This library provides an interface to GSL special functions for Haskell.

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

This Haskell library provides a Template Haskell deriver for unboxed vectors, given a pair of coercion functions to and from some existing type with an Unbox instance.

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 a backend for the ghc-persistent library using the ghc-postgresql-simple package.

The HMatrix package provides a Haskell library for dealing with linear systems, matrix decompositions, and other numerical computations based on BLAS and LAPACK.

This package provides instances to push and receive any datatype encodable as JSON to and from the Lua stack.

Haskell library for parsing of ISO 8601 dates, originally from aeson.

This package provides several functions to quickly search for substrings in strict or lazy ByteStrings. It also provides functions for breaking or splitting on substrings and replacing all occurrences of a substring (the first in case of overlaps) with another.

Provides Default instances for types from the old-locale package.

Provides Arbitrary instances for fgl graphs to avoid adding a QuickCheck dependency for fgl whilst still making the instances available to others. Also available are non-fgl-specific functions for generating graph-like data structures.

This package contains functions (like view or +=) which work on MonadReader, MonadWriter, and MonadState from the mtl package. This package is a part of the microlens family; see the readme on Github.

D-Bus is a simple, message-based protocol for inter-process communication, which allows applications to interact with other parts of the machine and the user's session using remote procedure calls. D-Bus is a essential part of the modern Linux desktop, where it replaces earlier protocols such as CORBA and DCOP. This library is an implementation of the D-Bus protocol in Haskell. It can be used to add D-Bus support to Haskell applications, without the awkward interfaces common to foreign bindings.

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

The mockery package provides support functions for automated testing.

A library for generating concise pretty printers based on precedence rules.

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').

SDL_mixer is a sample multi-channel audio mixer library. It supports any number of simultaneously playing channels of 16 bit stereo audio, plus a single channel of music, mixed by the popular MikMod MOD, Timidity MIDI, Ogg Vorbis, and SMPEG MP3 libraries.

This package provides low-dependency functionality commonly needed by various Haskell streaming data libraries, such as conduit and pipes.

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

This package provides a mid-Level PostgreSQL client library, forked from ghc-mysql-simple.

Boxes is a pretty-printing library for laying out text in two dimensions, using a simple box model.

Expose Haskell objects to Lua with an object oriented interface.

This package contains basic definitions related to indexed profunctors. These are primarily intended as internal utilities to support the optics and generic-lens package families.
