Run.rb

Run.rb is a tool to run Ruby code inside the browser.

This project compiles Ruby to WebAssembly. Inside /src/emscripten you'll find (currently) Ruby 2.6.0 and the tooling required to compile Ruby to WASM.

This project was bootstrapped with Create React App, but then we ejected it for WebAssembly reasons.

Goals

  • Have an online interface to write and run Ruby code
  • Include the Ruby Standard Library
  • Add the ability to save "snippets" and share them
  • Provide JS libraries for run.rb supported versions of Ruby
    • Something like: <script src=“https://runrb.io/ruby-2.6.0”> and ruby(“yourcode”) // => Promise
  • You tell us

Compiling Ruby to WASM

To compile Ruby into WebAssembly, you'll need Docker installed.

In the project directory, you can run: make

Available scripts

To run the application locally, you'll need NodeJS and Yarn installed.

In the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn test

We sure could use some tests. 😉

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
