earwigbot 0.4

History

Development began, based on Pywikibot, in early 2009. Approval for its first task, a copyright violation detector, was carried out in May, and the bot has been running consistently ever since. It currently handles several ongoing tasks ranging from statistics generation to category cleanup, and on-demand tasks such as WikiProject template tagging. Since it started running, the bot has made over 300,000 edits.

The current version of its codebase began development in April 2011, moving away from Pywikibot to a custom framework.

Installation

This package contains the core earwigbot, abstracted to be usable and customizable by anyone running a bot on a MediaWiki site. Since it is modular, the IRC components can be disabled if desired. IRC commands and bot tasks specific to my instance of EarwigBot that I don’t feel the average user will need are available from the repository earwigbot-plugins.

git clone https://github.com/earwig/earwigbot.git
cd earwigbot
python3 -m venv venv
. venv/bin/activate
pip install -e '.[crypto,sql,copyvios,dev]'

Setup

The bot stores its data in a “working directory”, including its config file and databases. This is also the location where you will place custom IRC commands and bot tasks, which will be explained later. It doesn’t matter where this directory is, as long as the bot can write to it.

Start the bot with earwigbot path/to/working/dir, or just earwigbot if the working directory is the current directory. It will notice that no config.yml file exists and take you through the setup process.

There is currently no way to edit the config.yml file from within the bot after it has been created, but you should be able to make any necessary changes yourself.

After setup, the bot will start. This means it will connect to the IRC servers it has been configured for, schedule bot tasks to run at specific times, and then wait for instructions (as commands on IRC). For a list of commands, say “!help” (commands are messages prefixed with an exclamation mark).

You can stop the bot at any time with Control+C, same as you stop a normal Python program, and it will try to exit safely. You can also use the “!quit” command on IRC.

Customizing

The bot’s working directory contains a commands subdirectory and a tasks subdirectory. Custom IRC commands can be placed in the former, whereas custom wiki bot tasks go into the latter. Developing custom modules is explained below, and in more detail through the bot’s documentation or in the docs/ dir.

Note that custom commands will override built-in commands and tasks with the same name.

irc:
    frontend:
        nick: MyAwesomeBot
        channels:
            - "##earwigbot"
            - "#channel"
            - "#other-channel"

The Wiki Toolset

EarwigBot’s answer to the Pywikibot is the Wiki Toolset (earwigbot.wiki), which you will mainly access through bot.wiki.

bot.wiki provides three methods for the management of Sites: get_site(), add_site(), and remove_site(). Sites are objects that simply represent a MediaWiki site. A single instance of EarwigBot (i.e. a single working directory) is expected to relate to a single site or group of sites using the same login info (like all WMF wikis with CentralAuth).

Load your default site (the one that you picked during setup) with site = bot.wiki.get_site().

Not all aspects of the toolset are covered in the docs. Explore its code and docstrings to learn how to use it in a more hands-on fashion. For reference, bot.wiki is an instance of earwigbot.wiki.SitesDB tied to the sites.db file in the bot’s working directory.
