# VoteRank player reporter — shell version.
#
# Reports your server's live player count to VoteRank every 5 minutes, so your
# listing shows a real number instead of nothing. Works for any server that can
# tell you its player count from a command, a log file or a database query.
#
#   1. Get your API key: your listing -> API keys -> Create key
#   2. Set VOTERANK_KEY below (or export it in your environment)
#   3. Replace count_players() with however your server counts players
#   4. Run it:  ./voterank-players.sh
#
# Keep the key secret. Anyone who has it can report numbers as your server.

# ---------------------------------------------------------------------------
# Replace this with your own count. It must print a single number.
#
# Some examples:
#
#   MySQL:   mysql -N -u user -ppass -e "select count(*) from players where online=1" mydb
#   Log tail: grep -c "logged in" /path/to/latest.log
#   RCON:    mcrcon -H 127.0.0.1 -P 25575 -p pass "list" | grep -oE '[0-9]+' | head -1
#   HTTP:    curl -s http://127.0.0.1:8080/status | jq .online
