printing lazy lists
I am trying to dump a representation of the contents of a list to file. I've recently changed how I generated this list and it's now lazy (not really by design more by side-effect, if you will excuse the poor choice of words). I was using (spit file (str lst \n)) which worked quite nicely, but now it is failing. The problem is that I get a file full of clojure.lang.LazySeq@ lines. The problem comes from LazySeq directly, as this demonstration with range shows. user (str (list 1 2 3 4 5 )) (1 2 3 4 5) user (str (range 4)) clojure.lang.LazySeq@e1b83 user (println (range 4)) (0 1 2 3) nil println is using prn and a multimethod to print out. In fact, clojure.lang.LazySeq doesn't implement toString, nor does it's super class. The best solution that I have come up with so far is to do (str (apply list (range 4))) I guess I can see why LazySeq doesn't implement toString by printing everything out, but is there a better way around my problem?
