From: Antonio Ospite Date: Fri, 9 Dec 2011 23:49:56 +0000 (+0100) Subject: Add the Direct Download link to the page on a UrlFetched event X-Git-Tag: 0.3~9 X-Git-Url: https://git.ao2.it/GM_direct_download_links.git/commitdiff_plain/15eb7fbb4da6258e7fbbc499d342b68463bc132a?ds=inline;hp=1b53269ee66fbdba093c562eec82f976d3c0f632 Add the Direct Download link to the page on a UrlFetched event Calling _add_link() asynchronously will make it easy to add some URL processing mechanism between _get_URL() and _add_link() in case the URL we get needs to be processed somehow before being added to the page as a Direct Download Link.
