37 * This is a list of calendar appointments.
38 * Same arguments as Calendar, so no one is confused
39 * Uses <dl><dd>DATE<dt>page contents...
40 * Derived from Calendar.php by Martin Norbäck <martin@safelogic.se>
42 * Insert this plugin into your Calendar page, for example in WikiUser/Calendar:
43 * <?plugin Calendar ?>
44 * <?plugin CalendarList ?>
46 * Honors now year + month args as start base - together with Calendar navigation.
47 * The behaviour before 2007 with last/next_n_days was to start now.

231 // CalendarList pages now in parallel with Calendar: year + month args as start base, The behaviour before 2007 with last/next_n_days was to start now.
233 // Revision 1.9 2006/05/14 17:40:31 rurban
234 // Patch #1232730 by banjo
236 // Revision 1.8 2005/10/12 06:18:31 rurban
237 // dont overdo constants
239 // Revision 1.7 2005/07/21 18:55:55 rurban
240 // applied mpullen patch (Revised to work on all date range combinations...),
241 // but still does not work as documented.
243 // Revision 1.6.2 2005/06/24 12:00:00 mpullen
244 // Corrected bug in the main WHILE loop to detect proper termination point in time
245 // {it was stopping one day too soon in either direction}.
247 // Revision 1.6.1 2005/06/23 12:00:00 mpullen
248 // Revised to work on all date range combinations (past and future, by days or count of events)
249 // Externalized five control parameter constants to the config.ini file (new section 8 for PLUGINs)
251 // Revision 1.6 2005/04/02 03:05:44 uckelman
252 // Removed & from vars passed by reference (not needed, causes PHP to complain).
254 // Revision 1.5 2004/12/06 19:15:04 rurban
255 // save edit-time links as requested in #946679
257 // Revision 1.4 2004/12/06 18:32:39 rurban

260 // Revision 1.3 2004/09/22 13:36:45 rurban
261 // Support ranges, based on a simple patch by JoshWand
262 // next_n_days, last_n_days, next_n
265 // Revision 1.2 2004/02/17 12:11:36 rurban
266 // added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far,
267 // because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed.
268 // (InterWikiSearch, IncludeSiteMap, ...)
270 // Revision 1.1 2003/11/18 19:06:03 carstenklapp
271 // New plugin to be used in conjunction with the Calendar plugin.
