Haskell Control

Open-source Haskell projects categorized as Control

Top 23 Haskell Control Projects

  • rio-orphans

    A standard library for Haskell (by commercialhaskell)

  • transient

    A full stack, reactive architecture for general purpose programming. Algebraic and monadically composable primitives for concurrency, parallelism, event handling, transactions, multithreading, Web, and distributed computing with complete de-inversion of control (No callbacks, no blocking, pure state)

  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Platform where developers build real-time applications for analytics, IoT and cloud-native services. Easy to start, it is available in the cloud or on-premises.

  • fused-effects

    A fast, flexible, fused effect system for Haskell

  • pipes

    Compositional pipelines (by Gabriella439)

  • funflow

    Functional workflows

    Project mention: Is there anything like funflow for rust? | reddit.com/r/rust | 2022-10-20

    funflow is a cool library for writing "workflows", but basically it's a library that implements caching. So if you have a process that reads a file A, does transformation A → B, then does B → C, then C → D, then writes D to disk, each step of that will be cached to disk and you won't need to redo the A → B step if your program crashes during the B → C step.

  • apecs

    a fast, extensible, type driven Haskell ECS framework for games

    Project mention: I want to make a game in Haskell to surprise my boyfriend, but don’t know where to start. | reddit.com/r/haskell | 2023-01-22

    There's an apecs-gloss tutorial here that is a simple Shmup.

  • mtl

    The Monad Transformer Library

    Project mention: Deprecating Safe Haskell, or heavily investing in it? | reddit.com/r/haskell | 2022-12-28

    The most recent real case I remember is https://github.com/haskell/mtl/issues/110, which could ended badly.

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

  • machines

    Networks of composable stream transducers

  • recursion-schemes

    Generalized bananas, lenses and barbed wire

    Project mention: Science of Recursion | reddit.com/r/AskScienceDiscussion | 2022-09-28

    In a programming context, recursion schemes can be used to write recursive (or corecursive) functions, by automating/abstracting away the common boilerplate part of actually doing the recursion. They take the form of polymorphic higher-order functions, which can be imported from a library like this classic one.

  • record

    Anonymous records

  • freer-simple

    A friendly effect system for Haskell

  • capability

    Extensional capabilities and deriving combinators

  • auto

    Haskell DSL and platform providing denotational, compositional api for discrete-step, locally stateful, interactive programs, games & automations. http://hackage.haskell.org/package/auto (by mstksg)

  • extensible-effects

    Extensible Effects: An Alternative to Monad Transformers

  • hask

    Category theory for Haskell with a lens flavor (you need GHC 7.8.3, not 7.8.2 to build this!)

  • free

    free monads (by ekmett)

    Project mention: Is this meta-authentication system possible in Haskell | reddit.com/r/haskell | 2022-04-10

    If you want me to go into more detail after you've given it a go, let me know. There are a few free monad libraries out there. I think the best place to start is https://hackage.haskell.org/package/free, because it is the least cushy library, and so you can learn how they work internally etc. Later you might try algebraic effects as a backup.

  • ComonadSheet

    A library for expressing "spreadsheet-like" computations with absolute and relative references, using fixed-points of n-dimensional comonads.

  • foldl

    Composable, streaming, and efficient left folds

    Project mention: How lazy do push streams need to be? | reddit.com/r/ocaml | 2022-08-03

    Re Haskell Foldl: do you mean it doesn't support finite streams? Because the limitation of Foldl is precisely the fact that it is strict and doesn't support early termination. See https://github.com/Gabriella439/foldl/issues/85

  • unliftio

    The MonadUnliftIO typeclass for unlifting monads to IO

    Project mention: How introduce `ResourceT` into my stack | reddit.com/r/haskell | 2022-10-14

    Possibly interesting thread here: https://github.com/fpco/unliftio/issues/68

  • transient-universe

    A Cloud monad based on transient for the creation of Web and reactive distributed applications that are fully composable, where Web browsers are first class nodes in the cloud

  • safe-exceptions

    Safe, consistent, and easy exception handling

    Project mention: Spooky Masks and Async Exceptions | reddit.com/r/haskell | 2022-10-30

    In case anyone is interested, there's a long discussion on this ticket. Still hoping somebody will respond to my comment.

  • abstract-par

  • these

    An either-or-both data type, with corresponding hybrid error/writer monad transformer.
