The "backhead" was where the the gauges and controls sat on the old steam engines. This gem removes the tedium of defining rails engine configuration options
Include backhead into class. You can now define configuration options for your engine.
class MyEngine < Rails::Engine include configuration :my_engine do option :fast option :efficient end # standard engine stuff initializer 'my_engine.setup' do |app| MyEngine.enable_nitrus_mode() if app.config.my_engine.fast MyEngine.decrease_fuel_consumption() if app.config.my_engine.efficient end end
This will create two new configuration options that users can set in their environment files:
As a bonus, it will also allow users to set these configuration parameters via the environment
MY_ENGINE_EFFICIENT if they so choose. This gives more baked in
flexibility to control the app and runtime rather than via source control.
Configuration options that are explicitly set during initialization will take precedence over those specified by environment variables
