[Feature Request]: Please Support Diagnostic.codeDescription to provide external links

[bastiandoetsch]

Hey all,

it would be real nice to be able to navigate from a diagnostic to extended information specified in the CodeDescription field. To achieve this, vscode and Sublime Text just display the Diagnostic.Code field as a link that links to the CodeDescription. Would it be possible to implement this for the problems view and maybe the LSP marker?

This is how it looks in these tools:

Cheers

It would even be more awesome, to render external links in an internal browser view that would open within the IDE.

Would you be interested in contributing this feature?

I would be happy to contribute it. My solution would be to change the Diagnostic Hover to display diagnostic code with a link to the code description like sublime and vscsode do it. Does that match your expectations, @mickaelistria?

I don't think you'll be able to change the diagnostic/marker popup from LSP4E, this popup does come for the editor framework in Platform. But changes in Platform are welcome as well. Maybe the hover does already somehow support HTML...
Another way to render links would be to hook those as marker resolutions. It wouldn't be as cool, but it allows to get something working in LSP4E until Platform can better support it.
