tree_sitter_lua/
lib.rs

1//! This crate provides Lua language support for the [tree-sitter] parsing library.
2//!
3//! Typically, you will use the [`LANGUAGE`] constant to add this language to a
4//! tree-sitter [`Parser`], and then use the parser to parse some code:
5//!
6//! ```
7//! let code = r#"
8//! return 42
9//! "#;
10//! let mut parser = tree_sitter::Parser::new();
11//! let language = tree_sitter_lua::LANGUAGE;
12//! parser
13//!     .set_language(&language.into())
14//!     .expect("Error loading Lua parser");
15//! let tree = parser.parse(code, None).unwrap();
16//! assert!(!tree.root_node().has_error());
17//! ```
18//!
