C->Haskell assists in the development of Haskell bindings to C libraries. It extracts interface information from C header files and generates Haskell code with foreign imports and marshaling. Unlike writing foreign imports by hand (or using hsc2hs), this ensures that C functions are imported with the correct Haskell types.

The functional graph library, FGL, is a collection of type and function definitions to address graph problems. The basis of the library is an inductive definition of graphs in the style of algebraic data types that encourages inductive, recursive definitions of graph algorithms.

This Haskell package aims to be an RFC3986 compliant URI parser that uses ByteStrings for parsing and representing the URI data.

This package provides a pure Haskell client library for the Music Player Daemon.

ghc-doctest-driver-gen is a Doctest's driver file generator. It lets you automatically generate driver file for Doctest's Cabal integration.

This library provides Comonads for Haskell.

This package enables users to expand type synonyms in Template Haskell abstract syntax trees (ASTs).

GLib is a collection of C data structures and utility functions for the GObject system, main loop implementation, for strings and common data structures dealing with Unicode. This package only binds as much functionality as required to support the packages that wrap libraries that are themselves based on GLib.

Provides an efficient Haskell implementation of Peano numbers

This package allows you to have a README.md that at the same time is a literate Haskell program.

This library provides mechanisms to efficiently run periodic, on-demand actions in Haskell.

This package defines a class, Hashable, for types that can be converted to a hash value. This class exists for the benefit of hashing-based data structures. The package provides instances for basic types and a way to combine hash values.

This Haskell library algorithms for vector arrays.

This package provides Type-level booleans.

This package provides Haskell bindings to SDL2_ttf C++ library.

This Haskell package provides additional data structures, and other added capabilities layered on top of the Par monad.

Checkers wraps up the expected properties associated with various standard type classes as QuickCheck properties. It also provides some morphism properties, arbitrary instances, and generator combinators for common data types.

Cairo is a library to render high quality vector graphics. There exist various backends that allows rendering to Gtk windows, PDF, PS, PNG and SVG documents, amongst others.

This Haskell package provides the core MonadUnliftIO typeclass, a number of common instances, and a collection of common functions working with it.

This library provides Control.Lens. The combinators in Control.Lens provide a highly generic toolbox for composing families of getters, folds, isomorphisms, traversals, setters and lenses and their indexed variants.

PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. Unlike many general-purpose RNGs, they are also hard to predict. . This library implements bindings to the standard C implementation. This includes the standard, unique, fast and single variants in the pcg family. There is a pure implementation that can be used as a generator with the random package as well as a faster primitive api that includes functions for generating common types. . The generators in this module are suitable for use in parallel but make sure threads don't share the same generator or things will go horribly wrong.

Wrapper for the Data.Version.Version Haskell type.

The zip-archive library provides functions for creating, modifying, and extracting files from zip archives in Haskell.

This package defines an Active abstraction for time-varying values with finite start and end times. It is used for describing animations within the diagrams framework.
