All possible combinations from a hash of arrays in Ruby

Question

What I have:

Let\'s say I have a hash like this, with various values belonging to one parameter.

a = {}
a[:bitrate] = [\"100\", \"500\", \"1000\"]
a[:f         


        

Answer 1

Just FYI I took fl00r's approach and monkey-patched it. I like it a bit better.

class Hash
  def product
    product = values[0].product(*values[1..-1])
    product.map{|p| Hash[keys.zip p]}
  end
end
