2011-04-10 20:32:57 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix use of game/position file in first match game

When a match was started from the menu, it was not paying attention to
game and position files. (Later games were.) The code that handled this
in the initialization when a match is started through the command line
was made into a routine MatchEvent, which can be called from the menu
proc too.

2011-04-09 20:55:47 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix crash on opening ICS Text Menu

The patch for the color defaults had broken the ICS Text Menu.

2011-04-09 19:22:00 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Implement Copy Game List menu item for XBoard

Some WinBoard code was cloned for this.

2011-04-09 11:42:21 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Third method of sweep selection

This method sweeps through the possible promotion choices for the piece
that is being dragged, as long as you drag a 7th-rank Pawn backwards. On
draggin such a Pawn forwards, it immediately shows it as the piece you
are going to promote to.

2011-04-08 23:39:10 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Alternative sweep promotions

The sweep takes place on the from-square here.

2011-04-07 23:21:02 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make sweep-select promotions work in WinBoard

The mouse-move handler had to be connected to the PromoScroll back-end
routine.

2011-04-07 23:19:10 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix path browsing in WinBoard

The routine BrowseForFolder was still declared as static in woptions.c,
while it was used from wsettings.c.

2011-04-07 11:14:45 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fixes to sweep selection


2011-04-06 23:47:58 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-04-06 21:20:30 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Implement sweep selection as alternative for the piece menu

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.

2011-03-30 18:17:58 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Remember Tags and Comment dialog coordinates

The save-settings code now uses the shell and shellUp arrays from the
GenericPopUp to read out the window coordinates for Tags and Comment
window. Pointers used by GenericPopUp are set topoint to the
corresponding WindowPlacement structs.

2011-03-10 19:21:59 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Redo Tags dialog

The generic popup is used for generating the Tags / EditTags popups.
The tags popup use a 'label' field to display the cmail message

2011-04-01 13:43:52 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Implement Edit-Comment window through generic popup

The Edit Comment and Comment popups are combined into one, that can
always be edited (similar to WinBoard). It uses shell number 1.
(Number 0 is for all transient dialogs.) A save-changes button is added.
The positioning is not implemented yet.

2011-04-06 10:56:57 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-04-04 19:26:53 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix animation masks on changing piece pixmaps

The animation masks were not remade when new pieces were loaded
interactively through the board-options dialog.

2011-04-04 19:09:21 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Fix linegap option in board dialog

The lineGC was not recalculated, so the grid lines stayed the same
thickness. In addition, setting the line-gap override to -1 now
retrieves the original line gap that belongs to the current board size.

2011-03-05 23:27:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-03-31 13:36:05 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-04-03 12:54:51 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Activate -path and -file options

In XBoard the generic popup was prepared for this. In WinBoard, for
-path options the BrowseFolder routine is used, and had to be made
global (prototype in winboard.h).

2011-04-02 18:40:33 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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

The ponder option was removed, as it is already in the main Options
menu, and would require nastiness in the OK callback. Added book options
in common-engine dialog.

2011-02-24 13:32:01 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Redo adjudications dialog through generic popup

We dropped the periodic-updates option, as it is already in the main
Option menu.

2011-04-01 21:56:07 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Make sounds dialog for XBoard

This uses the combo boxes. A 'play' button isimplemented for a test
sound. A sound directory is introduced, and can be set through the
dialog. A default setting for -soundDirectory is added to xboard.conf.

2011-04-01 23:11:29 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Add ICS options dialog


2011-04-01 21:52:48 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-04-03 13:15:17 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Put insertion point at end of text on SetFocus


2011-04-05 23:47:34 -0700 Arun Persaud <apersaud@lbl.gov>:
fixed 64 bit warnings by casting integers to intptr_t before casting to int


2011-04-05 23:24:24 -0700 Arun Persaud <apersaud@lbl.gov>:
removed check and #includes for malloc.h, since it's not needed

hopefully this doesn't break things on non-linux systems. OS X seems to be ok, not sure about others ;)

2011-04-03 20:23:49 -0700 Arun Persaud <apersaud@lbl.gov>:
check if malloc.h is present before including it

OS X 10.6 doesn't have malloc.h, so it complained.

2011-04-03 20:01:36 -0700 Arun Persaud <apersaud@lbl.gov>:
Fix bug introduced in commit 89b4744: removed a "/" and forgot to add it in the config file

removed a "/" to make OS X happy, but forgot to add the "/" again in the xboard.conf.in file

2011-03-12 14:08:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix display of promotion piece in ICS superchess

In Great Shatranj and Superchess promoted Pawns were displayed as shadow
piece because these variants had holdings, while captured pieces should
go back into the holdings unchanged, rather than reverted to Pawns.

2011-03-13 14:09:14 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix o-o castling in new parser

The non-compliant notation of castling with lower-case 'o' should be
preferred over the non-compliant interpretation of moving a Pawn along
the o-file. Not doing so breaks ICS play, as ICS use o-o and o-o-o for
castling! So an exception is now made for the o-file in the 'fxg'
case.

2011-03-10 19:27:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement yynewstr entry point in new parser

This entry point, used for parsing an ICS move list, was forgotten, and
was still an empty routine. This made XBoard crash when observing an ICS
game.

2011-03-07 23:11:00 -0800 Arun Persaud <apersaud@lbl.gov>:
fixed wrong default for polyglotDir mentioned in docs.

Thanks to Hans Aberg for reporting it.

2011-03-05 12:39:01 -0800 Arun Persaud <apersaud@lbl.gov>:
Fix "make install" on Os X10.6.6 (removed a "/")

seems like an extra "/" made "make install" unhappy

2011-03-03 21:19:05 -0800 Arun Persaud <apersaud@lbl.gov>:
removed parser.l from build process, also removed flex dependency from configure


2011-03-02 22:14:57 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
New parser, written in C

A new parser was written to replace the flex-generated one. Immediate
improvements are that it understand double-digit rank numbers, and Shogi
coordinates. No changes were made in the Makefile yet to reflect the
new, flexless building procedure.

2011-03-02 22:23:21 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix bugs in FRC castling rights

When parsing a castling move in FRC when no rights existed, the parser
returned 0 (= EndOfFile) rather than ImpossibleMove. The recognition of
the absence of rights was not adapted to the new encoding NoRights in
stead of -1.

2011-03-01 23:42:34 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix parsing bug of FRC castling

The code that was supposed to intercept castling when no rights existed
in FRC was not adapted to the new encoding for this by NoRights, rather
than -1, and furthermore returned 0 (= EndOfFile) rather than
ImpossibleMove. Not sure if the former would manifest itself in any
way, but the latter seems bad.

2011-03-01 23:32:25 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-02-26 21:12:08 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix flipBlack option XBoard with board texture

In XBoard -flipBlack is implemented by swapping white and black pieces,
because the Shogi bitmaps from XShogi are made that way. But the mask
used to cut out the whole in the board texture to fit the piece was not
swapped, both when drawing static pieces, as well as during animation.

2011-02-25 14:38:21 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Improve repairing damage of arrow highlight XBoard

With line gap the highlight arrow necessitated redrawing of the entire
board, to repair damage on the grid. This interfered with flashing of
pieces, which was only done on selective redraws. In stead of forcing a
total repaint we now just redraw the grid lines.

2011-02-23 16:41:36 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix unintended translation in debug file

The words "first" and "second" (cps->which) were sometimes used in
context that should definitely not be translated. (e.g. the indicator
for which engine printed/got the line in the debug file.) So translation
is now deferred to all uses in popups.

2011-02-23 16:29:12 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix nps bug

The nps settingwas tested for being > 0 in stead of >=0, so that the
case of CPU time was not properly handled.

2011-02-24 19:06:27 +0100 Kamil Blank <caceel@gmail.com>:
Added missing fclose()

Fix some resource leaks

Some files were opened not closed in XBoard, when loading XIM images
(which I doubt anyone ever does) but also when copying the clipboard
(which has the potential of being done very often). There was also some
code that would not work if conditional code which is permanently
disabled would be enabled.

Fix MSVC snprintf problem

In MSVC snprintf has to be redefined as _snprintf, and this happens
conditionally in config.c. But the latter was not #included in help.c.

2011-02-16 19:41:27 -0800 Arun Persaud <apersaud@lbl.gov>:
updated configure.ac to check for Xaw header files

check for Xaw header files when --without-Xaw3d was given. Before the test was
only done when Xaw3d was specified, but could not be found.

If Xaw3d or Xaw can't be found, print a hopefully useful error message and exit the configure script.

2011-02-16 12:03:22 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix ICS channel 0

Channel 0 messages were not displayed in the console, because the test
for channel number considered every non-numeric or non-existent handle
in a chatbox to be zero. So the messages were diverted to a non-exsting
chatbox. Now it test first for the handle to start with a digit.

2011-02-15 19:13:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make language choice from menu persistent

Set appData.language to the chosen language file, or empty if English is
chosen, so that the choice is saved with the settings. Increase the
number of possible language choices from 5 to 20. (After all, we already
have 7 now!)

2011-02-14 11:09:24 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

Fix Xiangqi King facing

The Spartan patch had broken the CheckTest for Xiangqi, because cl.check
was cleared after the King-facing test, rather than before it.

2011-02-13 22:30:59 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix variant janus size prefix

The default board size of Janus Chess was not consistently taken to be
10x8, which resulted the name to be sent as 10x8+0_janus to the engine.

2011-02-13 12:18:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix Alfil bug

The test for Alfil (suppressing single steps on the Elephant) contained
a wrong logical operator, so that it could never be active. It also
failed to include Xiangqi as variant with traditional Alfil. This led to
one-step moves of the Elephant in these variants, and false check or
unreliable mate detections.

Fix move of Xiangqi Elephant

is changed to take the first enabled one.

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.

2011-01-19 11:10:59 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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 legality testing of drop moves

Drops of noexistent pieces (i.e. with a piece indicator letter that is
not corresponding to any defined piece) are now parsed as
ImpossibleMove, rather than IllegalMove, so they are also rejected with
legality testing off.

2011-01-17 00:28:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-01-25 21:35:10 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Re-instate load next/prev position menu items

As positions do not use something similar to the game list, these are
still useful. For some reason I could not get Alt+Shift+PgUp/Dn to work,
so I settled for Shift+PgUp/Dn.

2011-01-16 21:56:14 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Remove superfluous copying of machine move

There was explicit code in HandleMachineMove() and FinishMove() to put
the move in the moveList, while MakeMove() already does this later in a
more reliable way by calling CoordsToComputerAlgebraic(). This
superfluous code is removed now.

2011-01-16 21:44:26 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix spurious mate test in Edit Game mode

When entering a game, it was terminated by the mate test even when
legality checking was switched off (so that mates might not be reliably
recognized). The mate test is now made dependent on legality testing.

2011-01-16 21:37:16 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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).

2011-01-16 21:31:42 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix move type-in truncating game

Starting a new variation by keeping Shift pressed did not work when
OK'ing the move type-in, because there was some code ther that truncated
the game. While this could be safely left to UserMoveEvent, which it
calls, as the situation is not different from entering moves through the
mouse.

2011-01-11 16:12:02 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix legality testing for promotions

Turns out WB has never tested for the legality of the chosen promotion
piece, and would allow promotion to King innorml chess even with
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.)

2011-01-11 11:34:07 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Reset 50-move counter on all pawn-like Lance moves

Now the Lance represents a Pawn-like piece not only in variant fairy,
but anywhere outside Shogi / Superchess, its moves should also reset the
50-move counter in those cases. Especially important for Spartan Chess,
where the Lance actually participates.

2011-01-11 11:18:15 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-01-10 20:36:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-01-09 00:24:17 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-01-09 00:21:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Reset machine colors after match

The colors each engine playse are set to the originals after the last
match game, so that a new match or two-machines game will not have
swapped colors.

2011-01-09 00:15:18 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Reset win/loss counters before match

The win/loss counters were not reset, because the code counted on them
being initialized to zero. But with matches startable from the menu,
this is no longer true after the first match.

2011-01-09 00:08:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Show move that causes false illegal-move claim

Without claim testing XBoard takes back moves that an engine objects to.
But when the engine is forfeited for a false claim, the move should of
course stay. So the claim test is moved to before the take-back.

2011-01-09 00:05:38 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix Spartan promotion to King

Promotions toKing were refused when in check, because XBoard thought
they would not resolve the check. Now the promotion is actually
performed before doing the check test.

2011-01-05 17:31:37 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix WB font-based piece rendering on variant switch

The piece bitmaps were only created from the font characters when the
number of ranks or files changed, because it was done in
InitDrawingSizes(). This caused missing pieces when changing to a
variant on the same board that used other pieces. Now InitDrawingSizes()
is called for any variant switch.

2011-01-05 17:25:11 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix right-alignment pproblem in WB ICS window

Use of Ctrl-R to summon the context menu still trickled through to the
default text-edit window routine, and caused right-alignment. This was
because the text-edit reacts on keyDown rather than the character event.
KeyDown of R with Ctrl pressed is now also intercepted and ignored.

2011-01-03 13:04:56 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix chat window title

The title was using the engine name, rather than the ICS handle, which
did not work outside zippy mode. Now it only uses the engine name when
no ICS handle is known. The titleis now also subjected to translation.

2011-01-03 12:50:54 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix spurious reading of old game title by JAWS

Because focus was switched to the board window before loading the
selected game from the game list, the titlebar still contained the
name of the previously loaded game, which would spontaneously be read by
JAWS. Now the focus switch is done after loading the new game (which
updates the window title.)

2011-01-03 12:37:17 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add variant Spartan Chess

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
Pawns for black, the check test had to be adapted to handle duple check,
Alfil and Dragon moves were fine tuned in this variant to make the exact
moves, and the promotion popup was adapted to show King and interpret
Rook and Bishop as Dragon and Alfil for black. The Alfil now always
moves as Modern Elephant except in Shatranj and Courier.

2011-01-03 12:23:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix mate test

Due to a bug in logical operators drops were tried for mate evasions
even in non-drop games, which broke it in Superchess and Great Shatranj,
and wasted CPU time in other variants.

2011-01-05 17:19:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix promotion suffixon disambiguated piece moves

The promotion suffixon piecemoves that needed disambiguation was not
passedon to the back-end in most variants. Now it is passed on in any
variant.

2011-01-03 12:08:19 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix promotion of Pawn-like Lance

In variants where the Lance is used to represent an unorthodox Pawn, it
must promote when it reaches last rank. With legality testing on,
however, the promoChar was ignored in ApplyMove in this case. The
promotion suffix also was not appended in SAN moves.

2011-01-03 11:57:23 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix WB promotion popup

The promotion popup did not work properly in variants where black did
not use the pieces that white wanted to promote to. Now the character
for the selected piece is taken from the piece encodings of the side to
move. In addition, selection of undefined pieces is ignored.

2011-01-02 14:17:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2011-01-02 14:11:45 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Define Ctrl-R as right-click in WB Comment dialog

To allow JAWS users to load a variation through the keyboard, Ctrl-R is
equated to a right click at the position of the caret or selection.

2011-01-02 14:06:14 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Disable some accelerators in JAWS version

Single-key accelerators that could result in irreversible data loss are
undesirable, because the risk of accidentally pushing them is too large.
So the non-Alt duplicates of next/previous game/position are disabled,
as are Home and End for Revert and Truncate Game. JAWS users will have
to rely on the menus for those functions.

2011-01-02 13:59:01 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Group engine-output memos with engine names

The engine names are now defined just before the text edits, so that
JAWS 11 will read the engine name when the memo for the output of that
engine is selected. (JAWS 10 will still read the NPS, as it reads in
geometrical order.)

Subject WB context menus to translation

The innerloopof the menu translation has been made into a separate
routine. This now uses GetMenuItemInfo() in stead of ModifyMenu() to
better preserve menu breaks. Menu #10 is used for context menus (from
the routine that pops them up), and for this number the orignal texts
are not saved in menuText. (This is not needed, because the menu is
created everytime anew from the resource data.)

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.

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 fag-fell marker with logos on

The flag-fell marker "(!)" that is displayed in the clock in WinBoard in
two-machines mode was printed twice when the clock was split over two
lines (as with logos on).

Also exempt variant seirawan from eval-scale doubling

It is not really a drop game, so a scale from -7 to 7 in the eval graph
is good enough (like variants great and super).

Configure EGTB cache size in adapterCommand

The hash size, nr of CPUs and EGTB path are transferred through the WB
protocol interface commands memory, cores and egtpath. But there is no
WB command for detailing the EGTB cache size. So the value of the
command-line option -defaultCacheSizeEGTB has to be sent to Polyglot
through its startup command to make it known to UCI engines.

2010-11-30 21:25:07 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2010-11-30 12:22:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Write key bindings in XBoard menus

Unfortunately tabs are not understood in menu texts, so fine-tuning
through spaces is necessary to get some sort of ragged alignment.

2010-11-29 18:01:38 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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.

Make WinBoard clocks translation-proof

With logos on, the splitting of the clock over two lines assumed the
lengths of the words "white" and "black" would always be 5. Used strlen.

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.

Update texi file for new menu organization

The descriptions are shuffled around and organized into sections
corresponding to the new main menus. Where necessary the name of the

menu (the next/previous/same stuff) are nowmoved to the section "other
shortcut keys", as the key bindings for some of them are still active.

Update info on key bindings in texi file

The texi file was still listing the old XBoard key bindings. Where
necessary this is now changed to the new (WinBoard) bindings, and all
the new bindings were added.

Divorce the Edit and Show Tags/Comment menu items

In WinBoard the items in the Edit and View menu for Tags and Comment now
have different IDs, so they can be independently controlled. Only the
items in the View menu are check-marked. The items still do the same.

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
applied when they are used. (This makes the texts appear in the .po
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.

Let Analyze File annotate the loaded game

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.

(First) up-clicks were not always ignored: in Edit-Game mode with

InitPostion(). Suppress putting captured pieces in holding. Let
promoChar indicate gating in ApplyMove(). Remove gated pieces from
the holdings there. Let GenLegal() generate RxK-type castlings to act as
base for gating on Rook square. Gatings are tested for legality
based on the holdings content and whether they occur on the back
rank. Disambiguate() also tests this. Make sure the gated pieces are
printed as move suffixes in CoordsToAlgebraic().

If the second engine is not yet running, it would be impossible to use
the settings dialog for it, as the features have not been received and

starts the engine, and delays the appearence of the popup untill the

Fix bug in parsing illegal Pawn captures

When a pawn move of type exf5 was illegal, the parser made an attempt to
interpret it as e.p. capture of f5. This, however, messed up the move,
so that it was now permanently mistaken for e5xf6. Even in cases with
legality testing off, where you would want the original move to be
accepted despite the fact that it was illegal.

Keep last PV while clearing engine-output display

When ponder is on, the display is cleared immediately when the last line
of thinking output appears by the appearing ponder output. So you would
never get the chance to see it. This line is now re-written after

2010-11-06 19:45:18 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Give Lance moves of Berolina Pawn

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.)

2010-11-06 19:42:16 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
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

Restrict use of a2a3 kludge

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.

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)

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.

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.

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.

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

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',

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 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.

2010-08-07 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>:

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.

2010-07-31 22:48:45 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2010-07-11 10:54:59 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2010-07-05 09:55:14 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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()).

Adjudicate Xiangqi material draws with Advisor-less Cannons

2010-07-05 09:34:21 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2010-06-30 10:52:27 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
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.

2010-06-30 10:49:12 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow -flipBlack to work with font-based piece rendering

flipView for variant shogi when -flipBlack is off.

2010-06-30 10:46:43 +0200 H.G. Muller <h.g.muller@hccnet.nl>:
Allow font-based piece rendering in board sizes below petite

to using bitmaps is not really an option anyway.

Fix game end during dragging

The stale-first-click fix interfered with proper handling of a piece
being dragged when a game suddenly ended (because of opponent resign,
or caling the flag), because up-clicks when the from-square was reset

DragPieceEnd() and redraws the board.

Alter XBoard key bindings to mimic WinBoard

A lot of new bindings were added, and four menuProcs had to be registered
to be able to add bindings to them. The use of the control key as

keystrokes, and this function was migrated to '.'. The iconify function
had no shortcut in WinBoard, but to get rid of letter bindings it was
migrated to '-'.

Suppress background observe for boards with own game number

This is really a work-around for an ICS bug. The Variant-ICS sent the
initial board of a game in a move list with relation = 0, which means
'observed'. So XBoard was thinking it was observing its own game, and
switched to dual board. It seems harmless to suppress such a switch for
all boards of your own game, however, which is now done.

This reverts commit a02042ef83ce1f3632f0cf3e0a2a4ce9a3ac5d85.

2010-02-25 20:32:23 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add -autokibitz checkbox to UCI-options menu dialog


2010-02-25 20:29:45 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Also capture (numeric) whispers of players for -autoKibitz


2010-02-25 20:25:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add kibitzes and c-shouts Chat Box

A box dedicated to c-shouts will snatch any c-shout before it is
diverted to a normal shouts box. The kibitzes box can capture the
left-overs of -autoKibitz, if the latter is active.

2010-02-25 15:45:16 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Mark non-compliant lines of engine in debug file

The option -engineDebugOutput is extended to accept value 3 for printing
a cear indication of non-compliancy in the debug file.

2010-02-25 12:02:58 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Redraw second board on expose events

The -dualBoard option now does refresh the second board after another
window uncovers it. To acheive this, some data structures remembering
what is displayed had to be duplicated. (lastBoard and damage for XB,
lastReq, lastDrawn, lastReqValid and lastDrawnValid for WB.)
WinBoard now uses clipping also for second board. This required the
clips for the destination to be translated horizontally!

2010-02-25 15:13:00 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Print seconds with 2 digits in backgroundObserve status line


2010-02-24 17:01:23 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Do not recognize non-ICS variants from PGN event tag

These variants were introduced after supporting the variant tag, so if
the variant tag is missing, their recognition from the event tag will be
a false match. (Mainly to prevent events with 'super' in the name being
recognized as Superchess.)

2010-02-23 13:52:51 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix display of uninitialized boards in background observe

A variable partnerBoardValid is cleared on starting our own game, and
set when a board from the background game comes in during it. At the end
of our own game, a valid partner board now is put in the display.

2010-02-23 13:46:25 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add option Display Logo in WB general-options menu

Changing the option requires InitDrawingSizes to be called for
re-formatting the board window. Switching it off requires clearing of
the cps->programLogo fields to take effect immediately. Switching it on
only takes effect the next session, as we will need some refactoring to
redo the figuring out what logos to display.

2010-02-22 12:02:59 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Group Chat Boxes with console in stead of board window

They now open and close with the console, which seems more natural, and
prevents the console from covering them.

2010-02-22 11:50:59 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Put new options in WB ICS-options dialog

The Seek-Graph, background-observe and Chat-Box options are added to the
ICS options dialog. They only control the appData settings, there are no
special actions yet on switching the settings.

2010-02-22 11:46:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Create space in WinBoard ICS-options dialog


2010-02-20 12:42:09 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use side-by-side boards to display background game

A game observed in the background (i.e. if -backgroundObserve true) will
be displayed right of the normal board in the same window if the new
(persistent) Boolean option -dualBoard is also set.
Very flakey hack, especially in XBoard, where clocks and messsage
field all get the wrong width (and resist adjustment in the strangest
ways). The clocks of the partner game are not yet displayed, and
disaster happens when the background and foreground games do not have
the same board format.

2010-02-23 14:57:01 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Repair background-observe patch

Apparently a commit was lost that I collapsed with 3018a6 while the
latter was already pushed to savannah. Here I recreated this commit from
a diff between the respective commits in the savannah & nubati gits.

2010-01-31 11:07:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Repair settings-file name

The default name is put back to /etc/xboard/xboard.conf, so that XBoard
can again find its settings file. "make install" will still install it
in the wrong place.

2010-02-21 18:43:59 -0800 Arun Persaud <arun@nubati.net>:
new developer release


2010-02-21 19:45:58 -0800 Arun Persaud <arun@nubati.net>:
fixed compiler warning for file-browser code

missing "void"s in the function declaration and missing returns showed up when trying to build on the opensuse build server. fixed now.

2010-02-21 23:09:24 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Put newly opened Chat Box on top

Dialogs always pop up in front, so set the onTop variable that prevents
highighting the button to navigate to it from other Chat Boxes
to reflect that a newly opened Chat Box is in view.

2010-02-21 18:55:03 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix copying of kibitzed info in Engine-Output window

Make sure all lines end with "\r\n" to not lose line breaks on
copy-paste from the memo. (XBoard would strip those again.)

2010-02-21 18:25:45 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow walking a kibitzed PV

If no tabs are found in te 'thinking output' we assume it is a captured
kibitz message, and look for "PV=" to locate the start of a PV in it.
Also try to include any continuation lines below the selected line.

2010-02-21 17:45:37 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Insert autoKibitz continuation lines at end of line

In the engine-output window lines that start with the ICS continuation
sequence "\   " are inserted behind the line they belong to, in stead of
at the top. This required keeping thrack of the length of the currently
active line in OutputKibitz().

2010-02-20 15:39:29 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Don't disturb background observe when receiving new piece

When new holdings are sent when the background game is displayed, we now
ignore this, as presumably we are peeking at our partners game, and thus
should be well aware of what is captured there.

2010-02-19 21:52:06 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Newly lexed parser in XBoard directory


2010-02-19 11:18:21 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Let yy_text determine progress of PV parsing

The parsed unit yy_text was not available after ParseOneMove(), because
the buffer switch in yylexstr() apparently destroys it. To solve that,
yylexstr() now is equiped with an extra buffer argument, where it copies
yy_text before the switch, so the caller, ParsePV(), can see what was
parsed in yy_textstr. This is used to update the PV pointer, but also to
save any parsed comments (when ParsePV is used for parsing a PGN variation).

2010-02-18 17:42:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Support playing through PGN variation comments

Right-clicking a variation line in the comment dialog will shelve the
current variation, and parse the comment to replace it. This uses
ParsePV() in an alternative way, for which the latter had to be
enhanced: it was made resistent to move numbers and comments inside
the PV. It now has an argument to indicate if such comments should be
stored with the moves. The Comment Popup is closed on revert, to
make sure no comments to moves that are destroyed, containing
variations on a non-valid line, can keep hanging around.

2010-02-18 16:05:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add Annotate item in Step menu

This does the same as Revert, except that it adds the destroyed
variation as comment to the original movem in PGN variation format.
RevertEvent now has an argument to indicate if it should add the
comment, or not. Comments in the abandoned variation are included in the
varriation command to the main line. (The exact layout of the variation
comment that results leaves still to be desired.)

2010-02-15 19:07:12 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add option -shuffleOpenings

This volatile option is added just to make the existing variable
available from the command line, not only from the menus.

2010-02-19 11:48:49 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Let the sounds sound on receiving a message in a Chat Box

Use Colorize() to the applicable color to trigger the sound, and then
restore the original color as 'continuation', to do it silently.

2010-02-10 10:55:51 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow WB Chat Box to be dedicated to shouts and 'it'

By putting 'shouts' in the handle field, a chat window will capture all
shouts and c-shouts, and send messages typed into it as shouts.
The bracketing of the shouter name now indicates the type of shout.
The handle for WHISPER Chat Boxes has been changed to 'whispers', to
make it easier to pop them up by clicking the console.

2010-02-16 22:34:23 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add -chatBoxes option to open Chat Boxes at startup

This string option contains a semicolon-separated list of handles for
which Chat Boxes should be opened at startup. The value saved in the ini
file is the value that was read, not the actual chat boxes that were
open at the time of saving.

2010-02-16 19:44:46 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make Chat Windows pseudo-tabbed

By adding buttons in every Chat Box to navigate directly to every other
Chat Box, a stacked set of Chat Windows behaves like a single tabbed
window, but can still be unstacked. The buttons turn grey to warn that
new text appeared in hidden boxes (i.e. not the one last brought to top).

2010-02-19 21:46:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow arrow keys in WB Chat Box to access command history

The history is shared between al boxes and the ICS console.

2010-02-12 22:35:11 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make WB Chat Boxes wrap and handle URLs

Cloned the code for the console text field to hande URL. (Initialization
to recogize the link, and notifiction to open it when clicked.)
Removed the ES_AUTOHSCROLL style from the RichEdit in the resource.

2010-02-10 10:58:29 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix copying of WB Chat Window contents

All line breks were lost on copy-pasting the contents of a chat window.
Adding CR to each outputted line in the front-end (wchat.c) solves this.
(Tell messages sent to a handle (which are not echoed by the ICS, and
thus have to copied to the chat box directly) also need CR!)

2010-02-19 22:34:30 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add upload of game to ICS for examining

New item "Upload to Examin" in Action menu, calls UploadGameEvent().
Use SAN moves to upload game to ICS, rather than long algebraic
(The ICS did not understand long-algebraic promotion moves)
Use bsetup within examine to set position onFICS, and also variant.
Castling rights do not work yet for FRC. Totally different set of
commands are needed on FICS and ICC.
 FICS does not understand w23 or wild/23, but needs 'crazyhouse' in the
besetup command that specifies the variant. XBoard variant names are
used, except for fischerandom, which is 'fr'. Things like nocastle will
probably still not work.

2010-02-18 17:41:10 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Handle display of PV that starts with other move than played

Insert the retraction of the played move, without premove highlighting.

2010-02-16 19:36:18 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Bugfix smart capture

Disambiguate was changed to make sure that for ambiguous moves, a
capture would always prevail in the closure, rather than the last move
that happened to be generated. Before, double-clicking a piece would
sometimes plsy a non-capture.

2010-02-13 15:34:04 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix XB crash on giving keyboard focus to non-text widget

In the Engine-Settings dialog SetFocus() could be called for non-text
widgets, and this made XawTextSetInsertionPoint() croak. Setting the
insertion point to the end in SetFocus() was a bad ide anyway, as it
interfered with copying from the engine-output window, which would
uncontrollably scroll on getting focus. It is solved now by setting the
insertion point already on creation of the text widgets.

2010-02-19 22:32:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Seek-Graph bugfix: disappearing output in ICS console

Suppression of output to the cosole was handled fundamentally wrong: it
was not enough to set next_out to after the unit that should be
suppressed, as there can be a backlog in printing of previous units that
came in the same packet. So this has to be flushed first, or it will be
lost. -autoKibitz probably got away with that, because it comes in a
separate packet. But seek ads are often suffixed to other output, and
then that output disappeared! Now we flush everywhere before suppressing.
We now totally rely on the prompt to restart the printing, so that
acknowledgements following the echo of the sent message are also
suppressed. Also suppress LF before diverted chat messages.
  Also fixed is the 'mamer bug' in Chat Boxes, due to false parsing of
a "* (*): " pattern in tell messages, because of a missing continue.

2010-02-12 18:08:29 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Pop up ICS text menu with default item under mouse pointer

The menu popup is migrated to the down-click (was up-click), so the
up-click can select the item. Some trickery is needed to fool the menu
into thinking that the mouse moved, so that a moveless up-down click in
the ICS text field selects the default item (the upper-right one).
Also allow dummy item in ICS text menu: The command "none" in the ICS
text menu will now be treated as a grayed-out (disabled) entry, so it
can be defined in the position underthe mouse pointer to prevent the
up-click from doing anything, while keeping the menu open. Recommended
for use with an entry of spaces.

2010-02-10 14:42:49 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow ICS context menu to pop up a Chat Box on clicking handle

A command "chat" defined in the WinBoard icsMenu string will cause
ChatPopUp() to be called when it is clicked, with the clicked handle
(name) in the ChatPartner field, and focus on the input field.
ChatPopUp() had to get a parameter (the handle) to make this possible.
If that parameter is NULL (as when it is called from the Mode menu),
focus will still start on the (empty) ChatPartner field of the box.

2010-02-10 10:50:11 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix right-edge spillover of Seek-Graph dots in WinBoard

Rescale the X-axis to allow margin for dot size and color offset.

2010-01-30 11:05:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Interface XBoard to GhostView file-browser dialog

Note: The Ghostview dialog was using some deprecated variables for error
printing, and conditionally used getwd() on some systems that presumably
do not have getcwd(), but it did not assess the latter properly.

2010-02-09 14:38:09 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow recalling history in ICS input box with arrow keys

By adding translations for the Up and Down keys, and stealing some code
from winboard.c. Still needs some refactoring to move the duplicate code
to the back-end.

2010-02-09 14:34:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Start insertion point at end of text edits in XB dialogs

The function SetFocus now uses XawTextSetInsertionPoint to position the
end of the string it aready contains, rather than at the beginning.

2010-02-08 17:55:44 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Capture holdings of background observed game


2010-02-08 11:57:57 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Match handles with multiple titles for channel Chat Boxes

Only handles with at most one suffixed 'title', such as (U), (C), (IM)
or (TD), followed by the parenthesized channel number, were recognized,
so tells by people with more titles always went to the ICS console window.
Patterns are added to recognize handles with upto three such qualifiers.

2010-02-08 11:54:55 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Do not pop down Seek Graph on on-dot click

Leave the graph up, and let the incoming board of a started game cause
the pop-down. This in case the clicked ad is no longer vailable, or
manuay refused, and fails to start a game.

2010-02-07 21:26:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Observe a game in the background while playing

A new (persistent) option -backgroundObserve true|false is added. When
set, observed boards received while playing a game will not trigger a
game switch, but will be ignored except for storing in a dedicated board
buffer. Pressing the right mouse button will cause the board to be
displayed, until we release it. Time, strength and stm are always
displayed in the message window.

2010-02-07 16:43:36 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Remove race condition in clock switching

The move number is now incremented inside SwitchClock, when no timer
interrupt is scheduled, so the interrupt cannot occur at the wrong side
of the increment, and decrement the wrong clock.

2010-02-07 11:53:03 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Let second click on piece make only capture, with -oneClickMove

Normally this would clear the highlighting of that piece.
Required new field in DisambiguateClosure to count nr of captures.

2010-02-07 11:18:56 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Bugfix stale first-click

When the opponent resigned after the user had cicked a from-square,
clicking the from-square for the first move in the next game would
produce an "illegal move" message, because it was considered a to-click!
We now set fromX and fromY to invalid in GameEnds().
Should we also reset them on mode changes?

2010-02-07 11:08:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add promotions and e.p. to oneClickMove

For e.p. the to-Square of the Pawn has to be clicked. Promotions are
always to Queen when you click the to-square, but use the promotion
pop-up when you click the from-square.

updated year in copyright info


2010-02-05 22:27:51 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
One-click moves

Playing on ICS or against engine, clicking a square from or to which
only a single move can be made causes the move to be done, when the new
option -oneClickMove is set to true.

2010-02-04 16:09:25 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use squares for computer seek ads

Shape indication passed in sign bit of color (char) variable.

2010-02-04 22:46:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use right mouse button to view seek ads

Right down-click does the same as left down-click, right up-click
simulates a left up-click off board (so it misses all dots).

Use right-click miss to refresh Seek Graph

The 'moving' parameter had to be made into an int for this, to indicate
right clicks with code 2. Right press now already pushes the clicked ad
to the back, so that the up-click will display an underlying one.

Bugfix pushing back seek ads on right-click

On a right button press the previous in stead of currently hit ad was
receiving the penalty.

Indicate seek-ad multiplicity

If more than one seek ad is inside the capture range of the mouse
pointer, an exclamation point is printed before the seek-ad text.

Some fixes to make seek-ad suppression work in WinBoard

In WinBoard the z-depth was immediately erased by redrawing the graph;
the clearing of zlist had to be moved from PlotSeekAd() to AddAd()
(where it really belongs). Also aging of z-depth is now suppressed on
mere pointer motion.

2010-02-04 22:45:01 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Dynamic Seek Graph

The new option -autoRefresh sets FICS and ICC to report removal of seek
ads, and then removes those from the Seek Graph. New seek ads are added
to the graph, as soon as the ICS reports them.

2010-02-04 22:42:15 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement SeekGraph in XBoard

For now only controlled by left mouse clicks on board. New options
-seekGraph true|false and -sg to switch this feature on.

Facilitate selection of coinciding seek ads

Seek-ads that are viewed but not answered get a distance penalty on the
up-click that makes their selection more difficult next time, so that
the ad they covered gets a (better) change. The penalty ages away in the
course of 5 clicks.

Slightly offset Seek-Graph dots of different color

Dots of different color are now displaced horizontally be 3 pixels, to
prevent them from completely covering each other. (Required the axis
labels to be moved a little too, to not be covered by the 1-min ads.)

Auto-show seek-ad texts in WinBoard

Hovering the mouse above a Seek-Graph dot will make the text belonging
to it appear in the message field without the need to press a button.
Required SeekGraphClick() to be called from the WB mouse event handler,
with an extra argument 'moving' to make the distinction with a real
click.

Show seek-ad text on mouse hovering (XBoard)

The Eventproc is also set to trigger on PointerMotion, and this event
then calls SeekGraphClick with motion=true to handle it.

Put poetic name of wilds in seek-ad text

Use XBoard variant names, except for 'loadable' and 'fischerandom'
(becomes 'setup' and 'chess960'), but leave number (to distinguish wilds
that transate to same XBoard variant).

2010-02-05 20:36:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix highlighting bug in XBoard

The from-square was drawn before the to-square was erased, which led to
a missing highlight line if they shared an edge or corner.

2010-02-05 14:39:55 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Repair damage to -autoKibitz done by FICS atomic zippy claim

The sending of -autoKibitz info was also moved back in that patch, but
unfortunately to after clearing of the programStats info. Now the
clearing has been moved also, to remain after it.

2010-02-04 23:33:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Send continuation lines to chat box they belong to

The variable savingComment is used as a kludge to remember where the
comment should go (i.e. which chatbox, or elsewhere), so that when a
continuation line is matched, chatPartner (which was reset at EOL) can
be restored to its original value. Also put space after handle of talker
in channel Chat Windows

Fix u64 format for cygwin

With a -mno-cygwin compile %llu and %lld are definitely not understood
by scanf and printf, although they are by the compiler. In stead, %I64u
seems to work. Put it in under control of a switch USE_I64, which is
defined only in the gcc makefile when MINGW is used.

Fix bug in display of logos

The logo continued to be drawn after a boardSize change to a tinyLayout

Right-click refactoring: step III

Let WinBoard call RightClick in back-end, and delete the duplicate code

act depending on the result returned by RightClick.

2010-01-19 19:07:15 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Right-click refactoring: step II

Migrate the Right-click routine to the back-end. Let it communicate back
square coordinates through pointer arguments, to accomodate their
different naming in XBoard and WinBoard. Template added in frontend.h.

2010-01-19 17:55:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Right-click refactoring, step I

Divorce front-end part from back-end part of PieceMenuPopup in XBoard
front-end, and forge the back-end part into a new routine RightClick.
The right up-click in XBoard, which called unLoadPV() directly, now
calls RightClick through PieceMenuPopUp().

Merge gamelistopt sources into gamelist source files

The files xgamelistopt.c and gamelistopt.c are merged with xgamelist.c
and gamelist.c, respectively. The WB front-end for the dialog already
resided in winboard.c, so there was little need to move it to wgameist.c
file. Makefiles adapted accordingly. Unsuitable key bindings were
removed. The low-level front-end prototypes are now defined in in
frontend.h.

2010-01-29 21:47:47 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Game-List options dialog for XBoard

A dialog similar to that of WinBoard was cloned from the game-list
window. The XBoard front-end is in a separate file xgamelistopt.c,
which in fact implements most of the low-level front-end as back-end.

2010-01-29 12:48:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Refactoring of game-list-options dialog

The back-end part is separated off, and moved to a file gamelistopt.c.
Front-end for now stays in winboard.c. No prototypes in frontend.h yet.

2010-01-26 19:28:43 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix of ancient WB bug: test integer option values for validity

Only a string of digits preceded by an optional sign is accepted now.
Before, any string was accepted, and leaving out a value could lead to
the next option being ignored (if it did not need a value) because it
was considered the value for the previous one!

2010-01-26 19:00:54 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix bug in edit-position of holdings

The holdings were effectivelly taken one too large, so that a promoted
shogi Pawn moved to, or created in the holdings was not demoted to Pawn,
but put in the dark (which you could see by the holding count if you did
it twice). The overflow tests in these two cases now have been corrected.

2010-01-25 13:54:40 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Save fonts in XBoard settings file per boardSize

Each -boardSize now can have its own font specified in the settings file
(and thus by a command-line option, although it would in general not be
very useful to specify a font for a size other than the selected). E.g.
a prefix "size33:" to the font name will apply it only to -size 33.
An unspecified-size font option (not normally in the settings file) will
always prevail over a font option specific for the current size.
A font of some size must have been used or specified in order to be
saved.

2010-01-25 08:56:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix width of filter field in XBoard GameList

An empirical dependence of the width of this text edit on the square
size now makes for an acceptable layout at any board size.

2010-01-24 19:09:45 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use FICS atomic draw claim for sending move in zippy mode

For this the relaying of the move had to be moved until after the
adjudication, which again has to be done after MakeMove(), which is a
bit dubious, as MakeMove might take significant time when animating.

2010-01-24 18:51:38 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Send FICS atomic claim to ICS if move creates draw after offer

The FICS format "draw MOVE" is used to send the move to the ICS  when
the user enters a move that adjudicates as a claimable draw, and he
offered a draw before the move. For the benefit of ICS that do not
understand this format, the plain move is sent afterwards.

2010-01-24 18:16:14 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Also allow user to claim by offering draw before his move

Use the existing userOfferedDraw variable to test for such offers in
Adjudicate().

2010-01-24 17:29:42 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Also adjudicate after user move

Call Adjudicate() in FinishMove().

2010-01-24 15:56:56 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Refactoring of adjudication code

Put all the rule-based (as opposed to score-based) adjudications in a
separate routine, so they can also be called on user moves. This
requires sending the drawing move to the opponent engine to be made
conditional on existence of the latter. Execution of the code is no
longer dependent on the condition TwoMachinesPlay, but actual game
terminations are now all restricted by an alternative condition (no ICS
mode).

2010-01-24 11:46:30 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use -keepAlive option to determine connection health

When there has been no ICS response since the previous 'ping', assume we
are disconnected and do a fatal-error exit. Also auto-start the ping
process in InitBackend3().

2010-01-23 23:00:10 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use arrow keys in XBoard GameList for entry selection

Add translations for arrows and home/end, to call LoadSelectedProc with
argument to indicate the step, and let the latter perform the action.

2010-01-23 22:24:20 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow <Enter> to apply filter in XB GameList filter edit

Apply a translation to intercept the <Enter> key. Set focus back to the
list display afterwards.

2010-01-23 21:44:36 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Accept <Enter> for changing chat partner

A kludge stolen from Alessandro's GameList filter allowed to let the
typing of <Enter> while updating the chat-partner field of the WinBoard
chat windows to act as pressing the Change button. Gives focus to the
input field of the window afterwards.

2010-01-23 21:42:38 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Move duplicat gamelist code to backend

The filtering routines are moved from xgamelist.c and wgamelist.c to
gamelist.c, and a prototype for them is placed in backend.h.

2010-01-23 19:29:18 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Port game-list filtering to XBoard

Added a text edit and apply button to the XBoard game-list dialog, and
only have it print those lines that match the filter. Translate index in
list to index of game in file when a game is selected, and index in file
to index in list when a line is highlighted. Duplicates some code
between xgamelist.c and wgamelist.c, which should be moved to back-end.

2010-01-21 19:24:49 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Convert to DOS line endings

For easier understanding of upcoming diffs of winboard.c

2010-01-21 14:32:46 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Refactoring of move-history code

The WinBoard code in whistory.c was split in a front-end part (remaining
in whistory.c) and a back-end part (now in history.c in the xboard
directory). This to allow easy porting to other platforms.

2010-01-20 12:48:30 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add fixed-time/move button in XBoard time-control dialog

Put the TC-type buttons in a radio-group, and highlight the selected mode.

The PV was unloaded on anything but a button release, in stead of the

We now use the position of "Chess with Different Armies", FIDE army vs.
a fantasy army (inspired on the Color-bound Clobberers) as opening
position.

Add variant Makruk

Thai Chess, played by 2 million world-wide. Required pawn promotion to
happen in a zone, and the Alfil to move as Shogi Silver, a new opening
array, and unusual Pawn placement. Because of the latter, I consider it
a setup position, so a FEN will always be sent to the engine.

2010-01-17 14:17:10 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix parsing of O-O and O-O-O after FEN pasting in FRC

Because the initial rights were not set in the FEN reader, the
initial rights of the previous game remained in force, so that the
parser did not understand OO-castling (although it would allow KxR
castling).

2010-01-15 14:40:43 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix reading FEN castling rights for knightmate and twokings

Scanning the back-rank for a King did not work in these variants,
because either the Unicorn castles, or there might be two Kings.

2010-01-13 11:42:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix omission in castling refactoring for ICS received boards

A default of -1 was still used, in stead of NoRights, when no Rook was
found. In theory this could have had effect in a setup board 0 in FRC,
when there were no Rooks on the back rank.

2010-01-13 11:35:34 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix TwoKings ICS castling-rights bug

Scanning the rank (as is done because of FRC) assigned castling rights
to the rightmost King. Even scanning the opposite direction would not
work, as it is not always the eftmost King that can castle. So we now
explicitly test for a King on e1/e8 in TwoKings and assign it rights,
relying on the Rook rights received from the ICS to control castling.

2009-11-18 19:12:25 -0800 H.G. Muller <h.g.muller@hccnet.nl>:
fix double start of zippy engine after switch to gothic

In ICS mode we now switch to the proper variant as soon as we receive
the generic game-start message, to prevent a mismatch when the first
board is received (which would trigger fetching of a move list).

2010-01-11 16:44:40 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Extensive bugfix of -autoKibitz

Suppression of printing of diverted kibitz messages failed when they
extended over more than one read. This could even lead to such
messages being erroneously saved as comments, which then lead to
crashes. The suppression mechanism now waits for a prompt, in stead of
the end of buffer. This required the printing of any leftover in the
buffer to be deferred until the next read completes it.
The number of people kibitzed to is now printed.

Dragging pieces to and from the holdings now consistently keep track of
the home square of pieces and the piece counts, as does creation of
pieces in the holdings through the piece menu.

Indicate squares a lifted piece can legally move to

Under control of the new option -showTargetSquares when
-highlightDragging and -testLegality are on, the squares a piece can
move to are marked by fat dots in the highlightColor (non-captures) and
premoveHighlightColor (captures), as soon as you grab it for dragging.
In variants with mandatory capture, the capture target of other pieces
is marked with the highlightColor (as non-captures are then not allowed).
