Joe's Own Editor or Joe is a text editor for Unix. It serves as a stand alone editor and has clones of Vim, Emacs, Pico and WordStar. It has syntax highlighting for many common languages like Perl and C, and some for more uncommon languages like Haskell and Ada.
Installing and Configuring
Joe can be found in the AUR here or can be built from source. Extra syntax highlighting files can be found here. Some are updated files and some are brand new ones like the Erlang syntax highlighting file.
Configuring is very straight forward, it's done through rc files, located in either /etc/joe/ or /usr/local/etc/joe depending on how you installed it. They can be edited there or copied to a home folder, for example /home/user/.joerc.
