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

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

Various tasty helpers and utilities to test HsLua oparations. Built on top of tasty-hunit.

This library provides a continuation-based, backtracking, logic programming monad. An adaptation of the two-continuation implementation found in the paper "Backtracking, Interleaving, and Terminating Monad Transformers" available online.

This package provides functions for converting emoji names to emoji characters and vice versa.

How does it differ from the emoji package?

• It supports a fuller range of emojis, including all those supported by GitHub

• It supports lookup of emoji aliases from emoji

• It uses Text rather than String

• It has a lighter dependency footprint: in particular, it does not require aeson

• It does not require TemplateHaskell

This package provides a pure interface for compressing and decompressing LZMA streams of data represented as lazy ByteStrings. A monadic incremental interface is provided as well.

This package profides a class for encoding and decoding UTF8 strings with instances for several common types. It also includes several functions for working with UTF8. It aims to be lightweight, depending only on Base and including only one module.

This library parses and dumps documents that are formatted according to RFC 4180, The common Format and MIME Type for Comma-Separated Values (CSV) Files. This format is used, among many other things, as a lingua franca for spreadsheets, and for certain web services.

Haskell library for opening the web browser.

A package for convenient access to high-resolution clock and timer functions of different operating systems via a unified API.

The premise of basic-prelude is that there are a lot of very commonly desired features missing from the standard Prelude, such as commonly used operators (<$> and >=>, for instance) and imports for common datatypes (e.g., ByteString and Vector). At the same time, there are lots of other components which are more debatable, such as providing polymorphic versions of common functions.

So basic-prelude is intended to give a common foundation for a number of alternate preludes. The package provides two modules: CorePrelude provides the common ground for other preludes to build on top of, while BasicPrelude exports CorePrelude together with commonly used list functions to provide a drop-in replacement for the standard Prelude.

Users wishing to have an improved Prelude can use BasicPrelude. Developers wishing to create a new prelude should use CorePrelude.

This package normalizes variations in the interface for inspecting datatype information via Template Haskell so that packages and support a single, easier to use informational datatype while supporting many versions of Template Haskell.

This library contains simple and easy-to-use primitives for I/O using streams.

The base library exposes the hGetEcho and hSetEcho functions for querying and setting echo status, but unfortunately, neither function works with MinTTY consoles on Windows. This library provides an alternative interface which works with both MinTTY and other consoles.

Async provides a library to run IO operations asynchronously, and wait for their results. It is a higher-level interface over threads in Haskell, in which Async a is a concurrent thread that will eventually deliver a value of type a.

This library provides Haskell bindings to the Zstandard compression algorithm, a fast lossless compression algorithm targeting real-time compression scenarios at zlib-level and better compression ratios.

This package provides testing utilities that are useful in conjunction with the Validity typeclass.

This package provides Haskell bindings to bibutils, a library that interconverts between various bibliography formats using a common MODS-format XML intermediate.

This library provides implementations of concurrent FIFO queues (for both general boxed and primitive unboxed values) that are fast, perform well under contention, and offer a Chan-like interface. The library may be of limited usefulness outside of x86 architectures where the fetch-and-add instruction is not available.

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

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

This package (formerly binary-serialise-cbor) provides pure, efficient serialization of Haskell values directly into ByteStrings for storage or transmission purposes. By providing a set of type class instances, you can also serialise any custom data type you have as well.

The underlying binary format used is the 'Concise Binary Object Representation', or CBOR, specified in RFC 7049. As a result, serialised Haskell values have implicit structure outside of the Haskell program itself, meaning they can be inspected or analyzed without custom tools.

An implementation of the standard bijection between CBOR and JSON is provided by the https://hackage.haskell.org/package/cborg-json package. Also see https://hackage.haskell.org/package/cbor-tool for a convenient command-line utility for working with CBOR data.

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