unrar.js

A port of UnRAR to JavaScript using WebAssembly.

http://www.rarlab.com/rar/unrarsrc-5.5.3.tar.gz

!!!!!!!!!!!!!!!!!!!!!!

This project is just getting started, and does not work yet!

!!!!!!!!!!!!!!!!!!!!!!

Install WebAssembly:

git clone https://github.com/juj/emsdk.git
cd emsdk
./emsdk install sdk-incoming-64bit binaryen-master-64bit
./emsdk activate sdk-incoming-64bit binaryen-master-64bit

Build:

./make_web.sh

Run:

python3 -m http.server 8000

FIXME:

• Change to be a module, rather than emscripten main loop

• extract one file at a time

• Make a simple library for passing data between C++ and JS

• Remove vector, string to make wasm smaller

• Replace progress printing to console with callbacks

• Replace the Emscripten generated file with a simple example

• Passing between C++ and JavaScript is uber slow. As we pass it one byte at a time.

• It blocks when it does anything. Add functions for Web Workers.
