json-alt: Union 'alternative' or Either that has untagged JSON encoding.
This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.
Parsing JSON with Aeson often requires decoding fields that have more than one Haskell type.
So we have:
data a :|: b = AltLeft a
| AltRight b
printIt = print . (fromJSON :: ByteString -> Int :|: Bool)
main = do
printIt "1" -- AltLeft 1
printIt "true" -- AltRight True
printIt "null" -- errors!To generate types for larger JSON documents,
you might use json-autotype.
This is separate package so that users
do not have to keep json-autotype as runtime
dependency.
