GNU Emacs
GNU Emacs is an open-source editor that was first developed by Richard Stallman, the founder of the GNU Project and its development began in 1985. It is written in C and its own programming language, Emacs Lisp. It is using Emacs Lisp that it can be extended, by use of extensions and modifying the configuration script ~/.emacs. Thanks to Emacs Lisp it is perhaps the single most extensible text editor available. It is so powerful, in fact, that it can be used to browse the web, read RSS feeds, play games, view emails, etc. It is fairly slow to startup, however, and uses a similar amount of RAM to Atom. It is provided by the app-editors/emacs package. It has both a version available from the command-line and a GUI. app-emacs contains some extensions for extended GNU Emacs. To list packages in that category run:user $ emerge --search "%@^app-emacs" it is easier to use for beginners than Vim, but it still has a steep learning curve. Several text editors exist that are similar to GNU Emacs and they usually have "emacs" in their name. For example, XEmacs is a fairly old fork of GNU Emacs, and is provided by the app-editors/xemacs package.
