  1. (.=?) :: ToJSON v => Key -> Maybe v -> [Pair]

    github GitHub.Data.Content

    No documentation available.

  2. (.!=) :: Parser (Maybe a) -> a -> Parser a

    github GitHub.Internal.Prelude

    Helper for use in combination with .:? to provide default values for optional JSON object fields. This combinator is most useful if the key and value can be absent from an object without affecting its validity and we know a default value to assign in that case. If the key and value are mandatory, use .: instead. Example usage: 

    v1 <- o .:? "opt_field_with_dfl" .!= "default_val"
v2 <- o .:  "mandatory_field"
v3 <- o .:? "opt_field2"

  3. (.:) :: FromJSON a => Object -> Key -> Parser a

    github GitHub.Internal.Prelude

    Retrieve the value associated with the given key of an Object. The result is empty if the key is not present or the value cannot be converted to the desired type. This accessor is appropriate if the key and value must be present in an object for it to be valid. If the key and value are optional, use .:? instead.

  4. (.:?) :: FromJSON a => Object -> Key -> Parser (Maybe a)

    github GitHub.Internal.Prelude

    Retrieve the value associated with the given key of an Object. The result is Nothing if the key is not present or if its value is Null, or empty if the value cannot be converted to the desired type. This accessor is most useful if the key and value can be absent from an object without affecting its validity. If the key and value are mandatory, use .: instead.

  5. (.=) :: (KeyValue e kv, ToJSON v) => Key -> v -> kv

    github GitHub.Internal.Prelude

    No documentation available.

  6. (.:) :: FromJSON a => Value -> Text -> a

    github-rest GitHub.REST

    Get the given key from the Value, erroring if it doesn't exist.

  7. (.=) :: (KeyValue e kv, ToJSON v) => Key -> v -> kv

    graphql-client Data.GraphQL.Bootstrap

    No documentation available.

  8. (.:) :: FromGraphSON a => KeyMap GValue -> Key -> Parser a

    greskell Data.Greskell

    Like Aeson's .:, but for FromGraphSON.

  9. (.#) :: (Function f a r, SimpleMergeable r, UnionView u) => f -> u a -> r

    grisette Grisette.Core

    Helper for applying functions on UnionView and SimpleMergeable. 

    >>> let f :: Integer -> Union Integer = \x -> mrgIf (ssym "a") (mrgSingle $ x + 1) (mrgSingle $ x + 2)

>>> f .# (mrgIf (ssym "b" :: SymBool) (mrgSingle 0) (mrgSingle 2) :: Union Integer)
{If (&& b a) 1 (If b 2 (If a 3 4))}

  10. (.&&) :: LogicalOp b => b -> b -> b

    grisette Grisette.Core

    Symbolic conjunction
