emacs GNU Emacs is an extensible, customizable text editor - and more. At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. The features of GNU Emacs include: * Content-sensitive editing modes, including syntax coloring, for a wide variety of file types including plain text, source code, and HTML. * Complete built-in documentation, including a tutorial for new users. * Support for many languages and their scripts, including all the European "Latin" scripts, Russian, Greek, Japanese, Chinese, Korean, Thai, Vietnamese, Lao, Ethiopian, and some Indian scripts. * Highly customizable, using Emacs Lisp code or a graphical customization interface. * A large number of extensions that add other functionality, including a project planner, mail and news reader, debugger interface, calendar, and more. Many of these extensions are distributed with GNU Emacs; others are available separately.
