I have a need to convert maps in the following ways:
Given a map with keyword keys, I need a map with uppercase string keys
- and vice versa.
{ :stuff 42 :like 13 :this 7 } <=> { "STUFF" 42 "LIKE" 13 "THIS" 7 }
I've come up with various functions to do this but so far they all
feel a bit clunky.
Any suggestions for the simplest, most idiomatic solution?
Here's one pair of functions I came up with...
(defn- to-struct [r] (apply hash-map (flatten (map (fn [[k v]]
[(s/upper-case (name k)) v]) r))))
(defn- to-rec [m] (apply hash-map (flatten (map (fn [[k v]] [(keyword
(s/lower-case k)) v]) m))))
s is clojure.string:
(:use [clojure.string :as s :only (lower-case upper-case)])
I came up with some using assoc and/or dissoc as well... didn't like
those much either :)
