wilhelm-services

  • listen to AppicationContext for state events.
  • plugin configuration is programatic

Example:

# Create Manager instance
manager = Manager.new

# Set initial state
manager.disable

# Register service with application context
# note: environment is instance of Wilhelm::SDK::Environment
environment.register_service(:manager, manager)

There are several application context hooks that a service leverages to configure itself:

# lib/wilhelm/services/manager/service.rb

# Note: full namespaces have been ommitted for brevity

# called by application context on notify_observers
def state_change(new_state)
  case new_state
  # Endpoint is UART
  when Online

  when Offline
    # Endpoint is Log
  when Wilhelm::SDK::UserInterface::Context
    # UI Context has been created
    new_state
    .register_service_controllers(
      bluetooth: UserInterface::Controller::ManagerController
    )
  when Wilhelm::SDK::Notifications
    device_handler = Manager::Notifications::DeviceHandler.instance
    device_handler.manager = self
    new_state.register_handlers(device_handler)
  end
end
