How can you generate a sequence of numbers from 0 to n and back? Here is my try. user> (require '(clojure.contrib [math :as math])) nil user> (take 15 (let [n 3] (drop n (map #(math/abs (- (mod % (* n 2)) n)) (range) (0 1 2 3 2 1 0 1 2 3 2 1 0 1 2) -- You received this message because you

Hi, It looks like Oracle NUMBER types get mapped to BigDecimal in a result seq from clojure.java.jdbc. Is there an easy way to configure clojure.java.jdbc/ResultSet to map Oracle NUMBERS to doubles? The resultset-seq from https://github.com/clojure/java.jdbc/blob/master/src/main/clojure/clojure

I think ruby has nice string interpolation. You can put the following in a textfield that a user can modify This is a #{adjective} string. Then, you can take that string, put it in quotes and have ruby evaluate it as a string. What is the clojure way of doing something similar. Presenting som
