67 shogi-server - server for CSA server protocol
70 shogi-server [OPTIONS] event_name port_number
73 server for CSA server protocol
77 a prefix of record files.
79 a port number for the server to listen.
81 --least-time-per-move n
82 Least time in second per move: 0, 1 (default 1).
83 - 0: The new rule that CSA introduced in November 2014.
84 - 1: The old rule before it.
86 maximum length of an identifier
88 when a game with the n-th move played does not end, make the game a draw.
89 Default 256. 0 disables this feature.
91 a file path in which a process ID will be written.
92 Use with --daemon option.
94 run as a daemon. Log files will be put in dir.
95 --floodgate-games game_A[,...]
96 enable Floodgate with various game names (separated by a comma)
98 enable to log network messages for players. Log files
99 will be put in the dir.
103 1. % ./shogi-server test 4081
104 Run the shogi-server. Then clients can connect to port#4081.
105 The server output logs to the stdout.
107 2. % ./shogi-server --max-moves 0 --least-time-per-move 1 test 4081
108 Run the shogi-server in compliance with CSA Protocol V1.1.2 or before.
110 3. % ./shogi-server --daemon . --pid-file ./shogi-server.pid \
111 --player-log-dir ./player-logs \
113 Run the shogi-server as a daemon. The server outputs regular logs
114 to shogi-server.log located in the current directory and network
115 messages in ./player-logs directory.
117 4. % ./shogi-server --daemon . --pid-file ./shogi-server.pid \
118 --player-log-dir ./player-logs \
119 --floodgate-games floodgate-900-0,floodgate-3600-0 \
121 Run the shogi-server with two groups of Floodgate games.
122 Configuration files allow you to schedule starting times. Consult
123 floodgate-0-240.conf.sample or shogi_server/league/floodgate.rb
126 FLOODGATE SCHEDULE CONFIGURATIONS
128 You need to set starting times of floodgate groups in
129 configuration files under the top directory. Each floodgate
130 group requires a corresponding configuration file named
131 "<game_name>.conf". The file will be re-read once just after a
134 For example, a floodgate-3600-30 game group requires
135 floodgate-3600-30.conf. However, for floodgate-900-0 and
136 floodgate-3600-0, which were default enabled in previous
137 versions, configuration files are optional if you are happy with
138 default time settings.

146 "Sunday" | "Monday" | "Tuesday" | "Wednesday" | "Thursday" |
147 "Friday" | "Saturday"
157 In addition, this configuration file allows to set parameters
158 for the specific Floodaget group. A list of parameters is the
162 Specifies a factory function name generating a pairing
163 method which will be used in a specific Floodgate game.
