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

Please try OCG options combination generator.

require "ocg"

generator = OCG.new(
  :bitrate => %w[100 500 1000],
  :fps => %w[15 30],
  :qp => %w[20 30]
)

puts generator.next until generator.finished?

Generator includes much more functionality that will help you to deal with other options.
