I’m writing a foursquare command line client in my free time – mostly so I can script my checkins, and learn the ins and outs of a staggeringly simple API. It’s also an excuse to play with AppConfig, IO::Socket::SSL and Getopt::Long. It’s an extension of an idea by Mayank Lahiri to have a perl script that can checkin to the service. I started with a very simple implementation, but I’ve expanded to slightly loftier goals. If anyone wants to grab the code and laugh at it, let me know, and I’ll post it.
