Re: Love the Medley library :)

[Colin Yates]

Thanks for the prompt to look at that again. I am not ashamed to say
that after doing Clojure full-time for years now, I still find value
in seeing other people's project.clj let alone their actual code :-).

Love the Medley library :)

[Alan Thompson]

I had nearly forgotten all of the very convenient functions in the Medley
library  until I was reminded by a
small mention in the Clojure Cheatsheet
.
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}
