Disable content-assist in comments

It seems like RLS completes inside comments as it's not really desired by typical usage.

This seems reasonable. However, I wonder if there is a case for completion in comments?

In any case it is feasible to implement this. Completion is handled by a request, the implementation of which can be found in src/actions/requests.rs

// requests.rs:294
impl RequestAction for Completion {
...

Write a little logic to tell if the position is commented => simply return empty completion suggestions here.

Also a good one to cover with a test case.

This seems like something which would be better handled by Racer - @kngwyu do you think that is possible?

@nrc
I think we can.
In current implementation, racer masks all comments before trying to complete. So when the cursor is in comments, racer tries to find completion candidates to empty context...

Same here. While suggestions in comments are useful in general (e.g. completion of type names for documentation), it is really unhelpful when it triggers after typing a dot.

Also it triggers in the middle of nowhere (e.g. in the empty file or after ;, which is nonsense) .

Any news on that? It really slows down typing comments (and thus documentation) because of popping suggestions.

Perhaps, some instructions to point where to fix?
