I'm a programming newb trying to send a Ruby script/mini-game thing to his teacher that can be ran by doubleclick. JRuby seems like a possible solution, as does Warbler, but I can't seem to figure either of those out. It doesn't have to be a specific filetype if it can be run without the terminal, just by clicking on it. Another possible solution is creating a shell script that runs the file as shown here, but I think that only works if you tell the computer running the script that it can be doubleclicked. It may even be possible to run by doing something in the Ruby file itself, but I am too inexperienced to know.
Thanks in advance for your answers!
