MediaWiki and OmahaWiki.org

March 2, 2007

A ways back in the past I had a MediaWiki install at WikiOmaha.org with the hopes that a wiki could be formed for the omaha community, by the omaha community (sound familiar?). Anyway, I never really did much with it, and a few days ago a professor from Creighton contacted me about my domain and pooling resources.

He has created OmahaWiki.org which WikiOmaha.org now re-directs to. He is having students flesh it out. I came into the picture to help set up some bots to manage the content.

It turns out there is a cool framework for MediaWiki’s called the “Python Wikipedia Robot Framework” that is written in python. I got the scripts working on my machine and then I turned my attention to writing a bot that would do a word-count on every page, and add a stub to that page if it was under a given threshold.

I had forgotten how awesome Python is. It really is a good language, I just wish I had call to use it every once in a while. Anyway, here is my Python bot for that framework. You can grab a file version here

#!/usr/bin/python
# -*- coding: utf-8  -*-
"""
-----// Stub Adder //------------------------------------------------------
File: jmh_addstubs.py
Version: 1.0

This bot will iterate through all pages of the wiki and append a generic
stub ('{{Stub}}') to them if they do not have one already and have under
a given number of "words" in them.  Words, here, are counted as _any_ series
of characters seperated by a space.  The default maximum number of words
that the bot will work on is 5, so it is recommended that you pass it a more
realistic value.

Call

python wordcount.py

to have your change be done on all pages of the wiki. If that takes too
long to work in one stroke, run:

python wordcount.py Pagename

to do all pages starting at pagename.

There are two command line options:

-dryrun
    This will check and notify you but will not actually change anything.
    
-words=XX
  This is the word threshold. Replace XX with the biggest wordcount that you
  want the bot to append stubs to.
