let's list of maps. maps have same keywords, don't know keywords beforehand.
[{:a 1 :b 2} {:a 3 :b 4}] and idiomatic way of merging list such map:
{:a [1 3] :b [2 4]} doesn't seem hard, start implement function, gets super ugly , repetitive. have feeling there cleaner ways of achieving this.
thank you
you can pretty elegant solution using several functions standard library:
(defn consolidate [& ms] (apply merge-with conj (zipmap (mapcat keys ms) (repeat [])) ms)) example:
(consolidate {:a 1 :b 2} {:a 3 :b 4}) ;=> {:a [1 3], :b [2 4]} one cool thing solution works if maps have different key sets.
