//! This crate provides ql 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_ql::language()).expect("Error loading ql grammar"); | |
//! let tree = parser.parse(code, None).unwrap(); | |
//! ``` | |
//! | |
