tree-sitter-gn

This crate provides a GN grammar for the tree-sitter parsing library. 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 = "0.20.10"
tree-sitter-gn = "1.0.0"

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

let code = r#"
import("//build/config/BUILDCONFIG.gn")

if (is_debug) {
  executable("foo") {
    sources = [
      "foo.cc",
    ]
  }
}
"#;
let mut parser = Parser::new();
parser.set_language(tree_sitter_gn::language()).expect("Error loading GN grammar");
let parsed = parser.parse(code, None);
