JED is a text editor that is heavily extensible by the S-Lang programming language and library. It is available for all major operating systems, among others. JED's extensible nature allows for many plug-ins or extensions, which are called 'modes' in JED and emacs, ranging from programming language-specific keybindings to primitive web browsers. JED's git repository receives irregular updates ranging from months to weeks in between.
