The code we worked on near the end:

(def get-command-grammar
  '{:target (<- (some (range "az")))
    :get "get "
    :main (* :get :target)})

(defn process-command []
  (def input (file/read stdin :line))
  (print "The command was: " input)
  (pp (peg/match get-command-grammar input))

  # Recursive loop!
  (process-command))

(defn main
  [& args]
  (process-command))
