SyntaxHighlighter Plus Plugin

SyntaxHighlighter Plus is a WordPress plugin for code syntax highlighting. It is an enhanced version of the original SyntaxHighlighter by Matt, Viper007Bond and mdawaffe. Please give them a big applause for making such a great plugin!

SyntaxHighlighter allows you to easily post syntax highlighted code all without loosing it’s formatting or making an manual changes.

It supports the following languages (the alias for use in the post is listed next to the name):

• Bash — bash, sh
• C++ — cpp, c, c++
• C# — c#, c-sharp, csharp
• CSS — css
• Delphi — delphi, pascal
• Diff — diff
• Groovy — groovy
• Java — java
• JavaScript — js, jscript, javascript
• Perl — perl, pl
• PHP — php
• Plain text — plain, text
• Python — py, python
• Ruby — rb, ruby, rails, ror
• Scala — scala
• SQL — sql
• VB — vb, vb.net
• XML/HTML — xml, html, xhtml, xslt

This plugin uses the SyntaxHighlighter JavaScript package by Alex Gorbatchev.

Other BBCode Methods

Find [sourcecode language='css']code here[/sourcecode] too long to type? Here’s some alternative examples:

• [source language='css']code here[/source]
• [code language='css']code here[/code]
• [sourcecode lang='css']code here[/sourcecode]
• [source lang='css']code here[/source]
• [code lang='css']code here[/code]
• [sourcecode='css']code here[/sourcecode]
• [source='css']code here[/source]
• [code='css']code here[/code]
• [lang='css']code here[/lang]
• [css]code here[/css] (or any of the supported language)

Note: Quotation marks around the language can be omitted for even shorter and neater syntax. 🙂

Updgrading From A Previous Version

To upgrade from a previous version of this plugin, delete the entire folder and files from the previous version of the plugin and then follow the installation instructions below.

• Starting from WordPress 2.7, plugin upgrades are handled by WordPress, there is no need to manually upload files.

Important: If you have made any changes to the CSS file, please make sure to back it up before upgrade!

Uploading The Plugin

Extract all files from the ZIP file, making sure to keep the file structure intact, and then upload it to /wp-content/plugins/.

This should result in the following file structure:

- wp-content - plugins - syntaxhighlighter-plus | readme.txt | syntaxhighlighter.php - syntaxhighlighter - scripts | clipboard.swf | shBrushBash.js | shBrushCpp.js | shBrushCSharp.js | [...] | shCore.js | shLegacy.js - src | shCore.js | shLegacy.js - styles | SyntaxHighlighter.css

Plugin Activation

Go to the admin area of your WordPress install and click on the “Plugins” menu. Click on “Activate” for the “SyntaxHighlighter” plugin.

Plugin Usage

Just wrap your code in [sourcecode language='css']code here[/sourcecode]. The language attribute is required! See the plugin’s description for a list of valid language attributes.

The BBCode in my post is being replaced with <pre>’s just fine, but I don’t see the syntax highlighting!

Make sure your theme’s footer has <?php wp_footer(); ?> somewhere in it, otherwise the JavaScript highlighting files won’t be loaded.

I still see the BBCode in my post. What gives?

Make sure you correctly use the BBCode with a valid language attribute. A malformed usage of it won’t result in replacement.

I use the visual editor, my code has lots of line breaks inserted, what do I do?

Use ‘shift + return’ instead of ‘return’ when changing lines.
