Pyrus relies upon PHP5's autoloading capabilities to automatically load a plugin class. All plugins should include the <autoloadpath> element to specify a path relative to the php_dir location for the plugin registry. For plugin classes that conform to PEAR2 standards, the autoloadpath should be an empty string:


The pyrus autoloader will automatically replace _ and the namespace separator \ with DIRECTORY_SEPARATOR and append .php to determine the class name to load. To instruct Pyrus to prepend a particular relative path, put this path in the <autoloadpath> element. As an example, the following XML will prompt Pyrus to load the file /home/user/.pear/MyPackage/customcommands/Command/Line/Obj.php if the user's plugins_dir is /home/user/.pear:


The <class> element is used by Pyrus to determine which object to instantiate. If <class> is:


Pyrus will instantiate an object of class FooBar_Willy\Dilly.
