// $Log: WantedPages.php,v $
// Revision 1.16 2004/11/23 15:17:19 rurban
// better support for case_exact search (not caseexact for consistency),
// plugin args simplification:
// handle and explode exclude and pages argument in WikiPlugin::getArgs
// and exclude in advance (at the sql level if possible)
// handle sortby and limit from request override in WikiPlugin::getArgs
// ListSubpages: renamed pages to maxpages
//
// Revision 1.15 2004/11/23 13:35:49 rurban
// add case_exact search
//
// Revision 1.14 2004/11/20 17:35:58 rurban
// improved WantedPages SQL backends
// PageList::sortby new 3rd arg valid_fields (override db fields)
// WantedPages sql pager inexact for performance reasons:
// assume 3 wantedfrom per page, to be correct, no getTotal()
// support exclude argument for get_all_pages, new _sql_set()
//
// Revision 1.13 2004/11/20 11:28:49 rurban
// fix a yet unused PageList customPageListColumns bug (merge class not decl to _types)
// change WantedPages to use PageList
// change WantedPages to print the list of referenced pages, not just the count.
// the old version was renamed to WantedPagesOld
// fix and add handling of most standard PageList arguments (limit, exclude, ...)
// TODO: pagename sorting, dumb/WantedPagesIter and SQL optimization
//
// Revision 1.12 2004/10/04 23:39:34 rurban
// just aesthetics
//
// Revision 1.11 2004/04/20 00:56:00 rurban
// more paging support and paging fix for shorter lists
//
// Revision 1.10 2004/04/18 01:44:02 rurban
// more sortby+limit support
//
// Revision 1.9 2004/04/10 04:15:06 rurban
// sf.net 927122 Suggestion
//
// Revision 1.8 2004/02/17 12:11:36 rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
//
// Revision 1.7 2003/12/19 06:57:49 carstenklapp
// Bugfix: Enclose FullTextSearch query with quotes when the [Wiki Word]
// contains spaces.
//
// Revision 1.6 2003/11/19 17:08:23 carstenklapp
// New feature: Clicking on the number of citations in the links column
// now does a FullTextSearch for the WantedPage link!
//
// Revision 1.5 2003/03/25 21:05:27 dairiki
// Ensure pagenames are strings.
//
// Revision 1.4 2003/01/18 22:14:24 carstenklapp
// Code cleanup:
// Reformatting & tabs to spaces;
// Added copyleft, getVersion, getDescription, rcs_id.
