If you don't provide a storage file using --file, the default storage.json will be used in the current working directory. If --actions is not provided, the default actions folder will be copied to the current working directory, if it doesn't already exist.

Create an action

Examples of a standard action file and a complex action file can be found in the default_actions folder. A action is either a file that contains a class called Action which should use the base class ActionBase or a folder that contains a __init__.py file that contains the same class(es).

The evdev-trigger will call Action.execute with the input_device (Device class from evdev_trigger.models.devices) and the event (InputEvent from evdev.events).

Example of a simple action file:

from evdev_trigger.models import BaseAction


class Action(BaseAction):
    action_name: str = "EXAMPLE_DEBUG_ACTIONS"
    action_description: str = "Prints the device name, event code and value"

    def execute(self, input_device, event):
        """Execute the action"""
        print(f"[EVENT] {input_device.input_device.name}: {event.code} - {event.value}")
