Example say_hello.py

import sys
from crog.crog import Crog

cron = Crog('helloworld', 15, 0) ## all days at 00:15
cron.user = 'herrer'

## Each lists represent 1 cronjob line with these parameters.
params = [['gerard'], ['ted']]


@cron.load(params=params)
## @cron.load() without params. 
def say_hello():
    if len(sys.argv) > 1:
        name = sys.argv[1]
        print('Hello %s'%name)

    else:
        print('Usage: %s <name>' % sys.argv[0])


if __name__ == '__main__':
    say_hello()

First execution

First execution create cronjobs file.

root@comuter# python say_hello.py
[crop] config file helloworld was created.
15 0 * * * herrer /root/app/say_hello.py gerard
15 0 * * * herrer /root/app/say_hello.py ted

Step to use

• Declare Crog object.
• Define user right for execution (default: 'root').
• Define params if script accept arguments (optionnal).
• Decorate main function with 'Crog.load' decorator.
• Execute your script first time (with root) to generate cronjobs config file.

Update cronjobs

Just change Crog object declaration and execute one more time your script.
