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

Answer 1

I would use the value = value[1...-1] if value[0] == value[-1] && %w[' "].include?(value[0]). In short, this simple code checks whether first and last char of string are the same and removes them if they are single/double quote. Additionally as many as needed quote types can be added.

%w["adadasd" 'asdasdasd' 'asdasdasd"].each do |value|
  puts 'Original value: ' + value
  value = value[1...-1] if value[0] == value[-1] && %w[' "].include?(value[0])
  puts 'Processed value: ' + value
end

The example above will print the following:

Original value: "adadasd"
Processed value: adadasd
Original value: 'asdasdasd'
Processed value: asdasdasd
Original value: 'asdasdasd"
Processed value: 'asdasdasd"
