Uniplate is a library for writing simple and concise generic operations. Uniplate has similar goals to the original Scrap Your Boilerplate work, but is substantially simpler and faster.

This is a Haskell library to derive Template Haskell's Lift class for datatypes.

The ghc-ini Haskell library lets programmers quickly and easily read and write configuration files in the simple INI format.

This package provides a Haskell library including a couple of different implementations of mutable hash tables in the ST monad, as well as a typeclass abstracting their common operations, and a set of wrappers to use the hash tables in the IO monad.

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

This package provides IO operations from async package lifted to any instance of MonadBase or MonadBaseControl.

SDL_image is an image file loading library. It loads images as SDL surfaces, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, XCF, XPM, XV.

This library provides a YAML 1.2 parser implementation for Haskell. Its features include:

• Pure Haskell implementation with small dependency footprint and emphasis on strict compliance with the YAML 1.2 specification.

• Direct decoding to native Haskell types via (aeson-inspired) typeclass-based API (see Data.YAML).

• Support for constructing custom YAML node graph representation (including support for cyclic YAML data structures).

• Support for the standard (untyped) Failsafe, (strict) JSON, and (flexible) Core ``schemas'' providing implicit typing rules as defined in the YAML 1.2 specification (including support for user-defined custom schemas).

• Event-based API resembling LibYAML's Event-based API (see Data.YAML.Event).

• Low-level API access to lexical token-based scanner (see Data.YAML.Token).

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.

This package provides a variety of alternative parser combinator libraries, including the original HuttonMeijer set. The Poly sets have features like good error reporting, arbitrary token type, running state, lazy parsing, and so on. Finally, Text.Parse is a proposed replacement for the standard Read class, for better deserialisation of Haskell values from Strings.

This library provides fast parsing and formatting utilities for Unix time in Haskell.

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 Haskell library provides a Template Haskell deriver for unboxed vectors, given a pair of coercion functions to and from some existing type with an Unbox instance.

This library provides functions for control flow inside of monads with anaphoric variants on if and when and a C-like switch function.

This Haskell package aims to be an RFC3986 compliant URI parser that uses ByteStrings for parsing and representing the URI data.

This Haskell package provides compatibility layer for ghc-aeson.

This Haskell library provides a simple purely functional circular list, or ring, data type: a circular data structure such that if you continue rotating the ring in either direction, you'll eventually return to the element you first observed.

This library provides the POSIX regex backend used by the Haskell library regex-base.

SmallCheck is a testing library that verifies properties for all test cases up to some depth. The test cases are generated automatically by SmallCheck.

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 basic random number generation library, including the ability to split random number generators.

Zstandard compression packaged as a conduit. This is a very thin wrapper around the official hs-zstd interface.

Atomically write to a file on POSIX-compliant systems while preserving permissions. mv is an atomic operation. This makes it simple to write to a file atomically just by using the mv operation. However, this will destroy the permissions on the original file. This library preserves permissions while atomically writing to a file.
