Description

Types and functions for handling our representation of a key:value pair in a JSON object.

Synopsis

- _jsonAssocKey :: JString
- _jsonAssocKeyTrailingWS :: ws
- _jsonAssocValPreceedingWS :: ws
- _jsonAssocVal :: a
}
class HasJAssoc c ws a | c -> ws a where
- jAssoc :: Lens' c (JAssoc ws a)
- jsonAssocKey :: Lens' c JString
- jsonAssocKeyTrailingWS :: Lens' c ws
- jsonAssocVal :: Lens' c a
- jsonAssocValPreceedingWS :: Lens' c ws
parseJAssoc :: (Monad f, CharParsing f) => f ws -> f a -> f (JAssoc ws a)
jAssocAlterF :: (Monoid ws, Functor f) => Text -> (Maybe a -> f (Maybe a)) -> Maybe (JAssoc ws a) -> f (Maybe (JAssoc ws a))

Key/value pair type

data JAssoc ws a Source #

This type represents the key:value pair inside of a JSON object.

It is built like this so that we can preserve any whitespace information that may surround it.

Constructors

JAssoc
Fields _jsonAssocKey :: JString _jsonAssocKeyTrailingWS :: ws _jsonAssocValPreceedingWS :: ws _jsonAssocVal :: a

Parse

parseJAssoc :: (Monad f, CharParsing f) => f ws -> f a -> f (JAssoc ws a) Source #

Parse a single "key:value" pair

Update

jAssocAlterF :: (Monoid ws, Functor f) => Text -> (Maybe a -> f (Maybe a)) -> Maybe (JAssoc ws a) -> f (Maybe (JAssoc ws a)) Source #

Helper function for trying to update/create a JAssoc value in some Functor. This function is analogus to the alterF function.
