Spot::Rate

Get current currency spot rates

Installation

Add this line to your application's Gemfile:

gem 'spot-rate'

And then execute:

$ bundle

Or install it yourself as:

$ gem install spot-rate

Usage

A SpotRate instance will by default use the GoogleCurrencyConverter if no other currency converters are registered:

require 'spot-rate'

puts Time.now
# => 2013-05-01 18:34:09 -0700
puts SpotRate.new(:from_currency => 'USD', :to_currency => 'CAD').spot_rate
# => 1.01689986

# or, more concisely:
puts SpotRate['USD' => 'CAD']
# => 1.01689986

If you'd like to register your own currency converter, use the .register_currency_converter method:

require 'spot-rate'

class MyRandomCurrencyConverter
  def initialize from_currency, to_currency
    @from_currency = from_currency
    @to_currency   = to_currency
  end

  def spot_rate
    rand # yolo
  end
end

SpotRate.register_currency_converter(:random_converter, MyRandomCurrencyConverter)
spot_rate = SpotRate.new(:from_currency => 'USD', :to_currency => 'CAD')
puts spot_rate.use(:random_converter).spot_rate
# => 0.5363022464905228
puts spot_rate.spot_rate # will go back to using the pre-packaged default Google converter
# => 1.01689986
