//! This crate provides objc language support for the [tree-sitter][] parsing library. //! //! Typically, you will use the [language][language func] function to add this language to a //! tree-sitter [Parser][], and then use the parser to parse some code: //! //! ``` //! let code = ""; //! let mut parser = tree_sitter::Parser::new(); //! parser.set_language(tree_sitter_objc::language()).expect("Error loading objc grammar"); //! let tree = parser.parse(code, None).unwrap(); //! ``` //! //!
