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>
