I’m trying to add support for a language in Visual Studio Code using TypeScript, and I’ve run into a bit of a problem.

I’ve managed to add a Hover that shows where something is defined. But now I want to add function definitions when hovering over and got stuck on how to do this or maybe how it’s usually done? I’ve seen someone make a .json file and take it from there, but is this the right approach?

I’ve tried searching through some other projects that also add support for a custom language but they mostly seem to be leaving this feature out…

I’d really appreciate any help. Thanks a lot in advance.
