2013-09-05Load `cl' at compile time for `assert'.Mario Lang
2008-09-02Implemented a safer method for parsing algebraic moves, since for some reasonJohn Wiegley
we weren't always seeing the full move when using looking-at. The way I do it now is to require some kind of whitespace after the SAN move text.

unspecified promotion.

2004-01-25Added an argument to chess-search-position, so that if we areJohn Wiegley
searching for the source of an algebraic move, and it is not a castle, then do not check castle moves.
2004-01-14`let'-bind case-fold-search nil in chess-algebraic-to-ply:Mario Lang
This fixes a bug where b8c6 is parsed to c7-c6.

2002-05-01Tiny code rearrangement. If chess-ply-castling-changes fails, no plyJohn Wiegley
create will be attempted.

2002-04-17More general bug fixing, efficiency improvements, etc.John Wiegley
2002-04-16Removed the $ Revision strings; they are no longer necessary since IJohn Wiegley
tag every revision that I upload.
2002-04-16Major speed improvement and efficiency work. chess-legal-plies isJohn Wiegley
much more memory conservative now. Reduced recursion in chess-search-position by a slight bit.
2002-04-16Keep the :which determiner, if ever we calculate it inJohn Wiegley
chess-ply-to-algebraic.

2002-04-08added castling keywordsJohn Wiegley
2002-04-08Simplified the code, removed the 'search-function' nonsense. Even theJohn Wiegley
wackiest chess variants use standard move notation. `chess-ply-create' now fully validates and annotates the plies that it creates, based on the initial piece move (such as the king, in the case of castling).
2002-04-07Simplified the event model, and removed session objects. NowJohn Wiegley
everything just revolves around a game. Gnuchess is now playable to the end, except don't make moves that leave your king in check! The engine still doesn't check for this yet.
