Node.js ZPAQ lib (or if none any other JavaScript ZPAQ implementation)

Question

I'm looking for a JavaScript implementation or wrapper for the ZPAQ archive format.

Requirements:

• Strong Preference: Node.js addon.
• Preferably: a Grunt addon but I'm really not expecting someone to have one of those hanging around. (For those that don't know this means that it is a Node.js addon since Grunt Addons is a subset of Node.js addons)
• Open Source

Answer 1

I know this isn't a complete answer but node.js allows for c and c++ add-ons you could then grab the zpaq c++ source and try loading it into node.js as an add on. I haven't worked with c++ enough to help much more but that might be your best bet. Might require some tinkering and troubleshooting but I imagine it's possible

Answer 2

Not sure if this would work for you, but i'm developing a NodeJS wrapper for Uharc. Uharc is not paq, it is bsc. But it is free and it's 10% faster than paq4.

It uses wine to run in Linux and OSX as uharc is closed source and windows only.

Answer 3

Doesn't exists. There is currently only the cpp version.

According Google and the zpaq website at bottom which lists related projects

Or the zpaq updates thread:
