//! This crate provides YAML language support for the [tree-sitter][] parsing library.
|
|
//!
|
|
//! Typically, you will use the [language][language func] function to add this language to a
|
|
//! tree-sitter [Parser][], and then use the parser to parse some code:
|
|
//!
|
|
//! ```
|
|
//! let code = r#"
|
|
//! key: value
|
|
//! list:
|
|
//! - item1
|
|
//! - item2
|
|
//! "#;
|
|
//! let mut parser = tree_sitter::Parser::new();
|
|
//! parser.set_language(&tree_sitter_yaml::LANGUAGE.into()).expect("Error loading YAML grammar");
|
|
//! let tree = parser.parse(code, None).unwrap();
|
|
//! assert!(!tree.root_node().has_error());
|
|
//! ```
|
|
//!
