xbotlib

XMPP bots for humans

status: experimental

A friendly lightweight wrapper around slixmpp for writing XMPP bots in Python. The goal is to make writing and running XMPP bots easy and fun. xbotlib is a single file implementation which can easily be understood and extended. It provides a small API surface which reflects the slixmpp way of doing things.

Install

$ pip install xbotlib

Example

Put the following in a echo.py file.

from xbotlib import EchoBot

EchotBot()

And then python echo.py. You will be asked a few questions like which account details your bot will be using.

This will generate a bot.conf file in the same working directory for further use.

Here's the code for the EchoBot.

class EchoBot(Bot):
    """Gives back what you sent it.

    Just direct message the bot and see if you get back what you sent. It also
    works in group chats but in this case you need to summon the bot using its
    nickname Usually like so.

    echobot:foo

    """

    def react(self, message):
        """Send back what we get."""
        if message.type == "chat":
            self.reply(message.body, to=message.sender)

All examples

• EchoBot: Sends back what you sent it
• WhisperBot: Pseudo-anonymous whispering in group chats

See xbotlib.py for all example bots.

API Reference

When writing your own bot, you always sub-classes the Bot class provided from xbotlib. All underling functions can be extended. For example, if you want to enable more plugins or add different functionality. If something feels awkward then please raise a ticket for that. Seamlessness is still a bitch but we're trying anyway.

Bot.react(message)

A function which you define in your bot implementation in order to respond to chat messages. You can respond to both direct messages and group chat messages in this function by checking the message.type which can be either chat or groupchat.

Arguments:

• message: sent message and metadata (see message reference below)

Bot.reply(body, to=None, room=None)

Send back a response to a direct chat message.

Arguments:

• body: the message to send
• to: which user account to reply to (direct chat)
• room: which room to reply to (group chat)

SimpleMessage

A simple message format. This is the type that you work with when your function accepts a message argument.

Attributes:

• body: the body of the message
• sender: the sender of the message
• receive: the receive of the message
• nickname: the nickname of the sender
• type: the type of message (chat or groupchat)

Configure your bot

Using the environment

You can pass the --no-input option to your script invocation (e.g. python bot.py --no-input).

xbotlib will try to read the following configuration values from the environment.

• XBOT_JID: The username of the bot account
• XBOT_PASSWORD: The password of the bot account
• XBOT_ROOM: The room that the bot can join
• XBOT_NICK: The nickname that the bot uses
