README
Moola
A Crystal library for dealing with money (inspired by RubyMoney)
Installation
tested with Crystal 0.28.0
Add this to your application's shard.yml:
dependencies:
moola:
github: dorkrawk/moola
Usage
Basic Money object
money = Moola.new(42_00) # creates a new Moola::Money object
money.format # "$42.00"
money.cents # 4200
money.zero? # false
money.to_f # 42.0
-money == Moola.new(-42_00) # true
Comparisons
Moola::Money.new(5_00) == Moola::Money.new(5_00) # true
Moola::Money.new(5_00) == Moola::Money.new(7_00) # false
Moola::Money.new(5_00, "USD") == Moola::Money.new(5_00, "EUR") # false
[Moola::Money.new(5_00), Moola::Money.new(2_00), Moola::Money.new(7_00)].sort # sorted by amount
Arithmetic
Moola::Money.new(5_00) + Moola::Money.new(10_00) == Moola::Money.new(15_00)
Moola::Money.new(15_00) + Moola::Money.new(12_00) == Moola::Money.new(3_00)
Moola::Money.new(15_00) / 3 == Moola::Money.new(5_00)
Moola::Money.new(5_00) * 3 == Moola::Money.new(15_00)
Conversion
Moola::Exchange.add_conversion(Moola::Currency.find("usd"), Moola::Currency.find("cad"), 1.3)
money = Moola.new(1_00, "USD")
money.convert_to(Moola::Currency.find("cad")) == Moola.new(1_30, "cad")
