The ghc-lib-parser-ex package contains GHC API parse tree utilities.

This is a pretty printing library based on Wadler's paper "A Prettier Printer". It has been enhanced with support for ANSI terminal colored output using the ansi-terminal package.

This package is an enhancement of the Text.Regex library, providing the PCRE backend to accompany regex-base, with bundled code from https://www.pcre.org.

This package allows simple reflection of expressions containing variables. Reflection here means that a Haskell expression is turned into a string. The primary aim of this package is teaching and understanding; there are no options for manipulating the reflected expressions beyond showing them.

__This package is deprecated__. Please, use genByteString from the [random package (version >=1.2)](https://hackage.haskell.org/package/random) instead. . Efficient generation of random bytestrings. The implementation populates uninitialized memory with uniformily distributed random 64 bit words (and 8 bit words for remaining bytes at the end of the bytestring). . Random words are generated using the PRNG from the [mwc-random](https://hackage.haskell.org/package/mwc-random) package or the [pcg-random](https://hackage.haskell.org/package/pcg-random) package. It is also possible to use a custom PRNG by providing an instance for the RandomWords type class and using the function generate from the module "Data.ByteString.Random.Internal". . The generated byte strings are suitable for statistical applications. They are /not/ suitable for cryptographic applications. .  . 

Chell is a simple and intuitive library for automated testing. It natively supports assertion-based testing, and can use companion libraries such as chell-quickcheck to support more complex testing strategies.

This package provides an abstraction for communicating with line-oriented network services while abstracting over the use of SOCKS5 and TLS (via OpenSSL)

Experimental Hspec support for testing WAI applications

PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. Unlike many general-purpose RNGs, they are also hard to predict. . This library implements bindings to the standard C implementation. This includes the standard, unique, fast and single variants in the pcg family. There is a pure implementation that can be used as a generator with the random package as well as a faster primitive api that includes functions for generating common types. . The generators in this module are suitable for use in parallel but make sure threads don't share the same generator or things will go horribly wrong.

This package provides a UTF-8 aware subset of Lua's string module for Haskell. The functions provided by this module are upper, lower, len, reverse, and sub.

This Haskell library algorithms for vector arrays.

wordexp(3) wrapper library for Haskell to perform word expansion like a posix-shell.

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.

Safe Haskell introduced the notion of safe and unsafe modules. In order to make as many as possible modules ``safe'', the well-known unsafe functions were moved to distinguished modules. This makes it hard to write packages that work with both old and new versions of GHC. This package provides a single module System.Unsafe that exports the unsafe functions from the base package. It provides them in a style ready for qualification, that is, you should import them by import qualified System.Unsafe as Unsafe.

This package provides a parser and pretty printer for converting between Haskell values and JSON. JavaScript Object Notation is a lightweight data-interchange format.

This is library provides utility to use Netlink from Haskell. The scope of this package extends over general Netlink support to specific implementations of Netlink families.

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 a simple logging abstraction that allows multiple back-ends.

Wrapper for the Data.Version.Version Haskell type.

This library provides file handling utilities for Haskell.

A rich drop-in replacement for base. For details and documentation please visit the project's home page.

This package provides a Dec type for representing deciable relations.

type Neg a = a -> Void

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

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 Haskell package provides additional data structures, and other added capabilities layered on top of the Par monad.
