- * For a fairly comprehensive set of languages see the - * README - * 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. - *
- * Usage:
} and {@code } tags in your source with
- * {@code class=prettyprint.}
- * You can also use the (html deprecated) {@code } 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.

- * constant like PR_PLAIN. index_n-1 <= index_n, and style_n-1 applies to
- * all characters in sourceCode[index_n-1:index_n].
- *
- * 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
- * character, gurantee that this pattern and only this pattern matches.
