clj-coffee-script

clj-coffee-script is a Clojure wrapper for compiling CoffeeScript source files into JavaScript.

Usage

(require '[coffee-script.core :as cs])

;; Compiles the CoffeeScript string "number = 42" into its
;; JavaScript form:
;; 
;;            (function() {
;;              var number;
;;              number = 42;
;;            }).call(this);
;;
(cs/compile-coffee "number = 42")

;; Compiles the CoffeeScript string "x = [1,2,3]" into its
;; JavaScript form.  The CoffeeScript compiler is passed the
;; optional options map as a JSON string, in this case without the
;; top-level function safety wrapper:
;;
;;          var x;
;;          x = [1, 2, 3];
;; 
(cs/compile-coffee "x = [1,2,3]" {:bare true})

;; If there is a problem with the built-in CoffeeScript compiler,
;; you can use an external version of the compiler by using the
;; with-coffee-compiler macro.  Simply pass it a variable that
;; can be coerced into a reader via clojure.java.io/Reader.
;;
(with-coffee-compiler (clojure.java.io/file "/path/to/coffee-script.js")
    (cs/compile-coffee "number = -42 if opposite"))

;; The default compiler options can be changed by binding the
;; *default-coffee-options* symbol to a different value.
(with-binding [*default-compile-options* {:bare true}]
    (cs/compile-coffee "square = (x) -> x * x"))
