/***********************************************************************
A JavaScript tokenizer / parser / beautifier / compressor.
This version is suitable for Node.js. With minimal changes (the
exports stuff) it should work on any JS platform.
This file contains the tokenizer/parser. It is a port to JavaScript
of parse-js [1], a JavaScript parser library written in Common Lisp
by Marijn Haverbeke. Thank you Marijn!
[1] http://marijn.haverbeke.nl/parse-js/
Exported functions:
- tokenizer(code) -- returns a function. Call the returned
function to fetch the next token.
- parse(code) -- returns an AST of the given JavaScript code.
