This package provides functionality for manipulating @OsString@ values, and is shipped with <https://www.haskell.org/ghc/ GHC>.

This library provides a fast logging system for Haskell.

This package implements utilities to perform atomic output so as to avoid the problem of partial intermediate files.

This library provides exception safe semaphores that can be used in place of QSem, QSemN, and SampleVar, all of which are not exception safe and can be broken by killThread.

This package introduces a type for paths upholding useful invariants.

This package defines the type class MonadBaseControl, a subset of MonadBase into which generic control operations such as catch can be lifted from IO or any other base monad.

This package provides a Haskell type inhabited by finitely many values and indexed by type-level naturals.

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 uses a monad transformer approach for logging.

This package provides Template Haskell functions for determining source code locations of messages.

The major use of These of this is provided by the align member of Semialign class, representing a generalized notion of "zipping with padding" that combines structures without truncating to the size of the smaller input. It turns out that zip operation fits well the Semialign class, forming lattice-like structure.

SDL_mixer is a sample multi-channel audio mixer library. It supports any number of simultaneously playing channels of 16 bit stereo audio, plus a single channel of music, mixed by the popular MikMod MOD, Timidity MIDI, Ogg Vorbis, and SMPEG MP3 libraries.

This library provides data structures for describing changes to other data structures. In this library, a patch is something that can be applied, analogous to a function, and which distinguishes returning the argument it was provided from returning something else.

Various tasty helpers and utilities to test HsLua oparations. Built on top of tasty-hunit.

A priority search queue efficiently supports the operations of both a search tree and a priority queue. A Binding is a product of a key and a priority. Bindings can be inserted, deleted, modified and queried in logarithmic time, and the binding with the least priority can be retrieved in constant time. A queue can be built from a list of bindings, sorted by keys, in linear time.

This is an industrial-strength monadic parser combinator library. Megaparsec is a feature-rich package that strikes a nice balance between speed, flexibility, and quality of parse errors.

This package turn Data.Serialize Gets and Puts into Sources, Sinks, and Conduits.

This package provides a backend for the ghc-persistent library using the ghc-postgresql-simple package.

This library provides instances of Binary for the types defined in the vector package, making it easy to serialize vectors to and from disk. We use the generic interface to vectors, so all vector types are supported. Specific instances are provided for unboxed, boxed and storable vectors.

This package provides Unix terminal support for Vty.

This package provides Type-level booleans.

This package provides a pure Haskell client library for the Music Player Daemon.

This library provides file handling utilities for Haskell.

This package contains an implementation of a high-quality splittable pseudorandom number generator. The generator is based on a cryptographic hash function built on top of the ThreeFish block cipher. See the paper "Splittable Pseudorandom Number Generators Using Cryptographic Hashing" by Claessen, Pałka for details and the rationale of the design.

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