ReParse - Coffeescript Edition

Purpose

This is a hand-written re-implementation of Ben Weaver's ReParse (https://github.com/weaver/ReParse). It is a (mostly) faithful reimplementation, although a few things were re-arranged to be more in line with Haskell's parsec library, with a side-line look at JSParsec. This version uses the Coffeescript class management toolkit, so it looks much more like a classic duck-typed OO implementation, the kind of thing you're familiar with from Ruby or Python. Take a peek at the examples and you'll see what I mean-- I think they're 20% cooler that Ben's, just 'cuz of how they look.

I made the parser re-usable with a new input; it's slightly faster than the javascript implementation.

I wrote this because I needed a parser for a coffeescript project, and while I liked Ben's code, I needed to disassemble it, figure out what it did, and re-write it in my own language and with my own brain. It's been nearly 14 years since I last had to write a parser; I usually work at a much higher level, but my current project required one, and this was the exercise I chose.

Requirements

Coffeescript to build/run.

Docco to produce documentation.

Both of these are specified in the package.json file.

John MacFarlane (for Pandoc, which led me down this rabbit hole in the first place)
