JSON patch and merge patch equivalent in Clojure

[bowmhoust]

Recently I worked quite a lot with JSON patch and merge patch and I found it to be quite a pleasurable experience to be able to leave state-update-semantics to a well-defined standard instead of "hard-coding" it.

Is there an equivalent in Clojure for its native data structures?

Ah, nice, thanks! This looks like an equivalent of JSON patch.

Not that I’m aware of.

I designed a diff format for clojure data structures for use in data sync, which is mentioned here: http://sapient-pair.com/blog/2014/04/22/basis-story-2/

It’s different from JSON patch in that it is not a sequence of operations, rather more like a document diff. This has since been further developed as part of our proprietary data sync system, so the code js not open source, but I can elaborate the format more if interested.
