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. %package devel Summary: Haskell %{pkg_name} library development files Group: Development/Libraries/Other Requires: %{name} = %{version}-%{release} Requires: ghc-compiler = %{ghc_version} Requires(post): ghc-compiler = %{ghc_version} Requires(postun): ghc-compiler = %{ghc_version} %description devel This package provides the Haskell %{pkg_name} library development files. %prep %setup -q -n %{pkg_name}-%{version} %build %ghc_lib_build %install %ghc_lib_install %check %cabal_test %post devel %ghc_pkg_recache %postun devel %ghc_pkg_recache %files -f %{name}.files %defattr(-,root,root,-) %doc LICENSE %files devel -f %{name}-devel.files %defattr(-,root,root,-) %doc CONTRIBUTORS README.md changelog.md %changelog
