NAME

xshogi - Xt/Athena user interface for GNU Shogi, version 1.0  

SYNOPSIS

xshogi [ options ]  

DESCRIPTION

xshogi provides an X11/Xt/Athena Widgets user interface for GNU Shogi. With xshogi you can play GNU Shogi, set up arbitrary positions, force variations, or watch xshogi manage a game between two shogi programs.

xshogi can also be used as a shogiboard to play out games. It will read through a game file or allow a player to play through a variation manually (force mode). This is useful for keeping track of email postal games or browsing games off the net. You can use xshogi in this way even if you don't have GNU Shogi.

After starting xshogi, you can make moves by pressing mouse button 1 while the cursor is over a square with your piece on it and dragging the mouse to another square. If the move is illegal, GNU Shogi will not allow it. xshogi will then retract the move.  

OPTIONS

The following command line options also correspond to X resources that you can set in your .Xdefaults file.
standard Xt options
xshogi accepts standard Xt options like -display, -geometry, and -iconic.
-tc or -timeControl minutes[:seconds]
Amount of time for a set of moves determined by movesPerSession. If this number of moves is played within the time control period, xshogi resets the time clocks. Default: 5 minutes.
-mps or -movesPerSession moves
Number of moves in a time control period. Default: 40 moves.
-st or -searchTime minutes[:seconds]
Tell GNU Shogi to spend at most the given amount of time searching for each of its moves. Without this option, GNU Shogi chooses its search time based on the number of moves and amount of time remaining until the next time control. Setting this option also sets -clockMode to False.
-sd or -searchDepth number
Tell GNU Shogi to look ahead at most the given number of moves when searching for a move to make. Without this option, GNU Shogi chooses its search depth based on the number of moves and amount of time remaining until the next time control. Setting this option also sets -clockMode to False.
-clock or -clockMode (True | False)
Determines whether or not to use the clock. If clockMode is False, the clock does not run, but the side that is to play next is still highlighted.
-td or -timeDelay seconds
Time delay between moves during "Load Game". This doesn't have to be round numbers. Try -td 0.4. Default: 1 second.
-ncp or -noShogiProgram (True | False)
If this option is True, xshogi acts as a passive shogiboard; it does not try to start a shogi program, not even to check whether moves made in Force mode are legal. It also sets -clockMode to False. Default: False.
-fcp or -firstShogiProgram program
Name of first shogi program. In matches between two machines, this program plays white. Default: "gnushogix".
-scp or -secondShogiProgram program
Name of second shogi program, if needed. In matches between two machines, this program plays black; otherwise it is not started. Default: "gnushogix".
-fh or -firstHost host
Name of host the first shogi program plays on. Default: "localhost".
-sh or -secondHost host
Name of host the second shogi program plays on. Default: "localhost".
-rsh or -remoteShell shell_name
Some systems do not use rsh as the remote shell. This option allows a user to name the remote shell command. This should be done in the resource file.
-mm or -matchMode (False | Init | Position | Opening)
Automatically run a game between firstShogiProgram and secondShogiProgram. If matchMode is set to Init, xshogi will start the game with the initial shogi position. If matchMode is set to Position, xshogi will start the game with the position specified by the loadPositionFile resource. If matchMode is set to Opening, xshogi will play out the opening moves specified by the -loadGameFile resource. If the -saveGameFile resource is set, a move record for the match will be saved in the specified file. Default: "False".
-lgf or -loadGameFile file
Name of file to read a game record from. Game files are found in the directory named by the SHOGIDIR environment variable. If this variable is not set, the current directory is used unless the file name starts with a /.
-lpf or -loadPositionFile file
Name of file to read a game position from. Position files are found in the directory named by the SHOGIDIR environment variable. If this variable is not set, the current directory is used unless the file name starts with a /.
-sgf or -saveGameFile file
Name of file to save a game record to. Game files are saved in the directory named by the SHOGIDIR environment variable. If this variable is not set, the current directory is used unless the file name starts with a /.
-spf or -savePositionFile file
Name of file to save a game position to. Position files are saved in the directory named by the SHOGIDIR environment variable. If this variable is not set, the current directory is used unless the file name starts with a /.
-coords or -showCoords (True | False)
If this option is True, xshogi displays algebraic coordinates along the board's left and bottom edges. The default is False. The coordFont resource specifies what font to use.
-mono or -monoMode (True | False)
Determines whether xshogi displays its pieces and squares with two colors or four. You shouldn't have to specify monochrome. xshogi will determine if this is necessary.
-wpc or -blackPieceColor color
Color specification for black pieces suitable for XParseColor(3X11). Default: #FFFFCC. These colors look good on a DEC workstation. If you need different colors, try using the xcolors application. Source for xcolors can be found in the X11/R4 contrib directory.
-bpc or -whitePieceColor color
Same for white pieces. Default: #202020.
-lsc or -lightSquareColor color
Same for light squares. Default: #C8C365.
-dsc or -darkSquareColor color
Same for dark squares. Default: #77A26D.
-npb or -normalPawnBitmap file
-nnb or -normalKnightBitmap file
-nbb or -normalBishopBitmap file
-nrb or -normalRookBitmap file
-nkb or -normalKingBitmap file
Names of the bitmap files for the bitmap piece icons.

-rpb or -reversePawnBitmap file
-rnb or -reverseKnightBitmap file
-rbb or -reverseBishopBitmap file
-rrb or -reverseRookBitmap file
-rkb or -reverseKingBitmap file
Names of the bitmap files for the outline piece icons.
-debug or -debugMode (True | False)
Turns on debugging printout.
 

RESOURCES

initString
The actual string that is sent to initialize the shogi program can be set from .Xdefaults. It can't be set from the command line because of syntax problems. The default value is "new\nbeep\nrandom\neasy\n". The "new" and "beep" commands are required. You can remove the "random" command if you like; including it causes GNU Shogi to randomize its move selection slightly so that it doesn't play the same moves in every game. Even without "random", GNU Shogi randomizes its choice of moves from its opening book. You can also remove "easy" if you like; including it toggles easy mode off, causing GNU Shogi to think on your time. That is, if "easy" is included in the initString, GNU Shogi thinks on your time; if not, it does not. (Yes, this does seem backwards, doesn't it.) You can also try adding other commands to the initString; see the GNU Shogi documentation for details.
blackString and whiteString
These resources control what is sent when the Machine Black and Machine White buttons are selected. This is mostly for compatibility with obsolete versions of GNU Shogi.

Alternate bitmaps for piece icons can be specified either by choosing one of the built-in sets or with the file name resources described above. There are three built-in sets of piece bitmaps available, large (the default), medium, or small. It is easiest to select the set you prefer in the .Xdefaults file:


XShogi*boardSize:      Medium

The font used for button labels and comments can be changed in the .Xdefaults file. You may want to choose a smaller font if you are using the small pieces:


XShogi*font:   helvetica_oblique12

The font used for coordinates (when the showCoords option is True) can be set similarly:


XShogi*coordFont: helvetica_10

If you are using a grayscale monitor, try setting the colors to:


XShogi*blackPieceColor: gray100
XShogi*whitePieceColor: gray0
XShogi*lightSquareColor: gray60
XShogi*darkSquareColor: gray40  

COMMAND BUTTONS AND KEYS

Quit
Quits xshogi. Q or q is a keyboard equivalent.
Reset
Resets xshogi to the beginning of a shogi game. It also deselects any game or position files.
Flip View
inverts the view of the shogi board.
Hint
displays a move hint from GNU Shogi.
Load Game
plays a game from a record file. If no file is specified a popup dialog asks for a filename. Game files are found in the directory named by the SHOGIDIR environment variable. If this variable is not declared then the current directory is used unless the file name starts with a /. G or g is a keyboard equivalent. The game file parser will accept almost any file that contains moves in algebraic notation. If the first line begins with `#', it is assumed to be a title and is displayed. Text enclosed in parentheses or square brackets is assumed to be commentary and is displayed in a pop-up window. Any other text in the file is ignored.
Load Position
sets up a position from a position file. If no file is specified a popup dialog asks for a filename. Position files are found in the directory named by the SHOGIDIR environment variable. If this variable is not declared then the current directory is used unless the file name starts with a /. Position files must be in the format that the Save Position command writes.
Save Game
saves a game to a record file. If no file is specified a popup dialog asks for a filename. If the filename exists, the user is asked wether the current game record is be appended to this file or if the file should be replaced. Game files are saved in the directory named by the SHOGIDIR environment variable. If this variable is not declared then the current directory is used unless the file name starts with a /. Game files are human-readable, and can also be read back by the Load Game command. Furthermore, they are accepted as GNU Shogi text bookfiles.
Save Position
saves a position to a position file. If no file is specified a popup dialog asks for a filename. Position files are saved in the directory named by the SHOGIDIR environment variable. If this variable is not declared then the current directory is used unless the file name starts with a /. Position files are human-readable, and can also be read back by the Load Position command.
Machine White
forces GNU Shogi to play white.
Machine Black
forces GNU Shogi to play black.
Force Moves
forces a series of moves. That is, GNU Shogi stops playing and xshogi allows you to make moves for both white and black.
Two Machines
plays a game between two computer programs.
Forward
moves forward through a series of remembered moves. F or f is a keyboard equivalent.
Backward
moves backward through a series of remembered moves. As a side effect, puts xshogi into Force Moves mode. B or b is a keyboard equivalent.
Pause
pauses the clocks or (in Load Game mode) pauses the game being loaded. Press Pause again to continue. P or p is a keyboard equivalent.
Edit Position
lets you set up an arbitrary board position. Use mouse button 1 to drag pieces to new squares, or to delete a piece by dragging it off the board or dragging an empty square on top of it. To drop a new piece on a square, press mouse button 2 or 3 over the square. This brings up a menu of black pieces (button 2) or white pieces (button 3). Additional menu choices let you empty the square or clear the board. You can set the side to play next by clicking on the Black or White indicator at the top of the screen.
Iconify
I, i, C or c iconifies xshogi.

LIMITATIONS

If you press the Pause button during GNU Shogi's turn, xshogi will stop the clocks, but GNU Shogi will still make a move.

After a mate or draw when playing against GNU Shogi, if you back up with the Backward button, the clocks are reset (because GNU Shogi has exited and must be restarted).

Some xshogi functions may not work with versions of GNU Shogi earlier than 4.0, patchlevel 52. In particular, with GNU Shogi 3.1 the -timeControl resource can be given only to the nearest minute, and restoring a saved position with white to play may not work.

The game parser recognizes only algebraic notation.
