How to use SyntaxHighlighter.

Placing the code

Place your code on the page and surround it with <pre> tag. Set name attribute to code and class attribute to one of the language aliases you wish to use.

<pre name="code" class="c-sharp">
... some code here ...
</pre>

NOTE: One important thing to watch out for is opening triangular bracket <. It must be replaced with an HTML equivalent of &lt; in all cases. Failure to do won’t break the page, but might break the source code displayed.

An alternative to <pre> is to use <textarea> tag. There are no problems with < character in that case. The main problem is that it doesn’t look as good as <pre> tag if for some reason JavaScript didn’t work (in RSS feed for example).

<textarea name="code" class="c#" cols="60" rows="10">
... some code here ...
</textarea>

Extended configuration

There’s a way to pass a few configuration options to the code block. It’s done via colon separated arguments.

<pre name="code" class="html:collapse">
... some code here ...
</pre>

Making it work

Finally, to get the whole thing to render properly on the page, you have to add JavaScript to the page.

<link type="text/css" rel="stylesheet" href="css/SyntaxHighlighter.css"></link>
<script language="javascript" src="js/shCore.js"></script>
<script language="javascript" src="js/shBrushCSharp.js"></script>
<script language="javascript" src="js/shBrushXml.js"></script>
<script language="javascript">
dp.SyntaxHighlighter.ClipboardSwf = '/flash/clipboard.swf';
dp.SyntaxHighlighter.HighlightAll('code');
</script>

For optimal result, place this code at the very end of your page. Check HighlightAll for more details about the function.

Here’s a list of supported languages and their aliases:

Language Aliases
C++ cpp, c, c++
C# c#, c-sharp, csharp
CSS css
Delphi delphi, pascal
Java java
Java Script js, jscript, javascript
PHP php
Python py, python
Ruby rb, ruby, rails, ror
Sql sql
VB vb, vb.net
XML/HTML xml, html, xhtml,

These options allow you to individually configure text blocks.

nogutter Will display no gutter.
nocontrols Will display no controls at the top.
collapse Will collapse the block by default.
firstline[value] Will begin line count at value. Default value is 1.
showcolumns Will show row columns in the first line.

The options are passed together with the alias and are separated by a colon : character.

<pre name="code" class="html:nocontrols:firstline[10]">
... some code here ...
</pre>
