* 2.0
Write chess-game-to-pgn and chess-pgn-to-game.
Get keyboard shortcuts working, right now "nf, nf", causes an error.
* Other
- Clipboard copy and paste should be global, and occur in this module
- Port image display code to XEmacs
- Keep a history of boards, and the moves corresponding with them, so
that the move history can be stepped through forward and back.
- Allow the user to retract a move when playing against crafty.
- Tie-in to ics.el, by adding "Internet opponent" to the opponents
list.
- The ability to read and playback existing PGN files.
- A way to set the time control, and display its status.
- After a castle, the rook might place the opponent's king in check.
This is not considered at the moment.
- After piece promotion, change the piece accordingly and look for
check posibilities (it's done with the pawn at the moment, which is
useless).
- Handle en passant.
- Support chess by mail, with direct tie-ins to Gnus/RMAIL.
- Allow the opponent to give hints.
- Choose the default image set based on the screen size.
- Find some prettier image sets.
- If the chess computer croaks, handle it gracefully.
- A better way to visually show who's turn it is now?
- The source have some strings with non-ascii content.
- In a PGN file, offer the commands: chess-continue, chess-replay,
chess-show-position (which works for whichever sequence the cursor
is in).
- For modified boards, add a command key to say that it's really black
to play, not white (or vice versa).
- Multiple game buffer selection is a bit screwy. M-1 M-x chess will
not select the first buffer, for example. Perhaps named games would
be better?
- Add a command that will load a saved game, continue it, and then
enter a move for whichever color is next to play. This would make
it trivial to add chess drivers to AIM, IRC, etc. The mere command
"!chess johnw37 Nf3" would mean: load the chess game johnw37, and
make my move as Nf3. It would also make chess by e-mail a snap to
implement.
- Modify etalk's chess.el to use this chess.el as its library.
- Add an analyze command that will indicate which pieces are defended,
how well, which are attacked, which moves would increase
defense/attack/both, etc. Basically, everything that can be known
about the current board, and one move ahead (on both sides).
- Add a warning mode that will use the results of an analysis to warn
the user (and ask for confirmation) before doing something that
might lead to an inferior position.
- Create chess-player.el, which creates persistent objects that
encapsulate information about any player: where he is, his name, his
opponent type, etc. This would maintain a log of games against that
player, their current chess rating, etc. Then, M-x chess would ask
you for a player, not an opponent.
- When editing the board in display mode (or doing speculative moves),
doing them on a copy of the board with no hook except the display
hook. Then, if you like the result, it call be a `set' on the
original board from the copied board.
- If moving your opponent's piece is bad, why let you select it in the
first place? Also, don't let them select a blank square.
- Allow a networked mode that uses the X display protocol to show the
same board on two machines. That way, the guest machine wouldn't
even need to be running Emacs!
- Once this is in place, one could play games without a log by just
sending the board config and move, back and forth.
- Add a Map command, that will colorize the squares depending on
whether they are reachable by either side. Green if reachable by
you, Red if by your opponent, and blue if by both. With a prefix
argument, colorize only the squares that have pieces on them. This
is a stable modes that remains in effect until turned off. It also
requires the ability to pass a color to the chessboard highlighting
routine.
- If a person selects a piece with the mouse, then uses right-click to
designate a target square, display the resulting board without
making a move. This requires copying chessboard-current-board to
chessboard-draft-board. If the user right-clicks without selecting
a piece, it will reset to chessboard-current-board and redraw.
- Using display-pixel-width, and the images known to be available,
find the largest piece size that will fit.
- Break out the display code into its own set of modules, then
parameterize the call into them so that alter size and change
directory uses them. Right now those two functions are hard-coded
for image displays.
