Hi, all, if you are not interested in the Modelica system definition and simulation language, you can stop here ;-)
I have been looking for a TextMate bundle that supported Modelica —see, for instance, http://openmodelica.org%E2%80%94, and could not find one, but I found a SublimeText version, and instructions on how to create a TextMate one.
If you are interested, you might want to look for https://github.com/juandesant/Modelica.tmbundle
Cheers, Juande.
