CTA Redux : CTA Redux

Good data is useless if it's hard to access.
CTA Redux takes obscure data from the Chicago Transit Authority and makes it easy to use.

require 'cta_redux'
CTA::TrainTracker.key = 'foo'

# Access GTFS data with the power of Sequel
api_response = CTA::Stop.first(:stop_name => "Armitage").predictions!

api_response.predictions.each do |p|
  puts "A #{p.direction} #{p.route.long_name} train will be arriving at Armitage in #{p.minutes} minutes."
end

$ ruby ~/test.rb
A Loop-bound Brown Line train will be arriving at Armitage in 3 minutes.
A Loop-bound Brown Line train will be arriving at Armitage in 12 minutes.
