Territorial

If you have to work with lists of ISO 3166-1 alpha-2 country codes that sometimes include fake codes that should be expanded to a longer list, e.g. 'EU', or if you have to deal with lists of territory metadata like 'EU -FR' then territorial will help. It defines some commonly seen default expansion codes, and allows you to correctly expand a string like 'EU -FR' into an array of 2-letter country codes

Installation

Add this line to your application's Gemfile:

gem 'territorial'

And then execute:

$ bundle

Or install it yourself as:

$ gem install territorial

Usage

Basic region expansion is very simple:

Territorial.expand(:GSA)
# => ['DE', 'CH', 'AT']

Territorial.expand(['GSA', EFTA'])
# => ['DE', 'CH', 'AT', 'NO', 'LI', 'IS']

Available regions:

• GSA - Germany, Switzerland, Austria
• EU - European Union
• EFTA - European Free Trade Association
• WW - Worldwide

You can instantiate a Territorial instance directly with your own extra regions defined, or override the defaults:

t = Territorial.new(Anglophone: ['GB', 'US', 'CA', 'AU', 'NZ', 'ZA'])
t.expand(:Anglophone)
# => ['GB', 'US', 'CA', 'AU', 'NZ', 'ZA']

You can also parse strings listing territories and regions:

t = Territorial.new
t.parse('GSA -DE')
# => ['AT', 'CH']

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
