NAME
xemacs - Emacs: The Next Generation
SYNOPSIS
xemacs [ command-line switches ] [
files ... ]
DESCRIPTION
XEmacs is a version of Emacs,
compatible with and containing many improvements over GNU
Emacs, written by Richard Stallman of the Free Software
Foundation. It was originally based on an early release of GNU
Emacs Version 19, and has tracked subsequent releases of
GNU Emacs as they have become available.
The primary documentation of XEmacs is in the XEmacs
Reference Manual, which you can read on-line using Info,
a subsystem of XEmacs. Please look there for complete and
up-to-date documentation. Complete documentation on using Emacs
Lisp is available on-line through the XEmacs Lisp
Programmer's Manual. Both manuals also can be printed
out nicely using the TeX formatting package.
The user functionality of XEmacs encompasses everything
other Emacs editors do, and it is easily extensible since
its editing commands are written in Lisp.
XEmacs has an extensive interactive help facility, but
the facility assumes that you know how to manipulate XEmacs
windows and buffers. CTRL-h enters the Help facility. Help Tutorial
(CTRL-h t) requests an interactive tutorial which can teach
beginners the fundamentals of XEmacs in a few minutes. Help
Apropos (CTRL-h a) helps you find a command given its
functionality, Help Key Binding (CTRL-h k) describes a given key
sequence's effect, and Help Function (CTRL-h f) describes a given
Lisp function specified by name. You can also look up key sequences
in the XEmacs Reference Manual using Lookup Key Binding
(CTRL-h CTRL-k), and look up Lisp functions in the XEmacs Lisp
Programmer's Manual using Lookup Function (CTRL-h CTRL-f). All
of these help functions, and more, are available on the Help menu
if you are using a window system.
XEmacs has extensive GUI (graphical user interface)
support when running under a window system such as X,
including multiple frames (top-level windows), a menubar, a
toolbar, horizontal and vertical scrollbars, dialog boxes, and
extensive mouse support.
XEmacs has full support for multiple fonts and colors,
variable-width fonts, and variable-height lines, and allows for
pixmaps to be inserted into a buffer. (This is used in the W3
web-browsing package and in some of the debugger and outlining
interfaces, among other things.)
XEmacs's Undo can undo several steps of modification to
your buffers, so it is easy to recover from editing mistakes.
XEmacs's many special packages handle mail reading (VM,
MH-E and RMail) and sending (Mail), Usenet news reading and posting
(GNUS), World Wide Web browsing (W3), specialized modes for editing
source code in all common programming languages, syntax
highlighting for many languages (Font-Lock), compiling (Compile),
running subshells within XEmacs windows (Shell), outline
editing (Outline), running a Lisp read-eval-print loop
(Lisp-Interaction-Mode), and automated psychotherapy (Doctor).
There is an extensive reference manual, but users of other
Emacsen should have little trouble adapting even without a copy.
Users new to Emacs will be able to use basic features fairly
rapidly by studying the tutorial and using the self-documentation
features.
XEmacs Options
XEmacs accepts all standard X Toolkit command line options when
run in an X Windows environment. In addition, the following options
are accepted (when options imply a sequence of actions to perform,
they are performed in the order encountered):
- -t file
- Use specified file as the terminal instead of using
stdin/stdout. This implies -nw.
- -batch
- Edit in batch mode. The editor will send messages to stdout.
You must use the -l, -f, and -eval options to
specify files to execute and functions to call.
- -nw
- Inhibit the use of any window-system-specific display code: use
the current TTY.
- -debug-init
- Enter the debugger if an error occurs loading the init file.
- -unmapped
- Do not map the initial frame.
- -no-site-file
- Do not load the site-specific init file (site-start.el).
- -q, -no-init-file
- Do not load an init file.
- -no-early-packages
- Do not process the early packages.
- -vanilla
- Load no extra files at startup. Equivalent to the combination
of -q , -no-site-file , and -no-early-packages
.
- -u user, -user user
- Load user's init file.
- file
- Edit file.
- +number
- Go to the line specified by number (do not insert a
space between the "+" sign and the number).
- -help
- Print a help message and exit.
- -V, -version,
- Print the version number and exit.
- -f function, -funcall function
- Execute the lisp function function.
- -l file, -load file
- Load the Lisp code in the file file.
- -eval form
- Evaluate the Lisp form form.
- -i file, -insert file
- Insert file into the current buffer.
- -kill
- Exit XEmacs (useful with -batch).
Using XEmacs with X Windows
XEmacs has been tailored to work well with the X window
system. If you run XEmacs from under X windows, it will
create its own X window to display in.
XEmacs can be started with the following standard X
options:
- -visual <visualname><bitdepth>
- Select the visual that XEmacs will attempt to use.
<visualname> should be one of the strings
"StaticColor", "TrueColor", "GrayScale", "PseudoColor" or
"DirectColor", and <bitdepth> should be the number of
bits per pixel (example, "-visual TrueColor24" for a 24bit
TrueColor visual) See X(1) for more
information.
- -privateColormap
- Require XEmacs to create and use a private colormap for
display. This will keep XEmacs from taking colors from the default
colormap and keeping them from other clients, at the cost of
causing annoying flicker when the focus changes. Use this option
only if your X server does not support 24 bit visuals.
- -geometry ##x##+##+##
- Specify the geometry of the initial window. The ##'s represent
a number; the four numbers are width (characters), height
(characters), X offset (pixels), and Y offset (pixels),
respectively. Partial specifications of the form ##x## or
+##+## are also allowed. (The geometry specification is in
the standard X format; see X(1) for more
information.)
- -iconic
- Specifies that the initial window should initially appear
iconified.
- -name name
- Specifies the program name which should be used when looking up
defaults in the user's X resources.
- -title title, -T title, -wn
- -title title, -T title, -wn
title
title
- Specifies the title which should be assigned to the
- Specifies the title which should be assigned to the
XEmacs window.
- -d displayname, -display
displayname
- Create the XEmacs window on the display specified by
displayname. Must be the first option specified in the
command line.
- -font font, -fn font
- Set the XEmacs window's font to that specified by
font. You will find the various X fonts in the
/usr/lib/X11/fonts directory. XEmacs works with
either fixed- or variable-width fonts, but will probably look
better with a fixed-width font.
- -scrollbar-width pixels
- Specify the width of the vertical scrollbars.
- -scrollbar-height pixels
- Specify the height of the horizontal scrollbars.
- -bw pixels, -borderwidth pixels
- Set the XEmacs window's border width to the number of
pixels specified by pixels. Defaults to one pixel on each
side of the window.
- -ib pixels, -internal-border-width
pixels
- Specify the width between a frame's border and its text, in
pixels. Defaults to one pixel on each side of the window.
- -fg color, -foreground color
- Sets the color of the text.
See the file /usr/share/X11/rgb.txt for a list of valid
color names.
- -bg color, -background color
- Sets the color of the window's background.
- -bd color, -bordercolor color
- Sets the color of the window's border.
- -mc color
- Sets the color of the mouse pointer.
- -cr color
- Sets the color of the text cursor.
- -rv, -reverse
- Reverses the foreground and background colors (reverse video).
Consider explicitly setting the foreground and background colors
instead of using this option.
- -xrm argument
- This allows you to set an arbitrary resource on the command
line. argument should be a resource specification, as might
be found in your .Xresources or .Xdefaults file.
You can also set resources, i.e. X default values, for
your XEmacs windows in your .Xresources or
.Xdefaults file (see xrdb(1)).
Use the following format:
- Emacs.keyword:value
or
- Emacs*EmacsFrame.keyword:value
where value specifies the default value of
keyword. (Some resources need the former format; some the
latter.)
You can also set resources for a particular frame by using the
format
- Emacs*framename.keyword:value
where framename is the resource name assigned to that
particular frame. (Certain packages, such as VM, give their frames
unique resource names, in this case "VM".)
XEmacs lets you set default values for the following
keywords:
- default.attributeFont (class Face.AttributeFont)
- Sets the window's text font.
- default.attributeForeground (class
Face.AttributeForeground)
- Sets the window's text color.
- default.attributeBackground (class
Face.AttributeBackground)
- Sets the window's background color.
- face.attributeFont (class

FILES
Lisp code is read at startup from the user's init
file, $HOME/.emacs.
/usr/local/info - files for the Info documentation browser (a
subsystem of XEmacs) to refer to. The complete text of the
XEmacs Reference Manual and the XEmacs Lisp Programmer's
Manual is included in a convenient tree structured form.
/usr/local/lib/xemacs-$VERSION/info - the Info files may be here
instead.
/usr/local/lib/xemacs-$VERSION/lisp/* - Lisp source files and
compiled files that define most editing commands. The files are
contained in subdirectories, categorized by function or individual
package. Some are preloaded; others are autoloaded from these
directories when used.
/usr/local/lib/xemacs-$VERSION/etc - some files of information,
pixmap files, other data files used by certain packages, etc.
/usr/local/lib/xemacs-$VERSION/$CONFIGURATION - various programs
that are used with XEmacs.
/usr/local/lib/xemacs-$VERSION/$CONFIGURATION/DOC - contains the
documentation strings for the Lisp primitives and preloaded Lisp
functions of XEmacs. They are stored here to reduce the size
of XEmacs proper.
/usr/local/lib/xemacs/site-lisp - locally-provided Lisp files.
BUGS AND HELP
There is a newsgroup, comp.emacs.xemacs, for
reporting XEmacs bugs and fixes and requesting help. But
before reporting something as a bug, please try to be sure that it
really is a bug, not a misunderstanding or a deliberate feature. We
ask you to read the section ``Reporting XEmacs Bugs'' near the end
of the reference manual (or Info system) for hints on how and when
to report bugs. Also, include the version number of the
XEmacs you are running and the system you are running it on
in every bug report that you send in. Finally, the more you
can isolate the cause of a bug and the conditions it happens under,
the more likely it is to be fixed, so please take the time to do
so.
The newsgroup is bidirectionally gatewayed to and from the
mailing list xemacs@xemacs.org. You can read the
list instead of the newsgroup if you do not have convenient Usenet
news access. To request to be added to the mailing list, send mail
to xemacs-request@xemacs.org.
(Do not send mail to the list itself.)
The XEmacs maintainers read the newsgroup regularly and
will attempt to fix bugs reported in a timely fashion. However, not
every message will get a response from one of the maintainers. Note
that there are many people other than the maintainers who read the
newsgroup, and will usually be of assistance in helping with any
problems encountered.
If you need more personal assistance than can be provided by the
newsgroup, look in the SERVICE file (see above) for a list of
people who offer it.
For more information about XEmacs mailing lists, see the file
/usr/local/lib/xemacs-$VERSION/etc/MAILINGLISTS.

AUTHORS
XEmacs was written by Steve Baur <steve@xemacs.org>, Martin Buchholz
<martin@xemacs.org>,
Richard Mlynarik <mly@adoc.xerox.com>, Hrvoje
Niksic <hniksic@xemacs.org>, Chuck
Thompson <cthomp@xemacs.org>, Ben Wing
<ben@xemacs.org>, Jamie
Zawinski <jwz@jwz.org>, and
many others. It was based on an early version of GNU Emacs
Version 19, written by Richard Stallman <rms@gnu.org> of the Free Software
Foundation, and has tracked subsequent releases of GNU Emacs
as they have become available. It was originally written by Lucid,
Inc. (now defunct) and was called Lucid Emacs.
Chuck Thompson wrote the XEmacs redisplay engine,
maintains the XEmacs FTP and WWW sites, and has put out all
releases of XEmacs since 19.11 (the first release called
XEmacs). Ben Wing wrote the Asian-language support, the
on-line documentation (including this man page and much of the
FAQ), the external widget code, and retooled or rewrote most of the
basic, low-level XEmacs subsystems. Jamie Zawinski put out
all releases of Lucid Emacs, from the first (19.0)
through the last (19.10), and was the primary code contributor for
all of these releases. Richard Mlynarik rewrote the XEmacs
Lisp-object allocation system, improved the keymap and minibuffer
code, and did the initial synching of XEmacs with GNU
Emacs Version 19.
Many others have also contributed significantly. For more
detailed information, including a long history of XEmacs
from multiple viewpoints and pretty pictures and bios of the major
XEmacs contributors, see the XEmacs About Page (the
About XEmacs option on the Help menu).
