# warpy - WebAssembly in RPython

A WebAssembly interpreter written in RPython.

Warpy supports the WebAssembly MVP (minimum viable product) version of

the spec.

## Prerequisites

Build whe warpy executable. You will need a build of rpython on the

path:

```

make warpy-jit   # or make warpy-nojit

```

Alternatively, you can use an rypthon docker container (built

from Dockerfile-rpython) and do the compilation from there:

```

docker pull kanaka/warpy-rpython

docker run -it kanaka/warpy-rpython -v `pwd`:/build -w /build make warpy-jit

```

You will need `wast2wasm` to compile wast source to wasm bytecode.

Check-out and build [wabt](https://github.com/WebAssembly/wabt)

(wabbit):

```

git clone --recursive https://github.com/WebAssembly/wabt

make -C wabt gcc-release

```

## Usage

Compile a wasm module:

```

wast2wasm test/addTwo.wast -o test/addTwo.wasm

```

Load and call a function in a wasm module:

```

./warpy-jit test/addTwo.wasm addTwo 11 12

```

You can also use standard python (but it's much slower of course):

```

python warpy.py test/addTwo.wasm addTwo 13 14

```

There is also a REPL mode that allow you to interactively invoke

functions within a module:

```

./warpy-jit --repl test/addTwo.wasm

webassembly> addTwo 2 3

```

## Misc

Some rough notes for running the WebAssembly specification tests can

be found in `notes\_testing`.
