One of the most confusing topics when it comes to building Mix projects and releases is in figuring out the list of applications. The workflow for adding a dependency usually requires adding the dependency to the list of deps and then adding its application to the list of applications.
Since this was a common source of confusion, we wrote a blog post discussing the common scenarios and rationale: http://blog.plataformatec.com.br/2016/07/understanding-deps-and-applications-in-your-mixfile/ However, I believe we should still attempt to simplify this workflow. This is such a proposal. The idea is to automatically inflect the list of applications by including all dependencies that are required in production. Overall, we will have: def application do [otp_applications: [:logger], skipped_applications: [...], included_applications: [...]] end If the :applications key is is not provided, we will automatically inflect it by calculating: applications = ((all_apps_for_prod_deps ++ otp_applications) -- included_applications) -- skipped_applications - otp_applications - lists applications that come from erlang or elixir - skipped_applications - dependencies that are listed in production but you want to skip during releases (mutually exclusive with :applications) - included_applications - same meaning as today. applications you want to include in production but not start them I expect for the majority of cases developers won't need to pass the skipped_applications and included_applications flags, so we can skip them in generated templates. At the end, new apps will have only the following: def application do # List only applications from Elixir and Erlang required in prod [otp_applications: [:logger]] end Thoughts? *José Valim* www.plataformatec.com.br Skype: jv.ptec Founder and Director of R&D -- You received this message because you are subscribed to the Google Groups "elixir-lang-core" group.
