# tree-sitter-c
This crate provides a C grammar for the [tree-sitter][] parsing library. To
use this crate, add it to the `[dependencies]` section of your `Cargo.toml`
file. (Note that you will probably also need to depend on the
[`tree-sitter`][tree-sitter crate] crate to use the parsed result in any useful
way.)
``` toml
[dependencies]
tree-sitter = "0.17"
tree-sitter-c = "0.16"
```
Typically, you will use the [language][language func] function to add this
grammar to a tree-sitter [Parser][], and then use the parser to parse some code:
``` rust
let code = r#"
int double(int x) {
return x * 2;
}
"#;
let mut parser = Parser::new();
parser.set_language(tree_sitter_c::language()).expect("Error loading C grammar");
let parsed = parser.parse(code, None);
```
If you have any questions, please reach out to us in the [tree-sitter
discussions] page.
