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;

}

add_filter('bb_allowed_tags', 'allow_syntax_tag');



include_once("geshi/geshi.php");



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";

}



function wp_syntax_code_trim($code)

{

// special ltrim b/c leading whitespace matters on 1st line of content

$code = preg_replace("/^s*n/siU", "", $code);

$code = rtrim($code);

return $code;

}



function wp_syntax_substitute(&$match)

{

global $wp_syntax_token, $wp_syntax_matches;



$i = count($wp_syntax_matches);

$wp_syntax_matches[$i] = $match;



return "nn<p>" . $wp_syntax_token . sprintf("%03d", $i) . "</p>nn";

}



function wp_syntax_line_numbers($code, $start)

{

$line_count = count(explode("n", $code));

$output = "<pre>";

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

{

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

}

$output .= "</pre>";

return $output;

}



function wp_syntax_highlight($match)

{

global $wp_syntax_matches;



$i = intval($match[1]);

$match = $wp_syntax_matches[$i];



$language = strtolower(trim($match[1]));

$line = trim($match[2]);

$escaped = trim($match[3]);

$code = wp_syntax_code_trim($match[4]);

if ($escaped == "true") $code = htmlspecialchars_decode($code);

//$code = clean_pre($code);// new

$geshi = new GeSHi($code, $language);

$geshi->enable_keyword_links(false);

do_action_ref_array('wp_syntax_init_geshi', array(&$geshi));

}

else

{

$output .= "<div class="code">";

$output .= $geshi->parse_code();

$output .= "</div>";

}



$output .= "</div>n";



return $output;
