``crontools`` is a library that allows you to parse crontab expression and iterate over scheduled fire times.
Features:
- crontab expression parser
- optional seconds field support
- optional year field support
- crontab fire time sequential iteration support
Installation
------------
You can install crontools with pip:
.. code-block:: console
$ pip install crontools
Quickstart
----------
Get next cron fire time:
~~~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: python
>>> import datetime as dt
>>> import crontools as ct
>>>
>>> tz = dt.timezone.utc
>>> now = dt.datetime.fromisoformat('2020-02-29 23:59:59.999+00:00')
>>> ct = ct.Crontab.parse(
... '* * * * * * *',
... seconds_ext=True,
... years_ext=True,
... tz=tz,
... )
>>>
>>> print(f"Next fire time: {ct.next_fire_time(now=now)}")
Next fire time: 2020-03-01 00:00:00+00:00
Iteration over cron fire times starting from now:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. code-block:: python
>>> import crontools as ct
>>>
>>> tz = dt.timezone.utc
>>> now = dt.datetime.fromisoformat('2021-02-01 00:00:00+00:00')
>>> ct = ct.Crontab.parse(
... '30 30 12-16/2 1,2 JAN SAT,SUN *',
... seconds_ext=True,
... years_ext=True,
... tz=tz,
... )
>>>
>>> cron_iter = ct.iter(start_from=now)
>>> for n, fire_datetime in zip(range(1, 31), cron_iter):
... print("{n:2}: {dt}".format(n=n, dt=fire_datetime))
...
