<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, Makefiles,
and Rust.
It works passably on Ruby, PHP, VB, and Awk and a decent subset of Perl
and Ruby, but, because of commenting conventions, but doesn't work on
Smalltalk.</p>
<p>Other languages are supported via extensions:

<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"
><pre class="prettyprint <b>lang-html</b>">
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".
</pre></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><obfuscated code sample></tt>?</h3>
<p>Yes. Prettifying obfuscated code is like putting lipstick on a pig
— 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 & 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"><pre class="prettyprint linenums:<b>4</b>"
>// This is line 4.
foo();
bar();
baz();
boo();
far();
faz();
<pre></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"><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></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><span></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.
</p>
<h3>I can't add classes to my code (because it comes from Markdown, etc.)</h3>
<p>
Instead of <code class="prettyprint"><pre class="prettyprint ..."></code> you can use a
comment or processing instructions that survives processing instructions :
<code><?prettify ...?></code> works as explained in
<a href="http://code.google.com/p/google-code-prettify/wiki/GettingStarted">Getting Started</a></p>
