Defined in:
lib/app.rb

Overview

Provides configuration via superclass. Inherit from Configurable, and you have a handy little DSL/class for assigning/accessing your app settings.

class App < Configurable
  config.launched_at = Time.now.utc
end

App.launched_at # => 2010-02-21 12:34:56 UTC

Configurable classes will warn you when you call undefined settings.

App.typo # => nil
warning: undefined setting `typo' for App:Class

If you don’t care about these warnings, just redefine the logger.

App.configure do
  config.logger = Logger.new nil
end
