Installation

pip install DocCron

Description

Cron-based scheduler inspired by doctest

Example

Cron jobs can be embedded into docstrings by using a literal block (::). Literal blocks should start with /etc/crontab.

Standard/Extended Format

Run hello() at every 2nd minute and 3rd minute:

import time


def hello():
    """
    Print "hello world" at every 2nd minute and 3rd minute:

    /etc/crontab::

        */2 * * * *
        */3 * * * *
    """
    print(time.strftime('%Y-%m-%d %H:%M:%S'), "hello world")


if __name__ == '__main__':
    import doccron
    doccron.run_jobs()

Quartz Format

Run hello() at every 2nd second and 3rd second:

import time


def hello():
    """
    Print "hello world" every 2nd second and 3rd second:

    /etc/crontab::

        */2 * * * * *
        */3 * * * * *
    """
    print(time.strftime('%Y-%m-%d %H:%M:%S'), "hello world")


if __name__ == '__main__':
    import doccron
    doccron.run_jobs(quartz=True)

Timezone-Awareness (CRON_TZ)

DocCron now support CRON_TZ. The value of CRON_TZ only applies to succeeding cron jobs. DocCron supports multiple CRON_TZ in a cron table. The default timezone value is the local/system timezone, if not specified.

import time


def hello():
    """
    Print "hello world" at every 2nd minute and 3rd minute:

    /etc/crontab::
    
        CRON_TZ=UTC
        */2 * * * *
        */3 * * * *
    """
    print(time.strftime('%Y-%m-%d %H:%M:%S%z'), "hello world")


if __name__ == '__main__':
    import doccron
    doccron.run_jobs()
