This package provides functions to fork threads and wait for their result, whether it's an exception or a normal value. Besides waiting for the termination of a single thread this package also provides functions to wait for a group of threads to terminate. This package is similar to the threadmanager, async and spawn packages. The advantages of this package are:

• Simpler API.

• More efficient in both space and time.

• No space-leak when forking a large number of threads.

• Correct handling of asynchronous exceptions.

• GHC specific functionality like forkOn and forkIOWithUnmask.

This package provides memory abstractions, such as chunk of memory, polymorphic byte array management and manipulation functions. It contains a polymorphic byte array abstraction and functions similar to strict ByteString, different type of byte array abstraction, raw memory IO operations (memory set, memory copy, ..) and more

This library provides Pure Haskell solver routines for use by the diagrams framework. It currently includes routines for finding real roots of low-degree (n < 5) polynomials, and solving tridiagonal and cyclic tridiagonal linear systems.

This package provides a data type for colours and transparency. Colours can be blended and composed. Various colour spaces are supported. A module of colour names ("Data.Colour.Names") is provided.

This package provides Haskell bindings to the SDL2_gfx graphics library.

This package provides a Haskell library including a couple of different implementations of mutable hash tables in the ST monad, as well as a typeclass abstracting their common operations, and a set of wrappers to use the hash tables in the IO monad.

This package provides functions to marshal and unmarshal pandoc document types to and from Lua. . The values of most types are pushed to pandoc as "userdata" objects that wrap a stable pointer to the Haskell value; these objects come with methods to access and modify their properties. . Sequences are pushed as normal Lua tables, but are augmented with convenience functions.

This package provides a compatibility layer for using GHC call stacks with different versions of the compiler.

IWlib is a thin Haskell binding to the iw C library. It provides information about the current wireless network connections, and adapters on supported systems.

This package defines new symbols for a number of functions, operators and types in the base package. All symbols are documented with their actual definition and information regarding their Unicode code point. They should be completely interchangeable with their definitions. For further Unicode goodness you can enable the UnicodeSyntax language extension. This extension enables Unicode characters to be used to stand for certain ASCII character sequences, i.e. → instead of ->, ∀ instead of forall and many others.

This library is simply a collection of linear-algebra related modules split from the statistics library.

This package exports a module which is the recommended starting point for using microlens if you aren't trying to keep your dependencies minimal. By importing Lens.Micro.Platform you get all functions and instances from microlens, microlens-th, microlens-mtl, microlens-ghc, as well as instances for Vector, Text, and HashMap. The minor and major versions of microlens-platform are incremented whenever the minor and major versions of any other microlens package are incremented, so you can depend on the exact version of microlens-platform without specifying the version of microlens you need. This package is a part of the microlens family; see the readme on Github.

This package provides a simple (but internally ugly) memoization function.

The haskell-src package provides support for manipulating Haskell source code. The package provides a lexer, parser and pretty-printer, and a definition of a Haskell abstract syntax tree (AST). Common uses of this package are to parse or generate Haskell 98 code.

This Haskell library provides a Lua module to work with file paths in a platform independent way.

Haskell has excellect handling of unicode, the Char type covers all unicode chars. Unfortunately, there's no possibility to read or write something to the outer world in an encoding other than ascii due to the lack of support for encodings. This library should help with that.

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

This package implements a language similar to YAML or JSON but with fewer special cases and fewer dependencies. It emphasizes layout structure for sections and lists, and requires quotes around strings.

Chell is a simple and intuitive library for automated testing. It natively supports assertion-based testing, and can use companion libraries such as chell-quickcheck to support more complex testing strategies.

SDL_image is an image file loading library. It loads images as SDL surfaces, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, XCF, XPM, XV.

The naive @foldl (\acc d -> acc * 10 + d) 0@ is expensive (quadratic!) for large @Integer@s. This package provides sub-quadratic implementation.

The threadDelay and timeout functions from the Haskell base library use the bounded Int type for specifying the delay or timeout period. This package provides alternative functions which use the unbounded Integer type.

This package contains the Control.Monad.Fail module providing the MonadFail class that became available in base-4.9.0.0 for older base package versions. This package turns into an empty package when used with GHC versions which already provide the Control.Monad.Fail module.

The Glasgow Haskell Compiler (GHC) is a state-of-the-art compiler and interactive environment for the functional language Haskell.
