<text, tool> /ee'maks/ (Editing MACroS, or Extensible MACro System, GNU
Emacs) A popular screen editor for Unix and most other operating systems.
Emacs is distributed by the Free Software Foundation and was Richard Stallman's
first step in the GNU project. Emacs is extensible - it is easy to add new
functions; customisable - you can rebind keys, and modify the behaviour of
existing functions; self-documenting - there is extensive on-line,
context-sensitive help; and has a real-time "what you see is what you get"
display. Emacs is writen in C and the higher levels are programmed in Emacs
Emacs has an entire Lisp system inside it. It was originally written in TECO
under ITS at the MIT AI lab. AI Memo 554 described it as "an advanced,
self-documenting, customisable, extensible real-time display editor".
It includes facilities to view directories, run compilation subprocesses and
send and receive electronic mail and Usenet news (GNUS). W3 is a web browser,
the ange-ftp package provides transparent access to files on remote FTP servers.
Calc is a calculator and symbolic mathematics package. There are "modes"
provided to assist in editing most well-known programming languages. Most of
these extra functions are configured to load automatically on first use,
reducing start-up time and memory consumption. Many hackers (including Denis
Howe) spend more than 80% of their tube time inside Emacs.
GNU Emacs is available for Unix, VMS, GNU/Linux, FreeBSD, NetBSD, OpenBSD, MS
Windows, MS-DOS, and other systems. Emacs has been re-implemented more than 30
times. Other variants include GOSMACS, CCA Emacs, UniPress Emacs, Montgomery
Emacs, and XEmacs. Jove, epsilon, and MicroEmacs are limited look-alikes.
Some Emacs versions running under window managers iconify as an overflowing
kitchen sink, perhaps to suggest the one feature the editor does not (yet)
include. Indeed, some hackers find Emacs too heavyweight and baroque for their
taste, and expand the name as "Escape Meta Alt Control Shift" to spoof its heavy
reliance on keystrokes decorated with bucky bits. Other spoof expansions include
"Eight Megabytes And Constantly Swapping", "Eventually "malloc()'s All Computer
Storage", and "Emacs Makes A Computer Slow" (see recursive acronym). See also
Latest version: 20.6, as of 2000-05-11. 21.1 (RSN) adds a new redisplay engine
with support for proportional text, images, toolbars, tool tips, toolkit scroll
bars, and a mouse-sensitive mode line.
