backyard-parser

Parse PHP code to AST node.

features

• Parse string to AST (parse() & parse_eval())

usage

fn main() {
  let arena = bumpalo::Bump::new();
  let code = r#"<?php
  function hello_world($foo) {
    var_dump($foo);
  }"#;

  let parsed = backyard_parser::parse(&arena, code).unwrap();
  println!("{:?}", parsed.print(false, false));
}

Notice this output is not including leadings, trailings and location because we print it with print(false, false), more on backyard-nodes.
