elsewhenbot

A bot to help convert between timezones in a telegram chat using natural language. Inspired by the Elsewhen app.

Cooked up in a day to solve a problem :)

Usage

Add @elsewhenbot to your chat
Use /add@elsewhenbot <timezone identifier> to add timezones to the output
- Find a list of timezone ids on wikipedia here
Use /remove@elsewhenbot <timezone identifier> to remove them
Use /me@elsewhenbot <timezone identifier> to tell the bot your timezone
Use /default@elsewhenbot <timezone identifier> to set the default for your chat
Message the bot @elsewhenbot Next Tuesday at 2pm and get the right times output

Deployment

Fly.io

Deploy to Fly.io with scale-to-zero (uses webhook mode):

# Create app and volume
fly apps create elsewhenbot
fly volumes create data --region lhr --size 1

# Set secrets
fly secrets set BOT_TOKEN=<your-bot-token>
fly secrets set WEBHOOK_URL=https://elsewhenbot.fly.dev/
fly secrets set WEBHOOK_SECRET=$(openssl rand -hex 32)

# Deploy
fly deploy

Importing data from an old instance

If you have existing data to import:

# First deploy to create the machine
fly deploy

# Copy your data file to the volume
fly sftp shell
> put /path/to/local/data.edn /data/data.edn

# Or use ssh
fly ssh console
cat > /data/data.edn << 'EOF'
<paste your data here>
EOF
