Open a web app in your mobile browser by scanning a QR code

Use the --qr option to print a QR code for the desired URL.

Example usage

The default behaviour will print a QR code for the first available Local Area Network IP address. This is typically all you need.

$ ws --qr

To print a QR code for a URL on a different network interface, use the --list-network-interfaces option to view the available interface names.

$ ws --list-network-interfaces

Available network interfaces
- hostname: mba4.local
- lo0: 127.0.0.1
- en0: 192.168.0.200

Then supply the chosen interface name to --qr.

$ ws --qr hostname
