Tonic Chess project is an online chess software.

Tonic is a graphical interface for playing online chess. It is based on Jin.

From now on Tonic is really open source software (and free as in libre as well) - I managed (I had some problems last time I tried) to import source to cvs sourceforge repository. It is a bridge2 release source with few little modifications. You can read how to get it from cvs here. If you are impatient pastenenter in console:

cvs -d:pserver:anonymous@tonic-chess.cvs.sourceforge.net:/cvsroot/tonic-chess login

When prompted for password just hit enter. And then:

cvs -z3 -d:pserver:anonymous@tonic-chess.cvs.sourceforge.net:/cvsroot/tonic-chess co -P tonic

You should see a list of files downloaded from cvs repository. If you are a non-console user (i.e. Windows or Mac user) I recommend visiting this site. I myself use Linux for development. And Netbeans sometimes as you could figure out from examining the contents of tonic directory. So, enjoy the opensourceness of Tonic!

I uploaded new screenshot to Tonic project site. It is Tonic in Aero GTK engine tuxedo. Quite a peculiar engine imo, but you can use other GTK engines if you run Tonic in Java 6 aka Mustang (you know you can get it from here, dont you?) I test Tonic with Mustang and Ive problems with tray icon. After some searching Ive realized why Tonic crashed under Java 6 - the problem was tray.jar plugin and its dependencies - tray.so or tray.dll, so if you want to run Tonic on Java 6 move them away from theirs directory. Ive written a class for tray icon using new desktop API from Mustang, but it doesnt work as expected in KDE (tray icon is invisible) ; GNOME is better, but I have to work on the popup menu. Well, what could I say? Mustang is in beta stage, but it has some goodies to wait for (early splashscreen, access to tab component, ...).

Chess::FIDE is a Perl extension for FIDE Rating List.

SYNOPSIS

use Chess::FIDE;
my $fide = Chess::FIDE->new(-file=>filename);
$fide->fideSearch("surname eq Kasparov");

Chess::FIDE - Perl extension for FIDE Rating List. FIDE is the International Chess Federation that every quarter of the year releases a list of its rated members. The list contains about fifty thousand entries. This module is designed to parse its contents and to search across it using perl expressions. A sample list from April 2004 is provided under filename APR04FRL.TXT The following methods are available:

Constructor

$fide = new Chess::FIDE(-file=>localfile); $fide = new Chess::FIDE(-www=>1,[-proxy=>proxyaddress]);

There are two types of constructors - one takes a local file and another one retrieves the up-to-date zip file from the FIDE site, unzips it on the fly and parses the output immediately. In case of the second constructor no files are created. Also usage of an optional proxy is possible in the second case.

Each player entry in the file is scanned against a regexp and then there is a post-parsing as well which is implemented in function parseLine. The entry is then stored in an object defined by the module Chess::FIDE::Player (see its documentation). Every new object is inserted as a hash member where the FIDE ID of the player is the key. A sparse array could be used instead, though.

fideSearch

@result = $fide->fideSearch("perl conditional");
Example: @result = $fide->fideSearch("surname eq Kasparov");

Searches the fide object for entries satisfying the conditional specified as the argument. The conditional MUST be a PERL expression within double quotes. All constant strings should be expressed within single quotes because the conditional is evaled against each entry. Any conditional including a regexp match that may be eval-ed is valid. For the fields to use in conditionals see Chess::FIDE::Player documentation.

IRC-Chess project is a 2-player chess game for IRC which turns a computer into an IRC chess bot.

It consists of a Java chess server, with frontend scripts to convert an IRC client into a chess bot. Players then communicate with the bot using standard IRC commands, and dont require any special software to play.

Frontend scripts are available for IRSSI and X-Chat.

The client is merely responsible for interpreting this data and displaying it. In this way, porting the system to a variety of IRC clients is very simple, since
the client script will be short, and effectively contain no code specific to the game being played.

In other words, the Java part is smart. The script is dumb and is just there to make things look pretty.

This idea works. Currently, client scripts have been designed for RSSI and XChat. Since both these programs use Perl for scripting, the scripts are practically identical, with a few client specific modifications.

Porting this script to other IRC clients shouldnt be too much of a hassle, since its just the frontend thats ported, not the chess game itself. Anyone wanting to create frontend scripts for other IRC clients, please feel free to do so.

The PROTOCOL file describes exactly what needs to be done.
