| 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 attempts to be a full description of Emacs Lisp. For a |
| beginner's introduction to Emacs Lisp, see An Introduction to Emacs Lisp |
| Programming, by Bob Chassell, also published by the Free Software |
| Foundation. This manual presumes considerable familiarity with the use of |
| Emacs for editing; see The GNU Emacs Manual for this basic information. |
