Does conform work without release? about conform

[lswith]

This is something I think should be put on the main documentation. It seems it doesn't say anywhere that conform doesn't work out of the box with mix run --no-halt.

I like to know as well if there is a way to use conform outside of releases. To have a single way to configure our application would be nice!

Let me share what I have found so far. Both Elixir as well as Ecto has implemented init callback. For example Ecto repo definition can now looks like:

defmodule MyApp.Repo do
  use Ecto.Repo, otp_app: :my_app
  def init(_, config) do
    {:ok, Keyword.put(config, :url, System.get_env("DATABASE_URL"))}
  end
end

So this could be on one of places, where one can extract app level configuration from conform and shove it back to appconfig. But to be honest, I am still not really sure, if this is the right approach.

Quite interesting thread at elixir-forum - https://elixirforum.com/t/always-use-releases/4573/18
