Chicago Ruby Hack Night - JSON

  • Jun 12, 2013 · 6:30 PM

Come on out and hack!

A lot of data is transferred in JSON format which is easy for programs to read but hard for humans since it's all one line.  Let's solve this problem with a Ruby program that formats JSON so that we can read it easily.  This problem has been solved before, of course, but not by you so it's a good exercise.

Sample JSON data is shown below.  Check JSON Lint for an example of an app that solves this problem.  If you get the formatting done early you can also try validating the JSON, too.

We'll pair up to work on this Ruby problem. All Rubyists are welcome, including beginners. Bring your laptop with ruby installed.

Enova Financial, our hosts, will provide food and drink.
