This package provides a simple type class for converting values of different string types into values of other string types.

This package provides a simple logging abstraction that allows multiple back-ends.

This library provides a wrapper to mmap, allowing files or devices to be lazily loaded into memory as strict or lazy ByteStrings, ForeignPtrs or plain Ptrs, using the virtual memory subsystem to do on-demand loading.

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 the Network.Multicast Haskell module for sending UDP datagrams over multicast (class D) addresses.

SDL_image is an image file loading library. It loads images as SDL surfaces, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, XCF, XPM, XV.

This package makes it possible to define schemas for use when loading configuration files using the config-value format. These schemas can be used to process a configuration file into a Haskell value or to automatically generate documentation for the file format.

The Newtype typeclass represents the packing and unpacking of a newtype, and allows you to operate under that newtype with functions such as ala. Generics support was added in version 0.4, making this package a full replacement for the original newtype package, and an alternative to newtype-th.

Lifted-base exports IO operations from the base library lifted to any instance of MonadBase or MonadBaseControl. Note that not all modules from base are converted yet. The package includes a copy of the monad-peel test suite written by Anders Kaseorg.

regex-applicative is a Haskell library for parsing using regular expressions. Parsers can be built using Applicative interface.

This Haskell package is an abstract interface only. It provides a number of type clasess, but not an implementation. The type classes separate different levels of Par functionality. See the Control.Monad.Par.Class module for more details.

The mockery package provides support functions for automated testing.

Takes an error-throwing expression and puts it back in the Maybe it belongs in.

Note that this suffers from the https://ghc.haskell.org/trac/ghc/ticket/5902. Buyer beware.

This library provides support for parsing and generating BitTorrent files.

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.

This library provides the natural numbers for Haskell.

Atomically write to a file on POSIX-compliant systems while preserving permissions. mv is an atomic operation. This makes it simple to write to a file atomically just by using the mv operation. However, this will destroy the permissions on the original file. This library preserves permissions while atomically writing to a file.

This package provides ANSI terminal support for Haskell. It allows cursor movement, screen clearing, color output showing or hiding the cursor, and changing the title.

This package provides both mutable and immutable Bloom filter data types, along with a family of hash functions and an easy-to-use interface.

Simple DirectMedia Layer (libSDL) is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."

This package provides basic types for representing XML documents.

The YAML 1.2 format provides a much richer data-model and feature-set than the JavaScript Object Notation format. However, sometimes it's desirable to ignore the extra capabilities and treat YAML as if it was merely a more convenient markup format for humans to write JSON data. To this end this module provides a compatibility layer atop ghc-hsyaml ,which allows decoding YAML documents in the more limited JSON data-model while also providing convenience by reusing ghc-aeson's FromJSON instances for decoding the YAML data into native Haskell data types.

This library tries to call minimum system calls which are the bottleneck of web servers.

This package provides a Haskell library including a Storable instance for Complex which is binary compatible with C99, C++ and Fortran complex data types.
