Qrcode

QR Code

Generate the QR code to a file, then send it with send_message (attachment). Check for a tool first: command -v qrencode, else try Python.

With qrencode (preferred)

qrencode -o tmp/qr.png -s 8 "https://example.com"      # PNG
qrencode -t ANSIUTF8 "https://example.com"             # preview in terminal

Python fallback

# Try whichever is installed: segno (no deps) or qrcode (needs Pillow)
python3 - <<'PY'
try:
    import segno
    segno.make("https://example.com").save("tmp/qr.png", scale=8)
except ImportError:
    import qrcode
    qrcode.make("https://example.com").save("tmp/qr.png")
print("wrote tmp/qr.png")
PY

Useful payload formats

• URL: https://example.com
• Wi-Fi: WIFI:T:WPA;S:<ssid>;P:<password>;;
• Email: mailto:someone@example.com
• Phone: tel:+15551234567
• Plain text: any string.

Guidance

• Write images under the chat working directory's tmp/, then send via send_message with attachment_path.
• Keep the payload short — dense QR codes scan poorly; for long URLs consider shortening first.
• If neither qrencode nor a Python QR lib is available, say so and offer the terminal-art form or installation hint.
