An integration library for hspec and hedgehog.

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 package provides Haskell APIs to efficiently access the <https://www.unicode.org/ucd/ Unicode character database> (UCD). Performance is the primary goal in the design of this package. The Haskell data structures are generated programmatically from the UCD files.

This package provides testing utilities that are useful in conjunction with the Validity typeclass.

This package provides automatic formatting for Haskell files. Both a library and an executable.

This package provides Prism and Traversals for These.

This library provides tools for fast Unicode 12.1.0 normalization in Haskell (normalization forms C, KC, D, and KD).

This library provides a class for non-negative numbers, a wrapper which can turn any ordered numeric type into a member of that class, and a lazy number type for non-negative numbers (a generalization of Peano numbers).

This package tries to compat as many time features as possible.

* @Boring@ types are isomorphic to @()@. . * @Absurd@ types are isomorphic to @Void@. . See [What does () mean in Haskell -answer by Conor McBride](https://stackoverflow.com/questions/33112439/what-does-mean-in-haskell/33115522#33115522)

This is a modified version of wl-pprint, which was based on Wadler's paper "A Prettier Printer". This version allows the library user to annotate the text with semantic information, which can later be rendered in a variety of ways.

This package allows simple reflection of expressions containing variables. Reflection here means that a Haskell expression is turned into a string. The primary aim of this package is teaching and understanding; there are no options for manipulating the reflected expressions beyond showing them.

This library parses and dumps documents that are formatted according to RFC 4180, The common Format and MIME Type for Comma-Separated Values (CSV) Files. This format is used, among many other things, as a lingua franca for spreadsheets, and for certain web services.

This library provides a fast parser combinator library, aimed particularly at dealing efficiently with network protocols and complicated text/binary file formats.

Safe conversions between textual types

Haskell-Source with Extensions (HSE, haskell-src-exts) is an extension of the standard haskell-src package, and handles most registered syntactic extensions to Haskell. All extensions implemented in GHC are supported. Apart from these standard extensions, it also handles regular patterns as per the HaRP extension as well as HSX-style embedded XML syntax.

This package provides Haskell bindings to SDL2_image.

This library provides the natural numbers for Haskell.

This library provides an efficient implementation of Int-indexed arrays (both mutable and immutable), with a powerful loop optimisation framework.

Contravariant functors for Haskell.

This package provides an URI manipulation interface. In network-2.6 the Network.URI module was split off from the network package into this package.

Trifecta is a modern parser combinator library for Haskell, with slicing and Clang-style colored diagnostics.

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read and write Markdown and (subsets of) other formats, such as HTML, reStructuredText, LaTeX, DocBook, and many more.

Pandoc extends standard Markdown syntax with footnotes, embedded LaTeX, definition lists, tables, and other features. A compatibility mode is provided for those who need a drop-in replacement for Markdown.pl.

This is only for use in developing libraries that should conform to the persistent interface, not for users of the persistent suite of database libraries.
