Most of the GNU Emacs text editor is written in the programming
|
|
language called Emacs Lisp. You can write new code in Emacs Lisp and
|
|
install it as an extension to the editor. However, Emacs Lisp is more
|
|
than a mere ``extension language''; it is a full computer programming
|
|
language in its own right. You can use it as you would any other
|
|
programming language.
|
|
|
|
Because Emacs Lisp is designed for use in an editor, it has special
|
|
features for scanning and parsing text as well as features for
|
|
handling files, buffers, displays, subprocesses, and so on. Emacs
|
|
Lisp is closely integrated with the editing facilities; thus, editing
|
|
commands are functions that can also conveniently be called from Lisp
|
|
programs, and parameters for customization are ordinary Lisp
|
|
variables.
|
|
|
|
This manual describes Emacs Lisp, presuming considerable familiarity
|
|
with the use of Emacs for editing. (See The GNU Emacs Manual for this
|
|
basic information.) Generally speaking, the earlier chapters describe
|
|
features of Emacs Lisp that have counterparts in many programming
|
|
languages, and later chapters describe features that are peculiar to
|
|
Emacs Lisp or relate specifically to editing.
