 182   Maybe pgn-mode could just allow normal editing, and bind some keys
 183   to do special things. e.g., the mouse binding could work as normal,
 184   SPC could update the display. So if you do
 185
 186   1 e4 SPC
 187
 188   you get the move displayed. Some binding could do redisplay anyway, e.g. C-l?
 189   Then, one could enter variations or such simply with ( or { and
 190   the display would update automatically.
 191   e.g., you do
 192
 193   ( 15.e5 SPC Nf3 SPC )
 194
 195   and you'd get three display updates, on e5 SPC, you get that
 196   ply, then the second one, and on ) you get the position before the
 197   variation. Move point into the variation again, and hit C-l and you
 198   get the pos where point is on.
 199
 200   There should be a forward-ply and backward-ply, maybe something like
 201   M-f / M-b, and C-u M-f for two plies forward?
 202
 203   Very nice would be a pcomplete-based completion fascility, so
 204   simply hit TAB at any point, and you get the right completion.
 205
 206   Example:
 207
 208   [Event ...]
 209
 210   TAB 1.TAB ...
 211
 212   On first tab, the move number is inserted. On second, you get
 213   all possible moves in that position.

 275   Well, I've played a little with a few transformations but I haven't managed

 277
 278   - char-valid-p is called at least three times, the value could be saved in
 279     the toplevel let*.
 280   - I am not sure but I think I read inline quoted lists can be slower.  I
 281     tried to define the direction lists as a alist in a defconst, but it
 282     didnt't really show as a speedup...
 283   - The chess--add-candidates defsubst does needless check of check-only in
 284     some cases.  I.e., if we rewrite the first cond clause to do different
 285     things if check-only is t or nil, that might also do a bit.
 286
 287   But really, I didnt find anything worthwhile... Maybe it could make sense to
 288   have a separate function to handle the (memq piece '(nil t)) case.

 403   (NOTE: this might proof problematic since descriptive move notation is

 406   to use a game object as reference, rather than just a position.)

 452     I believe I have a fix for this, commit
 453     33d57dc0f667c8d1168b46f9e73d9510d8c7e518, but I must await Mario's test on his
 454     8 CPU machine.
 455   It happens on a fast 8-CPU machine of mine that chess-scid-get-result
 456   returns the empty string.  The reason for this is that sometimes, the prompt
 457   is not output immediately after a result, so upon next call to
 458   chess-scid-get-result the first output we see is the prompt ("% ") from the
 459   previous command which due to the current algo results in
 460   chess-scid-get-result returning "".  It would need to continue reading if it
 461   sees a prompt as first output.  Waiting until we see a prompt to make sure
 462   we have all the output results in *very slow* behaviour, maybe due to
 463   line-buffering (the prompt has no final \n, obviously), so we probably shoud
 464   skip over prompt and continue reading.

 477     Fixed.  This appears to be a bug in looking-at/match-string, but it only
 478     occurs under high load and certain circumstances.  I was able to get around it
 479     by examining the buffer directly.
