Hi Meikel, I'm not sure I'm following your example, I ran this code (in Clojure 1.4) - it does not echo back the input and it does not seem to work lazily i.e. also hangs:
(defn -main [& args] ;; https://groups.google.com/d/msg/clojure/kYNWcfajHhY/5FcSk3B71mwJ (println "Input something:") (loop [lines (repeatedly read-line)] (let [line (first lines)] (println "You entered:" line) (when (not= "q" line) (recur (next lines)))))) Regards, Swaroop On Monday, July 2, 2012 1:16:37 PM UTC+5:30, Meikel Brandmeyer (kotarak) wrote: > > Hi, > > you wait for five lines.
