Module for dispatching jobs and timed operations
Project description
dispatch
Python package for timed dispatching of events or work
Usage
### The Reactor ###
from dispatch import Reactor
r = Reactor()
# The dispatch function needs two parameters, a schedule and an action
schedule = r.schedule_interval(seconds=2) # Run every 2 seconds
action = r.action(print, "hello") # Call the print function with the parameter "hello"
r.dispatch(schedule, action)
r.run()
### The Actions ###
# There are two helper functions that build actions based on functions:
r.action(func, parameter, parameter2, kwarg1=value) # Runs in main loop
r.background_action(func, parameter, parameter2, kwarg1=value) # Runs in new thread
### The Schedules ###
# A schedule is just an iterator that returns timestamps but there are
# several constructors included which make needing to write one rare
from datetime import datetime
# Run once on April 1st 2012 at 4 am
r.schedule_one_time(datetime(2020,4,1,4))
# Run on August 5th and 8th, 2020
timestamps = [datetime(2020, 8, 1), datetime(2020, 8, 5)]
schedule = iter(timestamps)
# To run at 8am and 5pm on Tuesdays and thursdays
r.schedule_calendar(days_of_week=["Tuesday", "Thursday"], hours=[8, 17])
# To run hourly on the 15th minute
r.schedule_hourly(minute=15)
# To run daily at 5:12 pm
r.schedule_daily(hour=17, minute=12)
# To run every hour and a half
r.schedule_interval(hours=1, minutes=30)
# To run every 26 hours till the year 2020
r.schedule_interval(days=1 hours=2, till=datetime(2020, 1, 1))
# To run on the 1st 5th, 10th, 15th, 20th, and 25th of the month @ midnight
r.schedule_calendar(days=[1,5,10,15,20,25])
# To run mondays on every hour
r.schedule_calendar(days_of_week=['Monday'], hours='*')
