Special values are provided by a SpecialValues typeclass. Those can be used for example by QuickCheck, see quickcheck-special.

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.

This tiny package contains the class ObjectName, which corresponds to the general notion of explicitly handled identifiers for API objects, e.g. a texture object name in OpenGL or a buffer object name in OpenAL.

Skylighting is a syntax highlighting library with support for over one hundred languages. It derives its tokenizers from XML syntax definitions used by KDE's KSyntaxHighlighting framework, so any syntax supported by that framework can be added. An optional command-line program is provided. Skylighting is intended to be the successor to highlighting-kate. This package provides generated syntax modules based on the KDE XML definitions provided by the skylighting-core package.

This library provides a pure Haskell implementation of the Unicode Collation Algorithm described at http://www.unicode.org/reports/tr10/. It is not as fully-featured or as performant as text-icu, but it avoids a dependency on a large C library. Locale-specific tailorings are also provided.

Knowledge of GHC's installation directories.

inline-c lets you seamlessly call C libraries and embed high-performance inline C code in Haskell modules. Haskell and C can be freely intermixed in the same source file, and data passed to and from code in either language with minimal overhead. No FFI required.

A rich drop-in replacement for base. For details and documentation please visit the project's home page.

This package provides datatypes to construct Free monads, Free monad transformers, and useful instances. In addition it provides the constructs to avoid quadratic complexity of left associative bind, as explained in:

• Janis Voigtlander, Asymptotic Improvement of Computations over Free Monads, MPC'08

This package provides Haskell modules to allow use of Accessor to access state in transformers State monad.

The word-wrap Haskell library wraps long lines of text.

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

This Hackage security library provides both server and client utilities for securing the Hackage package server. It is based on The Update Framework, a set of recommendations developed by security researchers at various universities in the US as well as developers on the Tor project.

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.

Old-time is a package for backwards compatibility with the old time library. For new projects, the newer time library is recommended.

This package provides functionality for manipulating @OsString@ values, and is shipped with <https://www.haskell.org/ghc/ GHC>.

Pandoc-cli provides a command-line executable that uses the pandoc library to convert between markup formats.

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 library provides functions available in later versions of base to a wider range of compilers, without requiring the use of CPP pragmas in your code.

Transformers provides functor and monad transformers, inspired by the paper "Functional Programming with Overloading and Higher-Order Polymorphism", by Mark P Jones, in Advanced School of Functional Programming, 1995 http://web.cecs.pdx.edu/~mpj/pubs/springschool.html.

This package contains:

• the monad transformer class (in Control.Monad.Trans.Class)

• concrete functor and monad transformers, each with associated operations and functions to lift operations associated with other transformers.

This package can be used on its own in portable Haskell code, in which case operations need to be manually lifted through transformer stacks (see Control.Monad.Trans.Class for some examples). Alternatively, it can be used with the non-portable monad classes in the mtl or monads-tf packages, which automatically lift operations introduced by monad transformers through other transformers.

Provides default instances for types from the containers package.

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 library provides an interface to GSL special functions for Haskell.

This library provides tools for ensuring that class members are shared.
