trying to read some input

core.clj

(ns my-console.core)

(defn woot []
  (while true
    (print "cmd > ")
    (flush)
    (let [cmd (read-line)]
      (println "you entered:" cmd))))

(defn -main
  [& args]
  (woot))

Here's what happens. It doesn't print the input:

0:40:18 will@rautavaara my-console $  lein run                                                                      
echo> hi
^C%      

Might sound silly but, did you specify :main my-console.core in project.clj?

Yup, the problem here is that Leiningen is running Subprocess to launch your code, and that breaks input. So to make code like this work, you have to run lein trampoline run to quit the leiningen vm before launching your code.
