pybot

This is a modular, plugin-based IRC bot written in Python. Plugins can bedynamically loaded and unloaded at runtime. A design goal is the abillity to develop plugins without being able to crash the bot.

Plugins have a simple, easy to pick up API. All events, commands, and triggers use a simple decorator convention.

Clone with: git clone --recursive https://github.com/jkent/pybot.git

Dependencies

Pybot is designed and tested to run under Python 3. Python 2 is no longer supported. Dependencies are listed in requirements.txt.

Configuring

You need to copy config.yaml.example to config.yaml and edit it to your liking.

The below examples in the Plugins section assume directed_triggers is False. Directed triggers start with the bot's name, followed by a colon or comma, and finally the command and any arguments. The other option, classic triggers, take a ! followed by the command and any arguments. The default option is to use directed triggers, so multiple bots can peacefully coexist.

• config.yaml:

  my_network:
    host: localhost
    port: 6667
    ssl: false
  
    plugins:
      base:
        connect_password: null
        nickname: pybot
        username: pybot
        realname: Python IRC bot - http://git.io/M1XRlw
        nickserv_password: null
        channels:
            - '#dev'
  

Running

Pybot can be run as either a package or using its pybot.py script. It also comes with a shell script, run.sh that will setup a python virtual environment and dependencies for you.

Plugins

• Configuration:

  anyurl:
    blacklist:
      - '^https://www.google.com/.*$'

  !math func([var[, ...]])=[expr]
  !math workbook [name]
  !math varlist

For Developers

Plugins

Here's a simple "Hello world" style plugin:

from pybot.plugin import *

class Plugin(BasePlugin):
    @hook
    def hello_trigger(self, msg, args, argstr):
        msg.reply('Hello %s!' % (argstr,))

You would call the trigger on IRC via either:

!hello world

or if directed (conversational) style triggers are enabled:

pybot, hello world

To which the bot would reply:

<pybot> Hello world!

Hooks

There are five types of hooks:

• event
• command
• trigger
• timestamp
• url

All except for timestamp hooks can be used via the @hook decorator. @hook is a smart decorator that uses the naming convention of your method to determine the name and type of the hook. Alternatively, it can be called as @hook(names) and @hook(type, names).

Timestamp hooks can be created 3 different ways: one-shot timeouts, one-shot timers, and repeating intervals. They are discussed in more detail with the Bot class.

Bot class

Anything that you may need to access should be accessable from the bot class. Plugins get a reference to the bot instance they are running on (self.bot).
