I worked on the wp-syntax plugin but it doesn’t parse the code

do you have an idea what’s missing?

function allow_syntax_tag($tags) {

$tags['pre'] = array('lang' => array(), 'line' => array(), 'escaped' => array(), 'style' => array(), 'width' => array());

return $tags;

}

if (!defined("BB_PLUGIN_URL"))  define("BB_PLUGIN_URL",  bb_get_uri() . "/my-plugins");



function wp_syntax_head()

{

$css_url = BB_PLUGIN_URL . "wp-syntax/wp-syntax.css";

echo "n".'<link rel="stylesheet" href="' . $css_url . '" type="text/css" media="screen" />'."n";

}

return $code;

for ($i = 0; $i < $line_count; $i++)

{

$output .= ($start + $i) . "n";
