Reading Java properties file in Clojure

A simple and effective way to read properties files in Clojure, since they transform into Clojure maps!

(into {} (doto (java.util.Properties.)
         (.load (-> (Thread/currentThread)
         (.getContextClassLoader)
         (.getResourceAsStream "log4j.properties")))))

Next, to actually read this in, using atoms to swap the values like this seems to work,

(def *args* 
  (atom {:a 10, :b 20})) 

(defn -main [] 
  (swap! *args* assoc :a (read) :b (read)))
