A simple way to pretty print Clojure data/code to a file.

pretty-spit.clj

(require '[clojure.pprint :as pp]
         '[clojure.edn :as edn])

(def collection-to-print {:a 1
                          :b 2
                          :c 3
                          :d [1 2 3 4 5]})
(defn pretty-spit
  [file-name collection]
  (spit (java.io.File. file-name)
        (with-out-str (pp/write collection :dispatch pp/code-dispatch))))

;; write to EDN file
(pretty-spit "test.edn" collection-to-print)

;; try to read written file
(edn/read-string (slurp "test.edn"))

trying to read this using edn/read-string fails fwiw.

Hi,
It seems that the snippet was not functional at all. :-D
I have rewrotten it a bit and added a part with edn/read-string.
Cheers.
