GNU Emacs

<p>GNU Emacs is a <a href="/facts/Text_editor/jPCgtbvN">text editor</a> and suite of <a href="/facts/Free_software/IaoVtJXn">free software</a> tools. Its development began in 1984 by <a href="/facts/GNU_Project/mjc8AwM6">GNU Project</a> founder <a href="/facts/Richard_Stallman/hhoPN0Mw">Richard Stallman</a>, based on the <a href="/facts/Emacs/BvGxuAxQ">Emacs</a> editor developed for <a href="/facts/Unix/0pNL2seI">Unix</a> operating systems. GNU Emacs has been a central component of the <a href="/facts/GNU/HlAKKBdt">GNU</a> project and a flagship project of the <a href="/facts/Free_software/IaoVtJXn">free software</a> movement.
</p><p>The program's tagline is "the extensible self-documenting text editor." Most functionality in GNU Emacs is implemented in user-accessible <a href="/facts/Emacs_Lisp/JHdBcPwM">Emacs Lisp</a>, allowing deep extensibility directly by users and through community-contributed packages. Its built-in features include a file browser and editor (<a href="/facts/Dired/Vq0c4S4y">Dired</a>), an advanced calculator (Calc), an email client and news reader (<a href="/facts/Gnus/uNM2pErW">Gnus</a>), a <a href="/facts/Language_Server_Protocol/V3pfPpGw">Language Server Protocol</a> integration, and the productivity system <a href="/facts/Org-mode/j9jrKW5r">Org-mode</a>. A large community of users have contributed extensions such as the <a href="/facts/Git/U5Ty9QmQ">Git</a> interface <a href="/facts/Magit/7dwBKzSk">Magit</a>, the <a href="/facts/Vim_(text_editor)/JXAYMDgt">Vim</a> emulation layer Evil, several search frameworks, the window manager EXWM, and tools for working with a wide range of programming languages.
