tree_sitter_regex/
lib.rs

1//! This crate provides Regex 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//! use tree_sitter::Parser;
8//!
9//! let code = r#"
10//! [a-z]+
11//! "#;
12//! let mut parser = Parser::new();
13//! let language = tree_sitter_regex::LANGUAGE;
14//! parser
15//!     .set_language(&language.into())
16//!     .expect("Error loading Regex parser");
17//! let tree = parser.parse(code, None).unwrap();
18//! assert!(!tree.root_node().has_error());
19//! ```
20//!
