tree_sitter_glsl/
lib.rs

1//! This crate provides glsl language support for the [tree-sitter][] parsing library.
2//!
3//! Typically, you will use the [LANGUAGE_GLSL][] constant to add this language to a
4//! tree-sitter [Parser][], and then use the parser to parse some code:
5//!
6//! ```
7//! use tree_sitter_glsl::LANGUAGE_GLSL;
8//!
9//! let code = "";
10//! let mut parser = tree_sitter::Parser::new();
11//! parser
12//!     .set_language(&LANGUAGE_GLSL.into())
13//!     .expect("Error loading glsl language");
14//! let tree = parser.parse(code, None).unwrap();
15//! ```
16//!
