Manual:MediaWiki-Recent Changes-IRCBot
- Not to be confused with Manual:Wikibot, a configurable PHP-based bot framework.
Einführung
[edit]Modified the Manual:Simple IRC RC Bot created by Thrasher6670. This bot does not require ircii. It is completely self contained. It displays recent changes of your wiki to an IRC channel.
Note: Most up to date version of this extension can be found at: http://www.chekmate.org/wiki/index.php/Projects

Installation
[edit]Requirements
[edit]This Perl script also requires POE (and the IRC Component), which you may find was not packaged with your system. Not to worry! Very easy to install.
POE may be installed through the CPAN shell which you should find on your system.
% perl -MCPAN -e shell cpan> install POE cpan> install POE::Component::IRC
When CPAN is first run, it will ask you a series of questions, however the defaults seemed to work fine for me. However I did have a problem with some FTP sites not having the POE file, so I went for ones in the US and they had it.
You may find that POE fails to install with a message that says cannot install unless force is used as a number of tests have failed. You might want to check the seriousness of these errors, however its possible to force via the following syntax.
cpan> force install POE cpan> install POE::Component::IRC
LocalSettings.php
[edit]Add the following to your local settings file:
// IRC port #: 51666
$wgRCFeeds['irc'] = array(
'formatter' => 'IRCColourfulRCFeedFormatter',
'uri' => 'udp://localhost:51666',
'add_interwiki_prefix' => false,
'omit_bots' => true,
);

Command
[edit]Run this command on the receiving computer:
./WikiBot.pl
Caveats
[edit]Currently, anyone can "hack" your bot by sending packets to the port you specify. This can be fixed with iptables.
However, in the long run, a more complex bot should be written to allow for restrictions and perhaps some more stuff.
