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

2012-02-26 18:55:10 -0800 Arun Persaud <arun@nubati.net>:
add information about our webpage and were to report bugs into the help menu


2012-02-26 18:40:27 -0800 Arun Persaud <arun@nubati.net>:
fixed "make install-pdf": missing target for recursive make in po directory


2012-02-26 23:06:33 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Suppress recent-engines menu items in ICS mode


2012-02-26 22:45:12 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix 50-move counter in ICS mode

Marking irreversible moves in the EP_STATUS did not work in ICS mode,
as ApplyMove,which did that is never executed there. Only the boards
sent by ICS are displayed,especially in observing mode. Now the status is
derived from the ICS mov strings (x in the SAN move, or P in the long move.

2012-02-26 17:18:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix two 64-bit warnings

Passing the engine number in a pointer variable to the callback needed
a two-step cast.

2012-02-26 16:53:24 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix piece symbols on switch back to variant normal

Variant switches were not properly detected, meaning the variable pieces
could keep a form belonging to a previous variant. (E.g. Queen remained
a Lance image after switching from shogi to normal.)

2012-02-26 14:07:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Keep XBoard windows attached on resize

Windows attached to bottom or right are displaced with the size increase.
Their perpendicular dimension is also scaled, to keep their edges at the same
fraction of the main window, unless they stick out. In the latter case the
fraction is clipped to 1, so that edge moves with the full size increase.

2012-02-25 22:40:56 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement -stickyWindows in XBoard

This makes the auxiliary windows  move with the main window when they were
touching, as in WinBoard. A control is added in the General Options dialog.

2012-02-25 21:14:03 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use more reliable X-call for getting window position

XtGetValues on XtNx, XtNy is unreliable. XGetWindowAttributes seems
to give more reliable results, and automatically accounts for the width
of window dressing. The -frameX/Y options are no longer needed bcause
of this, and were removed.

2012-02-25 11:55:19 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make frame width configurable in XB

New persistent options -frameX, -frameY now can be used to specify
the amount by which Xt lies about the window coordinates.

2012-02-23 20:01:55 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Use combobox line for recent engines when available

The entry made in the -recentEngineList for the startup engine was
derived from the -fcp value, but this would ignore a possible nickname.
In WinBoard we now use the full combobox line to derive the entry.

2012-02-23 09:29:17 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix translation of EngineOutputTitle WB


2012-02-23 01:34:12 +0100 Byrial Jensen <byrial@vip.cybercity.dk>:
Updated Danish translation


2012-02-23 00:59:36 +0100 Byrial Jensen <byrial@vip.cybercity.dk>:
One missed translation of cps->which


2012-02-22 19:58:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Undo translation of cps->which = first/second

The string in cps->which should not be translated, because it goes into
the debug file to label engine I/O, and many tools for processing
debug files (broadcasters, PGN extractors) rely on this being "first" or
"second". In all contexts where "first" and "second" need to be translated,
cps->which itself is already enclosed in _().

2012-02-22 18:27:40 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement -serverFile option

This writs an extra debug file with only engine communiation on it,
for the benifit of programs like TLCS.

2012-02-22 17:46:16 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement -autoCopyPV

This option causes automatic copying of the last position of a PV walk
to the clipboard.

2012-02-16 14:58:45 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Delete some load-game debug printing

The debug printing in Disambiguate was no longer needed. The printing
of the started process in XBoard that went to stderr is now diverted
to debugFP, so it ends up in the debug file.

2012-02-16 14:41:43 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Move change of debug file to before game load

Loading a game from -lgf is done before TwoMachinesEvent is called,
but logically belongs to the game. So the code to switch to the new
debug file for the game is moved to NextMatchGame now.

2012-02-16 14:09:54 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix button grab for sweep selection

The piece-menu initialization limited the grab of button events to those
occurring inside the board window (presumably intended to limit them to
the piece menu, but that does not pop up in sweep-selection mode).
This is now suppressed when -pieceMenu is off, so that selection continues
outside the the board. (Which is very convenient for pieces pu close to the
edge.)

2012-02-16 13:16:13 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Don't leave piece selected after piece menu

PieceMenuEvent left the just introduced piece selected, which is almost
never what one wants, as it makes it jump to the next square when selects.
Which is especially annoying if it captures the piece you wanted to grab...

2012-02-16 12:57:47 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix use of middle button for position setup

With sweep selection the actual drop is made on releasing the button,
and this event was not caught for button 2. Button-2 motion events were
also not caught by the sweep-selection handler.

2012-02-16 23:53:08 +0100 Byrial Jensen <byrial@vip.cybercity.dk>:
Fix one more typo in the translator comments explaning "first" and "second"


2012-02-16 23:39:32 +0100 Byrial Jensen <byrial@vip.cybercity.dk>:
Fix typo in translator comments explaning "first" and "second"


2012-02-16 23:23:20 +0100 Byrial Jensen <byrial@vip.cybercity.dk>:
Add args.h to POTFILES.in and change the interface to ExitArgError() so msg is c format string

Having msg as a format string will ease translations because then
badArg doesn't have to come last.

2012-02-16 22:51:44 +0100 Byrial Jensen <byrial@vip.cybercity.dk>:
Mark the strings "first" and "sencond" for translation.

... and assign the translated strings to cps->which in function InitEngine()

2012-02-16 18:42:10 +0100 Byrial Jensen <byrial@vip.cybercity.dk>:
Use ngettext() instead of gettext() for a string to allow better translation.


2012-02-16 00:19:59 -0800 Arun Persaud <arun@nubati.net>:
translation: updated uk.po


2012-02-15 20:59:09 -0800 Arun Persaud <arun@nubati.net>:
modified configure and makefile for handling mimedb update

the default configure will install them using the xdg commands (if they exist on the system)

2012-02-13 22:29:48 -0800 Arun Persaud <arun@nubati.net>:
add configure test for xdg-programs to install mime types; can be disabled for building of e.g. rpms

in case the target system doesn't have the xdg-programs available, we test for them.
Distributions often have their own macros to install these, so we add an enable option to configure

2012-02-13 22:05:26 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Remove a debug printf

The parsePV debug printf becomes extremely verbose with -fSAN, -sSAN,
so it was deleted.

2012-02-12 22:18:24 -0800 Arun Persaud <arun@nubati.net>:
new developer release


2012-02-12 22:19:37 -0800 Arun Persaud <arun@nubati.net>:
updated po/pot files


2012-02-12 22:17:03 -0800 Arun Persaud <arun@nubati.net>:
updated Changelog, NEWS, etc.


2012-02-12 07:52:54 -0800 Arun Persaud <arun@nubati.net>:
translation: updated uk.po


2012-02-12 11:38:30 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Leave height of row that only contains buttons free

All elements of the GenericPopUp are still scaled to the text height,
including buttons appended behind them (browse or color buttons).
But we now make an exception for a row that only contains buttons,
as there is no harm in it being a little higher (and the buttons look
prettier that way).

2012-02-12 00:01:24 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix OK button of error popup

The error dialog popped up as a child of the board window, even when
DisplayError was called from a dialog. Now it checks if a transient
dialog is up, and if so, it pops up as a child of that, grabs focus,
and suppresses the system popdown of the transient dialog through a flag
dialogError until it is popped down itself.

2012-02-11 20:07:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Update texi file


2012-02-11 10:18:02 -0800 Arun Persaud <arun@nubati.net>:
added some comments for translators


2012-02-11 10:08:46 -0800 Arun Persaud <arun@nubati.net>:
fixed comments for translators: comments starting with TRANSLATORS: are now copied to the po file


2012-02-11 19:01:49 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Also configure sweep selection

To make sure this feature is tested, we set -pieceMenu false in the
master settings file.

2012-02-11 18:26:34 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix date in copyright notice about-box


2012-02-11 17:15:11 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix switching animation masks on variant switch

The masks for variant-dependent piees (E,H in Seirawan, promoted Golds
in Shogi, the Gothic Chancellor) were no longer updated in InitDrawingSizes
because of the patch to reduce X-server calls.

2012-02-11 16:46:58 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Configure wider game list

The game list was by default too small, so that there was no room for the
filter field. Now a width of 500 is specified, whcih works at -size 49
as well as 72.

2012-02-11 16:29:06 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix button chaining and combo/textbox label height

Previous patches forgot to specify the height for the text labels on
-combo and -text options, so they were still too high. Buttons that go
on the same line as the previous element should be chained right, not rubber.

2012-02-11 15:52:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make -pgnNumberTag option setable from menu

The Save Options dialog now containes a checkbox for this.

2012-02-11 15:48:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Configure some new features switched on

The master settings file switches -showTargetSquares, -sweepPromotions
and -seekGraph on, so that they will get more testing.

2012-02-11 14:43:53 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix heigth of multi-line labels

The previous height patch overlooked that some labels are multi-line,
and need more height.

2012-02-11 14:10:21 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix popdown seekgraph on forward-event XB

Only the grid was drawn when the > or >> button were operated, because
a full redraw was not forced by ForwardInner. The recent patch to take
the seek graph down on such events did not account for that. (BackwardInner
always seems to do full redraw, however?)

2012-02-11 12:59:04 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Put front-end support for -recentEngines in XBoard

The engines are added to the menu. Problem is still that in XBoard
startup engines are given by command, rather than selected by combobox,
so the command rather than the nickname ends up in the menu. If this is
then selected, it cannot be found in the list. To limit the damage,
Fairy-Max is now pre-installed without nickname. -recentEngines is now
configured to 4.

2012-02-11 11:53:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Better solution to button-height problem

In stead of adapting the height of text widgets to that of buttons,
(as represented by the message widget), we now do the opposite, and
adapt the button & label heights. This is made safe by obtaining textHeight
from the fontSet's max_logical_extent, though an XExtendsFontSet() call.
Turns out the default height of text widgets is not exactly that, but
4 pixels larger for borders and margin.
  The parameter XtNvertDistance is now used to align the checkboxes with
the following text widget, and their size is derived from textHeight as
well.
  The XtNvertDistance is set to -1 for the lower spin button, so that it
its border coincides with that of the upper spin button. Their height is
set to textHeight/2. This makes their combined height just 1 pixel more
than that of the preceeding text widget. (Uh? 2 x tw/2 -1 > tw?), so for
other buttons we use that too (i.e. textHeight = font_extent + 5).

2012-02-10 22:39:08 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix warning

Deleting debug printing had made a variable unused.

2012-02-10 22:26:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix sleeping bug

The text-edit-height patch introduced a bug that did not have any consquences
(yet), as the extra arg erroneously included leftover from a previous
SetValues call happened to be the same as one of the intended args.

2012-02-10 20:51:41 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix unloading of first engine on tourney start

Because NextTourneyGame was loading a new engine before ReserveGame was
called to unload it with dummy game nr = -1), the first engine proc kept
hanging.

2012-02-10 18:39:09 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Remove some of the most verbose debug output


2012-02-10 17:46:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Delete some unused WinBoard bitmaps

There waere up-side-down knight icons that apparently hid by mistake
in the bitmaps directory: they were not part of WinBoard

2012-02-10 17:39:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Cosmetic: change 4.5 to 4.6 in xboard.conf comment


2012-02-10 17:35:22 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix crash on empty combobox menu XB

XBoard crashed when a combobox without items was opened, as could easily
happen in the Load Engine dialogs when -firstChessProgramNames contained
no items, as it would without configuring. Now the creation of the popup
menu is suppressed in that case.

2012-02-10 17:13:36 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix position of checkbox XB

With the large height the widget get in internationalization, the
checkboxes are position way too high above the text. To shift them down
a dummy borderless label widget is drawn above them (when needed).

2012-02-10 15:07:35 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix heights in Engine Output window XB

The icons did not fit in the space above the memos anymore, so the height
of this area is now left free.

2012-02-10 14:55:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Derive height of text-edits in dialogs from message widget

With internationalization the default height of buttons has inexpliquably
inreased compared to that of text-edits, messing up the layout of the
GenericPopUp. The message widget is now used as a emasure of how high
the widgets should be.

2012-02-10 14:21:37 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Configure XBoard engines and textures

The new -useBoardTexture option is needed in xboard.conf, as we want to
distribute with the texture on, while the compiled-in default is off.
A list of 4 engines has been configured (fairymax, fruit, crafty, gnuchess),
as the Load Engine and Match Options checkboxes crash XBoard when the list
is empty. The -recentEngines option is set to 0 to make sure the code
associated with it is never executed: the code is still experimental,
and the required front-end support is only present in WinBoard anyway.

2012-02-10 13:30:58 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Update Dutch WinBoard translation


2012-02-10 13:18:48 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Create room in some WB dialogs for translations


2012-02-10 13:17:30 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Add 5 missing strings to WinBoard translation template


2012-02-09 23:03:58 -0800 Arun Persaud <arun@nubati.net>:
new developer release


2012-02-09 23:04:46 -0800 Arun Persaud <arun@nubati.net>:
updated po-filies


2012-02-09 22:59:05 -0800 Arun Persaud <arun@nubati.net>:
updated Changelog, NEWS, etc.

2012-02-09 22:44:39 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix non-bug in WinBoard

The IDM_RecentEngines was not used in symbolic form everywhere.

2012-02-09 18:46:08 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix MAXENGINES in WinBoard

The front-end arrays for expanding the engine list measured 1000 entries,
in stead of MAXENGINES, leading them to overflow.

2012-02-09 13:05:42 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement kludge to set options through Move Type-in

A leading "!!! " will cause the rest of the line to be parsed as
command line. Very dangerous, as an unknown option (e.g. because of a typo)
will cause a fatal error, which makes XBoard exit.

2012-02-09 13:04:44 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Put move number in Eval Graph title


2012-02-09 13:00:09 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement -pgnNumberTag option

A new (persistent) boolean option controls if the sequence number is to
be written in saved tourney games as a Number tag, to make it easier
to correlate games with debug files.

2012-02-09 12:55:52 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Create separate debug fil for each tourney game

Users can now apecify a -debugfile with %d in its name, and this will
be replaced by the sequence number of the game. TwoMachinesEvent then
starts by opening a new file when the name has changed, so that each
game will go to a different file, with recognizable name.

2012-02-09 12:51:25 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix bug in WB combobox readout

The previous patch exposed a latent bug in the readout of the generic popup.

2012-02-08 23:25:31 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Allow grouping of engines in engine list

Lines "# GROUPNAME" and "# end" enclose a group in -firstChessProgramNames.

2012-02-08 17:47:46 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix TidyProgramName

A trailing .exe was not removed if the engine name was quoted.

2012-02-08 17:45:42 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Put recently used engines in WB menu

A new option -recentEngines specifies how many engines should be listed.
The list of nicknames is stored in the ettings file as -recentEngineList.
The engines are appended to the Engine menu.

2012-02-04 19:37:51 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix registering of EditTagsProg

This was registered with X as EditCommentProc!

2012-02-07 23:04:49 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Increase max nr of engines to 2000

Move the #define for MAXENGINES also to common.h, so that both the
Load and Tourney dialog use the same maximum.

2012-01-19 23:01:20 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix fix of switch to mono-mode

The previous fix had == in stead of != for testing if mono-mode had changed.

2012-01-19 22:21:38 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Make New Variant dialog visible in mono-mode

All colored buttons did get a black background, and also black text...
Use timer background color in stead, which is white.

2012-01-19 20:48:37 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Incease size of WB array of translated items

For the BoardOptions dialog 42 items are now needed

2012-01-19 17:18:25 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement Clone Tourney button XBoard

This makes use of the new GenericUpdate().

2012-01-19 16:34:13 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Implement GenericUpdate function

This does the opposite from GenericReadout: it copies the current
parameter values into the dialog.

2012-01-19 12:19:27 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix arrow damage with highlightDragging XB

With highlight dragging the highlights of the previous moves are cleared
when lifting the piece. Logically, this should also clear the arrow, but
to do that requires a board redraw, which is not done at this stage. (And
even then this would only be effective after marking the arrow damage,
which is not done yet either). As a temporary fix, we repair the arrow
by redrawing it.
  This patch has moved marking of the arrow damage from DrawArrowHighlight
to a separate routine, so a future better fix can also call that when the
arrow should be erased.

2012-01-18 16:01:50 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Prevent unnecessary loading of engines

For engines that can be reused, the unloading at the end of a pairing
is in some cases wasteful, as the same engine will be used in the next
pairing as well. In simple gauntlets the gauntlet engine will always
stay first engine, while in multi-gauntlets the oppent engine will stay
the same for an entire round. In these cases unloading is now suppressed.

2012-01-17 22:22:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Reset protocol version before loading new engine

The protocol version was not reset, so if the previous engine was v1,
the newly loaded engine would not be sent a protover command, so
that its features would remain unknown!

2012-01-17 19:33:32 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Give focus to board window after ICS login

toprevent that the focus remains on any popped up chat boxes, it is
explicitlly set otherwise. The board window is preferred over the
ICS interaction window, because you can type from there to the ICS anyway,
and it makes all accelerator keys available.

2012-01-16 14:37:05 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Fix seek-graph popup and  popdown

Clicking outside the board area in WB (e.g.on the clocks) would also
trigger seek-graph 'popup'. This is now suppressed by testing for
y-coord > 0. In addition, the seek graph is automaticaly taken down
when we step to another position in the current game (using buttons,
arrow keys or whatever).

2012-01-15 21:29:11 +0100 H.G. Muller <h.g.muller@hccnet.nl>:
Suppress empty lines when observing on VICS

Capture of the engine kibitzes when observing an engine game with

Clicking on the clock in WinBoard also called the LeftClick routine

A few (dangerous) options are added to allow a user to override
engine features, or change their defaults, by supplying a string
with feature commands (e.g. "sigint=0") which tricks XBoard into
thinking the engine sent that. There is a -featureDefaults which is
processed before the engine features, and -first/secondFeatures
which is parsed just before engine initialization.
  This goes horribly wrong when the user wouldtry silly things like
including 'option' or 'done' features!

Fix duplicate loading of second engine in tourneys

To decide if new engines should be loaded, it was tested if first.pr
equalled NoProc, assuming that ReserveGame would have left the engine
loaded if the next game would need the same engines. But a reuse=0 engine
could have caused termination of the first engine process anyway, while
the second would still be alive. So unconditionally starting of the second
engine would cause redundant engine processes to abound.
  Now we only start new engine processes if both engine processes are dead.

This boolean option determines the default setting of the hasOwnBook

on the engine install line can still overrule this, though.
 A control to set this option has been added in the XBoard Match dialog,

Fix display state after failed analysis attempt

When an engine responded to the "analyze" command with an "unknown command"
message, a Reset was done without altering the display, causing a
discrepancy between display and internal state, which caused confusion
when it finally corrected itself. I replaced the Reset call by an
EditGameEvent call, to preserve the loaded game. The Reset was presumably
used to allow for the case where the engine would be so upset by the
analyze command that it needed to be reset by a "new" command, but this
seems overly paranoic for an engine that just recognized the command
as an unknown one.

Implement searching games in Game List for a position

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

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

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

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

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

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

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

Give WinBoard Game List its own font

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

A right down-click starting a sweep-selection event did not grab the

routine we request the grab.

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

Let -sweepPromotions also work for click-click moves

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

The markers on move targets are now kept when a first click merely

Fix drop moves on boards with more than 10 ranks

The internal encoding for rank 16 is '@', and thus ambiguous with drop
moves. They were always printed as 16, breaking drop games on large

by checking if the preceeding letter is upper case, in which case it
cannot be a fileindicator, but must be a piece, and thus a drop.

Implement Grand Chess

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

Increase efficiency of SAN generation / disambiguation

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

Cure flicker in Move History window, fix highlighting

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

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

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

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

Fix concurrency in Swiss tourneys

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

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

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

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

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

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

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

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

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

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

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

Fix display of international characters outside the ASCII range.

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

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

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

Make engine startup failure non-fatal in WinBoard

Unlike XBoard, which forks first, the parent process WinBoard has direct
knowledge of a failure to execute the engine command, and used it to

action is taken to 'bury' the deceased engine process. Like in XBoard,

Plug memory leak, filenames relative to installDir

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

Improve sizing of comment and tags dialogs

There seems to be a bug in Xaw for the sizing of buttons; they get
unpredicatble and weird sizes when the size is not explicitly set,

buttons overlapand text edits shrink to almost nothing. To prevent that
we now define exlicit sizes for the buttons in tags and comment popups.

Fix PV walking in analysis mode

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

All string options should now point to allocated memory, as strdup /

initialize those.

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

harmful), and could be combined. In stead of determining the load index
incrementally, it is now calculated in an absolute way from the game
number, so it can be used more easily in tournament mode.

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

A "Load Engine ..." menu item is added to the Engine menu, which pops
up a dialog where one can replace the first or second engine by a new

re-enabling clockMode. It was also important that noChessProgram is
cleared before re-initializing the ChessProgramState.
  The Load-Engine dialog can select from the list of installed
engines, and also add a newly specified engine to this list. In this
case it saves the directory, hasBook, and isUCI info with the engine,
and optionally the current variant. When loading an engine with a
specified variant, it resets the game and switches to the new variant.

Fix sweep-promotions patch

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

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

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

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.

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

Let file browser filter on extension

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

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

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

Redo ICS input box with generic popup

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

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).

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.

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).

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.

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.

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.
