NAME
hoichess - xboard compatible chess engine
hoixiangqi - xiangqi engine
SYNOPSIS
hoichess [options]
hoixiangqi [options]
DESCRIPTION
hoichess is a chess playing program. It implements major parts of the
xboard/winboard chess engine protocol.
hoichess uses many of the standard techniques found in modern chess
programs, like rotated bitboards, principal variation search,
quiescence search, transposition table and iterative deepening.
See xboard(6) for instructions about how to use hoichess through
xboard. To start up quickly, you just need the command: xboard -fcp
hoichess.
hoixiangqi is a xiangqi ("Chinese chess") playing program. Recent
versions of xboard also support xiangqi: xboard -fcp hoixiangqi.
hoichess and hoixiangqi are built from the same code base, so nearly
all commands and options, as well as the text based user interface, are
the same for both programs.
If run hoichess or hoixiangqi at the command line, the help command
gives you a brief summary of available commands.
At program start, a default startup file is read. This file is called
hoichess.rc or hoixiangqi.rc, respectively. It is searched for in the
following directories, in order: current directory, $HOME/.hoichess,
$USERPROFILE/.hoichess (only on Windows), DATADIR. Only the first
found file is read. The DATADIR is installation dependent, commonly
/usr/share/games/hoichess.
OPTIONS
-h, --help
Display usage information.
-V, --version
Display version information.
-v, --verbose[=n]
Increase verbosity. Multiple -v options may be given.
--verbose=n sets verbosity level n.
-d, --debug[=n]
Increase debug level. Multiple -d options may be given.
--debug=n sets debug level n.
-x, --xboard[=arg]
Start in xboard compatible mode. This turns off the input
prompt and alters the output format to meet the requirements of
the xboard protocol. Normally, this option should not be
necessary because hoichess automatically detects when it is
started under xboard.
The optional argument can be one of:
off Force non-xboard mode.
on Force xboard mode.
--source filename
Before accepting input from stdin, first read commands (and
probably moves) from filename. Can be given multiple times.
--initcmd command
Execute command at startup. The command is executed before
reading script files given by the --source option. Can be given
multiple times.
--norc Do not read default startup file hoichess.rc or hoixiangqi.rc.
--color arg
Control usage of ANSI color control sequences, e.g. when
displaying the chess board.
arg can be one of:
off Never use ANSI color sequences.
on Always use ANSI color sequences.
auto
Automatically use ANSI color sequences when stdout is a
terminal.
On Unix platforms, the default is auto. On Windows platforms,
the default is off, because the Windows terminal is normally
not ANSI capable.
