SimpleCode for WordPress is a horribly simple plugin for WordPress. It has been successfully tested on versions 1.5.3 and 2.0.2
The plugin takes ordinary markup, and processes it for use within code examples.
SimpleCode for WordPress was inspired by Dan Cederholm’s Simplecode script available on simplebits.com
I got tired of having to go to an external page, and decided it would be nicer to have something similar one click away, so I put this together.
