concat :: Foldable t => t [a] -> [a]
base Prelude Data.List Data.Foldable
The concatenation of all the elements of a container of lists.
concat :: [[a]] -> [a]
base GHC.OldList
Concatenate a list of lists.
concatMap :: Foldable t => (a -> [b]) -> t a -> [b]
base Prelude Data.List Data.Foldable
Map a function over all the elements of a container and concatenate the resulting lists.
concatMap :: (a -> [b]) -> [a] -> [b]
base GHC.OldList
Map a function over a list and concatenate the results.
mconcat :: Monoid a => [a] -> a
base Prelude Data.Monoid
Fold a list using the monoid. For most types, the default definition for mconcat will be used, but the function is included in the class definition so that an optimized version can be provided for specific types.
biconcat :: Bifoldable t => t [a] [a] -> [a]
base Data.Bifoldable
Reduces a structure of lists to the concatenation of those lists.
biconcatMap :: Bifoldable t => (a -> [c]) -> (b -> [c]) -> t a b -> [c]
base Data.Bifoldable
Given a means of mapping the elements of a structure to lists, computes the concatenation of all such lists in order.
sconcat :: Semigroup a => NonEmpty a -> a
base Data.Semigroup
Reduce a non-empty list with <> The default definition should be sufficient, but this can be overridden for efficiency.
