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.
