This crate provides Racket language support for the tree-sitter parsing library.

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

let code = r#"
"#;
let mut parser = tree_sitter::Parser::new();
let language = tree_sitter_racket::LANGUAGE;
parser
    .set_language(&language.into())
    .expect("Error loading Racket parser");
let tree = parser.parse(code, None).unwrap();
assert!(!tree.root_node().has_error());

tree-sitter-racket

Racket parser for tree-sitter.

This grammar only implements the Racket language with the default readtable.

Status

It should be complete and compatible with Racket 8.9.

There are no plans to add support for new language currently.
