bumblebee-status/bumblebee_status/modules/contrib/publicip.py

"""
Displays information about the public IP address associated with the default route:
    * Public IP address
    * Country Name
    * Country Code
    * City Name
    * Geographic Coordinates

Left mouse click on the widget forces immediate update.
Any change to the default route will cause the widget to update.

Requirements:
    * netifaces

Parameters:
    * publicip.format: Format string (defaults to ‘{ip} ({country_code})’)
    * Available format strings - ip, country_name, country_code, city_name, coordinates

Examples:
    * bumblebee-status -m publicip -p publicip.format="{ip} ({country_code})"
    * bumblebee-status -m publicip -p publicip.format="{ip} which is in {city_name}"
    * bumblebee-status -m publicip -p publicip.format="Your packets are right here: {coordinates}"
