Workflow: filter based on file path

[martin-rueegg]

Situation

Context

When creating (work)flows, there are different filters that can be used in a rule, e.g. file name or file size, etc. However, there is no filtering possible on file path.

Use case

For example, on my mobile phone I upload pictures with AutoUpload to a specific folder on the server. Now I want to downsize all those pictures into another folder and saving the original in a different folder again, leaving the upload folder empty. I have a script for that. All I need to do is running that script whenever a new file is uploaded or moved into that folder.

Alternative?

While I can use a RegEx for example to match on the file extension (using the File name-filter), I cannot do the same for the path, as that information is not available (been cut off by basename()).

Solution

I have created a solution that works on NC17 (but needs review and might need some tweaks) and am now struggling to get it working on NC18+ (testing with 19.0.2). The main issue is, that while I have the filter in place, I don't manage to get it in the frontend into the list of available filters.

Help needed

Help on finalizing the patch would be great so that I can open a PR (guidance on the latter will also be appreciated once everything is ready).

PS: happy to provide a filter for #5330 as well, although I don't really see the use case on that.... :-)
