Answer 1

Currently, language services are not extensible. You would need to replace the existing language service with your own. Authoring a language service isn't trivial. The most comprehensive example would be the IronPythonIntegration sample that ships with the Visual Studio SDK.

A simpler implementation is the RegEx Language service sample. It's pretty lightweight, but is a good starting point. There's also a pretty good writeup on the sample at http://code.msdn.microsoft.com/RegExLangSvcDD.

Hi,Ed

Thank you for your reply.
If language services are not extensible,
How about create Visual Studio Integration Package and Is it possible to implement collapsible region,set text color etc. ?

Btw:I have noticed this post,

Hi,

Can you give an example of using your language service with already registered extension?
I suppose, that users of JavaScript Language Service might use it by explicitly specifying it's GUID.
You can also provide [ProvideEditorExtension(typeof(...), ".js", 100)] attribute and create your own editor factory for javaScript files.

You need to create a language service. A language service is implemented in a VS SDK Package.
