  1. map :: (a -> b) -> [a] -> [b]

    faktory Faktory.Prelude

    map f xs is the list obtained by applying f to each element of xs, i.e.,

    map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
    map f [x1, x2, ...] == [f x1, f x2, ...]
    
    this means that map id == id

    Examples

    >>> map (+1) [1, 2, 3]
    [2,3,4]
    
    >>> map id [1, 2, 3]
    [1,2,3]
    
    >>> map (\n -> 3 * n + 1) [1, 2, 3]
    [4,7,10]
    

  2. map :: Natural n => (a -> b) -> T n a -> T n b

    fixed-length Data.FixedLength

    No documentation available.

  3. map :: (HVectorF v, ArityC c (ElemsF v)) => Proxy c -> (forall a . c a => f a -> g a) -> v f -> v g

    fixed-vector-hetero Data.Vector.HFixed

    Apply function to every value of parametrized product.

    >>> map (Proxy @Num) (Identity . fromMaybe 0) (mk2F (Just 12) Nothing :: HVecF '[Double, Int] Maybe)
    [Identity 12.0,Identity 0]
    

  4. map :: (a -> b) -> Map k a -> Map k b

    hashmap Data.HashMap

    Map a function over all values in the map.

  5. map :: (Hashable b, Ord b) => (a -> b) -> Set a -> Set b

    hashmap Data.HashSet

    map f s is the set obtained by applying f to each element of s. It's worth noting that the size of the result may be smaller if, for some (x,y), x /= y && f x == f y

  6. map :: (Unbox a, Unbox b) => (a -> b) -> Histogram bin a -> Histogram bin b

    histogram-fill Data.Histogram

    No documentation available.

  7. map :: forall (v :: Type -> Type) a b bin . (Vector v a, Vector v b) => (a -> b) -> Histogram v bin a -> Histogram v bin b

    histogram-fill Data.Histogram.Generic

    fmap lookalike. It's not possible to create Functor instance because of type class context.

  8. map :: (a -> b) -> [a] -> [b]

    hledger-web Hledger.Web.Import

    map f xs is the list obtained by applying f to each element of xs, i.e.,

    map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
    map f [x1, x2, ...] == [f x1, f x2, ...]
    
    this means that map id == id

    Examples

    >>> map (+1) [1, 2, 3]
    [2,3,4]
    
    >>> map id [1, 2, 3]
    [1,2,3]
    
    >>> map (\n -> 3 * n + 1) [1, 2, 3]
    [4,7,10]
    

  9. map :: (a <-> b) -> [a] <-> [b]

    invertible Data.Invertible.List

    Apply a bijection over a list using map.

  10. map :: (a <-> b) -> [a] <-> [b]

    invertible Data.Invertible.Prelude

    Apply a bijection over a list using map.
