FlagIcon

Purpose

An attempt to map languages to country flags!

Approach

Matching flags to languages can be really tricky and even problematic sometimes because there is no direct association between languages and countries since the same language is spoken in many countries and many languages are spoken in a single country.

So for a title from Mexico which has spanish as the official language the spanish flag will appear.

If you notice any flags being mismatched please raise an issue or even better open a pull request

Installation

Add this line to your application's Gemfile:

gem 'flag_icon'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install flag_icon
