tree-sitter-javascript
This crate provides a JavaScript 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
crate to use the parsed result in any useful
way.)
[dependencies]
tree-sitter = "0.20"
tree-sitter-javascript = "0.20"
Typically, you will use the language function to add this grammar to a tree-sitter Parser, and then use the parser to parse some code.
The below example demonstrates a simple program that parses a JavaScript function and prints the result to your terminal.
use tree_sitter::Parser;
fn main() {
let code = r#"
function double(x) {
return x * 2;
}
"#;
let mut parser = Parser::new();
parser
.set_language(tree_sitter_javascript::language())
.expect("Error loading JavaScript grammar");
let parsed = parser.parse(code, None);
println!("{:#?}", parsed);
}
If you have any questions, please reach out to us in the tree-sitter discussions page.
