WP-Syntax provides clean syntax highlighting using
GeSHi — supporting a wide range of popular
languages. It supports highlighting with or without line numbers and maintains formatting while copying snippets of code
from the browser.
Using it can be as simple as selecting an editor style or adding shortcode around your scripts which you want to highlight and Enlighter takes care of the rest. An easy to use Theme-Customizer is included to modify the build-in themes without any css knowlegde!
It also supports the automatic creation of tab-panes to display code-groups together (useful for multi-language examples – e.g. html+css+js)
