  1. smap :: forall (k :: Nat) a b . KnownNat k => (forall (l :: Nat) . () => SNat l -> a -> b) -> Vec k a -> Vec k b

    clash-prelude Clash.Prelude

    Apply a function to every element of a vector and the element's position (as an SNat value) in the vector.

    >>> let rotateMatrix = smap (flip rotateRightS)
    
    >>> let xss = (1:>2:>3:>Nil):>(1:>2:>3:>Nil):>(1:>2:>3:>Nil):>Nil
    
    >>> xss
    (1 :> 2 :> 3 :> Nil) :> (1 :> 2 :> 3 :> Nil) :> (1 :> 2 :> 3 :> Nil) :> Nil
    
    >>> rotateMatrix xss
    (1 :> 2 :> 3 :> Nil) :> (3 :> 1 :> 2 :> Nil) :> (2 :> 3 :> 1 :> Nil) :> Nil
    

  2. concatMap :: forall a (m :: Nat) b (n :: Nat) . (a -> Vec m b) -> Vec n a -> Vec (n * m) b

    clash-prelude Clash.Prelude.Safe

    Map a function over all the elements of a vector and concatentate the resulting vectors.

    >>> concatMap (replicate d3) (1:>2:>3:>Nil)
    1 :> 1 :> 1 :> 2 :> 2 :> 2 :> 3 :> 3 :> 3 :> Nil
    

  3. imap :: forall (n :: Nat) a b . KnownNat n => (Index n -> a -> b) -> Vec n a -> Vec n b

    clash-prelude Clash.Prelude.Safe

    Apply a function of every element of a vector and its index.

    >>> :t imap (+) (2 :> 2 :> 2 :> 2 :> Nil)
    imap (+) (2 :> 2 :> 2 :> 2 :> Nil) :: Vec 4 (Index 4)
    
    >>> imap (+) (2 :> 2 :> 2 :> 2 :> Nil)
    2 :> 3 :> *** Exception: X: Clash.Sized.Index: result 4 is out of bounds: [0..3]
    ...
    
    >>> imap (\i a -> extend (bitCoerce i) + a) (2 :> 2 :> 2 :> 2 :> Nil) :: Vec 4 (Unsigned 8)
    2 :> 3 :> 4 :> 5 :> Nil
    
    "imap f xs" corresponds to the following circuit layout:

  4. smap :: forall (k :: Nat) a b . KnownNat k => (forall (l :: Nat) . () => SNat l -> a -> b) -> Vec k a -> Vec k b

    clash-prelude Clash.Prelude.Safe

    Apply a function to every element of a vector and the element's position (as an SNat value) in the vector.

    >>> let rotateMatrix = smap (flip rotateRightS)
    
    >>> let xss = (1:>2:>3:>Nil):>(1:>2:>3:>Nil):>(1:>2:>3:>Nil):>Nil
    
    >>> xss
    (1 :> 2 :> 3 :> Nil) :> (1 :> 2 :> 3 :> Nil) :> (1 :> 2 :> 3 :> Nil) :> Nil
    
    >>> rotateMatrix xss
    (1 :> 2 :> 3 :> Nil) :> (3 :> 1 :> 2 :> Nil) :> (2 :> 3 :> 1 :> Nil) :> Nil
    

  5. type DebMap = Map BinPkgName Maybe DebianVersion

    cabal-debian Debian.Debianize.Prelude

    No documentation available.

  6. buildDebVersionMap :: IO DebMap

    cabal-debian Debian.Debianize.Prelude

    Query versions of installed packages

  7. dpkgFileMap :: IO (Map FilePath (Set BinPkgName))

    cabal-debian Debian.Debianize.Prelude

    Create a map from pathname to the names of the packages that contains that pathname using the contents of the debian package info directory varlibdpkginfo.

  8. setMapMaybe :: Ord b => (a -> Maybe b) -> Set a -> Set b

    cabal-debian Debian.Debianize.Prelude

    No documentation available.

  9. zipMaps :: Ord k => (k -> Maybe a -> Maybe b -> Maybe c) -> Map k a -> Map k b -> Map k c

    cabal-debian Debian.Debianize.Prelude

    No documentation available.

  10. concatMap :: Foldable t => (a -> [b]) -> t a -> [b]

    calligraphy Calligraphy.Prelude

    Map a function over all the elements of a container and concatenate the resulting lists.

    Examples

    Basic usage:
    >>> concatMap (take 3) [[1..], [10..], [100..], [1000..]]
    [1,2,3,10,11,12,100,101,102,1000,1001,1002]
    
    >>> concatMap (take 3) (Just [1..])
    [1,2,3]
