Emacs /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 Lisp}.
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 {vi}.
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.

Eight Megabytes And Constantly Swapping ( slang, EMACS) EMACS: / ee´ maks/, n. [ from Editing MACroS] The ne plus ultra of hacker editors, a programmable text editor with an entire LISP system inside it. It was originally written by Richard Stallman in TECO under ITS at the MIT AI lab; AI Memo 554 described it as “ an advanced, self- documenting, customizable, extensible real- time display editor”. It has since been reimplemented any number of times, by various hackers, and versions exist that run under most major operating systems. Perhaps the most widely used version, also written by Stallman and now called “ GNU EMACS” or GNUMACS, runs principally under Unix. ( Its close relative XEmacs is the second most popular version.) It includes facilities to run compilation subprocesses and send and receive mail or news; many hackers spend up to 80% of their tube time inside it. Other variants include GOSMACS, CCA EMACS, UniPress EMACS, Montgomery EMACS, jove, epsilon, and MicroEMACS. ( Though we use the original all- caps spelling here, it is nowadays very commonly ‘ Emacs’.) 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’ ( from when that was a lot of core), ‘ Eventually malloc() s All Computer Storage’, and ‘ EMACS Makes A Computer Slow’ ( see recursive acronym).
