What Hassan said, but something to consider is that this will change your
string in ways you don't necessarily want.


class String
  def title_format
     self.split.each{|element| element.capitalize! }.join(" ")
  end
end

string = "unexpected\n \tWhitespace"
string.title_format # => "Unexpected Whitespace"



# instead, I'd do it like this, which substitutes each run of non-whitespace
characters
# and substitutes them with their capitalized version
class String
  def title_format
    gsub(/\S+/) { |word| word.capitalize }
    # which can actually be shortened to: gsub(/\S+/, &:capitalize)
  end
end
string.title_format # => "Unexpected\n \tWhitespace"
