Handling stdin Clojure -


the below doesn't seem work, i'm not quite sure why. move-board take in 2d array , return 2d array, rest of code there. i'm trying accomplish following python:

while true:   stuff   if gameover:     print("game over!")     break

clojure isn't working (prints board once, asks input, hangs)

(defn game-loop [board]   (loop [b board]     (if (game-over? b) "game over!"         (do (print-board b)             (recur (move-board (read-line) b))))))

we need see other functions doing. fabricated them minimally seems likely, , reindented make if-branch clearer. loop unnecessary.

(defn game-over? [b] false) (defn print-board [b] (println b)) (defn move-board [ln b] (println "moving board:" ln))  (defn game-loop [b]   (if (game-over? b)     "game over!"     (do (print-board b)         (recur (move-board (read-line) b)))))  (game-loop :bored)

with top 3 functions, loop behaves expected: prompting single line, infinitely. well, @ least first time, "hang" issue reproduced.

this being caused this issue jvm. discussed here.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
