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

This package provides various extra monoid-related definitions and utilities, such as monoid actions, monoid coproducts, semi-direct products, "deletable" monoids, "split" monoids, and "cut" monoids.

This package provides types and combinators for linear algebra on free vector spaces.

ghc-doctest-driver-gen is a Doctest's driver file generator. It lets you automatically generate driver file for Doctest's Cabal integration.

This package provides efficient vector-based hashtable implementation similar to .NET Generic Dictionary implementation (at the time of 2015).

This package contains basic definitions related to indexed profunctors. These are primarily intended as internal utilities to support the optics and generic-lens package families.

This library provides a datatype which can be interpreted by apply-refact. It exists as a separate library so that applications can specify refactorings without depending on GHC.

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 library provides a half-precision floating-point computation library for Haskell.

This library provides a type-safe embedded domain specific language (EDSL) for SQL queries that works with SQL backends as provided by ghc-persistent. Its language closely resembles SQL, so you don't have to learn new concepts, just new syntax, and it's fairly easy to predict the generated SQL and optimize it for your backend.

Atomically write to a file on POSIX-compliant systems while preserving permissions. mv is an atomic operation. This makes it simple to write to a file atomically just by using the mv operation. However, this will destroy the permissions on the original file. This library preserves permissions while atomically writing to a file.

This library provides fast base64 encoding and decoding for Haskell ByteStrings.

This package provides functions to prevent or capture writing to stdout and other handles.

Haskell library for opening the web browser.

This Haskell package was originally present in classy-prelude.

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

Utilities for dealing with IEEE floating point numbers, ported from the Tango math library; approximate and exact equality comparisons for general types.

This library provides support for parsing and generating BitTorrent files.

This library provides Haskell bindings for checking currently mounted filesystems.

Convenience functions and TH for working with constraints. See README.md for example usage.

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

This package provides a library for parallel programming.

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