Irish Rail API Ruby Wrapper

I wrote most of this on the train, as is appropriate.

It's a trivial wrapper for the Irish Rail real time (whut?) train times system, in Ruby. It uses the HTTP GET API that was thankfully supplied along with the more interesting SOAP API, so a tiddly simple set up with RestClient and Nokogiri (two of my favourite things ever) to pull and process the XML data into Hashes for great value.

Usage

Grab the IERail gem

$ gem install ierail

require 'ierail'

ir = IERail.new

Find all Southbound trains serving Clongriffin station

trains = ir.southbound_from('clongriffin')

Find all trains serving Clongriffin in the next 30 minutes

trains = ir.station_times('clongriffin', 30)

trains.each { |t| p t.inspect }

Find all Northbound trains serving Clongriffin before / after a certain time

trains = ir.northbound_from('clongriffin').after('HH:MM')
trains = ir.northbound_from('clongriffin').before('HH:MM')

NB: "HH:MM" must be soon, as the API, by default, returns upcoming arrivals

Find all Southbound trains from Malahide in the next N minutes

trains = ir.southbound_from('malahide').in(N)

Find out information for a specific train

trains = ir.station('clongriffin', 60)

trains.first.last_location # "Arrived Harmonstown"

trains.first.origin # {:name=>"Greystones", :time=>2013-05-13 22:10:00 +0100}

trains.first.destination # {:name=>"Malahide", :time=>2013-05-13 22:10:00 +0100}

trains.first.arrival # {:scheduled=>2013-05-13 22:09:00 +0100, :expected=>2013-05-13 22:10:00 +0100}

trains.first.departure # {:scheduled=>2013-05-13 22:09:00 +0100, :expected=>2013-05-13 22:10:00 +0100}

trains.first.duein # "2"

trains.first.late? # 0 || 1
