tree_sitter_dot/
lib.rs

1//! This crate provides dot 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 = r#"
8//!     graph {
9//!         a -- b
10//!     }
11//! "#;
12//! let mut parser = tree_sitter::Parser::new();
13//! parser.set_language(tree_sitter_dot::language()).expect("Error loading dot grammar");
14//! let tree = parser.parse(code, None).unwrap();
15//! ```
16//!
