To quote the Emacs Manual: Emacs is the extensible, customizable, self-documenting real-time display editor. If this seems to be a bit of a mouthful, an easier explanation is Emacs is a text editor and more. At its core is an interpreter for Emacs Lisp (``elisp'', for short), a dialect of the Lisp programming language with extensions to support text editing. Some of the features of GNU Emacs include: Content sensitive major modes for a wide variety of file types, from plain text to source code to HTML files. Complete online documentation, including a tutorial for new users. Highly extensible through the Emacs Lisp language. Support for many languages and their scripts, including all the European ``Latin'' scripts, Russian, Greek, Japanese, Chinese, Korean, Thai, Vietnamese, Lao, Ethiopian, and some Indian scripts. (Sorry, Mayan hieroglyphs are not supported.) A large number of extensions which add other functionality. The GNU Emacs distribution includes many extensions; many others are available separately--even a web browser Features Coming Soon The latest release supports variable width and variable height fonts, playing sounds, and the inclusion of images in a document, as well as tool bars, plus nicer menus and scroll bars. Some Unicode support is available, and we are working on improving and expanding it. Supported Platforms Emacs 20 runs on these operating systems regardless of the machine type: FreeBSD GNU/Linux NetBSD OpenBSD Solaris SunOS Ultrix Here are other machines that GNU Emacs supports, as of version 21.1. The definitive reference for this is the etc/MACHINES file distributed with GNU Emacs, which also lists special requirements for these systems if compiling GNU Emacs from source.

We have listed an operating system here if it can run on more than one machine type, or if other operating systems can also run on the same machine type. Many of the computer types listed above always or usually run one particular operating system developed by the computer manufacturer. (Often this is a variant of Unix.) We have not listed the names of those operating systems here. Berkeley Unix (BSD) 4.1, 4.2, 4.3, 4.4 Esix Microport MS-DOS (aka MSDOG) SCO Unix System V rel 0, rel 2, rel 2.2, rel 3, rel 4.0.3, rel 4.0.4 Uniplus 5.2 MS-Windows NT, Windows 9X, Windows 2000, and Windows XP Xenix Why is it called Emacs? The name ``Emacs'' was originally chosen as an abbreviation of Editor MACroS. The original Emacs implemention was written for the Incompatible Timesharing System (ITS) as a collection of TECO macros for ITS TECO. There was a custom of giving such macro packages names ending in ``mac'' or ``macs''. A further reason for choosing this particular name was that the abbreviation ``e'' was unused at the time on ITS. The Emacs FAQ contains a longer explanation, as well as a brief history of Emacs. Obtaining GNU Emacs GNU Emacs can be obtained from <http://ftp.gnu.org/pub/gnu/emacs/>, or from a local FTP mirror; see the list of mirrors here. The GNU Emacs CVS repository is available for general access through savannah.gnu.org. Getting Help with GNU Emacs Information on getting help with GNU software in general is available at the Get Help with GNU Software page. Manuals The Free Software Foundation publishes three manuals about GNU Emacs. They are the Emacs Manual, the Introduction to Emacs Lisp Programming, and the Emacs Lisp Reference Manual. You can order any of these manuals in printed form from the Free Software Foundation. Also an online manual is available at http://www.gnu.org/manual/emacs/index.html The source code for the Emacs Manual is included in the Emacs distribution itself. The Emacs Lisp Reference Manual is available as a separate distribution on ftp.gnu.org. The Emacs Reference Card (texinfo source) is also translated into Czech. FAQ The Emacs FAQ. The Emacs FAQ for the Microsoft Windows port. Mailing Lists The mailing list <help-gnu-emacs@gnu.org> is specifically for asking for help with GNU Emacs. This is equivalent to the newsgroup <gnu.emacs.help>. To subscribe, visit the <help-gnu-emacs web page>. The Savannah page for Emacs mailing lists lists some more lists related to Emacs. There are other GNU mailing lists and newsgroups, including several on GNU Emacs and its extensions. Usenet There is a newsgroup specifically for asking for help with GNU Emacs gnu.emacs.help. This newsgroup is gatewayed automatically to the mailing list <help-gnu-emacs@gnu.org>, so anything you post on one of them appears on the other as well. Finding packages for GNU Emacs If you are looking for ELisp packages, check out the following resources: the Emacs Wiki (see below) the Emacs FAQ, under the sections Finding/Getting Emacs and Related packages and Major Emacs Lisp Packages, Emacs Extensions, and Related Programs Further Information The Savannah Emacs page has additional information about Emacs, including CVS access to the Emacs development sources. The Emacs Wiki is a community website which collects ELisp code, questions and answers related to ELisp code and style; introductions to ELisp packages and links to their sources; complete manuals or documentation fragments; comments on features, differences, and history of different Emacs versions, flavors, and ports; jokes; pointers to clones and Emacs look-alikes, as well as references to other Emacs related information on the Web. If you haven't had any experience with Lisp, you can find some useful information at The Association of Lisp Users. We also have a copy of the paper by Richard Stallman describing the design of the original Emacs and the lessons to be learned from it. How to Help with GNU Emacs To contact the maintainers of Emacs, either to report a bug or to contribute fixes or improvements, send mail to <bug-gnu-emacs@gnu.org>. Return to GNU's home page.
