65 shogi-server - server for CSA server protocol
68 shogi-server [OPTIONS] event_name port_number
71 server for CSA server protocol
75 a prefix of record files.
77 a port number for the server to listen.
79 --least-time-per-move n
80 Least time in second per move: 0, 1 (default 1).
81 - 0: The new rule that CSA introduced in November 2014.
82 - 1: The old rule before it.
84 when a game with the n-th move played does not end, make the game a draw.
85 Default 256. 0 disables this feature.
87 a file path in which a process ID will be written.
88 Use with --daemon option.
90 run as a daemon. Log files will be put in dir.
91 --floodgate-games game_A[,...]
92 enable Floodgate with various game names (separated by a comma)
94 enable to log network messages for players. Log files
95 will be put in the dir.
99 1. % ./shogi-server test 4081
100 Run the shogi-server. Then clients can connect to port#4081.
101 The server output logs to the stdout.
103 2. % ./shogi-server --daemon . --pid-file ./shogi-server.pid \
104 --player-log-dir ./player-logs \
106 Run the shogi-server as a daemon. The server outputs regular logs
107 to shogi-server.log located in the current directory and network
108 messages in ./player-logs directory.
110 3. % ./shogi-server --daemon . --pid-file ./shogi-server.pid \
111 --player-log-dir ./player-logs \
112 --floodgate-games floodgate-900-0,floodgate-3600-0 \
114 Run the shogi-server with two groups of Floodgate games.
115 Configuration files allow you to schedule starting times. Consult
116 floodgate-0-240.conf.sample or shogi_server/league/floodgate.rb
119 FLOODGATE SCHEDULE CONFIGURATIONS
121 You need to set starting times of floodgate groups in
122 configuration files under the top directory. Each floodgate
123 group requires a corresponding configuration file named
124 "<game_name>.conf". The file will be re-read once just after a
127 For example, a floodgate-3600-30 game group requires
128 floodgate-3600-30.conf. However, for floodgate-900-0 and
129 floodgate-3600-0, which were default enabled in previous
130 versions, configuration files are optional if you are happy with
131 default time settings.
134 # This is a comment line
138 DoW := "Sun" | "Mon" | "Tue" | "Wed" | "Thu" | "Fri" | "Sat" |
139 "Sunday" | "Monday" | "Tuesday" | "Wednesday" | "Thursday" |
140 "Friday" | "Saturday"
150 In addition, this configuration file allows to set parameters
151 for the specific Floodaget group. A list of parameters is the
155 Specifies a factory function name generating a pairing
156 method which will be used in a specific Floodgate game.
157 ex. set pairing_factory floodgate_zyunisen
159 Specifies a sacrificed player.
