I’m trying to create some translations for my CMS resources, and I’m trying to automatically create Gettext domains for each resource.

defmodule MyApp.Projects.Project do
  use B.Blueprint
  import MyApp.Gettext

  @singular "project"
  @plural "projects"

  # these macros basically build a map of translations
  translations do
    context :fields do
      translate :title do
        label t("Some label text")
        placeholder t("Some placeholder")
      end
    end
  end
end

The t macro lives in the used B.Blueprint and looks like this:

 # ...
  # 
  defmacro t(msgid) do
    quote do
      dgettext(@plural, msgid)
    end
  end

This doesn’t work of course:

** (ArgumentError) Gettext macros expect translation keys (msgid and msgid_plural),
domains, and comments to expand to strings at compile-time, but the given domain
doesn't. This is what the macro received:

{{:., [], [{:__aliases__, [counter: {MyApp.Projects.Project, 58}, alias: false], [:Module]}, :__get_attribute__]}, [], [{:__MODULE__, [counter: {MyApp.Projects.Project, 58}], Kernel}, :plural, 83]}

Is this doable in any way? I was hoping to not having to put all my translations in the “default.pot” file, and also not having to do t("projects", "msg here")
