MWC

The tool for the developer to help them create mruby applications on the WebAssembly.

Add this line to your application's Gemfile:

gem 'mwc'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mwc

• Curl
• Tar
• Emscripten SDK
• Ruby 2.6+

Please make sure you can execute emcc before use mwc compile

Execute below command with your project name:

$ mwc init my_mrb

This gem will create a directory my_mrb with anything you need to play with mruby on WebAssembly.

• src/**/*.c the normal C code
• src/js/**/*.lib.js the JavaScript library can be called in C
• src/js/**/*.pre.js the JavaScript prepend to WebAssembly JS
• src/js/**/*.post.js the JavaScript append to WebAssembly JS

To compile *.c to .wasm you have to execute compile command:

$ mwc compile

You can specify compile environment to change with different options:

$ mwc compile --env=dev

To see more usage with help command:

$ mwc help compile

The mwc has built-in static file server to help preview or debug:

$ mwc server

And then, open the http://localhost:8080 you will see the Emscripten web shell and Hello World is printed.

We use DSL to define the compile preferences in .mwcrc

project.name = 'mruby'
mruby.version = '2.1.3'

env :dev do
  project.source_map = true
end

• Unit Test
• Download options for mruby
  • Archive
  • Git Submodule
• Integrate to Webpack
• Watch Mode
  • Auto re-compile
  • Add LiveReload support

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
