| /** |
| * This is similar to the lang-clj.js in JavaScript Prettify. |
| * |
| * All comments are adapted from the JavaScript Prettify. |
| * |
| * <p> |
| * Registers a language handler for Clojure. |
| * |
| * |
| * To use, include prettify.js and this file in your HTML page. |
| * Then put your code in an HTML tag like |
| * <pre class="prettyprint lang-lisp">(my lisp code)</pre> |
| * The lang-cl class identifies the language as common lisp. |
| * This file supports the following language extensions: |
| * lang-clj - Clojure |
| * |
| * |
| * I used lang-lisp.js as the basis for this adding the clojure specific |
| * keywords and syntax. |
| * |
| * "Name" = 'Clojure' |
| * "Author" = 'Rich Hickey' |
| * "Version" = '1.2' |
| * "About" = 'Clojure is a lisp for the jvm with concurrency primitives and a richer set of types.' |
| * |
| * |
| * I used <a href="http://clojure.org/Reference">Clojure.org Reference</a> as |
| * the basis for the reserved word list. |
