Getting Started You can load the Prettify script to highlight code in your web pages. It adds styles to code snippets so that token boundaries stand out and your readers can get the gist of your code without having to mentally perform a left-to-right parse. Marking code sections The prettyprinter looks for

, , or <xmp> elements with the prettyprint class: source code here and adds s to colorize keywords, strings, comments, and other token types. If you're using Markdown or some other HTML generator that does not add classes, you can alternatively ask the prettifier to target your code by preceding it with a processing instruction thus: code here Larger example Auto-Loader You can load the JavaScript and CSS for prettify via one URL   will load the entire system and schedule the prettifier to run on page load. There are a variety of additional options you can specify (as CGI arguments) to configure the runner. | CGI parameter | default | meaning | |:------------------|:--------|:--------| | autoload=(true | false) | true | run automatically on page load | | lang=... | none | Loads the language handler for the given language which is usually the file extension for source files for that language. See the index of language handlers. If specified multiple times (?lang=css&lang=ml) then all are loaded. | | skin=... | none | See the skin gallery . If specified multiple times, the first one to successfully load is used. | | callback=js_ident | | window.exports["js_ident"] will be called when prettyprinting finishes. If specified multiple times, all are called. | For example   specifies the lang parameter to also load the CSS language extension and the skin parameter to load the sunburst skin. Serving your own JS & CSS You can download the scripts and styles and serve them yourself. Make sure to include both the script and a stylesheet:   and then run the prettyPrint function once your page has finished loading. One way to do this is via the onload handler thus:  Styling The prettifier only adds classes; it does not specify exact colors or fonts, so you can swap in a different stylesheet to change the way code is prettified. The easiest way to create your own stylesheet is by starting with one from the style gallery and tweaking it. You can use CSS @media rules to specify styles that work well with printers (for example, dark text on a white background) when someone tries to print it. Language Hints Prettify makes a best effort to guess the language but works best with C-like and HTML-like languages. For others, there are special language handlers that are chosen based on language hints. (friends 'of '(parentheses)) uses the lang-scm hint to specify that the code is Scheme code. (friends 'of '(parentheses)) also works. ## Line Numbering ## The linenums class in Many lines of code tells the prettyprinter to insert an 
 element and 
 elements around each line so that you get line numbers. Most stylesheets then hide the line numbers except for every fifth line. The class linenums:40 makes line numbering start at line 40 if you're excerpting a larger chunk of code, and lots of code also works.
