This package provides a custom prelude with no dependencies apart from the base package.

Foundation has the following goals:

1. provide a base like sets of modules that provide a consistent set of features and bugfixes across multiple versions of GHC (unlike base).

2. provide a better and more efficient prelude than base's prelude.

3. be self-sufficient: no external dependencies apart from base;

4. provide better data-types: packed unicode string by default, arrays;

5. Numerical classes that better represent mathematical things (no more all-in-one Num);

6. I/O system with less lazy IO.

This package provides fast unicode character sets for Haskell, based on complemented PATRICIA tries.

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 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.

The Scripting.Lua module is a wrapper of the Lua language interpreter as described in https://www.lua.org/.

Cheapskate is an experimental Markdown processor in pure Haskell. It aims to process Markdown efficiently and in the most forgiving possible way. It is designed to deal with any input, including garbage, with linear performance. Output is sanitized by default for protection against cross-site scripting (XSS) attacks.

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

This package provides access to ALSA infrastructure, that is needed by both alsa-seq and alsa-pcm.

This package is for working with the native byte-ordering of the system.

This library defines a data structure for representing Jupyter notebooks, along with ToJSON and FromJSON instances for conversion to and from JSON .ipynb files.

An implementation of the git-lfs protocol.

Efficient hashing-based container types. The containers have been optimized for performance critical use, both in terms of large data quantities and high speed.

This package provides a compatibility layer providing Binary instances for strict and lazy text types for versions older than 1.2.1 of the text package.

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

This Haskell package aims to be an RFC3986 compliant URI parser that uses ByteStrings for parsing and representing the URI data.

PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. Unlike many general-purpose RNGs, they are also hard to predict. . This library implements bindings to the standard C implementation. This includes the standard, unique, fast and single variants in the pcg family. There is a pure implementation that can be used as a generator with the random package as well as a faster primitive api that includes functions for generating common types. . The generators in this module are suitable for use in parallel but make sure threads don't share the same generator or things will go horribly wrong.

This package provides a low-level networking interface.

This package provides functions for signed 15.16 precision fixed point arithmetic.

In Haskell you very often acquire values using the with... idiom using functions of type (a -> IO r) -> IO r. This idiom forms a Monad, which is a special case of the ContT monad (from transformers) or the Codensity monad (from kan-extensions). The main purpose behind this package is to provide a restricted form of these monads specialized to this unusually common case.

The reason this package defines a specialized version of these types is to:

• be more beginner-friendly,

• simplify inferred types and error messages, and:

• provide some additional type class instances that would otherwise be orphan instances

This library provides support for parsing and generating BitTorrent files.

Haskell library for opening the web browser.

This library encourages an error-handling style that directly uses the type system, rather than out-of-band exceptions.

The conduit package is a solution to the streaming data problem, allowing for production, transformation, and consumption of streams of data in constant memory. It is an alternative to lazy I/O which guarantees deterministic resource handling, and fits in the same general solution space as enumerator/iteratee and pipes.
