Is there a flex - bison parser for javascript?

Question

Is there a parser available in the open ? Else, i'm planning to write one using the grammar rules in http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-262.pdf

Thanks.

I think you can try Jison.

Jison takes a context-free grammar as input and outputs a JavaScript file capable of parsing the language described by that grammar. You can then use the generated script to parse inputs and accept, reject, or perform actions based on the input. If you’re familiar with Bison or Yacc, or other clones, you’re almost ready to roll.
