This package attempts to provide support for using Amazon Web Services like S3 (storage), SQS (queuing) and others to Haskell programmers. The ultimate goal is to support all Amazon Web Services.

This package provides the tldr command and a Haskell client library allowing users to update and view tldr pages from a shell. The tldr pages are a community effort to simplify the man pages with practical examples.

A rich drop-in replacement for base. For details and documentation please visit the project's home page.

This module allows tokens produced by skylighting-core to be rendered as LaTeX macros.

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 profides a class for encoding and decoding UTF8 strings with instances for several common types. It also includes several functions for working with UTF8. It aims to be lightweight, depending only on Base and including only one module.

This package provides instances for QuickCheck's \"Arbitrary\" typeclass.

This package provides pure-Haskell utilities for dealing with XML with the conduit package.

The doctest program checks examples in source code comments. It is modeled after doctest for Python (<https://docs.python.org/3/library/doctest.html>). . Documentation is at <https://github.com/martijnbastiaan/doctest-parallel#readme>.

OpenGLRaw is a raw Haskell binding for the OpenGL 4.5 graphics system and lots of OpenGL extensions. It is basically a 1:1 mapping of OpenGL's C API, intended as a basis for a nicer interface. OpenGLRaw offers access to all necessary functions, tokens and types plus a general facility for loading extension entries. The module hierarchy closely mirrors the naming structure of the OpenGL extensions, making it easy to find the right module to import. All API entries are loaded dynamically, so no special C header files are needed for building this package. If an API entry is not found at runtime, a userError is thrown.

This Haskell package lets you automatically generate lenses for data types; code was extracted from the lens package, and therefore generated lenses are fully compatible with ones generated by lens (and can be used both from lens and microlens).

This package provides a type-safe tool for generating XML code via quasi-quoting built on top of ghc-shakespeare.

Provides default instances for types from the containers package.

This package provides a canonical anonymous 1-tuple type missing from Haskell for attaching typeclass instances.

There is also the OneTuple package which by using a boxed data-type provides a 1-tuple type which has laziness properties which are more faithful to the ones of Haskell's native tuples; whereas the primary purpose of Only is to provide the traditionally so named type-wrapper for attaching typeclass instances.

Compatibility layer for Data.Array.Byte providing boxed wrappers for ByteArray and MutableByteArray and relevant instances for GHC < 9.4.

This package defines a class for types with a default value, and provides instances for types from the base, containers, dlist and old-locale packages.

This Haskell package was originally present in classy-prelude.

MissingH is a library of all sorts of utility functions for Haskell programmers. It is written in pure Haskell and thus should be extremely portable and easy to use.

This library provides exception safe semaphores that can be used in place of QSem, QSemN, and SampleVar, all of which are not exception safe and can be broken by killThread.

LeanCheck support for test-framework. This package can be used to incorporate LeanCheck tests into test-framework test suites.

This package provides distributive functors for Haskell. Dual to Traversable.

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.

GHC 7.4 introduced a new casMutVar PrimOp which is difficult to use safely, because pointer equality is a highly unstable property in Haskell. This library provides a safer method based on the concept of Tickets.

This package addresses the 'configuration problem' which is propagating configurations that are available at run-time, allowing multiple configurations to coexist without resorting to mutable global variables or System.IO.Unsafe.unsafePerformIO.
