This project runs a mruby interpreter in a browser. It depends on webruby.

A live demo of this project is at http://qiezi.me/projects/mruby-web-irb/mruby.html. Feel free to try it!

How to build an interpreter

Build webruby using any gem configuration. But remember to use loading mode 2.

NOTE: If you do not know what is loading mode, feel free to ignore this since loading mode 2 is the default. However, a detailed description on loading mode is at here.
Copy the generated webruby.js file to current folder(and override existing file).
Now you are good to go!
