Switch between files

[olafurpg]

Currently, metadoc only works for a single source file. It should be possible to switch between files when jumping to symbols defined in other compilation units.

For inspiration of how this could be implemented using the internal EditorService service see the example given here: microsoft/monaco-editor#291 (comment)

After some digging in the vscode codebase here are some more inspiration if we go the route of providing our own override services.

• In standalone mode it looks like the service implementations are used can be found in src/vs/editor/standalone/browser/simpleServices.ts, especially the IEditorService and ITextModelService implementations seem of interest.
• Interface for IEditorService
• Interface for ITextModelService

Thanks for the links @jonas. I will try to take a stab at this.

I'm struggling with this one, my progress so far is here https://github.com/scalameta/metadoc/compare/filenames?expand=1

It seems ITextModelService is what we really want, but I can't figure out how we call registerTextModelContentProvider with a custom ITextModelContentProvider. Once we nail that, I suspect implementing the provideTextContent will be quite simple.

Any ideas?

I think you are close. ITextModelService was recently renamed from ITextModelResolverService so using the name textModelResolverService might be the missing piece.

BTW I suggest you create a PR as it makes it easier to comment.

Also I don't think we necessarily need to care about registerTextModelContentProvider if we control the resolver service ourselves.

textModelResolverService is what I was missing! I got something working now in #33 😄

Fixed in #33
