mapsclj

(maps before after)

Find a difference between two maps. Returns a sequence of changes, which if applied in order transform map 'before' into map 'after' Maps could be nested.

Examples of basic changes: MapEntryDeleted{:key [:a], :value 1} MapEntryAdded{:key [:a :b :c], :value 10}

Can squash basic changes to detect more advanced changes: MapValueEdited{:key [:a], :value-from 1, :value-to 2} MapValueRenamed{:key-from [:a], :key-to [:b], :value 1}
