[![Downloads](https://pepy.tech/badge/async-cron)](https://pepy.tech/project/async-cron)
[![PyPI version](https://badge.fury.io/py/async-cron.svg)](https://badge.fury.io/py/async-cron)

this repo is influenced by schedule.

we supply a async scheduler and async function support

you can easily integrate this lib to you async program,with no blocking

## Install

--------------

pip install async-cron

## Usage examples

--------------


```python
import asyncio

from async_cron.job import CronJob
from async_cron.schedule import Scheduler


async def test(*args, **kwargs):
    print(args, kwargs)


def tt(*args, **kwargs):
    print(args, kwargs)


msh = Scheduler(locale="zh_CN")
myjob = CronJob(name='test', run_total=3).every(
    5).second.go(test, (1, 2, 3), name=123)
job2 = CronJob(name='exact', tolerance=100).at(
    "2019-01-15 16:12").go(tt, (5), age=99)
job3 = CronJob(name='very_hour').every().hour.at(
    ":44").go(tt, (5), age=99)

job3 = CronJob(name='hour').every().hour.at(
    ":00").go(tt, (5), age=99)
job4 = CronJob(name='minute').every(1).minute.go(tt, (5), age=99)
job5 = CronJob(name='weekday').weekday(2).at("11:18").go(tt, (5), age=99)
job6 = CronJob(name='monthday').monthday(16).at("11:22").go(tt, (5), age=99)
job7 = CronJob(name='monthday').every(5).monthday(
    16).at("11:22").go(tt, (5), age=99)


msh.add_job(myjob)
msh.add_job(job2)
msh.add_job(job3)
msh.add_job(job4)
msh.add_job(job5)
msh.add_job(job6)
msh.add_job(job7)

# jobload is only a special job,who gen jobs from config
# below means, this job load will check every 1 second for cron updates
# if any updates found,new job will be add to scheduler
# you dont have the direct way to delete jobs
# but you can modify the crons total_times to 0 or 1 to delete it
# by default,FileJobLoader use MultiThread,you can use MultiProcess by add
# thread=False

f_cron = FileJobLoader(name='f_cron', file_path='t_cron', log_path='.',thread=False)

fjob = CronJob(name='fjob', run_total=1).every(
    1).second.go(f_cron.run, msh)

msh.add_job(fjob)


loop = asyncio.get_event_loop()

try:
    loop.run_until_complete(msh.start())
except KeyboardInterrupt:
    print('exit')
```

## cron file useage:

parameter separate by blank.in item separate by comma

cron|name|job|env|run_times
-|-|-|-|-
`*/1,*,*,*,*`|test|/bin/python,tt.py|aa=123,bb=345|10

example as follow:

common cron

`*/1,*,*,*,*` test /bin/python,tt.py aa=123,bb=345 1

delete cron
`*/1,*,*,*,*` test /bin/python,tt.py aa=123,bb=345 0

cron only support:
 `*`,`10`,`*/10` format. which fulfills mostly screen
