io-streams

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: 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: Streams can be transformed by composition and hooked together with provided combinators: Stream composition leaves the original stream accessible: 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.

io-streams is a tool in the Build Automation category of a tech stack.
