I'm new to Clojure, but with some lisp experience, I've dabbled in Scheme for a few years. Used Racket earlier this year for a couple of sectoins of a MOOC. And occasionally write Emacs lisp.
The idea is to create cyptograms <https://en.wikipedia.org/wiki/Cryptogram>. These are word puzzles using simple ciphers, and not meant for keeping real secrets. ;; -> (String -> String) ;; Returns a function that takes a string and produces a cryptogram. ;; Multiple calls to make-crypto will return different cryptos ;; each with different substitution keys. Multiple calls to a given ;; crypto returned by make-crypto will use the same substitution key. (defn make-crypto [] (let [lower (seq "abcdefghijklmnopqrstuvwxyz") upper (seq "ABCDEFGHIJKLMNOPQRSTUVWXYZ") digit (seq "0123456789") shuffled-lower (shuffle lower) shuffled-upper (shuffle upper) shuffled-digit (shuffle digit) encrypt (reduce conj (map (partial assoc {}) (concat lower upper digit) (concat shuffled-lower shuffled-upper shuffled-digit)))] (fn [s] (apply str (map #(encrypt % %) s))))) To me, it looks like too much code in defining the encrypt map. But I do not know how. -- Shannon -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
