Syntax Highlighting for GLSL in XCode 6
I'm wondering how I can change the default syntax highlighting for file extensions in XCode as there are some extensions I use for coding GLSL shaders which aren't recognised by XCode.
In the Syntax Highlighting menu there is an option to change the scheme, and there is a GLSL scheme I would like to use. There is also the option 'Default for File Type'. I would like to be able to set this default for my file types, but unfortunately I can't figure out how. Any advice would be appreciated!
Cheers,
Lou.
