//! This crate provides EmbeddedTemplate language support for the [tree-sitter][] parsing library. //! //! Typically, you will use the [LANGUAGE][] constant to add this language to a //! tree-sitter [Parser][], and then use the parser to parse some code: //! //! ``` //! use tree_sitter::Parser; //! //! let code = r#" //! //! //! <% if (true) { %> //!
