I think @jrieken worked on the hovers

We use the tokenisers for that

@jrieken For the given example, the hover has content:
Workbench.registerEmitters(): void

That's not a valid TypeScipt syntax, that's why 'void' and 'registerEmitters' aren't colorized.
I don't think the tokenizer can be blamed for that. Looks like a the hover needs to use a different snippet such as function registerEmitters(): void or class Workbench { registerEmitters(): void }
Also note that the TypeScript grammar is somewhat context sensitive, so you can just feed it some tokens and hope for a consistenly colored content.

I would totally blame the TypeScript grammar for this because it makes no sense to be context sensitive when tokenising. The 'fix' would be for TypeScript to not use this feature but have their source unhighlighted.

@dbaeumer In the hover provider basically don't mark something as code but just return plain text

Actually I like having color in the hover. In Feb I will try to make a request to TS to better support this.

Thanks 👍

Was too busy this milestone. Moving to march.

Guess what :-)
