TVP contains no project/library symbols

[nkgm]

Describe the bug

Move the cursor to a symbol in a source file and invoke reveal_in_tree().

TVP appears with Projects and Libraries top level nodes fully collapsed. Upon expanding them, these nodes contain the full package structures for the underlying artifacts, but theres no leaf nodes, ie the package nodes are devoid of any actual symbols.

The only symbols found are under Projects > [ProjectName]-build for the sbt build itself.

Expected behavior

TVP should contain symbols for Projects and Libraries.

Hey @nkgm thanks for reporting. What version of Scala are you using? If Scala 3 then this isn't supported yet in Metals.

[nkgm]

Hi @ckipp01, yes I'm using Scala 3, I wasn't aware of this limitation. Could this be why vim.lsp.buf.definition() also doesn't work in my project?

[ckipp01]

No the definition request should for sure work. Do you have a minimal reproduction of a case where it's not working?

[nkgm]

I created a minimal project for which definition() didn't work, pushed to github, and just before posting this comment, I gave it one last try and it worked! Maybe Metals needed more time indexing even though it's a super minimal project of 2 source files and no dependencies.

My main project on the other hand had way more time to "settle", yet I couldn't get it to work. Maybe it was :MetalsCompileClean or wiping and reimporting the build (all of which I had tried several times before opening this issue) or something else I did before going afk for a few hours but, when I'm back I give it another shot and it's working!

I had similar issues before where I couldn't tell if Metals is doing something or needs a restart. Would :MetalsToggleLogs show the full picture, or is there someplace else I should check?

If Scala 3 then this isn't supported yet in Metals.

Is there an issue or some other source tracking Scala 3 support I can refer to in the future?

Yea this should help a bit. At least it will show you if something is getting screwed up or not.

Yea you can take a look at the main Metals tracker and look for things tagged with Scala 3: https://github.com/scalameta/metals/issues?q=is%3Aissue+is%3Aopen+label%3A%22Scala+3%22.
