tree_sitter_less/
lib.rs

1//! This crate provides LESS language support for the [tree-sitter][] parsing library.
2//!
3//! Typically, you will use the [language][language func] function 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//! $blue: #056ef0;
9//! "#;
10//! let mut parser = tree_sitter::Parser::new();
11//! parser.set_language(&tree_sitter_less::language()).expect("Error loading LESS grammar");
12//! let tree = parser.parse(code, None).unwrap();
13//! assert!(!tree.root_node().has_error());
14//! ```
15//!
