Network.HostName is a simple package providing a means to determine the hostname.

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

This package provides a Haskell library for globbing: matching patterns against file paths.

This package provides a stronger variant of `traverse` which can remove elements and generalised mapMaybe, catMaybes, filter

This package provides a Haskell type inhabited by finitely many values and indexed by type-level naturals.

This package provides a fully compliant Haskell 98 lexer.

This package supplements the Validity typeclass with standard properties for functions operating on them.

This package provides a drop-in replacement for the standard filepath library, operating on RawFilePath values rather than FilePath values to get the speed benefits of using ByteStrings.

Provides default instances for types from the dlist package.

This Haskell package contains code for generating high quality random numbers that follow either a uniform or normal distribution. The generated numbers are suitable for use in statistical applications.

The uniform PRNG uses Marsaglia's MWC256 (also known as MWC8222) multiply-with-carry generator, which has a period of 2^8222 and fares well in tests of randomness. It is also extremely fast, between 2 and 3 times faster than the Mersenne Twister.

Monad classes using type families, with instances for various monad transformers, inspired by the paper 'Functional Programming with Overloading and Higher-Order Polymorphism', by Mark P Jones. This package is almost a compatible replacement for the mtl-tf package.

This is an implementation of Tarjan's Union-Find algorithm (Robert E.: Tarjan. "Efficiency of a Good But Not Linear Set Union Algorithm",JACM 22(2), 1975) in order to maintain an equivalence relation. This implementation is a port of the union-find package using the ST monad transformer (instead of the IO monad).

A priority search queue efficiently supports the operations of both a search tree and a priority queue. A Binding is a product of a key and a priority. Bindings can be inserted, deleted, modified and queried in logarithmic time, and the binding with the least priority can be retrieved in constant time. A queue can be built from a list of bindings, sorted by keys, in linear time.

This package provides bindings to the ALSA simple mixer API.

This package provides a simple compatibility shim that lets you work with both binary and cereal with one chunk of serialization code.

Shelly provides convenient systems programming in Haskell, similar in spirit to POSIX shells. Shelly is originally forked from the Shellish package.

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 algorithms on Conduits, including higher level asynchronous processing and some other utilities.

This package provides Haskell APIs to efficiently access the <https://www.unicode.org/ucd/ Unicode character database> (UCD). Performance is the primary goal in the design of this package. The Haskell data structures are generated programmatically from the UCD files.

This package provides an abstraction for communicating with line-oriented network services while abstracting over the use of SOCKS5 and TLS (via OpenSSL)

This library is for working with \".tar\" archive files. It can read and write a range of common variations of the tar archive format including V7, POSIX USTAR and GNU formats. It provides support for packing and unpacking portable archives. This makes it suitable for distribution but not backup because details like file ownership and exact permissions are not preserved. It also provides features for random access to archive content using an index.

This library provides a wrapper to mmap, allowing files or devices to be lazily loaded into memory as strict or lazy ByteStrings, ForeignPtrs or plain Ptrs, using the virtual memory subsystem to do on-demand loading.

This module allows tokens produced by skylighting-core to be rendered as LaTeX macros.

ghc-blaze-textual is a fast Haskell library for rendering common Haskell datatypes in text form using the ghc-blaze-builder library.
