I tried to find syntaxhighlighter for WordPress a lot of times. All my attempts didn’t give me a simple result.
For many plugins user has to use special syntax like [css]…[/css] or [php]…[/php]. Sometime syntaxhighlighter works only with classes of syntax like <… class=”css”>. So plugins like Syntax Highlighter MT, WP Code Highlight, CodeColorer don’t work well.
Code Prettify is not alternative to standard <pre> tag. It’s just nice bonus.
