chronous 1.2.1

Library for Event-Driven architecture using asyncio.

Chronous is a asynchronous python library designed to make asynchronous event-driven architectures on discord.py

[Example]

import asyncio
from typing import NoReturn
import datetime
from chronous.Architecture import BaseArchitecture
from chronous.events import EventContext, Setup, Init, Start, Close

class SampleArchitecture(BaseArchitecture):

  def __init__(self) -> None:
    super(SampleArchitecture, self).__init__(name="sample")

    # Registering events
    self.register_event(event=Setup())
    self.register_event(event=Init())
    self.register_event(event=Start())
    self.register_event(event=Close())

  def run(self) -> None:
    # Registering default lifecycle events
    # Start process.
    print("Starting process...")
    asyncio.run(self.process())

  async def process(self) -> NoReturn:
    await self.dispatch("setup")
    await self.dispatch("init")
    print('='*20)
    await self.dispatch("start", datetime.datetime.now())
    index: int = 0
    while index < 10:
      print("Looping!")
      index += 1
    await self.dispatch("close")
    print('='*20)


sample = SampleArchitecture()

# Multiple listener sample
@sample.listen()
async def setup(ec: EventContext):
  print("{e.name} phase - listener 1".format(e=ec.event))


@sample.listen()
async def setup(ec: EventContext):
  print("{e.name} phase - listener 2".format(e=ec.event))


# EventContext  sample
@sample.listen()
async def init(ec: EventContext):
  print("Initialization phase")
  print("Event : {e}".format(e=ec.event))


# Additional arguments sample
@sample.listen()
async def start(ec: EventContext, time: datetime):
  print("Starting process...")
  print("Starting at : {time}".format(time=time))


# Exception sample
@sample.listen()
async def close(ec: EventContext):
  print("Closing process...")
  print(f"Make an error : {1/0}")

sample.run()
