Currency Codes (ISO-4217)

Overview

This package mainly provides 2 data types to represent and manipulate currencies according to the ISO 4217 standard.

It also provides a handful of instances for common typeclasses (Show, Read, Random, ToJSON, FromJSON, Val, Data, Typeable, Generic, NFData).

Example

import           Data.Aeson     (ToJSON(..))
import           Data.Currency  (Currency, Alpha(..))
import           GHC.Generics   (Generic)
import qualified Safe
import qualified Data.Aeson     as Aeson
import qualified Data.Currency  as Currency


myCurrencies :: [Currency]
myCurrencies =
  [ Currency.fromAlpha EUR
  , Currency.fromAlpha USD
  ]

data Transaction = Transaction
  { amount   :: Integer
  , currency :: Currency
  } deriving (Eq, Show, Generic)

instance ToJSON Transaction where
  toJSON = 
    Aeson.genericToJSON Aeson.defaultOptions
