Full commit
======
pmxbot
======

pmxbot is an IRC bot written in python. Originally built for internal use,
it's been sanitized and set free upon the world. You can find out  more details
on the website, http://bitbucket.org/yougov/pmxbot, and especially the wiki
https://bitbucket.org/yougov/pmxbot/wiki/Home


Commands
========
pmxbot listens to commands prefixed by a '!'
If it's a command it knows it will reply, take an action, etc.
It can search the web, quote you, track karma, make decisions,
and do just about anything else you could want. It stores logs and quotes
and karma in a sqlite or MongoDB
database, and there's a web interface for reviewing the logs and karma.

Contains
========
pmxbot will respond to things you say if it detects words and phrases it's
been told to recognize. For example, mention sql on rails.

Requirements
============

`pmxbot` requires Python 2.6 or 2.7. It also requires a few python
packages as defined in setup.py.

If using the MongoDB backend, it requires pymongo (otherwise, sqlite will
be used).

Testing
=======

`pmxbot` includes a basic nose test suite that does some functional tests
with an
included TCL IRC daemon, and some basic unit tests as well. Just run them
from
the pmxbot root directory with "nosetests" (requires nose) or "py.test"
(requires pytest) and it should do it all for you.

You'll need TCL for the functional tests not to be skipped.

Configuration
=============
Configuration is based on very easy YAML files. Check out config.yaml in the
source tree for an example.

Usage
=====
Once you've setup a config file, you just need to call ``pmxbot config.yaml``
and it will join and connect. We recommend running pmxbot under
daemontools, upstart, supervisord, or your favorite supervisor to make it
automatically restart if it crashes (or terminates due to a planned
restart).


Custom Features
===============

Setuptools Entry Points Plugin
------------------------------

To create a setuptools (or distribute or compatible packaging tool)
entry point plugin, package your modules using
the setuptools tradition and install it alongside pmxbot. Your package
should define an entry point in the group `pmxbot_handlers` by including
something similar to the following in the package's setup.py::

    entry_points = {
        'pmxbot_handlers': [
            'plugin_name = mylib.mymodule:initialize_func',
        ],
    },

During startup (and after loading the traditional script-based plugins),
pmxbot will load `mylib.mymodule` and call `initialize_func` from that
module (with no parameters).
`plugin_name` can be anything, but should be a name suitable to
identify the plugin. It is not necessary that initialize_func do
anything at all, but it must be present, and will be called during
startup.

Within the script you'll want to import the decorates you need to use with:
`from pmxbot.botbase import command, contains, execdelay, execat`. You'll then
decorate each function with the appropriate line so pmxbot registers it.

A command (!g) gets the @command decorator::

  @command("tinytear", aliases=('tt', 'tear', 'cry'), doc="I cry a tiny tear for you.")
  def tinytear(client, event, channel, nick, rest):
  	if rest:
  		return "/me sheds a single tear for %s" % rest
  	else:
  		return "/me sits and cries as a single tear slowly trickles down its cheek"

A response (when someone says something) uses the @contains decorator::

  @contains("sqlonrails")
  def yay_sor(client, event, channel, nick, rest):
  	karmaChange(botbase.logger.db, 'sql on rails', 1)
  	return "Only 76,417 lines..."

For an example of how to implement a setuptools-based plugin, see
the `wolframalpha plugin
<http://bitbucket.org/yougov/pmxbot-wolframalpha>`_.

Web Interface
=============
pmxbot includes a web server for allowing users to view the logs, read the
help, and check karma. You specify the host, port, base path, logo, title,
etc with the same YAML config file. Just run like ``pmxbotweb config.yaml``
and it will start up. Like pmxbot, use of a supervisor is recommended to
restart the process following termination.
