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

    hledger-web Hledger.Web.Import

    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.

  2. (<:>) :: forall a (n :: Nat) . a -> NList n a -> NList (n + 1) a

    indexed-containers Data.NList

    Prepend an element to a list. 

    'a' <:> singleton 'b' === mk2 'a' 'b'

  3. (<:) :: JType -> JType -> TMonad ()

  4. (<<:>) :: TMonad JType -> TMonad JType -> TMonad ()

    jmacro Language.Javascript.JMacro.TypeCheck

  5. (=:) :: ToJExpr a => JExpr -> a -> JStat

    jmacro Language.Javascript.JMacro.Util

  6. ($:) :: forall (m :: Type -> Type) a . (Monad m, ToHtml a) => (HtmlT m () -> HtmlT m ()) -> a -> HtmlT m ()

  7. (~:) :: forall (t :: ElfNodeType) (a :: ElfClass) . ElfXX t a -> ElfListXX a -> ElfListXX a

    melf Data.Elf

    Helper for ElfListCons

  8. (=:) :: k -> a -> Map k a

    miso Miso.Util

    Smart constructor for Attributes. This function is helpful when constructing numerous Attributes Example shown below. 

    div_ [ style_  $ ("background" =: "red" <> "width" =: "250px" <> "height" =: "250px") ] []

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

    morpheus-graphql-client Data.Morpheus.Client.CodeGen.Internal

    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.

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

    morpheus-graphql-client Data.Morpheus.Client.CodeGen.Internal

    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.
