# ProductSpy

ProductSpy is made for parsing product URLs, i.e. Amazon-URLs, to get
the product keys and creating product URLs based on these keys. This can
be used to identify products based on the url or just to clean up
product URLs.

## Installation

Add this line to your application's Gemfile:

    gem 'product_spy'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install product_spy

## Usage

```ruby
# Parsing URLs
ProductSpy.parse('https://www.amazon.de/dp/B004O9DF6O') => ['www.amazon.de', ['B004O9DF6O']]

# Building URLs
ProductSpy.build('amazon.de', ['B004O9DF6O']) # => https://www.amazon.de/dp/B004O9DF6O

# defining patterns
ProductSpy.setup do |config|
  config.host 'www.amazon.de', :aliases => ['amazon.de'] do |host|
