Create array of symbols

Question

Is there a cleaner way to do something like this?

%w[address city state postal country].map(&:to_sym) 
#=> [:address, :city, :state, :postal, :country]
         


        

Answer 1

The original answer was written back in September '11, but, starting from Ruby 2.0, there is a shorter way to create an array of symbols! This literal:

%i[address city state postal country]

will do exactly what you want.
