[dokuwiki] alternative for js_compress()

Hi,

i just played a bit with some php-regex functions to compact .js files.
I think it might be a better solution for dokuwiki's js_compress() 
(inc/js.php) too.

I tried some js files with that script:
<?php
$content=file_get_contents($_SERVER['QUERY_STRING']);

$prot_search=$prot_replace=array();

//protect strings and keywords
$content=preg_replace_callback(array('|\\"|','|\\\'|','|\".+\"|','|\'.
+\'|'),'cut_unparsed',$content);

//strip comments
$content=preg_replace(array('|/\*.*\*/|ms','|//.*$|m'),'',$content);

//protect regex
$content=preg_replace_callback('|/.+/|','cut_unparsed',$content);

//strip spaces
$content=preg_replace(array('|^\s*|m','|(\w\s+[\$\w\'%])?\s*|','|;
(\})|'),'${1}',$content);

$content=str_replace($prot_search,$prot_replace,$content);
echo $content;


function cut_unparsed($matches) {
        global $prot_replace,$prot_search;
        $prot_replace[]=$matches[0];
        return ($prot_search[]='~'.count($prot_replace).'~');
}

?>


I'll keep the code at 
http://wiki.erazor-zone.de/wiki:projects:php:js_compress .

Cheers Alex
