ruby code for modifying outer quotes on strings?

Question

Does anyone know of a Ruby gem (or built-in, or native syntax, for that matter) that operates on the outer quote marks of strings?

I find myself writing methods like

If you do it a lot, you may want to add a method to String:

class String
  def strip_quotes
    gsub(/\A['"]+|['"]+\Z/, "")
  end
end

Then you can just call string.strip_quotes.

Adding quotes is similar:

class String
  def add_quotes
     %Q/"#{strip_quotes}"/ 
  end
end

This is called as string.add_quotes and uses strip_quotes before adding double quotes.
