ChangeLog for XBoard/WinBoard
-----------------------------

(latest entries created by git log --no-merges --pretty="%ai %an <%ae>:%n%s%n%n%b" vlast.. )


2011-08-22 22:09:19 -0700 Arun Persaud <arun@nubati.net>:
malloc.h is not needed

2011-08-20 22:21:40 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix ICS move-list header mistaken for null moves

2011-08-18 18:53:09 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow two-games-per-opening to work with book

A new option -seedBase is added, and written to the tourney file.
It allows all XBoard instances working on a tourney to generate the same
'random' openings in a deterministic way, based on this one-time seed
and the game number. When -loadGameIndex equals -2, it uses the same seed
for an odd and the following even game.

2011-08-18 18:51:56 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix use of random

In some places rand() was called explicitly, rather than through the
(configured) place-holder random().

2011-08-18 17:34:33 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Translate search texts


2011-08-18 10:29:35 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add -useBoardTexture and -usePieceFont options

These options suppress the use of the given texture files or piece fonts
without relying on the kludge to disable them by prefixing an asterisk
to the file or font name. Checkboxes have been added to the Board dialog
to control them. The user can now set piece font in WB font dialog.
The sample text can be used to specify the -fontPieceToCharTable,
the font name itself the -renderPiecesWithFont value.

2011-08-16 23:10:59 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix crash on start without settings file

A primordial -1 in currCurrent caused a crash when WinBoard was started
without ini filein game-viewer mode.

2011-08-12 12:08:18 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix generic-popup failure after empty engine-settings dialog

The error exit ofthe Engine #N Settings dialog in case of an engine without
options forgot to clear currentCps, with as a result that the generic popup
thought every subsequent popup was an empty one, and kept repeating the
'engine has no options' error message for every dialog.

2011-08-10 11:27:22 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow substitution of engines during tournament

Two buttons are added in the tournament options dialog, for upgrading
and for replacing a tourney participant. Lots of tests on the validity
of the request are done, and if all are passed, the tourney file is
written with the new participants (and in case of replace) with the
results of the replaced engines erased from the -results string.

2011-08-08 11:00:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix up/down arrows in game list


2011-08-08 10:31:24 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add key bindings for loading next/previous game of list

These bindings are set both for the game list and the board window.
To make them useful, focus has to be transferred to the board widget
after loading (it tends to transfer to the tags window), which now
seems to work, but not always. From the game list the shellWidget
seems to get focus rather than the board, which is bad as it is not
sensitive to the key bindings.

2011-08-08 09:58:31 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow deletion of last book move

The book-edit function refused to delete the entiremove list,
for no good reason. This limitation now has been lifted.
Also the error message that the key for the current book entries
is different from that of the currentposition has been suppressed
if there were no entries found for the current position (so that the
book is positioned at the next key), so that it is possible to add
moves from scratch.

2011-08-08 00:19:53 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Speed up parser

Line numbers > 1, which are common, can exit already during move parsing,
to save lots of matching on resultsand castlings.

2011-08-07 15:13:00 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix missing files in file browser

The file browser was throwing away the first two files, assuming
they were "." and "..". Alas, this is no longer true on every Linux.
Now we actuallyc compare for these names, before skipping them.

2011-08-06 11:57:59 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Delay file loading to allow expose event first


2011-08-06 09:29:22 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix paging


2011-08-05 22:39:41 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Better fix of crash on empty game list

An empty list is now replaced by a list containig a simple message.

2011-08-05 20:31:44 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add plain arrows as key binding for stepping forward/backward


2011-08-05 20:30:03 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Debug position selection


2011-08-04 13:22:55 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Print progress during load / selection of game

The title bar of themain window is used to display a running count
of the number of games loaded / searched.

2011-08-04 12:44:45 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Parse PGN tags without allocating memory

In WinBoard malloc/free did not seem to work when preparing the game list,
leading to a huge memory list when ParsePGNTag was used. The added code
parses the required tags in an alternative way as a work-around.

2011-08-02 22:58:34 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Implement searching games in Game List for a position

For this it was needed to reconstruct all positions of the games
without loading them, so they could be compared to the currently
displayed position. A new routine GameContainsPosition is made for that.
 In Disambiguate, when the global quickFlag is set, we now do the
disambiguation ignoring check,and only if this leads to an ambiguous
move, we repeat it taking check into account to see if that resolves
the ambiguity. This causes us to miss if unambiguous moves are illegal
because they put their King in check, but who cares?
 We now do not make game-list line when not needed. If we do not filter
by text, but by position, there is no need for preparing the game-list
line for games that are not selected. All for efficiency.

2011-07-28 20:47:35 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow entry of variations in PlayFromGameFile mode

Adding variations is more like editing a comment,and not really editing
the game. Therefore we allow it on loaded games. As soon as we are in a
variation, we temporarily switch to a (hidden) EditGame mode, restoring
the original mode when we revert to the main line.
  We now also stay in PlayFromGameFile mode after loading a game,
And opening variation (fromtheComment window) in PlayFromGameFile mode
is also allowed.

2011-07-27 18:47:45 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Force Move History refresh after loading/reverting variation

The Move History window was not refreshed after switching to or from
a variation if that variation happened to have the same length as
the main line. Now a change in storedGames since the previous refresh will
force a full refresh to avoid this. For this to work, storedGames
did have to be decremented after ToNrEvent in PopInner, because ToNrEvent
calls HistorySet before the history is restored, so we don't want
it to snatch away the full refresh. A call to HistorySet had to be
added after PopInner is done restoring the move history.

2011-07-27 17:45:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Popdown Comment window on new game

What is in this window cannot possibly remain valid, and can even be harmful.

2011-01-19 11:46:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow null move in analysis and edit-game mode

In some games it is allowed to pass your turn. The internal
representation picked for such a null move is the drop of an empty
square, (EmptySquare,DROP_RANK,0,0). Computer-algebraic form is "@@@@",
SAN form is "--", (for compatibility with ChessBase / SCID), and the
non-compliant forms "null", "pass"and "Z0" are recognized in
the parser as well. ApplyMove() has to test for this special case
(to not actually clear a1), and a way to enter the pass for the user had
to be found (clicking the opponent clock, like in EditPosition mode).
 The null move is made move irreversible to prevent repetition draws
spanning null moves being adjudicated.
  Such entry of null move is now allowed in AnalyzeMode and EditGame mode.
Because Chess engines will not accept null moves, SendMoveToProgram had
to be adapted to send not the move, but the position after it in
case of a null move. This erases the move history in the engine,
so it will not react to 'undo' for that null move, so BackwardInner
had to be adapted to test for intervening null moves, and if one is
found, approach the target from the other side after loading the
earliest position before it not crossing another null move, and
then loading the moves upto the target.
  XBoard clock clicks had to be fixed, to pay attention to the shift key.

2011-07-25 21:58:58 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Give WinBoard Game List its own font

The font fort he Game List used to be shared with the Engine Output and
Move History windows, but this made it impossible to use a figurine font
in the latter two (which displays piece symbols for capitals) without
messing up the Game List. An option -gameListFont has been added to specify
the font for the Game List(and save it in the settings file), while a
control for it is added in the fonts dialog.

2011-07-21 19:02:01 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix crash on OK after Save Changes in Tags and Comment popup.

The global variables tagsText and commentText were used to pass
a string obtained from a widget (and thus not malloc'ed), which
caused a crash when the GenericReadout tried to use those variables
for the new value. Fixed by using GenericReadout (which does malloc)
to read out the text,in stead of GetWidgetText.

2011-07-16 09:31:12 -0700 Arun Persaud <arun@nubati.net>:
Revert "fixed segfault in xengineoutput", fixed in the backend now (from HGM)

This reverts commit 33a0e73843115ff6d4eacaf963a38f2e8b20b295.

2011-07-16 14:53:14 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Suppress some XBoard warnings


2011-07-15 11:21:29 -0700 Arun Persaud <arun@nubati.net>:
fixed segfault in xengineoutput


2011-07-11 20:04:57 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Disable -showTargetSquares in ICS mode

Help like this is considered cheating on FICS, so it is disabled for
all 'classical' ICS variants. (For variants eyont Shogi we don't care.)

2011-07-10 21:20:49 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Put grab on sweep-selecting in Edit Position

A right down-click starting a sweep-selection event did not grab the
mouse events, so that an up-click outside the window would go
unnoticed, and the pointer motion stayed coupled to selecting the
piece until the next click. By returning 2 from the RightClick back-end
routine we request the grab.

2011-07-09 13:50:58 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Write more labels on score axis of eval graph

The labels for +/-1 and +/-3 are now also written, provided there is
enough space.

2011-07-09 13:28:08 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Improve Eval Graph  with -evalZoom and -evalThreshold

The score range between -1 and +1 can now be blown up by a factor
specified through -evalZoom. The threshold below which histogram bars
are no longer printed (wich used to e hard-coded 25 centi-Pawn) can now
be set through the -evalThreshold option.

2011-07-09 13:18:07 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Print reversible plies done in stead of plies to go

Printing the number of plies left to the draw-adjudication point was
confusing when the N-move rule was set to a non-standard value.
In stead we now print the number of plies since the last irreversible
move, so the user can compare it to both the engine claim point (100)
and the adjudication point he set (which might be beyond 100).

2011-07-09 13:13:49 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Let WB eval graph react ot single left-click

Unlike in XBoard, the WinBoard eval graph awatys had required double-
clicking to go the the corresponding move, while there really is no
reason for this, as it is no text edit, and single-clicks have no function
(like select).

2011-07-07 19:37:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add -scoreWhite option

This is similar to -absoluteAnalysisScores, except that it works in
all modes, and flips the score given by the engines in the engine-output
window when black is to move.

2011-07-07 19:28:04 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Print 50-move counter in Engine-Output title


2011-07-07 18:50:56 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Display score/depth in Eval Graph title

No longer print it in the comment window.

2011-07-04 11:06:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Let -sweepPromotions also work for click-click moves

A click-click promotion no longer causes auto-queening, but the down-click
on the to-square causes a Queen to stick to the mouse pointer, and then
allows the user to change it through dragging backwards before releasing it
with an up-click.
  In WinBoard this required a slight change in DragPieceBegin, because
the dragged piece there only was made visible when the mouse pointer
actually started moving (and dragInfo.pos was set), presumably under the
assumption that before mouse move the piece was already on the clicked
square. Which in the case of a to-square was of course not true. (Because
a piece jumps to the mouse pointer when the click is not centered on a
square, this gives less jittery static clicks.) So DragPieceBegin has
been given an extra argument now, to indicate whether it should attach
the piece to the mouse pointer immediately.
  To make the click-click sweepPromotions work in Shogi (for which the
drag-drop sweepPromotions could never work, because it is not clear the
piece has a posibility to promote when you pick it up), translation of
the sweep-selected piece to a Shogi promoChar had to e added.

2011-07-04 10:45:04 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Improve -showTargetSquares on click-click moves

The markers on move targets are now kept when a first click merely
selects a piece, rather than dragging it elsewhere. The second click
(by definition on the to-square) then clears the markers.

2011-07-04 11:23:05 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Let PGN parser accept lower-case piece in drop moves

The @ sign prevents amiguity with other notations anyway.

2011-07-04 12:42:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix parser.c line endings


2011-06-29 20:29:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix writing searchTime in tourneyFile

This had to be derived from the variable searchTime, which gives it
in seconds, as appData.searchTime (a string in minutes) is not reliable,
as it contains the command-line value, which might have been altered
through the time-control dialog.

2011-06-29 20:25:00 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix resetting searchTime if other TC mode is chosen (XB)

This fixes a bug in the new time-control dialog.

2011-06-29 14:32:43 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix coords display on large boards

The file indicators can now run upto 'w'. Only the lowest digit
of the rank number is printed, from a table that is valid to 22.

2011-06-29 13:53:00 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix crash on making too-long FEN

The buffer for in PositionToFEN was only 128 bytes, which was not enough
for large boards such as 19x19 Go. It is enlarged to MSG_SIZ(512) now.
There also is some approximate overflow checking added (but it is not
fool proof in case there are holdings...)

2011-06-29 13:36:26 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix drop moves on boards with more than 10 ranks

The internal encoding for rank 16 is '@', and thus ambiguous with drop
moves. They were always printed as 16, breaking drop games on large
boards. The ambiguity is now solved (for boards with more than 16 ranks)
by checking if the preceeding letter is upper case, in which case it
cannot be a fileindicator, but must be a piece, and thus a drop.

2011-06-29 13:29:38 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Don't one-click move when legality testing is off


2011-06-23 21:18:11 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Reorder controls in Engine Setings dialog WB

To get tabbing through the controls in left-to-right order, they are
now added to the template structure in that order. Also add a tabstop
to Label options, so that JAWS will read those.

2011-06-23 14:02:50 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add tab stops in WB generic popup

The WinBoard generic popup did not put tab stops on push buttons,
including the OK and cancel button, with as a consequence that these were
skipped when tabbing through the dialog controls. In addition the tabbing
could not begin before the user selected one of the controls with the mouse.
  Now all buttons have tab stops, and the cancel button is given focus
when the dialog pops up.

2011-03-10 20:06:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement Grand Chess

Grand Chess requires a lot of exceptional handling similar to Superchess
and Great Shatran, because it also allows only promotion to a captured
piece. In addition it shares the enlarged promotion zone with Makruk and
Shogi, as well as the fact that promotion can be deferred. The 10-rank
board furthermore required a better generalization of double-pushes and
e.p. captures. On such a board double puhes are now allowed from 2nd and
3rd rank, e.p. capture from 5th and 4th.

2011-01-28 19:20:38 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow promotion to Pawn with legality testing off

In stead of ImpossibleMove promotionto Pawn now merely is an
IllegalMove, so it can be played with legality testing off.

2011-01-24 15:06:17 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Create some space in WB New Variant dialog


2011-06-20 23:53:49 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow double-digit rank numbers

The parser already understood double-digit numbers on input, and
CoordsToAlgebraic produced them on otput. This patch also fixes sending
of the moves to the computer, for which the moveList was used. The latter
stored 10 as ':', etc,to always get a 4-char move, the characters of which
were frequently being converted to fromY or toY by adding/subtracting ONE.
To not break that the one-character encoding of rank number is kept in
moveList, but in SendMoveToProgram, characters > '9' are converted to
double digits.

2011-06-23 11:26:48 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add Absolute Analysis Scores in Genral Options dialog XB

2011-06-19 20:30:09 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Increase efficiency of SAN generation / disambiguation

**************** Risky patch! **********************
The algorithm used for disambiguating and generating SAN was extremely
inefficient, because it generated all pseudo-legal moves from the relevant
position, and then for each of those did a check test (involving generation
of all moves of the opponent), before determining if the move matched the
(proposed or given) SAN move. While it is pointless to generate moves
with a piece that does not match (let alone checking them for legality).
And for a piece that matches, it is pointless to test legality of moves
that do not match the to-square.
  To speed up the process GenLegal and GenPseudoLegal have been equiped
with an argument that can indicate the piece type of the required move,
so they can skip generating moves with other pieces. TestLegality,
Disambiguate and CoordsToAlgebraic make use of this facility, and set also
(through global variables rFilter and fFilter) a to-square filter to be
applied in the GenLegalCallback before it tests the move for legality.
  This patch is especially tricky for Crazyhouse, where the piece indicated
in the move might not be the piece actually on the board, because the latter
is a promoted Pawn, and has to be demoted toits base type before the
comparison.

2011-06-19 16:18:15 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix compile errors WinBoard

The patch to make non-existing options non-fatal broke WinBoard. All calls
to ExitArgError from it now supply a third argument TRUE to fix it.

2011-06-19 14:28:09 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add -fSAN / -sSAN options

These options force the PV of the applicable engine to be converted to SAN.
They make use of the existing ParsePV routine, after shelfing a possible
PV (from user PV walking) to free the space after the last move.
Could be costly in terms of CPU usage.

2011-06-19 10:56:25 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Cure flicker in Move History window, fix highlighting

The highlighting of the current move in the Move List window by selecting
it did not always work, because some other windows were clearing their text
widgets by selecting the contents and killing it, thus snatching the
selection away. This has been changed to setting XtNstring to an empty
string as a method for clearing without side effects on the selection.
As a bonus the Engine Output window now also no longer has the black flicker
on clearing it.
  In addition, triggering a scroll by setting the insertion point to the
end of the text caused excessive flicker in the Move List window, apparently
clearing it and redrawing from scratch, (even if there was no scroll motion),
to the point where on my slow laptop the move history stayed entirely blank
during a rapid succession of moves. This has been combatted by using the
end-of-line action procedure (which does not seem to suffer from this) to put
the insertion point at the end, when we need to scroll to close to the end.

2011-06-18 23:48:13 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix crash on clearing new Move List window

When a new game started and a previous game had filled the Move List
window, a crash occurred because an attempt was made to undo the
highlighting of a no-longer-existing move, and then scrolling to it.

2011-06-18 20:46:57 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Use sound for ICS tells also with engine telluser popups

The telluser and tellusererror commands now can be assigned a sound.

2011-06-18 20:45:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add Score in Move List option to general options dialog XB

Now that we have a WinBoard-style Move History window, this option is
no longer a no-op in XBoard.

2011-06-17 21:05:00 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Redo Move History with generic popup in WinBoard style

The use of color and boldness to make the move list more readable
unfortunately cannot work in Xaw; reverse video by selection is used as an alternative to highlight the current move.

2011-06-17 21:19:41 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Remove stray else

Due to an erroneous else, the window parameters of Move History were
not retreived (and thus incorrectly saved) when the Engine Output was up.

2011-06-14 18:47:30 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make non-existing opton in settings file non-fatal

It is rather difficult to recover from a situaton where the settings
file contains an unknown option (e.g. because you downgraded to a
previous version that had fewer options), especially in WinBoard, where
the user settings file is in a hidden folder, and people might not be
able to find it, let alone edit it. By just skipping the line with the
offending option, rather than generating a fatal error, when reading
from a settings file, such options will be automatically purged from the
file as soon as you save settings.
  Small problem is that the user cannot be warned, as the initialization
has not progressed far enough at this point to generate error popups. In
XBoard we can at least print to the console, but in WinBoard there is no
warning at all. But the worst thing that can happen is that new options
in a settings file of a more advanced version will revert to their
defaults.

2011-06-14 18:20:37 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Change long form of -tf option to -tourneyFile

This is a more logical name, and in the WinBoard docs it was already
described as such. Also remove the -processes option, which in the
current design of the tourney manager is no longer used.

2011-06-14 18:17:08 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix default of -remoteUser

This has to be an empty string, rather than NULL, to prevent XBoard from
segfaulting when the -gateway option is used.

2011-06-14 13:32:38 +0200 H.G. Muller <h.g.muller@hccnet.nl>:

them correctly, and these optionsprovide a work-around for that.

Redo New Shuffle Game dialog with generic popup

The buttons are slightly renamed, and in stead of having an 'off'
button to clear it, shuffleOpenings now has its own checkbox, which is
ticked when a fixed or dynamic random is chosen with the buttons.

2011-06-10 11:58:17 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix type of shuffleOpenings

This was a Boolean option, and thus accessed by the args.h code as such,
while it was declared as an int (and used in backend.c as such). This
could have led to problems with different endianness.

2011-06-09 23:57:43 -0700 Tim Mann <tim@tim-mann.org>:
Internationalize the file browser.

The file browser was missed in the previous round of
internationalization and had gotten broken by setting international =
True in its widgets.  I got nothing but segfaults trying to set
international to False in the file browser widget subtree when it was
True in the main window, so I gave up and did the
internationalization.  It turned out to be pretty easy.

As a tiny bonus fix, I removed some ../'s from includes, and you can
now configure and build xboard in a subdirectory again.  This was
useful for building both --enable-nls and --disable-nls from the same
sources to compare functionality and make sure both still work.

Fix display of logos

The logo files are now sought relative to the WinBoard install
directory. Non-existing logos cause clearing of the logo, rather than
letting the logo of the prevous engine hang. Logo change is requested
explicitly from the back-end (when an engine is initialized for a new
game), rather than using the kludge in StartChileProcess. This required
a dummy UpdateLogos routine in the XBoard front-end.

Clear Engine-Output pane when initializing engine

This to prevent output from the previous game hanging there during the
next game, when the engine that is really playing is in book and
doesn't produce thinking output there.

2011-06-08 17:20:01 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix display of last move of last match game

When a game was adjudicated (e.g. because XBoard detected mate) GameEnds
would trigger an exit if it was the last game of the match, and thus
never returned, while the ShowMove was called only after return from
Adjudicate. An extra ToNrEvent is now used in GameEnd in this case to
cause ShowMove to be called before exiting. (Ugly kludge...)

2011-06-08 17:38:43 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix concurrency in Swiss tourneys

The pairing engine was consulted for the next round before all games of
the previous round were finished, if other XBoard instances were still
playing games. This caused the instances finishing early to stall
indefinitely. This is fixed by moving the Swiss pairing code to after
the syncInterval code. The normal pairing code (the call to Pairing)
must stay before it, because it determines the syncInterval. So ther is
a bit of tourneyType dependence cluttering up the code here. :-(

2011-06-08 17:27:01 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Give error popup when pairing engine fails

An invalid pairing now produces an error popup to inform the user, so he

Fix clock mode in tourney starting from -ncp mode

When a tourney started from -ncp mode, which was allowed in MatchEvent,
because the tourney loads its own engines anyway, the menu enablings and

2011-05-30 19:55:13 -0700 Tim Mann <tim@tim-mann.org>:
Fixed small bugs in several .po files, enabling these translations to be used.  They all probably need more work from the translation team. I don't speak any of these languages, but I did some spot checks either from my own knowledge or using Google Translate, and they generally look sane.

- Several files were in utf8 but needed to be marked as such (that is,
  "CHARSET" changed to "UTF-8").  Affected es.po, it.po, ru.po, vi.po,
  zh_CN.po, zh_TW.po.

- it.po was missing a \n at the end of one translation.

- ru.po had unescaped double-quote marks in one translation.

- vi.po needed to be normalized to Unicode normalization form C.  With
  this fix, more characters display correctly, though at least one is
  still missing in the X core fonts that xboard is able to use.
  See http://vietunicode.sourceforge.net/ for more about Vietnamese.

- zh_HK.po was written in big5 and then utf8-encoded on top of that,
  making it unusable.  I stripped off the spurious utf8 encoding and
  then used recode to convert the file to Unicode properly encoded as
  utf8.

Unfortunately, I wasn't able to test any of the Chinese translations,
as I haven't been able to get XCreateFontSet to work in Chinese
locales with any of the fonts I have installed, even after adding the
Ubuntu language support packages for both simplified and traditional
Chinese.  I did spot check a bunch of the translations using Google
Translate.

I've checked in a couple of tiny Perl scripts that I used to do part
of the fixups on vi.po and zh_HK.po in case we need them again.

Added "misc-fixed" as a fallback font to handle locales where adobe-helvetica does not have all the required characters.  The fixed font is ugly but does have a rather complete set of characters, while the helvetica font is missing Cyrillic characters (at least on my distro).  I haven't found a way to get a nicer font that includes Cyrillic to work with XCreateFontSet, but I don't fully understand why.  I'll try to improve things further in the future if I figure out what's all going wrong.

In the process I had to rewrite the code to insert the pixel size into
a font name (replacing a "*" in that field).  The new code is much
more general.

Fix display of international characters outside the ASCII range.

1) Set Xaw resources required for internationalization --
   *international and *fontSet.

2) Untangle the new XFontSet-aware code from the old FindFont code.
   It doesn't make any sense to apply the old (and obsolete) size
   searching code from FindFont to a font set, which contains fonts
   that are all the requested size.

3) With these changes, the -font option doesn't work at all when given
   on the command line.  The -font option actually is parsed by the Xt
   library, used to set the *font resource, and removed from argv
   before xboard can see it, so the option didn't really work properly
   with the new WinBoard-style option framework anyway.  Now that
   -font is even more broken, I changed the documented name of the
   option to -messageFont and changed args.h so the option is saved in
   ~/.xboard as -messageFont.

Allow generic dialog to ignore OK

Make engine startup failure non-fatal in WinBoard

Unlike XBoard, which forks first, the parent process WinBoard has direct
knowledge of a failure to execute the engine command, and used it to
trigger a fatal error. The code doing this has now been disabled. Only

action is taken to 'bury' the deceased engine process. Like in XBoard,
errors in writing or reading the pipes will trigger this.

Save time-control settings in tourney file

Because parsing the options and storing them in appData is not enough,
the time-control code setting the internally used parameters from the
appData info in InitBackend was made into a subroutine, and also caled
after parsing the tourney file.

Put saveGameFile in tournament dialog


2011-05-06 19:17:56 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Plug memory leak, filenames relative to installDir

String options are consistently freed now, before assigning a new value
to them through strdup. The init code now even does use strdup when
setting defaults. This is important for optionslike -lgf, which are not
saved in the settings file, and thus are usually left with their
default. When a dialog to set them then uses free, this causes a crash.
When setting the defaults uses strdup, ParseArgs can already free them.
This plugs an important memory leak, as ParseArgs in now called to parse
the tourney file before every tourney game (twice!), and the lists of
participants and results in it can be quite long.  Macros are defined in
common.h to make the code look simpler.
  Filenames entered through the generic popup are now interpreted
relative to the WinBoard installation folder, just as the saveGameFile
already was. The code handling the atter was made into a subroutine for
this.

Improve sizing of comment and tags dialogs

There seems to be a bug in Xaw for the sizing of buttons; they get
unpredicatble and weird sizes when the size is not explicitly set,
possibly stretching the initial width of a dialog to rediculous values.
Sizing back to a remembered value from the settings file then makes
buttons overlapand text edits shrink to almost nothing. To prevent that
we now define exlicit sizes for the buttons in tags and comment popups.

2011-05-07 14:23:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix PV walking in analysis mode

ParsePV assumed that the PV would always have been produced by an engin
thinking about the final position of the game (or the one before it). In
analysismode, however, the engine can be analysing positions internal to
the game, and the PV would be considered invalid. This is fixed by
cutting of the tail off the game (shelving it in variation fashion)
before starting the PV walk, and reverting afterwards.
  For this the PushTail and PopTail routines had to be split into an
'inner' part, doing the pushing and popping, and an outer part, handling
menu graying and popdowns (which is undesirable in in this application).

Lift limitation of text length in generic dialog XB

All string options should now point to allocated memory, as strdup /
free is consistently used on them. This is OK for values received from
ParseArgs, but for non-arg intermediate variables that must receive strg
values, such as in the comment and tags popups, strdup has to be used to
initialize those.

Implement Load Engine dialog in WinBoard

The Load Engine dialog is implemented for WinBoard, and is invoked by
the menu item Engine->Load, which formerly was Install 2nd. Install 1st
is renamed 'Edit Engine List'. Unlike in XBoard, the dialog has separate
fields for the engine executale and its parameters.
  The dialog is implemented by converting the Engine Settings popup into
a generic dialog generator.

The Machine Match menu item is now checkmarked, and no longer grayed

the match after the current game. To not be left with hanging
checkmarks, the checkmark is already removed duringthe last match game
(which is logically equivalent to ordinary Two Machines mode anyway).

Calculate and display tourney result


2011-05-04 18:42:13 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Implement Tournament Manager

New command-line options are added to specify the tourney: -tourneyType
(-tt), -tourneyCycles (-cy), -participants, -syncAfterRound,
-syncAfterCycle, -results, to be saved on a -tourneyFile (-tf), but
otherwise volatile. When a tourneyFile is specified during a match,
a new routine NextTourneyGame is called from NextMatchGame before every
game, to decide the pairing, and unload and redefine the engines, when
needed. The XBoard Match Options dialog can be used to set the options
and create the tournament file.
  Actual loading of new engines is done by TwoMachinesEvent, which is
now modified to also wait for the feature timeout of the first engine.
Waiting for the matchPause is now also implemented there, after waiting
for the engines (so they can be started during the pause).
  Pairings and color assignment is now all done in an absolute
(non-incremental) way, based on a new global game-number variable
nextGame, which takes over the function of matchGame in a tourney. The
latter is now used to count games between the same players, so it can be
still used to derive the load-file indexes (again in absolute fashion).
  The next game to play is already picked in GameEnd, so it can be
decided if there is a game to be scheduled, or if we can terminate.

Refactor code for loading games and positions in match

The code in NextMatchGame and MatchEvent was nearly the same,
(MatchEvent did a little more error checking, but that is never
harmful), and could be combined. In stead of determining the load index
incrementally, it is now calculated in an absolute way from the game
number, so it can be used more easily in tournament mode.

All the prototypes have been moved to selfile.h, to force uniformity.
The order of the #include files xstat.h and selfile.h had to be

prototype declaration. The event handler SFmotionList is considered
wrong type because of its third argument (XMotionEvent in stead of
XEvent), and had to be casted to (XtEventHandler) when passed to
XtAddEventHandler.

Create conversion tools for language files

A shell script "lng2po.sh" is provided, to apply the translation given
in a WinBoard .lng file to "xboard.pot", in order to generate a
"language.po" file containing translations for all strings for which
the .lng file had a translation. It makes use of a file "metascript",
which is the ed script used to turn the .lng file in an ed script to
turn the .pot into .po. For example, the command "./lng2po.sh
espa?ol.lng" will create a file "language.po", which can be renamed to
"es.po".
****************************** WARNING ********************************
  Note that the lng2po script does a "recode" that assumes the given
.lng file is encoded in latin-1. This means it canot be used without
modification for the Vietnamese and Chinese translation; you would have
to replace latin-1 by the applicable encoding first (CP1258 / BG2312 /
BIG5).

Make engine loadable during session

A "Load Engine ..." menu item is added to the Engine menu, which pops
up a dialog where one can replace the first or second engine by a new
one, without destroying the game state. Switching from -ncp to engine
mode needed activation of some menu items in SetGNUMode, and
re-enabling clockMode. It was also important that noChessProgram is
cleared before re-initializing the ChessProgramState.
  The Load-Engine dialog can select from the list of installed
engines, and also add a newly specified engine to this list. In this
case it saves the directory, hasBook, and isUCI info with the engine,
and optionally the current variant. When loading an engine with a
specified variant, it resets the game and switches to the new variant.

Fix sweep-promotions patch

Setting of the from square was moved to before OKtoStartUserMove in the
LeftClick handler, to make sure we could test the promotion possiblity
when OnlyMove() would have altered (x,y) to be no longer the from
square. But this setting of fromX, fromY hung on also if the move was
not OK, so you could effectively select opponent pieces and empty
squares. The from-square is now set back to undefined when it is not OK
to move the piece you clicked.

2011-04-14 11:56:59 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Alter treatment of moves with empty squares

In Edit Position mode one can move empty squares, and use them to
'capture' pieces as a means to clear their square. But this often leads
to unintended disappearence of pieces one wants to grab for dragging, if
a previous click had inadvertantly left an empty square selected: the
click on the piece is then seen as the to-click of a click-click move.
  This patch treats to-clicks of moves with an empty-square differently
from other to-clicks: Rather than performing the move (in this case
clearing of the to-square) on the down-click, it defers that to the
up-click, and only does it if that up-click is in the same square. This
allows the user to grab the piece on the down-click, and drag it to
another square, if that is what he wanted to do, without being disturbed
by sudden implosion of the piece he tried to grab.
  If the to-square is in the holdings, grabbing the piece is the only
action, as moves of empty squares into the holdings are forbidden anyway.

keeping track of the fact that there is such a daughter through a global
flag, and ignoring the pop-down command if there is one.

Fix startup focus of board window

When there were open auxiliary windows, these would have focus on
starting up XBoard. The XtSetKeyboardFocus call added in XBoard main()
was ineffective in curing that. It has now been replaced by a call to
XSetInputFocus, which does do the job. By giving input focus to the form
widget, rather than the board widget, XBoard will be immediately
sensitive to all key bindings.

Fix game-list highight error when filtered (WB)

When the gamelist was filtered, the game that was highlingted was the
n-th game in the list rather than the n-th game in the file, when the
latter was loaded (and n did not exceed the number of filtered games).
This is fixed now by searching for the line in the listbox that starts
with the game number n, rather than taking the n-th line.

now type moves when the board has focus, like in WinBoard. The typed
character appears as first character in the type-in box that willpop up.
Enter and Escape close the box; finishing the typing of the move enters
it. Like in WinBoard it is also possible to type a move number (to go
there) or (in Edit Position mode) a FEN.

Implement sweep selection of promotion piece

When the option -sweepPromotions is true, a click-click promotion move
will first display the default choice (usually Queen) on the promotion
square. While you have the mouse button still down, you can change the
piece by moving the mouse vertically.

When the option -pieceMenu is off, the piece menu will no longer appear
on right-clicks in Edit Position mode. In stead a Pawn of the chosen
color will appear immediately in the clicked square, and vertical
movement of the mouse with the right button down will cycle through
all other pieces defined in the pieceToCharTable of the current variant.
  Setting the side to move is acheived by clicking the correspondig
clock. Clear board can be effected by clicking the clock of the side
that already has the move.

Refinements to generic popup and color picker

*) The text part of a checkbox can now be clicked to toggle the option.
*) Typing <Enter> in single-line text edits is ignored
*) Using a spin button now sets focus to the affected text edit, with
the insert position at the end.
*) Using the sample field or an RGB button sets focus to the
corresponding text edit, with the insert position at the end.
*) The adjust buttons now work in reverse, with a D button for "darker".
*) Editing a color field causes the sample field to update to the new
color when you type <Enter>.
*) The color pickers now define a default color, which can be instated
by clicking on the sample field.
*) Fix some 64-bit pointer warnings

2011-04-05 17:05:39 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Let file browser filter on extension

A new text field is added in the file-browse dialog, to hold (space-
separated) extensions, on which the filenames are then filtered. This
field is initialized by the caller, depending on what we need the file
for, but can be changed by the user. (Directories are always displayed!)
  Changes in the extension field  become effective after typing a return
in it. Escape typed in the extension field gives focus to the filename
field, and restores the contents. Escape in the filename field cancels
the dialog, return ther OKs it. The extension filter of the browser is
initialized to the extension (if any) of the file currently in the text
edit you are browsing for.
  When re-opening the file browser from the XBoard File menu, and there
is no suggested filename, it will now start with the last succesfully
opened name as suggestion. Calling the browser with a NULL argument
for the suggested filename requests that (unlike calling with an empty
string, which will start it in the current directory). To make this
work smoothly, the filebrowser saves the last used name on entry, so it
can be restored on cancel, so that a cancelled browse session really
erases all memory of it.

Make a kind of ICS text menu in XBoard as a dialog

The dialog with buttons can be opened from the View menu. It is
configured by the option -icsMenu; a default setting for this is
included in the master settings file.
  The commands specified by the -icsMenu can now contain $name and $input
keywords, which will be replaced by the current primary selection, or
text the user types, respectively. Commands that contain $name will not
be sent when the current selection is empty. Commands that do not
contain $input will be sent to the ICS immediately; otherwise they will
be placed in the ICS Input Box, with the cursor at the point of the
$input, and input focus given to the Input Box, so the user can start
typing. When a command is prefixed by "$add " it will be appended to the
existing ICS Input Box contents, rather than replace it.
  The items now have to be separated by ";\n", and button text from
command by ';' (with optional linefeed). This allows configuring of
multi-line commands, as a single linefeed no longer has special
sigificance.

Redo ICS input box with generic popup

This box is just a single text edit, but the complexity is in the added
callbacks. These callbacks remain in xboard.c, and were altered to
access the edit through the option.handle field.

Let generic popup generate Engine Settings dialog


2011-04-02 18:36:09 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Merge SettingsPopUp into GenericPopUp

Based on currentCps the values read from the dialog are sent to the
engine, or stored into the option.target in the callback, and fetched
from the option.target in the PopUp. The currentCps is cleared in the
generic popdown of a transient dialog.

2011-03-06 10:11:06 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make generic dialog popup reentrant

To allow persistent dialogs to be implemented through the generic popup,
it must be possible to have several dialogs open at the same time, and
thus make sure the popdowns under the cacel or close-window button know
which one to pop down. To this end an array shells[] is created that
takes over the function of settingsShell, and GenericPopUp gets an extra
parameter telling it which element to use for storing the dialog shell.
This number is then also passed to the callbacks that trigger popdown.
This was a bit nasty for the CatchDeleteWindow stuff, which passes user
data to the callback as text strings.
Keep a separate up/down indicator, so that shell widgets can be kept
for persistent dialogs. Also keep a currentOption per dialog type.
  The coordinates and size of the window is read out and stored in a
WindowPlacement structure, (if one is specified for that dialog), when
the dialog is popped down. When initialized the structure is also used
to set the window parameters when the dialog is created. (The idea being
that the structure was saved in the settings file.)
  The routine MarkMenu checkmarks a given menu item, and logs it for the
given dialog type, so that a later popdown automatically unchecks is.

2011-02-25 12:14:25 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement Machine Match menu item and options dialog

An item to start a match from the menu is added, similar to what
WinBoard has. (The code is duplicated, so I guess it should be moved to
the back-end now, as MachineMatchEvent(), but it was tiny.) A dialog in
the Options menu was added with the aid of the generic popup, and allows
the user to set the load Game / Position File and Index.

2011-04-01 14:54:26 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Create General-Options dialog

The generic popup is used to implement a General-Options dialog, which
contains all Boolaen options that used to be set directly from the main
Options menu, plus a spin option for the flash count and flash rate.
The corresponing options are removed from the main Options menu, but the
whole thing is made conditional on a compiler switch OPTIONSDIALOG.
The dialog needs an OK callback for sending an altered ponder-state to
the engine. (Why isn't this option disabled in -ncp mode, btw?)
A spin control is added to adjust -animateSpeed between 5 and 100.
Add dropMenu and showTargetSquares item as well.

2011-04-01 18:16:47 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Redo new-variant dialog with generic popup

Some special code was added in GenericPopUp() to force buttons of the
type needed in the New Variant dialog (wide, colored, greyed-out on
variant type). The dialog was implemented with these, and callbacks for
the buttons directly exit the dialog, without the need for OK. New spin
controls are added to the dialog for adjusting the board format.

2011-04-01 14:48:48 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Redo common-engine dialog with generic popup

Add board dialog XBoard

The GenericPopUp() is used to implement a dialog for board options. The
board dialog needs to trigger redraw and redefinition of the
colors, through an OK callback. Color-pickers are used for the 6 basic
color settings.
  To allow changing board settings during the session (i.e. from a menu
dialog), the routines to allocate resources have to free the resources
for the previous settings first. This patch take care of XtCreateGCs(),
preventing re-creation of resources that are unchangeable (such as the
grid color), and calling XtReleastGC() on GCs that can be changed.
To prevent resource leaks the old pixmaps are deleted before making new
ones on second or later calls of CreateXPMPieces().

2011-04-03 11:39:26 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add browse button to generic popup

Options of type FileName and PathName cause a browse button to be added
behind the text field. The SpinCallback is used to handle the
button presses, and invokes the file browser dialog to obtain a
filename, which is then copied to the text field.

2011-04-01 21:49:26 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make generic XBoard popup, and implement 2 dialogs

The Engine-Settings dialog of XBoard was cloned to work on predefined
lists of (XBoard) options, rather than engine options. An extra field
was added to the Option struct, to hold a pointer to the XBoard variable
that should hold the option setting, so on OK'ing the dialog the altered
values can be copied there. Not usable for options which should trigger
an action (like redraw, or sending something to the engine).
A Load Game, Save Game and ICS Options dialog were then defined by
tables fed to GenericPopUp(). Options set from these dialogs were removed
from the main Option menu, which removes a lot of code from xboard.c
(for checkmarking, disabling the menu items).
  A button defined in the GenericPopUp can attain the color indicated
by a previous text field, and add a callback to change the color in a
spin-like manner (but using R G B W in stead of + - butons).
The EndMark option can specify a callback, to be used on OK.
A non-zero max field in the Option descriptor will be used to set the
width of ComboBox, TextBox and Button optons.
The elements are chained such that extra space goes fully into the input
fields. A label type is added for clarifying texts that would not fit in
the option names. A break-type (pseudo-)option is added. Make OK and
cancel button suppressable in generic popup (by 2 bit of the option.min
field).

2011-04-03 11:34:21 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add file-browser option to just return name

By passing mode "f" the file browser dialog will not open the selected
file at all, so it can be used to retreive the name for the benefit of a
file-browser button to a -file option. A mode "p" will limit the
selection to directories only, to browse for a path.

The non-compliant notation of castling with lower-case 'o' should be
preferred over the non-compliant interpretation of moving a Pawn along

castling! So an exception is now made for the o-file in the 'fxg'

Fix two bugs in reading position diagram

When reading a game without FEN tag, a position diagram is used to set
the initial position. This calls CharToPiece() with a '.' as argument,
because that is the position-diagram way to indicate empty squares.
altered CharToPiece() over time this would be recognized as the first
undefined piece or, more recently, the first piece without nickName,
which is a white Pawn. Now it returns EmptySquare again in that case.
A second problem was that for position diagrams in braces the brace was
not in the list of ignored characters, and would cause the reading to
get out of phase, so that the side to move was not recognized.

Fix showing of user move after adjudication

The correction of the fishy patch (removing ShowMove() from Adjudicate())
had broken the adjudication of user moves (that actually did work before
the fishy patch, because there the gobal fromX/Y and toX/Y do contain
the correct values for the move to be shown). An entered move that led
to adjudication (like a checkmate) now was not displayed at all. Adding
an extra ShowMove() after (successful) return of Adudicate() solves it.

Clean up fishy patch

None of the ShowMove() calls in Adjudicate() was working, because when
this code was taken out of HandleMachineMove() it was taken outside the
scope of the local fromX, fromY etc. there, so that it started using the
global variables from the mouse driver. As these usually contain -1,
this suppressed move animation and highlighting. All these calls have
now been removed, and ShowMove() is called after a positive return (from
HandleMachineMove(), so within the correct scope).
This improves the previous fix, which led to some flicker, because the
erroneous ShowMove() calls did draw the new board (instantly), wich in
the fishy patch was then immediately overwritten by the old position, to
start animation. This drawing of the old position is now no longer
needed either.

Greyout unavailable variants in New Variant dialog

The WB radio-button code is refactored to be driven from a list (which
must be kept in phase with the variant definitions in common.h!). It now
also checks if the first engine supports the variant, and greys out the
item if it isn't. XB now also makes this check. Slight re-ordering of
10x8 variants there, to have the more common on top.
If no radio button is selected, keep old variant even on OK.

Move clock-click code to back-end

Some duplicated (or should-be-duplicated) code for handling clicks on
the clocks from the XBoard and WinBoard front-ends was merged and
relocated to the back-end, so it can be shared. Noticeable was that
XBoard allowed turn change in ICS examine mode by clock clicking,
while WinBoard did not. WB, on the other hand, allowed clock adjustment.

Fix WB Sound Options greyout and remove some grossness

The sound and ICS Options menu items in WB were accessed 'by position',
with fixed defined positions (always messing up any reorganization of
the menus when you forgot to redefine the position constants in
winboard.h). And not only that, but for completely mysterious reasons,
the greying of the sound item greyed out the game-list options (above
it) in stead when it was defined as 9, and the ICS options (below it)
when it was 10 !!!. Now they are addressed 'by command' (and the
position definitions are removed), which fixes things.

Fix type-in of drop moves

Drop moves entered through the move type-in already come in the (piece,
DROP_RANK, x, y) format, rather than having a holdings from square. This
caused UserMoveEvent to consider them illegal when testing if the
piecewas of the side to move, and when this was fixed, to recognize
Knight drops as coming from between board and holdings (and thus
illegal).

Fix legality testing for promotions

Turns out WB has never tested for the legality of the chosen promotion

legality testing on (when entered through the keyboard)! Now strict
testing is done, outlawing Pawns and Kings (or Unicorns in
Knightmate). Only in suicide / giveaway Kings are stillallowed, and in
spartan a black King if you do not have two yet.(And promotion
toLnce,representing Hoplite Pawn,is forbidden there.)

Reset 50-move counter on all pawn-like Lance moves

where the Lance actually participates.

Fix logo repainting

The logos were not repainted when the main window was moved out of the
display area, and then back into view. The reason for this is
unknown, as the PaintProc calls HDCDrawPosition, which was calling
DrawLogoOnDC. But the logos were not drawn, (or on an expose event
sometimes half drawn!) despite the fact that the rest of the board was.
The drawing of logos now has been decoupled from drawing the board,
and has been moved to a separate routine DisplayLogos() (in analogy to
DisplayBothClocks()). This is cleaner anyway, as the logos usually do
not change when the board does. So apart from in PaintProc, it has only
to be called when the mode changes (ModeHighlight()) or on swap clocks.
This seems to fix the problem.

Fix time in PGN info

Saving of the thinking time in the PGN was broken by the patch that
removed the race condition in the clock switching, because that moved
the incrementing of forwardMostMove to behind the code that used fmm to
index pvInfoList. As a result the time was stored in the slot for the
opponent's previous move. The value is corrected now.

Fishy fix

The move that delivers checkmate in two-machines mode is not animated
when adjudication is on. There then also is no highlighting of this move
Redrawing the board and calling ShowMove fixes it. Which is rather
strange, because ShowMove was already called in Adjudicate (when it
adjudicates), before GameEnds. For reasons that are not understood this
call to ShowMove() (which calls AnimateMove()) is not effective.

Fix WB font-based piece rendering on variant switch

The piece bitmaps were only created from the font characters when the

Fix right-alignment pproblem in WB ICS window

Use of Ctrl-R to summon the context menu still trickled through to the

In the WB menu it takes the place of the defunct Twilight Chess item.
The setup routine needed patching for setting up Lances in stead of

Fix bug in parsing variations

The moves parsed from a variation were stored in the moveList without
appended linefeed. This caused errors if the variation extended to
beyond the end of the main line,into a hitherto unused part of the move
list, as the linefeed was then not there from the overwritten move. As a
result moves sent to the engine were concatenated, triggering
illegal-move messages and bringing the engine out of phase.

Fix Edit Game/Position checkmarking in WinBoard

Because the entries in Edit and Mode menu were pure duplicats, the
entries in the wrong menu (Edit) were checkmarked while active. By
defining different IDs for those in the Edit menu, those in the Mode

2010-12-03 09:27:58 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Provide menus for editing WinBoard engine and server lists

The Edit Tags dialog in the WB front-end is adapted to act as a general
edit for string variables, by giving it an extra parameter to indicate
where to store the edited result. Menu items are added to invoke this
dialog for editing the /first, /secondChessProgramNames and /icsNames
options. This solves the problem that people would have to edit an ini
file that they can no longer locate (because the %APPDATA% folder has
different names and locations in the various Windows versions, and is
often a hidden folder on top of that).
There is a slight memory leak here, as the memory for the previous
value of the altered string option is not freed.

Configure arrow highlighting as default in XBoard

Set -highlightMoveWithArrow true in the xboard.conf file, and specify a
lineGap of 0 to make that efficient (and the wood theme even nicer).

2010-12-02 15:56:46 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Port highlighting with arrow to XBoard

Unfortuntely this duplicates a fair amount of code in the front end.
Removing the arrow is done by a total repaint if there is a non-zero
lineGap, because the clever algorithm for selective redrawing (based
on damage) that XBoard uses does not repair damage to the grid lines.
For lineGap=0, however, (for which the arrow is mainly intended) the
damage mechanism is used, and the damaged squares are determined by
tracing out the arrow in 64 steps, and marking all squares in the
neighborhood as damaged.

Fix sub-variation display with negative score

The test if the displayed score was the pvInfo score failed for negative
scores, because floats are truncated towards zero. So the previous fix
of spurious score/depth info was not working when the score was
negative.

2010-11-30 18:27:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Peel PV out of comment

Arena stores engine PVs not in variation format, but within both braces
and parentheses, before the score/depth info. This caused XBoard to
overlook the score/depth info, (frustrating, e.g., the eval graph),
while the PV would not be accessible for walking it as a variation.
The routine that extracts the score/depth from a comment now has
been made more clever, to recognize a leadin PV in the comment, and then
place it in front of the comment as variation (by moving the opening
brace to behind it). For some reason it does not work if the PV and
score/depth were separated by a newline, but this happens quite rarely.

2010-11-30 18:23:12 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow line-straddling result comments

Some GUIs (in particular Arena) do not have the decency to keep the
result comment on a single line. In this case the parser rules would not
recognize it, and treat it as a normal comment, plus an undetailed PGN
result. The rules are now fixed to allow linefeeds in the comment, and
between comment and PGN result. To correctly process the comment further
(e.g. in game-list lines) the linefeeds are replaced by spaces in the
back-end routines that do use the result comment.

Configure XBoard to use wood board texture by default

The texture pixmaps are sought in /usr/share/games/xboard, with names
wood_l.pm and wood_d.xpm. I guess the " make install" should be adapted
to put them there. XBoard is resitent to non-existence of the files,
btw. It simply ignores the arguments in that case.

2010-11-29 17:48:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Configure -inc as volatile option in XBoard

XBoard users are not used to options being persistent, and thus have
many scripts assuming the timeIncrement is -1 when they don't specify it
on the command line, and want to specify -mps. But a persistent -inc of
0 fom a preious session would then force their -mps to zero, causing
big-time confusion.

2010-11-29 14:57:00 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Improve drawing of highlight arrow

A diagonal arrow sometimes had a notch in the shaft because of
independent rounding of the starting and ending point coordinates.
Furthermore the width of the shaft was unnecessary variable(as a
function of direction) because half the width was rounded and then used
twice. Now rounding of end-points is always done towards a fixed grid
of square centers, which keeps diagonals purely diagonal, and one side
of the shaft is drawn relative to the other side, after the
position of the latter has been rounded, so any rounding error affects
the shaft width only once.

Apply gettext macros to menu texts

Now texts and references are separated, the texts in the tables can be
decorated with the N_() macro, so that the _() macro no longer has to be

files.)

2010-11-26 11:12:58 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Adapt some XBoard menu texts

The "Show" prefix is removed from the "View" menu items, as this seems
implied. An ellipsis is added to the Engine #N Settings items, which
could not be there before, because periods in a menu name would break
any reference to it. For some other names the ellipsis was deleted.
(These were not refered to, but who knows what we will do in the future.)

2010-11-26 11:03:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Separate menu text from menu name in XBoard

The text string in the menu-definition tables was used both for the menu
text, as well as for referencing the items from the code (for enabing or
checkmarking). Now these can be defined separately, so that altering the
menu texts is possible without breaing any references to the item.
(Moving them to another menu would still break XBoard, though!)
Currently the texts and names are still the same.

2010-11-26 10:48:54 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Bugfix XBoard menu translation

The gettext macro N_() was applied to the menu definition tables, but
this would break any translation, as these items are both used as menu
texts as well as reference for enabling and checkmarking. The routines
that create the menus already apply _() dynamically to these items when
they are used as menu texts.

Fix spurious scores in comments

The comment popup is also used to display engine PV info, but when the
contents of the window is written back when we select a variation,
it was treated as a real comment. This is fixed now by checing in
ReplaceComment() if the comment starts with the PV info, and if so,
ignore the latter. This solves the problem, but I guess the real bug is
that selecting a variation tries to write the comment even if it did not
change.

In stead of using it as a wildcard piece, the Lance gets the moves of
the Berolina Pawn (straight capture, diagonal move). The initial double
osh can be a ump, though. (So it is really a Hoplite Pawn from Spartan
Chess.)

Use SAN even on illegal moves

If there is only one piece of type T, moves like Ta1 or Txa1 are never
ambiguous, so adding the from square is just cumbersome.

2010-11-06 19:34:53 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use normal SAN for wildcard pieces

SAN often can also be used with pieces we don't know the moves of, e.g.
if there is only one of that type. We just always get rank or file
disambiguators if there are more (even when they might be unnecessary).

Allow arbitrary nesting of sub-variations in PGN input

The parsing of subvariations is moved out of the state-machine parsing,
to allow arbitrary nesting. In stead of the entire sub-variation being
parsed by lex as Comment, it now returns Open and Close for the
corresponding parentheses, which are then handled in a wrapper routine
for yylex(): Myylex(). Problem was that yy_text is supposed to return
the entire parsed text of the returned symbol, which thus has to be
collected. To make this possible, yylex has to return everything that it
parses, (even white space!), and a symbol "Nothing" was added to return
in parsing rules that before just ate away irrelevant text without
returning anything.

2010-11-06 21:48:47 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement setup (engine-GUI) command

This allows the frst engine (when legality testing is off) to overrule
the default opening position, in reply to the variant command. Syntax is
"setup (PIECE_TO_CHAR_TABLE) FEN_STRING"
where the FEN string is interpreted in the context of the given
pieceToCharTable (which is optional, and only delimeted by parethesis if
it is present).
Sendng the position to the second engine is delayed until the first
engine has responded to the ping after the new-game sequence, to make
sure it gets the chance to alter the position before it is sent to the
second engine. This feature is useful for playing variants that WinBoard
does not even know the opening positon for, and can be used even if they
are shuffle variants.

2010-11-06 14:19:56 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Restrict use of a2a3 kludge

The kudge to send "a2a3" in stead of "black" to get black to move is
fatally flawed in varants that have no Pawn on a2. So in that case we
revert to use of the deprecated "black" command.

When an engine announces its option features, and the option name
matches that of a setting given in -first/secondOptions, the engine is
sent hte specified value, but this value was not remembered as current
value (but the latter  was left at the engine-announced default),
leading to inconsistent behavior in the Engine #N Settings dialog.

Make test for valid promotion piece color-dependent

This is needed to make it work in variants where white and black have
different armies; quite likely white will promote to pieces that do not
exist in the black army, so we really have to make sure we test if the
white (upper-case) piece exists in this case.

Augment moves of some fairy pieces

To get better disambiguation in variants that have to be played with
legality testing off, the Elephant is given also one-step moves (making
it a so-called Modern Elephant) in -variant fairy and great. The Dragon
King (Crowned Rook), which had no moves defined for it outside Shogi at
all, has been given Rook moves plus an orthogonal 2-jump, so that it
can get SAN moves when used as Dababba or Short Rook. (Illegal moves
currently aways force long algebraic notation...)

Bugfix for safeStrCpy patch for XBoard

By a trick (temporarily redefining safeStrCpy in common.h as
((char*) (a=1/(4-3rdArgument))) ) a compile-time warning (division by 0)
could be generated for every occurrence where the size argument was equal
to 4, i.e. where the 1st argument was likely a pointer rather than an
array. These cases are now fixed. The file xoptions.c, which is the
only ne that does not #include common.h had to be fixed by making
the #define in the file itself.

2010-10-31 13:16:01 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix spurious promotions with legality testing off

The recent promotion patch had broken playing without legality testing
completely: without legality testing one always gets the piece that was
asked for, but a NULLCHAR should not be taken as a request for a piece!
But it was, and this resulted in any moved piece turning into a white
Pawn! For true promotions the piece was always black, which was also not
very useful.

Also revert to the use of '+' as internal Shogi promoChar, because
pre-processing turns out not to be possible when reading a game file.
In stead parse any trailing '+' on moves as promoChar. Downside: '++'
can no longer be recognized as checkmate symbol.

2010-10-29 22:54:18 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make deferral default in Shogi promotions

Because '+' is intercepted by the parser as check indicator, Shogi moves
are pre-processed to change a trailing '+' into an internally used
alternative '^'. The testing if a promotion character is OK is now done
in LegalityTest() and Disambiguate(), which return ImpossibleMove when
the character does not correspond to any piece, and IllegalMove when in
Shogi anything other than '^' or '=' is used. (Except for the ICS
notations.) On output, in CoordsToComputerAlgebraic() and
CoordsToAlgebraic(), the '^' is translated back to '+'.

Animate piece explosions in drag-drop moves and in XB

This required some code restructuring: the decision if an explosion is
needed is now taken in a new routine Explode() in the backend. This then
calls the front-end driver, and it returns the info if there was an
explosion or not, so the caller (AnimateMove() or the mouse driver) can
take action to repair the damage to the board caused by the blast wave.
A front-end driver for XBoard is provided as well, so that both
click-click (and replay, which is the same) and drag-drop atomic
captures are animated in XB as well as WB.
Explosions on rejected moves are suppressed.

Let -oneClickMove also work in EditGame mode

There is really no reason why people that lke one-clcik moves enough to
switch them on would not want to use them too when editing a game.
This solves a nast inconsistency, as before it used to work in -ncp mode
on the _first_ move, as the mode is then BeginningOfGame, and not yet
EditGame, and we do want it to work for BeginningOfGame, as this is
also the game mode when you start playing as white.

2010-10-27 19:40:22 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make -flipBlack and -allWhite option volatile

As these options are very Shogi specific, and the variant is volatile,
it seems logical to make them also volatile. Not completely sure about
-allWhite, though. It cold be useful if you want, for example, to play
wth dark-brown pieces for black, as any color but black looks much
better with outline pieces than with solid pieces.

The -size 64 pieces from gShogi (and originally XShogi) are made

Implement -flipBlack in XBoard

When -flipBlack is true, the white and back piece pixmaps are swapped in

Adapt WinBoard to Shogi implementation on Variant ICS

The Variant ICS does not use the '+P' notation for promoted pieces,
neither in the board, nor in SAN, but simply indicates any Gold by 'G',
and uses 'H' and 'D' for +B  and +R. The Shogi promotion code in
LegalityTest() and Disambiguate(), which are used in move Parsing, are
adapted to handle this. Deferred promotions sent to the ICS now use an
== suffix.

Enhance multi-session TC clock handling

Some new TC types are introduced: Bronstein and free sessions. The
former is implemented by letting an exclamation point '!' in front of an
increment (in the -tc string) indicate that the increment is limited to
the time actually used on the previous move. The latter is an interval
of given duraton in which you can do any number of moves (even zero),
before the next session starts. This is needed for implementing Shogi
byoyomi-type TC, as a first session, followed by a session of fixed-time
per move. The latter can now be specified with the -tc argument as a
degenerate case of Bronstein, where the time on the clock is <= the
increment (so that it is never possible to think longer than the
increment). A TC of 5 min + 10 sec byoyomi can then be indicated as
300:10+!10.

The sessions are now separated by ':' in stead of '+', and all times in
the TC string are converted to seconds first (in ParseTimeControl), so
the fullTCstring can now be directly used in a PGN tag.

Note that this patch only addresses clock handling; the engine will not
be informed yet if the TC type or parameters change at the start of new
session!

2010-10-04 09:32:18 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Remove promotion-piece encoding from ChessMove type

The shizophrenic way to indcate promotion pieces in the XBoard code
(sometimes using a promoChar, at other times relying on moveType) was
cured by combining all promotion move types (such as WhitePromotionRook)
into a single one (WhitePromotion), and relying on promoChar to specify
the piece. This solves the problem of promoting to new piece types in
variants, which formerly also required addition of new move types.

In Shogi the '+' character is now consistently used to indicate
promotions (and recognized in ApplyMove), rather than 'q' or
PieeToChar(BlackQueen), as the latter did not work in minivariants where
the Queen (representng the Lance) did not partcipate.

Suppress spurious use of SAN castling in mini variants

annoying if the 5x5 settings persisted to the next session, where you
almost certainly want to play another variant.

drops) in LegalDrop().

Revert splitting of UserMoveEvent

This splitting into UserMoveTest and FinishMove was no longer needed,
now that the new mouse driver no longer calls UserMoveTest to figure out
if a move is a promotion, and XBoard and WinBoard are unified in this
respect. It was counter-productive, because UserMoveTest was not able to
change the fromX, fromY (call-by-value) parameters for passing them to
FinishMove, so it had to defer the conversion of drop moves to internal
format to the latter, while it did not belong there. (Because
DropMenuEvent already delivers the moves in internal format.) This
whole kludgy construction was therefore abandoned, by going back
to the original 4.2.7 calling scheme, where UserMoveEvent completely
pre-processes the move, and when it is valid, calls FinishMove directly.

Make WB run-time language switch possible from menu

This is a rather involved patch that might not be worth it. It is
difficult, because translation of things that live forever is not easy
to invert (menus, the auxiliary windows). We hae to remember all
original, English texts there to be able to put them back,or
re-translate. Still does not fully work, although the menus and
temporary dialogs now are all OK.

Translate() yet. Also translate contents of combo boxes. Some small bug
fixes.

Do not translate game-end messages in PGN

The messages themselves are not subjected to _(), but in stead their
displaying in DisplayMove is subjected to T_().

2010-08-23 13:23:22 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Internationalization for WinBoard

A function Translate() was added, which uses a list of item dialogs,
reads their value, and replaces it by a translation (if available). It
also reads the window title and sets a translation. Calls to this
routine are added in the initialization code of every dialog callback.
In addition all translatable strings in the WnBoard front end are marked
by the gettext macro _(). Because WB is not gettexted yet, a hard
re-definition of this macro is added in each file using it, to the
string-translation routine T_() supplied in winboard.c.
Code to read the translation file, and translate the menu texts is added
in winboard.c. In backend.c the meaning of the gettet macros is
redefined for the WIN32 case.

2010-08-23 13:07:40 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make the ID of all WB dialog items unique

Mnany static dialog texts did share the ID -1 (IDC_STATIC). But to
replace tet at run-time for translation purposes, they need to be
addressed individually. So they were given new IDs, with symbols defined
for those.

2010-08-23 12:48:07 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Mark XBoard result messages for internationalization

The GNU gettext macro _() is used with the game-end messages. This might
be controversial, as they will appear in the PGN as well. But only as a
comment. We can always decide not to supply a translation.

Do not exit after match when match started from menu

Improved patch for expansion of WB settings-file name

The expansion of environment variables now allows multiple environment
variables in the path name. Tested on %HOMEDRIVE%%HOMEPATH%\winboard.ini
and %APPDATA%\winboard.ini.

2010-08-07 16:53:50 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add -colorNickNames option

This option allows non-standard designation of side to move in FENs.
(Useful for Xiangqi, where white is indicated often as r(ed), and Shogi,
where white is s(ente) or b(lack), and black is g(ote) or w(hite).)
Can also be used for FENs in a local language. A match of theinput
character with the nick name translates it to the standard; this means
the standard will continue to be recognized, unless it was defined as a
nick name.

2010-08-07 16:39:16 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Tricked by the grossnes

Some WB menu items were referenced by a hard number. As items had been
added over the years, the wrong menu items were grayed. In particular
the Options -> Adjudication menu was grayed out, in -ncp mode, where
this was intended for the Sounds dialog. This accidentally proved
useful, until we started to apply adjudictions also to the Human moves.
Then it was suddenly undesirable, and a small mystery why it happened at
all, when I tried to change it. The numbers are now corrected to the new
locatons of the items in the menus.

2010-08-07 16:35:23 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow match to be started from WB menu

A menu item Machine Match was added in the Mode menu to switch to
matchMode. A persistent option /defaultMatchGames determines the number
of games. A control was added to the Options -> Common Engine dialog to
set this option.

2010-08-07 16:26:35 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add some book-control options

Options /bookDepth and /bookVariation have been added to control the use
of the GUI book. In WinBoard the Optons -> Common Engine dialog now
contains fields to set them.

Fix zippy handling of draw offers from ICS

The patch by DM to fix the problem introduced by the coloration of
zippy-matched commands (namely that the coloration code beat the zippy
draw recognition to it, and ate the draw offer away) was only targeting
ICC. The new fix should work on any ICS (by using the same pattern in
zippy as in the colorization code).

2010-08-01 13:15:27 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix regression in colorization of zippy-matched commands

The patch by Daniel Mehrman from 4.2.pre8 was not properly merged, so
that in XBoard no coloration would take place of ICS commands that were
matched by zippy. (It was using &i as input pointer, rather than &backup.
The XBoard-specific code now has been deleted completely, to remove a
seemingly needless dependence on _WIN32_ of the back-end. Both WB and XB
now use the XBoard method, to only match zippy commands when logged in.

Suggest default file name in browser dialog

The argument 'def' to FileNamePopUp() was not passed through to the new
file-browser routine, which got NULL in stead, and thus started with an
empty input field.

2010-07-30 23:28:57 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Define /firstUCI and /secondUCI as synonyms for /fUCI, /sUCI

Because the %s expansion of WB options in the /fcp and /scp lines only
works for options that contain 'first' or 'second', and /fUCI thus did
not work, PSWBTM had to rely on the cumbersome /firstIsUCI=true to
install UCI engines. (The latter option should be deprecated really;
the UCI-ness of the engines is a volatile option, so it makes no sense
to supply a way to set them both to false or true. One only needs to be
able to set it to the non-default state.)

2010-07-30 23:21:50 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add string option /pieceNickNames

This (volatile) option allows definition of alternate letters for the
pieces, which will be recognized next to the standard symbols as given
in the /pieceToCharTable on input. (Output always uses the standard.)
This can be useful for reading PGN from another language, or
non-compliant FENs (e.g. using B and N for E and H in Xiangqi).
  The format of the argument is the same as for /pieceToCharTable.
Because the nickNames are consulted before the standard table, it is
possible to redefine a standard name as a nick for another piece.

2010-07-30 23:10:42 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix deadlock in match-result display

At the end of a match, GameEnds() was recursively calling itself,
through DisplayFatalError() and ExitEvent(), and the latter was then
delaying until the calling GameEnds() terminated. (Which it would of
course never do before ExitEvent returned; fortunately there was a tim
limit to this delay, but in XBoard it was 10 sec in stead of 10 msec.)
 Now the calling of DisplayFatalError() (to show the result popup) is
delayed until after GameEnds completes (and resets the anti-recursion
flag 'endingGame'), so that it is simply executed a second time, unaware
of the earlier call. But this second time it does not do anything,
because the gameMode ws set to EndOfGame the first time, and the writing
of the PGN is blocked by the checksum being still the same.

2010-07-12 11:10:17 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix WinBoard game-list title

Number of displayed games and WDL stats were always appended to the
existing title, leading to an ever-growing title in the game-list
window. Now the old actual title is ignored, and the starts is appended
to the original title "Game List". (In the future we could use the
filename here?)

In addition, the title was not updated when re-opening the game-list
window, while the stats could change if filtering was active when the
window was closed. (In that case the filter is cleared on re-opening, so
the number of displayed games changes.) Now a title-update (after
recalculating the stats) is done every time the game-list window is
opened.

2010-07-11 11:06:27 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Refactoring of material-draws adjudication code

Insufficient mating material is now determined per side individually, by
testing for MatingPotential of each side. If both lack mating potential
the game is adjudicated as draw (if the -materialDraws option is set).

This way MatingPotential() can later also be used to correct losses by
forfeit to draws (which currently is only done when the opponent has a
bare King).

The accuracy of this type of adjudication in Xiangqi has been highly
improved.

Fix bug in sending cores command to engine

The cores command was alwas sent to the engine(s) when the user changed
it through the menu, even when the engine had sent feature smp=0 (which
is default anyway). NewSettingEvent() was patched to send the new
setting conditionally, based on the engine properties as recorded in
ChessProgramStates first, second; In this particular case it now
consults cps->maxCores. (Note the code for testing the second engine
contains some dirty pointer arithmetic.)

Fix parsing of SAN shogi promotions

A missing promotion character defaults to promotion in the move type,
but the promotion character was not set when this happened in variant
shogi. And it is especially important there, as the promotion character
'+' will always be missing, as the parser will take it to be a 'check'
symbol, and strip it from the move.

Fix variant switch on PGN loading

When the PGN specified an essentially different variant, the
piece bitmaps were not properly adapted, because the switch was done by
calling InitPosition(), rather than Reset(). (The latter would destroy
the PGN tags info.) We now added an explicit call to ResetFrontEnd(),
(which is normally done from Reset()).

Remove font settings from master settings file

xboard.conf should not contain general font settings (not specific to
one board size) with specified point size. In fact it should not even
specify sizable fonts, as the new system would make specification of a
general font overrule the size-specific settings in the .xboardrc file,
so the persistence of fonts would be completely broken.

Cut board squares out of texture bitmap more cleverly

When the bitmap is larger than the entire board, the squares are now cut
out of the center of the virtual squares from subdividing the bitmap, so
that they stay centered on the grid of a Xiangqi board bitmap. If the
board size exceeds that of the bitmap, the old algorithm is still used,
as the centering would make the edge squares exceed the bitmap, and
cause a black rim around the board.

The stale-first-click fix interfered with proper handling of a piece
