WinBoard/XBoard 4.8.0 released

Post by hgm » Sat Oct 18, 2014 10:27 pm

I prepared a binary installer for WinBoard 4.8.0. I haven't announced it at WB forum yet, but will update the download pages there shortly. The installer is already downloadable from http://hgm.nubati.net/WinBoard-4.8.0.exe .

Main new features that would benefit Chess users are:
* tablebase hits, selective depth and nps can be shown in Engine Output.
* Clicking moves in the Edit Book window plays them, and moves can be added to the book by playing them.
* The Evaluation Graph can be switched to differential mode ('Blunder Graph').
* Bulk saving of all selected games from a PGN database is possible, to create a new one.
* Setting up positions is made much easier by providing a 'pallette' board showing every piece once, and having a copy as well as move function for the pieces.
* The possibility to cut short engine-engine games based on scorpio bitbase probing.
* The clock times are saved as PGN comment in unfinished games, and restored when they are reloaded, making it easier to adjourn games.

The package contains a new Polyglot (2.0.2) that is needed for transmitting the tablebase hits of UCI engines. (It has a new option ShowTbHits.) It also contains a new Fairy-Max (4.8U), which supports four new variants, amongst which 'King of the Hill' and 'Charge of the Light Brigade', using the new WinBoard mechanism for engine-defined variants. General variant support of WinBoard has been greatly improved with this version; basically completely unknown variants now work just as smoothly as standard variants, because the engine can tell XBoard the rules. The new Fairy-Max uses this to improve the handling of all its existing variants that formerly had to be played with legality testing off. (E.g. Cylinder Chess.) The included Shokidoki engine now also supports Tori Shogi, which also makes use of this facility.

For XBoard there are additional new features:
* The GTK build is declared stable.
* An ICS Interaction window similar to WinBoard's, with integrated chat boxes.
* A Board Theme dialog to create and recal themes.
* More flexible use of fonts (in the GTK version).
* Automatic install of engines that comply with the plugin standard.

The XBoard source code is available from the GNU Savannah git repository. (I am not sure there are prepared tar balls yet.)

Thanks to the efforts of Joshua Pettus there also is an OS X App for XBoard available, for running on a Mac with a native feel. This will also be distributed from WB forum:

Hmm, they all end in 'Score'. I wonder if that can have something to do with it.

Sounds like you did not install it.

The other messages are normal, if you upgrade from something older than 4.6, as the -pixmapDirectory option is no longer supported, and it would still be in your settings file. (In fact pixmaps are no longer supported since we switched to the Cairo plot library.) This is not fatal, though, just a warning, and after you saved settings once it should disappear.

Having no pieces at all to display is fatal, though.

I tried changing RepetitionScore to RepetitionValue, still the same result, the option is not displayed.
What about a spin type with negative values?

I also don't see them in the Engine Settings dialog.

Problem is that I also don't see them when I run Deuterium as UCI engine in the console:

Apparently the Deuterium that has them is not available for download yet. Which makes it kind of hard for me to test/debug...

OK, I already added an option RepetitionScore to Fairy-Max, ranging from -100 to 100.

The control did not show up in the Settings dialog, but space was reserved from it, and the standard debug output written to the debug file that shows how the dialog ahould look, prints the option.

But there is something very fishy going on. I added a print statement in the WinBoard backend at the point where the option is received from the engine, to print what was parsed. This prints the correct values (0, -100 and 100), so nothing wrong there. But then the problem in the front-end disappears! The option is displayed as it should.

OK, found it and fixed it.

Apparently two lines of code got commented out to silence a warning. (Funny thing is that I did not get a warning after uncommenting them.)

The lines were commented out without much thinking, because they would only be active on -slider options, which WinBoard does not support yet internally. (It immediately maps them onto -spin.)

Unfortunately that they referred to Slider was a bug in itself. I had used a kludge to change the option type Spin to Spin+100 for indicating -spin options that could attain negative values. Because these need non-numeric control, as Windows does not allow you to type a minus sign in numeric controls. So a switch statement that originally had a "case Spin:" now also needed a duplicate "case Spin+100:", and inadvertantly I made that by duplicating the "case Slider:" instead, and adding +100 to that. This probably happened when I tried to transfer the fix for not accepting the minus sign after making and testing it on Windows to the git repository on Linux, by just typing it by hand.


Anyway, I fixed it now, and put the resulting "WinBoard 4.8.0a" binary in the installer, at the same download link.
