  1. foldMany :: forall t (m :: Type -> Type) a b . (IsStream t, Monad m) => Fold m a b -> t m a -> t m b

    streamly Streamly.Prelude

    Apply a Fold repeatedly on a stream and emit the fold outputs in the output stream. To sum every two contiguous elements in a stream: 

    >>> f = Fold.take 2 Fold.sum

>>> Stream.toList $ Stream.foldMany f $ Stream.fromList [1..10]
[3,7,11,15,19]
    On an empty stream the output is empty: 
    >>> Stream.toList $ Stream.foldMany f $ Stream.fromList []
[]
    Note Stream.foldMany (Fold.take 0) would result in an infinite loop in a non-empty stream.

  2. unfoldMany :: forall t (m :: Type -> Type) a b . (IsStream t, Monad m) => Unfold m a b -> t m a -> t m b

    streamly Streamly.Prelude

    Like concatMap but uses an Unfold for stream generation. Unlike concatMap this can fuse the Unfold code with the inner loop and therefore provide many times better performance.

  3. parseAnyfromText :: N3Parser a -> Maybe QName -> Text -> Either String a

    swish Swish.RDF.Parser.N3

    Function to supply initial context and parse supplied term.

  4. manyTill :: Parser s a -> Parser s b -> Parser s [a]

    swish Swish.RDF.Parser.Utils

    Accept zero or more runs of the parser ending with the delimiter.

  5. skipMany :: Parser s a -> Parser s ()

    swish Swish.RDF.Parser.Utils

    Run the parser many times and ignore the result.

  6. skipMany1 :: Parser s a -> Parser s ()

    swish Swish.RDF.Parser.Utils

    Run the parser many1 times and ignore the result.

  7. xsdAnyURI :: ScopedName

    swish Swish.RDF.Vocabulary.XSD

    xsd:anyURI from http://www.w3.org/TR/xmlschema-2/#anyURI.

  8. autoAndRecordMany :: forall y f (handle :: Type -> Type) . (SampleFmt y, C y, Traversable f) => f FilePath -> SoundFmt y -> SoundSink handle y -> T y -> IO (f ExitCode)

    synthesizer-alsa Synthesizer.ALSA.Storable.Play

    Play a signal and write it to multiple files. The Functor f may be Maybe for no or one file to write, or [] for many files to write.

  9. many :: Alternative f => f a -> f [a]

    threepenny-gui Graphics.UI.Threepenny.Core

    Zero or more.

    Examples

    >>> many (putStr "la")
lalalalalalalalala... * goes on forever *

    >>> many Nothing
Just []

    >>> take 5 <$> many (Just 1)
* hangs forever *
    Note that this function can be used with Parsers based on Applicatives. In that case many parser will attempt to parse parser zero or more times until it fails.

  10. matchManyToOne :: (b -> a -> Bool) -> Pattern a -> Pattern b -> Pattern (Bool, b)

    tidal Sound.Tidal.Boot

    Mark values in the first pattern which match with at least one value in the second pattern.
