Kamil 'Kamaś' Bruchal 74cb302f64 chore: track go.mod, go.sum, and missing test files 
These were never committed (hidden by status.showUntrackedFiles=no): without
go.mod/go.sum a fresh clone would not build, and the source files committed in
abb38e3 were missing their accompanying tests.

README.md

Dyżur-bot

A telegram bot for managing the cleaning rota in hackerspace. Bot offers weekly reminders about cleaning duties as well as on demand informations. Backend read the schedule from a Google sheet, store it in local JSON file.

Running

Requires GOOGLE_API_KEY, GOOGLE_SHEETS_ID, and BOT_TOKEN in the environment or a .env file (see service.go/sheet.go for optional SHEET_RANGE, ROTA_CACHE_PATH, SYNC_INTERVAL). Then:

go run ./cmd/dyzur-bot

The service loads the cached rota, syncs from Google Sheets in the background on SYNC_INTERVAL (default 30m), and runs the Telegram bot via long polling until interrupted (Ctrl-C / SIGTERM).

Run exactly one instance per bot token. The bot uses long polling (getUpdates); two concurrent pollers on the same token make Telegram return HTTP 409 Conflict and updates get dropped. Do not scale this to multiple replicas.

Docker

docker build -t dyzur-bot .
docker run --rm --env-file .env -v dyzur-data:/data dyzur-bot

The image is a static binary on distroless (timezone data is embedded, so reminders work without system tzdata). The rota cache lives at /data/rota.json (ROTA_CACHE_PATH); mount a volume at /data to persist it across restarts.

Commands

  • /kto_sprzata — who is on cleaning duty this week.
  • /sync — refresh the rota from Google Sheets now.

Reminders

If GROUP_CHAT_ID is set, the bot posts a weekly duty reminder to that chat. Schedule (all optional, with defaults): REMINDER_WEEKDAY (default Monday), REMINDER_HOUR (default 9, 0–23), DUTY_AHEAD_DAYS (default 14). The hour is interpreted in Europe/Warsaw time. The reminder announces who is on duty DUTY_AHEAD_DAYS from the fire time — e.g. every Monday 09:00, who cleans two weeks out. Leave GROUP_CHAT_ID unset to disable reminders.
