LibEx.Config

LibEx.Config exposes helpers around accessing OTP application configuration

Usage

Create a new module and use LibEx.Config passing the atom for the name of the application's configuration to wrap:

defmodule MyApp.Config do
  use LibEx.Config, application: :my_app

  defkey :db_host
  defkey :db_port
  defkey :db_user
  defkey :db_pass
end

Each defkey call maps to a setting you define in your mix file:

defmodule MyApp.Mixfile do
  def application do
    [
      env: [
        env:     :dev,
        db_host: "localhost",
        db_port: 5432,
        db_user: "postgres",
        db_pass: "postgres",
        db_name: "my_app"
      ]
    ]
  end
end

Now you can get the configured variables

MyApp.Config.db_host

Or set them

MyAppConfig.db_host("other_database_name")
