It’s really great when you discover that people have already done exactly the thing you wanted to do. I went from thinking I needed to write my own code highlighting plugin for WordPress to not only finding out that someone has already written one, but that it is also built on a generic code hightlighting engine that is easy to add new languages to. Then I figured I’d need to add Processing as a language to GeSHi, or at least add to the Java file. But someone already did that, too! So now I have lovely, simple code highlighting that is the same as the code highlighting in the PDE.
