Haskell Dependent Types

Open-source Haskell projects categorized as Dependent Types

Top 21 Haskell Dependent Type Projects

  • Agda

    Agda is a dependently typed programming language / interactive theorem prover.

    Project mention: What are the current hot topics in type theory and static analysis? | reddit.com/r/ProgrammingLanguages | 2023-05-08

    Most of the proof assistants out there: Lean, Coq, Dafny, Isabelle, F*, Idris 2, and Agda. And the main concepts are dependent types, Homotopy Type Theory AKA HoTT, and Category Theory. Warning: HoTT and Category Theory are really dense, you're going to really need to research them.

  • singletons

    Fake dependent types in Haskell using singletons

    Project mention: Is it possible to create singleton types for datatype wrapping String/Text? | reddit.com/r/haskell | 2022-07-06
  • CodiumAI

    TestGPT | Generating meaningful tests for busy devs. Get non-trivial tests (and trivial, too!) suggested right inside your IDE, so you can code smart, create more value, and stay confident when you push.

  • cubical

    Implementation of Univalence in Cubical Sets (by simhu)

  • tensor-safe

    A Haskell framework to define valid deep learning models and export them to other frameworks like TensorFlow JS or Keras.

  • first-class-families

    First-class type families

    Project mention: Foldr type level implementation | reddit.com/r/haskellquestions | 2023-03-30

    First class families is the approach I'm familiar with, although it can feel a bit heavy-handed. There's a chapter in Thinking with Types about how to use fcf.

  • hoq

    A language based on homotopy type theory with an interval

  • type-natural

    Type-level well-kinded natural numbers.

  • ONLYOFFICE

    ONLYOFFICE Docs — document collaboration in your environment. Powerful document editing and collaboration in your app or environment. Ultimate security, API and 30+ ready connectors, SaaS or on-premises

  • eliminators

    Dependently typed elimination functions using singletons

  • helf

    Haskell implementation of the Edinburgh Logical Framework

  • lens-typelevel

    Type-level lenses using singletons because why not

  • agda2lagda

    Simple conversion from Agda text to literate Agda text.

  • decidable

    Combinators for manipulating dependently-typed predicates.

  • sized

    Sized sequence data-types

  • agda-unused

    Check for unused code in an Agda project.

  • agda-snippets

    Library and tool to render the snippets in literate Agda files to hyperlinked HTML, leaving the rest of the text untouched.

  • singletons-presburger

    Presburger arithmetic solver for built-in type-level naturals

  • Sit

    Prototypical type checker for Type Theory with Sized Natural Numbers (by andreasabel)

  • open-typerep

    Open type representations and dynamic types

    Project mention: Extensible ASTs with extensible types | reddit.com/r/haskell | 2022-12-28
  • fcf-containers

    fcf-containers add tools that can be used with first-class-families

  • instance-map

    Haskell dependent types the ugly and brute force way

  • list-witnesses

    Inductive dependently-typed witnesses for working with type-level lists.
