  1. read :: Read a => String -> a

    base-compat Text.Read.Compat

    The read function reads input from a string, which must be completely consumed by the input process. read fails with an error if the parse is unsuccessful, and it is therefore discouraged from being used in real applications. Use readMaybe or readEither for safe alternatives.

    >>> read "123" :: Int
    123
    
    >>> read "hello" :: Int
    *** Exception: Prelude.read: no parse
    

  2. read :: Read a => String -> a

    hedgehog Hedgehog.Internal.Prelude

    The read function reads input from a string, which must be completely consumed by the input process. read fails with an error if the parse is unsuccessful, and it is therefore discouraged from being used in real applications. Use readMaybe or readEither for safe alternatives.

    >>> read "123" :: Int
    123
    
    >>> read "hello" :: Int
    *** Exception: Prelude.read: no parse
    

  3. read :: Read a => String -> a

    ghc GHC.Prelude.Basic

    The read function reads input from a string, which must be completely consumed by the input process. read fails with an error if the parse is unsuccessful, and it is therefore discouraged from being used in real applications. Use readMaybe or readEither for safe alternatives.

    >>> read "123" :: Int
    123
    
    >>> read "hello" :: Int
    *** Exception: Prelude.read: no parse
    

  4. read :: (Functor m, Read a) => Pipe String a m r

    pipes Pipes.Prelude

    Parse Readable values, only forwarding the value if the parse succeeds

  5. read :: InputStream a -> IO (Maybe a)

    io-streams System.IO.Streams

    Reads one value from an InputStream. Returns either a value wrapped in a Just, or Nothing if the end of the stream is reached.

  6. read :: InputStream a -> IO (Maybe a)

    io-streams System.IO.Streams.Core

    Reads one value from an InputStream. Returns either a value wrapped in a Just, or Nothing if the end of the stream is reached.

  7. read :: InputStream a -> IO (Maybe a)

    io-streams System.IO.Streams.Internal

    Reads one value from an InputStream. Returns either a value wrapped in a Just, or Nothing if the end of the stream is reached.

  8. read :: Read a => String -> a

    rio RIO.Partial

    The read function reads input from a string, which must be completely consumed by the input process. read fails with an error if the parse is unsuccessful, and it is therefore discouraged from being used in real applications. Use readMaybe or readEither for safe alternatives.

    >>> read "123" :: Int
    123
    
    >>> read "hello" :: Int
    *** Exception: Prelude.read: no parse
