This package provides an implementation of the standard diff algorithm, and utilities for pretty printing.

ResourceT is a monad transformer which creates a region of code where you can safely allocate resources.

RFC 4648-compliant Base64 with an eye towards performance and modernity (additional support for RFC 7049 standards)

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 various extra monoid-related definitions and utilities, such as monoid actions, monoid coproducts, semi-direct products, "deletable" monoids, "split" monoids, and "cut" monoids.

This library provides a type-safe embedded domain specific language (EDSL) for SQL queries that works with SQL backends as provided by ghc-persistent. Its language closely resembles SQL, so you don't have to learn new concepts, just new syntax, and it's fairly easy to predict the generated SQL and optimize it for your backend.

Pattern synonyms for ASCII characters, e.g. . @ pattern SPACE :: Word8 pattern SPACE = 0x20 @.

The ghc-lib-parser-ex package contains GHC API parse tree utilities.

Concatenative gives Haskell Factor-style combinators and arrows for postfix notation. For more information on stack based languages, see https://concatenative.org.

ghc-citeproc parses Citation Style Language style files and uses them to generate a list of formatted citations and bibliography entries. For more information about CSL, see https://citationstyles.org/.

PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. Unlike many general-purpose RNGs, they are also hard to predict. . This library implements bindings to the standard C implementation. This includes the standard, unique, fast and single variants in the pcg family. There is a pure implementation that can be used as a generator with the random package as well as a faster primitive api that includes functions for generating common types. . The generators in this module are suitable for use in parallel but make sure threads don't share the same generator or things will go horribly wrong.

This package is an enhancement of the Text.Regex library, providing the PCRE backend to accompany regex-base, with bundled code from https://www.pcre.org.

This library provides extensible optionally-pure exceptions for Haskell.

This library provides functions to read, write and manipulate MIDI, WAVE and SoundFont2 multimedia files. It is written entirely in Haskell (without any FFI). It uses efficient parsing and building combinators for binary data stored in ByteStrings (based on the one in binary package).

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

This package provides modules containing facilities for manipulating Haskell source code using Template Haskell. See http://www.haskell.org/haskellwiki/Template_Haskell for more information.

This library provides monad morphism utilities, most commonly used for manipulating monad transformer stacks.

This Haskell library provides a Template Haskell deriver for unboxed vectors, given a pair of coercion functions to and from some existing type with an Unbox instance.

This package provides a backwards compatibility layer for Template Haskell newer than 2.8.

This package provides a full-featured binding to the C libmagic library. With it, you can determine the type of a file by examining its contents rather than its name.

This package defines new symbols for a number of functions, operators and types in the base package. All symbols are documented with their actual definition and information regarding their Unicode code point. They should be completely interchangeable with their definitions. For further Unicode goodness you can enable the UnicodeSyntax language extension. This extension enables Unicode characters to be used to stand for certain ASCII character sequences, i.e. → instead of ->, ∀ instead of forall and many others.

This is a compatibility package as @Generically@ and @Generically1@ newtypes are available since @base-4.17@ in GHC.Generics'.

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

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.
