I am currently experimenting with elixir using gedit under Debian linux, which uses gtksourceview. The elixir homepage contains editor code support for emacs, textmate and vi, but unfortunately not for gtksourceview.
Because programming is no fun without proper syntax highlighting, I spend the last days writing an elixir.lang spec file for gtksourceview. I would like to share it. Just copy it to /usr/share/gtksourceview-3.0/language-specs/ and any application using gtksourceview should start to show elixir syntax.
It is still my first attempt writing a language spec file for gtksourceview, so please handle it as very alpha. Any feedback is very much appreciated.
