Texy*Handlers na oficiálnom webe

Zdravím.

Za môjho pohľadu patria Handlers medzi najzaujímavejšie veci na Texy. Čím sa Texy oveľa viac vzďaľuje od písacích nástrojov typu WYSIWYG a dáva článku nielen validný, sémantický, ale aj multimediálny obsah.

Chcel by so sa opýtať či bo bolo možné pre Handlers zriadiť nejakú špeciálnu sekciu na webovej stránke texy.info, kde by sa zhromažďovali a pribúdali by nové.

Vycucnuté z Texy, ktoré každý pozná:

Flash Handler

/**

{
    $texy = $invocation->getTexy();

    if (substr($image->URL, -4) === '.swf')  // accepts only *.swf
    {
        $movie = Texy::prependRoot($image->URL, $texy->imageModule->root);

        $dimensions =
               ($image->width ? 'width="'.$image->width.'" ' : '')
            . ($image->height ? 'width="'.$image->height.'" ' : '');

        $movie = htmlSpecialChars($movie);
        $altContent = htmlSpecialChars($image->modifier->title);

FSHL Handler

    $elCode = $elPre->create('code', $content);

    return $elPre;
}
