This library provides higher order versions of Prelude classes to ease programming with polymorphic recursion and reduce UndecidableInstances.

This package provides strict versions of some standard Haskell data types, such as pairs, Maybe and Either. It also contains strict IO operations.

The ghc-ini Haskell library lets programmers quickly and easily read and write configuration files in the simple INI format.

Provides an efficient Haskell implementation of Peano numbers

This package provides semigroups for Haskell. In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation. A semigroup generalizes a monoid in that there might not exist an identity element. It also (originally) generalized a group (a monoid with all inverses) to a type where every element did not have to have an inverse, thus the name semigroup.

This library provides a datatype which can be interpreted by apply-refact. It exists as a separate library so that applications can specify refactorings without depending on GHC.

GLURaw is a raw Haskell binding for the GLU 1.3 OpenGL utility library. It is basically a 1:1 mapping of GLU's C API, intended as a basis for a nicer interface.

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.

FoldMap lists are lists represented by their foldMap function. FoldMap lists have O(1) cons, snoc and append, just like DLists, but other operations might have favorable performance characteristics as well. These wild claims are still completely unverified though.

This package provides an interface to the directory package for users of path. It also implements some missing stuff like recursive scanning and copying of directories, working with temporary files/directories, and more.

This package provides a compatibility layer providing Binary instances for strict and lazy text types for versions older than 1.2.1 of the text package.

GNU ncurses is a library for creating command-line application with pseudo-graphical interfaces. This package is a nice, modern binding to GNU ncurses.

Haskell-Source with Extensions (HSE, haskell-src-exts) is an extension of the standard haskell-src package, and handles most registered syntactic extensions to Haskell. All extensions implemented in GHC are supported. Apart from these standard extensions, it also handles regular patterns as per the HaRP extension as well as HSX-style embedded XML syntax.

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

Lets multiple threads and external processes concurrently output to the console, without it getting all garbled up.

Built on top of that is a way of defining multiple output regions, which are automatically laid out on the screen and can be individually updated by concurrent threads. Can be used for progress displays etc.

This package turn Data.Serialize Gets and Puts into Sources, Sinks, and Conduits.

Expose Haskell objects to Lua with an object oriented interface.

This library provides profunctors for Haskell.

This package provides type classes, a monad and a monad transformer that support unchecked extensible exceptions as well as asynchronous exceptions. It is compatible with the transformers package.

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.

GLib is a collection of C data structures and utility functions for the GObject system, main loop implementation, for strings and common data structures dealing with Unicode. This package only binds as much functionality as required to support the packages that wrap libraries that are themselves based on GLib.

Text.Regex.Base provides the interface API for regex-posix, regex-pcre, regex-parsec, regex-tdfa, regex-dfa.

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

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