Defines the basic interface for a plugin manager that also keeps track of versions of plugins


class yapsy.VersionedPluginManager.VersionedPluginInfo(plugin_name, plugin_path)

Gather some info about a plugin such as its name, author, description…

class yapsy.VersionedPluginManager.VersionedPluginManager(decorated_manager=None, categories_filter={'Default': <class 'yapsy.IPlugin.IPlugin'>}, directories_list=None, plugin_info_ext='yapsy-plugin')

Handle plugin versioning by making sure that when several versions are present for a same plugin, only the latest version is manipulated via the standard methods (eg for activation and deactivation)

More precisely, for operations that must be applied on a single named plugin at a time (getPluginByName, activatePluginByName, deactivatePluginByName etc) the targetted plugin will always be the one with the latest version.


The older versions of a given plugin are still reachable via the getPluginsOfCategoryFromAttic method.


DEPRECATED(>1.8): Please consider using getPluginsOfCategory instead.

Return the list of all plugins belonging to a category.


Access the older version of plugins for which only the latest version is available through standard methods.

loadPlugins(callback=None, callback_after=None)

Load the candidate plugins that have been identified through a previous call to locatePlugins.

In addition to the baseclass functionality, this subclass also needs to find the latest version of each plugin.


Set the categories of plugins to be looked for as well as the way to recognise them.

Note: will also reset the attic toa void inconsistencies.
