Support for Stub elements and indexes? #17

Open Tomasu opened 4 years ago

Hi,

I think it'd be useful if this library supported intellij's Stub feature. I'd like to be able to add some StubIndex's to my language plugin.

It seems to me that stub indexes are very specific to the language you are building:

The stub tree contains only a subset of the nodes. Typically it contains only the nodes that are needed to resolve the declarations contained in this file from external files.

I don't see how a generic library could decide what should be put in the index and what's not needed, but perhaps I'm missing something. Did you have something specific in mid?
