Event type plugins¶

Type	`betty.ancestry.event_type.EventType`
Repository	`betty.project.Project.event_type_repository`

Event types are used to indicate the type of an Event, such as a birth, a death, or an marriage.

Creating an event type¶

Create a new class that extends betty.ancestry.event_type.EventType and implements the abstract methods, for example:

from typing import override
from betty.ancestry.event_type import EventType
from betty.machine_name import MachineName

class MyEventType(EventType):
  @override
  @classmethod
  def plugin_id(cls) -> MachineName:
      return "my-module-my-event-type"

  # Implement remaining abstract methods...
  ...

Tell Betty about your event type by registering it as an entry point. Given the event type above in a module my_package.my_module, add the following to your Python package:
```
[project.entry-points.'betty.event_type']
'my-module-my-event-type' = 'my_package.my_module.MyEventType'
```
