This package provides Haskell modules for accessing and manipulating fields of records.

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

The zip-archive library provides functions for creating, modifying, and extracting files from zip archives in Haskell.

This library provides file handling utilities for Haskell.

Wrapper for the Data.Version.Version Haskell type.

This package provides a UTF-8 aware subset of Lua's string module for Haskell. The functions provided by this module are upper, lower, len, reverse, and sub.

GHC 7.4 gave us the ability to talk about ConstraintKinds. They stopped crashing the compiler in GHC 7.6. This package provides a vocabulary for working with them.

This package provides helper functions for working with haskell-src-exts trees.

This library provides mechanisms to efficiently run periodic, on-demand actions in Haskell.

This package contains basic primitives for the Foundation set of packages.

Reasonably fast data encoding library.

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.

FoldMap lists are lists represented by their foldMap function. FoldMap lists have O(1) cons, snoc and append, just like DLists, but other operations might have favorable performance characteristics as well. These wild claims are still completely unverified though.

This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible. The library exposes a van Laarhoven interface. For an alternative interface, supporting an opaque optic type, see generic-optics.

This Haskell package includes tools for generating and consuming feeds in both RSS (Really Simple Syndication) and Atom format.

This package works as a prelude replacement for Haskell, providing more functionality and types out of the box than the standard prelude (such as common data types like ByteString and Text), as well as removing common ``gotchas'', like partial functions and lazy I/O. The guiding principle here is:

• If something is safe to use in general and has no expected naming conflicts, expose it.

• If something should not always be used, or has naming conflicts, expose it from another module in the hierarchy.

This package provides a basic random number generation library, including the ability to split random number generators.

A cross-platform library for retrieving information about disk space usage.

This package allows you to work with WAVE and RF64 files in Haskell.

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read and write Markdown and (subsets of) other formats, such as HTML, reStructuredText, LaTeX, DocBook, and many more.

Pandoc extends standard Markdown syntax with footnotes, embedded LaTeX, definition lists, tables, and other features. A compatibility mode is provided for those who need a drop-in replacement for Markdown.pl.

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.

This Haskell package provides extras for the ghc-contravariant package.

This package provides several functions to quickly search for substrings in strict or lazy ByteStrings. It also provides functions for breaking or splitting on substrings and replacing all occurrences of a substring (the first in case of overlaps) with another.

This library provides Haskell bindings to the MySQL mysqlclient client library. It is a fairly faithful, low level library that implements most of the MySQL client API. The major departure from the C API is that in Haskell, resource management is mostly automatic and safe.

This library deliberately avoids the question of providing a ``good'' API. Its purpose is to serve as a base upon which higher-level libraries can be built.
