smart_sort() { |item| ... } click to toggle source

Sorts all items in this enumerable first by non-digits and then by digits.

If a block is given, it will be invoked to calculate the basis for comparison. Otherwise, the items themselves will be used as the basis for comparison.

    basis =
      if block_given?
        yield item
      else

      end.to_s

    alpha = basis.scan(/\D+/)
    digit = basis.scan(/\d+/).map(&:to_i)

    [alpha, digit]
