`@main` not colored consistently

[NoahELE]

Just like the screenshot above, I'm not sure why the same annotation is colored differently.

The first has semantic token class, while the second has semantic token other

Thanks for reporting! Looks like this is an issue with semantic highlight from Metals 🤔 does it happen consistently? I can take a look next week.

Yes, this happens consistently, usually a call to List constructor will make the @main annotation turn gray. I'm not sure what triggered this exactly.

Could you post the whole sample? I don't think I can reproduce it currently.

@main def main1(): Unit =
  println("Hello, world!")

@main def main2(): Unit =
  val list = List(1, 2, 3)
  print(list)

with "editor.semanticHighlighting.enabled": true in vscode settings.

Some vscode color theme does not enable semantic highlighting by default. You can either turn it on manually in setting or use a default theme like Default Dark Modern which enable it by default. I guess that might be the cause.

Thanks, looks like this happens if a val is in the second main, which is super curious. Do you might opening the issue under scalameta/metals ? That's where the semantic highlight is implemented

Issue opened here scalameta/metals#6823
