Announcing XEmacs 20.2
XEmacs 20.2 is now available. This is a version of GNU Emacs derived
from Emacs version 19 from the Free Software Foundation.
This is a continuation of the Internationalization development path
started with XEmacs 20.0 and is not yet considered an official upgrade
path from XEmacs 19.15. It is a major upgrade from 20.0, containing
many bug fixes and enhancements. If you are using XEmacs 20.0 in any
flavor (including off of the Sun CD) you should consider upgrading to
The primary new feature in XEmacs 20.2 is additional support for MULE
MUlti-Lingual extensions for Emacs. It has only been seriously tested
in a Japanese locale, and no doubt many problems still remain. The
support for ISO-Latin-1 and Japanese is fairly strong, so we're
releasing it now. MULE support comes at a price -- about a 30%
slowdown from 19.15. We're working on making things faster, but it's
taking time. Currently, 19.15 and 20.2 compiled without MULE
(20.2-latin-1) are faster than 19.14.
In short, if you don't need the internationalization features and
you're not interested in participating in the upgrade path of XEmacs
until the new code stabilizes you should use 19.15. If you like the
idea of running the latest code, but don't want to take the
performance hit of MULE, don't need to have non-Latin-1 language
support, and are willing to put up with the occasional incompatibility
caused by the change to the character type, then you should use
XEmacs-v20-latin-1. If you wish the whole `v20 experience', then you
should use XEmacs-v20-MULE.
You can get XEmacs via anonymous FTP from FTP.XEMACS.ORG (188.8.131.52).
or from the following mirrors:
It may take a few days for the files to propagate to all of the mirrors.
(Mirror sites are encouraged to automatically check ftp.xemacs.org)
The complete list of mirror sites, the current FAQ, and several other XEmacs
related items can be found at the XEmacs World Wide Web page:

They should become available over the next couple of weeks given sufficient
The complete source distribution. This file is about 20.5 megabytes.
When unpacked, the source distribution will take up about 78 megs.
You will need another 26 megs or so to compile it.
Don't forget to set "binary" mode when transferring these files. Unpack them
with some variation of the command
"gunzip -c xemacs-20.0.tar.gz | tar -pvxf -".
There is a newsgroup for discussing XEmacs.
comp.emacs.xemacs: For reporting all bugs in XEmacs, including bugs
in the compilation and installation procedures.
Also for random questions and conversation about
There is also a mailing list, xem...@xemacs.org. This mailing list is
bidirectionally gatewayed with the newsgroup comp.emacs.xemacs. To be added
or removed from this mailing list, send mail to xemacs-requ...@xemacs.org.
(Send all administrative requests, and only administrative requests, to this
Please use the newsgroups instead of mailing directly to the
maintainers, you are likelier to get a better response that way.
Crashes should be reported by using the `M-x send-pr' command built
into XEmacs. This sends the problem report off to a Gnats-based bug
tracking system. If this fails for any reason you can still report
the crash to cras...@xemacs.org, but the report won't be tracked.
When reporting a crash, please read carefully the information in part
II of the XEmacs FAQ so that you can include enough information in
your report to get the problem resolved. In particular, if you are
experiencing coredumps, it is vital that you compile XEmacs with the
`-g' compile flag so the stack back trace is meaningful.
Do not send messages about problems with XEmacs to the GNU Emacs
newsgroups and mailing lists (help-gnu-em...@prep.ai.mit.edu,
bug-gnu-em...@prep.ai.mit.edu, gnu.emacs.help, gnu.emacs.bug, et cetera)
unless you are sure that the problem you are reporting is a problem with
both versions of Emacs.
The following is an excerpt from the NEWS file:
* Changes in XEmacs 20.2
** Why XEmacs 20.1 is called 20.2
Testing of XEmacs 20.1 revealed a number of showstopping bugs at the
very final moment. Instead of confusing the version numbers further,
the `20.1' designation was abandoned, and the release was renamed to
** Delete/backspace keysyms have been separated
The Delete and Backspace keysyms are now no longer identical. A better
version of delbackspace.el has been added called delbs.el.
** XEmacs 20.0 MULE API supported for backwards compatibilty
XEmacs 20.2 primarily supports the MULE 3 API. It now also supports
the XEmacs 20.0 MULE API.
** The logo has been changed, and the default background color is
now a shade of gray instead of the eye-burning white.
The sample .Xdefaults and .emacs files contain examples of how to
revert to the old background color.
** Default modeline colors are now less of a color-salad.
** The `C-z' key now iconifies only the current X frame. You can use
`C-x C-z' to get the old behavior.
On the tty frames `C-z' behaves as before.
** The command `display-time' now draws a pretty image in the modeline
when new mail arrives. It also supports balloon-help messages.
** Various commands that were previously disabled are now enabled, like
eval-expression (`M-:') and upcase-region (`C-x C-u')/downcase-region
** It is now possible to customize the functions called by XEmacs toolbar.
Type `M-x customize RET toolbar RET' to customize it. Customizations
include the choice of functions for the buttons to invoke, as well as
a wide choice of mailers and newsreaders to invoked by the respective
** `temp-buffer-shrink-to-fit' now defaults to nil.
There are unresolved issues regarding this feature, which is why the
XEmacs developers decided to disable it by default.
** `ps-print-color-p' now defaults to nil.
This is because the new default background color is non-white. The
`Printing Options' in the `Options' menu now include an item that
enables color printing, and sets the white background.
** `line-number-mode' should be used to get line numbers in the
modeline, and `column-number-mode' to get column numbers. Line
numbers now number from 1 by default.
** font-lock-mode will now correctly fontify `int a, b, c;'
expressions in C mode.
** The blinking cursor is always "on" during movement.
** The XEmacs build process has been changed to make site
administration easier. See lisp/site-load.el for details.
** Numerous causes of crashes have been fixed. XEmacs should now be
even more stable than before.
** configure no longer defaults to using --with-xim=motif if Motif libraries
There are many bugs in the Xlib XIM support in X11R6.3.
** A number of new packages are added, and many packages were
** Gnus-5.4.52, courtesy of Lars Magne Ingebrigtsen
** Custom 1.86, courtesy of Per Abrahamsen
The Customize library enables Emacs Lisp programmers to specify types
of their variables, so that the users can customize them.
Invoke the customizations buffer using the menus (Customize is at the
top of the Options menu), or using commands `M-x customize',
`M-x customize-variable' and `M-x customize-face'. Customize can save
the changed settings to your `.emacs' file.
Customize is now the preferred way to change XEmacs settings. Tens of
packages have been converted to take advantage of the Customize
features, including Gnus, Message, Supercite, Psgml, Comint, W3,
cc-mode (and many other programming language modes), ispell.el,
ps-print.el, id-select.el, most of the programming language modes, and
many many more.
See the "Lisp Changes" section later for a short description of why
and how to add custom support to your Lisp packages. Custom is also
documented in the XEmacs info manuals.
** W3-3.0.86, courtesy of William Perry
Version 3 of Emacs/W3, the Emacs World Wide Web browser, has been
included. It is significantly faster than any of the previous
versions, and contains numerous new features.
** AUCTeX-9.7k, courtesy of Per Abrahamsen
AUC TeX is a comprehensive customizable integrated environment for
writing input files for LaTeX using Emacs.
AUC TeX lets you run TeX/LaTeX and other LaTeX-related tools, such as
a output filters or post processor from inside Emacs. Especially
`running LaTeX' is interesting, as AUC TeX lets you browse through the
errors TeX reported, while it moves the cursor directly to the
reported error, and displays some documentation for that particular
error. This will even work when the document is spread over several
AUC TeX automatically indents your `LaTeX-source', not only as you
write it -- you can also let it indent and format an entire document.
It has a special outline feature, which can greatly help you `getting
an overview' of a document.
Apart from these special features, AUC TeX provides an large range of
handy Emacs macros, which in several different ways can help you write
your LaTeX documents fast and painless.
** redo.el-1.01, courtesy of Kyle Jones
redo.el is a package that implements true redo mechanism in XEmacs
buffers. Once you load it from your `.emacs', you can bind the `redo'
command to a convenient key to use it.
Emacs' normal undo system allows you to undo an arbitrary number of
buffer changes. These undos are recorded as ordinary buffer changes
themselves. So when you break the chain of undos by issuing some
other command, you can then undo all the undos. The chain of recorded
buffer modifications therefore grows without bound, truncated only at
garbage collection time.
The redo/undo system is different in two ways:
*** The undo/redo command chain is only broken by a buffer modification.
You can move around the buffer or switch buffers and still come back
and do more undos or redos.
*** The `redo' command rescinds the most recent undo without
recording the change as a _new_ buffer change.
It completely reverses the effect of the undo, which includes making
the chain of buffer modification records shorter by one, to counteract
the effect of the undo command making the record list longer by one.
** edmacro.el-3.10, courtesy of Dave Gillespie, ported to XEmacs by
Edmacro is a utility that provides easy editing of keyboard macros.
Originally written by Dave Gillespie, it has been mostly rewritten by
Hrvoje Niksic, in order to make it distinguish characters and integer,
as well as to adapt it to XEmacs keysyms.
Press `C-x C-k' to invoke the `edit-kbd-macro' command that lets you
edit old as well as define new keyboard macros. You can also edit the
last 100 keystrokes and insert them into a macro to be bound to a key
or named as a command. The recorded/edited macros can be dumped to
** xmine.el-1.8, courtesy of Jens Lautenbacher
XEmacs now includes a minesweeper game with a full-featured graphics
and mouse interface. Invoke with `M-x xmine'.
** efs-1.15-x5 courtesy of Andy Norman and Michael Sperber
EFS is now integrated with XEmacs, and replaces the old ange-ftp. It
has many more features, including info documentation, support for many
different FTP servers, and integration with dired.
