It is unable to parse a bit complex ones.

I get the parsing error Failed to parse the following CRON expression: 0 9 1-7,15-21 * 1

A good example is a bi-weekly cron expression which is also fairly common => 0 9 1-7,15-21 * 1 see it here crontab.guru .

Hi there 👋

This is actually a duplicate of #18 but because it defines the problem more clearly, I'll keep this one and close the other one.

For now these patterns are recognised via regexes and so we would need one that can recognise all the different permutations of pattern taking into the account the operators' order of precedence.

It is on my pipeline to handle this issue but I'd be more than happy to accept a PR for this in the meantime.

The expected result for these permutations of patterns would be to count how many times per period they run.

For instance: 0 9 1-7,15-21 * * would be something like: 14 days a month, at 9am.

We loose a bit of information but this is done intentionally as this package is trying to output something that a human could quickly understand without having to read it multiple time. Of course other suggestions are welcome too. 🙂

Has anything been done to solve the problem? Other than shutting down the PR?
