Common errors

error ModuleNotFoundError: No module named 'pyeventsystem' ↓

cause Package not installed or installed in wrong environment.

fix

Run 'pip install pyeventsystem' in the correct Python environment.

error ImportError: cannot import name 'EventSystem' from 'pyeventsystem' ↓

cause The API may not match the expected import; check the exact exported names.

fix

Use 'from pyeventsystem import *' or examine the module's __init__.py for correct symbols.

Warnings

gotcha Library is very early stage (v0.1.0). API is unstable and likely to change. Do not rely on it for production without careful version pinning. ↓

fix Pin exact version in requirements.txt and test thoroughly before upgrading.

gotcha The decorator '@event_handler' is not explicitly documented; may not exist or may be called differently. The README shows minimal examples. ↓

fix Check the source code or README for the correct decorator name (likely 'app.handler' or similar).

gotcha No documentation for middleware ordering or priority. Middleware execution order may be undefined. ↓

fix Review source code or test middleware behavior manually.

Quickstart

Create an EventSystem, add middleware, define handlers, and emit events.

from pyeventsystem import EventSystem, Event

app = EventSystem()

@app.middleware('before')
def logging_middleware(event):
    print(f'Before event: {event.name}')

@event_handler
def my_handler(event):
    print(f'Handling {event.name}')

app.emit(Event('test'))
