GHC 7.4 gave us the ability to talk about ConstraintKinds. They stopped crashing the compiler in GHC 7.6. This package provides a vocabulary for working with them.

This module allows tokens produced by skylighting-core to be rendered as ConTeXt commands.

Set- and Map-like types that remember the order elements were inserted

This package provides access to ALSA infrastructure, that is needed by both alsa-seq and alsa-pcm.

This Haskell package provides some useful control operators for looping.

This package provides a newtype wrapper with FromJSON/ToJSON instances customisable via a phantom type parameter. The instances can be rendered to the original type using DerivingVia.

This library implements a technique to catch all exceptions raised within an enclosed computation, while remaining responsive to (external) asynchronous exceptions.

This package contains functions (like view or +=) which work on MonadReader, MonadWriter, and MonadState from the mtl package. This package is a part of the microlens family; see the readme on Github.

Text styling for ANSI terminals using SGR codes, as defined by the <https://www.ecma-international.org/publications-and-standards/standards/ecma-48 ECMA-48> standard. . Supports foreground\/background color, bold\/faint intensity, italic, single\/double underline, strikethrough, frame, encircle, and overline escape sequences. Some styles may not work on your terminal. . Also features terminal detection, so redirecting styled output to a file will automatically strip the ANSI escape sequences.

This package is an enhancement of the Text.Regex library. It wraps the PCRE C library providing Perl-compatible regular expressions.

This package contains basic primitives for the Foundation set of packages.

Haddock is a documentation-generation tool for Haskell libraries.

Word8 library to be used with Data.ByteString.

This library provides Haskell bindings to the Zstandard compression algorithm, a fast lossless compression algorithm targeting real-time compression scenarios at zlib-level and better compression ratios.

This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible. This package is the shared internal logic of the generic-lens and generic-optics libraries.

This package provides an abstract class to manipulate sequence of bytes. The use case of this class is abstracting manipulation of types that are just wrapping a bytestring with stronger and more meaniful name.

This package provides low-dependency functionality commonly needed by various Haskell streaming data libraries, such as conduit and pipes.

This package provides the following modules: Math.NumberTheory.Logarithms and Math.NumberTheory.Powers.Integer from the arithmoi package, GHC.Integer.Logarithms.Compat and Math.NumberTheory.Power.Natural, as well as some additional functions in migrated modules.

This package provides a binary serialization library, similar to binary, that introduces an isolate primitive for parser isolation, and labeled blocks for better error messages.

This package provides vaults for Haskell. A vault is a persistent store for values of arbitrary types. It's like having first-class access to the storage space behind IORefs. The data structure is analogous to a bank vault, where you can access different bank boxes with different keys; hence the name. Also provided is a locker type, representing a store for a single element.

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 package provides a parser for plain-text representations of tables. This package supports table headers, cells spanning multiple columns or rows, as well as a way to specify column alignments.

This library lets you derive automatically Haskell functions that let you query each endpoint of a <http://hackage.haskell.org/package/servant servant> webservice. . See <http://docs.servant.dev/en/stable/tutorial/Client.html the client section of the tutorial>. . <https://github.com/haskell-servant/servant/blob/master/servant-client/CHANGELOG.md CHANGELOG>.
