Building the controller DSL
To successfully call the use Goldcrest.Controller statement, we will need to define a __using__/1 macro in Goldcrest.Controller, which is responsible for injecting a controller-like behavior into a module.
Let’s start by simply moving the Plug.Builder call, the Plug.Conn call, and the call/2 function to the Goldcrest.Controller.__using__/1 macro:
defmodule Goldcrest.Controller do import Plug.Conn defmacro __using__(_) do quote do use Plug.Builder import Plug.Conn def call(conn, action: action) do conn = super(conn, []) apply(__MODULE__, action, [conn, conn.params]) end end end # .. end
In the previous code snippet...
