doko (どこ)

A simple command-line utility (and Python module) to determine your current location.

Doko is a clone of Victor Jalencas's whereami utility, but unlike whereami it supports multiple strategies for finding your location.

Kudos to Richo Healey for ideas and patches.


To install just GeoIP support, run:

$ pip install doko

However, on OS X 10.6 (Mountain Lion) or later, you can also use the much more accurate Core Location framework:

$ pip install doko[corelocation]

Using Core Location

Once you've installed the corelocation-enabled doko package, you'll need to enable Core Location in System Preferences, in the "Security" or "Security & Privacy" section. Furthermore, you must be using Wifi for it to work.


For hacking on OSX, you will likely want to install requires-corelocation.txt as well as requires.txt.

Using on the command-line

Just run the doko command:

$ doko

This will give its best guess as to your location, depending on the strategies that are available. Use the --show option to open the location in Google Maps.

More fine-grained control over strategies used and the precision returned is available. See doko --help.

Using as a module

> import doko
> doko.location('geoip')  # on any platform
Location(latitude=35.674, longitude=139.701, source='geoip')
> doko.location('corelocation')  # on OS X, using Core Location
Location(latitude=35.674851, longitude=139.701419, source='corelocation')
> doko.Location.set_precision(2)
> doko.location()
Location(latitude=35.67, longitude=139.70, source='corelocation')



  • Add a cache strategy enabled by --cache option
  • Include location source in Location tuple
  • Add --show-strategy option on the command-line


  • Make doko multiplatform, by making Core Location optional
  • Honour timeouts for GeoIP lookups
  • Provide control over precision to support privacy


  • Fetch latitude and longitude using Core Location
  • Provide backup method via GeoBytes page
