GNU Emacs Lisp Reference Manual is available in several formats. 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.
Book Description
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.
Table of Contents
- Introduction – Introduction and conventions used.
- Lisp Data Types – Data types of objects in Emacs Lisp.
- Numbers – Numbers and arithmetic functions.
- Strings and Characters – Strings, and functions that work on them.

- Functions – A function is a Lisp program that can be invoked from other functions.
- Macros – Macros are a way to extend the Lisp language.
- Customization – Writing customization declarations.
- Loading – Reading files of Lisp code into Lisp.
