2. To check your answers: M-x 4clojure-check-answers
3. To open the next question (opens the first if you’re not in a 4clojure buffer): M-x 4clojure-next-question

Tips and Tricks

Start a cider/nREPL connection when you open a question

If you want to try out your solutions before you submit them, you can run them from emacs with cider. Make sure you have cider installed (M-x package-install cider) and add the following to your .emacs or init.el:

(require 'cider)

(defadvice 4clojure-open-question (around 4clojure-open-question-around)
  "Start a cider/nREPL connection if one hasn't already been started when
opening 4clojure questions"
  ad-do-it
  (unless cider-current-clojure-buffer
    (cider-jack-in)))
