Add a new language to Visual Studio 2010 with syntax highlighting and intellisense

Question

I am trying to add support for a different language in Visual Studio 2010. I was hoping to add custom syntax highlighting, and have some sort of basic intellisense work with it.

Answer 1

This isn't an answer on how to create custom syntax highlighting.

There is an open-source extension for visual studio 2010+ for Genero 4gl language support out of github:

It should do most of what you're looking for already, and it would certainly make a great starting point for you if you want to do more.
