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 pure Haskell client library for the Music Player Daemon.

Experimental Hspec support for testing WAI applications

This package provides Haskell modules to allow use of Accessor to access state in transformers State monad.

This package provides filtrable containers.

This package provides a library for parallel programming.

The package provides mutable and immutable bit arrays.

This Haskell library algorithms for vector arrays.

This package provides a simple compatibility shim that lets you work with both binary and cereal with one chunk of serialization code.

This package provides a Haskell module for creating 2D and 3D plots using gnuplot.

This library provides tools for fast Unicode 12.1.0 normalization in Haskell (normalization forms C, KC, D, and KD).

This package provides a small cross-platform library for reading and modifying the system clipboard. It uses xclip or xsel at runtime.

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 package provides a custom prelude with no dependencies apart from the base package.

Foundation has the following goals:

1. provide a base like sets of modules that provide a consistent set of features and bugfixes across multiple versions of GHC (unlike base).

2. provide a better and more efficient prelude than base's prelude.

3. be self-sufficient: no external dependencies apart from base;

4. provide better data-types: packed unicode string by default, arrays;

5. Numerical classes that better represent mathematical things (no more all-in-one Num);

6. I/O system with less lazy IO.

This package provides Haskell 98 groups. A group is a monoid with invertibility.

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.

This package provides a typeclass with a single function that is designed to help convert between different types: numeric values, dates and times, and the like. The conversions perform bounds checking and return a pure Either value. This means that you need not remember which specific function performs the conversion you desire.

This package provides Haskell bindings to SDL2_ttf C++ library.

A cross-platform library for retrieving information about disk space usage.

Old-time is a package for backwards compatibility with the old time library. For new projects, the newer time library is recommended.

Network recv based on buffer pools

This is only for use in developing libraries that should conform to the persistent interface, not for users of the persistent suite of database libraries.

This is a library for testing code involving bottoms or infinite values. For the underlying theory and a larger example involving use of QuickCheck, see the article "Chasing Bottoms A Case Study in Program Verification in the Presence of Partial and Infinite Values".

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.
