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:

• parse PGN's pgn/2
• store the parsed terms into prosqlite databases chess_db/2
• manipulate the resulting databases chess_db_opening_pgn/2

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

Dependencies

These are all stoics packs available from SWI-Prolog pack installer:

• lib (2.11)
• prosqlite (1.5)
• db_facts (0.5)
• debug_call (2.1)
• options (1.0)
• stoics_lib (1.0)

Pack lib, is the only dependency installed with chess_db. The rest will be installed on first run (code in pack(lib)).

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
