WordPress Plugin of the week this week is Code Prettify by Kaspars.
What is it?
It uses the Google Code Prettify library and applies code highlighting automatically to all <pre> and <code> tags on the page or post.
Why do you need it?
This is a particularly helpful plugin if you want a nice and easy way to display code markup without having to format everything.
For example, you can see how pretty code looks like in this post.
How much does it cost?
Code Prettify by Kaspars is completely free.
