Problem. In my Django application, users create tasks for scheduled execution. Users are pretty non-technical, and it would be great if they could write regular human-readable expressions to determine when to perform a specific task, for example:
- every Monday
- every fri, wed
- daily
- 1, 14, 20 of each month
- every Fri; every end of the month
It is inspired by Todoist . So far, only dates are needed; no time. I spent a couple of hours searching the library to do this, but no luck. I expect a function, say in_range(expression, date), such that:
>>> in_range('every monday, wednesday', date(2014, 4, 28))
True
>>> in_range('every end of month', date(2014, 5, 12))
False
>>> in_range('every millenium', date(2014, 5, 8))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: unknown token "millenium".
