This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the zlib C library so it has high performance. It supports the zlib, gzip and raw compression formats. It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full zlib feature set.

This package provides Haskell bindings to your system's native wcwidth and a command line tool to examine the widths assigned by it. The command line tool can compile a width table to Haskell code that assigns widths to the Char type.

Set- and Map-like types that remember the order elements were inserted

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

Parse jira wiki text into an abstract syntax tree for easy transformation to other formats.

This package includes Hakell modules providing various helper functions for Lists, Maybes, Tuples, Functions.

Easy-to-write domain-specific language (DSL) for building Scalable Vector Graphics (SVG).

This Haskell library provides pointed and copointed data types.

This package provides a Pure Haskell implementation of the SplitMix pseudorandom number generator. SplitMix is a "splittable" pseudorandom number generator that is quite fast: 9 64-bit arithmetic/logical operations per 64 bits generated. SplitMix is tested with two standard statistical test suites (DieHarder and TestU01, this implementation only using the former) and it appears to be adequate for "everyday" use, such as Monte Carlo algorithms and randomized data structures where speed is important. In particular, it should not be used for cryptographic or security applications, because generated sequences of pseudorandom values are too predictable (the mixing functions are easily inverted, and two successive outputs suffice to reconstruct the internal state).

This package provides a library implementing the XDG Base Directory spec.

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

This package provides a simple applicative parser in Parsec style.

Derive instances of Arbitrary for QuickCheck, with various options to customize implementations.

Automating the arbitrary boilerplate also ensures that when a type changes to have more or fewer constructors, then the generator either fixes itself to generate that new case (when using the uniform distribution) or causes a compilation error so you remember to fix it (when using an explicit distribution).

This package also offers a simple (optional) strategy to ensure termination for recursive types: make Test.QuickCheck.Gen's size parameter decrease at every recursive call; when it reaches zero, sample directly from a trivially terminating generator given explicitly (genericArbitraryRec and withBaseCase) or implicitly (genericArbitrary').

This library provides core modules of a markup combinator library for Haskell.

This package provides an URI manipulation interface. In network-2.6 the Network.URI module was split off from the network package into this package.

The conduit package itself maintains relative small dependencies. The purpose of this package is to collect commonly used utility functions wrapping other library dependencies, without depending on heavier-weight dependencies. The basic idea is that this package should only depend on haskell-platform packages and conduit.

This library is for working with \".tar\" archive files. It can read and write a range of common variations of the tar archive format including V7, POSIX USTAR and GNU formats. It provides support for packing and unpacking portable archives. This makes it suitable for distribution but not backup because details like file ownership and exact permissions are not preserved. It also provides features for random access to archive content using an index.

This package provides utilities and combinators for parsing command line options in Haskell.

This package provides functions to prevent or capture writing to stdout and other handles.

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.

This library provides a utility function liftType, which accepts a type application argument and returns the Template Haskell Type representation of it.

This package provides the core modules underlying diagrams, an embedded domain-specific language for compositional, declarative drawing.

This library provides an easy way to define command line parsers.

This Haskell package provides extras for the ghc-contravariant package.
