tree_sitter_al/
lib.rs

1//! This crate provides Al language support for the [tree-sitter][] parsing library.
2//!
3//! Typically, you will use the [LANGUAGE][] constant to add this grammar 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//! "#;
11//! let mut parser = Parser::new();
12//! let language = tree_sitter_al::LANGUAGE;
13//! parser
14//!     .set_language(&language.into())
15//!     .expect("Error loading Al grammar");
16//! let tree = parser.parse(code, None).unwrap();
17//! assert!(!tree.root_node().has_error());
18//! ```
19//!
