re-purposed #239 for this issue. closing this one as duplicate. thanks!

[collinbarrett]

@KonoromiHimaries oh, I understand now what you meant about "WYMAGANE" (translates to "required"). are these other lists truly required for the MajkiIT lists to work? or are they recommended but not actually required?

We currently don't have a model for how to display required list prerequisites, but that might be something we need to support.

@collinbarrett These lists in column „wymagane" are truly required.

[collinbarrett]

FilterLists should have a relationship model for list prerequisites. Some lists, like the Polish lists referenced in this original issue, have a requirement that other lists also be subscribed to for them to function properly. FilterLists should index this relationship and display it to site visitors so that they are aware of these requirements.

@collinbarrett tan you remove "Official Polish Filters for AdBlock, uBlock Origin & AdGuard - Test Supplement" it's test file and have many mistakes.

Closing as will be addressed in #202 when capturing Pre-Processor Directives.

[collinbarrett]

Oh, this is different from Pre-Processor Directives. Re-opening.

[collinbarrett]

Work in progress.

Wiki page added: https://github.com/collinbarrett/FilterLists/wiki/Dependent

[collinbarrett]

The data model is now in place with an example per https://github.com/collinbarrett/FilterLists/commit/340d9c7825f6d237c0e6c4725e459641d179eb7c . Opened #465 to actually display this data in the UI, but now PRs can be submitted adding list dependents/dependencies.

A dependent is a list that is dependent on another list.
A dependency is a list that is a prerequisite of a dependent list.
