module Maquina
  module Navbar
    # == Desktop profile menu at Navbar
    #
    # Renders dropdown profile menu on desktop.
    #
    # Requires Rails Helper method to get access to options for this menu. Method `profile_menu_options` example:
    #
    #   def profile_menu_options
    #     if Current.user.present?
    #       {
    #         profile: profiles_path
    #         signout: { method: :delete, path: session_path }
    #       }
    #     else
    #       {
    #         signin: new_session_path
    #       }
    #     end
    #   end
    #
    # `ProfileMenu` uses I18n to translate menu options. Translation example:
    #
    #   menu:
    #     profile:
    #       profile: My profile
    #       signout: Close session
    #       signin: Login
    #
    # `ProfileMenu` is initialized by default to render links for desktop. To render mobile links,
    # initialize `ProfileMenu` as follow:
    #
    #   Views::Navbar::ProfileMenu.new(desktop: false)
    #
    class ProfileMenu < Phlex::HTML
      include ApplicationView
      delegate :t, :profile_menu_options, to: :helpers
