C parser or possible to translate from tree sitter?

[ShiinaManatsu]

hey guys, I want write a hlsl parser, it is good to base on a c langium parser which I have not found yet, I implement a tree sitter version based on tree-sitter-c, that works pretty well.

I found there is some similarity between langium and tree sitter, looks like can be 1:1 translated maybe?

Yes I assume it would be possible to generate Langium grammar files from Tree-sitter JS grammars, but I'm not aware of any such generator.

Note that the parser engines behave fundamentally differently: Tree-sitter does LR parsing, Chevrotain does LL parsing. So even if you automatically transform a grammar to Langium, it's rather likely that it won't work.
