Hi, I've been dabbling with Clojure for a bit and I am really loving it!!! I am trying to write a clojure program to download a bunch of URLs and I was wondering what is the right way to do it - My current implementation is as follows
(def url-sequence (map #(str "http://www.mysite.com/list.php?pageID="; %) (range))) (def download (loop [urls url-sequence lst []] (let [ u (first urls) r (rest urls) resp (client/get u) next (re-find #"(s?)title=\"next page\">Next >>" (:body resp)) segments ((html2data (:body resp)) :segment) data (map segment2data segments) ] (if next (recur r (conj lst data)) (conj lst data))))) I was wondering if I could replace the loop thingy with a map - that is when I experimented with a simple piece of code and found something that was not intuitive. I'd really appreciate it if someone could tell me what's going on when I do the following - user> (defn xx [] (map println [1 2 3 4 5 6])) #'user/xx user> (take 2 (xx)) (1 2 3 4 5 6 nil nil) user> Regards, Kashyap -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
