Simple Echo Bot¶

A minimal echo bot with zero external dependencies. It receives text messages and echoes them back.

See examples/simple_echo.py in the repository.

Usage¶

python examples/simple_echo.py

How It Works¶

1. Creates a WeiLink instance and logs in via QR code.
2. Enters a polling loop with wl.recv(timeout=35.0).
3. For each incoming text message, replies with "Echo: <text>" using wl.send().

Key Features Demonstrated¶

• Login flow -- WeiLink() + wl.login() to authenticate.
• Long-polling -- wl.recv(timeout=...) blocks until messages arrive or the timeout elapses.
• Sending text -- wl.send(user, text) sends a plain text reply.
• Graceful shutdown -- catches KeyboardInterrupt and calls wl.close().
