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 Pure Haskell implementation of the SplitMix pseudorandom number generator. SplitMix is a "splittable" pseudorandom number generator that is quite fast: 9 64-bit arithmetic/logical operations per 64 bits generated. SplitMix is tested with two standard statistical test suites (DieHarder and TestU01, this implementation only using the former) and it appears to be adequate for "everyday" use, such as Monte Carlo algorithms and randomized data structures where speed is important. In particular, it should not be used for cryptographic or security applications, because generated sequences of pseudorandom values are too predictable (the mixing functions are easily inverted, and two successive outputs suffice to reconstruct the internal state).

Lua module wrapping Text.DocLayout.

The haskell-src package provides support for manipulating Haskell source code. The package provides a lexer, parser and pretty-printer, and a definition of a Haskell abstract syntax tree (AST). Common uses of this package are to parse or generate Haskell 98 code.

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

This package provides extra instances for type-classes in the [indexed-traversable](https://hackage.haskell.org/package/indexed-traversable) package. . The intention is to keep this package minimal; it provides instances that formerly existed in @lens@ or @optics-extra@. We recommend putting other instances directly into their defining packages. The @indexed-traversable@ package is light, having only GHC boot libraries as its dependencies.

This package provides a quasi-quoter for raw SQL for ghc-persistent.

This package provides access to platform dependent file locking APIs. There are alternative file locking packages:

• GHC.IO.Handle.Lock in base >= 4.10 is good enough for most use cases. However, uses only Handles so these locks cannot be used for intra-process locking.

• ghc-filelock doesn't support OFD locking.

Alternative parser for the Cassava package written with Megaparsec that provides for better error messages at the expense of some speed.

* @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)

The conduit package itself maintains relative small dependencies. The purpose of this package is to collect commonly used utility functions wrapping other library dependencies, without depending on heavier-weight dependencies. The basic idea is that this package should only depend on haskell-platform packages and conduit.

Happy is a parser generator for Haskell. Given a grammar specification in BNF, Happy generates Haskell code to parse the grammar. Happy works in a similar way to the yacc tool for C.

This Haskell library provides pointed and copointed data types.

Text.Regex.Base provides the interface API for regex-posix, regex-pcre, regex-parsec, regex-tdfa, regex-dfa.

This package provides a library implementing the XDG Base Directory spec.

This library provides functions for use in parsing indentation sensitive contexts. It parses blocks of lines all indented to the same level as well as lines continued at an indented level below.

This library provides the Data.Primitive.Addr module that was a part of the primitive library before primitive-0.7.0.0.

This Haskell package aims to be an RFC3986 compliant URI parser that uses ByteStrings for parsing and representing the URI data.

This library provides Comonads for Haskell.

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

Haddock is a documentation-generation tool for Haskell libraries.

This package provides Unix terminal support for Vty.

This library provides higher order versions of Prelude classes to ease programming with polymorphic recursion and reduce UndecidableInstances.
