added support for highlighting legal plies
[gnu-emacs-elpa] / TODO
1 Aha! I knew there had to be a way. The old keyboard shortcutting
2 code (which uses chess-legal-plies) was just way to slow. On modern
3 machines you couldn't notice it, but on my 300 MHz laptop in battery
4 save mode, even with the byte-compiled files, I spent 1/4 of my time
5 looking at the hourglass cursor. So I kept chewing on the algorithm,
6 dropping the number of calls to chess-search-position (the biggest and
7 slowest function in all of chess.el) from 5400 calls down to 4300
8 calls. But still it was slow. Then I thought about it long and hard,
9 and realized chess-legal-plies was going about its whole job
10 backwards. Since that function is only used by keyboard shortcutting,
11 I found a way to optimize it for that task, while keeping it as
12 general as before (by adding a "piece-or-color" argument). The net
13 result is that I got the number of calls to chess-search-position down
14 to 797!! That's 5000 calls less. It dropped the number of uses of
15 `chess-incr-index' by 20,000. The new code is so fast I that when
16 it's byte-compiled, I never see an hourglass cursor, even on my
17 laptop.

19 - Feature work remaining:
20
21 annotations
22 chatting
23 clocks
24 bughouse/crazyhouse
25 analysis/highlight tools
26 database interaction (chess-file.el, chess-scid.el)
27
28 ----------------------------------------------------------------------
29
30 - undo is not working with gnuchess
31
32
33 - test making an en passant capture
34
35
36 - the game should go inactive once I lose by stalemate/checkmate
37
38 - detect draw/resign/abort/retract, etc., from ICS and common engines
39
40
41 - in chess-ply-create signal an error on invalid plies describing why
42
43 - for network transports, if an illegal move is encountered, report
44 this with "illegal move: REASON"
45
46
47 - incorporate the .wav files from xchat's sounds that chess-sound
48 currently doesn't have
49
50
51 - devise a better scheme for printing messages (use a catalog?) and
52 for when engines need to ask questions
53
54 - there needs to be much more robustness; it's too easy to get the
55 game into an unplayable state right now
56
57 - in chess-engine-filter and chess-ics-filter, if an error is
58 encountered, skip that line so the same error isn't triggered again
59
60 - in chess-ics use a server-alist, and make the default handle be
61 "guest". Allow a password to be specified, or a filename containing
62 the password
63
64 (HOST [PORT HANDLE PASSWORD HELPER HELPER-ARGS...])
65
66 ----------------------------------------------------------------------
67
68 - Add support for adjournments; also, implement this is such a way
69 that an e-mail or postal game is basically a game that's adjourned
70 after every move
71
72 - Break my dependency on cl
73
74 - Use more asserts throughout the code
75
76 - Read-only mode needs to be a bit more vigorous. There's nothing
77 preventing the user from using M-x commands.
78
79 - Add an engine function for obtaining an evaluation of the current
80 position. Then, allow M-x chess to startup a non-game oriented
81 engine, solely for the purpose of submitting position evaluations,
82 and displaying the result in the modeline. (Also, look at crafty's
83 kibitzing feature).
84
85 - Complete chess-pgn-mode
86
87 - Write a chess-database.el interface, and then add chess-lisp.el,
88 chess-file.el (PGN games in a flat file) and chess-scid.el
89
90 - Use MIME attachments (application/x-chess-pgn) for sending e-mail
91 chess games back and forth. Add code for special MIME handling of
92 this type in Gnus.
93
94 - Copy some of ics.el's nicer functionality into chess-ics.el
95
96 - Add support for ICS observing
97
98 - Make the mode-line much more informative, with information on who is
99 playing, etc.
100
101 - Turn on memory gc collection messages, and see how much of a pig
102 chess.el is
103
104 - Make as much of chess-game/ply/pos, etc., defsubst as possible.
105
106 - Create a series of generic functions and predicates, so that users
107 can say (chess-position OBJECT) or (chess-move OBJECT), without
108 needing to know the type of OBJECT.
109
110 - Change chess-display-set-... to chess-display-set, and make it use
111 the new generic functions.
112
113 - Use server-side sockets in chess-network, if Emacs supports it
114
115 - Support auto-saving of games to PGN, and saving them at appropriate
116 points; this will require database interaction support
117
118 - Allow ASCII displays to use a separate frame
119
120 - In edit mode, mouse-2 and mouse-3 should provide a drop-down list of
121 pieces the square can be set to. Cursor movement is really not the
122 best for chess-images. I still need to figure out how best to
123 handle cursor-type with that display.
124
125 - Still need to test many areas: position editing
126
127 - Implement engine options; then, in chess-puzzle set the option that
128 tells the engine not to resign.
129
130 - Add a display command for writing out the currently displayed game
131 to a file. It will use PGN for games, and FEN for positions.
132
133 - Remote displays are horribly insecure.
134
135 - When editing the board in display mode (or doing speculative moves),
136 doing them on a copy of the board with no hook except the display
137 hook. Then, if you like the result, it call be a `set' on the
138 original board from the copied board.
139
140 - Resize the chess board on a window resize event, if possible.
141
142 - Add chess-game-strip-annotations, for removing all annotations from
143 a game object
144
145 - Add a module for chatting between opponents
146
147 - Let the user specify a default size for the chess-images display
148
149 - Need to check for chess engine resignations
150
151 - Need a chess-clock.el module, especially for playing on ICS
152
153 - Port image display code to XEmacs
154
155 - Support chess by mail, with direct tie-ins to Gnus/RMAIL.
156
157 - Allow the opponent to give hints.
158
159 - Add a command that will load a saved game, continue it, and then
160 enter a move for whichever color is next to play. This would make
161 it trivial to add chess drivers to AIM, IRC, etc. The mere command
162 "!chess johnw37 Nf3" would mean: load the chess game johnw37, and
163 make my move as Nf3. It would also make chess by e-mail a snap to
164 implement.
165
166 - Add an analyze command that will indicate which pieces are defended,
167 how well, which are attacked, which moves would increase
168 defense/attack/both, etc. Basically, everything that can be known
169 about the current board, and one move ahead (on both sides).
170
171 - Add a warning mode that will use the results of an analysis to warn
172 the user (and ask for confirmation) before doing something that
173 might lead to an inferior position.
174
175 - Create chess-player.el, which creates persistent objects that
176 encapsulate information about any player: where he is, his name, his
177 opponent type, etc. This would maintain a log of games against that
178 player, their current chess rating, etc. Then, M-x chess would ask
179 you for a player, not an opponent.
180
181 - Add a Map command, that will colorize the squares depending on
182 whether they are reachable by either side. Green if reachable by
183 you, Red if by your opponent, and blue if by both. With a prefix
184 argument, colorize only the squares that have pieces on them. This
185 is a stable modes that remains in effect until turned off. It also
186 requires the ability to pass a color to the chessboard highlighting
187 routine.
188
189 - If a person selects a piece with the mouse, then uses right-click to
190 designate a target square, display the resulting board without
191 making a move. This requires copying chessboard-current-board to
192 chessboard-draft-board. If the user right-clicks without selecting
193 a piece, it will reset to chessboard-current-board and redraw.
194
195 - Using gnuplot-mode, allow evaluation trends to be plotted
