acquire the shiny for your operating system from here:
http://www.ruby-lang.org/en/downloads/

open the interactive shiny! type irb in a terminal for linux and osx or open start > applications > ruby > fxri or something like that if you have the window one (like it says here: http://www.ruby-lang.org/en/documentation/quickstart/)

you might need to change to the directory where you glommed the string song to: type Dir.chdir ‘path/to/stringsong’ then press enter, where ‘path/to/stringsong’ is where it got put. single or double quotes both ok. the ruby interactive shiny should tell you ‘0’.

type require ‘apieceofstring’. this gloms the file into the interactive shiny. then you can play with it! :D

if you want song of sad, you can type GreatSong.new(‘sad’).sing
and it will sing for you sad song.

i did this and it looks a bit like this:

blodgett@home:~$ irb
irb(main):001:0> Dir.chdir ‘dl’
=> 0
irb(main):002:0> require ‘apieceofstring’
=> true
irb(main):003:0> GreatSong.new(‘fun!’).sing
