+Autoloader
+==========
+
+* [Home](help)
+
+There is some initial support to class autoloading in Friendica core.
+
+The autoloader code is in `include/autoloader.php`.
+It's derived from composer autoloader code.
+
+Namespaces and Classes are mapped to folders and files in `library/`,
+and the map must be updated by hand, because we don't use composer yet.
+The mapping is defined by files in `include/autoloader/` folder.
+
+Currently, only HTMLPurifier library is loaded using autoloader.
+
+
+## A quick introdution to class autoloading
+
+The autoloader it's a way for php to automagically include the file that define a class when the class is first used, without the need to use "require_once" every time.
+
+Once is setup you don't have to use it in any way. You need a class? you use the class.
+
+At his basic is a function passed to the "spl_autoload_register()" function, which receive as argument the class name the script want and is it job to include the correct php file where that class is defined.
+The best source for documentation is [php site](http://php.net/manual/en/language.oop5.autoload.php).
+
+One example, based on fictional friendica code.
+
+Let's say you have a php file in "include/" that define a very useful class:
+
+```
+    file: include/ItemsManager.php
+    <?php
+    namespace \Friendica;
+    
+    class ItemsManager {
+       public function getAll() { ... }
+       public function getByID($id) { ... }
+    }
+```
+
+The class "ItemsManager" has been declared in "Friendica" namespace.
+Namespaces are useful to keep things separated and avoid names clash (could be that a library you want to use defines a class named "ItemsManager", but as long as is in another namespace, you don't have any problem)
+
+If we were using composer, we had configured it with path where to find the classes of "Friendica" namespace, and then the composer script will generate the autoloader machinery for us.
+As we don't use composer, we need check that the autoloader knows the Friendica namespace.
+So in "include/autoloader/autoload_psr4.php" there should be something like
+
+```
+    $vendorDir = dirname(dirname(dirname(__FILE__)))."/library";
+    $baseDir = dirname($vendorDir);
+    return array(
+       "Friendica" => array($baseDir."/include");
+    );
+```
+
+
+That tells the autoloader code to look for files that defines classes in "Friendica" namespace under "include/" folder. (And btw, that's why the file has the same name as the class it defines.)
+
+*note*: The structure of files in "include/autoloader/" has been copied from the code generated by composer, to ease the work of enable autoloader for external libraries under "library/"
+
+Let's say now that you need to load some items in a view, maybe in a fictional "mod/network.php".
+Somewere at the start of the scripts, the autoloader was initialized. In Friendica is done at the top of "boot.php", with "require_once('include/autoloader.php');".
+
+The code will be something like:
+
+```
+    file: mod/network.php
+    <?php
+    
+    function network_content(&$a) {
+       $itemsmanager = new \Friendica\ItemsManager();
+       $items = $itemsmanager->getAll();
+    
+       // pass $items to template
+       // return result
+    }
+```
+
+That's a quite simple example, but look: no "require()"!
+You need to use a class, you use the class and you don't need to do anything more.
+
+Going further: now we have a bunch of "*Manager" classes that cause some code duplication, let's define a BaseManager class, where to move all code in common between all managers:
+
+```
+    file: include/BaseManager.php
+    <?php
+    namespace \Friendica;
+    
+    class BaseManager {
+      public function thatFunctionEveryManagerUses() { ... }
+    }
+```
+
+and then let's change the ItemsManager class to use this code
+
+```
+    file: include/ItemsManager.php
+    <?php
+    namespace \Friendica;
+    
+    class ItemsManager extends BaseManager {
+       public function getAll() { ... }
+       public function getByID($id) { ... }
+    }
+```
+
+The autoloader don't mind what you need the class for. You need a class, you get the class.
+It works with the "BaseManager" example here, it works when we need to call static methods on a class:
+
+```
+    file: include/dfrn.php
+    <?php    
+    namespace \Friendica;
+    
+    class dfrn {
+      public static function  mail($item, $owner) { ... }
+    }
+```
+
+```
+    file: mod/mail.php
+    <?php
+    
+    mail_post($a){
+     ...
+     \Friendica\dfrn::mail($item, $owner);
+     ...
+    }
+```
+
+If your code is in same namespace as the class you need, you don't need to prepend it:
+
+```
+    file: include/delivery.php
+    <?php
+    
+    namespace \Friendica;
+    
+    // this is the same content of current include/delivery.php, 
+    // but has been declared to be in "Friendica" namespace
+    
+    [...]
+    switch($contact['network']) {
+    
+        case NETWORK_DFRN:
+            if ($mail) {
+                $item['body'] = ...
+                $atom = dfrn::mail($item, $owner);
+            } elseif ($fsuggest) {
+                $atom = dfrn::fsuggest($item, $owner);
+                q("DELETE FROM `fsuggest` WHERE `id` = %d LIMIT 1", intval($item['id']));
+            } elseif ($relocate)
+                $atom = dfrn::relocate($owner, $uid);
+    [...]
+```
+
+This is real "include/delivery.php" unchanged, but as the code is declared to be in "Friendica" namespace, you don't need to write it when you need to use the "dfrn" class.
+But if you want to use classes from another library, you need to use the full namespace, e.g.
+
+```
+    <?php
+    namespace \Frienidca;
+    
+    class Diaspora {
+      public function md2bbcode() {
+        $html = \Michelf\MarkdownExtra::defaultTransform($text); 
+      }
+    }
+```
+
+if you use that class in many places of the code and you don't want to write the full path to the class everytime, you can use the "use" php keyword
+
+```
+    <?php
+    namespace \Frienidca;
+    
+    use \Michelf\MarkdownExtra;
+    
+    class Diaspora {
+      public function md2bbcode() {
+        $html = MarkdownExtra::defaultTransform($text); 
+      }
+    }
+```
+
+Note that namespaces are like paths in filesystem, separated by "\", with the first "\" being the global scope.
+You can go more deep if you want to, like:
+
+```
+    <?php
+    namespace \Friendica\Network;
+    
+    class DFRN {
+    }
+```
+
+or
+
+```
+    <?php
+    namespace \Friendica\DBA;
+    
+    class MySQL {
+    }
+```
+
+So you can think of namespaces as folders in a unix filesystem, with global scope as the root ("\").

---DESCRIPTION--
-<p>
-    If HTML Purifier's tag set is unsatisfactory for your needs, you
-    can overload it with your own list of tags to allow.  Note that this
-    method is subtractive: it does its job by taking away from HTML Purifier
-    usual feature set, so you cannot add a tag that HTML Purifier never
-    supported in the first place (like embed, form or head).  If you
-    change this, you probably also want to change %HTML.AllowedAttributes.

-    <strong>Warning:</strong> If another directive conflicts with the
-    elements here, <em>that</em> directive will win and override.

-/**
- * Takes a well formed list of tokens and fixes their nesting.

- * HTML elements dictate which elements are allowed to be their children,

- * The second objective is to ensure that explicitly excluded elements of
- * an element do not appear in its children.  Code that accomplishes this
- * task is pervasive through the strategy, though the two are distinct tasks
- * and could, theoretically, be seperated (although it's not recommended).
