Relative JSON Pointers #34

Open Julian opened 5 years ago

Julian commented 5 years ago

Hi!

Was wondering what you think about @handrews' Relative JSON Pointer specification.

Do you feel it has a place within this library, or would you rather it be separate?

(I ask of course because as in #20, I'm about to add support for validating relative JSON pointers to jsonschema).

Cheers, -J

As far as I can see from the specs, relative JSON pointers and ordinary JSON pointers can clearly be distinguished based on their first character, so an extension to this library should be possible.

@steinymity yes the intention of the original author (I just took it over to update it- it will get a new draft shortly which fixes a typo or two but nothing major) was that they were never ambiguous.

Well, so the only big hassle I see here is that relative JSON pointers need to be able to go to a parent object/array, but this "feature" is not available on standard dicts.

Maybe it makes sense to split the JSON pointer implementation in a data structure agnostic part (which just does parsing and validation) and an extendible part for a particular data structure, similar to pathlib's PurePath vs Path (and their subclasses).
