  1. (<$>) :: Functor f => (a -> b) -> f a -> f b

    clash-prelude Clash.HaskellPrelude

    An infix synonym for fmap. The name of this operator is an allusion to $. Note the similarities between their types:

    ($)  ::              (a -> b) ->   a ->   b
    (<$>) :: Functor f => (a -> b) -> f a -> f b
    
    Whereas $ is function application, <$> is function application lifted over a Functor.

    Examples

    Convert from a Maybe Int to a Maybe String using show:
    >>> show <$> Nothing
    Nothing
    
    >>> show <$> Just 3
    Just "3"
    
    Convert from an Either Int Int to an Either Int String using show:
    >>> show <$> Left 17
    Left 17
    
    >>> show <$> Right 17
    Right "17"
    
    Double each element of a list:
    >>> (*2) <$> [1,2,3]
    [2,4,6]
    
    Apply even to the second element of a pair:
    >>> even <$> (2,2)
    (2,True)
    

  2. (:$$:) :: ErrorMessage -> ErrorMessage -> ErrorMessage

    clash-prelude Clash.Prelude

    Stack two pieces of error message on top of each other.

  3. (:$$:) :: ErrorMessage -> ErrorMessage -> ErrorMessage

    clash-prelude Clash.Prelude.Safe

    Stack two pieces of error message on top of each other.

  4. (-$-) :: Expr -> Expr -> Expr

    code-conjure Conjure.Engine

    $ lifted over Exprs

    > absE -$- one
    abs $ 1 :: Int
    
    Works for Int, Bool, Char argument types and their lists.

  5. (:$) :: Expr -> Expr -> Expr

    code-conjure Conjure.Engine

    function application between expressions

  6. (>$$) :: [Expr] -> Expr -> [Expr]

    code-conjure Conjure.Engine

    Lists valid applications between a list of Exprs and an Expr.

    > [plus, times] >$$ zero
    [(0 +) :: Int -> Int,(0 *) :: Int -> Int]
    

  7. (>$$<) :: [Expr] -> [Expr] -> [Expr]

    code-conjure Conjure.Engine

    Lists valid applications between lists of Exprs

    > [notE, plus] >$$< [false, true, zero]
    [not False :: Bool,not True :: Bool,(0 +) :: Int -> Int]
    

  8. (-$-) :: Expr -> Expr -> Expr

    code-conjure Conjure.Expr

    $ lifted over Exprs

    > absE -$- one
    abs $ 1 :: Int
    
    Works for Int, Bool, Char argument types and their lists.

  9. (:$) :: Expr -> Expr -> Expr

    code-conjure Conjure.Expr

    function application between expressions

  10. (>$$) :: [Expr] -> Expr -> [Expr]

    code-conjure Conjure.Expr

    Lists valid applications between a list of Exprs and an Expr.

    > [plus, times] >$$ zero
    [(0 +) :: Int -> Int,(0 *) :: Int -> Int]
