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.

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 -- 'ToJSONKeyText' can be used instead of 'ToJSONKeyValue' to encode maps -- as objects instead of arrays of pairs. This instance may be -- implemented using generics as follows: -- -- @ -- instance 'ToJSONKey' Color where -- 'toJSONKey' = 'genericToJSONKey' 'defaultJSONKeyOptions' -- @ -- -- === __Low-level implementations__ -- -- 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.
