So I’m now about to look at getting visual studio integration working for our port of the Less ruby library: http://www.dotlesscss.com. This is basically a CSS preprocessor that extends on the CSS language to give you variables, mixins, nested rules etc…

What we want is to have our .Less file type take advantage of VS’s intelligence and syntax highlighting. Now as the Less language is pretty much CSS with a few extra niceties, it would seem sensible to extend on the existing VS support for CSS files.

We have started to look at VS SDK and managed to get as far as colouring all text blue (its a start). But before we start looking at the Lexer impl I really want to know if we can somehow extend whats already been done with CSS support.

Any pointers in the right direction would be appreciated.

Chris.

    Regardless of whether you choose 2005, 2008, or 2010, you’ll face the same choice – you can pick one or the other but in no way can pick both.

    1. Set .less files to open in Visual Studio’s CSS editor – as is.
    2. Write a new language service for Visual Studio from the ground up, with a syntax highlighter and IntelliSense, for your language.

    If you choose #2, then you’ll be writing what’s called a language service for Visual Studio, and there are lots of resources here and on the web (my blog has some). Be warned it’s a non-trivial task once you get past simple syntax highlighting.
