ANSI terminal backend for the prettyprinter package.

This package provides Haskell bindings to bibutils, a library that interconverts between various bibliography formats using a common MODS-format XML intermediate.

This library tries to call minimum system calls which are the bottleneck of web servers.

This Haskell library provides a type class for the error function, erf, and related functions. Instances for Float and Double.

This package provides utilities to inline C++ code into Haskell using inline-c.

A Haskell 98 logically uninhabited data type, used to indicate that a given term should not exist.

This Haskell package provides Monomorphic variants of the Functor, Foldable, and Traversable typeclasses. If you understand Haskell's basic typeclasses, you understand mono-traversable. In addition to what you are used to, it adds on an IsSequence typeclass and has code for marking data structures as non-empty.

A clone of wl-pprint for use with the text library.

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'.

This library provides exception safe semaphores that can be used in place of QSem, QSemN, and SampleVar, all of which are not exception safe and can be broken by killThread.

The major use of These of this is provided by the align member of Semialign class, representing a generalized notion of "zipping with padding" that combines structures without truncating to the size of the smaller input. It turns out that zip operation fits well the Semialign class, forming lattice-like structure.

This package provides a pandoc scripting engine based on Lua.

doclayout is a pretty-printing library for laying out text documents, with several features not present in pretty-printing libraries designed for code. It was designed for use in Pandoc.

Convenience functions and TH for working with constraints. See README.md for example usage.

This package defines orphan instances that mimic instances available in later versions of base to a wider (older) range of compilers.

This package provides default instances for types from the base package.

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

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

This package provides memory abstractions, such as chunk of memory, polymorphic byte array management and manipulation functions. It contains a polymorphic byte array abstraction and functions similar to strict ByteString, different type of byte array abstraction, raw memory IO operations (memory set, memory copy, ..) and more

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 defines the type class MonadBaseControl, a subset of MonadBase into which generic control operations such as catch can be lifted from IO or any other base monad.

This Haskell package provides three useful generalizations:

class Functor f => FunctorWithIndex i f | f -> i where
  imap :: (i -> a -> b) -> f a -> f b

class Foldable f => FoldableWithIndex i f | f -> i where
  ifoldMap :: Monoid m => (i -> a -> m) -> f a -> m

class (FunctorWithIndex i t, FoldableWithIndex i t, Traversable t)
       => TraversableWithIndex i t | t -> i where
  itraverse :: Applicative f => (i -> a -> f b) -> t a -> f (t b)

The ghc-keys package provides similar functionality, but uses associated TypeFamilies instead of FunctionalDependencies.

This package provides a library for generating 2D charts and plots, with backends provided by the Cairo and Diagrams libraries.

Cross platform library for file creation, modification, and deletion notification. This library builds upon existing libraries for platform specific Windows, Mac, and Linux file system event notification.
