Hello,
I'm not seeing clearly what you're after.
Given your example, it seems that it can be solved just by the following code:
=> (def e1 [{:a 1 :b "b" :c 300 }{:a 2 :b "a" :c 500 }])
(def e2 [{:a 1 :d "blah"}{:a 2 :d "blah2"}])
#'user/e1
#'user/e2
=> (map merge e1 e2)
({:d "blah", :a 1, :b
user> (let [inputs (concat e1 e2)]
(map (partial apply merge)
(vals (group-by :a inputs
({:d "blah", :a 1, :b "b", :c 300} {:d "blah2", :a 2, :b "a", :c 500})

I wanted to merge ArrayMap in a vector. Is there a way to do that?
I put this together but wondering it there's already a library for
that.
(defn merge-by-field
"xt must have field vals unique"
[xs xt field]
(let [fmerge (fn [id s]
(merge s (first (filter #(= id (val (find % f
use (merge e1 e2)

(def e1 {:a 1 :b "b" :c 300 })
(def e2 {:a1 :d "blah"})
how to merge to get that?
{:a 1 :b "b" :c 300 :d "blah"}
also is there a way to merge if the ArrayMap was in a vector?
Thanks.
