tree_sitter_printf/
lib.rs

1//! This crate provides printf format language support for the [tree-sitter] parsing library.
2//!
3//! Typically, you will use the [`LANGUAGE`] constant 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"%s, %s %d, %.2d:%.2d\n";
8//! let mut parser = tree_sitter::Parser::new();
9//! let language = tree_sitter_printf::LANGUAGE;
10//! parser
11//!     .set_language(&language.into())
12//!     .expect("Error loading printf format parser");
13//! let tree = parser.parse(code, None).unwrap();
14//! assert!(!tree.root_node().has_error());
15//! ```
16//!
