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 }.

slang ,
EMACS )
EMACS : /

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 ).
