NewsList

Questions answered by this recipe

How can I insert a list of recently changed/updated wikipages in a short form that can be used in the sidebar, for example?

Answer

Include this in your php files:

 Markup('news','fulltext','/\(:news\s*(.*?):\\)/e',"newsList('$1')");
function newsList ($arg) {
	global $WorkDir;
	$args = explode(" ",$arg);
	$reg = array();
	$max = 500;
	$exclude = false;
	$grps=array();
	foreach ($args as $i=>$val) {
		if (preg_match("/(\d+)/",$val,$max)) {
			$max = $max[1];
			continue;
		}
		if ($val=='not') {
			$exclude = true;
		}
		$grps[$val] = true;
	}
	$reg = "/^(.+?)\.[^,]+$/";

	$dir = opendir($WorkDir);
	$out = array();
	$files = array();
	while ($file = readdir ($dir)) {
		if (!preg_match($reg,$file,$grp)||preg_match("/.(All)*RecentChanges/",$file)) continue;
		$grp = $grp[1];
		if ($grps[$grp] xor $exclude)
			$files[filemtime("$WorkDir/$file")] = $file;
	}
	krsort($files);
	foreach($files as $i => $val) 
		if ($max--<=0) break; 
		else $out[]="*[[".str_replace(".","/",$val)."]] [--(".date("d.m.y",$i).")--]";
	closedir($dir);
	return implode("\n",$out);
}

This will create a indexlist sorted by date. It will skip the AllRecentChanges and RecentChanges pages and it only looks into specified groups, so this will need some administration from your side. Since I needed this script for a CMS like website, I didn't want to list the Site etc. groups. You can specify a maximum of listet changes by adding a number. Use it like this:

 (:news Main Cookbook 8:)

This will list the eight most recent changes (depending on the filechange dates in your wiki.d directory) in the Main and Cookbook group. You can also invert the used groups by applying a not to the arguments, i.e.

 (:news not Site:)
