A really simple currency converter using Xurrency and XavierMedia APIs. Compatible with Ruby 1.8, 1.9 and JRuby.
Just require it and all your numeric stuff gets this fancy DSL for free:
30.eur.to_usd # => 38.08 150.eur.to_usd # => 190.4 239.usd.to_eur # => 187.98 # These don't even hit the Internets! # (They take advantage of Rails cache) 70.usd.to_chf # => 71.9
But what if you want to do the currency exchange according to a specific date in the past? Just do this:
# You can use any time or date object 42.eur.at(1.year.ago).to_usd # => 60.12 42.eur.at(Time.parse('2009-09-01')).to_usd # => 60.12
In your Gemfile:
Not using Rails?
Then you have to manually install the gem:
gem install simple_currency
And manually require it as well:
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add specs for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. If you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull.
Send me a pull request. Bonus points for topic branches.
