Missing syntax highlighting in Polyglot Notebook extension

[akselkvitberg]

Syntax highlighting in polyglot notebooks are broken after the November update.

This is how a snippet looks in the default theme

This is how a snippet looks with Rosé Pine

Jupyter notebooks using python seems to be working fine. This is just affecting polyglot notebooks with C#, F# and Powershell.

Honestly I'm not sure how to reproduce this as I have no experience with using notebooks but if notebooks are a shareable file and you can provide an example file of this happening I'll take a look :)

See here for an example covering some of the usual syntaxes

I found the solution. The theme does not enable semantic highlighting by default, so it needs to be enabled manually in the settings.
"editor.semanticHighlighting.enabled": true

I regard this as solved, but perhaps semantic highlighting should be enabled by the theme?

Good find! I wouldn’t mind enabling it in the theme but some values may need tweaked. Happy to look at this soon but if anyone notices weird or poor highlighting with semantic enabled please post screenshots here :)
