Switch to treesitter or linguist for syntax highlighting?

[SethTisue]

We've been using Rouge to syntax-highlight our Scala snippets for many many years now, dating back to (iirc) even before the existence of Scala 3

But Rouge seems to lack full support for Scala 3 at present, as per rouge-ruby/rouge#1885

an alternative highlighter, Pygments, does have some Scala 3 support, as per pygments/pygments#1694 , but probably it's fallen a bit out of date

and there are also other highlighters out there, for example:

• https://github.com/scala/vscode-scala-syntax via Linguist (which is what GitHub uses to highlight Scala)
• https://github.com/tree-sitter/tree-sitter-scala

It would be nice not to have to maintain so many different highlighters. Perhaps we could switch to Linguist or Treesitter for our websites.

I have a https://github.com/keynmol/scala-treesitter-highlighting which includes both a self-contained binary (that can produce HTML snippets one can inline, or can process entire markdown files) and a JVM integration that can be used for custom work as long as tree sitter libraries are loaded.

It's a personal project but I'm sure it can be polished up for scala lang website use.

That would be so cool.
