If you're looking for the SuperACL plugin for pre-2008-05-05 DokuWiki, please scroll down.

This plugin is based on acl, but allows to filter the bottom table of ACLs, so that you don't loose the overview over all the rules applying to your currently selected page/namespace.

Download the plugin here (manually or via Plugin Manager): http://pb.wh4f.de/dokuwiki/superacl2.zip Use this download only for DokuWiki 2008-05-05!

The following only corresponds to the SuperACL-version for DokuWiki releases 2006-11-06 and 2007-06-26

This plugin is based on acl, but allows to select the namespace where you want to edit access rights, in opposite to the original plugin which requires you to browse a page in the corresponding namespace. This results in better overview about the global ACL situation in the wiki.

Since in big wikis it takes some time to display all namespaces and all the pages of the selected namespace, the new version of SuperACL offers the configuration option to enable “Use AJAX”. This will speedup all roundtrip processes (e.g. set an ACL) by deferring the population of the dropdown-selectors.

Download the plugin here (manually or via Plugin Manager): http://pb.wh4f.de/dokuwiki/superacl.zip Use this download only for DokuWiki 2006-11-06 or 2007-06-26!
Old version (without AJAX support): http://pb.wh4f.de/dokuwiki/superacl-2007-08-16.zip

• description : if you try to get ACL for “*” (the first namespace in the list) you get at least 2 warnings “warning: Compilation failed: nothing to repeat at offset 1” for preg_grep on line 183.
• solution I've put the following code just before line 183 :

$id = str_replace('*', '\\*', $id);
$id = str_replace('+', '\\+', $id);

It seems it works…

Thank you for the hint, I included it with the new version 2007-08-13.
