See the example page for examples. * <li> mark the {@code <pre>} and {@code <code>} tags in your source with * {@code class=prettyprint.} * You can also use the (html deprecated) {@code <xmp>} tag, but the pretty * printer needs to do more substantial DOM manipulations to support that, so * some css styles may not be preserved. * </ol> * That's it. I wanted to keep the API as simple as possible, so there's no * need to specify which language the code is in, but if you wish, you can add * another class to the {@code <pre>} or {@code <code>} element to specify the * language, as in {@code <pre class="prettyprint lang-java">}. Any class that * starts with "lang-" followed by a file extension, specifies the file type. * See the "lang-*.js" files in this directory for code that implements * per-language file handlers. * <p> * Change log:<br> * cbeust, 2006/08/22 * <blockquote> * Java annotations (start with "@") are now captured as literals ("lit") * </blockquote> * @requires console */ // JSLint declarations /*global console, document, navigator, setTimeout, window, define */ /** * Split {@code prettyPrint} into multiple timeouts so as not to interfere with * UI events. * If set to {@code false}, {@code prettyPrint()} is synchronous. */ window['PR_SHOULD_USE_CONTINUATION'] = true;
