This Haskell package provides a replacement for Data.Conduit.List, as well as a convenient Conduit module.

Utilities for dealing with IEEE floating point numbers, ported from the Tango math library; approximate and exact equality comparisons for general types.

This package provides a configuration management library for programs and daemons. The features include:

1. Automatic, dynamic reloading in response to modifications to configuration files.

2. A simple, but flexible, configuration language, supporting several of the most commonly needed types of data, along with interpolation of strings from the configuration or the system environment (e.g. $(HOME)).

3. Subscription-based notification of changes to configuration properties.

4. An import directive allows the configuration of a complex application to be split across several smaller files, or common configuration data to be shared across several applications.

A cross-platform library with functions for adjusting code pages on Windows. On all other operating systems, the library does nothing.

SmallCheck is a testing library that verifies properties for all test cases up to some depth. The test cases are generated automatically by SmallCheck.

Compatibility layer for Data.Array.Byte providing boxed wrappers for ByteArray and MutableByteArray and relevant instances for GHC < 9.4.

Pandoc-server provides pandoc's document conversion functions in an HTTP server.

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>.

OpenGLRaw is a raw Haskell binding for the OpenGL 4.5 graphics system and lots of OpenGL extensions. It is basically a 1:1 mapping of OpenGL's C API, intended as a basis for a nicer interface. OpenGLRaw offers access to all necessary functions, tokens and types plus a general facility for loading extension entries. The module hierarchy closely mirrors the naming structure of the OpenGL extensions, making it easy to find the right module to import. All API entries are loaded dynamically, so no special C header files are needed for building this package. If an API entry is not found at runtime, a userError is thrown.

This package provides extra instances for type-classes in the [indexed-traversable](https://hackage.haskell.org/package/indexed-traversable) package. . The intention is to keep this package minimal; it provides instances that formerly existed in @lens@ or @optics-extra@. We recommend putting other instances directly into their defining packages. The @indexed-traversable@ package is light, having only GHC boot libraries as its dependencies.

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

This package defines new symbols for a number of functions, operators and types in the base package. All symbols are documented with their actual definition and information regarding their Unicode code point. They should be completely interchangeable with their definitions. For further Unicode goodness you can enable the UnicodeSyntax language extension. This extension enables Unicode characters to be used to stand for certain ASCII character sequences, i.e. → instead of ->, ∀ instead of forall and many others.

This package provides bindings to the ALSA simple mixer API.

This Haskell package provides a family of type-safe templates with simple variable interpolation. Shakespeare templates can be used inline with a quasi-quoter or in an external file and it interpolates variables according to the type being inserted.

This package provides functionality for generalising the deriving mechanism in Haskell to arbitrary classes.

wordexp(3) wrapper library for Haskell to perform word expansion like a posix-shell.

The documentation of System.Environment.getProgName says that "However, this is hard-to-impossible to implement on some non-Unix OSes, so instead, for maximum portability, we just return the leafname of the program as invoked." This library tries to provide the missing path.

The module Data.CaseInsensitive provides the CI type constructor which can be parameterised by a string-like type like: String, ByteString, Text, etc. Comparisons of values of the resulting type will be insensitive to cases.

This library provides data structures for describing changes to other data structures. In this library, a patch is something that can be applied, analogous to a function, and which distinguishes returning the argument it was provided from returning something else.

Haskell library for opening the web browser.

This package provides a data type These a b which can hold a value of either type or values of each type. This is usually thought of as an "inclusive or" type (contrasting Either a b as "exclusive or") or as an "outer join" type (contrasting (a, b) as "inner join").

data These a b = This a | That b | These a b

Since version 1, this package was split into parts:

• https://hackage.haskell.org/package/semialign For Align and Zip type-classes.

• https://hackage.haskell.org/package/semialign-indexed For SemialignWithIndex class, providing ialignWith and izipWith

• https://hackage.haskell.org/package/these-lens For lens combinators.

• http://hackage.haskell.org/package/monad-chronicle For transformers variant of These.

Uniplate is a library for writing simple and concise generic operations. Uniplate has similar goals to the original Scrap Your Boilerplate work, but is substantially simpler and faster.

Haskell bindings to the International Components for Unicode (ICU) libraries. These libraries provide robust and full-featured Unicode services on a wide variety of platforms. . Features include: . * Both pure and impure bindings, to allow for fine control over efficiency and ease of use. . * Breaking of strings on character, word, sentence, and line boundaries. . * Access to the Unicode Character Database (UCD) of character metadata. . * String collation functions, for locales where the conventions for lexicographic ordering differ from the simple numeric ordering of character codes. . * Character set conversion functions, allowing conversion between Unicode and over 220 character encodings. . * Unicode normalization. (When implementations keep strings in a normalized form, they can be assured that equivalent strings have a unique binary representation.) . * Regular expression search and replace. . * Security checks for visually confusable (spoofable) strings. . * Bidirectional Unicode algorithm . * Calendar objects holding dates and times. . * Number and calendar formatting.

Haskell library for both generating and consuming project templates.

ost IDEs provide the concept of a project template: instead of writing all of the code for a project from scratch, you select a template, answer a few questions, and a bunch of files are automatically generated.

project-template tries to provide a canonical Haskell library for implementing the ideal templating system.
