TimerThread

TimerThread is

• A lightweight task scheduling timer
• written in Python (3.7+) Standard Library

TimerThread supports to

• schedule task execution after a given delay
• schedule recurring task execution
• run in the background
• use @task decorator to define task

Quickstart

Define your function, now(cost) as an example:

import time

def now(cost=1):
    time.sleep(cost)
    print( time.strftime('%Y-%m-%d %H:%M:%S %Z', time.localtime()) )

Create a TimerThread scheduler and start it:

import timerthread

timer = timerthread.Scheduler('recur', 3, now, args=(1,))
timer.start()

Shutdown the scheduler:

timer.cancel()

Play with the @task decorator

Use @task decorator to define your function, then schedule it and start the scheduler, now(cost) as an example:

import time
import timerthread

@timerthread.task('recur', 3)
def now(cost=1):
    time.sleep(cost)
    print( time.strftime('%Y-%m-%d %H:%M:%S %Z', time.localtime()) )

timer = now.sched(cost=1)
timer.start()

When you'd like to cancel the recurring execution, shutdown the scheduler as usual:

timer.cancel()

Install TimerThread

$ pip install timerthread

Documentation

Scheduler

class timerthread.Scheduler(trigger, interval, fn, args=(), kwargs={})

trigger must be 'delay' or 'recur'.

• stopped

  The scheduler is stopped or not, True (default) or False.

• result

  The execution result, {} as default.

• start()

  Let scheduler start executing your function as scheduled in the background.

• cancel()

  Shutdown the scheduler.

task

class timerthread.task(trigger, interval)

trigger must be 'delay' or 'recur'.

• Use @task decorator to define your function, then schedule it and start the scheduler:

  @timerthread.task(trigger, interval)
  def fn(args, kwargs):
      pass
    
  timer = fn.sched(*args, **kwargs)

  fn.sched(*args, **kwargs) returns timerthread.Scheduler instance.
