PyPlugins - is a plugins loader for Bukkit/Spigot (PaperMC) to load plugins are written on Python 2.7 (via Jython 2.7.2).

The creation of the plugin was inspired by Macuyiko/minecraft-python, masteroftime/Python-Plugin-Loader and cyberlis/pploader.

Available two versions of the loader plugin:

• with included Jython (recommended to use);
• without Jython (requires inclusion of jython.jar in the folder server/lib/)

Steps:

1. Put PyPlugins-with[out]-Jython-*.*.*.jar (download link) in your server/plugins/ directory
2. Run server

1. Put the <PluginName>.pyplugin sources (directory or zip file) in your server/plugins/ directory
2. Run server

The PyPlugins contains a few way to create plugin for Spigot on Python.

It's can be:

1. Clear Java-like approach (just write the code as a Java plugin, but using Python);
2. Using internal pyplugins-framework (recomended);

First approach examples you can see here.

The next paragrphes about internal pyplugins-framework.

Your plugin can use the following paths to the plugin source code:

• A zip whos name ends in either .pyplugin.zip, _pyplugin.zip or just .pyplugin
• A directory whose name ends in .pyplugin or _pyplugin (actual for windows users)

Zips with the .pyplugin extension are recommended if you release any plugins. When you use a zip, your must specify your own metadata; it will not allow guessed metadata.

When using a dir or a zip, your zip or dir must contain a main python file (with names: main.py, plugin.py, __main__.py or __init__.py) and a plugin.yml configuration file containing metadata (see the following section).

Plugins require metadata. The absolute minimum metadata is a name version and main class. The 'main' field of plugin metadata has special behavior:

• the main is used to search for a main class before searching the default class name.

plugin.yml is able to set all metadata fields that exist in bukkit, and should be used for all plugins that you release. plugin.yml is used in all java plugins (as it is the only option for java plugins). as such, opening up java plugin jars is a good way to learn what can go in it. Or you can read about it here http://wiki.bukkit.org/Plugin_YAML Here isan example of plugin.yml:

name: SamplePlugin
main: SampleClass
version: 0.1-dev
commands:
    samplecommand:
        description: send a sample message
        usage: /<command>

Summary of fields:

• "main" - name of main python file or name of main class
• "name" - name of plugin to show in /plugins list and such. used to name the config directory. for this reason it must not equal the full name of the plugin file.
• "version" - version of plugin. shown in errors, and other plugins can access it
• "website" - mainly for people reading the code

Minimum requirements:

• Main class have to be extended from PythonPlugin class. (You don't have to import it, because it is auto imported on startup of loader plugin).
• Your main class must have onEnable() and onDisable() methods.

The same as Java-like minimum requirements:

• Main class have to be extended from PythonPlugin class. (You don't have to import it, because it is auto imported on startup of loader plugin).
• Your main class must have onEnable() and onDisable() methods.

Handlers are available to easily create your Python plugin:

• PythonCommandExecutor class (CommandsAPI)

  You can inherit your own PluginNameCommandExecutor class from PythonCommandExecutor to make handlers for "executeCommand" and "onTabComplete" actions (the command must be declared in plugin.yml). Just create methods for these actions and make the commands attribute of your PluginNameCommandExecutor class with instances of PyCommand class (with command and methods names). Also can be used as commands list acceptor (functional approach) and able to get PyCommands as first argument on initialization.

• PythonListener class (EventsAPI)

  Similar to CommandsAPI, but with PythonListener class as parent, the listeners attribute (for save your handlers) of class with instances of PyEventHandler (requires name of method to execute, Bukkit event object and (optional) Bukkit ptiority object). Also can be used as listener list acceptor (functional approach) and able to get PyEventHandlers as first argument on initialization.

NOTE:

bStats version 2.x.x does not allow the use of the org.bukkit.plugin.Plugin class for plugins and requires org.bukkit.plugin.java.JavaPlugin.

PyPlugins currently uses bStats 1.8, and needs to be added from the local jar:

mvn install:install-file -Dfile=bstats-bukkit-1.8.jar -DgroupId=org.bstats -DartifactId=bstats-bukkit -Dversion=1.8 -Dpackaging=jar
