在wordpress博客中自动突出显示代码

Question

I've a self installed wordpres blog full of Python snippets and I'd like to have them highlighted (source code colored). I tried to install a couple of plugins like wp-syntax and Jquery.Syntax but they require me to edit all my posts adding some attrs to the pre tags.

How can I hack into the plugins or wordpress in other to apply the plugins to all the pre tags?

Answer 1

You can create a simple plugin that will register a "filter". This filter will apply to all your posts :

function enhance_pre_tag_filter($content){
    $content = preg_replace( '/<pre>/', '<pre python_tags>', $content );
    return $content;
}

foreach(array('the_content','the_title','comment_text') as $filter)
    add_filter($filter, 'enhance_pre_tag_filter',9);
