This package provides portable implementations of parts of the unix package. This package re-exports the unix package when available. When it isn't available, portable implementations are used.

This Haskell package contains code for generating high quality random numbers that follow either a uniform or normal distribution. The generated numbers are suitable for use in statistical applications.

The uniform PRNG uses Marsaglia's MWC256 (also known as MWC8222) multiply-with-carry generator, which has a period of 2^8222 and fares well in tests of randomness. It is also extremely fast, between 2 and 3 times faster than the Mersenne Twister.

This package turn Data.Serialize Gets and Puts into Sources, Sinks, and Conduits.

This package provides a library for generating 2D charts and plots, with backends provided by the Cairo and Diagrams libraries.

This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible. The library exposes a van Laarhoven interface. For an alternative interface, supporting an opaque optic type, see generic-optics.

This package provides tools to measure the memory usage of a Haskell value or function.

Language C is a Haskell library for the analysis and generation of C code. It features a complete, well-tested parser and pretty printer for all of C99 and a large set of GNU extensions.

This library provides adjunctions and representable functors for Haskell.

Happy is a parser generator for Haskell. Given a grammar specification in BNF, Happy generates Haskell code to parse the grammar. Happy works in a similar way to the yacc tool for C.

This package provides a fast, reliable priority queue implementation based on a binomial heap.

This library contains scalable timer functions provided by a timer manager.

Brick helps you write terminal user interfaces (TUIs). You write an event handler and a drawing function and the library does the rest.

This package contains helper functions on top of Template Haskell.

For example, functionExtractor extracts all functions after a regexp-pattern, which can be useful if you wish to extract all functions beginning with test (for a test framework) or all functions beginning with wc (for a web service).

This package provides state variables, which are references in the IO monad, like IORefs or parts of the OpenGL state.

vty is a terminal GUI library in the niche of ncurses, intended to be easy to use and to provide good support for common terminal types.

Simple DirectMedia Layer (libSDL) is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."

This package allows you to work with WAVE and RF64 files in Haskell.

This library provides various semigroups, specialized containers and a general map/reduce framework for Haskell.

This package provides a collection of Haskell functions for splitting lists into parts, akin to the split function found in several mainstream languages.

This package provides functions to marshal values from Haskell to Lua, and /vice versa/. . This package is part of HsLua, a Haskell framework built around the embeddable scripting language <https://lua.org Lua>.

Text.Regex.Base provides the interface API for regex-posix, regex-pcre, regex-parsec, regex-tdfa, regex-dfa.

The module Data.CaseInsensitive provides the CI type constructor which can be parameterised by a string-like type like: String, ByteString, Text, etc. Comparisons of values of the resulting type will be insensitive to cases.

This library provides phantom types for Haskell 98, to avoid having to unsafely pass dummy arguments.

Highlighting-kate is a syntax highlighting library with support for nearly one hundred languages. The syntax parsers are automatically generated from Kate syntax descriptions, so any syntax supported by Kate can be added. An (optional) command-line program is provided, along with a utility for generating new parsers from Kate XML syntax descriptions.
