The ListLike module provides a common interface to the various Haskell types that are list-like. Predefined interfaces include standard Haskell lists, Arrays, ByteStrings, and lazy ByteStrings. Custom types can easily be made ListLike instances as well.

ListLike also provides for String-like types, such as String and ByteString, for types that support input and output, and for types that can handle infinite lists.

This library provides tools to calculate various string metrics efficiently.

Provides a FilePath datatype and utility functions for operating on it. Unlike the filepath package, this package does not simply reuse String, increasing type safety.

Haskell bindings to the International Components for Unicode (ICU) libraries. These libraries provide robust and full-featured Unicode services on a wide variety of platforms. . Features include: . * Both pure and impure bindings, to allow for fine control over efficiency and ease of use. . * Breaking of strings on character, word, sentence, and line boundaries. . * Access to the Unicode Character Database (UCD) of character metadata. . * String collation functions, for locales where the conventions for lexicographic ordering differ from the simple numeric ordering of character codes. . * Character set conversion functions, allowing conversion between Unicode and over 220 character encodings. . * Unicode normalization. (When implementations keep strings in a normalized form, they can be assured that equivalent strings have a unique binary representation.) . * Regular expression search and replace. . * Security checks for visually confusable (spoofable) strings. . * Bidirectional Unicode algorithm . * Calendar objects holding dates and times. . * Number and calendar formatting.

This package provides a pure interface for compressing and decompressing LZMA streams of data represented as lazy ByteStrings. A monadic incremental interface is provided as well.

This library provides a fast logging system for Haskell.

Clear to write, read and edit Haskell DSL for HTML.

• Names are consistent, and do not conflict with base or are keywords (all have suffix -).

• Same combinator can be used for attributes and elements (e.g. style_).

Type classes for convenient marshalling and calling of Lua functions.

This library provides implementations of concurrent FIFO queues (for both general boxed and primitive unboxed values) that are fast, perform well under contention, and offer a Chan-like interface. The library may be of limited usefulness outside of x86 architectures where the fetch-and-add instruction is not available.

This library provides fast parsing and formatting utilities for Unix time in Haskell.

This package provides Haskell bindings to the setlocale C function.

Manipulate identifiers and structurally non-complex pieces of text by delimiting word boundaries via a combination of whitespace, control-characters, and case-sensitivity.

Has support for common idioms like casing of programmatic variable names, taking, dropping, and splitting by word, and modifying the first character of a piece of text.

Caution: this library makes heavy use of the text library's internal loop optimisation framework. Since internal modules are not guaranteed to have a stable API there is potential for build breakage when the text dependency is upgraded. Consider yourself warned!

Safe Haskell introduced the notion of safe and unsafe modules. In order to make as many as possible modules ``safe'', the well-known unsafe functions were moved to distinguished modules. This makes it hard to write packages that work with both old and new versions of GHC. This package provides a single module System.Unsafe that exports the unsafe functions from the base package. It provides them in a style ready for qualification, that is, you should import them by import qualified System.Unsafe as Unsafe.

This package provides a collection of Haskell functions for splitting lists into parts, akin to the split function found in several mainstream languages.

Most data types in the Haskell platform do not have Lift instances. This package provides orphan instances for containers, text, bytestring and vector.

This library provides core modules of a markup combinator library for Haskell.

This library provides a conduit-based, streaming interface for extracting and creating tar files.

This package provides a compatibility layer for using GHC call stacks with different versions of the compiler.

This is a set of macros to be used when writing Haskell FFI. They were designed to be able to fully describe C interfaces, so that hsc2hs can extract from them all Haskell code needed to mimic such interfaces. All Haskell names used are automatically derived from C names, structures are mapped to Haskell instances of Storable, and there are also macros you can use with C code to help write bindings to inline functions or macro functions.

Types that are parametric on a functor are like Barbies that have an outfit for each role. This package provides the basic abstractions to work with them comfortably.

This package provides a GHC.Generics-based Control.DeepSeq.Generics.genericRnf function which can be used for providing an rnf implementation.

The texmath library provides functions to read and write TeX math, presentation MathML, and OMML (Office Math Markup Language, used in Microsoft Office). Support is also included for converting math formats to pandoc's native format (allowing conversion, via pandoc, to a variety of different markup formats). The TeX reader supports basic LaTeX and AMS extensions, and it can parse and apply LaTeX macros.

Checkers wraps up the expected properties associated with various standard type classes as QuickCheck properties. It also provides some morphism properties, arbitrary instances, and generator combinators for common data types.

The functions for creating temporary files and directories in the base library are quite limited. The unixutils package contains some good ones, but they aren't portable to Windows. This library just repackages the Cabal implementations of its own temporary file and folder functions so that you can use them without linking against Cabal or depending on it being installed. This is a better maintained fork of the "temporary" package.
