TerraHS is a software component that enables the development of geographical applications in a functional language, using the data handling capabilities and spatial operations of TerraLib.

Alternative regular expression library for Haskell

This library for the Haskell programming language provides Video4Linux2 (V4L2) frame grabber operation functions. Requires GHC (Glasgow Haskell Compiler) and Linux kernel 2.6 header files.

An integrated development environment for the programming language haskell.

wikit is another wiki engine suited for small teams. It’s written in Haskell with using Yesod Web Framework. It’s cross platform and was designed to be running as a desktop service application servicing wiki articles and providing some basic capabilities in terms of searching and storing data. It’s perhaps most distinct feature is that it relies on backing Git distributed source control system. And keeps it’s articles in markdown format. Which makes it very easy to port out of the wiki and keep somewhere else if one would wish so, and vice versa, it allows to through bunch of existing documents in markdown format to be introduced into wiki and make available to your team.

Data.Array.Accelerate defines an embedded language of array computations for high-performance computing in Haskell. Computations on multi-dimensional, regular arrays are expressed in the form of parameterized collective operations (such as maps, reductions, and permutations). These computations are online-compiled and executed on a range of architectures. Accelerate is a free, general-purpose, open-source library that simplifies the process of developing software that targets massively parallel architectures including multicore CPUs and GPUs. Embedded in the advanced functional programming language Haskell, Accelerate programs are declarative, statically-typed, pure, functional, and ready to exploit all of the performance of modern parallel hardware. The combination of a strong type system, high-level code, and interactive development environment, allows you to develop code quickly with the confidence that it is correct.

aeson is a high-performance Haskell library for JSON parsing and encoding, optimized for speed and ease of use. It serves as a foundational tool in the Haskell ecosystem for handling JSON data efficiently. High-performance optimized for real-world workloads. Widely used and well-maintained community library. Compatible with popular frameworks and the Haskell web ecosystem. Easy-to-use API (e.g., FromJSON, ToJSON typeclasses). Fast JSON parsing and serialization.

An educational project aimed at illustrating programming language concepts and implementation techniques in different programming languages.

Alga is a library for algebraic construction and manipulation of graphs in Haskell. See this Haskell Symposium paper and the corresponding talk for the motivation behind the library, the underlying theory and implementation details. We can give semantics to the constructors in terms of the pair (V, E) of graph vertices and edges. Alga can handle graphs comprising millions of vertices and billions of edges in a matter of seconds, which is fast enough for many applications. We believe there is a lot of potential for improving the performance of the library, and this is one of our top priorities. If you come across a performance issue when using the library, please let us know.

This project intends to develop tools to enable MDA support for the formal modeling language Alloy.

An interpreter for the Argh! esoteric programming language in wxHaskell. The program allows one to load, edit, save, validate and run Argh! programs. It currently supports all commands except 'e' and 'E'. Documented using Haddock.

A command line tool that allows a semi-automated scientific articles management. It assumes an existence of a directory of a specific format in the file system. The tool interprets the data stored in the directory (called a repository), extend it via the usage of some automatic tools such as pdftotext, and search the text as well as some metadata.

A compiler which translated AspectFun program into Haskell.

Asterius is a Haskell toolchain that compiles to WebAssembly, enabling Haskell programs to run in the browser and other Wasm hosts. It builds on GHC, lowers Haskell code to WebAssembly modules, and links them with a lightweight JavaScript runtime for I/O, GC interaction, and host integration. The toolchain provides commands to build and link (ahc/ahc-link), bundle assets, and target both browser and Node environments. Interop is a core focus: Haskell functions can call into JavaScript and vice versa, making it feasible to combine Haskell logic with web APIs. Asterius aims to keep as much of Haskell’s runtime model as practical while delivering the portability and startup characteristics of Wasm. By bridging GHC and WebAssembly, it opens a path to reuse Haskell libraries on the client side without switching languages.

Brick is a Haskell terminal user interface (TUI) programming toolkit that enables developers to build rich, responsive terminal applications via a declarative model: you define a pure function that renders the UI from application state and supply state transition logic to handle events. brick exposes a declarative API. Unlike most GUI toolkits which require you to write a long and tedious sequence of widget creations and layout setup, brick just requires you to describe your interface using a set of declarative layout combinators. Event-handling is done by pattern-matching on incoming events and updating your application state. Under the hood, this library builds upon vty, so some knowledge of Vty will be necessary to use this library. Brick depends on vty-crossplatform, so Brick should work anywhere Vty works (Unix and Windows). Brick releases prior to 2.0 only support Unix-based systems.

BuddyScout is an interface between BuDDy (Binary Decision Diagram library) and GHC (Glasgow Haskell Compiler). It enables you to use the BDD library from within Haskell programs.

Cabal is a system for building and packaging Haskell libraries and programs. It defines a common interface for package authors and distributors to easily build their applications in a portable way. Cabal is part of a larger infrastructure for distributing, organizing, and cataloging Haskell libraries and programs. The term cabal can refer to either: cabal-the-spec (.cabal files), cabal-the-library (code that understands .cabal files), or cabal-the-tool (the cabal-install package which provides the cabal executable); usually folks are referring to cabal-the-tool when they say cabal. To install the cabal executable you can use ghcup (if you're using Linux), the Haskell Platform, install the cabal-install package from your distributions package manager (if using Linux or Mac), or download the source or prebuilt binary from the Download page.

Cryptographic currency implementing Ouroboros PoS protocol. The cardano-node is the top level for the node and aggregates the other components from other packages: consensus, ledger and networking, with configuration, CLI, logging and monitoring. The node no longer incorporates wallet or explorer functionality. The wallet backend and explorer backend are separate components that run in separate external processes that communicate with the node via local IPC. The new Cardano implementation consists of more granular components.

Music synthesizer based on cellular automata. Written in Haskell.
