Try this:

self.delete!("\n")
self.gsub!(/\s/,'')
self

Also, newlines are already included in \s so no need to have self.delete!("\n"). Simply do

class String
  def clean_text!
    self.gsub!(/\s/,'')
    self
  end
end

For add_sig, use << instead of +:

  def add_sig!
    self << "add sig"
  end
