These allow for actions like extracting the creation date from the original filename. See the rule "Parse creation date from filename" in example.yml for an example use case.

At first I thought this would add unnecessary complexity, but actually this makes things even more powerful. I like it a lot! Thanks for your contribution!

Hi, I want to use regex_sub to extract time information from filenames. But this function is not working for me, same for example.yml. I tried in the metadata_postprocessing section:

yy: '{{ "2099-05-4-kaese" | regex_sub(".(\d{4}).","\1") }}' title: 'test-{{yy}}-end'

There's no error in webserver's log but document arrves in paperless as 'test--end' I also tried to use re.sub directly, as far as I understood jinja this could be feasible?!?

Any idea?

Best regards Rüdiger
