tree_sitter_jsdoc/lib.rs
1//! This crate provides JSDoc 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//! * This is a JSDoc comment
10//! *
11//! * @param {string} foo
12//! */
13//! "#;
14//! let mut parser = tree_sitter::Parser::new();
15//! let language = tree_sitter_jsdoc::LANGUAGE;
16//! parser
17//! .set_language(&language.into())
18//! .expect("Error loading JSDoc parser");
19//! let tree = parser.parse(code, None).unwrap();
20//! assert!(!tree.root_node().has_error());
21//! ```
22//!
