Gem currency_to_words

Provides a view helper for Rails that translate a currency amount to words (eg. to_words(200) => ‘dvě stě’).

This helper comes with two supported locales (Czech and Polish) but it is possible and easy to implement your own (see “Implementing a new locale”).

Installation

Add the gem to your Gemfile.

gem 'currency_to_words'

Usage

Install gem and create locale file in your project where you want to provide translation from currency to words. You can use locale file from I18n files below section or create your own.

Examples

In your views write for example:

currency_to_words(235.58)

Missing locale?

If you need locale that is not supported yet, you can easily add one. All you need to do is translated locale file and create class in /lib. Convention is that the class has to be named [locale]Currency.

So for example EnCurrency or FrCurrency. So override or duplicate the existing class and add diffrences of your language. Thats it!

Inspiration

This project is heavily inspirated by bcarrere/currency-in-words and uses blocks of code from this repository.

Reason for creating my own repository was requirement to use I18n gem for “currency to words” translation and also for settings. This means, that this gem can be configured from locale file and translation is not hardcoded to source of library.
