python plugin management, simplified.

Documentation

Source Code

Library under development. Contains rough edges/unfinished functionality. API subject to changes.

Installation

pip install pluginmanager

-or-

pip install git+https://github.com/benhoff/pluginmanager.git

Quickstart

from pluginmanager import PluginInterface

plugin_interface = PluginInterface()
plugin_interface.set_plugin_directories(plugin_directory_path)
plugin_interface.collect_plugins()

plugins = plugin_interface.get_instances()

Custom Plugins

The quickstart will only work if you subclass IPlugin for your custom plugins.

import pluginmanager

class MyCustomPlugin(pluginmanager.IPlugin):
    def __init__(self):
        self.name = 'custom_name'
        super().__init__()

Or register your class as subclass of IPlugin.

import pluginmanager

pluginmanager.IPlugin.register(YourClassHere)

Add Plugins Manually

Add classes.

import pluginmanager

class CustomClass(pluginmanager.IPlugin):
    pass

plugin_interface = pluginmanager.PluginInterface()
plugin_interface.add_plugins(CustomClass)

plugins = plugin_interface.get_instances()

Alternatively, add instances.

import pluginmanager

class CustomClass(pluginmanager.IPlugin):
    pass

custom_class_instance = CustomClass()

plugin_interface = pluginmanager.PluginInterface()
plugin_interface.add_plugins(custom_class_instance)

plugins = plugin_interface.get_instances()

pluginmanager is defaulted to automatically instantiate unique instances. Disable automatic instantiation.

import pluginmanager

plugin_interface = pluginmanager.PluginInterface()
plugin_manager = plugin_interface.plugin_manager

plugin_manager.instantiate_classes = False

Disable uniqueness (Only one instance of class per pluginmanager)

import pluginmanager

plugin_interface = pluginmanager.PluginInterface()
plugin_manager = plugin_interface.plugin_manager

plugin_manager.unique_instances = False

Filter Instances

Pass in a class to get back just the instances of a class

import pluginmanager

class MyPluginClass(pluginmanager.IPlugin):
    pass

plugin_interface = pluginmanager.PluginInterface()
plugin_interface.add_plugins(MyPluginClass)

all_instances_of_class = plugin_interface.get_instances(MyPluginClass)

Alternatively, create and pass in your own custom filters. Either make a class based filter

# create a custom plugin class
class Plugin(pluginmanager.IPlugin):
    def __init__(self, name):
        self.name = name

# create a custom filter
class NameFilter(object):
    def __init__(self, name):
        self.stored_name = name

    def __call__(self, plugins):
        result = []
        for plugin in plugins:
            if plugin.name == self.stored_name:
                result.append(plugin)
        return result

# create an instance of our custom filter
mypluginclass_name_filter = NameFilter('good plugin')

plugin_interface = pluginmanager.PluginInterface()
plugin_interface.add_plugins([Plugin('good plugin'),
                              Plugin('bad plugin')])

filtered_plugins = plugin_interface.get_instances(mypluginclass_name_filter)

Or make a function based filter

# create a custom plugin class
class Plugin(pluginmanager.IPlugin):
    def __init__(self, name):
        self.name = name

# create a function based filter
def custom_filter(plugins):
    result = []
    for plugin in plugins:
        if plugin.name == 'good plugin':
            result.append(plugin)
    return result

plugin_interface = pluginmanager.PluginInterface()
plugin_interface.add_plugins([Plugin('good plugin'),
                              Plugin('bad plugin')])

filtered_plugins = plugin_interface.get_instances(mypluginclass_name_filter)
