1//! This crate provides perl language support for the [tree-sitter][] parsing library.
2//!
3//! Typically, you will use the [language][language func] function to add this language to a
4//! tree-sitter [Parser][], and then use the parser to parse some code:
5//!
6//! ```
7//! let code = "";
8//! let mut parser = tree_sitter::Parser::new();
9//! let language = ts_parser_perl::LANGUAGE;
10//! parser.set_language(&language.into()).expect("Error loading perl grammar");
11//! let tree = parser.parse(code, None).unwrap();
12//! ```
13//!
