Web pages contain many snippets from different languages, like HTML, PHP, CSS, and JavaScript. Chili 1.x cannot highlight mixed language source code automatically, but the forthcoming released Chili 2.0 will be is able to do that.
Meanwhile, if you are using a Chili + Enzymes setup, then it’s possible to write an Enzymes template capable of making Chili 1.x highlight a web page perfectly (expanding on my previous php template).
Here is the new updated (2007/02/19) chili-web.php Enzymes template. At the moment it supports XHTML, and embedded CSS, JavaScript, and PHP snippets.
<?php

The WordPress file /wp-content /themes /default /comments-popup.php is a page that uses all the supported languages, so it’s a good test for the previous template:
<?php
/* Don't remove these lines. */
add_filter('comment_text', 'popuplinks');
while ( have_posts()) : the_post();
?>

Chili & Enzymes confirm to be a perfect match.
