;; Be aware that prn-str and friends are influenced by a couple global variables ;; such as *print-length*: (set! *print-length* 10) (prn-str (range 15)) ;=> "(0 1 2 3 4 5 6 7 8 9 ...)\n" (set! *print-length* -1) (prn-str (range 15)) ;=> "(0 1 2 3 4 5 6 7 8 9 10 11 12 13 14)\n"

;; Also, set! cannot change the root binding for *print-length*. ;; Try the following instead. (def v [1 2 3 4 5 6 7 8 9 10]) (binding [*print-length* 5] (prn-str v)) ;;=> "[1 2 3 4 5 ...]\n" (binding [*print-length* -1] (prn-str v)) ;;=> "[1 2 3 4 5 6 7 8 9 10]\n"
