# Markov-Chains

Clojure library for playing with Markov chains.

## Usage

(use '[ray1729.clojure.markov.core :only '(build-markov-model build-markov-chain)])

(defn tokenize-line
  [s]
  "Split a line into word characters and append a trailing newline to the
  sequence"
  (when (seq s)
    (re-seq #"[\w\n]" (str s "\n"))))

(defn tokenize-file
  [f]
  "Split lines that begin with a lower-case letter into their component letters"
  (with-open [r (reader f)]
    (doall (apply concat (map tokenize-line (filter #(re-seq #"^[a-z]" %) (line-seq r)))))))
  
;; Build a 3-letter prefix map of /usr/share/dict-words
(def m (build-markov-model (tokenize-file "/usr/share/dict/words") 3))
  
;; Generate a random "word" using the prefix map
(apply str (take-while (partial not= "\n") (build-markov-chain m ["a" "b" "b"])))
