+ </head>
+ <body bgcolor="white">
+ <a style="float:right" href="README.html">README</a>
+
+ <h1>Known Issues</h1>
+ <ul>
+ <li>Perl formatting is really crappy. Partly because the author is lazy and
+ partly because Perl is
+ <a href="http://www.perlmonks.org/?node_id=663393">hard</a> to parse.
+ <li>On some browsers, <code>&lt;code&gt;</code> elements with newlines in the text
+ which use CSS to specify <code>white-space:pre</code> will have the newlines
+ improperly stripped if the element is not attached to the document at the time
+ the stripping is done. Also, on IE 6, all newlines will be stripped from
+ <code>&lt;code&gt;</code> elements because of the way IE6 produces
+ <code>innerHTML</code>. Workaround: use <code>&lt;pre&gt;</code> for code with
+ newlines.
+ </ul>
+
+ <h1>Change Log</h1>
+ <h2>29 March 2007</h2>
+ <ul>
+ <li>Added <a href="tests/prettify_test.html#PHP">tests</a> for PHP support
+ to address
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=3"
+ >issue 3</a>.
+ <li>Fixed
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=6"
+ >bug</a>: <code>prettyPrintOne</code> was not halting. This was not
+ reachable through the normal entry point.
+ <li>Fixed
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=4"
+ >bug</a>: recursing into a script block or PHP tag that was not properly
+ closed would not silently drop the content.
+ (<a href="tests/prettify_test.html#issue4">test</a>)
+ <li>Fixed
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=8"
+ >bug</a>: was eating tabs
+ (<a href="tests/prettify_test.html#issue8">test</a>)
+ <li>Fixed entity handling so that the caveat
+ <blockquote>
+ <p>Caveats: please properly escape less-thans. <tt>x&amp;lt;y</tt>
+ instead of <tt>x&lt;y</tt>, and use <tt>&quot;</tt> instead of
+ <tt>&amp;quot;</tt> for string delimiters.</p>
+ </blockquote>
+ is no longer applicable.
+ <li>Added noisefree's C#
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=4"
+ >patch</a>
+ <li>Added a <a href="http://google-code-prettify.googlecode.com/files/prettify-small.zip">distribution</a> that has comments and
+ whitespace removed to reduce download size from 45.5kB to 12.8kB.
+ </ul>
+ <h2>4 Jul 2008</h2>
+ <ul>
+ <li>Added <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=17">language specific formatters</a> that are triggered by the presence
+ of a <code>lang-&lt;language-file-extension&gt;</code></li>
+ <li>Fixed <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=29">bug</a>: python handling of <code>'''string'''</code>
+ <li>Fixed bug: <code>/</code> in regex <code>[charsets] should not end regex</code>
+ </ul>
+ <h2>5 Jul 2008</h2>
+ <ul>
+ <li>Defined language extensions for Lisp and Lua</code>
+ </ul>
+ <h2>14 Jul 2008</h2>
+ <ul>
+ <li>Language handlers for F#, OCAML, SQL</code>
+ <li>Support for <code>nocode</code> spans to allow embedding of line
+ numbers and code annotations which should not be styled or otherwise
+ affect the tokenization of prettified code.
+ See the issue 22
+ <a href="tests/prettify_test.html#issue22">testcase</a>.</code>
+ </ul>
+ <h2>6 Jan 2009</h2>
+ <ul>
+ <li>Language handlers for Visual Basic, Haskell, CSS, and WikiText</li>
+ <li>Added <tt>.mxml</tt> extension to the markup style handler for
+ Flex <a href="http://en.wikipedia.org/wiki/MXML">MXML files</a>. See
+ <a
+ href="http://code.google.com/p/google-code-prettify/issues/detail?id=37"
+ >issue 37</a>.
+ <li>Added <tt>.m</tt> extension to the C style handler so that Objective
+ C source files properly highlight. See
+ <a
+ href="http://code.google.com/p/google-code-prettify/issues/detail?id=58"
+ >issue 58</a>.
+ <li>Changed HTML lexer to use the same embedded source mechanism as the
+ wiki language handler, and changed to use the registered
+ CSS handler for STYLE element content.
+ </ul>
+ <h2>21 May 2009</h2>
+ <ul>
+ <li>Rewrote to improve performance on large files.
+ See <a href="http://mikesamuel.blogspot.com/2009/05/efficient-parsing-in-javascript.html">benchmarks</a>.</li>
+ <li>Fixed bugs with highlighting of Haskell line comments, Lisp
+ number literals, Lua strings, C preprocessor directives,
+ newlines in Wiki code on Windows, and newlines in IE6.</li>
+ </ul>
+ <h2>14 August 2009</h2>
+ <ul>
+ <li>Fixed prettifying of <code>&lt;code&gt;</code> blocks with embedded newlines.
+ </ul>
+ <h2>3 October 2009</h2>
+ <ul>
+ <li>Fixed prettifying of XML/HTML tags that contain uppercase letters.
+ </ul>
+ <h2>19 July 2010</h2>
+ <ul>
+ <li>Added support for line numbers. Bug
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=22"
+ >22</a></li>
+ <li>Added YAML support. Bug
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=123"
+ >123</a></li>
+ <li>Added VHDL support courtesy Le Poussin.</li>
+ <li>IE performance improvements. Bug
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=102"
+ >102</a> courtesy jacobly.</li>
+ <li>A variety of markup formatting fixes courtesy smain and thezbyg.</li>
+ <li>Fixed copy and paste in IE[678].
+ <li>Changed output to use <code>&amp;#160;</code> instead of
+ <code>&amp;nbsp;</code> so that the output works when embedded in XML.
+ Bug
+ <a href="http://code.google.com/p/google-code-prettify/issues/detail?id=108"
+ >108</a>.</li>
+ </ul>
+ <h2>7 September 2010</h2>
+ <ul>
+ <li>Added support for coffeescript courtesy Cezary Bartoszuk.</li>
+ </ul>
+ <h2>4 March 2011</h2>
+ <ul>
+ <li>Added a <a href="http://google-code-prettify.googlecode.com/svn/trunk/styles/index.html">themes
+ gallery</a> to showcase contributed styles.</li>
+ <li>Added support for XQuery courtesy Patrick Wied, Nemerle
+ courtesy Zimin A.V., and Latex support courtesy Martin S.</li>
+ </ul>
+ <h2>29 March 2011</h2>
+ <ul>
+ <li>Fixed IE newline issues, and copying/pasting of prettified
+ source code from IE. This required significant internal changes
+ but involves no API changes.
+ <b>Caveat:</b> <code>prettyPrintOne</code> injects the HTML
+ passed to it into a <code>&lt;pre&gt;</code> element.
+ If the HTML comes from a trusted source, this may allow XSS.
+ Do not do this. This should not be a problem for existing apps
+ since the standard usage is to rewrite the HTML and then inject
+ it, so anyone doing that with untrusted HTML already has an XSS
+ vulnerability. If you sanitize and prettify HTML from an
+ untrusted source, sanitize first.

+ <h2>FAQ</h2>
+ <h3 id="langs">For which languages does it work?</h3>
+ <p>The comments in <tt>prettify.js</tt> are authoritative but 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, VB, and Awk and a decent subset of Perl
+ and Ruby, but, because of commenting conventions, doesn't work on
+ Smalltalk, or CAML-like languages.</p>
+
+ <p>LISPy languages are supported via an extension:
+ <a href="http://code.google.com/p/google-code-prettify/source/browse/trunk/src/lang-lisp.js"
+ ><code>lang-lisp.js</code></a>.</p>
+ <p>And similarly for

+
+ <p>If you'd like to add an extension for your favorite language, please
+ look at <tt>src/lang-lisp.js</tt> and file an
+ <a href="http://code.google.com/p/google-code-prettify/issues/list"
+ >issue</a> including your language extension, and a testcase.</p>
+
+ <h3>How do I specify the language of my code?</h3>
+ <p>You don't need to specify the language since <code>prettyprint()</code>
+ will guess. You can specify a language by specifying the language extension
+ along with the <code>prettyprint</code> class like so:</p>
+ <pre class="prettyprint lang-html"
+>&lt;pre class=&quot;prettyprint <b>lang-html</b>&quot;&gt;
+ The lang-* class specifies the language file extensions.
+ File extensions supported by default include
+ "bsh", "c", "cc", "cpp", "cs", "csh", "cyc", "cv", "htm", "html",
+ "java", "js", "m", "mxml", "perl", "pl", "pm", "py", "rb", "sh",
+ "xhtml", "xml", "xsl".
+&lt;/pre&gt;</pre>
+
+ <p>You may also use the
+ <a href="http://dev.w3.org/html5/spec-author-view/the-code-element.html#the-code-element"
+ >HTML 5</a> convention of embedding a <tt>code</tt> element inside the
+ <code>PRE</code> and using <code>language-java</code> style classes.
+ E.g. <xmp class="prettyprint"><pre class="prettyprint"><code class="language-java">...</code></pre></xmp>
+
+ <h3>It doesn't work on <tt>&lt;obfuscated code sample&gt;</tt>?</h3>
+ <p>Yes. Prettifying obfuscated code is like putting lipstick on a pig
+ &mdash; i.e. outside the scope of this tool.</p>
+
+ <h3>Which browsers does it work with?</h3>
+ <p>It's been tested with IE 6, Firefox 1.5 &amp; 2, and Safari 2.0.4.
+ Look at <a href="tests/prettify_test.html">the test page</a> to see if it
+ works in your browser.</p>
+
+ <h3>What's changed?</h3>
+ <p>See the <a href="CHANGES.html">change log</a></p>
+
+ <h3>Why doesn't Prettyprinting of strings work on WordPress?</h3>
+ <p>Apparently wordpress does "smart quoting" which changes close quotes.
+ This causes end quotes to not match up with open quotes.
+ <p>This breaks prettifying as well as copying and pasting of code samples.
+ See
+ <a href="http://wordpress.org/support/topic/125038"
+ >WordPress's help center</a> for info on how to stop smart quoting of code
+ snippets.</p>
+
+ <h3 id="linenums">How do I put line numbers in my code?</h3>
+ <p>You can use the <code>linenums</code> class to turn on line
+ numbering. If your code doesn't start at line number 1, you can
+ add a colon and a line number to the end of that class as in
+ <code>linenums:52</code>.
+
+ <p>For example
+<pre class="prettyprint">&lt;pre class="prettyprint linenums:<b>4</b>"
+&gt;// This is line 4.
+foo();
+bar();
+baz();
+boo();
+far();
+faz();
+&lt;pre&gt;</pre>
+ produces
+<pre class="prettyprint linenums:4"
+>// This is line 4.
+foo();
+bar();
+baz();
+boo();
+far();
+faz();
+</pre>
+
+ <h3>How do I prevent a portion of markup from being marked as code?</h3>
+ <p>You can use the <code>nocode</code> class to identify a span of markup
+ that is not code.
+<pre class="prettyprint">&lt;pre class=prettyprint&gt;
+int x = foo(); /* This is a comment &lt;span class="nocode"&gt;This is not code&lt;/span&gt;
+ Continuation of comment */
+int y = bar();
+&lt;/pre&gt;</pre>
+produces
+<pre class="prettyprint">
+int x = foo(); /* This is a comment <span class="nocode">This is not code</span>
+ Continuation of comment */
+int y = bar();
+</pre>
+
+ <p>For a more complete example see the issue22
+ <a href="tests/prettify_test.html#issue22">testcase</a>.</p>
+
+ <h3>I get an error message "a is not a function" or "opt_whenDone is not a function"</h3>
+ <p>If you are calling <code>prettyPrint</code> via an event handler, wrap it in a function.
+ Instead of doing
+ <blockquote>
+ <code class="prettyprint lang-js"
+ >addEventListener('load', prettyPrint, false);</code>
+ </blockquote>
+ wrap it in a closure like
+ <blockquote>
+ <code class="prettyprint lang-js"
+ >addEventListener('load', function (event) { prettyPrint() }, false);</code>
+ </blockquote>
+ so that the browser does not pass an event object to <code>prettyPrint</code> which
+ will confuse it.
+
+ <h3>How can I customize the colors and styles of my code?</h3>
+ <p>
+ Prettify adds <code>&lt;span&gt;</code> with <code>class</code>es describing
+ the kind of code. You can create CSS styles to matches these
+ classes.
+ See the
+ <a href="http://google-code-prettify.googlecode.com/svn/trunk/styles/index.html">
+ theme gallery</a> for examples.

+/**
+ * @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>
+ * @requires console
+ */
+
+// JSLint declarations
+/*global console, document, navigator, setTimeout, window */
+
+/**
+ * Split {@code prettyPrint} into multiple timeouts so as not to interfere with
+ * UI events.
+ * If set to {@code false}, {@code prettyPrint()} is synchronous.
