json-prune[-fetch-response] properties with specific value

[rusty-snake]

It's the best place I could find to "request" a feature.

To my knowledge there is no way to remove properties based on their value.

Given the following JSON, I want to remove things.[-].thingtype:"table".

{ "things": [{"name": "Thing 1", "thingtype": "table"}, {"name": "Thing 2", "thingtype": "chair"}]}

It's discussed in past too. Will need concrete evidences that the feature is necessary to fix actual issues.

A while ago I've started work for JSONpath-like syntax, but this work got sidelined due to time. Maybe eventually I will be able to bring this to completion.

An example issue: uBlockOrigin/uAssets#23587 . Currently we are using complex regexes instead.

Thanks @gorhill ❤️

example.com##+js(json-edit-fetch-response, .things.[?.thingtype=="table"], , propsToMatch, url:/api/v1/foobar.json)

[rusty-snake]

Yeah, documentation for json-edit-fetch-response is still missing and overall documentation of "complex" scriptlets like json-* is just confusing.

[stephenhawk8054]

Yeah, they are still brand new scriptlets so we need to wait if they need improvements and become more matured before documenting.

Unlike json-prune- scriptlets, the second argument is not needed with all json-edit- scriptlets:

example.com##+js(json-edit-fetch-response, .things.[?.thingtype=="table"], , propsToMatch, url:/api/v1/foobar.json)
                                                                          ^^
                                                                          not needed

Hence:

example.com##+js(json-edit-fetch-response, .things.[?.thingtype=="table"], propsToMatch, url:/api/v1/foobar.json)

In json-prune- scriptlets, the second argument is used to test a condition, which is not needed for json-edit- scriptlets since the condition, if any, is part of the JSON path (the first argument).

@gorhill Hmm... We are using this filter in Experimental list

www.youtube.com##+js(trusted-json-edit-xhr-request, .context.client[?.clientScreen=="WATCH_FULL_SCREEN"].clientScreen="ADUNIT", /youtubei/v1/player?prettyPrint)

Do I need to add propsToMatch?

[gorhill]

No need for propsToMatch, works same as json-prune- for that parameter: if just URL is to be matched, just the URL pattern on its own is fine. Explicitly providing propsToMatch as with OP filter is also fine.
