Elixir bindings for Binaryen

Installation

1. Add binaryen to your list of dependencies in mix.exs:

  def deps do
    [
      {:binaryen},
    ]
  end

Usage

First you'll need to install binaryen

brew install binaryen

Then compile some WebAssembly text format to bytecode:

# 99.wast

(module
(func $main (result i32)
  (i32.const 99))
(export "main" (func $main)))

-

wasm-as 99.wat 99.wasm

Now you can run it in Elixir!

{:ok, code} = File.read("99.wasm")
Binaryen.interpret(code)
