module ConvenientService
  module Configs
    ##
    # Defines minimal configuration that adds a constructor, JSend-inspired result, steps, basic inspects, and internals to services.
    #
    # @note This config is NOT intented for the end-user usage. Use `Standard` instead.
    #
    # @note
    #   `use Plugins::Common::NormalizesEnv::Middleware` should be used in a config that has the first `concern` that introduces a method.
    #   For example, `:result` is added by `use Plugins::Service::HasJSendResult::Concern` in `Minimal`.
    #   That is why the following code is written in the `Minimal` config.
    #
    #     middlewares :result do
    #       use Plugins::Common::NormalizesEnv::Middleware
    #
    #       # ...
    #     end
    #
    #   In turn, `:fallback_result` is added by `use Plugins::Service::CanHaveFallback::Concern` in `Standard`.
    #   That is why it is the responsibility of the `Standard` config, to define:
    #
    #     middlewares :fallback_result do
    #       use Plugins::Common::NormalizesEnv::Middleware
    #
    #       # ...
    #     end
    #
    # @internal
    #   NOTE: Heavily used in specs to test concerns and middlewares in isolation.
    #
    module Minimal
      include Support::Concern

      ##
      # @internal
      #   IMPORTANT: Order of plugins matters.
      #
      #   NOTE: `class_exec` (that is used under the hood by `included`) defines `class Result` in the global namespace.
      #   That is why `class self::Result` is used.
