plum

//! This crate provides plum 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_plum::LANGUAGE;

//! parser

//!     .set_language(&language.into())

//!     .expect("Error loading plum parser");

//! let tree = parser.parse(code, None).unwrap();

//! assert!(!tree.root_node().has_error());

//! ```

//!

//! [Parser]: https://docs.rs/tree-sitter/*/tree_sitter/struct.Parser.html

//! [tree-sitter]: https://tree-sitter.github.io/
