This section describes how to run the “xshogi” program.
xshogi [ options ]
xshogi provides an X11/Xt/Athena Widgets user interface for gnushogi. With xshogi you can play gnushogi, set up arbitrary positions, force variations, or watch xshogi manage a game between two shogi programs. Furthermore, it can be used as an interface between two players on different displays.
xshogi can also be used as a shogi board 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.
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, gnushogi will not allow it. xshogi will then retract the move.
The following command line options also correspond to X resources that you can set in your .Xdefaults file.
xshogi accepts standard Xt options like -display, -geometry, and -iconic.
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.
Number of moves in a time control period. Default: 40 moves.
Tell gnushogi to spend at most the given amount of time searching for each of its moves. Without this option, gnushogi 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.
Tell gnushogi to look ahead at most the given number of moves when searching for a move to make. Without this option, gnushogi 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.
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.
Time delay between moves during “Load Game”. This doesn’t have to be a round number. Try -td 0.4. Default: 1 second.
If this option is True, xshogi acts as a passive shogi board; 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.
Name of first shogi program. In matches between two machines, this program plays white. Default: “gnushogi”.
Name of second shogi program, if needed. In matches between two machines, this program plays black; otherwise it is not started. Default: “gnushogi”.
Name of host the first shogi program plays on. Default: “localhost”.
Name of host the second shogi program plays on. Default: “localhost”.
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.
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”.
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 /.
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 /.
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 /.
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 /.
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.
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.
Color specification for pieces suitable for XParseColor(). Default: #FFFFD7.
Same for squares. Default: #EBDFB0.
Choose the Western style piece set.
Names of the bitmap files for the bitmap piece icons.
Names of the bitmap files for the outline piece icons.
Turns on debugging printout.
OTHER X RESOURCES
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 gnushogi to randomize its move selection slightly so that it doesn’t play the same moves in every game. Even without “random”, gnushogi randomizes its choice of moves from its opening book. You can also remove “easy” if you like; including it toggles easy mode off, causing gnushogi 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 gnushogi documentation (see gnushogi) for details.
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 gnushogi.
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:
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:
The font used for coordinates (when the showCoords option is True) can be set similarly:
If you are using a grayscale monitor, try setting the colors to:
COMMAND BUTTONS AND KEYS
Quits xshogi. Q or q is a keyboard equivalent.
Resets xshogi to the beginning of a shogi game. It also deselects any game or position files.
inverts the view of the shogi board.
displays a move hint from gnushogi.
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.
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.
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 whether 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 gnushogi text bookfiles.
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.
forces gnushogi to play white.
forces gnushogi to play black.
forces a series of moves. That is, gnushogi stops playing and xshogi allows you to make moves for both white and black.
plays a game between two computer programs.
moves forward through a series of remembered moves. F or f is a keyboard equivalent.
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.
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.
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.
allows you to make a two display game between two human players. Enter the display you want to connect to. If you are allowed to connect, a new board is displayed at the remote display. Challenge mode can only be stopped by pressing “quit”.
allows you to reset the clocks for both players. Enter the number of moves and the number of minutes in which the moves should be done.
force computer to stop thinking and to make the current best move.
If you press the Pause button during GNU Shogi’s turn, xshogi will stop the clocks, but gnushogi will still make a move.
After a mate or draw when playing against gnushogi, if you back up with the Backward button, the clocks are reset (because gnushogi has exited and must be restarted).
The game parser recognizes only algebraic notation.
