How to clear terminal screen in Clojure

Print some ANSI characters
(print (str (char 27) "[2J")) ; clear screen
(print (str (char 27) "[;H")) ; move cursor to the top left corner of the screen

Unfortunately, the cursor moving ANSI hasn't worked in any console I've tried it in (including the native Window's console). I had to resort to using this hack function:

(defn move-cursor-to [x y]
(let [r #(apply str (repeat % %2))]
(print (str (r y \newline)
(r x \space)))))
