I needed something very similar to http://github.com/hexorx/countries, but smaller, simpler and without any dependencies. CountryList is a tiny gem that gets all the countries, and makes country objects with some basic information inside each of them.
Inspired by countries
Add this line to your application's Gemfile:
gem 'country_list'And then execute:
$ bundle
Or install it yourself:
$ gem install country_list
Create a country object:
country = Country.new('NL')
# or like this
country = Country['NL']
Get all the countries in an Array:
countries = Country.all
Get all the country_codes in an Array:
country_codes = Country.country_codes
Get useful information about a country
country = Country.new('NL')
country.name # => 'Netherlands'
country.eu_member? # => true
country.alpha2 # => 'NL'
country.currency_code # => 'EUR'
Compare countries
netherlands = Country.new('NL')
spain = Country.new('ES')
netherlands == spain # false
netherlands == Country.new('NL') # true
After checking out the repo, run bin/setup to install dependencies. You can also 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, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
Please run rake update_cache each time you change an .yaml file.
