Runtime exceptions - as exposed in base by the Control.Exception module - have long been an intimidating part of the Haskell ecosystem. This package is intended to overcome this. It provides a safe and simple API on top of the existing exception handling machinery. The API is equivalent to the underlying implementation in terms of power but encourages best practices to minimize the chances of getting the exception handling wrong.

This package defines a Language.Haskell.TH.Syntax.Compat module, which backports the Quote and Code types to work across a wide range of template-haskell versions. On recent versions of template-haskell (2.17.0.0 or later), this module simply re-exports Quote and Code from Language.Haskell.TH.Syntax.

This Haskell package provides striped pooling abstraction for managing flexibly-sized collections of resources such as database connections.

This library provides a number of common functions and types useful in statistics. We focus on high performance, numerical robustness, and use of good algorithms. Where possible, we provide references to the statistical literature.

The library's facilities can be divided into four broad categories:

• Working with widely used discrete and continuous probability distributions. (There are dozens of exotic distributions in use; we focus on the most common.)

• Computing with sample data: quantile estimation, kernel density estimation, histograms, bootstrap methods, significance testing, and regression and autocorrelation analysis.

• Random variate generation under several different distributions.

• Common statistical tests for significant differences between samples.

__This package is deprecated__. Please, use genByteString from the [random package (version >=1.2)](https://hackage.haskell.org/package/random) instead. . Efficient generation of random bytestrings. The implementation populates uninitialized memory with uniformily distributed random 64 bit words (and 8 bit words for remaining bytes at the end of the bytestring). . Random words are generated using the PRNG from the [mwc-random](https://hackage.haskell.org/package/mwc-random) package or the [pcg-random](https://hackage.haskell.org/package/pcg-random) package. It is also possible to use a custom PRNG by providing an instance for the RandomWords type class and using the function generate from the module "Data.ByteString.Random.Internal". . The generated byte strings are suitable for statistical applications. They are /not/ suitable for cryptographic applications. .  . 

This package provides distributive functors for Haskell. Dual to Traversable.

This package provides the Network.Multicast Haskell module for sending UDP datagrams over multicast (class D) addresses.

This package provides a compatibility layer for using GHC call stacks with different versions of the compiler.

This package provides utilities to inline C++ code into Haskell using inline-c.

ANSI terminal backend for the prettyprinter package.

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).

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

This Haskell package provides the core MonadUnliftIO typeclass, a number of common instances, and a collection of common functions working with it.

Per Conor McBride, the Newtype typeclass represents the packing and unpacking of a newtype, and allows you to operate under that newtype with functions such as ala'.

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 provides Haskell library for matching files using patterns such as \"src\/**\/*.png\" for all @file.png files recursively under the @filesrc directory.

Some of its features include:

• All matching is O(n).

• Most functions pre-compute some information given only one argument.

• Uses match and substitute to extract suitable strings from the * and ** matches, and substitutes them back into other patterns.

• Uses step and matchMany to perform bulk matching of many patterns against many paths simultaneously.

• Uses System.FilePattern.Directory to perform optimised directory traverals using patterns.

This library provides access to system information and functionality to Lua scripts via Haskell's System module. Intended usage for this package is to preload it by adding the loader function to package.preload. Note that the Lua package library must have already been loaded before the loader can be added.

When you've caught all the exceptions that can be handled safely, this is what you're left with.

This module provides set and multiset operations on ordered lists.

This package provides low-dependency functionality commonly needed by various Haskell streaming data libraries, such as conduit and pipes.

This library provides tools for ensuring that class members are shared.

Alternative parser for the Cassava package written with Megaparsec that provides for better error messages at the expense of some speed.

Fixpoint types and recursion schemes. If you define your AST as fixpoint type, you get fold and unfold operations for free.
