This package provides two simple conduit wrappers around STM channels: a source and a sink.

This package provides a type-safe tool for generating XML code via quasi-quoting built on top of ghc-shakespeare.

This Haskell package lets you automatically generate lenses for data types; code was extracted from the lens package, and therefore generated lenses are fully compatible with ones generated by lens (and can be used both from lens and microlens).

Provides an efficient Haskell implementation of Peano numbers

Safe Haskell introduced the notion of safe and unsafe modules. In order to make as many as possible modules ``safe'', the well-known unsafe functions were moved to distinguished modules. This makes it hard to write packages that work with both old and new versions of GHC. This package provides a single module System.Unsafe that exports the unsafe functions from the base package. It provides them in a style ready for qualification, that is, you should import them by import qualified System.Unsafe as Unsafe.

This package provides a library for parallel programming.

This Haskell library provides implementations of special mathematical functions and Chebyshev polynomials. These functions are often useful in statistical and numerical computing.

This package provides functions for signed 15.16 precision fixed point arithmetic.

This package provides a family of combinators for defining webservices APIs and serving them . You can learn about the basics in the <http://docs.servant.dev/en/stable/tutorial/index.html tutorial>. . <https://github.com/haskell-servant/servant/blob/master/servant/CHANGELOG.md CHANGELOG>

This package provides pure-Haskell utilities for dealing with XML with the conduit package.

This package provides type classes, a monad and a monad transformer that support unchecked extensible exceptions as well as asynchronous exceptions. It is compatible with the transformers package.

This is a lightweight package providing commonly useful parser combinators.

This library contains simple and easy-to-use primitives for I/O using streams.

Derive instances of Arbitrary for QuickCheck, with various options to customize implementations.

Automating the arbitrary boilerplate also ensures that when a type changes to have more or fewer constructors, then the generator either fixes itself to generate that new case (when using the uniform distribution) or causes a compilation error so you remember to fix it (when using an explicit distribution).

This package also offers a simple (optional) strategy to ensure termination for recursive types: make Test.QuickCheck.Gen's size parameter decrease at every recursive call; when it reaches zero, sample directly from a trivially terminating generator given explicitly (genericArbitraryRec and withBaseCase) or implicitly (genericArbitrary').

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

This package provides functions to marshal and unmarshal pandoc document types to and from Lua. . The values of most types are pushed to pandoc as "userdata" objects that wrap a stable pointer to the Haskell value; these objects come with methods to access and modify their properties. . Sequences are pushed as normal Lua tables, but are augmented with convenience functions.

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

This Haskell package provides interfaces and helper functions for the ghc-persistent package.

This Haskell package offers a collection of channel types, similar to Control.Concurrent.STM.{TChan,TQueue} but with additional features.

Haskell bindings to the International Components for Unicode (ICU) libraries. These libraries provide robust and full-featured Unicode services on a wide variety of platforms. . Features include: . * Both pure and impure bindings, to allow for fine control over efficiency and ease of use. . * Breaking of strings on character, word, sentence, and line boundaries. . * Access to the Unicode Character Database (UCD) of character metadata. . * String collation functions, for locales where the conventions for lexicographic ordering differ from the simple numeric ordering of character codes. . * Character set conversion functions, allowing conversion between Unicode and over 220 character encodings. . * Unicode normalization. (When implementations keep strings in a normalized form, they can be assured that equivalent strings have a unique binary representation.) . * Regular expression search and replace. . * Security checks for visually confusable (spoofable) strings. . * Bidirectional Unicode algorithm . * Calendar objects holding dates and times. . * Number and calendar formatting.

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

Containers with merging via monoidal accumulation. The Monoid instances provided by the containers and unordered-containers packages merge structures in a left-biased manner instead of using the underlying monoidal structure of the value. This package wraps the types provided by these packages, but provides Monoid instances implemented in terms of the value type's mappend'.
