unions :: [IntMap a] -> IntMap a
containers Data.IntMap.Strict, containers Data.IntMap.Lazy
The union of a list of maps. > unions [(fromList [(5, "a"), (3, "b")]), (fromList [(5, "A"), (7, "C")]), (fromList [(5, "A3"), (3, "B3")])] > == fromList [(3, "b"), (5, "a"), (7, "C")] > unions [(fromList [(5, "A3"), (3, "B3")]), (fromList [(5, "A"), (7, "C")]), (fromList [(5, "a"), (3, "b")])] > == fromList [(3, "B3"), (5, "A3"), (7, "C")]
unionsWith :: (a -> a -> a) -> [IntMap a] -> IntMap a
containers Data.IntMap.Strict, containers Data.IntMap.Lazy
The union of a list of maps, with a combining operation. > unionsWith (++) [(fromList [(5, "a"), (3, "b")]), (fromList [(5, "A"), (7, "C")]), (fromList [(5, "A3"), (3, "B3")])] > == fromList [(3, "bB3"), (5, "aAA3"), (7, "C")]
unions :: Ord a => [Set a] -> Set a
containers Data.Set
The union of a list of sets: (unions == foldl union empty).
Node :: a -> Forest a -> Tree a
containers Data.Tree
Q :: (forall m. Quasi m => m a) -> Q a
template-haskell Language.Haskell.TH.Syntax
discardingRasterizer :: IO a -> IO a
OpenGL Graphics.Rendering.OpenGL.GL.PerFragment
preservingMatrix :: IO a -> IO a
OpenGL Graphics.Rendering.OpenGL.GL.CoordTrans
Push the current matrix stack down by one, duplicating the current matrix, excute the given action, and pop the current matrix stack, replacing the current matrix with the one below it on the stack (i.e. restoring it to its previous state). The returned value is that of the given action. Note that a round-trip to the server is probably required. For a more efficient version, see unsafePreservingMatrix.
unsafePreservingMatrix :: IO a -> IO a
OpenGL Graphics.Rendering.OpenGL.GL.CoordTrans
A more efficient, but potentially dangerous version of preservingMatrix: The given action is not allowed to throw an exception or change the current matrix mode permanently.
withSocketsDo :: IO a -> IO a
network Network.Socket.Internal, network Network.Socket, network Network
On Windows operating systems, the networking subsystem has to be initialised using withSocketsDo before any networking operations can be used. eg. > main = withSocketsDo $ do {...} Although this is only strictly necessary on Windows platforms, it is harmless on other platforms, so for portability it is good practice to use it all the time.
deleteMax :: IntMap a -> IntMap a
containers Data.IntMap.Strict, containers Data.IntMap.Lazy
O(min(n,W)). Delete the maximal key. Returns an empty map if the map is empty. Note that this is a change of behaviour for consistency with Map  versions prior to 0.5 threw an error if the IntMap was already empty.
deleteMin :: IntMap a -> IntMap a
containers Data.IntMap.Strict, containers Data.IntMap.Lazy
O(min(n,W)). Delete the minimal key. Returns an empty map if the map is empty. Note that this is a change of behaviour for consistency with Map  versions prior to 0.5 threw an error if the IntMap was already empty.
unQ :: Q a -> forall m. Quasi m => m a
template-haskell Language.Haskell.TH.Syntax
reverse :: Seq a -> Seq a
containers Data.Sequence
O(n). The reverse of a sequence.
deleteMax :: Set a -> Set a
containers Data.Set
O(log n). Delete the maximal element. Returns an empty set if the set is empty.
deleteMin :: Set a -> Set a
containers Data.Set
O(log n). Delete the minimal element. Returns an empty set if the set is empty.
normalizeHostHeader :: Request ty -> Request ty
HTTP Network.HTTP.Base
Deprecated: Please use Network.HTTP.Base.normalizeRequest instead
joinPath :: [FilePath] -> FilePath
filepath System.FilePath.Windows, filepath System.FilePath.Posix
Join path elements back together. > Valid x => joinPath (splitPath x) == x > joinPath [] == "" > Posix: joinPath ["test","file","path"] == "test/file/path"
cat :: [Doc] -> Doc
pretty Text.PrettyPrint.HughesPJ, pretty Text.PrettyPrint
Either hcat or vcat.
cat :: [Doc] -> Doc
template-haskell Language.Haskell.TH.PprLib
Either hcat or vcat
fcat :: [Doc] -> Doc
pretty Text.PrettyPrint.HughesPJ, pretty Text.PrettyPrint
"Paragraph fill" version of cat.
