Games-Tournament-Swiss Version 0.11 I wasn't happy with 0.10 and there's a major change in the C10 code, so I'm putting this out quickly. If you thought that the pairings you were getting were correct, you were mistaken, or your pairing table wasn't generating any unpairable remainder groups! Warning! This is ALPHA-level software. Although it attempts to implement the FIDE Swiss Rules, it may not pair players correctly. It may take over your computer, and force you to reboot. It may DELETE files. It may DESTROY your computer. Use at your own risk. NOTICE: More tests are needed. If you have an interesting pairing table that is difficult to pair, please report it as a bug at http://search.cpan.org/~drbean/Games-Tournament-Swiss/. The code to pair players applying relative criteria should now be better, but only one or two tests test it. So try to break Games::Tournament::Swiss and report your results! This is a minor/major revision. I am feeling I am getting a grip. The code is 'talking back.' Working with the brackets' hash-based indexing is interesting. Life is good. I didn't get any cpan tester failures with 0.09, the broken version. I'm getting more with 0.10, which I also thought was broken. I wonder what will happen with 0.11. I recommend looking at the scripts. If you want some more help, look at the tests. Again, scripts are still likely to break, but the purpose of that is to get you to write your own scripts. (ha-ha) Look at the scripts and the tests. This program is run from a shell. You need to work from a command line and type commands. It also depends on perl to run. If you don't know anything about perl, you will have to learn something about installing it and running scripts, before you can use this software. For perl on Windows, try the free download of ActiveState's distribution at http://www.activestate.com/store/activeperl, or the experimental Strawberry Perl http://win32.perl.org/wiki/index.php?title=Strawberry_Perl On other platforms, find it from your regular source for new packages. INSTALLATION This software doesn't install itself. To install this module, run the following commands: perl Build.PL or perl Makefile.PL ./Build make ./Build test make install ./Build install make may be nmake or dmake on Windows. The tests will take a few minutes. The distribution is made up of modules and scripts. The modules provide functionality that you can use to write your own tournament software. The scripts are an example of a swiss pairing program. SCRIPTS The scripts in script_files/ need to be installed somewhere so that they can be run in the directory in which pairing of each round is done. DIRECTORY LAYOUT The scripts assume that there is a directory in which a configuration file, called league.yaml, with data about the players exists. The rounds are paired in subdirectories, named 1,2,3,.. below this directory. Files named: brackets.yaml pairing.yaml round.yaml matches.yaml player.yaml tourney.yaml are left in these subdirectories after pairing. Scores are in another subdirectory called scores. They are of the form 1.yaml, 2.yaml,.. You need to create these files, if you use 'pairstately'. You can create a pairing table with 'pairingtable,' convert it into YAML form with 'pairtable2yaml' and run 'pair.' DATA FILES Do not use tabs in these YAML files. The level of indentation is significant. Follow the examples closely. The first, league.yaml has lines of the form: member: - id: 1 name: Laver, Rod rating: 2810 title: Grandmaster - id: 2 name: Sampras, Pete rating: 2800 title: Unknown - id: 3 name: McEnroe, John rating: 2780 title: Unknown If you are using your own scoring scheme, and colors (called, roles), see the example below. You can add your own data to the member records. A pairing number is generated for the players, so don't add a pairing number. TODO Configuration of your own scoring scheme looks like it is broken. The score files: 1.yaml, etc, are of the form: 'Laver, Rod': Loss 'Sampras, Pete': Win 'McEnroe, John': Bye First number is the name of the player. (Every name will have to be unique.) The second is the result for that player. Alternatively, 1: - 'Laver, Rod': 0 - 'Sampras, Pete': 1 2: - 'McEnroe, John': - A sample scoring scheme, abbreviations and roles in league.yaml could be: scores: win: 1 loss: 0.5 draw: 0.75 absent: 0 bye: 1 abbreviation: W: White 1: Win '=': Draw roles: - White - Black For the form of the pairing table and its YAML equivalent, see the documentation for 'pairtable2yaml.' GENERATING PAIRINGS Starting with an empty main directory, create league.yaml, and an empty subdirectory for the first round. Run the script, 'pair' in the empty round subdirectory. A log of the pairing is printed and 'round.yaml' in the directory contains the matches. After the games in the round are complete, in the scores subdirectory, enter the scores for the players in the file, '1.yaml', or whatever the round is. Then you can run 'crosstable 1' or 'pairingtable 1' in the original directory above the subdirectory, to get current standings. Convert your pairing table into YAML form with 'pairtable2yaml' and copy it into a subdirectory for the next round, and continue as before.
