Example of a pipe implementation in a service, from the functional programming world 🤖

service.rb

class SomeService
  def call(some_value, bypass_some_method4 = false)
    pipe(
      some_value,
      :some_method1,
      :some_method2,
      -> (value) { value * 2 },
      bypass_some_method4 ? :noop : :some_method4,
      :some_method5
    )
  end

  private def pipe(initial, *methods)
    methods.reduce(initial) do |value, obj|
      case obj
      when Symbol
        method(obj).call(value)
      when Proc
        obj.call(value)
      end
    end
  end

  private def noop(value)
    value
  end
end
