I haven't found this anywhere. Anyone figure out how to get SublimeText2 working nicely with a ruby debugger? (Like SublimeGDB but for Ruby)?
SublimeLinter does syntax check for ruby..
There are a few plugins whose names start with "Ruby" you can check them out (I don't know Ruby),but note that Sublime Text is a WONDERFUL] text editor, not an IDE.
However, there is a blurry line between text editor and IDE. There are plugins for running rspec tests, etc. I could imagine a third party writing a plugin to do this as well just as they have for C. SublimeText definitely is awesome as a text editor, but it is also extensible.
