357−-- >>> LBC8.putStrLn $ encode $ Map.fromList [("foo" :: Text, 'a')]

365−-- JSON documents only accept strings as object keys. For any type

367−-- expected that its 'ToJSONKey' instance will choose that representation.
369−-- For data types that lack a natural textual representation, an alternative
370−-- is provided. The map-like container is represented as a JSON array
371−-- instead of a JSON object. Each value in the array is an array with
372−-- exactly two values. The first is the key and the second is the value.
374−-- For example, values of type '[Text]' cannot be encoded to a
375−-- string, so a 'Map' with keys of type '[Text]' is encoded as follows:
377−-- >>> LBC8.putStrLn $ encode $ Map.fromList [(["foo","bar","baz" :: Text], 'a')]
378−-- [[["foo","bar","baz"],"a"]]
380−-- The default implementation of 'ToJSONKey' chooses this method of
381−-- encoding a key, using the 'ToJSON' instance of the type.
383−-- To use your own data type as the key in a map, all that is needed
384−-- is to write a 'ToJSONKey' (and possibly a 'FromJSONKey') instance
385−-- for it. If the type cannot be trivially converted to and from 'Text',
386−-- it is recommended that 'ToJSONKeyValue' is used. Since the default
387−-- implementations of the typeclass methods can build this from a
388−-- 'ToJSON' instance, there is nothing that needs to be written:
390−-- > data Foo = Foo { fooAge :: Int, fooName :: Text }
391−-- > deriving (Eq,Ord,Generic)
392−-- > instance ToJSON Foo
393−-- > instance ToJSONKey Foo
395−-- That's it. We can now write:
397−-- >>> let m = Map.fromList [(Foo 4 "bar",'a'),(Foo 6 "arg",'b')]
398−-- >>> LBC8.putStrLn $ encode m
399−-- [[{"fooName":"bar","fooAge":4},"a"],[{"fooName":"arg","fooAge":6},"b"]]
401−-- The next case to consider is if we have a type that is a
402−-- newtype wrapper around 'Text'. The recommended approach is to use
403−-- generalized newtype deriving:
405−-- > newtype RecordId = RecordId { getRecordId :: Text }
406−-- > deriving (Eq,Ord,ToJSONKey)
408−-- Then we may write:
410−-- >>> LBC8.putStrLn $ encode $ Map.fromList [(RecordId "abc",'a')]
413−-- Simple sum types are a final case worth considering. Suppose we have:
415−-- > data Color = Red | Green | Blue
416−-- > deriving (Show,Read,Eq,Ord)
418−-- It is possible to get the 'ToJSONKey' instance for free as we did
419−-- with 'Foo'. However, in this case, we have a natural way to go to
420−-- and from 'Text' that does not require any escape sequences. So
421−-- 'ToJSONKeyText' can be used instead of 'ToJSONKeyValue' to encode maps
422−-- as objects instead of arrays of pairs. This instance may be
423−-- implemented using generics as follows:
426−-- instance 'ToJSONKey' Color where
427−-- 'toJSONKey' = 'genericToJSONKey' 'defaultJSONKeyOptions'
430−-- === __Low-level implementations__
432−-- The 'Show' instance can be used to help write 'ToJSONKey':
434−-- > instance ToJSONKey Color where
435−-- > toJSONKey = ToJSONKeyText f g
436−-- > where f = Text.pack . show
437−-- > g = text . Text.pack . show
438−-- > -- text function is from Data.Aeson.Encoding
440−-- The situation of needing to turning function @a -> Text@ into
441−-- a 'ToJSONKeyFunction' is common enough that a special combinator
442−-- is provided for it. The above instance can be rewritten as:
444−-- > instance ToJSONKey Color where
445−-- > toJSONKey = toJSONKeyText (Text.pack . show)
447−-- The performance of the above instance can be improved by
448−-- not using 'String' as an intermediate step when converting to
449−-- 'Text'. One option for improving performance would be to use
450−-- template haskell machinery from the @text-show@ package. However,
451−-- even with the approach, the 'Encoding' (a wrapper around a bytestring
452−-- builder) is generated by encoding the 'Text' to a 'ByteString',
453−-- an intermediate step that could be avoided. The fastest possible
454−-- implementation would be:
456−-- > -- Assuming that OverloadedStrings is enabled
457−-- > instance ToJSONKey Color where
458−-- > toJSONKey = ToJSONKeyText f g
459−-- > where f x = case x of {Red -> "Red";Green ->"Green";Blue -> "Blue"}
460−-- > g x = case x of {Red -> text "Red";Green -> text "Green";Blue -> text "Blue"}
461−-- > -- text function is from Data.Aeson.Encoding
463−-- This works because GHC can lift the encoded values out of the case
464−-- statements, which means that they are only evaluated once. This
465−-- approach should only be used when there is a serious need to
466−-- maximize performance.
