A UTF8 layer for Strings. The utf8-string package provides operations for encoding UTF8 strings to Word8 lists and back, and for reading and writing UTF8 without truncation.

Provides default instances for types from the containers package.

This package provides a low-level networking interface.

This library provides the functions to find unique and duplicate elements in a list.

This library provides Comonads for Haskell.

The package provides mutable and immutable bit arrays.

This library provides core modules of a markup combinator library for Haskell.

This package provides some handy Template Haskell splices for including the current git hash and branch in the code of your project. This is useful for including in panic messages, --version output, or diagnostic info for more informative bug reports.

This package provides Haskell bindings to your system's native wcwidth and a command line tool to examine the widths assigned by it. The command line tool can compile a width table to Haskell code that assigns widths to the Char type.

This library provides support for parsing and generating BitTorrent files.

Experimental Hspec support for testing WAI applications

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

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 package provides utilities and combinators for parsing command line options in Haskell.

This package contains bindings to the SDL 2 library, in both high- and low-level forms. The SDL namespace contains high-level bindings, where enumerations are split into sum types, and we perform automatic error-checking. The SDL.Raw namespace contains an almost 1-1 translation of the C API into Haskell FFI calls. As such, this does not contain sum types nor error checking. Thus this namespace is suitable for building your own abstraction over SDL, but is not recommended for day-to-day programming.

This library provides a utility function liftType, which accepts a type application argument and returns the Template Haskell Type representation of it.

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 a functional library for creating efficient memo functions using tries.

This package provides a new data structure for accurate on-line accumulation of rank-based statistics such as quantiles and trimmed means. . See original paper: "Computing extremely accurate quantiles using t-digest" by Ted Dunning and Otmar Ertl for more details <https://github.com/tdunning/t-digest/blob/07b8f2ca2be8d0a9f04df2feadad5ddc1bb73c88/docs/t-digest-paper/histo.pdf>.

This package provides a Haskell wrapper over the LibYAML C library.

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

Clear to write, read and edit Haskell DSL for HTML.

• Names are consistent, and do not conflict with base or are keywords (all have suffix -).

• Same combinator can be used for attributes and elements (e.g. style_).

This is a Haskell library to derive Template Haskell's Lift class for datatypes.

This Haskell library algorithms for vector arrays.
