GodScript is a project mainly written in Ruby, it's free.
Thou shall program in me.
This is a pet project which hopes allow programmers to expel their superiority into their code. For instance, the standard 'hello world' example:
Thou shall say 'hello world'.
Pretty sweet!
Navigate into the goscript directory and run:
ruby repl.rb
and then play around. Don't abuse your godly powers yet, though.
