Logging IRC
Google searches a lot, but so far they wont touch IRC, the Internet Relay Chat network*. Here, people meet and talk all day long, and of course, they produce a lot of content doing so. But how do you track whats important to you in that content?
*Though a while ago, there were rumors of a Google spider crawling chat channels, no Google tool has surfaced yet. If nothing else there may be huge privacy issues.
Over at CodeDemons.net a tutorial shows you how to build an IRC bot, and how it can also be used to log whats being said while youre away. I modified the file and was surprised how easy it is to log IRC.
If you installed PHP you can download my modified PHP script:
<?php
error_reporting(E_ERROR | E_PARSE);
$CONFIG = array();
$CONFIG['server'] = 'graz2.at.eu.undernet.org'; // server (i.e. irc.gamesnet.net)
$CONFIG['nick'] = 'littleboy'; // nick (i.e. demonbot)
$CONFIG['port'] = 6662; // port (standard: 6667)
$CONFIG['channel'] = '#AllNiteCafe'; // channel (i.e. #php)
$CONFIG['name'] = 'littleboy'; // bot name (i.e. demonbot)
$CONFIG['admin_pass'] = 'asus123';
$CONFIG['log_type'] = "file"; // options: none, file, mysql
$CONFIG['file_name'] = "C:\bot\log.txt"; // the name of the file to log the chat to
$SQL['server'] = "localhost";
$SQL['username'] = "root";
$SQL['password'] = "";
$SQL['database'] = "codedemons";
$SQL['table'] = "irc_logs"; // the table to log chat to
/*
mysql_connect($SQL['server'], $SQL['username'], $SQL['password'])
or die ("Could not connect to database server. ". mysql_error());

?>Change the configuration settings at the top – your bots name, the server and channel, and the log file path – and run it via the command line by entering e.g. C:\php5\php.exe C:\bot\irc.php. I suggest to join the channel yourself using a program like mIRC to check everythings working. (You can also use mIRC to find out about popular servers and chat rooms.)
Now whenever someone mentions Google or search, your log file will have a new line with what has been said. The script Ive got running on my machine logged the following in the past half hour:
[Google February 13, 2005, 6:05 pm] put "ravana" on search on google
Of course you can track any other keyword too. Search the PHP file for google and you will see the process_commands function. This function can either do a logline to add something to the log file, or execute the say command to say something in the channel.
The process_commands function can also be used to do anything else PHP (and the chat network guidelines) allows you to. You can connect to a database to perform calculations or track words. You can check the Google page-count of words said, and track rare words mentioned often (the hot topics du jour). By parsing whats being said in the channel, your bot can also join the conversation and react to other people. A bot type popular in some channels, for example, listens to the google command and will dynamically execute a Google search and return the result in the channel for everyone to click on.
