Top 14 Haskell Effect Projects

  • kitten

    A statically typed concatenative systems programming language.

    Project mention: my cat is installing debian 10 | reddit.com/r/linuxmemes | 2021-10-20

    Kitten lang

  • fused-effects

    A fast, flexible, fused effect system for Haskell

    Project mention: Where's more discussion of the designs of effect systems? | reddit.com/r/ProgrammingLanguages | 2021-11-17

    Languages such as Koka only support algebraic effects, not scoping operations such as catch and listen. The Effect Handlers in Scope paper introduces scoping operations, which lead to the Haskell libraries fused-effects and polysemy, but they turned out to have some weird semantics. eff is her effort to fix that.

  • capability

    Extensional capabilities and deriving combinators

    Project mention: Haskell doesn't make sense without pure functions | reddit.com/r/haskell | 2021-10-02
  • lawvere

    A categorical programming language with effects

    Project mention: Lawvere: A categorical programming language with effects | news.ycombinator.com | 2021-07-18
  • extensible-effects

    Extensible Effects: An Alternative to Monad Transformers

    Project mention: A solid GUI Framework for Haskell? | reddit.com/r/haskell | 2021-06-27

    Why do you need a GUI library, if you can write your application using extensible effects frameworks, just choose any and enjoy!

  • avail

    Low-overhead effect management for concrete monads

    Project mention: Effect is a phantom (or, the redundant constraint pattern) | reddit.com/r/haskell | 2021-09-14

    Yes, this is what I did in the WIP availability library, except that I used the reflection trick instead of ImplicitParams. Conceptually they are the same.

  • effet

    An effect system based on type classes, written in Haskell.

    Project mention: Monthly Hask Anything (May 2021) | reddit.com/r/haskell | 2021-05-05

    You may also be interested in effet, which is an mtl-like effect system which tries to overcome the limitations of mtl.

    Yes, I just uploaded it to https://github.com/typedbyte/program.
