Emacs Lisp is a dialect of the Lisp programming language used by the GNU Emacs and XEmacs text editors. It is used for implementing most of the editing functionality built into Emacs, the remainder being written in C. Emacs Lisp is also referred to as Elisp, although there is also an older, unrelated Lisp dialect with that name. Users of Emacs commonly write Emacs Lisp code to customize and extend Emacs. Other options include the "Customize" feature that's in GNU Emacs since version 20. This provides a set of preference pages and when the user saves their preferences, Customize writes the necessary Emacs Lisp code. Emacs Lisp can also function as a scripting language, much like the Unix Bourne shell or Python, by calling Emacs in "batch mode". In this way it may be called from the command line or via an executable file, and its editing functions, such as buffers and movement commands are available just as in the normal mode.
