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.

WordPress Rainbow Hilite

As developer I need to post code snippets from time to time and this plugin helps me to highlight the code nicely. Without a large overhead this plugin only enqueues style and js, which is nice to reduce the load.
Thx :)
