Why do you want to alias all modules? What are you aiming to do?

I came up with this code block that allows me to load all project aliases for the quick terminal usage

defmodule Console do
  defmacro aliases(expression) do
      {:ok, modules} = :application.get_key(:<YOUR_APP>, :modules)
  
      modules =
        for module <- modules do
          quote do
            alias unquote(module)
          end
        end
  
      quote do
        unquote(modules)
        unquote(expression)
      end
  end
end

So now I can execute something like this:

iex(10)> require Console
iex(11)> Console.aliases Repo.all(Room)
[
  %Tarragon.Battles.Room{
    __meta__: #Ecto.Schema.Metadata<:loaded, "battle_rooms">,
    id: 1,
...
