Non interactive ruby REPL for Sublime Text 2

instructions

1. Install Sublime REPL: https://github.com/wuub/SublimeREPL

2. Create a file "~/Library/Application Support/Sublime Text 2/Packages/SublimeREPL/config/Ruby Non Interactive/Main.sublime-menu" with the text below.

3. Please comment if you can get a shortcut to work for this. I haven't been able to yet.
