1//! This crate provides Apache Groovy language support for the [tree-sitter][] parsing library.
2//!
3//! Typically, you will use the [LANGUAGE][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//! def greet(name) {
9//!     def msg = name ?: 'World'
10//!     println "Hello, ${msg}!"
11//! }
12//! greet 'Groovy'
13//! "#;
14//! let mut parser = tree_sitter::Parser::new();
15//! let language = dekobon_tree_sitter_groovy::LANGUAGE;
16//! parser
17//!     .set_language(&language.into())
18//!     .expect("Error loading Groovy parser");
19//! let tree = parser.parse(code, None).unwrap();
20//! assert!(!tree.root_node().has_error());
21//! ```
22//!
23//! [LANGUAGE]: crate::LANGUAGE
24//! [Parser]: https://docs.rs/tree-sitter/*/tree_sitter/struct.Parser.html
