This package provides a fully compliant Haskell 98 lexer.

The options package lets library and application developers easily work with command-line options.

This package provides the Network.Multicast Haskell module for sending UDP datagrams over multicast (class D) addresses.

This library provides file handling utilities for Haskell.

This library lets you create a one-shot timer, poll it using STM, and update it to ring at a different time than initially specified. It uses GHC event manager timeouts when available, yielding performance similar to threadDelay and registerDelay. Otherwise, it falls back to forked threads and threadDelay.

This package provides the ability to adapt to locale conventions such as date and time formats.

This package provides a simple text templating system used by pandoc.

This package provides a Haskell library including a couple of different implementations of mutable hash tables in the ST monad, as well as a typeclass abstracting their common operations, and a set of wrappers to use the hash tables in the IO monad.

Prior to base-4.7.0.0 there was no Eq instance for ErrorCall. This package provides an orphan instance.

This is a pretty printing library based on Wadler's paper "A Prettier Printer". It has been enhanced with support for ANSI terminal colored output using the ansi-terminal package.

A binding to libffi, allowing C functions of types only known at runtime to be called from Haskell.

A package for convenient access to high-resolution clock and timer functions of different operating systems via a unified API.

This package contains a backend for ghc-persistent using the MySQL database server. Internally it uses the ghc-mysql-simple and mysql packages in order to access the database. This package supports only MySQL 5.1 and above. However, it has been tested only on MySQL 5.5. Only the InnoDB storage engine is officially supported.

Contravariant functors for Haskell.

This package converts between bytestrings and their hexadecimal string representation.

This package defines a class, Hashable, for types that can be converted to a hash value. This class exists for the benefit of hashing-based data structures. The package provides instances for basic types and a way to combine hash values.

This package provides a regular expression toolkit for regex-base with compile-time checking of regular expression syntax, data types for matches and captures, a text replacement toolkit, portable options, high-level AWK-like tools for building text processing apps, regular expression macros with parsers and test bench, comprehensive documentation, tutorials and copious examples.

This package provides a typeclass with a single function that is designed to help convert between different types: numeric values, dates and times, and the like. The conversions perform bounds checking and return a pure Either value. This means that you need not remember which specific function performs the conversion you desire.
