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. 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.
