Moodle: Change course name in breadcrumb

Hello,

If you want to modify the text of the a course in the breadcrumb you can do this (tested in Moodle 3.2):

Add this function in your file lib.php of your local plugin:

function local_yourlocalplugin_extend_navigation(global_navigation $nav) {
    global $COURSE, $CFG;

    if (isset($COURSE->id) && $COURSE->id > 0) {
        $coursenode = $nav->find($COURSE->id, navigation_node::TYPE_COURSE);
        if ($coursenode) {
                $coursenode->text .= ' My extra text';
        }
    }
}

Best regards!
