-/**
- * @fileoverview
- * some functions for browser-side pretty printing of code contained in html.
- *
- * <p>
- * For a fairly comprehensive set of languages see the
- * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
- * file that came with this source. At a minimum, the lexer should work on a
- * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
- * XML, CSS, Javascript, and Makefiles. It works passably on Ruby, PHP and Awk
- * and a subset of Perl, but, because of commenting conventions, doesn't work on
- * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
- * <p>
- * Usage: <ol>
- * <li> include this source file in an html page via
- * {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
- * <li> define style rules. 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>

- * The stylePatterns is a list whose elements have the form

- * Style is a style constant like PR_PLAIN, or can be a string of the

- * language of the portion of the token in $1 after pattern executes.
- * E.g., if style is 'lang-lisp', and group 1 contains the text
- * '(hello (world))', then that portion of the token will be passed to the
- * registered lisp handler for formatting.
- * The text before and after group 1 will be restyled using this decorator
- * so decorators should take care that this doesn't result in infinite
- * recursion. For example, the HTML lexer rule for SCRIPT elements looks
- * something like ['lang-js', /<[s]cript>(.+?)<\/script>/]. This may match
- * '<script>foo()<\/script>', which would cause the current decorator to
- * be called with '<script>' which would not match the same rule since
- * group 1 must not be empty, so it would be instead styled as PR_TAG by
- * the generic tag rule. The handler registered for the 'js' extension would
- * then be called with 'foo()', and finally, the current decorator would
- * be called with '<\/script>' which would not match the original rule and
- * so the generic tag rule would identify it as a tag.
- *
- * Pattern must only match prefixes, and if it matches a prefix, then that
- * match is considered a token with the same style.
- *
- * Context is applied to the last non-whitespace, non-comment token
- * recognized.
