streamly: Streaming, dataflow programming and declarative concurrency
For upgrading to streamly-0.9.0+ please read the Streamly-0.9.0 upgrade guide.
Streamly is a standard library for Haskell that focuses on C-like performance, modular combinators, and streaming data flow model. Streamly consists of two packages, the streamly-core package provides functionality that depends only on boot libraries, and the streamly package provides additional functionality like concurrency, time, lifted exceptions, and networking. For unified documentation visit the streamly website.
Streamly provides unified, modular building blocks to build high-performance, concurrent, scalable applications in Haskell. Stream fusion optimizations in streamly enable exceptional modularity with high performance comparable to C. Streamly complements the Haskell base package, supplying additional functionality to quickly build general-purpose applications in Haskell. For high-level functionality built over streamly like streaming OS processes, shell programming, GNU coreutils, statistics, and compression libraries please see the streamly ecosystem packages.
Performance with modularity:
Performance on par with C (Benchmarks)
API close to standard Haskell lists (Examples)
Declarative concurrency with automatic scaling
Filesystem, fsnotify, network, and Unicode support included
Fast binary serialization (with optional JSON like features)
More functionality is provided via many (ecosystem packages)
Unified and powerful abstractions:
Unifies streams, arrays, folds, and parsers
Unifies
Data.List
,list-t
, andlogict
with streamingUnifies concurrency with standard streaming abstractions
Unifies reactive, time-domain programming with streaming
Unifies binary serialization and unboxed arrays
Interworks with other streaming libraries
