tree-sitter-ocaml

This crate provides OCaml language support for the tree-sitter parsing library. There are separate languages for implementations (.ml), interfaces (.mli) and types.

Installation

To use this crate, add it to the [dependencies] section of your Cargo.toml file. (Note that you will probably also need to depend on the tree-sitter crate to use the parsed result in any useful way.)

[dependencies]
tree-sitter = "0.23"
tree-sitter-ocaml = "0.23"

Usage

Typically, you will use LANGUAGE_OCAML to add this language to a tree-sitter Parser, and then use the parser to parse some code:

let code = r#"
    module M = struct
      let x = 0
    end
"#;
let mut parser = tree_sitter::Parser::new();
let language = tree_sitter_ocaml::LANGUAGE_OCAML;
parser
    .set_language(&language.into())
    .expect("Error loading OCaml language");
let tree = parser.parse(code, None).unwrap();

Use LANGUAGE_OCAML_INTERFACE to parse interface files (with .mli extension) and LANGUAGE_OCAML_TYPE to parse type signatures.
