A Python event system
Project description
EVNTDispatch
EVNTDispatch is a versatile Python library designed to facilitate event-driven programming by providing a flexible event dispatcher. Whether you are building a graphical user interface, a command-line application, or a complex system with asynchronous components, the Event System simplifies communication and coordination between different parts of your code.
Key Features
-
Event Dispatching: Easily define and dispatch events to notify components of changes or user interactions.
-
Asynchronous Support: Seamlessly integrate asynchronous event listeners for efficient handling of time-consuming tasks without blocking the main execution.
-
Priority and Max Responders: Control the order of event listener execution and limit the number of responders for fine-grained control over event handling.
-
Task Scheduling: Schedule tasks to be executed after a specified delay, adding a layer of automation to your application.
Basic Async Example
import asyncio
from event_system.event_dispatcher import EventDispatcher, PEvent, EventType
dispatcher = EventDispatcher()
async def process_message(event: PEvent):
message_data, user_id = event.data
# Simulate processing the message, e.g., storing it in a database or applying business logic
print(f"Processing Message from User {user_id}: {message_data}")
await asyncio.sleep(1)
print("Message Processed")
async def send_message(user_id: int, message: str):
await dispatcher.async_trigger(PEvent("new_message", EventType.Base, data=(message, user_id)))
async def main():
dispatcher.start()
dispatcher.add_listener("new_message", process_message)
# Simulate users sending messages
task = [send_message(1, "Hello, how are you?"),
send_message(2, "I'm doing well, thanks!"),
send_message(1, "What's new?"),
send_message(3, "Not much, just relaxing.")
]
await asyncio.gather(*task)
await dispatcher.close()
if __name__ == "__main__":
asyncio.run(main())
