GNU Emacs is a text editor and suite of free software tools. Its development began in 1984 by GNU Project founder Richard Stallman,[5] based on the Emacs editor developed for Unix operating systems. GNU Emacs has been a central component of the GNU project and a flagship project of the free software movement.[6][7]

The program's tagline is "the extensible self-documenting text editor."[8] Most functionality in GNU Emacs is implemented in user-accessible Emacs Lisp,[9] allowing deep extensibility directly by users and through community-contributed packages. Its built-in features include a file browser and editor (Dired), an advanced calculator (Calc), an email client and news reader (Gnus), a Language Server Protocol integration,[10] and the productivity system Org-mode. A large community of users have contributed extensions such as the Git interface Magit, the Vim emulation layer Evil, several search frameworks, the window manager EXWM,[11] and tools for working with a wide range of programming languages.
