Project description
pgn-filter
A small program to query for games inside PGN documents.
You can supply basic queries using command line arguments and you can write more advanced queries using python scripts.
Example queries
Games starting with d4
from chess import Move
def query(game):
first_move = list(game.mainline_moves())
if first_move[0] == Move.from_uci("d2d4"):
return True
return False
Games with no castling moves
from chess import Board
def query(game):
board = Board()
for move in game.mainline_moves():
if board.is_castling(move):
return False
return True
