I have syntax highlighting files for Pyret in vim (.vim) and emacs (.el) and would like to use them in Sublime Text (3).
According to this answer and other research, Sublime Text style themes are written in TextMate format.
There exists a tool to help convert from TextMate to Emacs, but I contacted the author and he isn't aware of any tools to help facilitate the opposite conversion.
A similar question was asked (re: vim) but not answered a year ago: .vim syntax highlighting to textmate or sublime text 2 -- that asker ended up building his own TextMate theme manually, but I'm not sure how to go about that.
I would like to know if there have been developed any tools to help convert a vim or emacs syntax style file to TextMate, and, if not, how I would go about converting the vim/el files into JSON/XML for importing into TextMate.
