Subject: word_wrap method for String?


Hi all,

For a text adventure program I'm working on I needed a method to word 
wrap a long string based on spaces or non-word characters so I came up 
with this.  I just thought I'd post it to see if there are any thoughts 
or if there might be a better way to do it.

class String
  def word_wrap(width)
    source = self.dup
    original_width = width
    while width < source.length do
      last_space = source.rindex( / |\W/, width )
      source.insert( last_space, "\n" )
      source.gsub!(/\n */,"\n")
      width = last_space + original_width
    end
    source
  end
end
