is it possible to map the suffix of files opened by sublime text 2 to be similar to other languages to get the text coloring? for example, when i open a *.cu file, this isn’t recognize by sublime text as a valid file extension, so it opens the file and there are no text coloring in there at all. however if you open a php or c++ files, the the file will be recognized as valid file extension, and there will be text coloring, making it much easier to read.
I know text wrangler has this feature, and you cam map *.cu file extension to be like c++ so when you open a .cu file, the text coloring will be similar to a c++ file.
Yes it is.
