1//! This crate provides Kotlin 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//! // write some kotlin code
9//! fun main(args : Array<String>) {
10//!   println("Hello, World!")
11//! }
12//! "#;
13//! let mut parser = tree_sitter::Parser::new();
14//! let language = tree_sitter_kotlin_ng::LANGUAGE;
15//! parser
16//!     .set_language(&language.into())
17//!     .expect("Error loading Kotlin parser");
18//! let tree = parser.parse(code, None).unwrap();
19//! assert!(!tree.root_node().has_error());
20//! ```
