Strings and variable names are not highlighted in scala-ts-mode compared to scala-mode

[Flowdalic]

First of all, thanks of working on scala-ts-mode. It has made working with brace-less Scala 3 code in Emacs very comfortable.

However, I found that, when using scala-ts-mode, Emacs does not highlight strings and variable names.

Compare scala-mode

with scala-ts-mode

Is there maybe a configuration option I am missing?

From just the screenshots, it looks like the treesit-font-lock-level variable is not set sufficiently. This variable by default is 3, which does not include variables, literals (strings included) etc.

So, in your configuration, can you please try setting treesit-font-lock-level to 4

(setq treesit-font-lock-level 4)

and then re-opening the Scala file?

Chiming in here to say that I was experiencing the same thing and that change worked for me. Thanks for the pointer! Might be nice to add that to the README.

@Flowdalic Can we mark this issue as resolved then?

Actually, I am re-opening this, until this is documented in the README. I may submit a PR for that.
