This package implements an API for accessing the Domain Name Service (DNS) resolver service via the standard libresolv system library (whose API is often available directly via the standard libc C library) on Unix systems.

Expose Haskell objects to Lua with an object oriented interface.

An integration library for hspec and hedgehog.

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 Haskell package supports the definition of generic functions. Datatypes are viewed in a uniform, structured way: the choice between constructors is represented using an n-ary sum, and the arguments of each constructor are represented using an n-ary product.

This package provides a library and an executable for working with derived Show instances. By using the library, derived Show instances can be parsed into a generic data structure. The ppsh tool uses the library to produce human-readable versions of Show instances, which can be quite handy for debugging Haskell programs. We can also render complex generic values into an interactive Html page, for easier examination.

This package provides a writer monad for multi-line string literals.

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

This package provides a Dec type for representing deciable relations.

type Neg a = a -> Void

data Dec a
    = Yes a
    | No (Neg a)

This library provides Haskell bindings for checking currently mounted filesystems.

The mockery package provides support functions for automated testing.

This Haskell package provides a family of type-safe templates with simple variable interpolation. Shakespeare templates can be used inline with a quasi-quoter or in an external file and it interpolates variables according to the type being inserted.

Parsec is designed from scratch as an industrial-strength parser library. It is simple, safe, well documented (on the package homepage), has extensive libraries, good error messages, and is fast. It is defined as a monad transformer that can be stacked on arbitrary monads, and it is also parametric in the input stream type.

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.

This package provides modules containing facilities for manipulating Haskell source code using Template Haskell. See http://www.haskell.org/haskellwiki/Template_Haskell for more information.

This package contains a backend for ghc-persistent using the MySQL database server. Internally it uses the ghc-mysql-simple and mysql packages in order to access the database. This package supports only MySQL 5.1 and above. However, it has been tested only on MySQL 5.5. Only the InnoDB storage engine is officially supported.

This package provides testing utilities that are useful in conjunction with the Validity typeclass.

This package provides a library that performs fast, accurate conversion between double precision floating point and text.

This package provides a minimal host for SDL2-based Reflex applications.

Backported versions of types that were added to transformers in transformers 0.3 and 0.4 for users who need strict transformers 0.2 or 0.3 compatibility to run on old versions of the platform.

This library implements the GHC API. It is like the compiler-provided ghc package, but it can be loaded on many compiler versions.

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

Provides default instances for types from the dlist package.

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