I had nearly forgotten all of the very convenient functions in the Medley
library <https://github.com/weavejester/medley> until I was reminded by a
small mention in the Clojure Cheatsheet
<http://jafingerhut.github.io/cheatsheet/clojuredocs/cheatsheet-tiptip-cdocs-summary.html>.
It allows you to very easily remove nil values from a list of maps and
merge them all together:
(ns clj.core
(:require [tupelo.core :as t]
[medley.core :as medley] ))
(t/refer-tupelo)
(def src [ {:a 1 :b nil}
{:c 3 }
{:d nil :e 5 } ] )
(spyx (apply glue src))
;=> (apply glue src) => {:a 1, :b nil, :c 3, :d nil, :e 5}
(spyx (medley/remove-vals nil? {:d nil :e 5}))
;=> (medley/remove-vals nil? {:d nil, :e 5}) => {:e 5}
(def result (medley/remove-vals
nil?
(apply t/glue src)))
(spyx result)
;=> result => {:a 1, :c 3, :e 5}
