Developer Area/Plugin migration between Mahara 1.3 and 1.4

Mahara 1.4 has some changes to the menu bars.

The table below has examples of the code differences required for plugins in Mahara 1.3 and Mahara 1.4.

This may help anyone upgrading a plugin to work in Mahara 1.4 or backporting a plugin to Mahara 1.3

It is not comprehensive. Feel free to add further examples

Plugin	File	Mahara 1.3	Mahara 1.4
blocktype /externalfeed	lib.php	public static function get_categories() { return array('feeds'); }	public static function get_categories() { return array('external'); }
blocktype /externalvideo	lib.php	public static function get_categories() { return array('fileimagevideo'); }	public static function get_categories() { return array('external'); }
artefact /plans	lib.php	public static function menu_items() { return array( array( 'path' => 'myportfolio/plans', 'url' => 'artefact/plans/', 'title' => get_string('myplans', 'artefact.plans'), 'weight' => 40, ), ); }	public static function menu_items() { return array( 'content/plans' => array( 'path' => 'content/plans', 'url' => 'artefact/plans/', 'title' => get_string('Plans', 'artefact.plans'), 'weight' => 60, ), ); }
artefact/plans	index.php new.php plan.php	define('MENUITEM', 'myportfolio/plans');	define('MENUITEM', 'content/plans');

In some cases, it may be worth considering conditional statements to enable a plugin to work with either Mahara 1.3 or 1.4. For example

public static function get_categories() {
    require_once(get_config('libroot') . 'version.php');
    $release = $config->release;
        if ($release < 1.4) {
            return array('feeds');
        }
    return array('external');
}
