This library produces chess games databases from PGN files and provides some
predicates for manipulating these databases.

Once connected to a number of chess_db databases, all kinds of information about the games
can be interrogated. (see chess_db_opening/2 for an example).

Ideally we want to hook this pack to a web-page interface for playing the games as we select them.

Installation:

?- pack_install( chess_db ).

The pack includes code to:

There are two example databases in data/ and an example program, examples/short.pl

Dependencies

Packs:

prosqlite
(1.5)
db_facts
(0.5)
stoics_lib
(1.0)
options
(1.0)

Basics

By default, chess database dirs contain 3 sqlite databases:

game_info.sqlite
contains game_info(Gid,Key,Val) info about each game
game_move.sqlite
table is of form game_move(Gid,Num,Turn,Move)
game_orig.sqlite
table is game_orig(Gid,Orig); where Orig is the verbatim of the section in the PGN for that game

A number of databases can be connected at the same time.

For example a number of databases can be declared in dir/1 terms within file:
~/.pl/chess_db_connect.pl see options_append/3.

Example

== ?- [pack('chess_db/examples/short.pl')]. ?- short. % creates a chess_db in subdirectory short/ from data/4ncl_short.pgn % and displays the game ids for games that start with [e4,e6] (French defence) ...

?- french. % creates a new pgn file from the base for the 2 games in short/ that start with e4,e6 % Handles already exist, for chess_db directory: '/home/nicos/pl/packs/src/chess_db/examples/short' gid(chdbs(<sqlite>(0x71b4f0),<sqlite>(0xe577f0),<sqlite>(0xe13400)):1) gid(chdbs(<sqlite>(0x71b4f0),<sqlite>(0xe577f0),<sqlite>(0xe13400)):31) writting_to_file(short/french.pgn) true.

% open file french.pgn on program that can play the games
