PersistConfig

Persists your configuration file and puts the app in module attribute :app or in one of your choice.

When your project is used as a dependency, this package will allow your config file to persist. For example, if you configured some path to read an external file and want to ensure you can still read the file even when your app is a dependency.

However you must include file config/config.exs in the package definition of your mix.exs file:

def project() do
  [
    app: :your_app,
    ...
    package: package(),
    ...
  ]
end
...
defp package() do
  [
    files: ["lib", "mix.exs", "README*", "config/config.exs"],
    maintainers: ["***"],
    licenses: ["***"],
    links: %{...}
  ]
end

Installation

Add the :persist_config dependency to your mix.exs file:

def deps() do
  [
    {:persist_config, "~> 0.1"}
  ]
end

Usage

use PersistConfig
@path Application.get_env(@app, :path)
...
{:ok, contents} = File.read(@path)
...

use PersistConfig, app: :my_app
@my_attr Application.get_env(@my_app, :my_attr)
