+ * Extends XRegExp syntax and allows custom flags. This is used internally and can be used to
+ * create XRegExp addons. If more than one token can match the same string, the last added wins.
+ * @memberOf XRegExp
+ * @param {RegExp} regex Regex object that matches the new token.
+ * @param {Function} handler Function that returns a new pattern string (using native regex syntax)
+ *   to replace the matched token within all future XRegExp regexes. Has access to persistent
+ *   properties of the regex being built, through `this`. Invoked with three arguments:
+ *   <li>The match array, with named backreference properties.
+ *   <li>The regex scope where the match was found: 'default' or 'class'.
+ *   <li>The flags used by the regex, including any flags in a leading mode modifier.
+ *   The handler function becomes part of the XRegExp construction process, so be careful not to
+ *   construct XRegExps within the function or you will trigger infinite recursion.
+ * @param {Object} [options] Options object with optional properties:
+ *   <li>`scope` {String} Scope where the token applies: 'default', 'class', or 'all'.
+ *   <li>`flag` {String} Single-character flag that triggers the token. This also registers the
+ *     flag, which prevents XRegExp from throwing an 'unknown flag' error when the flag is used.
+ *   <li>`optionalFlags` {String} Any custom flags checked for within the token `handler` that are
+ *     not required to trigger the token. This registers the flags, to prevent XRegExp from
+ *     throwing an 'unknown flag' error when any of the flags are used.
+ *   <li>`reparse` {Boolean} Whether the `handler` function's output should not be treated as
+ *     final, and instead be reparseable by other tokens (including the current token). Allows
+ *     token chaining or deferring.
+ * @example
+ *
+ * // Basic usage: Add \a for the ALERT control code
+ * XRegExp.addToken(
+ *   /\\a/,
+ *   function() {return '\\x07';},
+ *   {scope: 'all'}
+ * );

+ * XRegExp.addToken(
+ *   /([?*+]|{\d+(?:,\d*)?})(\??)/,
+ *   function(match) {return match[1] + (match[2] ? '' : '?');},

+ *   `alias`, `isBmpLast`, `inverseOf`, `bmp`, and `astral`. All but `name` are optional, although
+ *   one of `bmp` or `astral` is required (unless `inverseOf` is set). If `astral` is absent, the
+ *   `bmp` data is used for BMP and astral modes. If `bmp` is absent, the name errors in BMP mode
+ *   but works in astral mode. If both `bmp` and `astral` are provided, the `bmp` data only is used
+ *   in BMP mode, and the combination of `bmp` and `astral` data is used in astral mode.
+ *   `isBmpLast` is needed when a token matches orphan high surrogates *and* uses surrogate pairs
+ *   to match astral code points. The `bmp` and `astral` data should be a combination of literal
+ *   characters and `\xHH` or `\uHHHH` escape sequences, with hyphens to create ranges. Any regex
+ *   metacharacters in the data should be escaped, apart from range-creating hyphens. The `astral`
+ *   data can additionally use character classes and alternation, and should use surrogate pairs to
+ *   represent astral code points. `inverseOf` can be used to avoid duplicating character data if a
+ *   Unicode token is defined as the exact inverse of another token.

+/**
+ * @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 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.

+// This is not a normal parser design; it's basically just a

+// maintain this way,  but keeping Showdown close to the original
+// design makes it easier to port new features.
+//
+// More importantly, Showdown behaves like markdown.pl in most
+// edge cases.  So web applications can do client-side preview
+// in Javascript, and then build identical HTML on the server.
+//
+// This port needs the new RegExp functionality of ECMA 262,
+// 3rd Edition (i.e. Javascript 1.5).  Most modern web browsers
+// should do fine.  Even with the new regular expression features,
+// We do a lot of work to emulate Perl's regex functionality.

+// label.  Major or self-explanatory changes don't.
+//
+// Smart diff tools like Araxis Merge will be able to match up
+// this file with markdown.pl in a useful way.  A little tweaking
+// helps: in a copy of markdown.pl, replace "#" with "//" and
+// replace "$text" with "text".  Be sure to ignore whitespace
+// and line endings.
