tree_sitter_palm/
lib.rs

1//! This crate provides palm 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//! parser.set_language(tree_sitter_palm::language()).expect("Error loading palm grammar");
10//! let tree = parser.parse(code, None).unwrap();
11//! ```
12//!
