Compile your CoffeeScript along with your Clojure

gistfile1.clj

;;; Compile your CoffeeScript along with your Clojure

;; NOTE: For Clojure projects using Leiningen 1.7.x.
;;       Instructions for Leiningen 2.0.x coming soon.

;; Step 1: add [robert/hooke "1.1.2"] to the :dev-dependencies option of your defproject call

;; Step 2: add the following code to the bottom of your project.clj:

(require ['robert.hooke :as 'hooke]
         ['leiningen.compile]
         ['clojure.java.io :as 'io]
         ['clojure.java.shell :as 'shell])

;; hook to compile Coffeescript before Leiningen does stuff
(hooke/add-hook #'leiningen.compile/eval-in-project
  (fn [eip & args]
    (let [compiler-path "/usr/local/bin/coffee"   ; adjust for your system
          coffee-dir    "resources/public"        ; adjust for your project
          shell-args    [compiler-path "-c"]
          coffee-files  (->> (io/file coffee-dir)
                             (.listFiles ,,,)
                             (map #(.getPath %) ,,,)
                             (filter #(.endsWith % ".coffee") ,,,))
          result        (apply shell/sh (concat shell-args coffee-files))]
      (apply println (if (= (:exit result) 0)
                         (concat ["Compiled"] (interpose ", " coffee-files))
                         ["Error invoking CoffeeScript compiler:" result])))
    (apply eip args)))
