I want to flatten a map of nested maps/vecs Currently I'm using the fn's:
(defn- flatten-keys* [a ks m] (cond (map? m) (reduce into (map (fn [[k v]] (flatten-keys* a (if-not (empty? ks) (str ks "." (name k)) (str "$." (name k))) v)) (seq m))) (and (sequential? m) (not (instance? clojure.lang.MapEntry m))) (reduce into (map-indexed (fn [idx itm] (flatten-keys* a (str ks "[" idx "]") itm)) (seq m))) :else (assoc a ks m))) (defn flatten-keys [m] (flatten-keys* {} "" m)) (flatten-keys {:name {:first "Rich" :last "Hickey"} :number [1 415 123 4567]}) ;; => {"$.number[0]" 1, "$.number[1]" 415, "$.number[2]" 123, "$.number[3]" 4567, "$.name.first" "Rich", "$.name.last" "Hickey"} However, I was wondering if anyone had suggestions on a more performant fn? I have a white-list of possible flattened keys. But, the list is big (~1200), and with with most (~95%) of the keys having corresponding vals = nil it was much less performant using get-in on every possible key.
