NAME
chessfs - chess filesystem
SYNOPSIS
chessfs [-verbose] [-addr addr] [-srv srv] [-group gid]
DESCRIPTION
Chessfs is a filesystem for playing chess games. It posts a
server named after the argument, which by default is
"chessfs". Specifying a listening address serves 9p over
the announces address, instead of a server, or UNIX socket.
The files' username is the one running the program, and the
group can be set using the -group option.
The filesystem contains three files - ctl, clone and games.
Opening the clone file creates a new game, and the id can be
read from the fid. The game can be found under the games
directory, as a directory with the game id. Ctl is for
reading and setting server options. It displays the maximum
amount of games, and the current count of games. Setting
roomsize changes the maximum number of games which can be
played.
In each game directory, there are the ctl, white, black and
moves file. Ctl supports the following commands:
time seconds Set the amount of time each player has. The
default value is -1 indicating that the game
is not timed.
start Start the game.
close Close the game, which may or may not have
ended.
The board files, white and black, show the current pieces'
position, depending on the player. Writing to the file makes
a move on behalf of the specified player.
draw Offer a draw, or accept a draw if the other player
offered one.
resign Resign the game.
move Make the following move, following the algebraic
notation.
EXAMPLES
Run the filesystem:
chessfs -srv chessfs -group chessclub
mount /srv/chessfs /n/chess
Create a new game, set parameters, and play:
cd /n/chess
cd games/`{cat clone}
echo time 1800 >ctl
echo start >ctl
echo e4 >white
sleep 1
echo resign >white

BUGS AND TODOS
The board does not have the right coordinates for the right
player.
Encrypting connections should be an option.
Currently players cannot change the owners of the files.
That means anyone can take over the game.
