TDOP

https://github.com/douglascrockford/TDOP adapted for NodeJS

Note This is work in progress and probably not very usable for a lot of people.

Usage

Note you may want to check out an older commit like cd4b646 to make sure the below description works as advertised.

Currently the code only parses D. Crockford's Simplified JavaScript Syntax:

# module exports a function that returns a parser:
new_parse = require 'tdop'
parse 		= new_parse()

console.log parse 'var a = 1 + 1;'
console.log parse """
  var f = function(){};
  var x = f(8);"""

Interestingly, just trying to compile a program like f(); or 1 + 1; results in compile-time errors since in the first case, f is not defined, and in the second, the expression has no effect whatsover (except taking some time to compute). Likewise, unreachable statements (e.g. code in a function body that comes after a return statement on the same level) produce errors.
