-- Class
-------------------------------------------------------------------------------
-- | A type that can be converted to JSON.
--
-- Instances in general /must/ specify 'toJSON' and /should/ (but don't need
-- to) specify 'toEncoding'.
--
-- An example type and instance:
--
-- @
-- \-- Allow ourselves to write 'Text' literals.
-- {-\# LANGUAGE OverloadedStrings #-}
--
-- data Coord = Coord { x :: Double, y :: Double }
--
-- instance 'ToJSON' Coord where
-- 'toJSON' (Coord x y) = 'object' [\"x\" '.=' x, \"y\" '.=' y]
--
-- 'toEncoding' (Coord x y) = 'pairs' (\"x\" '.=' x '<>' \"y\" '.=' y)
-- @
--
-- Instead of manually writing your 'ToJSON' instance, there are two options
-- to do it automatically:
--
-- * "Data.Aeson.TH" provides Template Haskell functions which will derive an
-- instance at compile time. The generated instance is optimized for your type
-- so it will probably be more efficient than the following option.
--
-- * The compiler can provide a default generic implementation for
-- 'toJSON'.
--
-- To use the second, simply add a @deriving 'Generic'@ clause to your
-- datatype and declare a 'ToJSON' instance. If you require nothing other than
-- 'defaultOptions', it is sufficient to write (and this is the only
-- alternative where the default 'toJSON' implementation is sufficient):
--
-- @
-- {-\# LANGUAGE DeriveGeneric \#-}
--
-- import "GHC.Generics"
--
-- data Coord = Coord { x :: Double, y :: Double } deriving 'Generic'
--
-- instance 'ToJSON' Coord where
-- 'toEncoding' = 'genericToEncoding' 'defaultOptions'
-- @
--
-- If on the other hand you wish to customize the generic decoding, you have
-- to implement both methods:
--
-- @
-- customOptions = 'defaultOptions'
-- { 'fieldLabelModifier' = 'map' 'Data.Char.toUpper'
-- }
--
-- instance 'ToJSON' Coord where
-- 'toJSON' = 'genericToJSON' customOptions
-- 'toEncoding' = 'genericToEncoding' customOptions
-- @
--
-- Previous versions of this library only had the 'toJSON' method. Adding
-- 'toEncoding' had to reasons:
--
-- 1. toEncoding is more efficient for the common case that the output of
-- 'toJSON' is directly serialized to a @ByteString@.
-- Further, expressing either method in terms of the other would be
-- non-optimal.
--
-- 2. The choice of defaults allows a smooth transition for existing users:
-- Existing instances that do not define 'toEncoding' still
-- compile and have the correct semantics. This is ensured by making
-- the default implementation of 'toEncoding' use 'toJSON'. This produces
-- correct results, but since it performs an intermediate conversion to a
-- 'Value', it will be less efficient than directly emitting an 'Encoding'.
-- (this also means that specifying nothing more than
-- @instance ToJSON Coord@ would be sufficient as a generically decoding
-- instance, but there probably exists no good reason to not specify
-- 'toEncoding' in new instances.)
class ToJSON a where
-- | Convert a Haskell value to a JSON-friendly intermediate type.
toJSON :: a -> Value
default toJSON :: (Generic a, GToJSON Value Zero (Rep a)) => a -> Value
toJSON = genericToJSON defaultOptions
-- | Encode a Haskell value as JSON.
--
-- The default implementation of this method creates an
-- intermediate 'Value' using 'toJSON'. This provides
-- source-level compatibility for people upgrading from older
-- versions of this library, but obviously offers no performance
-- advantage.
--
-- To benefit from direct encoding, you /must/ provide an
-- implementation for this method. The easiest way to do so is by
-- having your types implement 'Generic' using the @DeriveGeneric@
-- extension, and then have GHC generate a method body as follows.
--
-- @

-- 'toEncoding' = 'genericToEncoding' 'defaultOptions'

-------------------------------------------------------------------------------
-- Classes and types for map keys
-------------------------------------------------------------------------------
-- | Typeclass for types that can be used as the key of a map-like container
-- (like 'Map' or 'HashMap'). For example, since 'Text' has a 'ToJSONKey'
-- instance and 'Char' has a 'ToJSON' instance, we can encode a value of
-- type 'Map' 'Text' 'Char':
--
-- >>> LBC8.putStrLn $ encode $ Map.fromList [("foo" :: Text, 'a')]
-- {"foo":"a"}
--
-- Since 'Int' also has a 'ToJSONKey' instance, we can similarly write:
--
-- >>> LBC8.putStrLn $ encode $ Map.fromList [(5 :: Int, 'a')]
-- {"5":"a"}
--
-- JSON documents only accept strings as object keys. For any type
-- from @base@ that has a natural textual representation, it can be
-- expected that its 'ToJSONKey' instance will choose that representation.
--
-- For data types that lack a natural textual representation, an alternative
-- is provided. The map-like container is represented as a JSON array
-- instead of a JSON object. Each value in the array is an array with
-- exactly two values. The first is the key and the second is the value.
--
-- For example, values of type '[Text]' cannot be encoded to a
-- string, so a 'Map' with keys of type '[Text]' is encoded as follows:
--
-- >>> LBC8.putStrLn $ encode $ Map.fromList [(["foo","bar","baz" :: Text], 'a')]
-- [[["foo","bar","baz"],"a"]]
--
-- The default implementation of 'ToJSONKey' chooses this method of
-- encoding a key, using the 'ToJSON' instance of the type.
--
-- To use your own data type as the key in a map, all that is needed
-- is to write a 'ToJSONKey' (and possibly a 'FromJSONKey') instance
-- for it. If the type cannot be trivially converted to and from 'Text',
-- it is recommended that 'ToJSONKeyValue' is used. Since the default
-- implementations of the typeclass methods can build this from a
-- 'ToJSON' instance, there is nothing that needs to be written:
--
-- > data Foo = Foo { fooAge :: Int, fooName :: Text }
-- > deriving (Eq,Ord,Generic)
-- > instance ToJSON Foo
-- > instance ToJSONKey Foo
--
-- That's it. We can now write:
--
-- >>> let m = Map.fromList [(Foo 4 "bar",'a'),(Foo 6 "arg",'b')]
-- >>> LBC8.putStrLn $ encode m
-- [[{"fooName":"bar","fooAge":4},"a"],[{"fooName":"arg","fooAge":6},"b"]]
--
-- The next case to consider is if we have a type that is a
-- newtype wrapper around 'Text'. The recommended approach is to use
-- generalized newtype deriving:
--
-- > newtype RecordId = RecordId { getRecordId :: Text}
-- > deriving (Eq,Ord,ToJSONKey)
--
-- Then we may write:
--
-- >>> LBC8.putStrLn $ encode $ Map.fromList [(RecordId "abc",'a')]
-- {"abc":"a"}
--
-- Simple sum types are a final case worth considering. Suppose we have:
--
-- > data Color = Red | Green | Blue
-- > deriving (Show,Read,Eq,Ord)
--
-- It is possible to get the 'ToJSONKey' instance for free as we did
-- with 'Foo'. However, in this case, we have a natural way to go to
-- and from 'Text' that does not require any escape sequences. So, in
-- this example, 'ToJSONKeyText' will be used instead of 'ToJSONKeyValue'.
-- The 'Show' instance can be used to help write 'ToJSONKey':
--
-- > instance ToJSONKey Color where
-- > toJSONKey = ToJSONKeyText f g
-- > where f = Text.pack . show
-- > g = text . Text.pack . show
-- > -- text function is from Data.Aeson.Encoding
--
-- The situation of needing to turning function @a -> Text@ into
-- a 'ToJSONKeyFunction' is common enough that a special combinator
-- is provided for it. The above instance can be rewritten as:
--
-- > instance ToJSONKey Color where
-- > toJSONKey = toJSONKeyText (Text.pack . show)
--
-- The performance of the above instance can be improved by
-- not using 'String' as an intermediate step when converting to
-- 'Text'. One option for improving performance would be to use
-- template haskell machinery from the @text-show@ package. However,
-- even with the approach, the 'Encoding' (a wrapper around a bytestring
-- builder) is generated by encoding the 'Text' to a 'ByteString',
-- an intermediate step that could be avoided. The fastest possible
-- implementation would be:
--
-- > -- Assuming that OverloadedStrings is enabled
-- > instance ToJSONKey Color where
-- > toJSONKey = ToJSONKeyText f g
-- > where f x = case x of {Red -> "Red";Green ->"Green";Blue -> "Blue"}
-- > g x = case x of {Red -> text "Red";Green -> text "Green";Blue -> text "Blue"}
-- > -- text function is from Data.Aeson.Encoding
--
-- This works because GHC can lift the encoded values out of the case
-- statements, which means that they are only evaluated once. This
-- approach should only be used when there is a serious need to
-- maximize performance.
