        ['gift', 'encoding'].each do |param|
          eval <<EOC
          task["active_#{param}"]=="on" ? active_#{param} = true : active_#{param} = false
          task["active_#{param}"] = active_#{param}
          active_#{param} = true if task["active_#{param}"]
          task, #{param} = separate_#{param}(task)
EOC
        end
        puts "#{active_gift} active_gift"
        puts "#{active_encoding} active_encoding"

initial code was

task["active_gift"]=="on" ? active_gift = true : active_gift = false
task["active_gift"] = active_gift
active_gift = true if task["active_gift"]
task, gift = separate_gift(task)
