From 1348c6e81995d9cae5ad4a4803723750ecb462c2 Mon Sep 17 00:00:00 2001 From: Evan Prodromou Date: Sun, 3 Jan 2010 11:02:36 -1000 Subject: Expand SamplePlugin to show other best practices I modified the SamplePlugin to show how to do some real processing, adding a data class and an action class and modifying the main menu to link to the new action. I added documentation comments to all the methods and made sure the modules were PHPCS-clean. --- plugins/Sample/hello.php | 166 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 166 insertions(+) create mode 100644 plugins/Sample/hello.php (limited to 'plugins/Sample/hello.php') diff --git a/plugins/Sample/hello.php b/plugins/Sample/hello.php new file mode 100644 index 000000000..0cfd8a1c3 --- /dev/null +++ b/plugins/Sample/hello.php @@ -0,0 +1,166 @@ + + * @license http://www.fsf.org/licensing/licenses/agpl.html AGPLv3 + * @link http://status.net/ + * + * StatusNet - the distributed open-source microblogging tool + * Copyright (C) 2009, StatusNet, Inc. + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU Affero General Public License as published by + * the Free Software Foundation, either version 3 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
