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.
The language I am trying to add is 4Js Genero (a newer version of Informix-4GL). I basically just need support for the .4gl and .per file extensions that are used in Genero/4GL. Does anyone know how to do this, or can point me in the right direction?
It's not really for the faint of heart. Don't underestimate how much work you'll have to put in.
You'll need the Visual Studio 2010 SDK, and then to read (and re-read, and re-read(*)) all about Language Services
The purpose of a language service in Visual Studio is to provide language-specific support for editing source code in the integrated development environment (IDE). You implement a language service as part of a VSPackage.
(*) - unless it all immediately makes sense to you.
