This Haskell package lets you automatically generate lenses for data types; code was extracted from the lens package, and therefore generated lenses are fully compatible with ones generated by lens (and can be used both from lens and microlens).

ghc-citeproc parses Citation Style Language style files and uses them to generate a list of formatted citations and bibliography entries. For more information about CSL, see https://citationstyles.org/.

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

Provides default instances for types from the dlist package.

This library provides an easy way to define command line parsers.

This package endows Data.Time, from the time package, with several data types and functions for enhanced processing of timezones. For one way to create timezone series, see the ghc-timezone-olson package.

This package provides an API to Haddock, the documentation-generation tool for Haskell libraries.

This package provides a small cross-platform library for reading and modifying the system clipboard. It uses xclip or xsel at runtime.

This library provides a framework for size-based enumerations.

This package provides a quasiquoter for raw string literals, i.e. string literals that don't recognise the standard escape sequences. Basically, they make your code more readable by freeing you from the responsibility to escape backslashes. They are useful when working with regular expressions, DOS/Windows paths and markup languages (such as XML).

This package provides a simple logging abstraction that allows multiple back-ends.

This Haskell library contains type definitions for Universally Unique Identifiers or UUIDs, and basic conversion functions.

This module locates the full directory of the running program, to allow the use of paths relative to it. FindBin supports invocation of Haskell programs via "ghci", via "runhaskell/runghc", as well as compiled as an executable.

This package provides bindings to the ALSA simple mixer API.

Haddock is a documentation-generation tool for Haskell libraries.

This package provides a writer monad for multi-line string literals.

This Haskell package allows Haskell programs to access data storage systems like PostgreSQL, SQLite, and MariaDB in a type-safe way.

This package converts between bytestrings and their hexadecimal string representation.

This package allows you to have a README.md that at the same time is a literate Haskell program.

This library is simply a collection of linear-algebra related modules split from the statistics library.

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

A PointedList tracks the position in a non-empty list which works similarly to a zipper. A current item is always required, and therefore the list may never be empty. A circular PointedList wraps around to the other end when progressing past the actual edge.

This Haskell library offers (among other things) the following selection of synchronisation primitives:

• Broadcast: Wake multiple threads by broadcasting a value.

• Event: Wake multiple threads by signalling an event.

• Lock: Enforce exclusive access to a resource. Also known as a binary semaphore or mutex. The package additionally provides an alternative that works in the STM monad.

• RLock: A lock which can be acquired multiple times by the same thread. Also known as a reentrant mutex.

• ReadWriteLock: Multiple-reader, single-writer locks. Used to protect shared resources which may be concurrently read, but only sequentially written.

• ReadWriteVar: Concurrent read, sequential write variables.

Please consult the API documentation of the individual modules for more detailed information.

This package was inspired by the concurrency libraries of Java and Python.

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.
