NAME

xemacs - Emacs: The Next Generation
 

SYNOPSIS

DESCRIPTION

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

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/lib/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 Face.AttributeFont)

Sets the font for face, which should be the name of a face. Common face names are

FACE                   PURPOSE

borderWidth (class BorderWidth)

Sets the window's border width in pixels.

internalBorderWidth (class InternalBorderWidth)

Sets the window's internal border width in pixels.

borderColor (class BorderColor)

Sets the color of the window's border.

Sets the default visual XEmacs will try to use (as described above).

privateColormap (class PrivateColormap)

If set, XEmacs will default to using a private colormap.

geometry (class Geometry)

Sets the geometry of the XEmacs window (as described above).

iconic (class Iconic)

If set to on, the XEmacs window will initially appear as an icon.

scrollBarWidth (class ScrollBarWidth)

Sets the width of the vertical scrollbars, in pixels. A width of 0 means no vertical scrollbars.

scrollBarHeight (class ScrollBarHeight)

Sets the height of the horizontal scrollbars, in pixels. A height of 0 means no horizontal scrollbars.

scrollBarPlacement (class ScrollBarPlacement)

Sets the position of vertical and horizontal scrollbars. Should be one of the strings "top-left", "bottom-left", "top-right", or "bottom-right". The default is "bottom-right" for the Motif and Lucid scrollbars and "bottom-left" for the Athena scrollbars.

topToolBarHeight (class TopToolBarHeight)

Sets the height of the top toolbar, in pixels. 0 means no top toolbar.

bottomToolBarHeight (class BottomToolBarHeight)

bellVolume (class BellVolume)

Volume of the audible beep. Range is 0 through 100.

useBackingStore (class UseBackingStore)

Whether XEmacs should set the backing-store attribute of the X windows it creates. This increases the memory usage of the X server but decreases the amount of X traffic necessary to update the screen, and is useful when the connection to the X server goes over a low-bandwidth line such as a modem connection.

textPointer (class Cursor)

The cursor to use when the mouse is over text.

selectionPointer (class Cursor)

FILES

/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

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.

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).
