Elixir: shortcut access to method/macro from another module

So, I have mix project, with module Uploader.Server and module Uploader.Utility.

Uploader.Utility defines request macro. Problem is that I can't access it like this in Uploader.Server, I can only call Uploader.Utility.request, which is very inconvinient, as server module provides shell interface and request is going to be a common argument for commands.

I can just put this macro in Uploader.Server module, but logically it does not belong there.

Can I somehow provide access to this macro Uploader.Server just by inner name, not outer, something like alias?

You're looking for Kernel.SpecialForms.import/2.

Example:

defmodule Uploader.Utility do
  defmacro request(name) do
    quote do
      def unquote(name)(), do: :ok
    end
  end
end

defmodule Uploader.Server do
  require Uploader.Utility
  import Uploader.Utility, only: [request: 1]

  request(:hello)
end

IO.inspect Uploader.Server.hello

prints

:ok
