### 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](https://docs.python.org/3/library/sched.html). 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](https://pip.pypa.io/en/stable/installing/) to 
install it.

To install event scheduler, type the following command in the terminal:

`pip install event-scheduler`

To import the module, add the following lines in your Python file.

`from event_scheduler import EventScheduler`

To download directly visit [PyPi](https://pypi.org/project/event-scheduler/) or
the [GitHub repository](https://github.com/phluentmed/PythonEventScheduler).

## Documentation
Full documentation can be found [here](https://event-scheduler.readthedocs.io).
### 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. 

```python
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!`
\
`...`
