Fix moves of Spartan Captain
The rewrite of the move generator did no longer pay attention to rookRange,
so that the Spartan Captain moved like a Rook.
H.G. Muller [Sun, 2 Feb 2014 15:18:07 +0000]
Add Option type 'Skip'
The value -1 used to suppress rendering of option controls was drawing

to the enum.

Detect Fischer castling in FENs
Castling rights with unorthodox piece placement imply Fischer castling.
Make sure shuffling is done after detecting this, because it means K & R
can also be shuffled (as long as K remains between both R).
H.G. Muller [Sun, 2 Feb 2014 13:09:19 +0000]
Allow shuffling indicators in FEN
If the back ranks are enclosed by < > in a FEN, the route to shuffle
initial positions is invoked on it.
H.G. Muller [Sun, 2 Feb 2014 12:51:37 +0000]
Allow wild-cards in FEN
A question mark in a FEN will now be interpreted as a piece randomly
chosen from the holdings. (From which it will be removed.) Intended
for use in symmetric black/white pairs; when used on asymetric locations
or with non-identical holdings the results will be undefined.
H.G. Muller [Sun, 2 Feb 2014 09:40:18 +0000]
Fix Seirawan reverse-castling animation
In Chess960 animation of castlings is suppressed, because the move is encoded
as KxR, so that the to-square in general is not the final destination of the
King. So it is just confusing to the eye to see the King slide to the Rook,
and then jump to an entirely different square. In S-Chess castlings can
similarly be encoded as RxK (to indicate gating at the Rook square), and
animation of those moves should be suppressed for the same reason. But it
wasn't, and in Fischer castlings denoted as RxK this even caused the Rook
to disappear when it didn't need to moved.
Perhaps one day a smart method of animating Fischer castlings can be
designed. (E.g. remove Rook, animate King move to true to-square, place Rook?
But what if the King doesn't move at all? Animate Rook then? Normal castlings
now animate the King, and then just displace the Rook.)
H.G. Muller [Sun, 2 Feb 2014 09:22:25 +0000]
Make Fischer castling generally available
A new volatile option -fischerCastlings allows every variant to be played
with Fischer castling, which so far was only allowed in variants FRC/CRC.
This only makes sense in shuffle variants, where King and Rooks might not
be in their orthodox locations. But even when they are, it has consequences
for the user interface, which will require dragging King on Rook as the only
way to enter castling. Like -shuffleOpenings the setting will be cleared
as soon as you switch variant (unless you switch to FRC/CRC, where they
Fischer castling is on by default). It can be set from the New Shuffle dialog.

A new persistent Boolean option -memoHeaders enables a new feature:

where it can be clicked again to re-open the column.
Configure maseter settings to switch -memoHeaders on by default.

Fix Tournament Options dialog
Deleting a Label option had renumbered the remaining Options, breaking

H.G. Muller [Mon, 13 Jan 2014 16:09:01 +0000]
Allow popup of TC and Common Engine from Tournament dialog
A new dialog class MasterDlg was added, similar to TransientDlg,
but to allow two dialogs to be up simultaneously. The Tournament Options
dialog was migrated to this class, so it can now get buttons to pop up
the Time Control and Common Engine dialog, like WinBoard. It even has
a button for the General options dialog.
Special care had to be taken to prevent popdown of the MasterDlg when
a Transient child is still up (similar to browser or error childs).
H.G. Muller [Mon, 13 Jan 2014 15:21:59 +0000]
Add --show-config special option
This prints a list of configure parameters, and then exits. If a second
argument is given, it only prints the value of that config parameter,
so that tricks like cp *.svg `xboard --show-config Datadir`/themes/chu
can be used in install scripts of packages with piece images.
H.G. Muller [Mon, 13 Jan 2014 13:25:30 +0000]
Overhaul kill code
Engines were not always forcefully killed in XBoard, which could make
the tournament manager hang when an engine became unresponsive to "quit".
The various levels of killing are now revised, and the -delayAfterQuit
is absorbed in DestroyChildProcess(). There is a hard killing mode 9,
which immediately sends SIGKILL, intended for engines that have already
proven to malfunction or could not start at all. In other cases SIGTERM
is sent according to specs, but a SIGKILL is scheduled -delayAfterQuit + 1
sec later just in case the SIGTERM would be ignored.
H.G. Muller [Mon, 13 Jan 2014 12:38:47 +0000]
Fix name of master settings file in OS X
The name needs to be relative to the bundle path, but ~~ expansion

Fix promotion in Ai-Wok
When in a variant with fixed promotion, such as Makruk, the promotion
piece did not participate, this led to disappearence of the piece, and
an =. suffix in SAN. This is relevant for the Makruk variant Ai-Wok,
which replaces the Met by a much more powerful Ai-Wok, which could not
be represented by another XBoard piece type due to this problem.
Now we search through the pieceToCharTable until a valid piece is found,
which works when the Ai-Wok is represented by a SMIRF Archbishop symbol.

H.G. Muller [Fri, 25 Oct 2013 12:39:23 +0000]
Implement option complex for installing engines
Options are added to allow XBoard to be called to install engines in the
user settings files. With -addMasterOption a line can be added to the
master settings file, and this will be automatically be preceded by a
-date option to record the date it was added. This is intended for adding
-installEngine options to the master file, in order to 'broadcast' the
availability of the engine to the users.
We now store the date in the user settings file, through a new -saveDate
option (as integer). This allows XBoard to relate the date of the saved
settings to -date stamps in the master settings file, and thus decide
if the latter (and install options that follow it) are seen for the first
time, or not. Depending on that it can decide if the install option should
be ignored.
The volatile Boolean optio -autoClose causes XBoard to save its settings
and exit before bringing up its GUI (but after processing the command line).
This is added to facilitate calling XBoard from engine-install scripts,
with an -addMasterOption argument.

Fix mate and stalemate test in Chu Shogi
Chu Shogi officially has no check, but we do want checkmate signs to
be displayed in SAN, and proper game-end messages to appear, rather than
force the user to play on until the King is captured. we also don't want
to allow him blundering away his King. So we don't use the F_IGNORE_CHECK
flag for Chu. But that means mate and stalemate will be recognized.
So it has to know stalemate is a win. Furthermore, check has to take
into account a possible spare royal. Finally, the + symbol to indicate
check should not be used in Chu, as in all Shogi variants this is reserved
to indicate promotion.

line is not yet already there, and either that the -versionNumber option
read from settings files or command line has a value different from the
version of the binary, or that -autoClose is set. It can be used for two
purposes: to install engines from the master settings file (so that it
only works first time after upgrades, when the stored versionNumber is
obsolete), or from engine install scripts (calling XBoard with -autoClose).

Supply oriental theme settings
Install creates a new directory .../themes/conf, in which a number of
settings files are places for defining oriental themes. These redefine the
user settings file for each of them to ~/.xboard-xxx-rc, so the settings
cannot leak into the default user settings file, but are nevertheless
persistent on revisiting the theme. XBoard now looks in this directory
for settingsfiles it could otherwise not find, so they can be invoked
with @shogi, @xq, @chu on the XBoard command line.
Filenames starting with ~~ will now be expanded to the directory where
the XBoard data files are installed, so the installed settings files can
easily refer to installed other files (e.g. piece SVGs and textures).
The themes files will also redefine the default engine when they belong
to variants that Fairy-Max does not play.
Some minor settings files for implementing variants that are not standard
(such as mini- and Sho Shogi) are also added in the conf directory.

Beef up variant detection
Testing whether an engine support a variant is now greatly improved.
Names that are substrings of supported variants are no longer recognized,
including base variants the engine only reports with a size-override prefix.
When the size is nonstandard, prefixes are always used on the searched name.
XBoard's New Variant dialog will refuse to close if the size overrides
(even if they specify defaults) do not correspond to a supported variant
of the first engine, but pops up an error box instead. If the problem is
that only one or more non-standard sizes are supported, this box reports
the first of them that is supported.
GenericReadout() had to be fixed for this, as it was not setting options
that it already thought had the correct value, so that on a second try
the size-override controls were effectively ignored.

these routines to generate moves for the (compound) piece.
