This package provides a Storable instance for pairs and triples which should be binary compatible with C99 and C++. The only purpose of this package is to provide a standard location for this instance so that other packages needing this instance can play nicely together.

The Par monad offers an API for parallel programming. The library works for parallelising both pure and IO computations, although only the pure version is deterministic. The default implementation provides a work-stealing scheduler and supports forking tasks that are much lighter weight than IO-threads.

This package provides Unix terminal support for Vty.

This package provides a library that performs fast, accurate conversion between double precision floating point and text.

This library provides bindings for the Dot language used by the Graphviz suite of programs for visualising graphs, as well as functions to call those programs. Main features of the graphviz library include:

1. Almost complete coverage of all Graphviz attributes and syntax

2. Support for specifying clusters

3. The ability to use a custom node type

4. Functions for running a Graphviz layout tool with all specified output types

5. Generate and parse Dot code with two options: strict and liberal

6. Functions to convert FGL graphs and other graph-like data structures

7. Round-trip support for passing an FGL graph through Graphviz to augment node and edge labels with positional information, etc.

Expose Haskell objects to Lua with an object oriented interface.

This package exports a module which is the recommended starting point for using microlens if you aren't trying to keep your dependencies minimal. By importing Lens.Micro.Platform you get all functions and instances from microlens, microlens-th, microlens-mtl, microlens-ghc, as well as instances for Vector, Text, and HashMap. The minor and major versions of microlens-platform are incremented whenever the minor and major versions of any other microlens package are incremented, so you can depend on the exact version of microlens-platform without specifying the version of microlens you need. This package is a part of the microlens family; see the readme on Github.

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.

A parser and renderer for binary Olson timezone files whose format is specified by the tzfile(5) man page on Unix-like systems. For more information about this format, see http://www.iana.org/time-zones/repository/tz-link.html. Functions are provided for converting the parsed data into TimeZoneSeries objects from the timezone-series package.

This package implements the bijection between JSON and CBOR defined in the CBOR specification, RFC 7049.

This package provides a pretty printing class similar to Show, based on the HughesPJ pretty printing library. It provides the pretty printing class and instances for the Prelude types.

This Haskell package provides a family of type-safe templates with simple variable interpolation. Shakespeare templates can be used inline with a quasi-quoter or in an external file and it interpolates variables according to the type being inserted.

This package provides portable implementations of parts of the unix package. This package re-exports the unix package when available. When it isn't available, portable implementations are used.

The PGP Word List consists of two phonetic alphabets, each with one word per possible byte value. A string of bytes is translated with these alphabets, alternating between them at each byte.

The PGP words corresponding to the bytes 5B 1D CA 6E are "erase breakaway spellbind headwaters", for example.

For further information, see http://en.wikipedia.org/wiki/PGP_word_list.

This library provides peek and poke functions for network byte order.

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

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.

Simple DirectMedia Layer (libSDL) is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. It is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."

This package contains the generics system described in the /Scrap Your Boilerplate/ papers (see the website). It defines the Data class of types permitting folding and unfolding of constructor applications, instances of this class for primitive types, and a variety of traversals.

This package provides datatypes to construct Free monads, Free monad transformers, and useful instances. In addition it provides the constructs to avoid quadratic complexity of left associative bind, as explained in:

• Janis Voigtlander, Asymptotic Improvement of Computations over Free Monads, MPC'08

A cross-platform library for retrieving information about disk space usage.

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

This package allows you to use Template Haskell to read a file or all the files in a directory, and turn them into (path, bytestring) pairs embedded in your Haskell code.

This package provides helper functions for working with haskell-src-exts trees.
