lib.rs

1//! This crate provides HTML 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//! "#;
9//! let mut parser = tree_sitter::Parser::new();
10//! let language = tree_sitter_html::LANGUAGE;
11//! parser
12//!     .set_language(&language.into())
13//!     .expect("Error loading HTML parser");
14//! let tree = parser.parse(code, None).unwrap();
15//! assert!(!tree.root_node().has_error());
16//! ```
17//!
