How to use on the website

1. Basic interface

In the HTML ‘<head>’

<script type="text/javascript" src="arc.min.js"></script>

Then, You can run arc-language in your javascript.

var arc_runner = ArcJS.context();
var res = arc_runner.evaluate("(+ 1 2 3 4)");
console.log(res); // 10
// FizzBuzz
var code = [
 "(prn 'Start_FizzBuzz)",
 "(for n 1 100",
 "  (prn (case (gcd n 15)",
 "         1 n",
 "         3 'Fizz",
 "         5 'Buzz",
 "         'FizzBuzz)))"].join("\n");
arc_runner.evaluate(code);  // 1, 2, Fizz ...

2. Auto loading interface

In the HTML ‘<head>’

<script type="text/javascript" src="arc.min.js"></script>
<!-- jQuery is required in arc-loader.js -->
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="arc-loader.js"></script>

Then, You can load arc files as follows.

<script type="text/arc" src="fizzbuzz.arc"></script>

fizzbuzz.arc

(def fizzbuzz (limit)
  (for x 1 limit
    (prn
      (aif (mappend [if (is 0 (mod x car._)) cdr._] '((3 Fizz) (5 Buzz)))
           (string it)
           x))))

Then you can do following

<script type="text/arc">
(fizzbuzz 3)
(fizzbuzz 100)
</script>
