How can I use this to parse code in OCaml?

[roddyyaga]

Hi, I'd like to use tree-sitter from OCaml in the same way I'd use e.g. the tree-sitter rust bindings (i.e. I don't want different OCaml types for each language). How can I do this? I see there are repos to parse different languages (e.g. https://github.com/returntocorp/ocaml-tree-sitter-typescript) but I'm not sure how to work with them (they have public_name in dune files but they don't appear to be opam packages). Or should I use this repo directly, and if so how?

Thanks, Roddy

Ideally you should use https://github.com/returntocorp/ocaml-tree-sitter-languages and each language would be an OPAM package, but this is not the case right now.

Makes sense. I couldn't get this repo working with opam (I got this error:

[ERROR] The compilation of tree-sitter.~dev failed at "make".

but after copying it and a language repo into my project and removing the public_name stanzas as mentioned above I managed to get it working.
