Out of the box, <a href="https://wordpress.org/extend/plugins/wp-syntax/" rel="ugc">WP-Syntax</a> 
colors code using the default <a href="http://qbnz.com/highlighter/" rel="nofollow ugc">GeSHi</a> colors. 
Per the authors advice in the ‘Advanced Customization’ section of 
<a href="https://wordpress.org/extend/plugins/wp-syntax/other_notes/" rel="ugc">Other Notes</a>, 
you can configure GeSHi yourself by handling the <code>wp_syntax_init_geshi</code> 
hook and configuring it programmatically.
Since I wanted to do just that, I decided to publish a generic plugin 
for folks who wanted to configure GeSHi following this approach.
<h3>Release Notes</h3>
1.2 : Set keyword expansion in the plugin file. Uses Wp-Syntax 0.9, which depends on GeSHi 1.0.7.22.
1.1 : Fixed grammatical errors in the readme.txt. Uses Wp-Syntax 0.9, which depends on GeSHi 1.0.7.22.

SyntaxHighlighter Evolved

Just what I was looking for.
Thank you guys.

Perfect

I'm a longtime user of syntaxhighlighter evolved, so thanks for the excellent plugin!

The only downside I've recently experienced is the lack of bbPress integration, hence 4 stars rather than 5. If you need this for non-bbPress projects, this is a great choice.

longtime fan, but no bbpress support


It works and show code beautifully on pages, But if you copied that code and want to use it, the it shows errors, Looks like it add some spaces,



I tried it with php shorcode, and when i copied the code from the frontend of the page, It gives Parse error: syntax error, unexpected...


Works, But if you copy code and wan to to use it show error
