Name: io-streams Version: 1.5.2.2 License: BSD3 License-file: LICENSE Category: Data, Network, IO-Streams Build-type: Simple Maintainer: Gregory Collins Cabal-version: >= 1.10 Synopsis: Simple, composable, and easy-to-use stream I/O Tested-With: GHC == 9.4.1 GHC == 9.2.4 GHC == 9.0.2 GHC == 8.10.7 GHC == 8.8.4 GHC == 8.6.5 GHC == 8.4.4 GHC == 8.2.2 GHC == 8.0.2 GHC == 7.10.3 GHC == 7.8.4 GHC == 7.6.3 GHC == 7.4.2 Bug-Reports: https://github.com/snapframework/io-streams/issues Description: /Overview/ . The io-streams library contains simple and easy-to-use primitives for I/O using streams. Most users will want to import the top-level convenience module "System.IO.Streams", which re-exports most of the library: . @ import System.IO.Streams (InputStream, OutputStream) import qualified System.IO.Streams as Streams @ . For first-time users, @io-streams@ comes with an included tutorial, which can be found in the "System.IO.Streams.Tutorial" module. . /Features/ . The @io-streams@ user API has two basic types: @InputStream a@ and @OutputStream a@, and three fundamental I/O primitives: . @ \-\- read an item from an input stream Streams.read :: InputStream a -> IO (Maybe a) . \-\- push an item back to an input stream Streams.unRead :: a -> InputStream a -> IO () . \-\- write to an output stream Streams.write :: Maybe a -> OutputStream a -> IO () @ . Streams can be transformed by composition and hooked together with provided combinators: . @ ghci> Streams.fromList [1,2,3::Int] >>= Streams.map (*10) >>= Streams.toList [10,20,30] @ . Stream composition leaves the original stream accessible: . @ ghci> input \<- Streams.fromByteString \"long string\" ghci> wrapped \<- Streams.takeBytes 4 input ghci> Streams.read wrapped Just \"long\" ghci> Streams.read wrapped Nothing ghci> Streams.read input Just \" string\" @ . Simple types and operations in the IO monad mean straightforward and simple exception handling and resource cleanup using Haskell standard library facilities like 'Control.Exception.bracket'. . @io-streams@ comes with: . * functions to use files, handles, concurrent channels, sockets, lists, vectors, and more as streams. . * a variety of combinators for wrapping and transforming streams, including compression and decompression using zlib, controlling precisely how many bytes are read from or written to a stream, buffering output using bytestring builders, folds, maps, filters, zips, etc. . * support for parsing from streams using @attoparsec@. . * support for spawning processes and communicating with them using streams.
