This Haskell package was originally present in classy-prelude.

Types that are parametric on a functor are like Barbies that have an outfit for each role. This package provides the basic abstractions to work with them comfortably.

GLURaw is a raw Haskell binding for the GLU 1.3 OpenGL utility library. It is basically a 1:1 mapping of GLU's C API, intended as a basis for a nicer interface.

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.

This package defines a class for types with a default value, and provides instances for types from the base, containers, dlist and old-locale packages.

This library provides convenient combinators for working with and building parsing combinator libraries. Given a few simple instances, you get access to a large number of canned definitions. Instances exist for the parsers provided by parsec, attoparsec and base's Text.Read.

Expose Haskell objects to Lua with an object oriented interface.

Async provides a library to run IO operations asynchronously, and wait for their results. It is a higher-level interface over threads in Haskell, in which Async a is a concurrent thread that will eventually deliver a value of type a.

This library provides Mustache templates for Haskell based on the stache library using parsec instead of megaparsec.

This package introduces a type for paths upholding useful invariants.

This package includes Hakell modules providing various helper functions for Lists, Maybes, Tuples, Functions.

This library provides a wide array of (semi)groupoids and operations for working with them. A Semigroupoid is a Category without the requirement of identity arrows for every object in the category. A Category is any Semigroupoid for which the Yoneda lemma holds. Finally, to work with these weaker structures it is beneficial to have containers that can provide stronger guarantees about their contents, so versions of Traversable and Foldable that can be folded with just a Semigroup are added.

This package provides bindings and types to bridge Haskell and <https://www.lua.org/ Lua>. . The full Lua interpreter version 5.4.4 is included. Alternatively, a system-wide Lua installation can be linked instead.

Provides instances of the Validity type class for lazy and strict ByteStrings and ShortByteStrings.

An implementation of the git-lfs protocol.

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 provides Haskell bindings to SDL2_mixer.

This package provides a collection of Haskell functions for splitting lists into parts, akin to the split function found in several mainstream languages.

This library provides profunctors for Haskell.

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

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 utilities and combinators for parsing command line options in Haskell.

This package provides a simple XML library for Haskell.

This package provides bindings to libpq: the C application programmer's interface to PostgreSQL. libpq is a set of library functions that allow client programs to pass queries to the PostgreSQL backend server and to receive the results of these queries.
