Sorry if this is Obvious Question #37... but I swear TM used to have Rails-specific syntax highlighting and that disappeared (is this possible?) in one of the recent betas or something. When I look at my Language selection, I only see Ruby.
Am I crazy? Wasn't there a Rails one? Can I just grab that from somewhere? It seemed to highlight more detailed and specific syntax than Ruby does....
Window -> Show Bundle Editor -> Change Filtering...
You can turn on/off bundles there as needed, Rails defaults to off.
It actually uses the same syntax as ruby, but adds a few rails functions that it highlights; and best of all the Rails snippets.
