Plugins

|
=======
|
|
|
|
Beginning with the 0.7.x branch, StatusNet has supported a simple but
|
|
powerful plugin architecture. Important events in the code are named,
|
|
like 'StartNoticeSave', and other software can register interest
|
|
in those events. When the events happen, the other software is called
|
|
and has a choice of accepting or rejecting the events.
|
|
|
|
In the simplest case, you can add a function to config.php and use the
|
|
Event::addHandler() function to hook an event:
|
|
|
|
function AddGoogleLink($action)
|
|
{
|
|
$action->menuItem('http://www.google.com/', _('Google'), _('Search engine'));
|
|
return true;
|
|
}
|
|
|
|
Event::addHandler('EndPrimaryNav', 'AddGoogleLink');
|
|
|
|
This adds a menu item to the end of the main navigation menu. You can
|
|
see the list of existing events, and parameters that handlers must
|
|
implement, in EVENTS.txt.
|
|
|
|
The Plugin class in lib/plugin.php makes it easier to write more
|
|
complex plugins. Sub-classes can just create methods named
|
|
'onEventName', where 'EventName' is the name of the event (case
|
|
matters!). These methods will be automatically registered as event
|
|
handlers by the Plugin constructor (which you must call from your own
|
|
class's constructor).
|
|
|
|
Several example plugins are included in the plugins/ directory. You
|
|
can enable a plugin with the following line in config.php:
|
|
|
|
addPlugin('Example', array('param1' => 'value1',
|
|
'param2' => 'value2'));
|
|
|
|
This will look for and load files named 'ExamplePlugin.php' or
|
|
'Example/ExamplePlugin.php' either in the plugins/ directory (for
|
|
plugins that ship with StatusNet) or in the local/ directory (for
|
|
plugins you write yourself or that you get from somewhere else) or
|
|
local/plugins/.
|
|
|
|
Plugins are documented in their own directories.
