Installation

Dependencies

$ sudo apt-get install python2.6
  • I also need a modified version of wikitools to use the MediaWiki API. Comes with a separate hand-crafted module called wikiUpload to allow file uploading without MediaWiki 1.16. On Ubuntu:
$ wget 'http://upload.gaiatools.com/files/wikitools_mod_5.7z'
$ p7zip -d wikitools*.7z && wikitools*.7z
$ mv wikiUpload.py MultipartPostHandler.py `dirname "/path/to/bot.py"`
$ cd wikitools*
$ sudo python2.6 setup.py install
  • (Optional) cpulimit can be used to limit the bot's often-high CPU usage when applying filters to a lengthy page, to ensure sufficient resources to other programs running concurrently on the server. This does slow the bot down but makes it act nicer to others, which is welcome on a shared host. On Ubuntu:
$ sudo apt-get install cpulimit
  • (Optional) pngcrush can be used to crush PNG images in file filters. Without it, images will not be considered for crushing. On Ubuntu:
$ sudo apt-get install pngcrush

That's it!

File structure

  • botConfig.py: The bot's configuration. A sample configuration file is given below.
  • bot.py: The bot's core. Full source is given below. Make sure to make it executable:
chmod +x bot.py

Both files have to be in the same directory. To run the bot, assuming Python is in your path and that you are in the bot's source directory:

./bot.py
