Ruby

String#word(Index):

I made a little method that allowed me to replace "String".split(" ")[index] with "String".word index. I know that this is relatively simple, but I still found it kinda neat.

<lang ruby> class String

def word(index)
 return self.split(" ")[index] if index.class != Range
 return self.split(" ")[index].join(" ")
end

end </lang>

And here's it in action. Note that I also implemented a renamed version; String#w(index): <lang ruby> dummy = "Hello my deary, dearsome, deareary, dearlicious and dearful dearies!"

dummy.word 3 #=> "dearsome," dummy.w 3 #=> "dearsome,"

dummy.word 0..-1 #=>"Hello my deary, dearsome, deareary, dearlicious and dearful dearies!" dummy.w 0..2 #=>"Hello my deary," </lang>

clear:

This was a clear-screen function, mainly for IRB environment in the UNIX terminal. In fact, there's already a UNIX command, clear that clears your screen. So, I tried this: <lang ruby> `clear` #=> "\e[H\e[2J" </lang> It was clearly an ANSI escape sequence. I did some more searching, and found herthis wonderful page.
