This package provides a quasi-quoter for raw SQL for ghc-persistent.

This library is simply a collection of linear-algebra related modules split from the statistics library.

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

This package provides a monad transformer version of the ST monad for strict state threads.

This package provides Data.Scientific, which provides the number type Scientific. Scientific numbers are arbitrary precision and space efficient. They are represented using scientific notation.

Alternative parser for the Cassava package written with Megaparsec that provides for better error messages at the expense of some speed.

An integration library for hspec and hedgehog.

This package provides vaults for Haskell. A vault is a persistent store for values of arbitrary types. It's like having first-class access to the storage space behind IORefs. The data structure is analogous to a bank vault, where you can access different bank boxes with different keys; hence the name. Also provided is a locker type, representing a store for a single element.

Experimental Hspec support for testing WAI applications

This library provides core modules of a markup combinator library for Haskell.

Highlighting-kate is a syntax highlighting library with support for nearly one hundred languages. The syntax parsers are automatically generated from Kate syntax descriptions, so any syntax supported by Kate can be added. An (optional) command-line program is provided, along with a utility for generating new parsers from Kate XML syntax descriptions.

This package provides an implementation of the standard diff algorithm, and utilities for pretty printing.

This library provides a type for specifying Optional function arguments.

This Haskell package provides striped pooling abstraction for managing flexibly-sized collections of resources such as database connections.

Bindings to the Xft, X Free Type interface library, and some Xrender parts.

This package introduces a type for paths upholding useful invariants.

This package provides a Dec type for representing deciable relations.

type Neg a = a -> Void

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

This Hackage security library provides both server and client utilities for securing the Hackage package server. It is based on The Update Framework, a set of recommendations developed by security researchers at various universities in the US as well as developers on the Tor project.

Skylighting is a syntax highlighting library with support for over one hundred languages. It derives its tokenizers from XML syntax definitions used by KDE's KSyntaxHighlighting framework, so any syntax supported by that framework can be added. An optional command-line program is provided. Skylighting is intended to be the successor to highlighting-kate. This package provides generated syntax modules based on the KDE XML definitions provided by the skylighting-core package.

This package provides a Pure Haskell implementation of the SplitMix pseudorandom number generator. SplitMix is a "splittable" pseudorandom number generator that is quite fast: 9 64-bit arithmetic/logical operations per 64 bits generated. SplitMix is tested with two standard statistical test suites (DieHarder and TestU01, this implementation only using the former) and it appears to be adequate for "everyday" use, such as Monte Carlo algorithms and randomized data structures where speed is important. In particular, it should not be used for cryptographic or security applications, because generated sequences of pseudorandom values are too predictable (the mixing functions are easily inverted, and two successive outputs suffice to reconstruct the internal state).

This library provides extra functions for the standard Haskell libraries. Most functions are simple additions, filling out missing functionality. A few functions are available in later versions of GHC, but this package makes them available back to GHC 7.2.

This package provides orphan instances for Template Haskell datatypes. In particular, instances for Ord and Lift, as well as a few missing Show and Eq instances. These instances used to live in the haskell-src-meta package, and that's where the version number started.

Provides an efficient Haskell implementation of Peano numbers

The functions for creating temporary files and directories in the base library are quite limited. The unixutils package contains some good ones, but they aren't portable to Windows. This library just repackages the Cabal implementations of its own temporary file and folder functions so that you can use them without linking against Cabal or depending on it being installed. This is a better maintained fork of the "temporary" package.
