Hello everyone. I am experiencing an issue, which I am pretty sure is caused just by me not understanding stuff. Which is usual :slight_smile: I am currently writing a small package. Its only purpose is providing a few helper mix tasks. I want them to be configurable by the user through his Config…

Using application/0 :env for compile-time-only environment values seems at least strange. Why use :env instead of the config/config.exs though? And to answer your question more directly, as you see in documentation .app file is compiled after all Elixir files (as compile.app needs list of all modul…

I think Application — Elixir v1.20.2 could help you. I don’t spent many times on application but I think you miss mod def application do [ mod: {MyApp, []}, extra_applications: [:logger], env: [ foo: "bar" ]] end If someone could confirm (I don’t have my computer :/) Edit …

Yes, as far as i understand :mod key is for custom startup process. Like starting a supervision tree, etc. But, tbh, my app is more of a library and not an OTP app per se and i don’t really need custom start logic… In the same docs it is written Generally, build tools like Mix take care of start…

Sounds like it doesn’t read value from the function application in mix.exs. If you write it in any config file it works … Can’t find any mention of that behavior anywhere … Edit: add code bellow defmodule FooBar.Spam do @foo Application.fetch_env(:foobar, :foo) end Return :error, it seems the …

Thanks for the answers. But I still don’t understand. It seems like compile_env! just doesn’t work at all… Using fetch_env doesn’t help at all as it will just return :error. It will compile, yes, but the app still won’t be loaded and therefore values will still be empty. I just don’t understand w…

In fact it’s a « normal » behavior. You asked for a compiled env. but application/0 sounds like to be available only in runtime. So it doesn’t compile because you want a compiled env var that is not available. However I don’t know if it’s a normal that the ˋapplication/0` is not available in compi…

Okay, that makes sense now, thanks for the answer! Then, I am fixing my issue in the wrong way. I am writing a library and publishing it to hex. I want to make this library configurable I use compile env values throughout. But, as config.exs of my library won’t get published to hex as well as not a…

Hi, This is somewhat a workaround, but it seems to be working for me. I have my default configuration in the config/config.exs and adding following to the mix.exs: def application do [ ... env: Application.get_all_env(:my_app) ] end After I run mix compile there is my config in the e…
