Kamil 'Kamaś' Bruchal 825331dce5 fix: match bot commands addressed with @botusername in groups 
In group chats Telegram appends the bot addressee to the bot_command
entity (/sync@hs_dyzur_bot), and the library's MatchTypeCommand compares
the whole token verbatim, so commands never matched. Replace it with
custom MatchFuncs that read the bot_command entity span and strip any
@suffix before comparing the command name.

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).

When SHEET_RANGE is unset, the bot reads the current year's tab (e.g. 2026!A1:G100), resolved on every sync — so it follows the New Year rollover automatically without a restart. A sync that fails, or that returns no duty weeks (e.g. a next-year tab that exists but hasn't been filled in yet), keeps the last-good cache instead of clearing it; if no sync succeeds for 6h the bot logs a loud stale-cache error.

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 (throttled to once per minute across the chat to avoid spamming the Sheets API).

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.
