@cindex dropMenu, option
This option allows you to emulate old behavior,
Analyze mode by holding the Shift key down while entering a move.
When it is off, the Shift key will be ignored.
Default: False.
+@item -appendPV true|false
+@cindex appendPV, option
+When this option is on, right-clicking a PV in the Engine Output window
+will play the first move of that PV in Analyze mode,
+or as many moves as you walk through by moving the mouse.
+Default: False.
@item -absoluteAnalysisScores true|false
@cindex absoluteAnalysisScores, option
When true, scores on the Engine Output window during analysis
If this option is true, XBoard acts as a passive chessboard; it
does not start a chess engine at all. Turning on this option
also turns off clockMode. Default: false.
+@item -viewer
+@itemx -viewerOptions string
+@cindex viewer, option
+@cindex viewerOptions, option
+Presence of the volatile option @code{viewer} on the command line
+will cause the value of the persistent option @code{viewerOptions}
+as stored in the settings file to be appended to the command line.
+The @code{view} option will be used by desktop associations with
+game or position file types, so that @code{viewerOptions} can be
+used to configure the exact mode XBoard will start in when it
+should act on such a file (e.g. in -ncp mode, or analyzing
+with your favorite engine). The options are also automatically
+appended when Board is invoked with a single argument not being
+an option name, which is then assumed to be the name of a
+@code{loadGameFile} or (when the name ends in .fen) a
+@code{loadPositionFile}.
+Default: "-ncp -engineOutputUp false -saveSettingsOnExit false".
+@item -tourneyOptions string
+@cindex tourneyOptions, option
+When XBoard is invoked with a single argument that is a file
+with .trn extension, it will assume this argument to be the value
+of a @code{tourneyFile} option,
+and apped the value of the persistent option @code{tourneyOptions}
+as stored in the settings file to the command line.
+Thus the value of @code{tourneyOptions} can be
+used to configure XBoard to automatically start running a
+tournament when it should act on such a file.
+Default: "-ncp -mm -saveSettingsOnExit false".
@item -mode or -initialMode modename
@cindex mode, option
@cindex initalMode, option
@cindex nameOfDebugFile, option
Sets the name of the file to which XBoard saves debug information
(including all communication to and from the engines).
+A @kbd{%d} in the given file name (e.g. game%d.debug) will be replaced
+by the unique sequence number of a tournament game,
+so that the debug output of each game will be written on a separate file.
@item -engineDebugOutput number
@cindex engineDebugOutput, option
Specifies how XBoard should handle unsolicited output from the engine,
xboard -ics -icshost firewall.example.com -icsport 23
@end example
@noindent
-Or in your @file{.Xresources} file:
-
-@example
-XBoard*internetChessServerHost: firewall.example.com
-XBoard*internetChessServerPort: 23
-@end example
-@noindent
Then when you run XBoard in ICS mode, you will be prompted
to log in to the firewall host. This works because port 23 is the
standard telnet login service. Do so, then telnet to ICS, using a
@end example
@noindent
-Or in your @file{.Xresources} file:
-
-@example
-XBoard*gateway: rsh.example.com
-XBoard*internetChessServerHost: chessclub.com
-@end example
-
Then when you run XBoard in ICS mode, it will connect to
the ICS by using @file{rsh} to run the command
@samp{telnet chessclub.com 5000} on host @samp{rsh.example.com}.
@end example
@noindent
-Or in your @file{.Xresources} file:
-
-@example
-XBoard*useTelnet: true
-XBoard*telnetProgram: ptelnet
-@end example
-
-@noindent
Then when you run XBoard in ICS mode, it will issue the
command @samp{ptelnet chessclub.com 5000} to connect to the ICS.
that is, your @file{ptelnet} program doesn't let you connect to
alternative ports. As noted above, your chess server may allow you to
connect on port 23 instead. In that case, just add the option
-@samp{-icsport ""} to the above command, or add
-@samp{XBoard*internetChessServerPort:} to your @file{.Xresources} file.
+@samp{-icsport ""} to the above command.
But if your chess server doesn't let you connect on port 23, you will have
to find some other host outside the firewall and hop through it. For
instance, suppose you have a shell account at @samp{foo.edu}. Set
@end example
@noindent
-Or in your @file{.Xresources} file:
-
-@example
-XBoard*useTelnet: true
-XBoard*telnetProgram: ptelnet
-XBoard*internetChessServerHost: foo.edu
-XBoard*internetChessServerPort:
-@end example
-
-@noindent
Then when you run XBoard in ICS mode, it will issue the
command @samp{ptelnet foo.edu} to connect to your account at
@samp{foo.edu}. Log in there, then type @samp{telnet chessclub.com 5000}.
@example
xboard -pixmap ~/fritz4
