A very easy to use, simple to extend jabber bot framework.

Project Description


mtj.jibber is a package that can be used to streamline the process of providing automagical useless bantering onto your friendly neighbourhood rooms (multi-user chat or MUCS) on all the Jabber (XMPP) servers.

It’s jibber jabber time.


This is a piece of cake. Get a virtualenv running, and do this:

$ pip install mtj.jibber

This installs the latest stable release version of this package from the Python Package Index (pypi). If you wish to do so, you should follow the documentation on that index page.

Alternatively, if you want to hack and develop on this, please feel free to make a fork and clone that or clone directly from this fork. Naturally I will assume you got a virtualenv setup, too:

$ git clone
$ cd mtj.jibber
$ python develop

Of course, in that case you should follow the documentation as listed in the README.rst found at the root of the source repository.

Quick Start Tutorial

The original reason for making this is to allow much modularity and very easy usage. To demonstrate this, get this package installed and get the default configuration files generated like so:

$ jibber --gen-config server > server.config.json
$ jibber --gen-config client > client.config.json

Now you can start the bot like so:

$ jibber server.config.json client.config.json debug
Starting interactive shell. `bot` is bound to the MucBot object.
Try calling bot.connect() to connect to the server specified in config file.
Note: process will NOT terminate if bot.is_alive() is False!
Alternatively call bot_test() to test here locally.

So the interactive shell should have started like it did above if this package was installed correctly. Now you can issue the command:

>>> bot_test()
Test client ready; call client('Hello bot') to interact.

A new function is provided for you to interact with the bot, you can just follow the prompt:

>>> client('Hello bot')
2013-11-01 00:00:51,316 INFO mtj.jibber.testing hi Tester

The test client doesn’t have any connection to any servers, so all the interactions will just end up being shown in the log at the INFO level. This can be useful for your final integration testing.

Of course, you want the bot to do more than this, let’s look at the client config file.

Client Config

The packages object contain the list of “packages” that will be instantiated for the bot to use. The keys follow:

The full path to the class (or any callables that return an instance of one).
The keyword arguments that will be passed into that call.
A 2-tuple (well, list, this is JSON after all) of regex string, method. The method is a callable attribute will be provided by the object returned by the calling package(**kwargs). The regex can contain some string format keywords, most notably nickname which is the nickname assigned to the bot. Commands only get executed to the maximum commands limit, and the bot will not try to match something it says with the ones here.
Exactly like commands, except the bot will try to comment on things it says up to a limit. Default is sane, I am not going to teach you how to override that because hilarious infinite loops can happen
All messages passed to the bot will be listened, but no output will be sent.
A list of objects that will be used to instantiate repeated commands at a delay. This is somewhat advanced and not covered here. The test cases might explain how this works.

The commands_max_match can be defined to match up to that amount of commands, i.e. the commands will not further cascade down once that amount is reached. This is useful if you have a situation where a significant amount of triggers overlap.

Now, you might want to extend the bot to do more. Let’s try something adding something else to the list of packages (remember your JSON comma placements!):

    "package": "",
    "kwargs": {"items": [
        "red!", "orange!", "yellow!", "green!", "blue!", "violet!"]},
    "commands": [
        ["^rainbow (color|colour)!$", "play"]

The PickOne class has a play method that picks one of the items with an equal chance for all. In this case a command that matches either rainbow color! or rainbow colour! and respond with one of the six items specified. Demo run:

>>> client('rainbow color!')
2013-11-01 00:01:31,965 INFO mtj.jibber.testing violet!
>>> client('rainbow colour!')
2013-11-01 00:01:33,981 INFO mtj.jibber.testing orange!

There is another one that is similar:

    "package": "",
    "kwargs": {"chance_table": [
        [0.125, "%(mucnick)s: BOOM"], [1, "%(mucnick)s: click"]
    "commands": [
        ["^%(nickname)s: rr$", "play"]

This one is similar to PickOne, except with the allowance of a chance which is specified in the first element of the 2-tuple. The roll is a random real number between 0 and 1 inclusive, and thus the matching is done by cascading downwards on that list for a match. Match is done by checking whether the number is less than the chance number. If match, the corresponding result is returned. Demo run:

>>> client('bot: rr')
2013-11-01 00:02:11,647 INFO mtj.jibber.testing Tester: click
>>> client('bot: rr')
2013-11-01 00:02:12,714 INFO mtj.jibber.testing Tester: click
>>> client('bot: rr')
2013-11-01 00:02:12,822 INFO mtj.jibber.testing Tester: click
>>> client('bot: rr')
2013-11-01 00:02:13,006 INFO mtj.jibber.testing Tester: BOOM

Also note how it is possible to specify string format keywords here. The most useful one would be mucnick, which correspond to the user who sent the line. These are based on the msg stanzas used by sleekxmpp so for all details check the relevant documentation (or clever breakpoint placements).

For completeness, if you had followed the above instructions your configuration should look similar to the output generated by this command:

$ jibber --gen-config client_example

Oh yeah, you can naturally develop your own modules that do things you want your bot to do. Feel free to use the classes in as your starting point, and as a further example on how to build a package with your custom commands, please take a look at mtj.jibberext.

Server Config

The server configuration should be simple. It is done this way to split out the connection settings from the actual bot settings you may wish to pass onto your friends. The keys as follows:

The jid that is used to connect to the server.
Password associated with the jid
The host used to connect to the server. Optional as this can be derived from jid, but quite often the actual host is often different so this usually needs to be specified.
Defaults to 5222.

Remaining keys are passed into the connect method for a sleekxmpp client instance. Refer to documentations over there if you are curious on what they are.

Doing it live

Fill out the correct information (the jid/password/host and the rooms you wish your bot to join) and then you can call bot.connect()! Alternatively you can replace debug with fg to have it connect right away and ditch the interactive shell.


If you find yourself constantly restarting the bot completely because a single line of code or setting was changed and also finding this process tiresome, there is a helper method in the debug shell that will reload the client configuration file and all modules with the associated timers and triggers with just one function call:

>>> bot_reinit()
Successfully reinitialized bot configuration and modules.

Do note: this function is potentially unsafe. Syntax errors in the configuration or the modules that got added after the bot has started will be raised as exceptions and loading is aborted, leaving the bot in a fresh but partially instantiated state. This may or may not cause problems specific to the code/modules you have loaded with the bot.


0.4 - 2015-09-12

  • Fully require the bot argument for all methods.
  • Support hooking up handlers to lower level events, making it possible to hook that up via the config file to available module/class paths. This is implemented in the presence module.
  • For the mean time Presence is the new base Handler for the lower level events.
  • First such handler is the automatic rejoin when bot is no longer in a channel, implemented in the Muc class.
  • Another one is greeter, implemented in the MucGreeter class.
  • The Command class is now a subclass of Handler; that is now the class that will be checked. In the future this requirement may be dropped once validation of argument signature for the provided callables can be done.
  • A LastActivity feature; can be used as a !seen trigger to get back a rough idea on when the user was last seen. This intends to be a demo implementation.
  • Test client class now supports scheduling properly; clear method now works as intended.
  • Other minor cleanup and updated tests.

0.3 - 2014-10-08

  • MucChatBot.send_message now much more resistant to malformed messages generated by package method, and now allow overriding of both mbody and mhtml arguments which will cascade down to the real send_message method, if bot authors want complete output control.
  • Consistently handle lists that may be generated by package_methods in the same way as a single text or dict.
  • No longer will assign a reference to bot for every instances of Command class.

0.2 - 2014-02-27

  • Private chat message handling for private message commands.
  • Core configuration file generation from the jibber shell command.
  • Helper method for dynamic module reloading within debug mode.

0.1 - 2013-11-14

  • Core functions implemented, including connect to XMPP server as a muc client, and to provide trigger handlers and dynamic module/object loaders so those triggers can make something happen.
