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.)

toml [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.

``` rust use tree_sitter::Parser;

fn main() { let code = r#" function double(x) { return x * 2; } "#; let mut parser = Parser::new(); parser .setlanguage(treesitter_javascript::language()) .expect("Error loading JavaScript grammar"); let parsed = parser.parse(code, None); println!("{:#?}", parsed); } ```
