Overview

The Event Scheduler uses an internal thread to allow the application to schedule events to occur either ASAP or at a specified time in the future. Instead of blocking your application's main thread, you can concurrently run some lightweight tasks. We took some inspiration for the API design from the python library's scheduler. Unlike the native sched module, the Event Scheduler is always on and ready to accept events. Event Scheduler is completely thread-safe too!

Installing

You should already have pip installed if you're using python > 3.4. If you don't, please visit this link to install it.

Quick Start

event_scheduler.start()

Enable the event scheduler to start taking events

event_scheduler.stop(hard_stop=False)

Stop the event scheduler and its internal thread. Set hard_stop to True to stop the scheduler right away and discard all pending events. Set hard_stop to False to wait for all events to finish executing at their scheduled times.

event_scheduler.enter(delay, priority, action, arguments=(), kwargs={})

Schedule an event with a callable action to be executed after the delay. Events will be executed according to their delay and priority (lower number = higher priority). arguments holds positional arguments and kwargs hold keyword arguments for the action. Returns an event object which can be used to cancel the event.

event_scheduler.cancel(event)

Cancel the event if it has not yet been executed.

event_scheduler.cancel_recurring(event_id)

Cancel the recurring event and all future occurrences.

from event_scheduler import EventScheduler

event_scheduler = EventScheduler()
# Starts the scheduler
event_scheduler.start()
# Schedule an event that prints a message after 5 seconds
event_scheduler.enter(5, 0, print, ('5 seconds has passed since this event was entered!',))
# Schedule a recurring event that prints a message every 10 seconds
event_scheduler.enter_recurring(10, 0, print, ('10 second interval has passed!',))

Output:
5 seconds has passed since this event was entered!
10 second interval has passed!
10 second interval has passed!
