Tree sitter has a C runtime, and often a C scanner.

If the tree-sitter runtime requirements are prohibitive and a pure JVM solution (IOW, no JNI) mandatory, then I'd recommend using antlr[0] with its representative grammar[1] as a starting point. See here[2] for more details.

0 - https://www.antlr.org/

1 - https://github.com/antlr/grammars-v4/blob/master/javascript/...

2 - https://github.com/antlr/grammars-v4/wiki

I agree that the Antlr Typescript grammar is underwhelming, and I also agree with the difficulty of not having a well defined owner of the project to interact with. My main use case is parsing TS type definitions, and the grammar from the grammars-v4 repo doesn't parse anything starting with 'declare', which is pretty fundamental.

I'm the maintainer of swc4j. I had been using Antlr for many years, but was deeply disappointed by Antlr. So I created swc4j.

Why Antlr is not the one? Hope the following blog I wrote may explain.

Right, that would be another native bridge solution.

See my peer comment for another option. :-)
