roadtrip

DESCRIPTION:

This is a quick little gem that uses Google Maps to determine the distance, duration and fuel costs for driving between two user defined points. Just like Google Maps, the starting and destination points can be full addresses, city/state combinations, or just ZIP codes.

EXAMPLE USE:

Assume a user is traveling from ZIP code 30032 to ZIP code 90210, that gas costs $2.75 per gallon and that the car being driven has a fuel economy of 30mpg. The following would be used to create an instance of a Roadtrip::Trip, labeled “t” in this case:

t = Roadtrip::Trip.new(30032, 90210, 2.75, 30)

So in general, the user supplies the following parameters:

* Starting Location * Destination * Cost Per Gallon - the cost for a gallon of gas, on average * Miles Per Gallon - the MPG for your vehicle

FEATURES:

Each “RoadTrip::Trip” object has the following methods available:

t.distance t.duration t.cost t.round_trip_cost

TESTS:

This is a brand new gem (and my first), so I'm still working through adding Cucumber/RSpec tests. For now, this was just a proof of concept so I knew how to create/deploy a gem. I plan on going back and continuing development of this gem using BDD/TDD. More to follow…

REQUIREMENTS:

This gem has the following dependencies:

INSTALL:

(sudo) gem install roadtrip

Then in your ruby code, add: require 'rubygems' require 'roadtrip'

Note: This gem is hosted at www.rubygems.org. Be sure you have rubygems.org (or gemcutter.org) listed as a gem source on your system…or see the documentation on their site for how to add this as a source.
