 | 
	
		
			
				|  |  | + * @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>
