This library provides a continuation-based, backtracking, logic programming monad. An adaptation of the two-continuation implementation found in the paper "Backtracking, Interleaving, and Terminating Monad Transformers" available online.

Word8 library to be used with Data.ByteString.

This tiny package contains the class ObjectName, which corresponds to the general notion of explicitly handled identifiers for API objects, e.g. a texture object name in OpenGL or a buffer object name in OpenAL.

Cheapskate is an experimental Markdown processor in pure Haskell. It aims to process Markdown efficiently and in the most forgiving possible way. It is designed to deal with any input, including garbage, with linear performance. Output is sanitized by default for protection against cross-site scripting (XSS) attacks.

This package provides Haskell modules to allow use of Accessor to access state in transformers State monad.

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

This module allows tokens produced by skylighting-core to be rendered as ANSI colored text.

This library provides functions for parsing and pretty printing Roman numerals. Because the notation of Roman numerals has varied through the centuries this package allows for some customisation using a configuration that is passed to the conversion functions.

This package provides a pure interface for compressing and decompressing LZMA streams of data represented as lazy ByteStrings. A monadic incremental interface is provided as well.

This library provides fast base64 encoding and decoding for Haskell ByteStrings.

This package provides filtrable containers.

Type classes for convenient marshalling and calling of Lua functions.

This package contains a MonadRef type class that abstracts over the details of manipulating references, allowing one to write code that can operate in either the ST monad or the IO monad.

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).

Cairo is a library to render high quality vector graphics. There exist various backends that allows rendering to Gtk windows, PDF, PS, PNG and SVG documents, amongst others.

This library provides finger trees, a general sequence representation with arbitrary annotations, for use as a base for implementations of various collection types. It includes examples, as described in section 4 of Ralf Hinze and Ross Paterson, "Finger trees: a simple general-purpose data structure".

This Haskell library contains type definitions for Universally Unique Identifiers or UUIDs, and basic conversion functions.

This package provides a low-level networking interface.

LeanCheck is a simple enumerative property-based testing library. Properties are defined as Haskell functions returning a boolean value which should be true for all possible choices of argument values. LeanCheck applies enumerated argument values to these properties in search for a counterexample. Properties can be viewed as parameterized unit tests. LeanCheck works by producing tiers of test values: a possibly infinite list of finite sublists of same-and-increasingly-sized values.

A nonce is an arbitrary number used only once in a cryptographic communication. This package contain helper functions for generating nonces. There are many kinds of nonces used in different situations. It's not guaranteed that by using the nonces from this package you won't have any security issues. Please make sure that the nonces generated via this package are usable on your design.

This package provides Haskell bindings to the the POSIX network database (<netdb.h>) API.

This library defines a propositional equality data type, shims Data.Type.Equality as well as possible for older GHC versions (< 7.8).

data a :~: b where
  Refl :: a :~: a

The module Data.Type.Equality.Hetero shims @code:~~: equality, and for compilers with PolyKinds.

Automatically discover and run Hspec tests . <http://hspec.github.io/hspec-discover.html>

This package provides a set of helper programs necessary to build the Gtk2Hs suite of libraries. These tools include a modified c2hs binding tool that is used to generate FFI declarations, a tool to build a type hierarchy that mirrors the C type hierarchy of GObjects found in glib, and a generator for signal declarations that are used to call back from C to Haskell. These tools are not needed to actually run Gtk2Hs programs.
