XEmacs FAQ

Introduction
************

   This is the guide to the XEmacs Frequently Asked Questions list--a
compendium of questions and answers pertaining to one of the finest
programs ever written.  It is much more than just a Text Editor.

   This FAQ is freely redistributable.  I take no liability for the
correctness and safety of any procedures or advice given here.  This
FAQ is distributed in the hope that it will be useful, but WITHOUT ANY

   If you have a Web browser, the official hypertext version is at

   This version is somewhat nicer than the unofficial hypertext versions
that are archived at Utrecht, Oxford, Smart Pages, and other FAQ
archives.

*******************************

   Learning XEmacs is a lifelong activity.  Even people who have used
Emacs for years keep discovering new features.  Therefore this document
cannot be complete.  Instead it is aimed at the person who is either
considering XEmacs for their own use, or has just obtained it and is
wondering what to do next.  It is also useful as a reference to
available resources.

   The previous maintainer of the FAQ was Anthony Rossini
<rossini@biostat.washington.edu>, who started it, after getting tired
of hearing JWZ complain about repeatedly having to answer questions.
Ben Wing <ben@xemacs.org> and Chuck Thompson <cthomp@xemacs.org>, the
principal authors of XEmacs, then took over and Ben did a massive
update reorganizing the whole thing.  At which point Anthony took back
over, but then had to give it up again.  Some of the other contributors
to this FAQ are listed later in this document.

   The previous version was converted to hypertext format, and edited by
Steven L. Baur <steve@xemacs.org>.  It was converted back to texinfo by
Hrvoje Niksic <hniksic@xemacs.org>.  The FAQ was then maintained by
Andreas Kaempf <andreas@sccon.com>, who passed it on to ChristianNyb/o.

   If you notice any errors or items which should be added or amended to
this FAQ please send email to Sandra Wambold <faq@xemacs.org>.  Include
`XEmacs FAQ' on the Subject: line.

Q1.0.1: What is XEmacs?
-----------------------

   An alternative to GNU Emacs, originally based on an early alpha
version of FSF's version 19, and has diverged quite a bit since then.
XEmacs was known as Lucid Emacs through version 19.10.  Almost all
features of GNU Emacs are supported in XEmacs.  The maintainers of
XEmacs actively track changes to GNU Emacs while also working to add
new features.

Q1.0.2: What is the current version of XEmacs?
----------------------------------------------

   XEmacs 21.1.8 is the current stable version of XEmacs.

   XEmacs 20.4 is a minor upgrade from 20.3, containing many bugfixes.
It was released in February 1998.

   XEmacs 19.16 was the last release of v19, released in November, 1997,
which was also the last version without international language support.

Q1.0.4: Why Another Version of Emacs?
-------------------------------------

   For a detailed description of the differences between GNU Emacs and
XEmacs and a detailed history of XEmacs, check out the
     NEWS file (http://www.xemacs.org/About/XEmacsVsGNUemacs.html)

   However, here is a list of some of the reasons why we think you might
consider using it:

   * It looks nicer.

   * The XEmacs maintainers are generally more receptive to suggestions
     than the GNU Emacs maintainers.

   * Many more bundled packages than GNU Emacs

   * Binaries are available for many common operating systems.

   * Face support on TTY's.

   * A built-in toolbar.

   * Better Motif compliance.

   * Some internationalization support (including full MULE support, if
     compiled with it.)

   * Variable-width fonts.

   * Variable-height lines.

   * Marginal annotations.

   * ToolTalk support.

   * XEmacs can be used as an Xt widget, and can be embedded within
     another application.

   * Horizontal and vertical scrollbars (using real toolkit scrollbars).

   * Better APIs (and performance) for attaching fonts, colors, and
     other properties to text.

   * The ability to embed arbitrary graphics in a buffer.

   * Completely compatible (at the C level) with the Xt-based toolkits.

   * First production Web Browser supporting Style Sheets.

Q1.0.5: Why Haven't XEmacs and GNU Emacs Merged?
------------------------------------------------

   There are currently irreconcilable differences in the views about
technical, programming, design and organizational matters between RMS
and the XEmacs development team which provide little hope for a merge to
take place in the short-term future.

   If you have a comment to add regarding the merge, it is a good idea
to avoid posting to the newsgroups,  because of the very heated
flamewars that often result.  Mail your questions to
<xemacs-beta@xemacs.org> and <bug-gnu-emacs@prep.ai.mit.edu>.

1.3: Internationalization
=========================

Q1.3.1: What is the status of XEmacs v20?
-----------------------------------------

   XEmacs v20 is the version of XEmacs that includes MULE
(Asian-language) support.  XEmacs 20.0 was released in February 1997,
followed by XEmacs 20.2 in May, XEmacs 20.3 in November and XEmacs 20.4
in February 1998.  When compiled without MULE support, 20.4 is
approximately as stable as 19.16, and probably faster (due to
additional optimization work.)

   As of XEmacs 20.3, version 20 is _the_ supported version of XEmacs.
This means that 19.16 will optionally receive stability fixes (if any),
but that all the real development work will be done on the v20 tree.

   The incompatible changes in XEmacs 20 include the additional
byte-codes, new primitive data types (`character', `char-table', and
`range-table').  This means that the character-integer equivalence
inherent to all the previous Emacs and XEmacs releases no longer
applies.

   However, to avoid breaking old code, many functions that should
normally accept characters work with integers, and vice versa.  For more
information, see the Lisp reference manual.  Here is a relevant excerpt,
for your convenience.

       In XEmacs version 19, and in all versions of FSF GNU Emacs, a
     "character" in XEmacs Lisp is nothing more than an integer.  This
     is yet another holdover from XEmacs Lisp's derivation from
     vintage-1980 Lisps; modern versions of Lisp consider this
     equivalence a bad idea, and have separate character types.  In
     XEmacs version 20, the modern convention is followed, and
     characters are their own primitive types. (This change was
     necessary in order for MULE, i.e. Asian-language, support to be
     correctly implemented.)

     Even in XEmacs version 20, remnants of the equivalence between
     characters and integers still exist; this is termed the "char-int
     confoundance disease".  In particular, many functions such as `eq',
     `equal', and `memq' have equivalent functions (`old-eq',
     `old-equal', `old-memq', etc.) that pretend like characters are
     integers are the same.  Byte code compiled under any version 19
     Emacs will have all such functions mapped to their `old-'
     equivalents when the byte code is read into XEmacs 20.  This is to
     preserve compatibility - Emacs 19 converts all constant characters
     to the equivalent integer during byte-compilation, and thus there
     is no other way to preserve byte-code compatibility even if the
     code has specifically been written with the distinction between
     characters and integers in mind.

     Every character has an equivalent integer, called the "character
     code".  For example, the character `A' is represented as the
     integer 65, following the standard ASCII representation of
     characters.  If XEmacs was not compiled with MULE support, the
     range of this integer will always be 0 to 255 - eight bits, or one
     byte. (Integers outside this range are accepted but silently
     truncated; however, you should most decidedly _not_ rely on this,
     because it will not work under XEmacs with MULE support.)  When
     MULE support is present, the range of character codes is much
     larger. (Currently, 19 bits are used.)

     FSF GNU Emacs uses kludgy character codes above 255 to represent
     keyboard input of ASCII characters in combination with certain
     modifiers.  XEmacs does not use this (a more general mechanism is
     used that does not distinguish between ASCII keys and other keys),
     so you will never find character codes above 255 in a non-MULE
     XEmacs.

     Individual characters are not often used in programs.  It is far
     more common to work with _strings_, which are sequences composed of
     characters.

<xemacs-mule@xemacs.org> mailing list.  Especially needed are people

Q1.3.4: Can XEmacs messages come out in a different language?
-------------------------------------------------------------

   The message-catalog support has mostly been written but doesn't
currently work.  The first release of XEmacs 20 will _not_ support it.
However, menubar localization _does_ work, even in 19.14.  To enable
it, add to your `Emacs' file entries like this:

     Emacs*XlwMenu.resourceLabels:                      True
     Emacs*XlwMenu.file.labelString:                    Fichier
     Emacs*XlwMenu.openInOtherWindow.labelString:       In anderem Fenster offnen

   The name of the resource is derived from the non-localized entry by
removing punctuation and capitalizing as above.

Q1.3.5: Please explain the various input methods in MULE/XEmacs 20.0
--------------------------------------------------------------------

   MORIOKA Tomohiko <morioka@jaist.ac.jp> writes:

     Original Mule supports the following input methods: Wnn4, Wnn6,
     Canna, SJ3 and XIM. Interfaces for Wnn and SJ3 uses the `egg' user
     interface. Interface for Canna does not use `egg'. I don't know
     about XIM. It is to support ATOK, of course, it may work for
     another servers.

     Wnn supports Japanese, Chinese and Korean. It is made by OMRON and
     Kyôto university. It is a powerful and complex system.  Wnn4 is
     free and Wnn6 is not free.

     Canna supports only Japanese. It is made by NEC. It is a simple and
     powerful system. Canna uses only grammar (Wnn uses grammar and
     probability between words), so I think Wnn is cleverer than Canna,
     however Canna users made a good grammar and dictionary.  So for
     standard modern Japanese, Canna seems cleverer than Wnn4. In
     addition, the UNIX version of Canna is free (now there is a
     Microsoft Windows version).

     SJ3 supports only Japanese. It is made by Sony.  XIM supports was
     made to use ATOK (a major input method in personal computer
     world).  XIM is the standard for accessing input methods bundled
     in Japanese versions of Solaris.  (XEmacs 20 will support XIM
     input).

     Egg consists of following parts:

       1. Input character Translation System (ITS) layer.  It
          translates ASCII inputs to Kana/PinYin/Hangul characters.

       2. Kana/PinYin/Hangul to Kanji transfer layer.  It is interface
          layer for network Kana-Kanji server (Wnn and Sj3).

     These input methods are modal, namely there are mode, alphabet
     mode and Kana-Kanji transfer mode.  However there are mode-less
     input methods for Egg and Canna.  `Boiled-egg' is a mode-less
     input method running on Egg.  For Canna, `canna.el' has a tiny
     boiled-egg like command, `(canna-boil)', and there are some
     boiled-egg like utilities.  In addition, it was planned to make an
     abstraction for all transfer type input methods.  However authors
     of input methods are busy, so maybe this plan is stopped.  Perhaps
     after Mule merged GNU Emacs will be released, it will be continued.

Q1.3.6: How do I portably code for MULE/XEmacs 20?
--------------------------------------------------

   MORIOKA Tomohiko <morioka@jaist.ac.jp> writes:

     MULE and XEmacs are quite different. So the application
     implementor must write separate code for these mule variants.

     MULE and the next version of Emacs are similar but the symbols are
     very different--requiring separate code as well.

     Namely we must support 3 kinds of mule variants and 4 or 5 or 6
     kinds of emacs variants... (;_;) I'm shocked, so I wrote a wrapper
     package called `emu' to provide a common interface.

     I have the following suggestions about dealing with mule variants:

        * `(featurep 'mule)' `t' on all mule variants

        * `(boundp 'MULE)' is `t' on only MULE.  Maybe the next version
          of Emacs will not have this symbol.

        * MULE has a variable `mule-version'.  Perhaps the next version
          of Emacs will have this variable as well.

     Following is a sample to distinguish mule variants:

          (if (featurep 'mule)
              (cond ((boundp 'MULE)
                     ;; for original Mule
                     )
                  ((string-match "XEmacs" emacs-version)
                   ;; for XEmacs with Mule
                   )
                  (t
                   ;; for next version of Emacs

   Starting with 19.14, you may bring the `sample.emacs' into an XEmacs
buffer by selecting `Help->Sample .emacs' from the menubar.  To
determine the location of the `etc' directory type the command `C-h v
data-directory <RET>'.

Q1.4.2: Can I use the same `.emacs' with the other Emacs?
---------------------------------------------------------

   Yes.  The sample `.emacs' included in the XEmacs distribution will
show you how to handle different versions and flavors of Emacs.

Q1.4.3: Any good tutorials around?
----------------------------------

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

Q1.4.4: May I see an example of a useful XEmacs Lisp function?
--------------------------------------------------------------

   The following function does a little bit of everything useful.  It
does something with the prefix argument, it examines the text around the
cursor, and it's interactive so it may be bound to a key.  It inserts
copies of the current word the cursor is sitting on at the cursor.  If
you give it a prefix argument: `C-u 3 M-x double-word' then it will
insert 3 copies.

     (defun double-word (count)
       "Insert a copy of the current word underneath the cursor"
       (interactive "*p")
       (let (here there string)
         (save-excursion
           (forward-word -1)
           (setq here (point))
           (forward-word 1)
           (setq there (point))
           (setq string (buffer-substring here there)))
         (while (>= count 1)
           (insert string)
           (decf count))))

   The best way to see what is going on here is to let XEmacs tell you.
Put the code into an XEmacs buffer, and do a `C-h f' with the cursor
sitting just to the right of the function you want explained.  Eg.  move
the cursor to the SPACE between `interactive' and `"*p"' and hit `C-h
f' to see what the function `interactive' does.  Doing this will tell
you that the `*' requires a writable buffer, and `p' converts the
prefix argument to a number, and `interactive' allows you to execute
the command with `M-x'.

Q1.4.5: And how do I bind it to a key?
--------------------------------------

   To bind to a key do:

     (global-set-key "\C-cd" 'double-word)

   Or interactively, `M-x global-set-key' and follow the prompts.

Q1.4.6: What's the difference between a macro and a function?
-------------------------------------------------------------

   Quoting from the Lisp Reference (a.k.a "Lispref") Manual:

   "Macros" enable you to define new control constructs and other
language features.  A macro is defined much like a function, but instead
of telling how to compute a value, it tells how to compute another Lisp
expression which will in turn compute the value.  We call this
expression the "expansion" of the macro.

   Macros can do this because they operate on the unevaluated
expressions for the arguments, not on the argument values as functions
do.  They can therefore construct an expansion containing these
argument expressions or parts of them.

   Do not confuse the two terms with "keyboard macros", which are
another matter, entirely.  A keyboard macro is a key bound to several
other keys.  Refer to manual for details.

2.0: Installation
=================

Q2.0.1: Running XEmacs without installing
-----------------------------------------

   The `INSTALL' file says that up to 108 MB of space is needed
temporarily during installation!  How can I just try it out?

   XEmacs will run in place without requiring installation and copying
of the Lisp directories, and without having to specify a special
build-time flag.  It's the copying of the Lisp directories that
requires so much space.  XEmacs is largely written in Lisp.

   A good method is to make a shell alias for xemacs:

     alias xemacs=/i/xemacs-20.2/src/xemacs

   (You will obviously use whatever directory you downloaded the source
tree to instead of `/i/xemacs-20.2').

   This will let you run XEmacs without massive copying.
