Sahnee.Config

Small helper library used inject a commonly used configuration pattern in projects at Sahnee.

Our configurations are typically isolated by module, meaning that config values relevant for module MyModule are set like:

config :your_app, MyModule,
  value1: true,
  value2: "hello world"

This library allows us to seamlessly use these values in MyModule

defmodule MyModule
  using Sahnee.Config, keys: [:value1, :value2]

  # Generates:
  defp env(key), do: Sahnee.Config.env(:your_app, key)
  defp env_value1(), do: env(:value1)
  defp env_value2(), do: env(:value2)
end

Allowing us to simply call the env_value1/0 function whenever we need to access this value without having to repeat the small, but quickly annoying boilerplate code.

Limitations

By design this library only allows to resolve runtime configuration values by using Application.fetch_env.
