str =<<EOS
hello hello hello hello hello hello hello hello hello hello hello hello 
hello hello
goodbye goodbye goodbye goodbye
EOS

class String
  def word_wrap(line_width = 80)
    self.gsub(/(.{1,#{line_width}})(\s+|$)/, "\\1\n")
  end
end

puts str.word_wrap

--output:--
hello hello hello hello hello hello hello hello hello hello hello hello 
hello
hello
goodbye goodbye goodbye goodbye
