I'm very pleased you got it working!

It works great! I don't even need to restart sublime text!

Dropped in to say thanks! Works beautifully for me!

Where does it go?

This is exactly what we were planning on adding to the RSpec package in the Sublime Text org on GitHub. Mind if I borrow this and plop it right into that package? Seems to make sense to consolidate our efforts!

Added a check for erb files here: https://gist.github.com/2142985

Error loading syntax file "Packages/RSpec/RSpec.tmLanguage": Error parsing plist xml: Failed to open file In file "Packages/RSpec/RSpec.tmLanguage" Error on Ubuntu any ideas how to fix it. Dropped the syntax_highlighting.py file into "/home/$usename$/.config/sublime-text-2/Packages/User" but still getting the error.

For everyone still coming across this gist and needing more control over applying the correct syntax to files in ST2, I encourage you to consider DetectSyntax [1], a plugin I created based on JeanMertz's work above.

@survivorist use "Package Control" and install "RSpec"

I've been seeing the same error on Sublime Text 2 for Windows. Tried adding the @irakli-janiashvili version noted above to my package directory, but still receiving same error.

Thanks!
