How to log a transaction

Step 1 — Parse the message

Call the parser to extract structured data:

python3 {baseDir}/parser.py "{user_message}"

This returns JSON:

{
  "amount": 500,
  "method": "bkash",
  "category": "food",
  "note": "lunch",
  "confidence": "high"
}

If amount is null → ask the user:

"কত টাকা? / How much?"

If confidence is "low" → confirm before saving:

"Did you mean: 500৳ for food via bKash? (yes/no)"

Step 2 — Save the transaction

python3 {baseDir}/logger.py log \
  --amount {amount} \
  --method {method} \
  --category {category} \
  --note "{note}"

Step 3 — Confirm to user

Reply in the same language the user wrote in:

English: "✅ Logged: {amount}৳ — {category} ({method_emoji})"

Bengali: "✅ লগ হয়েছে: {amount}৳ — {category} ({method_emoji})"

Method emojis:

• bKash → 🔴
• Nagad → 🟠
• Rocket → 🟣
• Cash → 💵
