So what is it?

whereami is a simple command-line utility that outputs your geographical coordinates, as determined by Core Location, which uses nearby WiFi networks with known positions to pinpoint your location. It prints them to the standard output in an easy to parse format, in good UNIX fashion.


This version of whereami only works in versions of Mac OS X 10.9 (Mavericks) or greater; as it is implemented in Swift. Why in Swift? Well, mostly because the command-line parsing libraries I could find in Objective-C where either a nuisance to install (because of lack of CocoaPods support) or required a lot of code to configure the options I need. On the other hand, SwiftCLI makes it really easy.

To build it, you will require Xcode 6.1 and optionally xctool. You can build it from the command line using either xcodebuild or xctool, whichever you like best. Both should work equally well, but xctool’s output is fancier. You can install xctool using homebrew.


whereami comes with batteries included. You just need to clone the project to your local machine, switch to the swift branch, init the submodules, and install it using xcodebuild/xctool. In the near future, I will make that branch the main one, but not just yet.

$ git clone whereami
$ cd whereami
$ git checkout swift
$ git submodule update --init --recursive
$ xctool install


Once whereami is installed, you can just invoke it to output your location:

$ whereami

This is the default format, the tersest. You can also make it output JSON:

$ whereami --format json
{"latitude":41.386905825791, "longitude": 2.14425782089087}

Or even output in sexagesimal form:

$ whereami --format sexagesimal
41° 23′ 12.8609728477426″, 2° 8′ 39.3281552071449″

Apart from these options, the standard --version and --help options are recognized.
