AsyncEv: asynchronous event objects
AsyncEv leverages asyncio to create events that can be subscribed to and waited for.
Installation
pip install asyncev
Usage
import asyncio
import asyncev
from dataclasses import dataclass
# Create an event
@dataclass
class MyEvent(asyncev.Event):
value: str
# Create a listener
async def on_myevent(ev: MyEvent):
print(f"Got a MyEvent with the value {ev.value}!")
# also works for methods, with binds possible at init time.
class Listener:
def __init__(self, name: str):
self.name = name
asyncev.bind(MyEvent, self.on_myevent)
async def on_myevent(self, ev: MyEvent):
print(f"{self.name} got a MyEvent with the value {ev.value}!")
asyncev.bind(MyEvent, on_myevent)
# Emit event (requires a running asyncio event loop)
async def main():
jeff = Listener("Jeff")
asyncev.emit(MyEvent(value="hello"))
await asyncio.sleep(.1)
del jeff # cleanup of event listeners is automatic
asyncev.emit(MyEvent("goodbye"))
await asyncio.sleep(.1)
asyncio.run(main())
