/**
 * @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="https://github.com/google/code-prettify#for-which-languages-does-it-work">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>

    * constant like PR_PLAIN.  index_n-1 <= index_n, and style_n-1 applies to

    *
    * The stylePatterns is a list whose elements have the form
    * [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
    *
    * Style is a style constant like PR_PLAIN, or can be a string of the
    * form 'lang-FOO', where FOO is a language extension describing 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.
    *
    * Shortcut is an optional string of characters, any of which, if the first

 * Sub-class specialization of EventHandler base class.
 *
 * TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,
 * scheduled asynchroneously, avoiding recursive calls in the same tick.
 *
 * The task itself is implemented in `doTick`. It can be requested and called for single execution
 * using the `tick` method.
 *
 * It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
 * no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
 *
 * If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
 * and cancelled with `clearNextTick`.
 *
 * The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
 *
 * Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
 *
 * Further explanations:
 *
 * The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
 * only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
 *
 * When the task execution (`tick` method) is called in re-entrant way this is detected and
 * we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
 * task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).
