - it is a string. - - `help-char' can be a character or a key description such as `help' - or `(meta h)'. - - Usually the value of `help-form''s value is `nil'.

You may make the - buffer current or display it in a window if you wish, but this - function does not do so. - - When `find-file-noselect' uses an existing buffer, it first - verifies that the file has not changed since it was last visited or - saved in that buffer. If the file has changed, then this function - asks the user whether to reread the changed file. If the user says - `yes', any changes previously made in the buffer are lost. - - If `find-file-noselect' needs to create a buffer, and there is no - file named FILENAME, it displays the message `New file' in the - echo area, and leaves the buffer empty. - - If NO-WARN is non-`nil', various warnings that XEmacs normally - gives (e.g. if another buffer is already visiting FILENAME but - FILENAME has been removed from disk since that buffer was created) - are suppressed. - - The `find-file-noselect' function calls `after-find-file' after - reading the file (*note Subroutines of Visiting::).

Version numbers are found mostly in -directory lists. - - - Function: file-name-directory filename - This function returns the directory part of FILENAME (or `nil' if - FILENAME does not include a directory part).

On Unix, this is simple: a -directory name ends in a slash, whereas the directory's name as a file -lacks that slash. On VMS, the relationship is more complicated. - - The difference between a directory name and its name as a file is -subtle but crucial. When an XEmacs variable or function argument is -described as being a directory name, a file name of a directory is not -acceptable. - - The following two functions convert between directory names and file -names.

File names in XEmacs are represented as strings. The +functions that operate on a file all expect a file name argument. + + In addition to operating on files themselves, XEmacs Lisp programs +often need to operate on the names; i.e., to take them apart and to use +part of a name to construct related file names. This section describes +how to manipulate file names. + + The functions in this section do not actually access files, so they +can operate on file names that do not refer to an existing file or +directory. + + On MS-DOS, these functions understand MS-DOS file-name syntax as +well as Unix syntax. This is so that all the standard Lisp libraries +can specify file names in Unix syntax and work properly on all systems +without change.

To specify a +file, you must specify the directory and the file's name within that +directory. Therefore, XEmacs considers a file name as having two main +parts: the "directory name" part, and the "nondirectory" part (or "file +name within the directory"). Either part may be empty. Concatenating +these two parts reproduces the original file name. + + On Unix, the directory part is everything up to and including the +last slash; the nondirectory part is the rest. + + For some purposes, the nondirectory part is further subdivided into +the name proper and the "version number". On Unix, only backup files +have version numbers in their names. + + - Function: file-name-directory filename + This function returns the directory part of FILENAME (or `nil' if + FILENAME does not include a directory part).

A directory is a +kind of file, and it has a file name, which is related to the directory +name but not identical to it. (This is not quite the same as the usual +Unix terminology.) These two different names for the same entity are +related by a syntactic transformation. On Unix, this is simple: a +directory name ends in a slash, whereas the directory's name as a file +lacks that slash. + + The difference between a directory name and its name as a file is +subtle but crucial. When an XEmacs variable or function argument is +described as being a directory name, a file name of a directory is not +acceptable. + + The following two functions convert between directory names and file +names. They do nothing special with environment variable substitutions +such as `$HOME', and the constructs `~', and `..'. + + - Function: file-name-as-directory filename + This function returns a string representing FILENAME in a form + that the operating system will interpret as the name of a + directory.

The function + `abbreviate-file-name' performs these substitutions. + + You can set this variable in `site-init.el' to describe the + abbreviations appropriate for your site. + + Here's an example, from a system on which file system `/home/fsf' + and so on are normally accessed through symbolic links named `/fsf' + and so on. + + (("^/home/fsf" .

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 - 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 - begins and ends with hash marks (`#') is a possible auto-save file - name.

Be sure to - change `auto-save-file-name-p' in a corresponding way. - - - 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', - so auto-save files have distinct names that are created by - `make-auto-save-file-name'. - - When you change the value of this variable, the value does not take - effect until the next time auto-save mode is reenabled in any given - 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 - 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 - 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 - 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 - 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 - This normal hook is run whenever an auto-save is about to happen. - - - 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 - 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. - - Normally, if any buffers are auto-saved, a message that says - `Auto-saving...' is displayed in the echo area while auto-saving is - going on. However, if NO-MESSAGE is non-`nil', the message is - inhibited. - - If CURRENT-ONLY is non-`nil', only the current buffer is - auto-saved. - - - 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 - 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 - 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 - 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 - size, and turn off auto-saving in response. - - If it is -1, that means auto-saving is temporarily shut off in this - buffer due to a substantial deletion. Explicitly saving the buffer - stores a positive value in this variable, thus reenabling - auto-saving. Turning auto-save mode off or on also alters this - variable. - - - 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 - that has auto-saving enabled. The first line gives the name of - the visited file (it's empty if the buffer has none), and the - second gives the name of the auto-save file. - - If XEmacs exits normally, it deletes this file. If XEmacs - crashes, you can look in the file to find all the auto-save files - that might contain work that was otherwise lost. The - `recover-session' command uses these files. - - The default name for this file is in your home directory and - starts with `.saves-'. It also contains the XEmacs process ID and - the host name. - - -File: lispref.info, Node: Reverting, Prev: Auto-Saving, Up: Backups and Auto-Saving - -Reverting -========= - - If you have made extensive changes to a file and then change your -mind about them, you can get rid of them by reading in the previous -version of the file with the `revert-buffer' command. *Note Reverting -a Buffer: (emacs)Reverting. - - - Command: revert-buffer &optional check-auto-save noconfirm - This command replaces the buffer text with the text of the visited - file on disk. This action undoes all changes since the file was - visited or saved. - - If the argument CHECK-AUTO-SAVE is non-`nil', and the latest - auto-save file is more recent than the visited file, - `revert-buffer' asks the user whether to use that instead. - Otherwise, it always uses the text of the visited file itself. - Interactively, CHECK-AUTO-SAVE is set if there is a numeric prefix - argument. - - Normally, `revert-buffer' asks for confirmation before it changes - the buffer; but if the argument NOCONFIRM is non-`nil', - `revert-buffer' does not ask for confirmation. - - Reverting tries to preserve marker positions in the buffer by - using the replacement feature of `insert-file-contents'. If the - buffer contents and the file contents are identical before the - revert operation, reverting preserves all the markers. If they - are not identical, reverting does change the buffer; then it - preserves the markers in the unchanged text (if any) at the - beginning and end of the buffer. Preserving any additional - markers would be problematical. - - You can customize how `revert-buffer' does its work by setting these -variables--typically, as buffer-local variables. - - - Variable: revert-buffer-function - The value of this variable is the function to use to revert this - buffer. If non-`nil', it is called as a function with no - arguments to do the work of reverting. If the value is `nil', - reverting works the usual way. - - Modes such as Dired mode, in which the text being edited does not - consist of a file's contents but can be regenerated in some other - fashion, give this variable a buffer-local value that is a - function to regenerate the contents. - - - Variable: revert-buffer-insert-file-contents-function - The value of this variable, if non-`nil', is the function to use to - insert the updated contents when reverting this buffer. The - 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 normal hook is run by `revert-buffer' before actually - inserting the modified contents--but only if - `revert-buffer-function' is `nil'. - - Font Lock mode uses this hook to record that the buffer contents - are no longer fontified. - - - Variable: after-revert-hook - This normal hook is run by `revert-buffer' after actually inserting - the modified contents--but only if `revert-buffer-function' is - `nil'. - - Font Lock mode uses this hook to recompute the fonts for the - updated buffer contents. - - -File: lispref.info, Node: Buffers, Next: Windows, Prev: Backups and Auto-Saving, Up: Top - -Buffers -******* - - A "buffer" is a Lisp object containing text to be edited.

The term is also used to refer to a Lisp object -that represents that screen area in XEmacs Lisp. It should be clear -from the context which is meant. - - XEmacs groups windows into frames. A frame represents an area of -screen available for XEmacs to use. Each frame always contains at least -one window, but you can subdivide it vertically or horizontally into -multiple nonoverlapping Emacs windows. - - In each frame, at any time, one and only one window is designated as -"selected within the frame". The frame's cursor appears in that -window. At ant time, one frame is the selected frame; and the window -selected within that frame is "the selected window". The selected -window's buffer is usually the current buffer (except when `set-buffer' -has been used). *Note Current Buffer::. - - For practical purposes, a window exists only while it is displayed in -a frame. Once removed from the frame, the window is effectively deleted -and should not be used, _even though there may still be references to -it_ from other Lisp objects. Restoring a saved window configuration is -the only way for a window no longer on the screen to come back to life. -(*Note Deleting Windows::.) - - Each window has the following attributes: - - * containing frame - - * window height - - * window width - - * window edges with respect to the frame or screen - - * the buffer it displays - - * position within the buffer at the upper left of the window - - * amount of horizontal scrolling, in columns - - * point - - * the mark - - * how recently the window was selected - - Users create multiple windows so they can look at several buffers at -once. Lisp libraries use multiple windows for a variety of reasons, but -most often to display related information. In Rmail, for example, you -can move through a summary buffer in one window while the other window -shows messages one at a time as they are reached. - - The meaning of "window" in XEmacs is similar to what it means in the -context of general-purpose window systems such as X, but not identical. -The X Window System places X windows on the screen; XEmacs uses one or -more X windows as frames, and subdivides them into Emacs windows.

The term is also used to refer to a Lisp object +that represents that screen area in XEmacs Lisp. It should be clear +from the context which is meant. + + XEmacs groups windows into frames. A frame represents an area of +screen available for XEmacs to use. Each frame always contains at least +one window, but you can subdivide it vertically or horizontally into +multiple nonoverlapping Emacs windows. + + In each frame, at any time, one and only one window is designated as +"selected within the frame". The frame's cursor appears in that +window. At ant time, one frame is the selected frame; and the window +selected within that frame is "the selected window". The selected +window's buffer is usually the current buffer (except when `set-buffer' +has been used). *Note Current Buffer::. + + For practical purposes, a window exists only while it is displayed in +a frame. Once removed from the frame, the window is effectively deleted +and should not be used, _even though there may still be references to +it_ from other Lisp objects. Restoring a saved window configuration is +the only way for a window no longer on the screen to come back to life. +(*Note Deleting Windows::.) + + Each window has the following attributes: + + * containing frame + + * window height + + * window width + + * window edges with respect to the frame or screen + + * the buffer it displays + + * position within the buffer at the upper left of the window + + * amount of horizontal scrolling, in columns + + * point + + * the mark + + * how recently the window was selected + + Users create multiple windows so they can look at several buffers at +once. Lisp libraries use multiple windows for a variety of reasons, but +most often to display related information. In Rmail, for example, you +can move through a summary buffer in one window while the other window +shows messages one at a time as they are reached. + + The meaning of "window" in XEmacs is similar to what it means in the +context of general-purpose window systems such as X, but not identical. +The X Window System places X windows on the screen; XEmacs uses one or +more X windows as frames, and subdivides them into Emacs windows. When +you use XEmacs on a character-only terminal, XEmacs treats the whole +terminal screen as one frame. + + Most window systems support arbitrarily located overlapping windows. +In contrast, Emacs windows are "tiled"; they never overlap, and +together they fill the whole screen or frame. Because of the way in +which XEmacs creates new windows and resizes them, you can't create +every conceivable tiling of windows on an Emacs frame. *Note Splitting +Windows::, and *Note Size of Window::. + + *Note Display::, for information on how the contents of the window's +buffer are displayed in the window. + + - Function: windowp object + This function returns `t' if OBJECT is a window. + + +File: lispref.info, Node: Splitting Windows, Next: Deleting Windows, Prev: Basic Windows, Up: Windows + +Splitting Windows +================= + + The functions described here are the primitives used to split a +window into two windows. Two higher level functions sometimes split a +window, but not always: `pop-to-buffer' and `display-buffer' (*note +Displaying Buffers::). + + The functions described here do not accept a buffer as an argument. +The two "halves" of the split window initially display the same buffer +previously visible in the window that was split. + + - Function: one-window-p &optional nomini which-frames which-devices + This function returns non-`nil' if there is only one window. The + argument NOMINI, if non-`nil', means don't count the minibuffer + even if it is active; otherwise, the minibuffer window is + included, if active, in the total number of windows which is + compared against one. + + The remaining arguments controls which set of windows are counted, + as with `next-window'. + + - Command: split-window &optional window size horizontal + This function splits WINDOW into two windows. The original window + WINDOW remains the selected window, but occupies only part of its + former screen area. The rest is occupied by a newly created + window which is returned as the value of this function. + + If HORIZONTAL is non-`nil', then WINDOW splits into two side by + side windows. The original window WINDOW keeps the leftmost SIZE + columns, and gives the rest of the columns to the new window. + Otherwise, it splits into windows one above the other, and WINDOW + keeps the upper SIZE lines and gives the rest of the lines to the + new window. The original window is therefore the left-hand or + upper of the two, and the new window is the right-hand or lower. + + If WINDOW is omitted or `nil', then the selected window is split. + If SIZE is omitted or `nil', then WINDOW is divided evenly into + two parts.

Vertical +scrolling involves selection of a contiguous portion of text to display. +Horizontal scrolling causes part of each line to go off screen. The +amount of horizontal scrolling is therefore specified as a number of +columns rather than as a position in the buffer. It has nothing to do +with the display-start position returned by `window-start'. + + Usually, no horizontal scrolling is in effect; then the leftmost +column is at the left edge of the window. In this state, scrolling to +the right is meaningless, since there is no data to the left of the +screen to be revealed by it; so this is not allowed. Scrolling to the +left is allowed; it scrolls the first columns of text off the edge of +the window and can reveal additional columns on the right that were +truncated before. Once a window has a nonzero amount of leftward +horizontal scrolling, you can scroll it back to the right, but only so +far as to reduce the net horizontal scroll to zero. There is no limit +to how far left you can scroll, but eventually all the text will +disappear off the left edge. + + - Command: scroll-left &optional count + This function scrolls the selected window COUNT columns to the + left (or to the right if COUNT is negative).

The text that -remains addressable is called the "accessible portion" of the buffer. - - Narrowing is specified with two buffer positions which become the -beginning and end of the accessible portion. For most editing commands -and most Emacs primitives, these positions replace the values of the -beginning and end of the buffer. While narrowing is in effect, no text -outside the accessible portion is displayed, and point cannot move -outside the accessible portion. - - Values such as positions or line numbers, which usually count from -the beginning of the buffer, do so despite narrowing, but the functions -which use them refuse to operate on text that is inaccessible. - - The commands for saving buffers are unaffected by narrowing; they -save the entire buffer regardless of any narrowing. - - - Command: narrow-to-region start end &optional buffer - This function sets the accessible portion of BUFFER to start at - START and end at END. Both arguments should be character - positions.

It is - equivalent to the following expression: - - (narrow-to-region 1 (1+ (buffer-size))) - - BUFFER defaults to the current buffer if omitted. - - - Special Form: save-restriction body... - This special form saves the current bounds of the accessible - portion, evaluates the BODY forms, and finally restores the saved - bounds, thus restoring the same state of narrowing (or absence - thereof) formerly in effect. The state of narrowing is restored - even in the event of an abnormal exit via `throw' or error (*note - Nonlocal Exits::). Therefore, this construct is a clean way to - narrow a buffer temporarily. - - The value returned by `save-restriction' is that returned by the - last form in BODY, or `nil' if no body forms were given. - - *Caution:* it is easy to make a mistake when using the - `save-restriction' construct. Read the entire description here - before you try it. - - If BODY changes the current buffer, `save-restriction' still - restores the restrictions on the original buffer (the buffer whose - restrictions it saved from), but it does not restore the identity - of the current buffer. - - `save-restriction' does _not_ restore point and the mark; use - `save-excursion' for that. If you use both `save-restriction' and - `save-excursion' together, `save-excursion' should come first (on - the outside). Otherwise, the old point value would be restored - with temporary narrowing still in effect. If the old point value - were outside the limits of the temporary narrowing, this would - fail to restore it accurately. - - The `save-restriction' special form records the values of the - beginning and end of the accessible portion as distances from the - beginning and end of the buffer. In other words, it records the - amount of inaccessible text before and after the accessible - portion. - - This method yields correct results if BODY does further narrowing. - However, `save-restriction' can become confused if the body widens - and then make changes outside the range of the saved narrowing. - When this is what you want to do, `save-restriction' is not the - right tool for the job.

The -marker can be used to represent a position in the functions that -require one, just as an integer could be used. *Note Positions::, for -a complete description of positions. - - A marker has two attributes: the marker position, and the marker -buffer. The marker position is an integer that is equivalent (at a -given time) to the marker as a position in that buffer. But the -marker's position value can change often during the life of the marker. -Insertion and deletion of text in the buffer relocate the marker. The -idea is that a marker positioned between two characters remains between -those two characters despite insertion and deletion elsewhere in the -buffer. Relocation changes the integer equivalent of the marker. - - Deleting text around a marker's position leaves the marker between -the characters immediately before and after the deleted text. Inserting -text at the position of a marker normally leaves the marker in front of -the new text--unless it is inserted with `insert-before-markers' (*note -Insertion::). - - Insertion and deletion in a buffer must check all the markers and -relocate them if necessary. This slows processing in a buffer with a -large number of markers. For this reason, it is a good idea to make a -marker point nowhere if you are sure you don't need it any more. -Unreferenced markers are garbage collected eventually, but until then -will continue to use time if they do point somewhere. - - Because it is common to perform arithmetic operations on a marker -position, most of the arithmetic operations (including `+' and `-') -accept markers as arguments. In such cases, the marker stands for its -current position. - - Note that you can use extents to achieve the same functionality, and -more, as markers. (Markers were defined before extents, which is why -they both continue to exist.) A zero-length extent with the -`detachable' property removed is almost identical to a marker. (*Note -Extent Endpoints::, for more information on zero-length extents.) - - In particular: - - * In order to get marker-like behavior in a zero-length extent, the - `detachable' property must be removed (otherwise, the extent will - disappear when text near it is deleted) and exactly one endpoint - must be closed (if both endpoints are closed, the extent will - expand to contain text inserted where it is located). - - * If a zero-length extent has the `end-open' property but not the - `start-open' property (this is the default), text inserted at the - extent's location causes the extent to move forward, just like a - marker. - - * If a zero-length extent has the `start-open' property but not the - `end-open' property, text inserted at the extent's location causes - the extent to remain before the text, like what happens to markers - when `insert-before-markers' is used. - - * Markers end up after or before inserted text depending on whether - `insert' or `insert-before-markers' was called. These functions - do not affect zero-length extents differently; instead, the - presence or absence of the `start-open' and `end-open' extent - properties determines this, as just described. - - * Markers are automatically removed from a buffer when they are no - longer in use. Extents remain around until explicitly removed - from a buffer. - - * Many functions are provided for listing the extents in a buffer or - in a region of a buffer.

The text that +remains addressable is called the "accessible portion" of the buffer. + + Narrowing is specified with two buffer positions which become the +beginning and end of the accessible portion. For most editing commands +and most Emacs primitives, these positions replace the values of the +beginning and end of the buffer. While narrowing is in effect, no text +outside the accessible portion is displayed, and point cannot move +outside the accessible portion. + + Values such as positions or line numbers, which usually count from +the beginning of the buffer, do so despite narrowing, but the functions +which use them refuse to operate on text that is inaccessible. + + The commands for saving buffers are unaffected by narrowing; they +save the entire buffer regardless of any narrowing. + + - Command: narrow-to-region start end &optional buffer + This function sets the accessible portion of BUFFER to start at + START and end at END. Both arguments should be character + positions. BUFFER defaults to the current buffer if omitted. + + In an interactive call, START and END are set to the bounds of the + current region (point and the mark, with the smallest first). + + - Command: narrow-to-page &optional move-count + This function sets the accessible portion of the current buffer to + include just the current page. An optional first argument + MOVE-COUNT non-`nil' means to move forward or backward by + MOVE-COUNT pages and then narrow. The variable `page-delimiter' + specifies where pages start and end (*note Standard Regexps::). + + In an interactive call, MOVE-COUNT is set to the numeric prefix + argument. + + - Command: widen &optional buffer + This function cancels any narrowing in BUFFER, so that the entire + contents are accessible. This is called "widening". It is + equivalent to the following expression: + + (narrow-to-region 1 (1+ (buffer-size))) + + BUFFER defaults to the current buffer if omitted. + + - Special Form: save-restriction body... + This special form saves the current bounds of the accessible + portion, evaluates the BODY forms, and finally restores the saved + bounds, thus restoring the same state of narrowing (or absence + thereof) formerly in effect. The state of narrowing is restored + even in the event of an abnormal exit via `throw' or error (*note + Nonlocal Exits::). Therefore, this construct is a clean way to + narrow a buffer temporarily. + + The value returned by `save-restriction' is that returned by the + last form in BODY, or `nil' if no body forms were given. + + *Caution:* it is easy to make a mistake when using the + `save-restriction' construct. Read the entire description here + before you try it. + + If BODY changes the current buffer, `save-restriction' still + restores the restrictions on the original buffer (the buffer whose + restrictions it saved from), but it does not restore the identity + of the current buffer. + + `save-restriction' does _not_ restore point and the mark; use + `save-excursion' for that. If you use both `save-restriction' and + `save-excursion' together, `save-excursion' should come first (on + the outside). Otherwise, the old point value would be restored + with temporary narrowing still in effect. If the old point value + were outside the limits of the temporary narrowing, this would + fail to restore it accurately. + + The `save-restriction' special form records the values of the + beginning and end of the accessible portion as distances from the + beginning and end of the buffer. In other words, it records the + amount of inaccessible text before and after the accessible + portion. + + This method yields correct results if BODY does further narrowing. + However, `save-restriction' can become confused if the body widens + and then make changes outside the range of the saved narrowing. + When this is what you want to do, `save-restriction' is not the + right tool for the job. Here is what you must use instead: + + (let ((start (point-min-marker)) + (end (point-max-marker))) + (unwind-protect + (progn BODY) + (save-excursion + (set-buffer (marker-buffer start)) + (narrow-to-region start end)))) + + Here is a simple example of correct use of `save-restriction': + + ---------- Buffer: foo ---------- + This is the contents of foo + This is the contents of foo + This is the contents of foo-!- + ---------- Buffer: foo ---------- + + (save-excursion + (save-restriction + (goto-char 1) + (forward-line 2) + (narrow-to-region 1 (point)) + (goto-char (point-min)) + (replace-string "foo" "bar"))) + + ---------- Buffer: foo ---------- + This is the contents of bar + This is the contents of bar + This is the contents of foo-!- + ---------- Buffer: foo ---------- + + +File: lispref.info, Node: Markers, Next: Text, Prev: Positions, Up: Top + +Markers +******* + + A "marker" is a Lisp object used to specify a position in a buffer +relative to the surrounding text.

The +marker can be used to represent a position in the functions that +require one, just as an integer could be used. *Note Positions::, for +a complete description of positions. + + A marker has two attributes: the marker position, and the marker +buffer. The marker position is an integer that is equivalent (at a +given time) to the marker as a position in that buffer. But the +marker's position value can change often during the life of the marker. +Insertion and deletion of text in the buffer relocate the marker. The +idea is that a marker positioned between two characters remains between +those two characters despite insertion and deletion elsewhere in the +buffer. Relocation changes the integer equivalent of the marker. + + Deleting text around a marker's position leaves the marker between +the characters immediately before and after the deleted text. Inserting +text at the position of a marker normally leaves the marker in front of +the new text--unless it is inserted with `insert-before-markers' (*note +Insertion::). + + Insertion and deletion in a buffer must check all the markers and +relocate them if necessary. This slows processing in a buffer with a +large number of markers. For this reason, it is a good idea to make a +marker point nowhere if you are sure you don't need it any more. +Unreferenced markers are garbage collected eventually, but until then +will continue to use time if they do point somewhere. + + Because it is common to perform arithmetic operations on a marker +position, most of the arithmetic operations (including `+' and `-') +accept markers as arguments. In such cases, the marker stands for its +current position. + + Note that you can use extents to achieve the same functionality, and +more, as markers. (Markers were defined before extents, which is why +they both continue to exist.) A zero-length extent with the +`detachable' property removed is almost identical to a marker. (*Note +Extent Endpoints::, for more information on zero-length extents.) + + In particular: + + * In order to get marker-like behavior in a zero-length extent, the + `detachable' property must be removed (otherwise, the extent will + disappear when text near it is deleted) and exactly one endpoint + must be closed (if both endpoints are closed, the extent will + expand to contain text inserted where it is located). + + * If a zero-length extent has the `end-open' property but not the + `start-open' property (this is the default), text inserted at the + extent's location causes the extent to move forward, just like a + marker. + + * If a zero-length extent has the `start-open' property but not the + `end-open' property, text inserted at the extent's location causes + the extent to remain before the text, like what happens to markers + when `insert-before-markers' is used. + + * Markers end up after or before inserted text depending on whether + `insert' or `insert-before-markers' was called. These functions + do not affect zero-length extents differently; instead, the + presence or absence of the `start-open' and `end-open' extent + properties determines this, as just described. + + * Markers are automatically removed from a buffer when they are no + longer in use. Extents remain around until explicitly removed + from a buffer. + + * Many functions are provided for listing the extents in a buffer or + in a region of a buffer.

The +values returned by these functions are not meaningful. + + - Function: sort-subr reverse nextrecfun endrecfun &optional + startkeyfun endkeyfun + This function is the general text-sorting routine that divides a + buffer into records and sorts them. Most of the commands in this + section use this function. + + To understand how `sort-subr' works, consider the whole accessible + portion of the buffer as being divided into disjoint pieces called + "sort records". The records may or may not be contiguous; they may + not overlap. A portion of each sort record (perhaps all of it) is + designated as the sort key. Sorting rearranges the records in + order by their sort keys. + + Usually, the records are rearranged in order of ascending sort key. + If the first argument to the `sort-subr' function, REVERSE, is + non-`nil', the sort records are rearranged in order of descending + sort key. + + The next four arguments to `sort-subr' are functions that are + called to move point across a sort record. They are called many + times from within `sort-subr'. + + 1. NEXTRECFUN is called with point at the end of a record. This + function moves point to the start of the next record. The + first record is assumed to start at the position of point + when `sort-subr' is called. Therefore, you should usually + move point to the beginning of the buffer before calling + `sort-subr'. + + This function can indicate there are no more sort records by + leaving point at the end of the buffer. + + 2. ENDRECFUN is called with point within a record. It moves + point to the end of the record. + + 3. STARTKEYFUN is called to move point from the start of a + record to the start of the sort key. This argument is + optional; if it is omitted, the whole record is the sort key. + If supplied, the function should either return a non-`nil' + value to be used as the sort key, or return `nil' to indicate + that the sort key is in the buffer starting at point. In the + latter case, ENDKEYFUN is called to find the end of the sort + key. + + 4. ENDKEYFUN is called to move point from the start of the sort + key to the end of the sort key. This argument is optional. + If STARTKEYFUN returns `nil' and this argument is omitted (or + `nil'), then the sort key extends to the end of the record. + There is no need for ENDKEYFUN if STARTKEYFUN returns a + non-`nil' value. + + As an example of `sort-subr', here is the complete function + definition for `sort-lines': + + ;; Note that the first two lines of doc string + ;; are effectively one line when viewed by a user. + (defun sort-lines (reverse start end) + "Sort lines in region alphabetically. + Called from a program, there are three arguments: + REVERSE (non-nil means reverse order), + and START and END (the region to sort)." + (interactive "P\nr") + (save-restriction + (narrow-to-region start end) + (goto-char (point-min)) + (sort-subr reverse + 'forward-line + 'end-of-line))) + + Here `forward-line' moves point to the start of the next record, + and `end-of-line' moves point to the end of record. We do not pass + the arguments STARTKEYFUN and ENDKEYFUN, because the entire record + is used as the sort key. + + The `sort-paragraphs' function is very much the same, except that + its `sort-subr' call looks like this: + + (sort-subr reverse + (function + (lambda () + (skip-chars-forward "\n \t\f"))) + 'forward-paragraph) + + - Command: sort-regexp-fields reverse record-regexp key-regexp start + end + This command sorts the region between START and END alphabetically + as specified by RECORD-REGEXP and KEY-REGEXP. If REVERSE is a + negative integer, then sorting is in reverse order. + + Alphabetical sorting means that two sort keys are compared by + comparing the first characters of each, the second characters of + each, and so on. If a mismatch is found, it means that the sort + keys are unequal; the sort key whose character is less at the + point of first mismatch is the lesser sort key. The individual + characters are compared according to their numerical values. + Since Emacs uses the ASCII character set, the ordering in that set + determines alphabetical order. + + The value of the RECORD-REGEXP argument specifies how to divide + the buffer into sort records. At the end of each record, a search + is done for this regular expression, and the text that matches it + is the next record. For example, the regular expression `^.+$', + which matches lines with at least one character besides a newline, + would make each such line into a sort record. *Note Regular + Expressions::, for a description of the syntax and meaning of + regular expressions. + + The value of the KEY-REGEXP argument specifies what part of each + record is the sort key. The KEY-REGEXP could match the whole + record, or only a part. In the latter case, the rest of the + record has no effect on the sorted order of records, but it is + carried along when the record moves to its new position. + + The KEY-REGEXP argument can refer to the text matched by a + subexpression of RECORD-REGEXP, or it can be a regular expression + on its own. + + If KEY-REGEXP is: + + `\DIGIT' + then the text matched by the DIGITth `\(...\)' parenthesis + grouping in RECORD-REGEXP is the sort key. + + `\&' + then the whole record is the sort key. + + a regular expression + then `sort-regexp-fields' searches for a match for the regular + expression within the record. If such a match is found, it + is the sort key. If there is no match for KEY-REGEXP within + a record then that record is ignored, which means its + position in the buffer is not changed. (The other records + may move around it.) + + For example, if you plan to sort all the lines in the region by the + first word on each line starting with the letter `f', you should + set RECORD-REGEXP to `^.*$' and set KEY-REGEXP to `\'. The + resulting expression looks like this: + + (sort-regexp-fields nil "^.*$" "\\" + (region-beginning) + (region-end)) + + If you call `sort-regexp-fields' interactively, it prompts for + RECORD-REGEXP and KEY-REGEXP in the minibuffer. + + - Command: sort-lines reverse start end + This command alphabetically sorts lines in the region between + START and END.

This means control characters count as occupying 2 or 4 +columns, depending upon the value of `ctl-arrow', and tabs count as +occupying a number of columns that depends on the value of `tab-width' +and on the column where the tab begins. *Note Usual Display::. + + Column number computations ignore the width of the window and the +amount of horizontal scrolling.

If COLUMN is negative, point moves to the + beginning of the line. + + If it is impossible to move to column COLUMN because that is in + the middle of a multicolumn character such as a tab, point moves + to the end of that character. However, if FORCE is non-`nil', and + COLUMN is in the middle of a tab, then `move-to-column' converts + the tab into spaces so that it can move precisely to column + COLUMN. Other multicolumn characters can cause anomalies despite + FORCE, since there is no way to split them. + + The argument FORCE also has an effect if the line isn't long + enough to reach column COLUMN; in that case, unless the value of + FORCE is the special value `coerce', it says to add whitespace at + the end of the line to reach that column. + + If COLUMN is not a non-negative integer, an error is signaled. + + The return value is the column number actually moved to. + + +File: lispref.info, Node: Indentation, Next: Case Changes, Prev: Columns, Up: Text + +Indentation +=========== + + The indentation functions are used to examine, move to, and change +whitespace that is at the beginning of a line.

You should design the function so + that it will produce the same results as indenting the lines of the + region one by one, but presumably faster. + + If the value is `nil', there is no short cut, and `indent-region' + actually works line by line. + + A short-cut function is useful in modes such as C mode and Lisp + mode, where the `indent-line-function' must scan from the + beginning of the function definition: applying it to each line + would be quadratic in time. The short cut can update the scan + information as it moves through the lines indenting them; this + takes linear time.

The next indent point is the first one at a column + greater than the current column of point. For example, if point + is underneath and to the left of the first non-blank character of + a line of text, it moves to that column by inserting whitespace. + + If the previous nonblank line has no next indent point (i.e., none + at a great enough column position), `indent-relative' either does + nothing (if UNINDENTED-OK is non-`nil') or calls + `tab-to-tab-stop'.

You might also read the manuals to *Note (gawk)Top::, *Note -(ed)Top::, `sed', `grep', *Note (perl)Top::, *Note (regex)Top::, *Note -(rx)Top::, `pcre', and *Note (flex)Top::, which also make good use of -regular expressions. - - The XEmacs regular expression syntax most closely resembles that of -`ed', or `grep', the GNU versions of which all utilize the GNU `regex' -library. XEmacs' version of `regex' has recently been extended with -some Perl-like capabilities, described in the next section. - -* Menu: - -* Syntax of Regexps:: Rules for writing regular expressions. -* Regexp Example:: Illustrates regular expression syntax. - - -File: lispref.info, Node: Syntax of Regexps, Next: Regexp Example, Up: Regular Expressions - -Syntax of Regular Expressions ------------------------------ - - Regular expressions have a syntax in which a few characters are -special constructs and the rest are "ordinary". An ordinary character -is a simple regular expression that matches that character and nothing -else. The special characters are `.', `*', `+', `?', `[', `]', `^', -`$', and `\'; no new special characters will be defined in the future. -Any other character appearing in a regular expression is ordinary, -unless a `\' precedes it. - - For example, `f' is not a special character, so it is ordinary, and -therefore `f' is a regular expression that matches the string `f' and -no other string. (It does _not_ match the string `ff'.) Likewise, `o' -is a regular expression that matches only `o'. - - Any two regular expressions A and B can be concatenated. The result -is a regular expression that matches a string if A matches some amount -of the beginning of that string and B matches the rest of the string. - - As a simple example, we can concatenate the regular expressions `f' -and `o' to get the regular expression `fo', which matches only the -string `fo'. Still trivial. To do something more powerful, you need -to use one of the special characters. Here is a list of them: - -`. (Period)' - is a special character that matches any single character except a - newline. Using concatenation, we can make regular expressions - like `a.b', which matches any three-character string that begins - with `a' and ends with `b'. - -`*' - is not a construct by itself; it is a quantifying suffix operator - that means to repeat the preceding regular expression as many - times as possible. In `fo*', the `*' applies to the `o', so `fo*' - matches one `f' followed by any number of `o's. The case of zero - `o's is allowed: `fo*' does match `f'. - - `*' always applies to the _smallest_ possible preceding - expression. Thus, `fo*' has a repeating `o', not a repeating `fo'. - - The matcher processes a `*' construct by matching, immediately, as - many repetitions as can be found; it is "greedy". Then it - continues with the rest of the pattern. If that fails, - backtracking occurs, discarding some of the matches of the - `*'-modified construct in case that makes it possible to match the - rest of the pattern. For example, in matching `ca*ar' against the - string `caaar', the `a*' first tries to match all three `a's; but - the rest of the pattern is `ar' and there is only `r' left to - match, so this try fails. The next alternative is for `a*' to - match only two `a's. With this choice, the rest of the regexp - matches successfully. - - Nested repetition operators can be extremely slow if they specify - backtracking loops. For example, it could take hours for the - regular expression `\(x+y*\)*a' to match the sequence - `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxz'. The slowness is because - Emacs must try each imaginable way of grouping the 35 `x''s before - concluding that none of them can work. To make sure your regular - expressions run fast, check nested repetitions carefully. - -`+' - is a quantifying suffix operator similar to `*' except that the - preceding expression must match at least once. It is also - "greedy". So, for example, `ca+r' matches the strings `car' and - `caaaar' but not the string `cr', whereas `ca*r' matches all three - strings. - -`?' - is a quantifying suffix operator similar to `*', except that the - preceding expression can match either once or not at all. For - example, `ca?r' matches `car' or `cr', but does not match anything - else. - -`*?' - works just like `*', except that rather than matching the longest - match, it matches the shortest match. `*?' is known as a - "non-greedy" quantifier, a regexp construct borrowed from Perl. - - This construct is very useful for when you want to match the text - inside a pair of delimiters. For instance, `/\*.*?\*/' will match - C comments in a string. This could not easily be achieved without - the use of a non-greedy quantifier. - - This construct has not been available prior to XEmacs 20.4. It is - not available in FSF Emacs. - -`+?' - is the non-greedy version of `+'. - -`??' - is the non-greedy version of `?'. - -`\{n,m\}' - serves as an interval quantifier, analogous to `*' or `+', but - specifies that the expression must match at least N times, but no - more than M times. This syntax is supported by most Unix regexp - utilities, and has been introduced to XEmacs for the version 20.3. - - Unfortunately, the non-greedy version of this quantifier does not - exist currently, although it does in Perl. - -`[ ... ]' - `[' begins a "character set", which is terminated by a `]'. In - the simplest case, the characters between the two brackets form - the set. Thus, `[ad]' matches either one `a' or one `d', and - `[ad]*' matches any string composed of just `a's and `d's - (including the empty string), from which it follows that `c[ad]*r' - matches `cr', `car', `cdr', `caddaar', etc. - - The usual regular expression special characters are not special - inside a character set. A completely different set of special - characters exists inside character sets: `]', `-' and `^'. - - `-' is used for ranges of characters. To write a range, write two - characters with a `-' between them. Thus, `[a-z]' matches any - lower case letter. Ranges may be intermixed freely with individual - characters, as in `[a-z$%.]', which matches any lower case letter - or `$', `%', or a period. - - To include a `]' in a character set, make it the first character. - For example, `[]a]' matches `]' or `a'. To include a `-', write - `-' as the first character in the set, or put it immediately after - a range. (You can replace one individual character C with the - range `C-C' to make a place to put the `-'.) There is no way to - write a set containing just `-' and `]'. - - To include `^' in a set, put it anywhere but at the beginning of - the set. - -`[^ ... ]' - `[^' begins a "complement character set", which matches any - character except the ones specified. Thus, `[^a-z0-9A-Z]' matches - all characters _except_ letters and digits. - - `^' is not special in a character set unless it is the first - character. The character following the `^' is treated as if it - were first (thus, `-' and `]' are not special there). - - Note that a complement character set can match a newline, unless - newline is mentioned as one of the characters not to match. - -`^' - is a special character that matches the empty string, but only at - the beginning of a line in the text being matched. Otherwise it - fails to match anything. Thus, `^foo' matches a `foo' that occurs - at the beginning of a line. - - When matching a string instead of a buffer, `^' matches at the - beginning of the string or after a newline character `\n'. - -`$' - is similar to `^' but matches only at the end of a line. Thus, - `x+$' matches a string of one `x' or more at the end of a line. - - When matching a string instead of a buffer, `$' matches at the end - of the string or before a newline character `\n'. - -`\' - has two functions: it quotes the special characters (including - `\'), and it introduces additional special constructs. - - Because `\' quotes special characters, `\$' is a regular - expression that matches only `$', and `\[' is a regular expression - that matches only `[', and so on. - - Note that `\' also has special meaning in the read syntax of Lisp - strings (*note String Type::), and must be quoted with `\'. For - example, the regular expression that matches the `\' character is - `\\'. To write a Lisp string that contains the characters `\\', - Lisp syntax requires you to quote each `\' with another `\'. - Therefore, the read syntax for a regular expression matching `\' - is `"\\\\"'. - - *Please note:* For historical compatibility, special characters are -treated as ordinary ones if they are in contexts where their special -meanings make no sense. For example, `*foo' treats `*' as ordinary -since there is no preceding expression on which the `*' can act. It is -poor practice to depend on this behavior; quote the special character -anyway, regardless of where it appears. - - For the most part, `\' followed by any character matches only that -character. However, there are several exceptions: characters that, -when preceded by `\', are special constructs. Such characters are -always ordinary when encountered on their own. Here is a table of `\' -constructs: - -`\|' - specifies an alternative. Two regular expressions A and B with - `\|' in between form an expression that matches anything that - either A or B matches. - - Thus, `foo\|bar' matches either `foo' or `bar' but no other string. - - `\|' applies to the largest possible surrounding expressions. - Only a surrounding `\( ... \)' grouping can limit the grouping - power of `\|'. - - Full backtracking capability exists to handle multiple uses of - `\|'. - -`\( ... \)' - is a grouping construct that serves three purposes: - - 1. To enclose a set of `\|' alternatives for other operations. - Thus, `\(foo\|bar\)x' matches either `foox' or `barx'. - - 2. To enclose an expression for a suffix operator such as `*' to - act on. Thus, `ba\(na\)*' matches `bananana', etc., with any - (zero or more) number of `na' strings. - - 3. To record a matched substring for future reference. - - This last application is not a consequence of the idea of a - parenthetical grouping; it is a separate feature that happens to be - assigned as a second meaning to the same `\( ... \)' construct - because there is no conflict in practice between the two meanings. - Here is an explanation of this feature: - -`\DIGIT' - matches the same text that matched the DIGITth occurrence of a `\( - ... \)' construct. - - In other words, after the end of a `\( ... \)' construct. the - matcher remembers the beginning and end of the text matched by that - construct. Then, later on in the regular expression, you can use - `\' followed by DIGIT to match that same text, whatever it may - have been. - - The strings matching the first nine `\( ... \)' constructs - appearing in a regular expression are assigned numbers 1 through 9 - in the order that the open parentheses appear in the regular - expression. So you can use `\1' through `\9' to refer to the text - matched by the corresponding `\( ... \)' constructs. - - For example, `\(.*\)\1' matches any newline-free string that is - composed of two identical halves. The `\(.*\)' matches the first - half, which may be anything, but the `\1' that follows must match - the same exact text. - -`\(?: ... \)' - is called a "shy" grouping operator, and it is used just like `\( - ... \)', except that it does not cause the matched substring to be - recorded for future reference. - - This is useful when you need a lot of grouping `\( ... \)' - constructs, but only want to remember one or two - or if you have - more than nine groupings and need to use backreferences to refer to - the groupings at the end. - - Using `\(?: ... \)' rather than `\( ... \)' when you don't need - the captured substrings ought to speed up your programs some, - since it shortens the code path followed by the regular expression - engine, as well as the amount of memory allocation and string - copying it must do. The actual performance gain to be observed - has not been measured or quantified as of this writing. - - The shy grouping operator has been borrowed from Perl, and has not - been available prior to XEmacs 20.3, nor is it available in FSF - Emacs. - -`\w' - matches any word-constituent character. The editor syntax table - determines which characters these are. *Note Syntax Tables::. - -`\W' - matches any character that is not a word constituent. - -`\sCODE' - matches any character whose syntax is CODE. Here CODE is a - character that represents a syntax code: thus, `w' for word - constituent, `-' for whitespace, `(' for open parenthesis, etc. - *Note Syntax Tables::, for a list of syntax codes and the - characters that stand for them. - -`\SCODE' - matches any character whose syntax is not CODE. - - The following regular expression constructs match the empty -string--that is, they don't use up any characters--but whether they -match depends on the context. - -`\`' - matches the empty string, but only at the beginning of the buffer - or string being matched against. - -`\'' - matches the empty string, but only at the end of the buffer or - string being matched against. - -`\=' - matches the empty string, but only at point. (This construct is - not defined when matching against a string.) - -`\b' - matches the empty string, but only at the beginning or end of a - word. Thus, `\bfoo\b' matches any occurrence of `foo' as a - separate word. `\bballs?\b' matches `ball' or `balls' as a - separate word. - -`\B' - matches the empty string, but _not_ at the beginning or end of a - word. - -`\<' - matches the empty string, but only at the beginning of a word. - -`\>' - matches the empty string, but only at the end of a word. - - Not every string is a valid regular expression. For example, a -string with unbalanced square brackets is invalid (with a few -exceptions, such as `[]]'), and so is a string that ends with a single -`\'. If an invalid regular expression is passed to any of the search -functions, an `invalid-regexp' error is signaled. - - - Function: regexp-quote string - This function returns a regular expression string that matches - exactly STRING and nothing else.

Such operations +can, of course, be implemented in Emacs Lisp, but tend to be very slow +for large portions of text or data. This is why some of them are +implemented in C, with an appropriate interface for Lisp programmers. +Examples of algorithms thus provided are MD5 and base64 support. + + MD5 is an algorithm for calculating message digests, as described in +rfc1321. Given a message of arbitrary length, MD5 produces an 128-bit +"fingerprint" ("message digest") corresponding to that message. It is +considered computationally infeasible to produce two messages having +the same MD5 digest, or to produce a message having a prespecified +target digest. MD5 is used heavily by various authentication schemes. + + Emacs Lisp interface to MD5 consists of a single function `md5': + + - Function: md5 object &optional start end coding noerror + This function returns the MD5 message digest of OBJECT, a buffer + or string. + + Optional arguments START and END denote positions for computing + the digest of a portion of OBJECT. + + The optional CODING argument specifies the coding system the text + is to be represented in while computing the digest. If + unspecified, it defaults to the current format of the data, or is + guessed. + + If NOERROR is non-`nil', silently assume binary coding if the + guesswork fails. Normally, an error is signaled in such case. + + CODING and NOERROR arguments are meaningful only in XEmacsen with + file-coding or Mule support. Otherwise, they are ignored. Some + examples of usage: + + ;; Calculate the digest of the entire buffer + (md5 (current-buffer)) + => "8842b04362899b1cda8d2d126dc11712" + + ;; Calculate the digest of the current line + (md5 (current-buffer) (point-at-bol) (point-at-eol)) + => "60614d21e9dee27dfdb01fa4e30d6d00" + + ;; Calculate the digest of your name and email address + (md5 (concat (format "%s <%s>" (user-full-name) user-mail-address))) + => "0a2188c40fd38922d941fe6032fce516" + + Base64 is a portable encoding for arbitrary sequences of octets, in a +form that need not be readable by humans. It uses a 65-character subset +of US-ASCII, as described in rfc2045. Base64 is used by MIME to encode +binary bodies, and to encode binary characters in message headers. + + The Lisp interface to base64 consists of four functions: + + - Command: base64-encode-region start end &optional no-line-break + This function encodes the region between START and END of the + current buffer to base64 format. This means that the original + region is deleted, and replaced with its base64 equivalent. + + Normally, encoded base64 output is multi-line, with 76-character + lines. If NO-LINE-BREAK is non-`nil', newlines will not be + inserted, resulting in single-line output. + + Mule note: you should make sure that you convert the multibyte + characters (those that do not fit into 0-255 range) to something + else, because they cannot be meaningfully converted to base64. If + the `base64-encode-region' encounters such characters, it will + signal an error. + + `base64-encode-region' returns the length of the encoded text. + + ;; Encode the whole buffer in base64 + (base64-encode-region (point-min) (point-max)) + + The function can also be used interactively, in which case it + works on the currently active region. + + - Function: base64-encode-string string &optional no-line-break + This function encodes STRING to base64, and returns the encoded + string. + + Normally, encoded base64 output is multi-line, with 76-character + lines. If NO-LINE-BREAK is non-`nil', newlines will not be + inserted, resulting in single-line output. + + For Mule, the same considerations apply as for + `base64-encode-region'. + + (base64-encode-string "fubar") + => "ZnViYXI=" + + - Command: base64-decode-region start end + This function decodes the region between START and END of the + current buffer.

(It + must be a position in the current buffer.) No match extending + after that position is accepted. If LIMIT is omitted or `nil', it + defaults to the end of the accessible portion of the buffer. + + What happens when the search fails depends on the value of + NOERROR. If NOERROR is `nil', a `search-failed' error is + signaled. If NOERROR is `t', `search-forward' returns `nil' and + does nothing. If NOERROR is neither `nil' nor `t', then + `search-forward' moves point to the upper bound and returns `nil'. + (It would be more consistent now to return the new position of + point in that case, but some programs may depend on a value of + `nil'.) + + If COUNT is supplied (it must be an integer), then the search is + repeated that many times (each time starting at the end of the + previous time's match).

Searching for matches for +a regexp is a very powerful operation. This section explains how to +write regexps; the following section says how to search for them. + + To gain a thorough understanding of regular expressions and how to +use them to best advantage, we recommend that you study `Mastering +Regular Expressions, by Jeffrey E.F. Friedl, O'Reilly and Associates, +1997'. (It's known as the "Hip Owls" book, because of the picture on its +cover.) You might also read the manuals to *Note (gawk)Top::, *Note +(ed)Top::, `sed', `grep', *Note (perl)Top::, *Note (regex)Top::, *Note +(rx)Top::, `pcre', and *Note (flex)Top::, which also make good use of +regular expressions. + + The XEmacs regular expression syntax most closely resembles that of +`ed', or `grep', the GNU versions of which all utilize the GNU `regex' +library. XEmacs' version of `regex' has recently been extended with +some Perl-like capabilities, described in the next section. + +* Menu: + +* Syntax of Regexps:: Rules for writing regular expressions. +* Regexp Example:: Illustrates regular expression syntax. + + +File: lispref.info, Node: Syntax of Regexps, Next: Regexp Example, Up: Regular Expressions + +Syntax of Regular Expressions +----------------------------- + + Regular expressions have a syntax in which a few characters are +special constructs and the rest are "ordinary". An ordinary character +is a simple regular expression that matches that character and nothing +else. The special characters are `.', `*', `+', `?', `[', `]', `^', +`$', and `\'; no new special characters will be defined in the future. +Any other character appearing in a regular expression is ordinary, +unless a `\' precedes it. + + For example, `f' is not a special character, so it is ordinary, and +therefore `f' is a regular expression that matches the string `f' and +no other string. (It does _not_ match the string `ff'.) Likewise, `o' +is a regular expression that matches only `o'. + + Any two regular expressions A and B can be concatenated. The result +is a regular expression that matches a string if A matches some amount +of the beginning of that string and B matches the rest of the string. + + As a simple example, we can concatenate the regular expressions `f' +and `o' to get the regular expression `fo', which matches only the +string `fo'. Still trivial. To do something more powerful, you need +to use one of the special characters. Here is a list of them: + +`. (Period)' + is a special character that matches any single character except a + newline. Using concatenation, we can make regular expressions + like `a.b', which matches any three-character string that begins + with `a' and ends with `b'. + +`*' + is not a construct by itself; it is a quantifying suffix operator + that means to repeat the preceding regular expression as many + times as possible. In `fo*', the `*' applies to the `o', so `fo*' + matches one `f' followed by any number of `o's. The case of zero + `o's is allowed: `fo*' does match `f'. + + `*' always applies to the _smallest_ possible preceding + expression. Thus, `fo*' has a repeating `o', not a repeating `fo'. + + The matcher processes a `*' construct by matching, immediately, as + many repetitions as can be found; it is "greedy". Then it + continues with the rest of the pattern. If that fails, + backtracking occurs, discarding some of the matches of the + `*'-modified construct in case that makes it possible to match the + rest of the pattern. For example, in matching `ca*ar' against the + string `caaar', the `a*' first tries to match all three `a's; but + the rest of the pattern is `ar' and there is only `r' left to + match, so this try fails. The next alternative is for `a*' to + match only two `a's. With this choice, the rest of the regexp + matches successfully. + + Nested repetition operators can be extremely slow if they specify + backtracking loops. For example, it could take hours for the + regular expression `\(x+y*\)*a' to match the sequence + `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxz'. The slowness is because + Emacs must try each imaginable way of grouping the 35 `x''s before + concluding that none of them can work. To make sure your regular + expressions run fast, check nested repetitions carefully. + +`+' + is a quantifying suffix operator similar to `*' except that the + preceding expression must match at least once. It is also + "greedy". So, for example, `ca+r' matches the strings `car' and + `caaaar' but not the string `cr', whereas `ca*r' matches all three + strings. + +`?' + is a quantifying suffix operator similar to `*', except that the + preceding expression can match either once or not at all. For + example, `ca?r' matches `car' or `cr', but does not match anything + else. + +`*?' + works just like `*', except that rather than matching the longest + match, it matches the shortest match. `*?' is known as a + "non-greedy" quantifier, a regexp construct borrowed from Perl. + + This construct is very useful for when you want to match the text + inside a pair of delimiters. For instance, `/\*.*?\*/' will match + C comments in a string. This could not easily be achieved without + the use of a non-greedy quantifier. + + This construct has not been available prior to XEmacs 20.4. It is + not available in FSF Emacs. + +`+?' + is the non-greedy version of `+'. + +`??' + is the non-greedy version of `?'. + +`\{n,m\}' + serves as an interval quantifier, analogous to `*' or `+', but + specifies that the expression must match at least N times, but no + more than M times. This syntax is supported by most Unix regexp + utilities, and has been introduced to XEmacs for the version 20.3. + + Unfortunately, the non-greedy version of this quantifier does not + exist currently, although it does in Perl. + +`[ ... ]' + `[' begins a "character set", which is terminated by a `]'. In + the simplest case, the characters between the two brackets form + the set. Thus, `[ad]' matches either one `a' or one `d', and + `[ad]*' matches any string composed of just `a's and `d's + (including the empty string), from which it follows that `c[ad]*r' + matches `cr', `car', `cdr', `caddaar', etc. + + The usual regular expression special characters are not special + inside a character set. A completely different set of special + characters exists inside character sets: `]', `-' and `^'. + + `-' is used for ranges of characters. To write a range, write two + characters with a `-' between them. Thus, `[a-z]' matches any + lower case letter. Ranges may be intermixed freely with individual + characters, as in `[a-z$%.]', which matches any lower case letter + or `$', `%', or a period. + + To include a `]' in a character set, make it the first character. + For example, `[]a]' matches `]' or `a'. To include a `-', write + `-' as the first character in the set, or put it immediately after + a range. (You can replace one individual character C with the + range `C-C' to make a place to put the `-'.) There is no way to + write a set containing just `-' and `]'. + + To include `^' in a set, put it anywhere but at the beginning of + the set. + +`[^ ... ]' + `[^' begins a "complement character set", which matches any + character except the ones specified. Thus, `[^a-z0-9A-Z]' matches + all characters _except_ letters and digits. + + `^' is not special in a character set unless it is the first + character. The character following the `^' is treated as if it + were first (thus, `-' and `]' are not special there). + + Note that a complement character set can match a newline, unless + newline is mentioned as one of the characters not to match. + +`^' + is a special character that matches the empty string, but only at + the beginning of a line in the text being matched. Otherwise it + fails to match anything. Thus, `^foo' matches a `foo' that occurs + at the beginning of a line. + + When matching a string instead of a buffer, `^' matches at the + beginning of the string or after a newline character `\n'. + +`$' + is similar to `^' but matches only at the end of a line. Thus, + `x+$' matches a string of one `x' or more at the end of a line. + + When matching a string instead of a buffer, `$' matches at the end + of the string or before a newline character `\n'. + +`\' + has two functions: it quotes the special characters (including + `\'), and it introduces additional special constructs. + + Because `\' quotes special characters, `\$' is a regular + expression that matches only `$', and `\[' is a regular expression + that matches only `[', and so on. + + Note that `\' also has special meaning in the read syntax of Lisp + strings (*note String Type::), and must be quoted with `\'. For + example, the regular expression that matches the `\' character is + `\\'. To write a Lisp string that contains the characters `\\', + Lisp syntax requires you to quote each `\' with another `\'. + Therefore, the read syntax for a regular expression matching `\' + is `"\\\\"'. + + *Please note:* For historical compatibility, special characters are +treated as ordinary ones if they are in contexts where their special +meanings make no sense. For example, `*foo' treats `*' as ordinary +since there is no preceding expression on which the `*' can act. It is +poor practice to depend on this behavior; quote the special character +anyway, regardless of where it appears. + + For the most part, `\' followed by any character matches only that +character. However, there are several exceptions: characters that, +when preceded by `\', are special constructs. Such characters are +always ordinary when encountered on their own. Here is a table of `\' +constructs: + +`\|' + specifies an alternative. Two regular expressions A and B with + `\|' in between form an expression that matches anything that + either A or B matches. + + Thus, `foo\|bar' matches either `foo' or `bar' but no other string. + + `\|' applies to the largest possible surrounding expressions. + Only a surrounding `\( ... \)' grouping can limit the grouping + power of `\|'. + + Full backtracking capability exists to handle multiple uses of + `\|'. + +`\( ... \)' + is a grouping construct that serves three purposes: + + 1. To enclose a set of `\|' alternatives for other operations. + Thus, `\(foo\|bar\)x' matches either `foox' or `barx'. + + 2. To enclose an expression for a suffix operator such as `*' to + act on. Thus, `ba\(na\)*' matches `bananana', etc., with any + (zero or more) number of `na' strings. + + 3. To record a matched substring for future reference. + + This last application is not a consequence of the idea of a + parenthetical grouping; it is a separate feature that happens to be + assigned as a second meaning to the same `\( ... \)' construct + because there is no conflict in practice between the two meanings. + Here is an explanation of this feature: + +`\DIGIT' + matches the same text that matched the DIGITth occurrence of a `\( + ... \)' construct. + + In other words, after the end of a `\( ... \)' construct. the + matcher remembers the beginning and end of the text matched by that + construct. Then, later on in the regular expression, you can use + `\' followed by DIGIT to match that same text, whatever it may + have been. + + The strings matching the first nine `\( ... \)' constructs + appearing in a regular expression are assigned numbers 1 through 9 + in the order that the open parentheses appear in the regular + expression. So you can use `\1' through `\9' to refer to the text + matched by the corresponding `\( ... \)' constructs. + + For example, `\(.*\)\1' matches any newline-free string that is + composed of two identical halves. The `\(.*\)' matches the first + half, which may be anything, but the `\1' that follows must match + the same exact text. + +`\(?: ... \)' + is called a "shy" grouping operator, and it is used just like `\( + ... \)', except that it does not cause the matched substring to be + recorded for future reference. + + This is useful when you need a lot of grouping `\( ... \)' + constructs, but only want to remember one or two - or if you have + more than nine groupings and need to use backreferences to refer to + the groupings at the end. + + Using `\(?: ... \)' rather than `\( ... \)' when you don't need + the captured substrings ought to speed up your programs some, + since it shortens the code path followed by the regular expression + engine, as well as the amount of memory allocation and string + copying it must do. The actual performance gain to be observed + has not been measured or quantified as of this writing. + + The shy grouping operator has been borrowed from Perl, and has not + been available prior to XEmacs 20.3, nor is it available in FSF + Emacs. + +`\w' + matches any word-constituent character. The editor syntax table + determines which characters these are. *Note Syntax Tables::. + +`\W' + matches any character that is not a word constituent. + +`\sCODE' + matches any character whose syntax is CODE. Here CODE is a + character that represents a syntax code: thus, `w' for word + constituent, `-' for whitespace, `(' for open parenthesis, etc. + *Note Syntax Tables::, for a list of syntax codes and the + characters that stand for them. + +`\SCODE' + matches any character whose syntax is not CODE. + + The following regular expression constructs match the empty +string--that is, they don't use up any characters--but whether they +match depends on the context. + +`\`' + matches the empty string, but only at the beginning of the buffer + or string being matched against. + +`\'' + matches the empty string, but only at the end of the buffer or + string being matched against. + +`\=' + matches the empty string, but only at point. (This construct is + not defined when matching against a string.) + +`\b' + matches the empty string, but only at the beginning or end of a + word. Thus, `\bfoo\b' matches any occurrence of `foo' as a + separate word. `\bballs?\b' matches `ball' or `balls' as a + separate word. + +`\B' + matches the empty string, but _not_ at the beginning or end of a + word. + +`\<' + matches the empty string, but only at the beginning of a word. + +`\>' + matches the empty string, but only at the end of a word. + + Not every string is a valid regular expression.

Most often, the paragraph commands do check for a -match only at the beginning of a line, which means that `^' would be -superfluous. When there is a nonzero left margin, they accept matches -that start after the left margin. In that case, a `^' would be -incorrect. However, a `^' is harmless in modes where a left margin is -never used. - - - Variable: paragraph-separate - This is the regular expression for recognizing the beginning of a - line that separates paragraphs. (If you change this, you may have - to change `paragraph-start' also.) The default value is - `"[ \t\f]*$"', which matches a line that consists entirely of - spaces, tabs, and form feeds (after its left margin). - - - Variable: paragraph-start - This is the regular expression for recognizing the beginning of a - line that starts _or_ separates paragraphs. The default value is - `"[ \t\n\f]"', which matches a line starting with a space, tab, - newline, or form feed (after its left margin). - - - Variable: sentence-end - This is the regular expression describing the end of a sentence. - (All paragraph boundaries also end sentences, regardless.)

This information is -used by the parsing commands, the complex movement commands, and others -to determine where words, symbols, and other syntactic constructs begin -and end. The current syntax table controls the meaning of the word -motion functions (*note Word Motion::) and the list motion functions -(*note List Motion::) as well as the functions in this chapter. - - Under XEmacs 20, a syntax table is a particular subtype of the -primitive char table type (*note Char Tables::), and each element of the -char table is an integer that encodes the syntax of the character in -question, or a cons of such an integer and a matching character (for -characters with parenthesis syntax). - - Under XEmacs 19, a syntax table is a vector of 256 elements; it -contains one entry for each of the 256 possible characters in an 8-bit -byte. Each element is an integer that encodes the syntax of the -character in question. (The matching character, if any, is embedded in -the bits of this integer.) - - Syntax tables are used only for moving across text, not for the Emacs -Lisp reader. XEmacs Lisp uses built-in syntactic rules when reading -Lisp expressions, and these rules cannot be changed. - - Each buffer has its own major mode, and each major mode has its own -idea of the syntactic class of various characters. For example, in Lisp -mode, the character `;' begins a comment, but in C mode, it terminates -a statement. To support these variations, XEmacs makes the choice of -syntax table local to each buffer. Typically, each major mode has its -own syntax table and installs that table in each buffer that uses that -mode. Changing this table alters the syntax in all those buffers as -well as in any buffers subsequently put in that mode. Occasionally -several similar modes share one syntax table. *Note Example Major -Modes::, for an example of how to set up a syntax table. - - A syntax table can inherit the data for some characters from the -standard syntax table, while specifying other characters itself. The -"inherit" syntax class means "inherit this character's syntax from the -standard syntax table." Most major modes' syntax tables inherit the -syntax of character codes 0 through 31 and 128 through 255. This is -useful with character sets such as ISO Latin-1 that have additional -alphabetic characters in the range 128 to 255. Just changing the -standard syntax for these characters affects all major modes. - - - Function: syntax-table-p object - This function returns `t' if OBJECT is a vector of length 256 - elements. This means that the vector may be a syntax table. - However, according to this test, any vector of length 256 is - considered to be a syntax table, no matter what its contents. - - -File: lispref.info, Node: Syntax Descriptors, Next: Syntax Table Functions, Prev: Syntax Basics, Up: Syntax Tables - -Syntax Descriptors -================== - - This section describes the syntax classes and flags that denote the -syntax of a character, and how they are represented as a "syntax -descriptor", which is a Lisp string that you pass to -`modify-syntax-entry' to specify the desired syntax. - - XEmacs defines a number of "syntax classes". Each syntax table puts -each character into one class. There is no necessary relationship -between the class of a character in one syntax table and its class in -any other table. - - Each class is designated by a mnemonic character, which serves as the -name of the class when you need to specify a class. Usually the -designator character is one that is frequently in that class; however, -its meaning as a designator is unvarying and independent of what syntax -that character currently has. - - A syntax descriptor is a Lisp string that specifies a syntax class, a -matching character (used only for the parenthesis classes) and flags. -The first character is the designator for a syntax class. The second -character is the character to match; if it is unused, put a space there. -Then come the characters for any desired flags. If no matching -character or flags are needed, one character is sufficient. - - For example, the descriptor for the character `*' in C mode is -`. 23' (i.e., punctuation, matching character slot unused, second -character of a comment-starter, first character of an comment-ender), -and the entry for `/' is `. 14' (i.e., punctuation, matching character -slot unused, first character of a comment-starter, second character of -a comment-ender). - -* Menu: - -* Syntax Class Table:: Table of syntax classes. -* Syntax Flags:: Additional flags each character can have. - - -File: lispref.info, Node: Syntax Class Table, Next: Syntax Flags, Up: Syntax Descriptors - -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 - "Whitespace characters" (designated with ` ' or `-') separate - symbols and words from each other. Typically, whitespace - characters have no other syntactic significance, and multiple - whitespace characters are syntactically equivalent to a single - one. Space, tab, newline and formfeed are almost always - classified as whitespace. - - - 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 - "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 - used in Lisp mode to indicate that certain characters may be part - of symbol names even though they are not part of English words. - These characters are `$&*+-_<>'. In standard C, the only - non-word-constituent character that is valid in symbols is - underscore (`_'). - - - 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 - language modes, including Emacs Lisp mode, have no characters in - 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 - 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 - terminated with a close. Each open parenthesis character matches - a particular close parenthesis character, and vice versa. - Normally, XEmacs indicates momentarily the matching open - parenthesis when you insert a close parenthesis. *Note Blinking::. - - The class of open parentheses is designated with `(', and that of - close parentheses with `)'. - - In English text, and in C code, the parenthesis pairs are `()', - `[]', and `{}'. In XEmacs Lisp, the delimiters for lists and - vectors (`()' and `[]') are classified as parenthesis characters. - - - 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 - of a string. Such quoted strings do not nest. - - The parsing facilities of XEmacs consider a string as a single - token. The usual syntactic meanings of the characters in the - string are suppressed. - - The Lisp modes have two string quote characters: double-quote (`"') - and vertical bar (`|'). `|' is not used in XEmacs Lisp, but it is - used in Common Lisp. C also has two string quote characters: - double-quote for strings, and single-quote (`'') for character - constants. - - English text has no string quote characters because English is not - a programming language. Although quotation marks are used in - 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 - is used thus only inside strings, but it turns out to cause no - trouble to treat it this way throughout C code.) - - Characters in this class count as part of words if - `words-include-escapes' is non-`nil'. *Note Word Motion::. - - - Syntax class: character quote - 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 - immediately following is ever affected. - - Characters in this class count as part of words if - `words-include-escapes' is non-`nil'. *Note Word Motion::. - - This class is used for backslash in TeX mode. - - - 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 - 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 - 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 - 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 `@'. - - -File: lispref.info, Node: Syntax Flags, Prev: Syntax Class Table, Up: Syntax Descriptors - -Syntax Flags ------------- - - In addition to the classes, entries for characters in a syntax table -can include flags. There are six possible flags, represented by the -characters `1', `2', `3', `4', `b' and `p'. - - All the flags except `p' are used to describe multi-character -comment delimiters. The digit flags indicate that a character can -_also_ be part of a comment sequence, in addition to the syntactic -properties associated with its character class. The flags are -independent of the class and each other for the sake of characters such -as `*' in C mode, which is a punctuation character, _and_ the second -character of a start-of-comment sequence (`/*'), _and_ the first -character of an end-of-comment sequence (`*/'). - - The flags for a character C are: - - * `1' means C is the start of a two-character comment-start sequence. - - * `2' means C is the second character of such a sequence. - - * `3' means C is the start of a two-character comment-end sequence. - - * `4' means C is the second character of such a sequence. - - * `b' means that C as a comment delimiter belongs to the alternative - "b" comment style. - - Emacs supports two comment styles simultaneously in any one syntax - table. This is for the sake of C++. Each style of comment syntax - has its own comment-start sequence and its own comment-end - sequence. Each comment must stick to one style or the other; - thus, if it starts with the comment-start sequence of style "b", - it must also end with the comment-end sequence of style "b". - - The two comment-start sequences must begin with the same - character; only the second character may differ. Mark the second - character of the "b"-style comment-start sequence with the `b' - flag. - - A comment-end sequence (one or two characters) applies to the "b" - style if its first character has the `b' flag set; otherwise, it - applies to the "a" style. - - The appropriate comment syntax settings for C++ are as follows: - - `/' - `124b' - - `*' - `23' - - newline - `>b' - - This defines four comment-delimiting sequences: - - `/*' - This is a comment-start sequence for "a" style because the - second character, `*', does not have the `b' flag. - - `//' - This is a comment-start sequence for "b" style because the - second character, `/', does have the `b' flag. - - `*/' - This is a comment-end sequence for "a" style because the first - character, `*', does not have the `b' flag - - newline - This is a comment-end sequence for "b" style, because the - newline character has the `b' flag. - - * `p' identifies an additional "prefix character" for Lisp syntax. - These characters are treated as whitespace when they appear between - expressions. When they appear within an expression, they are - handled according to their usual syntax codes. - - The function `backward-prefix-chars' moves back over these - characters, as well as over characters whose primary syntax class - is prefix (`''). *Note Motion and Syntax::. - - -File: lispref.info, Node: Syntax Table Functions, Next: Motion and Syntax, Prev: Syntax Descriptors, Up: Syntax Tables - -Syntax Table Functions -====================== - - In this section we describe functions for creating, accessing and -altering syntax tables. - - - Function: make-syntax-table &optional table - This function creates a new syntax table.

Alternatively, you +may change the value of `default-case-fold-search', which is the +default value of `case-fold-search' for buffers that do not override it. + + Note that the user-level incremental search feature handles case +distinctions differently.

Most often, the paragraph commands do check for a +match only at the beginning of a line, which means that `^' would be +superfluous. When there is a nonzero left margin, they accept matches +that start after the left margin. In that case, a `^' would be +incorrect. However, a `^' is harmless in modes where a left margin is +never used. + + - Variable: paragraph-separate + This is the regular expression for recognizing the beginning of a + line that separates paragraphs. (If you change this, you may have + to change `paragraph-start' also.)

This information is +used by the parsing commands, the complex movement commands, and others +to determine where words, symbols, and other syntactic constructs begin +and end. The current syntax table controls the meaning of the word +motion functions (*note Word Motion::) and the list motion functions +(*note List Motion::) as well as the functions in this chapter. + + Under XEmacs 20, a syntax table is a particular subtype of the +primitive char table type (*note Char Tables::), and each element of the +char table is an integer that encodes the syntax of the character in +question, or a cons of such an integer and a matching character (for +characters with parenthesis syntax). + + Under XEmacs 19, a syntax table is a vector of 256 elements; it +contains one entry for each of the 256 possible characters in an 8-bit +byte. Each element is an integer that encodes the syntax of the +character in question. (The matching character, if any, is embedded in +the bits of this integer.) + + Syntax tables are used only for moving across text, not for the Emacs +Lisp reader. XEmacs Lisp uses built-in syntactic rules when reading +Lisp expressions, and these rules cannot be changed. + + Each buffer has its own major mode, and each major mode has its own +idea of the syntactic class of various characters. For example, in Lisp +mode, the character `;' begins a comment, but in C mode, it terminates +a statement. To support these variations, XEmacs makes the choice of +syntax table local to each buffer. Typically, each major mode has its +own syntax table and installs that table in each buffer that uses that +mode. Changing this table alters the syntax in all those buffers as +well as in any buffers subsequently put in that mode. Occasionally +several similar modes share one syntax table. *Note Example Major +Modes::, for an example of how to set up a syntax table. + + A syntax table can inherit the data for some characters from the +standard syntax table, while specifying other characters itself. The +"inherit" syntax class means "inherit this character's syntax from the +standard syntax table." Most major modes' syntax tables inherit the +syntax of character codes 0 through 31 and 128 through 255. This is +useful with character sets such as ISO Latin-1 that have additional +alphabetic characters in the range 128 to 255. Just changing the +standard syntax for these characters affects all major modes. + + - Function: syntax-table-p object + This function returns `t' if OBJECT is a vector of length 256 + elements. This means that the vector may be a syntax table. + However, according to this test, any vector of length 256 is + considered to be a syntax table, no matter what its contents. + + +File: lispref.info, Node: Syntax Descriptors, Next: Syntax Table Functions, Prev: Syntax Basics, Up: Syntax Tables + +Syntax Descriptors +================== + + This section describes the syntax classes and flags that denote the +syntax of a character, and how they are represented as a "syntax +descriptor", which is a Lisp string that you pass to +`modify-syntax-entry' to specify the desired syntax. + + XEmacs defines a number of "syntax classes". Each syntax table puts +each character into one class. There is no necessary relationship +between the class of a character in one syntax table and its class in +any other table. + + Each class is designated by a mnemonic character, which serves as the +name of the class when you need to specify a class. Usually the +designator character is one that is frequently in that class; however, +its meaning as a designator is unvarying and independent of what syntax +that character currently has. + + A syntax descriptor is a Lisp string that specifies a syntax class, a +matching character (used only for the parenthesis classes) and flags. +The first character is the designator for a syntax class. The second +character is the character to match; if it is unused, put a space there. +Then come the characters for any desired flags. If no matching +character or flags are needed, one character is sufficient. + + For example, the descriptor for the character `*' in C mode is +`. 23' (i.e., punctuation, matching character slot unused, second +character of a comment-starter, first character of an comment-ender), +and the entry for `/' is `. 14' (i.e., punctuation, matching character +slot unused, first character of a comment-starter, second character of +a comment-ender). + +* Menu: + +* Syntax Class Table:: Table of syntax classes. +* Syntax Flags:: Additional flags each character can have. + + +File: lispref.info, Node: Syntax Class Table, Next: Syntax Flags, Up: Syntax Descriptors + +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 + "Whitespace characters" (designated with ` ' or `-') separate + symbols and words from each other. Typically, whitespace + characters have no other syntactic significance, and multiple + whitespace characters are syntactically equivalent to a single + one. Space, tab, newline and formfeed are almost always + classified as whitespace. + + - 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 + "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 + used in Lisp mode to indicate that certain characters may be part + of symbol names even though they are not part of English words. + These characters are `$&*+-_<>'. In standard C, the only + non-word-constituent character that is valid in symbols is + underscore (`_'). + + - 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 + language modes, including Emacs Lisp mode, have no characters in + 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 + 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 + terminated with a close. Each open parenthesis character matches + a particular close parenthesis character, and vice versa. + Normally, XEmacs indicates momentarily the matching open + parenthesis when you insert a close parenthesis. *Note Blinking::. + + The class of open parentheses is designated with `(', and that of + close parentheses with `)'. + + In English text, and in C code, the parenthesis pairs are `()', + `[]', and `{}'. In XEmacs Lisp, the delimiters for lists and + vectors (`()' and `[]') are classified as parenthesis characters. + + - 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 + of a string. Such quoted strings do not nest. + + The parsing facilities of XEmacs consider a string as a single + token. The usual syntactic meanings of the characters in the + string are suppressed. + + The Lisp modes have two string quote characters: double-quote (`"') + and vertical bar (`|'). `|' is not used in XEmacs Lisp, but it is + used in Common Lisp. C also has two string quote characters: + double-quote for strings, and single-quote (`'') for character + constants. + + English text has no string quote characters because English is not + a programming language. Although quotation marks are used in + 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 + is used thus only inside strings, but it turns out to cause no + trouble to treat it this way throughout C code.) + + Characters in this class count as part of words if + `words-include-escapes' is non-`nil'. *Note Word Motion::. + + - Syntax class: character quote + 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 + immediately following is ever affected. + + Characters in this class count as part of words if + `words-include-escapes' is non-`nil'. *Note Word Motion::. + + This class is used for backslash in TeX mode. + + - 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 + 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 + 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 + 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 `@'. + + +File: lispref.info, Node: Syntax Flags, Prev: Syntax Class Table, Up: Syntax Descriptors + +Syntax Flags +------------ + + In addition to the classes, entries for characters in a syntax table +can include flags. There are six possible flags, represented by the +characters `1', `2', `3', `4', `b' and `p'. + + All the flags except `p' are used to describe multi-character +comment delimiters. The digit flags indicate that a character can +_also_ be part of a comment sequence, in addition to the syntactic +properties associated with its character class. The flags are +independent of the class and each other for the sake of characters such +as `*' in C mode, which is a punctuation character, _and_ the second +character of a start-of-comment sequence (`/*'), _and_ the first +character of an end-of-comment sequence (`*/'). + + The flags for a character C are: + + * `1' means C is the start of a two-character comment-start sequence. + + * `2' means C is the second character of such a sequence. + + * `3' means C is the start of a two-character comment-end sequence. + + * `4' means C is the second character of such a sequence. + + * `b' means that C as a comment delimiter belongs to the alternative + "b" comment style. + + Emacs supports two comment styles simultaneously in any one syntax + table. This is for the sake of C++. Each style of comment syntax + has its own comment-start sequence and its own comment-end + sequence. Each comment must stick to one style or the other; + thus, if it starts with the comment-start sequence of style "b", + it must also end with the comment-end sequence of style "b". + + The two comment-start sequences must begin with the same + character; only the second character may differ. Mark the second + character of the "b"-style comment-start sequence with the `b' + flag. + + A comment-end sequence (one or two characters) applies to the "b" + style if its first character has the `b' flag set; otherwise, it + applies to the "a" style. + + The appropriate comment syntax settings for C++ are as follows: + + `/' + `124b' + + `*' + `23' + + newline + `>b' + + This defines four comment-delimiting sequences: + + `/*' + This is a comment-start sequence for "a" style because the + second character, `*', does not have the `b' flag. + + `//' + This is a comment-start sequence for "b" style because the + second character, `/', does have the `b' flag. + + `*/' + This is a comment-end sequence for "a" style because the first + character, `*', does not have the `b' flag + + newline + This is a comment-end sequence for "b" style, because the + newline character has the `b' flag. + + * `p' identifies an additional "prefix character" for Lisp syntax. + These characters are treated as whitespace when they appear between + expressions. When they appear within an expression, they are + handled according to their usual syntax codes. + + The function `backward-prefix-chars' moves back over these + characters, as well as over characters whose primary syntax class + is prefix (`''). *Note Motion and Syntax::. + + +File: lispref.info, Node: Syntax Table Functions, Next: Motion and Syntax, Prev: Syntax Descriptors, Up: Syntax Tables + +Syntax Table Functions +====================== + + In this section we describe functions for creating, accessing and +altering syntax tables. + + - Function: make-syntax-table &optional oldtable + This function creates a new syntax table.

The properties of an extent -primarily affect the way the text contained in the extent is displayed. -Extents can freely overlap each other in a buffer or string. Extents -are invisible to functions that merely examine the text of a buffer or -string. - - _Please note:_ An alternative way to add properties to a buffer or -string is to use text properties. *Note Text Properties::. - - An extent is logically a Lisp object consisting of a start position, -an end position, a buffer or string to which these positions refer, and -a property list. As text is inserted into a buffer, the start and end -positions of the extent are automatically adjusted as necessary to keep -the extent referring to the same text in the buffer. If text is -inserted at the boundary of an extent, the extent's `start-open' and -`end-open' properties control whether the text is included as part of -the extent. If the text bounded by an extent is deleted, the extent -becomes "detached"; its start and end positions are no longer -meaningful, but it maintains all its other properties and can later be -reinserted into a buffer. (None of these considerations apply to -strings, because text cannot be inserted into or deleted from a string.) - - Each extent has a face or list of faces associated with it, which -controls the way in which the text bounded by the extent is displayed. -If an extent's face is `nil' or its properties are partially undefined, -the corresponding properties from the default face for the frame is -used. If two or more extents overlap, or if a list of more than one -face is specified for a particular extent, the corresponding faces are -merged to determine the text's displayed properties. Every extent has -a "priority" that determines which face takes precedence if the faces -conflict. (If two extents have the same priority, the one that comes -later in the display order takes precedence. *Note display order: -Extent Endpoints.) Higher-numbered priority values correspond to a -higher priority, and priority values can be negative. Every extent is -created with a priority of 0, but this can be changed with -`set-extent-priority'. Within a single extent with a list of faces, -faces earlier in the list have a higher priority than faces later in -the list. - - Extents can be set to respond specially to key and mouse events -within the extent. An extent's `keymap' property controls the effect of -key and mouse strokes within the extent's text, and the `mouse-face' -property controls whether the extent is highlighted when the mouse moves -over it. *Note Extents and Events::. - - An extent can optionally have a "begin-glyph" or "end-glyph" -associated with it. A begin-glyph or end-glyph is a pixmap or string -that will be displayed either at the start or end of an extent or in the -margin of the line that the start or end of the extent lies in, -depending on the extent's layout policy. Begin-glyphs and end-glyphs -are used to implement annotations, and you should use the annotation API -functions in preference to the lower-level extent functions. For more -information, *Note Annotations::. - - If an extent has its `detachable' property set, it will become -"detached" (i.e. no longer in the buffer) when all its text is deleted. -Otherwise, it will simply shrink down to zero-length and sit in the -same place in the buffer. By default, the `detachable' property is set -on newly-created extents. *Note Detached Extents::. - - If an extent has its `duplicable' property set, it will be -remembered when a string is created from text bounded by the extent. -When the string is re-inserted into a buffer, the extent will also be -re-inserted. This mechanism is used in the kill, yank, and undo -commands. *Note Duplicable Extents::. - - -File: lispref.info, Node: Creating and Modifying Extents, Next: Extent Endpoints, Prev: Intro to Extents, Up: Extents - -Creating and Modifying Extents -============================== - - - Function: make-extent from to &optional object - This function makes an extent for the range [FROM, TO) in OBJECT - (a buffer or string).

Normally the start and -end positions must both be valid positions in the extent's buffer or -string. However, both endpoints can be `nil', meaning the extent is -detached. *Note Detached Extents::. - - Whether the extent overlaps its endpoints is governed by its -`start-open' and `end-open' properties. Insertion of a character at a -closed endpoint will expand the extent to include that character; -insertion at an open endpoint will not. Similarly, functions such as -`extent-at' that scan over all extents overlapping a particular -position will include extents with a closed endpoint at that position, -but not extents with an open endpoint. - - Note that the `start-closed' and `end-closed' properties are -equivalent to `start-open' and `end-open' with the opposite sense. - - Both endpoints can be equal, in which case the extent includes no -characters but still exists in the buffer or string. Zero-length -extents are used to represent annotations (*note Annotations::) and can -be used as a more powerful form of a marker. Deletion of all the -characters in an extent may or may not result in a zero-length extent; -this depends on the `detachable' property (*note Detached Extents::). -Insertion at the position of a zero-length extent expands the extent if -both endpoints are closed; goes before the extent if it has the -`start-open' property; and goes after the extent if it has the -`end-open' property. Zero-length extents with both the `start-open' -and `end-open' properties are treated as if their starting point were -closed. Deletion of a character on a side of a zero-length extent -whose corresponding endpoint is closed causes the extent to be detached -if its `detachable' property is set; if the corresponding endpoint is -open, the extent remains in the buffer, moving as necessary. - - Extents are ordered within a buffer or string by increasing start -position, and then by decreasing end position (this is called the -"display order"). - - - Function: extent-start-position extent - This function returns the start position of EXTENT. - - - Function: extent-end-position extent - This function returns the end position of EXTENT. - - - Function: extent-length extent - This function returns the length of EXTENT in characters.

If both are `nil', this is equivalent to `detach-extent'. - - BUFFER-OR-STRING specifies the new buffer or string that the - extent should be in, and defaults to EXTENT's buffer or string. - (If `nil', and EXTENT is in no buffer and no string, it defaults - to the current buffer.) - - See documentation on `detach-extent' for a discussion of undo - recording. - - -File: lispref.info, Node: Finding Extents, Next: Mapping Over Extents, Prev: Extent Endpoints, Up: Extents - -Finding Extents -=============== - - The following functions provide a simple way of determining the -extents in a buffer or string. A number of more sophisticated -primitives for mapping over the extents in a range of a buffer or string -are also provided (*note Mapping Over Extents::). When reading through -this section, keep in mind the way that extents are ordered (*note -Extent Endpoints::). - - - Function: extent-list &optional buffer-or-string from to flags - This function returns a list of the extents in BUFFER-OR-STRING. - BUFFER-OR-STRING defaults to the current buffer if omitted. FROM - and TO can be used to limit the range over which extents are - returned; if omitted, all extents in the buffer or string are - returned. - - More specifically, if a range is specified using FROM and TO, only - extents that overlap the range (i.e. begin or end inside of the - range) are included in the list. FROM and TO default to the - beginning and end of BUFFER-OR-STRING, respectively. - - FLAGS controls how end cases are treated. For a discussion of - this, and exactly what "overlap" means, see `map-extents'. - - Functions that create extents must be prepared for the possibility -that there are other extents in the same area, created by other -functions. To deal with this, functions typically mark their own -extents by setting a particular property on them. The following -function makes it easier to locate those extents. - - - Function: extent-at pos &optional object property before at-flag - This function finds the "smallest" extent (i.e., the last one in - the display order) at (i.e., overlapping) POS in OBJECT (a buffer - or string) having PROPERTY set. OBJECT defaults to the current - buffer. PROPERTY defaults to `nil', meaning that any extent will - do. Returns `nil' if there is no matching extent at POS. If the - fourth argument BEFORE is not `nil', it must be an extent; any - returned extent will precede that extent. This feature allows - `extent-at' to be used by a loop over extents. - - AT-FLAG controls how end cases are handled (i.e. what "at" really - means), and should be one of: - - `nil' - - `after' - An extent is at POS if it covers the character after POS. - This is consistent with the way that text properties work. - - `before' - An extent is at POS if it covers the character before POS. - - `at' - An extent is at POS if it overlaps or abuts POS. This - includes all zero-length extents at POS. - - Note that in all cases, the start-openness and end-openness of the - extents considered is ignored. If you want to pay attention to - those properties, you should use `map-extents', which gives you - more control. - - The following low-level functions are provided for explicitly -traversing the extents in a buffer according to the display order. -These functions are mostly intended for debugging--in normal operation, -you should probably use `mapcar-extents' or `map-extents', or loop -using the BEFORE argument to `extent-at', rather than creating a loop -using `next-extent'. - - - Function: next-extent extent - Given an extent EXTENT, this function returns the next extent in - the buffer or string's display order. If EXTENT is a buffer or - string, this returns the first extent in the buffer or string. - - - Function: previous-extent extent - Given an extent EXTENT, this function returns the previous extent - in the buffer or string's display order.

You should read through the definition of this -function to familiarize yourself with the concepts and optional -arguments involved. However, in practice you may find it more -convenient to use the function `mapcar-extents' or to create a loop -using the `before' argument to `extent-at' (*note Finding Extents::). - - - Function: map-extents function &optional object from to maparg flags - property value - This function maps FUNCTION over the extents which overlap a - region in OBJECT. OBJECT is normally a buffer or string but could - be an extent (see below). The region is normally bounded by - [FROM, TO) (i.e. the beginning of the region is closed and the end - of the region is open), but this can be changed with the FLAGS - argument (see below for a complete discussion). - - FUNCTION is called with the arguments (extent, MAPARG). The - arguments OBJECT, FROM, TO, MAPARG, and FLAGS are all optional and - default to the current buffer, the beginning of OBJECT, the end of - OBJECT, NIL, and NIL, respectively. `map-extents' returns the - first non-`nil' result produced by FUNCTION, and no more calls to - FUNCTION are made after it returns non-`nil'. - - If OBJECT is an extent, FROM and TO default to the extent's - endpoints, and the mapping omits that extent and its predecessors. - This feature supports restarting a loop based on `map-extents'. - Note: OBJECT must be attached to a buffer or string, and the - mapping is done over that buffer or string. - - An extent overlaps the region if there is any point in the extent - that is also in the region. (For the purpose of overlap, - zero-length extents and regions are treated as closed on both ends - regardless of their endpoints' specified open/closedness.) Note - that the endpoints of an extent or region are considered to be in - that extent or region if and only if the corresponding end is - closed. For example, the extent [5,7] overlaps the region [2,5] - because 5 is in both the extent and the region. However, (5,7] - does not overlap [2,5] because 5 is not in the extent, and neither - [5,7] nor (5,7] overlaps the region [2,5) because 5 is not in the - region. - - The optional FLAGS can be a symbol or a list of one or more - symbols, modifying the behavior of `map-extents'. Allowed symbols - are: - - `end-closed' - The region's end is closed. - - `start-open' - The region's start is open. - - `all-extents-closed' - Treat all extents as closed on both ends for the purpose of - determining whether they overlap the region, irrespective of - their actual open- or closedness. - - `all-extents-open' - Treat all extents as open on both ends. - - `all-extents-closed-open' - Treat all extents as start-closed, end-open. - - `all-extents-open-closed' - Treat all extents as start-open, end-closed. - - `start-in-region' - In addition to the above conditions for extent overlap, the - extent's start position must lie within the specified region. - Note that, for this condition, open start positions are - treated as if 0.5 was added to the endpoint's value, and open - end positions are treated as if 0.5 was subtracted from the - endpoint's value. - - `end-in-region' - The extent's end position must lie within the region. - - `start-and-end-in-region' - Both the extent's start and end positions must lie within the - region. - - `start-or-end-in-region' - Either the extent's start or end position must lie within the - region. - - `negate-in-region' - The condition specified by a `*-in-region' flag must _not_ - hold for the extent to be considered. - - At most one of `all-extents-closed', `all-extents-open', - `all-extents-closed-open', and `all-extents-open-closed' may be - specified. - - At most one of `start-in-region', `end-in-region', - `start-and-end-in-region', and `start-or-end-in-region' may be - specified. - - If optional arg PROPERTY is non-`nil', only extents with that - property set on them will be visited. If optional arg VALUE is - non-`nil', only extents whose value for that property is `eq' to - VALUE will be visited. - - If you want to map over extents and accumulate a list of results, -the following function may be more convenient than `map-extents'. - - - 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 - TO. FUNCTION is called with one argument, the extent. A list of - the values returned by FUNCTION is returned. An optional - PREDICATE may be used to further limit the extents over which - FUNCTION is mapped.

The + arguments OBJECT, FROM, TO, MAPARG, and FLAGS are all optional and + default to the current buffer, the beginning of OBJECT, the end of + OBJECT, `nil', and `nil', respectively. `map-extents' returns the + first non-`nil' result produced by FUNCTION, and no more calls to + FUNCTION are made after it returns non-`nil'. + + If OBJECT is an extent, FROM and TO default to the extent's + endpoints, and the mapping omits that extent and its predecessors. + This feature supports restarting a loop based on `map-extents'. + Note: OBJECT must be attached to a buffer or string, and the + mapping is done over that buffer or string. + + An extent overlaps the region if there is any point in the extent + that is also in the region.

This involves looking through the specifications to see -which ones apply to this particular situation, and perhaps preferring -one over another if more than one applies. In specifier terminology, a -"particular situation" is called a "domain", and determining its value -in a particular domain is called "instancing". Most of the time, a -domain is identified by a particular window. For example, if the -redisplay engine is drawing text in the default face in a particular -window, it retrieves the specifier for the foreground color of the -default face and "instances" it in the domain given by that window; in -other words, it asks the specifier, "What is your value in this -window?". - - More specifically, a specifier contains a set of "specifications", -each of which associates a "locale" (a window object, a buffer object, -a frame object, a device object, or the symbol `global') with an -"inst-list", which is a list of one or more "inst-pairs". (For each -possible locale, there can be at most one specification containing that -locale.) Each inst-pair is a cons of a "tag set" (an unordered list of -zero or more symbols, or "tags") and an "instantiator" (the allowed -form of this varies depending on the type of specifier). In a given -specification, there may be more than one inst-pair with the same tag -set; this is unlike for locales. - - The tag set is used to restrict the sorts of devices over which the -instantiator is valid and to uniquely identify instantiators added by a -particular application, so that different applications can work on the -same specifier and not interfere with each other. Each tag can have a -"predicate" associated with it, which is a function of one argument (a -device) that specifies whether the tag matches that particular device. -(If a tag does not have a predicate, it matches all devices.) All tags -in a tag set must match a device for the associated inst-pair to be -instantiable over that device.

For example, for font specifiers, the instantiator is a -font-description string and the instance object is a font-instance -object, which describes how the font is displayed on a particular -device. A font-instance object encapsulates such things as the actual -font name used to display the font on that device (a font-description -string under X is usually a wildcard specification that may resolve to -different font names, with possibly different foundries, widths, etc., -on different devices), the extra properties of that font on that -device, etc. Furthermore, this conversion (called "instantiation") -might fail--a font or color might not exist on a particular device, for -example. - - -File: lispref.info, Node: Specifier Instancing, Next: Specifier Types, Prev: Specifiers In-Depth, Up: Specifiers - -How a Specifier Is Instanced -============================ - - Instancing of a specifier in a particular window domain proceeds as -follows: - - * First, XEmacs searches for a specification whose locale is the - same as the window.

If - that fails, the search is repeated using the window's frame, then - using the device that frame is on.

If it succeeds, the resulting - instance object is returned as the result of the instancing and - the instancing is done. Otherwise, the operation continues, - looking for another matching inst-pair in the current - specification. - - * When there are no more inst-pairs to be considered in the current - specification, the search starts over, looking for another - specification as in the first step above. - - * If all specifications are exhausted and no instance object can be - derived, the instancing fails. (Actually, this is not completely - true. Some specifier objects for built-in properties have a - "fallback" value, which is either an inst-list or another - specifier object, that is consulted if the instancing is about to - fail.

Fallback values are set by the C code and cannot be - modified, except perhaps indirectly, using any Lisp functions. - The purpose of them is to supply some values to make sure that - instancing of built-in properties can't fail and to implement some - basic specifier inheritance, such as the fact that faces inherit - their properties from the `default' face.) - - It is also possible to instance a specifier over a frame domain or -device domain instead of over a window domain. The C code, for example, -instances the `top-toolbar-height' variable over a frame domain in -order to determine the height of a frame's top toolbar. Instancing over -a frame or device is similar to instancing over a window except that -specifications for locales that cannot be derived from the domain are -ignored.

The type of a -specifier controls what sorts of instantiators are valid, how an -instantiator is instantiated, etc. Here is a list of built-in specifier -types: - -`boolean' - The valid instantiators are the symbols `t' and `nil'. Instance - objects are the same as instantiators so no special instantiation - function is needed. - -`integer' - The valid instantiators are integers. Instance objects are the - same as instantiators so no special instantiation function is - needed. `modeline-shadow-thickness' is an example of an integer - specifier (negative thicknesses indicate that the shadow is drawn - recessed instead of raised). - -`natnum' - The valid instantiators are natnums (non-negative integers). - Instance objects are the same as instantiators so no special - instantiation function is needed. Natnum specifiers are used for - dimension variables such as `top-toolbar-height'. - -`generic' - All Lisp objects are valid instantiators. Instance objects are - the same as instantiators so no special instantiation function is - needed. - -`font' - The valid instantiators are strings describing fonts or vectors - indicating inheritance from the font of some face. Instance - objects are font-instance objects, which are specific to a - particular device. The instantiation method for font specifiers - can fail, unlike for integer, natnum, boolean, and generic - specifiers. - -`color' - The valid instantiators are strings describing colors or vectors - indicating inheritance from the foreground or background of some - face. Instance objects are color-instance objects, which are - specific to a particular device. The instantiation method for - color specifiers can fail, as for font specifiers. - -`image' - Images are perhaps the most complicated type of built-in - specifier. The valid instantiators are strings (a filename, - inline data for a pixmap, or text to be displayed in a text glyph) - or vectors describing inline data of various sorts or indicating - inheritance from the background-pixmap property of some face. - Instance objects are either strings (for text images), - image-instance objects (for pixmap images), or subwindow objects - (for subwindow images). The instantiation method for image - specifiers can fail, as for font and color specifiers. - -`face-boolean' - The valid instantiators are the symbols `t' and `nil' and vectors - indicating inheritance from a boolean property of some face. - Specifiers of this sort are used for all of the built-in boolean - properties of faces. Instance objects are either the symbol `t' - or the symbol `nil'. - -`toolbar' - The valid instantiators are toolbar descriptors, which are lists - of toolbar-button descriptors (each of which is a vector of two or - four elements). *Note Toolbar::, for more information. - - Color and font instance objects can also be used in turn as -instantiators for a new color or font instance object.

In specifier terminology, these conditions are +called "locales" and the values are called "instantiators". Given a +specifier, a logical question is "What is its value in a particular +situation?" This involves looking through the specifications to see +which ones apply to this particular situation, and perhaps preferring +one over another if more than one applies. In specifier terminology, a +"particular situation" is called a "domain", and determining its value +in a particular domain is called "instancing". Most of the time, a +domain is identified by a particular window. For example, if the +redisplay engine is drawing text in the default face in a particular +window, it retrieves the specifier for the foreground color of the +default face and "instances" it in the domain given by that window; in +other words, it asks the specifier, "What is your value in this +window?". + + More specifically, a specifier contains a set of "specifications", +each of which associates a "locale" (a window object, a buffer object, +a frame object, a device object, or the symbol `global') with an +"inst-list", which is a list of one or more "inst-pairs". (For each +possible locale, there can be at most one specification containing that +locale.) Each inst-pair is a cons of a "tag set" (an unordered list of +zero or more symbols, or "tags") and an "instantiator" (the allowed +form of this varies depending on the type of specifier). In a given +specification, there may be more than one inst-pair with the same tag +set; this is unlike for locales. + + The tag set is used to restrict the sorts of devices over which the +instantiator is valid and to uniquely identify instantiators added by a +particular application, so that different applications can work on the +same specifier and not interfere with each other. Each tag can have a +"predicate" associated with it, which is a function of one argument (a +device) that specifies whether the tag matches that particular device. +(If a tag does not have a predicate, it matches all devices.) All tags +in a tag set must match a device for the associated inst-pair to be +instantiable over that device. (A null tag set is perfectly valid.) + + The valid device types (normally `x', `tty', and `stream') and +device classes (normally `color', `grayscale', and `mono') can always +be used as tags, and match devices of the associated type or class +(*note Consoles and Devices::). User-defined tags may be defined, with +an optional predicate specified. An application can create its own +tag, use it to mark all its instantiators, and be fairly confident that +it will not interfere with other applications that modify the same +specifier--Functions that add a specification to a specifier usually +only overwrite existing inst-pairs with the same tag set as was given, +and a particular tag or tag set can be specified when removing +instantiators. + + When a specifier is instanced in a domain, both the locale and the +tag set can be viewed as specifying necessary conditions that must +apply in that domain for an instantiator to be considered as a possible +result of the instancing. More specific locales always override more +general locales (thus, there is no particular ordering of the +specifications in a specifier); however, the tag sets are simply +considered in the order that the inst-pairs occur in the +specification's inst-list. + + Note also that the actual object that results from the instancing +(called an "instance object") may not be the same as the instantiator +from which it was derived. For some specifier types (such as integer +specifiers and boolean specifiers), the instantiator will be returned +directly as the instance object. For other types, however, this is not +the case. For example, for font specifiers, the instantiator is a +font-description string and the instance object is a font-instance +object, which describes how the font is displayed on a particular +device. A font-instance object encapsulates such things as the actual +font name used to display the font on that device (a font-description +string under X is usually a wildcard specification that may resolve to +different font names, with possibly different foundries, widths, etc., +on different devices), the extra properties of that font on that +device, etc. Furthermore, this conversion (called "instantiation") +might fail--a font or color might not exist on a particular device, for +example. + + +File: lispref.info, Node: Specifier Instancing, Next: Specifier Types, Prev: Specifiers In-Depth, Up: Specifiers + +How a Specifier Is Instanced +============================ + + Instancing of a specifier in a particular window domain proceeds as +follows: + + * First, XEmacs searches for a specification whose locale is the + same as the window. If that fails, the search is repeated, + looking for a locale that is the same as the window's buffer. If + that fails, the search is repeated using the window's frame, then + using the device that frame is on. Finally, the specification + whose locale is the symbol `global' (if there is such a + specification) is considered. + + * The inst-pairs contained in the specification that was found are + considered in their order in the inst-list, looking for one whose + tag set matches the device that is derived from the window domain. + (The tag set is an unordered list of zero or more tag symbols. + For all tags that have predicates associated with them, the + predicate must match the device.) + + * If a matching tag set is found, the corresponding instantiator is + passed to the specifier's instantiation method, which is specific + to the type of the specifier. If it succeeds, the resulting + instance object is returned as the result of the instancing and + the instancing is done. Otherwise, the operation continues, + looking for another matching inst-pair in the current + specification. + + * When there are no more inst-pairs to be considered in the current + specification, the search starts over, looking for another + specification as in the first step above. + + * If all specifications are exhausted and no instance object can be + derived, the instancing fails. (Actually, this is not completely + true. Some specifier objects for built-in properties have a + "fallback" value, which is either an inst-list or another + specifier object, that is consulted if the instancing is about to + fail. If it is an inst-list, the searching proceeds using the + inst-pairs in that list. If it is a specifier, the entire + instancing starts over using that specifier instead of the given + one. Fallback values are set by the C code and cannot be + modified, except perhaps indirectly, using any Lisp functions. + The purpose of them is to supply some values to make sure that + instancing of built-in properties can't fail and to implement some + basic specifier inheritance, such as the fact that faces inherit + their properties from the `default' face.) + + It is also possible to instance a specifier over a frame domain or +device domain instead of over a window domain. The C code, for example, +instances the `top-toolbar-height' variable over a frame domain in +order to determine the height of a frame's top toolbar. Instancing over +a frame or device is similar to instancing over a window except that +specifications for locales that cannot be derived from the domain are +ignored. Specifically, instancing over a frame looks first for frame +locales, then device locales, then the `global' locale. Instancing +over a device domain looks only for device locales and the `global' +locale. + + +File: lispref.info, Node: Specifier Types, Next: Adding Specifications, Prev: Specifier Instancing, Up: Specifiers + +Specifier Types +=============== + + There are various different types of specifiers. The type of a +specifier controls what sorts of instantiators are valid, how an +instantiator is instantiated, etc. Here is a list of built-in specifier +types: + +`boolean' + The valid instantiators are the symbols `t' and `nil'. Instance + objects are the same as instantiators so no special instantiation + function is needed. + +`integer' + The valid instantiators are integers. Instance objects are the + same as instantiators so no special instantiation function is + needed. `modeline-shadow-thickness' is an example of an integer + specifier (negative thicknesses indicate that the shadow is drawn + recessed instead of raised). + +`natnum' + The valid instantiators are natnums (non-negative integers). + Instance objects are the same as instantiators so no special + instantiation function is needed. Natnum specifiers are used for + dimension variables such as `top-toolbar-height'. + +`generic' + All Lisp objects are valid instantiators. Instance objects are + the same as instantiators so no special instantiation function is + needed. + +`font' + The valid instantiators are strings describing fonts or vectors + indicating inheritance from the font of some face. Instance + objects are font-instance objects, which are specific to a + particular device. The instantiation method for font specifiers + can fail, unlike for integer, natnum, boolean, and generic + specifiers. + +`color' + The valid instantiators are strings describing colors or vectors + indicating inheritance from the foreground or background of some + face. Instance objects are color-instance objects, which are + specific to a particular device. The instantiation method for + color specifiers can fail, as for font specifiers. + +`image' + Images are perhaps the most complicated type of built-in + specifier. The valid instantiators are strings (a filename, + inline data for a pixmap, or text to be displayed in a text glyph) + or vectors describing inline data of various sorts or indicating + inheritance from the background-pixmap property of some face. + Instance objects are either strings (for text images), + image-instance objects (for pixmap images), or subwindow objects + (for subwindow images). The instantiation method for image + specifiers can fail, as for font and color specifiers. + +`face-boolean' + The valid instantiators are the symbols `t' and `nil' and vectors + indicating inheritance from a boolean property of some face. + Specifiers of this sort are used for all of the built-in boolean + properties of faces. Instance objects are either the symbol `t' + or the symbol `nil'. + +`toolbar' + The valid instantiators are toolbar descriptors, which are lists + of toolbar-button descriptors (each of which is a vector of two or + four elements). *Note Toolbar::, for more information. + + Color and font instance objects can also be used in turn as +instantiators for a new color or font instance object. Since these +instance objects are device-specific, the instantiator can be used +directly as the new instance object, but only if they are of the same +device. If the devices differ, the base color or font of the +instantiating object is effectively used instead as the instantiator. + + *Note Faces and Window-System Objects::, for more information on +fonts, colors, and face-boolean specifiers. *Note Glyphs::, for more +information about image specifiers. *Note Toolbar::, for more +information on toolbar specifiers. + + - Function: specifier-type specifier + This function returns the type of SPECIFIER.

A key/value pair is sometimes called an "entry" in -the hash table. There are many ways other than hash tables of -implementing the same sort of mapping, e.g. association lists (*note -Association Lists::) and property lists (*note Property Lists::), but -hash tables provide much faster lookup when there are many entries in -the mapping. Hash tables are an implementation of the abstract data -type "dictionary", also known as "associative array". - - Internally, hash tables are hashed using the "linear probing" hash -table implementation method. This method hashes each key to a -particular spot in the hash table, and then scans forward sequentially -until a blank entry is found. To look up a key, hash to the appropriate -spot, then search forward for the key until either a key is found or a -blank entry stops the search. This method is used in preference to -double hashing because of changes in recent hardware. The penalty for -non-sequential access to memory has been increasing, and this -compensates for the problem of clustering that linear probing entails. - - When hash tables are created, the user may (but is not required to) -specify initial properties that influence performance. - - Use the `:size' parameter to specify the number of entries that are -likely to be stored in the hash table, to avoid the overhead of resizing -the table. But if the pre-allocated space for the entries is never -used, it is simply wasted and makes XEmacs slower. Excess unused hash -table entries exact a small continuous performance penalty, since they -must be scanned at every garbage collection. If the number of entries -in the hash table is unknown, simply avoid using the `:size' keyword. - - Use the `:rehash-size' and `:rehash-threshold' keywords to adjust -the algorithm for deciding when to rehash the hash table. For -temporary hash tables that are going to be very heavily used, use a -small rehash threshold, for example, 0.4 and a large rehash size, for -example 2.0. For permanent hash tables that will be infrequently used, -specify a large rehash threshold, for example 0.8. - - Hash tables can also be created by the lisp reader using structure -syntax, for example: - #s(hash-table size 20 data (foo 1 bar 2)) - - The structure syntax accepts the same keywords as `make-hash-table' -(without the `:' character), as well as the additional keyword `data', -which specifies the initial hash table contents. - - - Function: make-hash-table &key `test' `size' `rehash-size' - `rehash-threshold' `weakness' - This function returns a new empty hash table object. - - Keyword `:test' can be `eq', `eql' (default) or `equal'. - Comparison between keys is done using this function. If speed is - important, consider using `eq'. When storing strings in the hash - table, you will likely need to use `equal'. - - Keyword `:size' specifies the number of keys likely to be inserted. - This number of entries can be inserted without enlarging the hash - table. - - Keyword `:rehash-size' must be a float greater than 1.0, and - specifies the factor by which to increase the size of the hash - table when enlarging. - - Keyword `:rehash-threshold' must be a float between 0.0 and 1.0, - and specifies the load factor of the hash table which triggers - enlarging. - - Non-standard keyword `:weakness' can be `nil' (default), `t', - `key-and-value', `key', `value' or `key-or-value'. `t' is an - alias for `key-and-value'. - - A key-and-value-weak hash table, also known as a fully-weak or - simply as a weak hash table, is one whose pointers do not count as - GC referents: for any key-value pair in the hash table, if the only - remaining pointer to either the key or the value is in a weak hash - table, then the pair will be removed from the hash table, and the - key and value collected.

XEmacs also sends signals automatically at certain times: +killing a buffer sends a `SIGHUP' signal to all its associated +processes; killing XEmacs sends a `SIGHUP' signal to all remaining +processes. (`SIGHUP' is a signal that indicates that the connection +between the user and the process is broken, for example if a connection +via a telephone line is hung up.) + + Each of the signal-sending functions takes two optional arguments: +PROCESS and CURRENT-GROUP. + + The argument PROCESS must be either a process or a buffer, the name +of one, or `nil'. If it is `nil', the process defaults to the process +associated with the current buffer. An error is signaled if PROCESS +does not identify a process. + + The argument CURRENT-GROUP is a flag that makes a difference when +you are running a job-control shell as an XEmacs subprocess. If it is +non-`nil', then the signal is sent to the current foreground process +group of the terminal that XEmacs uses to communicate with the +subprocess. If the process is a job-control shell, this means the +shell's current subjob. If it is `nil', the signal is sent to the +process group of the immediate subprocess of XEmacs. If the subprocess +is a job-control shell, this is the shell itself. + + The flag CURRENT-GROUP has no effect when a pipe is used to +communicate with the subprocess, because the operating system does not +support the distinction in the case of pipes.

You +can also use the buffer to identify a process to operate on, since in +normal practice only one process is associated with any given buffer. +Many applications of processes also use the buffer for editing input to +be sent to the process, but this is not built into XEmacs Lisp. + + Unless the process has a filter function (*note Filter Functions::), +its output is inserted in the associated buffer. The position to insert +the output is determined by the `process-mark', which is then updated +to point to the end of the text just inserted.

If a process has a filter, then +_all_ output from that process is passed to the filter. The process +buffer is used directly for output from the process only when there is +no filter. + + A filter function must accept two arguments: the associated process +and a string, which is the output. The function is then free to do +whatever it chooses with the output. + + A filter function runs only while XEmacs is waiting (e.g., for +terminal input, or for time to elapse, or for process output). This +avoids the timing errors that could result from running filters at +random places in the middle of other Lisp programs. You may explicitly +cause Emacs to wait, so that filter functions will run, by calling +`sit-for' or `sleep-for' (*note Waiting::), or `accept-process-output' +(*note Accepting Output::). Emacs is also waiting when the command loop +is reading input. + + Quitting is normally inhibited within a filter function--otherwise, +the effect of typing `C-g' at command level or to quit a user command +would be unpredictable. If you want to permit quitting inside a filter +function, bind `inhibit-quit' to `nil'. *Note Quitting::. + + If an error happens during execution of a filter function, it is +caught automatically, so that it doesn't stop the execution of whatever +program was running when the filter function was started. However, if +`debug-on-error' is non-`nil', the error-catching is turned off. This +makes it possible to use the Lisp debugger to debug the filter +function. *Note Debugger::. + + Many filter functions sometimes or always insert the text in the +process's buffer, mimicking the actions of XEmacs when there is no +filter. Such filter functions need to use `set-buffer' in order to be +sure to insert in that buffer. To avoid setting the current buffer +semipermanently, these filter functions must use `unwind-protect' to +make sure to restore the previous current buffer. They should also +update the process marker, and in some cases update the value of point. +Here is how to do these things: + + (defun ordinary-insertion-filter (process string) + (let ((old-buffer (current-buffer))) + (unwind-protect + (let (moving) + (set-buffer (process-buffer process)) + (setq moving (= (point) (process-mark process))) + (save-excursion + ;; Insert the text, moving the process-marker. + (goto-char (process-mark process)) + (insert string) + (set-marker (process-mark process) (point))) + (if moving (goto-char (process-mark process)))) + (set-buffer old-buffer)))) + +The reason to use an explicit `unwind-protect' rather than letting +`save-excursion' restore the current buffer is so as to preserve the +change in point made by `goto-char'. + + To make the filter force the process buffer to be visible whenever +new text arrives, insert the following line just before the +`unwind-protect': + + (display-buffer (process-buffer process)) + + To force point to move to the end of the new output no matter where +it was previously, eliminate the variable `moving' and call `goto-char' +unconditionally. + + In earlier Emacs versions, every filter function that did regexp +searching or matching had to explicitly save and restore the match data. +Now Emacs does this automatically; filter functions never need to do it +explicitly. *Note Match Data::. + + A filter function that writes the output into the buffer of the +process should check whether the buffer is still alive.

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'.

Note that -the same character may be drawn by two different people (or in two -different fonts) in slightly different ways, although the "basic shape" -will be the same. But consider the works of Scott Kim; human beings -can recognize hugely variant shapes as the "same" character. -Sometimes, especially where characters are extremely complicated to -write, completely different shapes may be defined as the "same" -character in national standards. The Taiwanese variant of Hanzi is -generally the most complicated; over the centuries, the Japanese, -Koreans, and the People's Republic of China have adopted -simplifications of the shape, but the line of descent from the original -shape is recorded, and the meanings and pronunciation of different -forms of the same character are considered to be identical within each -language. (Of course, it may take a specialist to recognize the -related form; the point is that the relations are standardized, despite -the differing shapes.) - - In some cases, the differences will be significant enough that it is -actually possible to identify two or more distinct shapes that both -represent the same character. For example, the lowercase letters `a' -and `g' each have two distinct possible shapes--the `a' can optionally -have a curved tail projecting off the top, and the `g' can be formed -either of two loops, or of one loop and a tail hanging off the bottom. -Such distinct possible shapes of a character are called "glyphs". The -important characteristic of two glyphs making up the same character is -that the choice between one or the other is purely stylistic and has no -linguistic effect on a word (this is the reason why a capital `A' and -lowercase `a' are different characters rather than different -glyphs--e.g. `Aspen' is a city while `aspen' is a kind of tree). - - Note that "character" and "glyph" are used differently here than -elsewhere in XEmacs. - - A "character set" is essentially a set of related characters. ASCII, -for example, is a set of 94 characters (or 128, if you count -non-printing characters). Other character sets are ISO8859-1 (ASCII -plus various accented characters and other international symbols), JIS -X 0201 (ASCII, more or less, plus half-width Katakana), JIS X 0208 -(Japanese Kanji), JIS X 0212 (a second set of less-used Japanese Kanji), -GB2312 (Mainland Chinese Hanzi), etc. - - The definition of a character set will implicitly or explicitly give -it an "ordering", a way of assigning a number to each character in the -set. For many character sets, there is a natural ordering, for example -the "ABC" ordering of the Roman letters. But it is not clear whether -digits should come before or after the letters, and in fact different -European languages treat the ordering of accented characters -differently. It is useful to use the natural order where available, of -course. The number assigned to any particular character is called the -character's "code point". (Within a given character set, each -character has a unique code point. Thus the word "set" is ill-chosen; -different orderings of the same characters are different character sets. -Identifying characters is simple enough for alphabetic character sets, -but the difference in ordering can cause great headaches when the same -thousands of characters are used by different cultures as in the Hanzi.) - - A code point may be broken into a number of "position codes". The -number of position codes required to index a particular character in a -character set is called the "dimension" of the character set. For -practical purposes, a position code may be thought of as a byte-sized -index. The printing characters of ASCII, being a relatively small -character set, is of dimension one, and each character in the set is -indexed using a single position code, in the range 1 through 94. Use of -this unusual range, rather than the familiar 33 through 126, is an -intentional abstraction; to understand the programming issues you must -break the equation between character sets and encodings. - - JIS X 0208, i.e. Japanese Kanji, has thousands of characters, and is -of dimension two - every character is indexed by two position codes, -each in the range 1 through 94. (This number "94" is not a -coincidence; we shall see that the JIS position codes were chosen so -that JIS kanji could be encoded without using codes that in ASCII are -associated with device control functions.) Note that the choice of the -range here is somewhat arbitrary. You could just as easily index the -printing characters in ASCII using numbers in the range 0 through 93, 2 -through 95, 3 through 96, etc. In fact, the standardized _encoding_ -for the ASCII _character set_ uses the range 33 through 126. - - An "encoding" is a way of numerically representing characters from -one or more character sets into a stream of like-sized numerical values -called "words"; typically these are 8-bit, 16-bit, or 32-bit -quantities. If an encoding encompasses only one character set, then the -position codes for the characters in that character set could be used -directly. (This is the case with the trivial cipher used by children, -assigning 1 to `A', 2 to `B', and so on.) However, even with ASCII, -other considerations intrude. For example, why are the upper- and -lowercase alphabets separated by 8 characters? Why do the digits start -with `0' being assigned the code 48? In both cases because semantically -interesting operations (case conversion and numerical value extraction) -become convenient masking operations. Other artificial aspects (the -control characters being assigned to codes 0-31 and 127) are historical -accidents. (The use of 127 for `DEL' is an artifact of the "punch -once" nature of paper tape, for example.) - - Naive use of the position code is not possible, however, if more than -one character set is to be used in the encoding. For example, printed -Japanese text typically requires characters from multiple character sets -- ASCII, JIS X 0208, and JIS X 0212, to be specific. Each of these is -indexed using one or more position codes in the range 1 through 94, so -the position codes could not be used directly or there would be no way -to tell which character was meant. Different Japanese encodings handle -this differently - JIS uses special escape characters to denote -different character sets; EUC sets the high bit of the position codes -for JIS X 0208 and JIS X 0212, and puts a special extra byte before each -JIS X 0212 character; etc. (JIS, EUC, and most of the other encodings -you will encounter in files are 7-bit or 8-bit encodings. There is one -common 16-bit encoding, which is Unicode; this strives to represent all -the world's characters in a single large character set. 32-bit -encodings are often used internally in programs, such as XEmacs with -MULE support, to simplify the code that manipulates them; however, they -are not used externally because they are not very space-efficient.) - - A general method of handling text using multiple character sets -(whether for multilingual text, or simply text in an extremely -complicated single language like Japanese) is defined in the -international standard ISO 2022. ISO 2022 will be discussed in more -detail later (*note ISO 2022::), but for now suffice it to say that text -needs control functions (at least spacing), and if escape sequences are -to be used, an escape sequence introducer. It was decided to make all -text streams compatible with ASCII in the sense that the codes 0-31 -(and 128-159) would always be control codes, never graphic characters, -and where defined by the character set the `SPC' character would be -assigned code 32, and `DEL' would be assigned 127. Thus there are 94 -code points remaining if 7 bits are used. This is the reason that most -character sets are defined using position codes in the range 1 through -94. Then ISO 2022 compatible encodings are produced by shifting the -position codes 1 to 94 into character codes 33 to 126, or (if 8 bit -codes are available) into character codes 161 to 254. - - Encodings are classified as either "modal" or "non-modal". In a -"modal encoding", there are multiple states that the encoding can be -in, and the interpretation of the values in the stream depends on the -current global state of the encoding. Special values in the encoding, -called "escape sequences", are used to change the global state. JIS, -for example, is a modal encoding. The bytes `ESC $ B' indicate that, -from then on, bytes are to be interpreted as position codes for JIS X -0208, rather than as ASCII. This effect is cancelled using the bytes -`ESC ( B', which mean "switch from whatever the current state is to -ASCII". To switch to JIS X 0212, the escape sequence `ESC $ ( D'. -(Note that here, as is common, the escape sequences do in fact begin -with `ESC'. This is not necessarily the case, however. Some encodings -use control characters called "locking shifts" (effect persists until -cancelled) to switch character sets.) - - A "non-modal encoding" has no global state that extends past the -character currently being interpreted. EUC, for example, is a -non-modal encoding. Characters in JIS X 0208 are encoded by setting -the high bit of the position codes, and characters in JIS X 0212 are -encoded by doing the same but also prefixing the character with the -byte 0x8F. - - The advantage of a modal encoding is that it is generally more -space-efficient, and is easily extendible because there are essentially -an arbitrary number of escape sequences that can be created. The -disadvantage, however, is that it is much more difficult to work with -if it is not being processed in a sequential manner. In the non-modal -EUC encoding, for example, the byte 0x41 always refers to the letter -`A'; whereas in JIS, it could either be the letter `A', or one of the -two position codes in a JIS X 0208 character, or one of the two -position codes in a JIS X 0212 character. Determining exactly which -one is meant could be difficult and time-consuming if the previous -bytes in the string have not already been processed, or impossible if -they are drawn from an external stream that cannot be rewound. - - Non-modal encodings are further divided into "fixed-width" and -"variable-width" formats. A fixed-width encoding always uses the same -number of words per character, whereas a variable-width encoding does -not. EUC is a good example of a variable-width encoding: one to three -bytes are used per character, depending on the character set. 16-bit -and 32-bit encodings are nearly always fixed-width, and this is in fact -one of the main reasons for using an encoding with a larger word size. -The advantages of fixed-width encodings should be obvious. The -advantages of variable-width encodings are that they are generally more -space-efficient and allow for compatibility with existing 8-bit -encodings such as ASCII. (For example, in Unicode ASCII characters are -simply promoted to a 16-bit representation. That means that every -ASCII character contains a `NUL' byte; evidently all of the standard -string manipulation functions will lose badly in a fixed-width Unicode -environment.) - - The bytes in an 8-bit encoding are often referred to as "octets" -rather than simply as bytes. This terminology dates back to the days -before 8-bit bytes were universal, when some computers had 9-bit bytes, -others had 10-bit bytes, etc. - - -File: lispref.info, Node: Charsets, Next: MULE Characters, Prev: Internationalization Terminology, Up: MULE - -Charsets -======== - - A "charset" in MULE is an object that encapsulates a particular -character set as well as an ordering of those characters.

Every charset must have a different - name; this allows a charset to be referred to using its name - rather than the actual charset object. - -`doc-string' - A documentation string describing the charset. - -`registry' - A regular expression matching the font registry field for this - character set. For example, both the `ascii' and `latin-iso8859-1' - charsets use the registry `"ISO8859-1"'. This field is used to - choose an appropriate font when the user gives a general font - specification such as `-*-courier-medium-r-*-140-*', i.e. a - 14-point upright medium-weight Courier font. - -`dimension' - Number of position codes used to index a character in the - character set. XEmacs/MULE can only handle character sets of - dimension 1 or 2. This property defaults to 1. - -`chars' - Number of characters in each dimension. In XEmacs/MULE, the only - allowed values are 94 or 96. (There are a couple of pre-defined - character sets, such as ASCII, that do not follow this, but you - cannot define new ones like this.) Defaults to 94. Note that if - the dimension is 2, the character set thus described is 94x94 or - 96x96. - -`columns' - Number of columns used to display a character in this charset. - Only used in TTY mode. (Under X, the actual width of a character - can be derived from the font used to display the characters.) If - unspecified, defaults to the dimension. (This is almost always the - correct value, because character sets with dimension 2 are usually - ideograph character sets, which need two columns to display the - intricate ideographs.) - -`direction' - A symbol, either `l2r' (left-to-right) or `r2l' (right-to-left). - Defaults to `l2r'. This specifies the direction that the text - should be displayed in, and will be left-to-right for most - charsets but right-to-left for Hebrew and Arabic. (Right-to-left - display is not currently implemented.) - -`final' - Final byte of the standard ISO 2022 escape sequence designating - this charset. Must be supplied. Each combination of (DIMENSION, - CHARS) defines a separate namespace for final bytes, and each - charset within a particular namespace must have a different final - byte. Note that ISO 2022 restricts the final byte to the range - 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if dimension == 2. - Note also that final bytes in the range 0x30 - 0x3F are reserved - for user-defined (not official) character sets. For more - information on ISO 2022, see *Note Coding Systems::. - -`graphic' - 0 (use left half of font on output) or 1 (use right half of font on - output). Defaults to 0. This specifies how to convert the - position codes that index a character in a character set into an - index into the font used to display the character set. With - `graphic' set to 0, position codes 33 through 126 map to font - indices 33 through 126; with it set to 1, position codes 33 - through 126 map to font indices 161 through 254 (i.e. the same - number but with the high bit set). For example, for a font whose - registry is ISO8859-1, the left half of the font (octets 0x20 - - 0x7F) is the `ascii' charset, while the right half (octets 0xA0 - - 0xFF) is the `latin-iso8859-1' charset. - -`ccl-program' - A compiled CCL program used to convert a character in this charset - into an index into the font. This is in addition to the `graphic' - property. If a CCL program is defined, the position codes of a - character will first be processed according to `graphic' and then - passed through the CCL program, with the resulting values used to - index the font. - - This is used, for example, in the Big5 character set (used in - Taiwan). This character set is not ISO-2022-compliant, and its - size (94x157) does not fit within the maximum 96x96 size of - ISO-2022-compliant character sets. As a result, XEmacs/MULE - splits it (in a rather complex fashion, so as to group the most - commonly used characters together) into two charset objects - (`big5-1' and `big5-2'), each of size 94x94, and each charset - object uses a CCL program to convert the modified position codes - back into standard Big5 indices to retrieve a character from a - Big5 font. - - Most of the above properties can only be set when the charset is -initialized, and cannot be changed later. *Note Charset Property -Functions::. - - -File: lispref.info, Node: Basic Charset Functions, Next: Charset Property Functions, Prev: Charset Properties, Up: Charsets - -Basic Charset Functions ------------------------ - - - Function: find-charset charset-or-name - This function retrieves the charset of the given name.

Note that +the same character may be drawn by two different people (or in two +different fonts) in slightly different ways, although the "basic shape" +will be the same. But consider the works of Scott Kim; human beings +can recognize hugely variant shapes as the "same" character. +Sometimes, especially where characters are extremely complicated to +write, completely different shapes may be defined as the "same" +character in national standards. The Taiwanese variant of Hanzi is +generally the most complicated; over the centuries, the Japanese, +Koreans, and the People's Republic of China have adopted +simplifications of the shape, but the line of descent from the original +shape is recorded, and the meanings and pronunciation of different +forms of the same character are considered to be identical within each +language. (Of course, it may take a specialist to recognize the +related form; the point is that the relations are standardized, despite +the differing shapes.) + + In some cases, the differences will be significant enough that it is +actually possible to identify two or more distinct shapes that both +represent the same character. For example, the lowercase letters `a' +and `g' each have two distinct possible shapes--the `a' can optionally +have a curved tail projecting off the top, and the `g' can be formed +either of two loops, or of one loop and a tail hanging off the bottom. +Such distinct possible shapes of a character are called "glyphs". The +important characteristic of two glyphs making up the same character is +that the choice between one or the other is purely stylistic and has no +linguistic effect on a word (this is the reason why a capital `A' and +lowercase `a' are different characters rather than different +glyphs--e.g. `Aspen' is a city while `aspen' is a kind of tree). + + Note that "character" and "glyph" are used differently here than +elsewhere in XEmacs. + + A "character set" is essentially a set of related characters. ASCII, +for example, is a set of 94 characters (or 128, if you count +non-printing characters). Other character sets are ISO8859-1 (ASCII +plus various accented characters and other international symbols), JIS +X 0201 (ASCII, more or less, plus half-width Katakana), JIS X 0208 +(Japanese Kanji), JIS X 0212 (a second set of less-used Japanese Kanji), +GB2312 (Mainland Chinese Hanzi), etc. + + The definition of a character set will implicitly or explicitly give +it an "ordering", a way of assigning a number to each character in the +set. For many character sets, there is a natural ordering, for example +the "ABC" ordering of the Roman letters. But it is not clear whether +digits should come before or after the letters, and in fact different +European languages treat the ordering of accented characters +differently. It is useful to use the natural order where available, of +course. The number assigned to any particular character is called the +character's "code point". (Within a given character set, each +character has a unique code point. Thus the word "set" is ill-chosen; +different orderings of the same characters are different character sets. +Identifying characters is simple enough for alphabetic character sets, +but the difference in ordering can cause great headaches when the same +thousands of characters are used by different cultures as in the Hanzi.) + + A code point may be broken into a number of "position codes". The +number of position codes required to index a particular character in a +character set is called the "dimension" of the character set. For +practical purposes, a position code may be thought of as a byte-sized +index. The printing characters of ASCII, being a relatively small +character set, is of dimension one, and each character in the set is +indexed using a single position code, in the range 1 through 94. Use of +this unusual range, rather than the familiar 33 through 126, is an +intentional abstraction; to understand the programming issues you must +break the equation between character sets and encodings. + + JIS X 0208, i.e. Japanese Kanji, has thousands of characters, and is +of dimension two - every character is indexed by two position codes, +each in the range 1 through 94. (This number "94" is not a +coincidence; we shall see that the JIS position codes were chosen so +that JIS kanji could be encoded without using codes that in ASCII are +associated with device control functions.) Note that the choice of the +range here is somewhat arbitrary. You could just as easily index the +printing characters in ASCII using numbers in the range 0 through 93, 2 +through 95, 3 through 96, etc. In fact, the standardized _encoding_ +for the ASCII _character set_ uses the range 33 through 126. + + An "encoding" is a way of numerically representing characters from +one or more character sets into a stream of like-sized numerical values +called "words"; typically these are 8-bit, 16-bit, or 32-bit +quantities. If an encoding encompasses only one character set, then the +position codes for the characters in that character set could be used +directly. (This is the case with the trivial cipher used by children, +assigning 1 to `A', 2 to `B', and so on.) However, even with ASCII, +other considerations intrude. For example, why are the upper- and +lowercase alphabets separated by 8 characters? Why do the digits start +with `0' being assigned the code 48? In both cases because semantically +interesting operations (case conversion and numerical value extraction) +become convenient masking operations. Other artificial aspects (the +control characters being assigned to codes 0-31 and 127) are historical +accidents. (The use of 127 for `DEL' is an artifact of the "punch +once" nature of paper tape, for example.) + + Naive use of the position code is not possible, however, if more than +one character set is to be used in the encoding. For example, printed +Japanese text typically requires characters from multiple character sets +- ASCII, JIS X 0208, and JIS X 0212, to be specific. Each of these is +indexed using one or more position codes in the range 1 through 94, so +the position codes could not be used directly or there would be no way +to tell which character was meant. Different Japanese encodings handle +this differently - JIS uses special escape characters to denote +different character sets; EUC sets the high bit of the position codes +for JIS X 0208 and JIS X 0212, and puts a special extra byte before each +JIS X 0212 character; etc. (JIS, EUC, and most of the other encodings +you will encounter in files are 7-bit or 8-bit encodings. There is one +common 16-bit encoding, which is Unicode; this strives to represent all +the world's characters in a single large character set. 32-bit +encodings are often used internally in programs, such as XEmacs with +MULE support, to simplify the code that manipulates them; however, they +are not used externally because they are not very space-efficient.) + + A general method of handling text using multiple character sets +(whether for multilingual text, or simply text in an extremely +complicated single language like Japanese) is defined in the +international standard ISO 2022. ISO 2022 will be discussed in more +detail later (*note ISO 2022::), but for now suffice it to say that text +needs control functions (at least spacing), and if escape sequences are +to be used, an escape sequence introducer. It was decided to make all +text streams compatible with ASCII in the sense that the codes 0-31 +(and 128-159) would always be control codes, never graphic characters, +and where defined by the character set the `SPC' character would be +assigned code 32, and `DEL' would be assigned 127. Thus there are 94 +code points remaining if 7 bits are used. This is the reason that most +character sets are defined using position codes in the range 1 through +94. Then ISO 2022 compatible encodings are produced by shifting the +position codes 1 to 94 into character codes 33 to 126, or (if 8 bit +codes are available) into character codes 161 to 254. + + Encodings are classified as either "modal" or "non-modal". In a +"modal encoding", there are multiple states that the encoding can be +in, and the interpretation of the values in the stream depends on the +current global state of the encoding. Special values in the encoding, +called "escape sequences", are used to change the global state. JIS, +for example, is a modal encoding. The bytes `ESC $ B' indicate that, +from then on, bytes are to be interpreted as position codes for JIS X +0208, rather than as ASCII. This effect is cancelled using the bytes +`ESC ( B', which mean "switch from whatever the current state is to +ASCII". To switch to JIS X 0212, the escape sequence `ESC $ ( D'. +(Note that here, as is common, the escape sequences do in fact begin +with `ESC'. This is not necessarily the case, however. Some encodings +use control characters called "locking shifts" (effect persists until +cancelled) to switch character sets.) + + A "non-modal encoding" has no global state that extends past the +character currently being interpreted. EUC, for example, is a +non-modal encoding. Characters in JIS X 0208 are encoded by setting +the high bit of the position codes, and characters in JIS X 0212 are +encoded by doing the same but also prefixing the character with the +byte 0x8F. + + The advantage of a modal encoding is that it is generally more +space-efficient, and is easily extendible because there are essentially +an arbitrary number of escape sequences that can be created. The +disadvantage, however, is that it is much more difficult to work with +if it is not being processed in a sequential manner. In the non-modal +EUC encoding, for example, the byte 0x41 always refers to the letter +`A'; whereas in JIS, it could either be the letter `A', or one of the +two position codes in a JIS X 0208 character, or one of the two +position codes in a JIS X 0212 character. Determining exactly which +one is meant could be difficult and time-consuming if the previous +bytes in the string have not already been processed, or impossible if +they are drawn from an external stream that cannot be rewound. + + Non-modal encodings are further divided into "fixed-width" and +"variable-width" formats. A fixed-width encoding always uses the same +number of words per character, whereas a variable-width encoding does +not. EUC is a good example of a variable-width encoding: one to three +bytes are used per character, depending on the character set. 16-bit +and 32-bit encodings are nearly always fixed-width, and this is in fact +one of the main reasons for using an encoding with a larger word size. +The advantages of fixed-width encodings should be obvious. The +advantages of variable-width encodings are that they are generally more +space-efficient and allow for compatibility with existing 8-bit +encodings such as ASCII. (For example, in Unicode ASCII characters are +simply promoted to a 16-bit representation. That means that every +ASCII character contains a `NUL' byte; evidently all of the standard +string manipulation functions will lose badly in a fixed-width Unicode +environment.) + + The bytes in an 8-bit encoding are often referred to as "octets" +rather than simply as bytes. This terminology dates back to the days +before 8-bit bytes were universal, when some computers had 9-bit bytes, +others had 10-bit bytes, etc. + + +File: lispref.info, Node: Charsets, Next: MULE Characters, Prev: Internationalization Terminology, Up: MULE + +Charsets +======== + + A "charset" in MULE is an object that encapsulates a particular +character set as well as an ordering of those characters.

For example, both the `ascii' and `latin-iso8859-1' + charsets use the registry `"ISO8859-1"'. This field is used to + choose an appropriate font when the user gives a general font + specification such as `-*-courier-medium-r-*-140-*', i.e. a + 14-point upright medium-weight Courier font. + +`dimension' + Number of position codes used to index a character in the + character set. XEmacs/MULE can only handle character sets of + dimension 1 or 2. This property defaults to 1. + +`chars' + Number of characters in each dimension. In XEmacs/MULE, the only + allowed values are 94 or 96. (There are a couple of pre-defined + character sets, such as ASCII, that do not follow this, but you + cannot define new ones like this.) Defaults to 94. Note that if + the dimension is 2, the character set thus described is 94x94 or + 96x96. + +`columns' + Number of columns used to display a character in this charset. + Only used in TTY mode. (Under X, the actual width of a character + can be derived from the font used to display the characters.) If + unspecified, defaults to the dimension. (This is almost always the + correct value, because character sets with dimension 2 are usually + ideograph character sets, which need two columns to display the + intricate ideographs.) + +`direction' + A symbol, either `l2r' (left-to-right) or `r2l' (right-to-left). + Defaults to `l2r'. This specifies the direction that the text + should be displayed in, and will be left-to-right for most + charsets but right-to-left for Hebrew and Arabic. (Right-to-left + display is not currently implemented.) + +`final' + Final byte of the standard ISO 2022 escape sequence designating + this charset. Must be supplied. Each combination of (DIMENSION, + CHARS) defines a separate namespace for final bytes, and each + charset within a particular namespace must have a different final + byte. Note that ISO 2022 restricts the final byte to the range + 0x30 - 0x7E if dimension == 1, and 0x30 - 0x5F if dimension == 2. + Note also that final bytes in the range 0x30 - 0x3F are reserved + for user-defined (not official) character sets. For more + information on ISO 2022, see *Note Coding Systems::. + +`graphic' + 0 (use left half of font on output) or 1 (use right half of font on + output). Defaults to 0. This specifies how to convert the + position codes that index a character in a character set into an + index into the font used to display the character set. With + `graphic' set to 0, position codes 33 through 126 map to font + indices 33 through 126; with it set to 1, position codes 33 + through 126 map to font indices 161 through 254 (i.e. the same + number but with the high bit set). For example, for a font whose + registry is ISO8859-1, the left half of the font (octets 0x20 - + 0x7F) is the `ascii' charset, while the right half (octets 0xA0 - + 0xFF) is the `latin-iso8859-1' charset. + +`ccl-program' + A compiled CCL program used to convert a character in this charset + into an index into the font. This is in addition to the `graphic' + property. If a CCL program is defined, the position codes of a + character will first be processed according to `graphic' and then + passed through the CCL program, with the resulting values used to + index the font. + + This is used, for example, in the Big5 character set (used in + Taiwan). This character set is not ISO-2022-compliant, and its + size (94x157) does not fit within the maximum 96x96 size of + ISO-2022-compliant character sets. As a result, XEmacs/MULE + splits it (in a rather complex fashion, so as to group the most + commonly used characters together) into two charset objects + (`big5-1' and `big5-2'), each of size 94x94, and each charset + object uses a CCL program to convert the modified position codes + back into standard Big5 indices to retrieve a character from a + Big5 font. + + Most of the above properties can only be set when the charset is +initialized, and cannot be changed later. *Note Charset Property +Functions::. + + +File: lispref.info, Node: Basic Charset Functions, Next: Charset Property Functions, Prev: Charset Properties, Up: Charsets + +Basic Charset Functions +----------------------- + + - Function: find-charset charset-or-name + This function retrieves the charset of the given name.

The assignment -operators are `+=', `-=', `*=', `/=', `%=', `&=', `|=', `^=', `<<=', -and `>>=', and they have the same meanings as in C. A "naked integer" -INTEGER is equivalent to a SET statement of the form `(r0 = INTEGER)'. - -I/O statements: -=============== - - The "read" statement takes one or more registers as arguments. It -reads one byte (a C char) from the input into each register in turn. - - The "write" takes several forms. In the form `(write REG ...)' it -takes one or more registers as arguments and writes each in turn to the -output. The integer in a register (interpreted as an Emchar) is -encoded to multibyte form (ie, Bufbytes) and written to the current -output buffer. If it is less than 256, it is written as is. The forms -`(write EXPRESSION)' and `(write INTEGER)' are treated analogously. -The form `(write STRING)' writes the constant string to the output. A -"naked string" `STRING' is equivalent to the statement `(write -STRING)'. The form `(write REG ARRAY)' writes the REGth element of the -ARRAY to the output. - -Conditional statements: -======================= - - The "if" statement takes an EXPRESSION, a CCL BLOCK, and an optional -SECOND CCL BLOCK as arguments. If the EXPRESSION evaluates to -non-zero, the first CCL BLOCK is executed. Otherwise, if there is a -SECOND CCL BLOCK, it is executed. - - The "read-if" variant of the "if" statement takes an EXPRESSION, a -CCL BLOCK, and an optional SECOND CCL BLOCK as arguments. The -EXPRESSION must have the form `(REG OPERATOR OPERAND)' (where OPERAND is -a register or an integer). The `read-if' statement first reads from -the input into the first register operand in the EXPRESSION, then -conditionally executes a CCL block just as the `if' statement does. - - The "branch" statement takes an EXPRESSION and one or more CCL -blocks as arguments. The CCL blocks are treated as a zero-indexed -array, and the `branch' statement uses the EXPRESSION as the index of -the CCL block to execute. Null CCL blocks may be used as no-ops, -continuing execution with the statement following the `branch' -statement in the containing CCL block. Out-of-range values for the -EXPRESSION are also treated as no-ops. - - The "read-branch" variant of the "branch" statement takes an -REGISTER, a CCL BLOCK, and an optional SECOND CCL BLOCK as arguments. -The `read-branch' statement first reads from the input into the -REGISTER, then conditionally executes a CCL block just as the `branch' -statement does. - -Loop control statements: -======================== - - The "loop" statement creates a block with an implied jump from the -end of the block back to its head. The loop is exited on a `break' -statement, and continued without executing the tail by a `repeat' -statement. - - The "break" statement, written `(break)', terminates the current -loop and continues with the next statement in the current block. - - The "repeat" statement has three variants, `repeat', `write-repeat', -and `write-read-repeat'. Each continues the current loop from its -head, possibly after performing I/O. `repeat' takes no arguments and -does no I/O before jumping. `write-repeat' takes a single argument (a -register, an integer, or a string), writes it to the output, then jumps. -`write-read-repeat' takes one or two arguments. The first must be a -register. The second may be an integer or an array; if absent, it is -implicitly set to the first (register) argument. `write-read-repeat' -writes its second argument to the output, then reads from the input -into the register, and finally jumps. See the `write' and `read' -statements for the semantics of the I/O operations for each type of -argument. - -Other control statements: -========================= - - The "call" statement, written `(call CCL-PROGRAM-NAME)', executes a -CCL program as a subroutine. It does not return a value to the caller, -but can modify the register status. - - The "end" statement, written `(end)', terminates the CCL program -successfully, and returns to caller (which may be a CCL program). It -does not alter the status of the registers. - diff --git a/info/lispref.info-45 b/info/lispref.info-45 index f5017ba..e4484ee 100644 --- a/info/lispref.info-45 +++ b/info/lispref.info-45 @@ -50,6 +50,842 @@ may be included in a translation approved by the Free Software Foundation instead of in the original English.  +File: lispref.info, Node: Coding System Properties, Next: Basic Coding System Functions, Prev: EOL Conversion, Up: Coding Systems + +Coding System Properties +------------------------ + +`mnemonic' + String to be displayed in the modeline when this coding system is + active. + +`eol-type' + End-of-line conversion to be used.

In the form `(write REG ...)' it +takes one or more registers as arguments and writes each in turn to the +output.

The forms +`(write EXPRESSION)' and `(write INTEGER)' are treated analogously. +The form `(write STRING)' writes the constant string to the output. A +"naked string" `STRING' is equivalent to the statement `(write +STRING)'. The form `(write REG ARRAY)' writes the REGth element of the +ARRAY to the output. + +Conditional statements: +======================= + + The "if" statement takes an EXPRESSION, a CCL BLOCK, and an optional +SECOND CCL BLOCK as arguments. If the EXPRESSION evaluates to +non-zero, the first CCL BLOCK is executed. Otherwise, if there is a +SECOND CCL BLOCK, it is executed. + + The "read-if" variant of the "if" statement takes an EXPRESSION, a +CCL BLOCK, and an optional SECOND CCL BLOCK as arguments. The +EXPRESSION must have the form `(REG OPERATOR OPERAND)' (where OPERAND is +a register or an integer). The `read-if' statement first reads from +the input into the first register operand in the EXPRESSION, then +conditionally executes a CCL block just as the `if' statement does. + + The "branch" statement takes an EXPRESSION and one or more CCL +blocks as arguments. The CCL blocks are treated as a zero-indexed +array, and the `branch' statement uses the EXPRESSION as the index of +the CCL block to execute. Null CCL blocks may be used as no-ops, +continuing execution with the statement following the `branch' +statement in the containing CCL block. Out-of-range values for the +EXPRESSION are also treated as no-ops. + + The "read-branch" variant of the "branch" statement takes an +REGISTER, a CCL BLOCK, and an optional SECOND CCL BLOCK as arguments. +The `read-branch' statement first reads from the input into the +REGISTER, then conditionally executes a CCL block just as the `branch' +statement does. + +Loop control statements: +======================== + + The "loop" statement creates a block with an implied jump from the +end of the block back to its head. The loop is exited on a `break' +statement, and continued without executing the tail by a `repeat' +statement. + + The "break" statement, written `(break)', terminates the current +loop and continues with the next statement in the current block. + + The "repeat" statement has three variants, `repeat', `write-repeat', +and `write-read-repeat'. Each continues the current loop from its +head, possibly after performing I/O. `repeat' takes no arguments and +does no I/O before jumping. `write-repeat' takes a single argument (a +register, an integer, or a string), writes it to the output, then jumps. +`write-read-repeat' takes one or two arguments. The first must be a +register. The second may be an integer or an array; if absent, it is +implicitly set to the first (register) argument. `write-read-repeat' +writes its second argument to the output, then reads from the input +into the register, and finally jumps. See the `write' and `read' +statements for the semantics of the I/O operations for each type of +argument. + +Other control statements: +========================= + + The "call" statement, written `(call CCL-PROGRAM-NAME)', executes a +CCL program as a subroutine. It does not return a value to the caller, +but can modify the register status. + + The "end" statement, written `(end)', terminates the CCL program +successfully, and returns to caller (which may be a CCL program).

Then take - care to begin the names of all global variables, constants, and - functions with the chosen prefix. This helps avoid name conflicts. - - This recommendation applies even to names for traditional Lisp - primitives that are not primitives in XEmacs Lisp--even to `cadr'. - Believe it or not, there is more than one plausible way to define - `cadr'. Play it safe; append your name prefix to produce a name - like `foo-cadr' or `mylib-cadr' instead. - - If you write a function that you think ought to be added to Emacs - under a certain name, such as `twiddle-files', don't call it by - that name in your program. Call it `mylib-twiddle-files' in your - program, and send mail to `bug-gnu-emacs@prep.ai.mit.edu' - suggesting we add it to Emacs. If and when we do, we can change - the name easily enough. - - If one prefix is insufficient, your package may use two or three - alternative common prefixes, so long as they make sense. - - Separate the prefix from the rest of the symbol name with a hyphen, - `-'. This will be consistent with XEmacs itself and with most - Emacs Lisp programs. - - * It is often useful to put a call to `provide' in each separate - library program, at least if there is more than one entry point to - the program. - - * If a file requires certain other library programs to be loaded - beforehand, then the comments at the beginning of the file should - say so. Also, use `require' to make sure they are loaded. - - * If one file FOO uses a macro defined in another file BAR, FOO - should contain this expression before the first use of the macro: - - (eval-when-compile (require 'BAR)) - - (And BAR should contain `(provide 'BAR)', to make the `require' - work.) This will cause BAR to be loaded when you byte-compile - FOO. Otherwise, you risk compiling FOO without the necessary - macro loaded, and that would produce compiled code that won't work - right. *Note Compiling Macros::. - - Using `eval-when-compile' avoids loading BAR when the compiled - version of FOO is _used_. - - * If you define a major mode, make sure to run a hook variable using - `run-hooks', just as the existing major modes do. *Note Hooks::. - - * If the purpose of a function is to tell you whether a certain - condition is true or false, give the function a name that ends in - `p'. If the name is one word, add just `p'; if the name is - multiple words, add `-p'. Examples are `framep' and - `frame-live-p'. - - * If a user option variable records a true-or-false condition, give - it a name that ends in `-flag'. - - * Please do not define `C-c LETTER' as a key in your major modes. - These sequences are reserved for users; they are the *only* - sequences reserved for users, so we cannot do without them. - - Instead, define sequences consisting of `C-c' followed by a - non-letter. These sequences are reserved for major modes. - - Changing all the major modes in Emacs 18 so they would follow this - convention was a lot of work. Abandoning this convention would - make that work go to waste, and inconvenience users. - - * Sequences consisting of `C-c' followed by `{', `}', `<', `>', `:' - or `;' are also reserved for major modes. - - * Sequences consisting of `C-c' followed by any other punctuation - character are allocated for minor modes. Using them in a major - mode is not absolutely prohibited, but if you do that, the major - mode binding may be shadowed from time to time by minor modes. - - * You should not bind `C-h' following any prefix character (including - `C-c'). If you don't bind `C-h', it is automatically available as - a help character for listing the subcommands of the prefix - character. - - * You should not bind a key sequence ending in except following - another . (That is, it is ok to bind a sequence ending in - ` '.) - - The reason for this rule is that a non-prefix binding for in - any context prevents recognition of escape sequences as function - keys in that context. - - * Applications should not bind mouse events based on button 1 with - the shift key held down. These events include `S-mouse-1', - `M-S-mouse-1', `C-S-mouse-1', and so on. They are reserved for - users. - - * Modes should redefine `mouse-2' as a command to follow some sort of - reference in the text of a buffer, if users usually would not want - to alter the text in that buffer by hand. Modes such as Dired, - Info, Compilation, and Occur redefine it in this way. - - * When a package provides a modification of ordinary Emacs behavior, - it is good to include a command to enable and disable the feature, - Provide a command named `WHATEVER-mode' which turns the feature on - or off, and make it autoload (*note Autoload::). Design the - package so that simply loading it has no visible effect--that - should not enable the feature. Users will request the feature by - invoking the command. - - * It is a bad idea to define aliases for the Emacs primitives. Use - the standard names instead. - - * Redefining an Emacs primitive is an even worse idea. It may do - the right thing for a particular program, but there is no telling - what other programs might break as a result. - - * If a file does replace any of the functions or library programs of - standard XEmacs, prominent comments at the beginning of the file - should say which functions are replaced, and how the behavior of - the replacements differs from that of the originals. - - * Please keep the names of your XEmacs Lisp source files to 13 - characters or less. This way, if the files are compiled, the - compiled files' names will be 14 characters or less, which is - short enough to fit on all kinds of Unix systems. - - * Don't use `next-line' or `previous-line' in programs; nearly - always, `forward-line' is more convenient as well as more - predictable and robust. *Note Text Lines::. - - * Don't call functions that set the mark, unless setting the mark is - one of the intended features of your program. The mark is a - user-level feature, so it is incorrect to change the mark except - to supply a value for the user's benefit. *Note The Mark::. - - In particular, don't use these functions: - - * `beginning-of-buffer', `end-of-buffer' - - * `replace-string', `replace-regexp' - - If you just want to move point, or replace a certain string, - without any of the other features intended for interactive users, - you can replace these functions with one or two lines of simple - Lisp code. - - * Use lists rather than vectors, except when there is a particular - reason to use a vector. Lisp has more facilities for manipulating - lists than for vectors, and working with lists is usually more - convenient. - - Vectors are advantageous for tables that are substantial in size - and are accessed in random order (not searched front to back), - provided there is no need to insert or delete elements (only lists - allow that). - - * The recommended way to print a message in the echo area is with - the `message' function, not `princ'. *Note The Echo Area::. - - * When you encounter an error condition, call the function `error' - (or `signal'). The function `error' does not return. *Note - Signaling Errors::. - - Do not use `message', `throw', `sleep-for', or `beep' to report - errors. - - * An error message should start with a capital letter but should not - end with a period. - - * Try to avoid using recursive edits. Instead, do what the Rmail `e' - command does: use a new local keymap that contains one command - defined to switch back to the old local keymap. Or do what the - `edit-options' command does: switch to another buffer and let the - user switch back at will. *Note Recursive Editing::. - - * In some other systems there is a convention of choosing variable - names that begin and end with `*'. We don't use that convention - in Emacs Lisp, so please don't use it in your programs. (Emacs - uses such names only for program-generated buffers.) The users - will find Emacs more coherent if all libraries use the same - conventions. - - * Indent each function with `C-M-q' (`indent-sexp') using the - default indentation parameters. - - * Don't make a habit of putting close-parentheses on lines by - themselves; Lisp programmers find this disconcerting. Once in a - while, when there is a sequence of many consecutive - close-parentheses, it may make sense to split them in one or two - significant places. - - * Please put a copyright notice on the file if you give copies to - anyone.

See the file - `profile.el' for instructions. - - * Use iteration rather than recursion whenever possible. Function - calls are slow in XEmacs Lisp even when a compiled function is - calling another compiled function. - - * Using the primitive list-searching functions `memq', `member', - `assq', or `assoc' is even faster than explicit iteration. It may - be worth rearranging a data structure so that one of these - primitive search functions can be used. - - * Certain built-in functions are handled specially in byte-compiled - code, avoiding the need for an ordinary function call. It is a - good idea to use these functions rather than alternatives. To see - whether a function is handled specially by the compiler, examine - its `byte-compile' property. If the property is non-`nil', then - the function is handled specially. - - For example, the following input will show you that `aref' is - compiled specially (*note Array Functions::) while `elt' is not - (*note Sequence Functions::): - - (get 'aref 'byte-compile) - => byte-compile-two-args - - (get 'elt 'byte-compile) - => nil - - * If calling a small function accounts for a substantial part of - your program's running time, make the function inline. This - eliminates the function call overhead. Since making a function - inline reduces the flexibility of changing the program, don't do - it unless it gives a noticeable speedup in something slow enough - that users care about the speed. *Note Inline Functions::. - - -File: lispref.info, Node: Documentation Tips, Next: Comment Tips, Prev: Compilation Tips, Up: Tips - -Tips for Documentation Strings -============================== - - Here are some tips for the writing of documentation strings. - - * Every command, function, or variable intended for users to know - about should have a documentation string. - - * An internal variable or subroutine of a Lisp program might as well - have a documentation string. In earlier Emacs versions, you could - save space by using a comment instead of a documentation string, - but that is no longer the case. - - * The first line of the documentation string should consist of one - or two complete sentences that stand on their own as a summary. - `M-x apropos' displays just the first line, and if it doesn't - stand on its own, the result looks bad. In particular, start the - first line with a capital letter and end with a period. - - The documentation string can have additional lines that expand on - the details of how to use the function or variable. The - additional lines should be made up of complete sentences also, but - they may be filled if that looks good. - - * For consistency, phrase the verb in the first sentence of a - documentation string as an infinitive with "to" omitted. For - instance, use "Return the cons of A and B." in preference to - "Returns the cons of A and B." Usually it looks good to do - likewise for the rest of the first paragraph. Subsequent - paragraphs usually look better if they have proper subjects. - - * Write documentation strings in the active voice, not the passive, - and in the present tense, not the future. For instance, use - "Return a list containing A and B." instead of "A list containing - A and B will be returned." - - * Avoid using the word "cause" (or its equivalents) unnecessarily. - Instead of, "Cause Emacs to display text in boldface," write just - "Display text in boldface." - - * Do not start or end a documentation string with whitespace. - - * Format the documentation string so that it fits in an Emacs window - on an 80-column screen. It is a good idea for most lines to be no - wider than 60 characters. The first line can be wider if - necessary to fit the information that ought to be there. - - However, rather than simply filling the entire documentation - string, you can make it much more readable by choosing line breaks - with care. Use blank lines between topics if the documentation - string is long. - - * *Do not* indent subsequent lines of a documentation string so that - the text is lined up in the source code with the text of the first - line. This looks nice in the source code, but looks bizarre when - users view the documentation. Remember that the indentation - before the starting double-quote is not part of the string! - - * A variable's documentation string should start with `*' if the - variable is one that users would often want to set interactively. - If the value is a long list, or a function, or if the variable - would be set only in init files, then don't start the - documentation string with `*'. *Note Defining Variables::. - - * The documentation string for a variable that is a yes-or-no flag - should start with words such as "Non-nil means...", to make it - clear that all non-`nil' values are equivalent and indicate - explicitly what `nil' and non-`nil' mean. - - * When a function's documentation string mentions the value of an - argument of the function, use the argument name in capital letters - as if it were a name for that value. Thus, the documentation - string of the function `/' refers to its second argument as - `DIVISOR', because the actual argument name is `divisor'. - - Also use all caps for meta-syntactic variables, such as when you - show the decomposition of a list or vector into subunits, some of - which may vary. - - * When a documentation string refers to a Lisp symbol, write it as it - would be printed (which usually means in lower case), with - single-quotes around it. For example: `lambda'. There are two - exceptions: write t and nil without single-quotes. (In this - manual, we normally do use single-quotes for those symbols.) - - * Don't write key sequences directly in documentation strings. - Instead, use the `\\[...]' construct to stand for them. For - example, instead of writing `C-f', write `\\[forward-char]'. When - Emacs displays the documentation string, it substitutes whatever - key is currently bound to `forward-char'. (This is normally `C-f', - but it may be some other character if the user has moved key - bindings.) *Note Keys in Documentation::. - - * In documentation strings for a major mode, you will want to refer - to the key bindings of that mode's local map, rather than global - ones. Therefore, use the construct `\\<...>' once in the - documentation string to specify which key map to use. Do this - before the first use of `\\[...]'. The text inside the `\\<...>' - should be the name of the variable containing the local keymap for - the major mode. - - It is not practical to use `\\[...]' very many times, because - display of the documentation string will become slow. So use this - to describe the most important commands in your major mode, and - then use `\\{...}' to display the rest of the mode's keymap. - - -File: lispref.info, Node: Comment Tips, Next: Library Headers, Prev: Documentation Tips, Up: Tips - -Tips on Writing Comments -======================== - - We recommend these conventions for where to put comments and how to -indent them: - -`;' - Comments that start with a single semicolon, `;', should all be - aligned to the same column on the right of the source code.

Here is a table of the conventional -possibilities for HEADER-NAME: - -`Author' - This line states the name and net address of at least the principal - author of the library. - - If there are multiple authors, you can list them on continuation - lines led by `;;' and a tab character, like this: - - ;; Author: Ashwin Ram - ;; Dave Sill - ;; Dave Brennan - ;; Eric Raymond - -`Maintainer' - This line should contain a single name/address as in the Author - line, or an address only, or the string `FSF'. If there is no - maintainer line, the person(s) in the Author field are presumed to - be the maintainers. The example above is mildly bogus because the - maintainer line is redundant. - - The idea behind the `Author' and `Maintainer' lines is to make - possible a Lisp function to "send mail to the maintainer" without - having to mine the name out by hand. - - Be sure to surround the network address with `<...>' if you - include the person's full name as well as the network address. - -`Created' - This optional line gives the original creation date of the file. - For historical interest only. - -`Version' - If you wish to record version numbers for the individual Lisp - program, put them in this line. - -`Adapted-By' - In this header line, place the name of the person who adapted the - library for installation (to make it fit the style conventions, for - example). - -`Keywords' - This line lists keywords for the `finder-by-keyword' help command. - This field is important; it's how people will find your package - when they're looking for things by topic area. To separate the - keywords, you can use spaces, commas, or both. - - Just about every Lisp library ought to have the `Author' and -`Keywords' header comment lines. Use the others if they are -appropriate. You can also put in header lines with other header -names--they have no standard meanings, so they can't do any harm. - - We use additional stylized comments to subdivide the contents of the -library file. Here is a table of them: - -`;;; Commentary:' - This begins introductory comments that explain how the library - works. It should come right after the copying permissions. - -`;;; Change log:' - This begins change log information stored in the library file (if - you store the change history there). For most of the Lisp files - distributed with XEmacs, the change history is kept in the file - `ChangeLog' and not in the source file at all; these files do not - have a `;;; Change log:' line. - -`;;; Code:' - This begins the actual code of the program. - -`;;; FILENAME ends here' - This is the "footer line"; it appears at the very end of the file. - Its purpose is to enable people to detect truncated versions of - the file from the lack of a footer line. - - -File: lispref.info, Node: Building XEmacs and Object Allocation, Next: Standard Errors, Prev: Tips, Up: Top - -Building XEmacs; Allocation of Objects -************************************** - - This chapter describes how the runnable XEmacs executable is dumped -with the preloaded Lisp libraries in it and how storage is allocated. - - There is an entire separate document, the `XEmacs Internals Manual', -devoted to the internals of XEmacs from the perspective of the C -programmer.

You don't have to know this material to build and install -XEmacs, since the makefiles do all these things automatically. This -information is pertinent to XEmacs maintenance. - - The `XEmacs Internals Manual' contains more information about this. - - Compilation of the C source files in the `src' directory produces an -executable file called `temacs', also called a "bare impure XEmacs". -It contains the XEmacs Lisp interpreter and I/O routines, but not the -editing commands. - - Before XEmacs is actually usable, a number of Lisp files need to be -loaded. These define all the editing commands, plus most of the startup -code and many very basic Lisp primitives. This is accomplished by -loading the file `loadup.el', which in turn loads all of the other -standardly-loaded Lisp files. - - It takes a substantial time to load the standard Lisp files. -Luckily, you don't have to do this each time you run XEmacs; `temacs' -can dump out an executable program called `xemacs' that has these files -preloaded. `xemacs' starts more quickly because it does not need to -load the files. This is the XEmacs executable that is normally -installed. - - To create `xemacs', use the command `temacs -batch -l loadup dump'. -The purpose of `-batch' here is to tell `temacs' to run in -non-interactive, command-line mode. (`temacs' can _only_ run in this -fashion. Part of the code required to initialize frames and faces is -in Lisp, and must be loaded before XEmacs is able to create any frames.) -The argument `dump' tells `loadup.el' to dump a new executable named -`xemacs'. - - The dumping process is highly system-specific, and some operating -systems don't support dumping. On those systems, you must start XEmacs -with the `temacs -batch -l loadup run-temacs' command each time you use -it. This takes a substantial time, but since you need to start Emacs -once a day at most--or once a week if you never log out--the extra time -is not too severe a problem. (In older versions of Emacs, you started -Emacs from `temacs' using `temacs -l loadup'.) - - You are free to start XEmacs directly from `temacs' if you want, -even if there is already a dumped `xemacs'. Normally you wouldn't want -to do that; but the Makefiles do this when you rebuild XEmacs using -`make all-elc', which builds XEmacs and simultaneously compiles any -out-of-date Lisp files. (You need `xemacs' in order to compile Lisp -files. However, you also need the compiled Lisp files in order to dump -out `xemacs'. If both of these are missing or corrupted, you are out -of luck unless you're able to bootstrap `xemacs' from `temacs'. Note -that `make all-elc' actually loads the alternative loadup file -`loadup-el.el', which works like `loadup.el' but disables the -pure-copying process and forces XEmacs to ignore any compiled Lisp -files even if they exist.) - - You can specify additional files to preload by writing a library -named `site-load.el' that loads them. You may need to increase the -value of `PURESIZE', in `src/puresize.h', to make room for the -additional files. You should _not_ modify this file directly, however; -instead, use the `--puresize' configuration option. (If you run out of -pure space while dumping `xemacs', you will be told how much pure space -you actually will need.) However, the advantage of preloading -additional files decreases as machines get faster. On modern machines, -it is often not advisable, especially if the Lisp code is on a file -system local to the machine running XEmacs. - - You can specify other Lisp expressions to execute just before dumping -by putting them in a library named `site-init.el'. However, if they -might alter the behavior that users expect from an ordinary unmodified -XEmacs, it is better to put them in `default.el', so that users can -override them if they wish. *Note Start-up Summary::. - - Before `loadup.el' dumps the new executable, it finds the -documentation strings for primitive and preloaded functions (and -variables) in the file where they are stored, by calling -`Snarf-documentation' (*note Accessing Documentation::). These strings -were moved out of the `xemacs' executable to make it smaller. *Note -Documentation Basics::. - - - Function: dump-emacs to-file from-file - This function dumps the current state of XEmacs into an executable - file TO-FILE. It takes symbols from FROM-FILE (this is normally - the executable file `temacs'). - - If you use this function in an XEmacs that was already dumped, you - must set `command-line-processed' to `nil' first for good results. - *Note Command Line Arguments::. - - - Function: run-emacs-from-temacs &rest args - This is the function that implements the `run-temacs' command-line - argument. It is called from `loadup.el' as appropriate. You - should most emphatically _not_ call this yourself; it will - reinitialize your XEmacs process and you'll be sorry. - - - Command: emacs-version - This function returns a string describing the version of XEmacs - that is running. It is useful to include this string in bug - reports. - - (emacs-version) - => "XEmacs 20.1 [Lucid] (i586-unknown-linux2.0.29) - of Mon Apr 7 1997 on altair.xemacs.org" - - Called interactively, the function prints the same information in - the echo area. - - - Variable: emacs-build-time - The value of this variable is the time at which XEmacs was built - at the local site. - - emacs-build-time "Mon Apr 7 20:28:52 1997" - => - - - Variable: emacs-version - The value of this variable is the version of Emacs being run. It - is a string, e.g. `"20.1 XEmacs Lucid"'. - - The following two variables did not exist before FSF GNU Emacs -version 19.23 and XEmacs version 19.10, which reduces their usefulness -at present, but we hope they will be convenient in the future. - - - Variable: emacs-major-version - The major version number of Emacs, as an integer. For XEmacs - version 20.1, the value is 20. - - - Variable: emacs-minor-version - The minor version number of Emacs, as an integer. For XEmacs - version 20.1, the value is 1. - - -File: lispref.info, Node: Pure Storage, Next: Garbage Collection, Prev: Building XEmacs, Up: Building XEmacs and Object Allocation - -Pure Storage -============ - - XEmacs Lisp uses two kinds of storage for user-created Lisp objects: -"normal storage" and "pure storage". Normal storage is where all the -new data created during an XEmacs session is kept; see the following -section for information on normal storage. Pure storage is used for -certain data in the preloaded standard Lisp files--data that should -never change during actual use of XEmacs. - - Pure storage is allocated only while `temacs' is loading the -standard preloaded Lisp libraries. In the file `xemacs', it is marked -as read-only (on operating systems that permit this), so that the -memory space can be shared by all the XEmacs jobs running on the machine -at once. Pure storage is not expandable; a fixed amount is allocated -when XEmacs is compiled, and if that is not sufficient for the preloaded -libraries, `temacs' aborts with an error message. If that happens, you -must increase the compilation parameter `PURESIZE' using the -`--puresize' option to `configure'. This normally won't happen unless -you try to preload additional libraries or add features to the standard -ones. - - - Function: purecopy object - This function makes a copy of OBJECT in pure storage and returns - it. It copies strings by simply making a new string with the same - characters in pure storage. It recursively copies the contents of - vectors and cons cells. It does not make copies of other objects - such as symbols, but just returns them unchanged. It signals an - error if asked to copy markers. - - This function is a no-op except while XEmacs is being built and - dumped; it is usually called only in the file - `xemacs/lisp/prim/loaddefs.el', but a few packages call it just in - case you decide to preload them. - - - Variable: pure-bytes-used - The value of this variable is the number of bytes of pure storage - allocated so far. Typically, in a dumped XEmacs, this number is - very close to the total amount of pure storage available--if it - were not, we would preallocate less. - - - Variable: purify-flag - This variable determines whether `defun' should make a copy of the - function definition in pure storage. If it is non-`nil', then the - function definition is copied into pure storage. - - This flag is `t' while loading all of the basic functions for - building XEmacs initially (allowing those functions to be sharable - and non-collectible). Dumping XEmacs as an executable always - writes `nil' in this variable, regardless of the value it actually - has before and after dumping. - - You should not change this flag in a running XEmacs. - diff --git a/info/lispref.info-46 b/info/lispref.info-46 index a1767fa..2e76962 100644 --- a/info/lispref.info-46 +++ b/info/lispref.info-46 @@ -50,6 +50,763 @@ may be included in a translation approved by the Free Software Foundation instead of in the original English.  +File: lispref.info, Node: Style Tips, Next: Compilation Tips, Up: Tips + +Writing Clean Lisp Programs +=========================== + + Here are some tips for avoiding common errors in writing Lisp code +intended for widespread use: + + * Since all global variables share the same name space, and all + functions share another name space, you should choose a short word + to distinguish your program from other Lisp programs. Then take + care to begin the names of all global variables, constants, and + functions with the chosen prefix. This helps avoid name conflicts. + + This recommendation applies even to names for traditional Lisp + primitives that are not primitives in XEmacs Lisp--even to `cadr'. + Believe it or not, there is more than one plausible way to define + `cadr'. Play it safe; append your name prefix to produce a name + like `foo-cadr' or `mylib-cadr' instead. + + If you write a function that you think ought to be added to Emacs + under a certain name, such as `twiddle-files', don't call it by + that name in your program. Call it `mylib-twiddle-files' in your + program, and send mail to `bug-gnu-emacs@prep.ai.mit.edu' + suggesting we add it to Emacs. If and when we do, we can change + the name easily enough. + + If one prefix is insufficient, your package may use two or three + alternative common prefixes, so long as they make sense. + + Separate the prefix from the rest of the symbol name with a hyphen, + `-'. This will be consistent with XEmacs itself and with most + Emacs Lisp programs. + + * It is often useful to put a call to `provide' in each separate + library program, at least if there is more than one entry point to + the program. + + * If a file requires certain other library programs to be loaded + beforehand, then the comments at the beginning of the file should + say so. Also, use `require' to make sure they are loaded. + + * If one file FOO uses a macro defined in another file BAR, FOO + should contain this expression before the first use of the macro: + + (eval-when-compile (require 'BAR)) + + (And BAR should contain `(provide 'BAR)', to make the `require' + work.) This will cause BAR to be loaded when you byte-compile + FOO. Otherwise, you risk compiling FOO without the necessary + macro loaded, and that would produce compiled code that won't work + right. *Note Compiling Macros::. + + Using `eval-when-compile' avoids loading BAR when the compiled + version of FOO is _used_. + + * If you define a major mode, make sure to run a hook variable using + `run-hooks', just as the existing major modes do. *Note Hooks::. + + * If the purpose of a function is to tell you whether a certain + condition is true or false, give the function a name that ends in + `p'. If the name is one word, add just `p'; if the name is + multiple words, add `-p'. Examples are `framep' and + `frame-live-p'. + + * If a user option variable records a true-or-false condition, give + it a name that ends in `-flag'. + + * Please do not define `C-c LETTER' as a key in your major modes. + These sequences are reserved for users; they are the *only* + sequences reserved for users, so we cannot do without them. + + Instead, define sequences consisting of `C-c' followed by a + non-letter. These sequences are reserved for major modes. + + Changing all the major modes in Emacs 18 so they would follow this + convention was a lot of work. Abandoning this convention would + make that work go to waste, and inconvenience users. + + * Sequences consisting of `C-c' followed by `{', `}', `<', `>', `:' + or `;' are also reserved for major modes. + + * Sequences consisting of `C-c' followed by any other punctuation + character are allocated for minor modes. Using them in a major + mode is not absolutely prohibited, but if you do that, the major + mode binding may be shadowed from time to time by minor modes. + + * You should not bind `C-h' following any prefix character (including + `C-c'). If you don't bind `C-h', it is automatically available as + a help character for listing the subcommands of the prefix + character. + + * You should not bind a key sequence ending in except following + another . (That is, it is ok to bind a sequence ending in + ` '.) + + The reason for this rule is that a non-prefix binding for in + any context prevents recognition of escape sequences as function + keys in that context. + + * Applications should not bind mouse events based on button 1 with + the shift key held down. These events include `S-mouse-1', + `M-S-mouse-1', `C-S-mouse-1', and so on. They are reserved for + users. + + * Modes should redefine `mouse-2' as a command to follow some sort of + reference in the text of a buffer, if users usually would not want + to alter the text in that buffer by hand. Modes such as Dired, + Info, Compilation, and Occur redefine it in this way. + + * When a package provides a modification of ordinary Emacs behavior, + it is good to include a command to enable and disable the feature, + Provide a command named `WHATEVER-mode' which turns the feature on + or off, and make it autoload (*note Autoload::). Design the + package so that simply loading it has no visible effect--that + should not enable the feature. Users will request the feature by + invoking the command. + + * It is a bad idea to define aliases for the Emacs primitives. Use + the standard names instead. + + * Redefining an Emacs primitive is an even worse idea. It may do + the right thing for a particular program, but there is no telling + what other programs might break as a result. + + * If a file does replace any of the functions or library programs of + standard XEmacs, prominent comments at the beginning of the file + should say which functions are replaced, and how the behavior of + the replacements differs from that of the originals. + + * Please keep the names of your XEmacs Lisp source files to 13 + characters or less. This way, if the files are compiled, the + compiled files' names will be 14 characters or less, which is + short enough to fit on all kinds of Unix systems. + + * Don't use `next-line' or `previous-line' in programs; nearly + always, `forward-line' is more convenient as well as more + predictable and robust. *Note Text Lines::. + + * Don't call functions that set the mark, unless setting the mark is + one of the intended features of your program. The mark is a + user-level feature, so it is incorrect to change the mark except + to supply a value for the user's benefit. *Note The Mark::. + + In particular, don't use these functions: + + * `beginning-of-buffer', `end-of-buffer' + + * `replace-string', `replace-regexp' + + If you just want to move point, or replace a certain string, + without any of the other features intended for interactive users, + you can replace these functions with one or two lines of simple + Lisp code. + + * Use lists rather than vectors, except when there is a particular + reason to use a vector. Lisp has more facilities for manipulating + lists than for vectors, and working with lists is usually more + convenient. + + Vectors are advantageous for tables that are substantial in size + and are accessed in random order (not searched front to back), + provided there is no need to insert or delete elements (only lists + allow that). + + * The recommended way to print a message in the echo area is with + the `message' function, not `princ'. *Note The Echo Area::. + + * When you encounter an error condition, call the function `error' + (or `signal'). The function `error' does not return. *Note + Signaling Errors::. + + Do not use `message', `throw', `sleep-for', or `beep' to report + errors. + + * An error message should start with a capital letter but should not + end with a period. + + * Try to avoid using recursive edits. Instead, do what the Rmail `e' + command does: use a new local keymap that contains one command + defined to switch back to the old local keymap. Or do what the + `edit-options' command does: switch to another buffer and let the + user switch back at will. *Note Recursive Editing::. + + * In some other systems there is a convention of choosing variable + names that begin and end with `*'. We don't use that convention + in Emacs Lisp, so please don't use it in your programs. (Emacs + uses such names only for program-generated buffers.) The users + will find Emacs more coherent if all libraries use the same + conventions. + + * Indent each function with `C-M-q' (`indent-sexp') using the + default indentation parameters. + + * Don't make a habit of putting close-parentheses on lines by + themselves; Lisp programmers find this disconcerting. Once in a + while, when there is a sequence of many consecutive + close-parentheses, it may make sense to split them in one or two + significant places. + + * Please put a copyright notice on the file if you give copies to + anyone.

See the file + `profile.el' for instructions. + + * Use iteration rather than recursion whenever possible. Function + calls are slow in XEmacs Lisp even when a compiled function is + calling another compiled function. + + * Using the primitive list-searching functions `memq', `member', + `assq', or `assoc' is even faster than explicit iteration. It may + be worth rearranging a data structure so that one of these + primitive search functions can be used. + + * Certain built-in functions are handled specially in byte-compiled + code, avoiding the need for an ordinary function call. It is a + good idea to use these functions rather than alternatives. To see + whether a function is handled specially by the compiler, examine + its `byte-compile' property. If the property is non-`nil', then + the function is handled specially. + + For example, the following input will show you that `aref' is + compiled specially (*note Array Functions::) while `elt' is not + (*note Sequence Functions::): + + (get 'aref 'byte-compile) + => byte-compile-two-args + + (get 'elt 'byte-compile) + => nil + + * If calling a small function accounts for a substantial part of + your program's running time, make the function inline. This + eliminates the function call overhead. Since making a function + inline reduces the flexibility of changing the program, don't do + it unless it gives a noticeable speedup in something slow enough + that users care about the speed. *Note Inline Functions::. + + +File: lispref.info, Node: Documentation Tips, Next: Comment Tips, Prev: Compilation Tips, Up: Tips + +Tips for Documentation Strings +============================== + + Here are some tips for the writing of documentation strings. + + * Every command, function, or variable intended for users to know + about should have a documentation string. + + * An internal variable or subroutine of a Lisp program might as well + have a documentation string. In earlier Emacs versions, you could + save space by using a comment instead of a documentation string, + but that is no longer the case. + + * The first line of the documentation string should consist of one + or two complete sentences that stand on their own as a summary. + `M-x apropos' displays just the first line, and if it doesn't + stand on its own, the result looks bad. In particular, start the + first line with a capital letter and end with a period. + + The documentation string can have additional lines that expand on + the details of how to use the function or variable. The + additional lines should be made up of complete sentences also, but + they may be filled if that looks good. + + * For consistency, phrase the verb in the first sentence of a + documentation string as an infinitive with "to" omitted. For + instance, use "Return the cons of A and B." in preference to + "Returns the cons of A and B." Usually it looks good to do + likewise for the rest of the first paragraph. Subsequent + paragraphs usually look better if they have proper subjects. + + * Write documentation strings in the active voice, not the passive, + and in the present tense, not the future. For instance, use + "Return a list containing A and B." instead of "A list containing + A and B will be returned." + + * Avoid using the word "cause" (or its equivalents) unnecessarily. + Instead of, "Cause Emacs to display text in boldface," write just + "Display text in boldface." + + * Do not start or end a documentation string with whitespace. + + * Format the documentation string so that it fits in an Emacs window + on an 80-column screen. It is a good idea for most lines to be no + wider than 60 characters. The first line can be wider if + necessary to fit the information that ought to be there. + + However, rather than simply filling the entire documentation + string, you can make it much more readable by choosing line breaks + with care. Use blank lines between topics if the documentation + string is long. + + * *Do not* indent subsequent lines of a documentation string so that + the text is lined up in the source code with the text of the first + line. This looks nice in the source code, but looks bizarre when + users view the documentation. Remember that the indentation + before the starting double-quote is not part of the string! + + * A variable's documentation string should start with `*' if the + variable is one that users would often want to set interactively. + If the value is a long list, or a function, or if the variable + would be set only in init files, then don't start the + documentation string with `*'. *Note Defining Variables::. + + * The documentation string for a variable that is a yes-or-no flag + should start with words such as "Non-nil means...", to make it + clear that all non-`nil' values are equivalent and indicate + explicitly what `nil' and non-`nil' mean. + + * When a function's documentation string mentions the value of an + argument of the function, use the argument name in capital letters + as if it were a name for that value. Thus, the documentation + string of the function `/' refers to its second argument as + `DIVISOR', because the actual argument name is `divisor'. + + Also use all caps for meta-syntactic variables, such as when you + show the decomposition of a list or vector into subunits, some of + which may vary. + + * When a documentation string refers to a Lisp symbol, write it as it + would be printed (which usually means in lower case), with + single-quotes around it. For example: `lambda'. There are two + exceptions: write t and nil without single-quotes. (In this + manual, we normally do use single-quotes for those symbols.) + + * Don't write key sequences directly in documentation strings. + Instead, use the `\\[...]' construct to stand for them. For + example, instead of writing `C-f', write `\\[forward-char]'. When + Emacs displays the documentation string, it substitutes whatever + key is currently bound to `forward-char'. (This is normally `C-f', + but it may be some other character if the user has moved key + bindings.) *Note Keys in Documentation::. + + * In documentation strings for a major mode, you will want to refer + to the key bindings of that mode's local map, rather than global + ones. Therefore, use the construct `\\<...>' once in the + documentation string to specify which key map to use. Do this + before the first use of `\\[...]'. The text inside the `\\<...>' + should be the name of the variable containing the local keymap for + the major mode. + + It is not practical to use `\\[...]' very many times, because + display of the documentation string will become slow. So use this + to describe the most important commands in your major mode, and + then use `\\{...}' to display the rest of the mode's keymap. + + +File: lispref.info, Node: Comment Tips, Next: Library Headers, Prev: Documentation Tips, Up: Tips + +Tips on Writing Comments +======================== + + We recommend these conventions for where to put comments and how to +indent them: + +`;' + Comments that start with a single semicolon, `;', should all be + aligned to the same column on the right of the source code. Such + comments usually explain how the code on the same line does its + job. In Lisp mode and related modes, the `M-;' + (`indent-for-comment') command automatically inserts such a `;' in + the right place, or aligns such a comment if it is already present. + + This and following examples are taken from the Emacs sources. + + (setq base-version-list ; there was a base + (assoc (substring fn 0 start-vn) ; version to which + file-version-assoc-list)) ; this looks like + ; a subversion + +`;;' + Comments that start with two semicolons, `;;', should be aligned to + the same level of indentation as the code.

For example: + + (prog1 (setq auto-fill-function + ... + ... + ;; update modeline + (redraw-modeline))) + + Every function that has no documentation string (because it is use + only internally within the package it belongs to), should have + instead a two-semicolon comment right before the function, + explaining what the function does and how to call it properly. + Explain precisely what each argument means and how the function + interprets its possible values. + +`;;;' + Comments that start with three semicolons, `;;;', should start at + the left margin. Such comments are used outside function + definitions to make general statements explaining the design + principles of the program. For example: + + ;;; This Lisp code is run in XEmacs + ;;; when it is to operate as a server + ;;; for other processes. + + Another use for triple-semicolon comments is for commenting out + lines within a function.

If there is no + maintainer line, the person(s) in the Author field are presumed to + be the maintainers. The example above is mildly bogus because the + maintainer line is redundant. + + The idea behind the `Author' and `Maintainer' lines is to make + possible a Lisp function to "send mail to the maintainer" without + having to mine the name out by hand. + + Be sure to surround the network address with `<...>' if you + include the person's full name as well as the network address. + +`Created' + This optional line gives the original creation date of the file. + For historical interest only. + +`Version' + If you wish to record version numbers for the individual Lisp + program, put them in this line. + +`Adapted-By' + In this header line, place the name of the person who adapted the + library for installation (to make it fit the style conventions, for + example). + +`Keywords' + This line lists keywords for the `finder-by-keyword' help command. + This field is important; it's how people will find your package + when they're looking for things by topic area. To separate the + keywords, you can use spaces, commas, or both. + + Just about every Lisp library ought to have the `Author' and +`Keywords' header comment lines. Use the others if they are +appropriate. You can also put in header lines with other header +names--they have no standard meanings, so they can't do any harm. + + We use additional stylized comments to subdivide the contents of the +library file.

You don't have to know this material to build and install +XEmacs, since the makefiles do all these things automatically. This +information is pertinent to XEmacs maintenance. + + The `XEmacs Internals Manual' contains more information about this. + + Compilation of the C source files in the `src' directory produces an +executable file called `temacs', also called a "bare impure XEmacs". +It contains the XEmacs Lisp interpreter and I/O routines, but not the +editing commands. + + Before XEmacs is actually usable, a number of Lisp files need to be +loaded. These define all the editing commands, plus most of the startup +code and many very basic Lisp primitives. This is accomplished by +loading the file `loadup.el', which in turn loads all of the other +standardly-loaded Lisp files. + + It takes a substantial time to load the standard Lisp files. +Luckily, you don't have to do this each time you run XEmacs; `temacs' +can dump out an executable program called `xemacs' that has these files +preloaded. `xemacs' starts more quickly because it does not need to +load the files. This is the XEmacs executable that is normally +installed. + + To create `xemacs', use the command `temacs -batch -l loadup dump'. +The purpose of `-batch' here is to tell `temacs' to run in +non-interactive, command-line mode. (`temacs' can _only_ run in this +fashion. Part of the code required to initialize frames and faces is +in Lisp, and must be loaded before XEmacs is able to create any frames.) +The argument `dump' tells `loadup.el' to dump a new executable named +`xemacs'. + + The dumping process is highly system-specific, and some operating +systems don't support dumping. On those systems, you must start XEmacs +with the `temacs -batch -l loadup run-temacs' command each time you use +it. This takes a substantial time, but since you need to start Emacs +once a day at most--or once a week if you never log out--the extra time +is not too severe a problem. (In older versions of Emacs, you started +Emacs from `temacs' using `temacs -l loadup'.) + + You are free to start XEmacs directly from `temacs' if you want, +even if there is already a dumped `xemacs'. Normally you wouldn't want +to do that; but the Makefiles do this when you rebuild XEmacs using +`make all-elc', which builds XEmacs and simultaneously compiles any +out-of-date Lisp files. (You need `xemacs' in order to compile Lisp +files. However, you also need the compiled Lisp files in order to dump +out `xemacs'. If both of these are missing or corrupted, you are out +of luck unless you're able to bootstrap `xemacs' from `temacs'. Note +that `make all-elc' actually loads the alternative loadup file +`loadup-el.el', which works like `loadup.el' but disables the +pure-copying process and forces XEmacs to ignore any compiled Lisp +files even if they exist.) + + You can specify additional files to preload by writing a library +named `site-load.el' that loads them. You may need to increase the +value of `PURESIZE', in `src/puresize.h', to make room for the +additional files. You should _not_ modify this file directly, however; +instead, use the `--puresize' configuration option. (If you run out of +pure space while dumping `xemacs', you will be told how much pure space +you actually will need.) However, the advantage of preloading +additional files decreases as machines get faster. On modern machines, +it is often not advisable, especially if the Lisp code is on a file +system local to the machine running XEmacs. + + You can specify other Lisp expressions to execute just before dumping +by putting them in a library named `site-init.el'. However, if they +might alter the behavior that users expect from an ordinary unmodified +XEmacs, it is better to put them in `default.el', so that users can +override them if they wish. *Note Start-up Summary::. + + Before `loadup.el' dumps the new executable, it finds the +documentation strings for primitive and preloaded functions (and +variables) in the file where they are stored, by calling +`Snarf-documentation' (*note Accessing Documentation::). These strings +were moved out of the `xemacs' executable to make it smaller. *Note +Documentation Basics::. + + - Function: dump-emacs to-file from-file + This function dumps the current state of XEmacs into an executable + file TO-FILE. It takes symbols from FROM-FILE (this is normally + the executable file `temacs'). + + If you use this function in an XEmacs that was already dumped, you + must set `command-line-processed' to `nil' first for good results. + *Note Command Line Arguments::. + + - Function: run-emacs-from-temacs &rest args + This is the function that implements the `run-temacs' command-line + argument. It is called from `loadup.el' as appropriate. You + should most emphatically _not_ call this yourself; it will + reinitialize your XEmacs process and you'll be sorry. + + - Command: emacs-version &optional arg + This function returns a string describing the version of XEmacs + that is running. It is useful to include this string in bug + reports. + + When called interactively with a prefix argument, insert string at + point. Don't use this function in programs to choose actions + according to the system configuration; look at + `system-configuration' instead. + + (emacs-version) + => "XEmacs 20.1 [Lucid] (i586-unknown-linux2.0.29) + of Mon Apr 7 1997 on altair.xemacs.org" + + Called interactively, the function prints the same information in + the echo area. + + - Variable: emacs-build-time + The value of this variable is the time at which XEmacs was built + at the local site. + + emacs-build-time "Mon Apr 7 20:28:52 1997" + => + + - Variable: emacs-version + The value of this variable is the version of Emacs being run.

Normal storage is where all the +new data created during an XEmacs session is kept; see the following +section for information on normal storage. Pure storage is used for +certain data in the preloaded standard Lisp files--data that should +never change during actual use of XEmacs. + + Pure storage is allocated only while `temacs' is loading the +standard preloaded Lisp libraries. In the file `xemacs', it is marked +as read-only (on operating systems that permit this), so that the +memory space can be shared by all the XEmacs jobs running on the machine +at once. Pure storage is not expandable; a fixed amount is allocated +when XEmacs is compiled, and if that is not sufficient for the preloaded +libraries, `temacs' aborts with an error message. If that happens, you +must increase the compilation parameter `PURESIZE' using the +`--puresize' option to `configure'. This normally won't happen unless +you try to preload additional libraries or add features to the standard +ones. + + - Function: purecopy object + This function makes a copy of OBJECT in pure storage and returns + it. It copies strings by simply making a new string with the same + characters in pure storage. It recursively copies the contents of + vectors and cons cells. It does not make copies of other objects + such as symbols, but just returns them unchanged. It signals an + error if asked to copy markers. + + This function is a no-op except while XEmacs is being built and + dumped; it is usually called only in the file + `xemacs/lisp/prim/loaddefs.el', but a few packages call it just in + case you decide to preload them. + + - Variable: pure-bytes-used + The value of this variable is the number of bytes of pure storage + allocated so far. Typically, in a dumped XEmacs, this number is + very close to the total amount of pure storage available--if it + were not, we would preallocate less. + + - Variable: purify-flag + This variable determines whether `defun' should make a copy of the + function definition in pure storage. If it is non-`nil', then the + function definition is copied into pure storage. + + This flag is `t' while loading all of the basic functions for + building XEmacs initially (allowing those functions to be sharable + and non-collectible). Dumping XEmacs as an executable always + writes `nil' in this variable, regardless of the value it actually + has before and after dumping. + + You should not change this flag in a running XEmacs. + + File: lispref.info, Node: Garbage Collection, Prev: Pure Storage, Up: Building XEmacs and Object Allocation Garbage Collection @@ -230,14 +987,6 @@ using `malloc' and `free'. not apply if XEmacs was configured with `--debug'.

These -entries are based on Lisp expressions (sexps) that Emacs evaluates as -it scans the diary file. Instead of a date, a sexp entry contains `%%' -followed by a Lisp expression which must begin and end with -parentheses. The Lisp expression determines which dates the entry -applies to. - - Calendar mode provides commands to insert certain commonly used sexp -entries: - -`i a' - Add an anniversary diary entry for the selected date - (`insert-anniversary-diary-entry'). - -`i b' - Add a block diary entry for the current region - (`insert-block-diary-entry'). - -`i c' - Add a cyclic diary entry starting at the date - (`insert-cyclic-diary-entry'). - - If you want to make a diary entry that applies to the anniversary of -a specific date, move point to that date and use the `i a' command. -This displays the end of your diary file in another window and inserts -the anniversary description; you can then type the rest of the diary -entry. The entry looks like this: - - The effect of `i a' is to add a `diary-anniversary' sexp to your -diary file. You can also add one manually, for instance: - - %%(diary-anniversary 10 31 1948) Arthur's birthday - -This entry applies to October 31 in any year after 1948; `10 31 1948' -specifies the date. (If you are using the European calendar style, the -month and day are interchanged.) The reason this expression requires a -beginning year is that advanced diary functions can use it to calculate -the number of elapsed years. - - A "block" diary entry applies to a specified range of consecutive -dates. Here is a block diary entry that applies to all dates from June -24, 1990 through July 10, 1990: - - %%(diary-block 6 24 1990 7 10 1990) Vacation - -The `6 24 1990' indicates the starting date and the `7 10 1990' -indicates the stopping date.

This command displays -the end of your diary file in another window and inserts the block -description; you can then type the diary entry. - - "Cyclic" diary entries repeat after a fixed interval of days. To -create one, select the starting date and use the `i c' command. The -command prompts for the length of interval, then inserts the entry, -which looks like this: - - %%(diary-cyclic 50 3 1 1990) Renew medication - -This entry applies to March 1, 1990 and every 50th day following; `3 1 -1990' specifies the starting date.

These +entries are based on Lisp expressions (sexps) that Emacs evaluates as +it scans the diary file. Instead of a date, a sexp entry contains `%%' +followed by a Lisp expression which must begin and end with +parentheses.

The entry looks like this: + + The effect of `i a' is to add a `diary-anniversary' sexp to your +diary file. You can also add one manually, for instance: + + %%(diary-anniversary 10 31 1948) Arthur's birthday + +This entry applies to October 31 in any year after 1948; `10 31 1948' +specifies the date. (If you are using the European calendar style, the +month and day are interchanged.) The reason this expression requires a +beginning year is that advanced diary functions can use it to calculate +the number of elapsed years. + + A "block" diary entry applies to a specified range of consecutive +dates. Here is a block diary entry that applies to all dates from June +24, 1990 through July 10, 1990: + + %%(diary-block 6 24 1990 7 10 1990) Vacation + +The `6 24 1990' indicates the starting date and the `7 10 1990' +indicates the stopping date.

(It is often best to put it on a page by itself.) The local +variables list starts with a line containing the string `Local +Variables:', and ends with a line containing the string `End:'. In +between come the variable names and values, one set per line, as +`VARIABLE: VALUE'. The VALUEs are not evaluated; they are used +literally. + + The line which starts the local variables list does not have to say +just `Local Variables:'. If there is other text before `Local +Variables:', that text is called the "prefix", and if there is other +text after, that is called the "suffix". If a prefix or suffix are +present, each entry in the local variables list should have the prefix +before it and the suffix after it. This includes the `End:' line. The +prefix and suffix are included to disguise the local variables list as +a comment so the compiler or text formatter will ignore it. If you do +not need to disguise the local variables list as a comment in this way, +there is no need to include a prefix or a suffix. + + Two "variable" names are special in a local variables list: a value +for the variable `mode' sets the major mode, and a value for the +variable `eval' is simply evaluated as an expression and the value is +ignored. These are not real variables; setting them in any other +context does not have the same effect. If `mode' is used in a local +variables list, it should be the first entry in the list. + + Here is an example of a local variables list: + ;;; Local Variables: *** + ;;; mode:lisp *** + ;;; comment-column:0 *** + ;;; comment-start: ";;; " *** + ;;; comment-end:"***" *** + ;;; End: *** + + Note that the prefix is `;;; ' and the suffix is ` ***'. Note also +that comments in the file begin with and end with the same strings. +Presumably the file contains code in a language which is enough like +Lisp for Lisp mode to be useful but in which comments start and end +differently. The prefix and suffix are used in the local variables +list to make the list look like several lines of comments when the +compiler or interpreter for that language reads the file. + + The start of the local variables list must be no more than 3000 +characters from the end of the file, and must be in the last page if the +file is divided into pages. Otherwise, Emacs will not notice it is +there. The purpose is twofold: a stray `Local Variables:' not in the +last page does not confuse Emacs, and Emacs never needs to search a +long file that contains no page markers and has no local variables list. + + You may be tempted to turn on Auto Fill mode with a local variable +list.

However, the detailed - calculations of the various locations needed significant - overhaul. - - At the point of the old .bss, the file offsets and the memory - addresses do distinct, slightly snaky things: - - offset of .bss is meaningless and unpredictable - addr of .bss is meaningful - alignment of .bss is important to addr, so there may be a small - gap in address range before start of bss - offset of next section is rounded up modulo 0x1000 - the hole so-introduced is zero-filled, so it can be mapped in as - the first partial-page of bss (the rest of the bss is mapped from - /dev/zero) - I suppose you could view this not as a hole, but as the beginning - of the bss, actually present in the file. But you should not - push that worldview too far, as the linker still knows that the - "offset" claimed for the bss is unused, and seems not always - careful about setting it. - - We are doing all our tricks at this same rather complicated - location (isn't life fun?): - - insert a new data section to contain now-initialized old bss and - heap - define a zero-length bss just so there is one - - The offset of the new data section is dictated by its current - address (which, of course, we want also to be its addr): the - loader maps in the whole file region containing old data, rodata, - got, and new data as a single mapped segment, starting at the - address of the first chunk; the rest have to be laid out in the - file such that the map into the right spots. That is: - - offset(newdata) == - addrInRunningMemory(newdata)-aIRM(olddata) - + offset(oldData) - - This would not necessarily match the oldbss offset, even if it - were carefully calculated! We must compute this. - - The linker that built temacs has also already arranged that - olddata is properly page-aligned (not necessarily beginning on a - page, but rather that a page's worth of the low bits of addr and - offset match). We preserve this. - - addr(bss) is alignment-constrained from the end of the new data. - Since we base endof(newdata) on sbrk(), we have a page boundary - (in both offset and addr) and meet any alignment constraint, - needing no alignment adjustment of this location and no - mini-hole. Or, if you like, we've allowed sbrk() to "compute" - the mini-hole size for us. - - That puts newbss beginning on a page boundary, both in offset and - addr. (offset(bss) is still meaningless, but what the heck, - we'll fix it up.) - - Since newbss has zero length, and its offset (however - meaningless) is page aligned, we place the next section exactly - there, with no hole needed to restore page alignment. - - So, the shift for all sections beyond the playing field is: - - new_bss_addr - roundup(old_bss_addr,0x1000) - - */ - /* Still more mods...
