ISO3166::Countries

This gem is heavily inspired by hexorx/countries. Due to lack of maintenance of the original gem, we decided to make our own gem based on iso.org data.

Installation

Add this line to your application's Gemfile:

gem 'iso3166-countries'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install iso3166-countries

Usage

The gem is shipped with sample data that includes ISO3166 data for 3 countries(BR, CH and NZ). In order to access all countries data, you must purchase the XML data file from iso.org.

ISO3166::Countries.data_path = "path/to/data/file.xml"
country = ISO3166::Country.new("BR")
=> #<ISO3166::Country:0x00007f9253226d88 @code="BR" ...
country.alpha2
=> "BR"
country.alpha3
=> "BRA"
country.name
=> "Brazil" # English name
country.number
=> "076"
country.in_eu?
=> false
country.currency_code
=> "BRL"

ISO3166::Country.find_by(alpha2: "BR")
=> #<ISO3166::Country:0x00007f9253226d88 @code="BR" ...
ISO3166::Country.find_by(alpha3: "BRA")
=> #<ISO3166::Country:0x00007f9253226d88 @code="BR" ...
ISO3166::Country.all_names_with_codes
=> [["Brazil", "BR"], ["Switzerland", "CH"], ["New Zealand", "NZ"], ["Netherlands (the)", "NL"]]
ISO3166::Country.all
=> [#<ISO3166::Country:0x00007f9253226d88 @code="BR" ...

ISO3166::Country.find_by(alpha2: "BR") == ISO3166::Country["BR"]
=> true
