-/** |
- * @fileoverview |
- * Registers a language handler for Haskell. |
- * |
- * |
- * 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-hs">(my lisp code)</pre> |
- * The lang-cl class identifies the language as common lisp. |
- * This file supports the following language extensions: |
- * lang-cl - Common Lisp |
- * lang-el - Emacs Lisp |
- * lang-lisp - Lisp |
- * lang-scm - Scheme |
- * |
- * |
- * I used http://www.informatik.uni-freiburg.de/~thiemann/haskell/haskell98-report-html/syntax-iso.html |
- * as the basis, but ignore the way the ncomment production nests since this |
- * makes the lexical grammar irregular. It might be possible to support |
- * ncomments using the lookbehind filter. |
