===== Wikka Menulets =====
{{lastedit show="3"}}

In the trac as [[Ticket:28]].
 
As part of my proposal for a general overhaul of the [[WikkaMenus menu management system]] in WikkaWiki, I suggest we replace the current system-generated items that occur in the main menu and footer menu with a series of **menulets**, i.e. mini-actions generating content for menu items.
Any of these mini-actions can of course be used in the page body as well.

Here's a list of potential menulets and their output, that I've uploaded to this server. 
Suggestions/modifications are welcome. 

----
==##""{{acls}}""##== 

Prints a link  to ##""CurrentPage/acls""## if the user has access to the ACLs: {{acls}}

%%(php)
<?php
if ($this->page){
	if ($owner = $this->GetPageOwner()){
		if ($owner == "(Public)"){
			print $this->IsAdmin() ? "<a href=\"".$this->href("acls")."\">(Edit ACLs)</a>\n" : ""; #i18n
		} elseif ($this->UserIsOwner()){
			print "<a href=\"".$this->href("acls")."\">Edit ACLs</a>\n"; #i18n
		} 
	} else {
		print ($this->GetUser()) ? " (<a href=\"".$this->href("claim")."\">Take Ownership</a>)\n" : ""; #i18n
	}
}
?>
%%---
~&My version: %%(php)<?php
// UI defines (i18n)
define('ACLS_OWNER', "Edit ACLs");		# ACLs editable by owner (includes admin)
define('ACLS_ADMIN', "(Edit ACLs)");		# public page - ACLs editable by admin only
define('ACLS_NONE', "(Take Ownership)");	# not-owned pages can be claimed
// generate output (or not)
if ($this->page)
{
	switch (TRUE)
	{
		case ($this->UserIsOwner()):
			echo '<a href="'.$this->Href('acls').'">'.ACLS_OWNER.'</a>'."\n";
			break;
		case ('(Public)' == $this->page['owner']):
			if ($this->IsAdmin()) echo '<a href="'.$this->Href('acls').'">'.ACLS_ADMIN.'</a>'."\n";
			break;
		case ('' == $this->page['owner']):
			if ($this->GetUser()) echo '<a href="'.$this->Href('claim').'">'.ACLS_NONE.'</a>'."\n";
			break;
		default:
			// print nothing
	}
}
?>%% --- A few notes about the differences:
~~-UI strings are grouped together at the top: easier maintainance; comments to give hints to translators;
~~-when $this->page is set, all data of the page is known; no need to use ""GetPageOwner()"" which would do another page load (or at least access the cache again);
~~-using a switch construct gives equal weight to the different cases, and makes it easily extensible for possible other types of ownership (groups? projects? aliens?);
~~-using single quotes wherever possible for speed (but always double quotes for strings to be internationalized);
~~-consistent spelling: the method is called Href() so we don't call it as href().

==##""{{attachments}}""##== 

Prints a link to the FilesHandler differently depending if there are attached documents to the current page or not: {{attachments}}.

%%(php)
<?php
	// this is a menulet action relying on the files handler
	// upload path
	$upload_path = $this->config['upload_path'].'/'.$this->GetPageTag();
	$AttachmentClass = "";
		if(is_dir($upload_path) ){
			$handle = opendir($upload_path);
			while( (gettype( $name = readdir($handle)) != "boolean")){
				$name_array[] = $name;
			}
			foreach($name_array as $temp) $folder_content .= $temp;
			closedir($handle);
			if($folder_content == "...") {
				$AttachmentClass ="emptyfolder"; // the upload path is empty
			} else {
				$AttachmentClass = "fullfolder"; // the upload path contains attachments
			}
		}
		else $AttachmentClass = "inexistingfolder"; // the upload path does not exist
		
	echo  "<a href=\"".$this->href("files")."\" title=\"Click to manage attachments\" class=\"".$AttachmentClass."\">Attachments</a>\n"; #i18n
?>
%%

Add something like this to the .css file:
%%(css)
.fullfolder { 
	font-weight: bold;
	border: 1px solid red;
}
.emptyfolder {
}
.inexistingfolder {

$email = $this->GetConfigValue("admin_email");

// print spam-safe mailto link
$patterns = array("'@'", "'\.'");
$replace = array("[at]", "[dot]"); 
echo "<a href=\"mailto:".preg_replace($patterns, $replace, $email)."\" title=\"Send us your feedback\">Contact</a>"; #i18n

// print plain mailto link

==##""{{randompage}}""##==//like the "Random Article" on wikipedia...//
~ ##""{{randompage}}""##
~~ Prints a link to a random page on this wiki. e.g. [[HomePage RandomPage]]
~ ##""{{randompage title="Random"}}""##
~~ Change the title, use ##""{{randompage title=&#34;&#34;}}""## to display the real pagename.
~ ##""{{randompage pos="ActionInfo, HandlerInfo, FunctionInfo"}}""##
~~ Make a positive list to choose from, don't use all pages. (note the default neg list)
~ ##""{{randompage neg="HomePage, PageIndex"}}""##
~~ Use all pages exept the ones used in this negative list / override the default neg list in $neg_list_default
~ ##""{{randompage title="Random Link" pos="ActionInfo, HandlerInfo, FunctionInfo" neg=&#34;&#34;}}""##
~~ Clear the default negative list, use only pages from the pos list and use "Random Link" as title.
~ ##""{{randompage pos="HomePage|DonateNow|DonateNow|DonateNow"}}""##
~~ You can influence the random ratio... (+other way of defining the list)

==##""{{wordcount}}""##==

Inserts a wordcount (my format, your format, or no format) into a document.  Needed something quick and dirty, so there's some refinement yet to be done.
