This package implements a language similar to YAML or JSON but with fewer special cases and fewer dependencies. It emphasizes layout structure for sections and lists, and requires quotes around strings.

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.

This package provides a plotting library for Haskell, using gnuplot for rendering.

This package provides a simple text templating system used by pandoc.

This Haskell package provides support for computations which consume random values.

Provides an efficient Haskell implementation of Peano numbers

This library provides free monads, which are useful for many tree-like structures and domain specific languages. If f is a Functor then the free Monad on f is the type of trees whose nodes are labeled with the constructors of f. The word "free" is used in the sense of "unrestricted" rather than "zero-cost": Free f makes no constraining assumptions beyond those given by f and the definition of Monad.

This package defines a class for types with a default value, and provides instances for types from the base, containers, dlist and old-locale packages.

regex-applicative is a Haskell library for parsing using regular expressions. Parsers can be built using Applicative interface.

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.

This package defines orphan instances that mimic instances available in later versions of base to a wider (older) range of compilers.

Takes an error-throwing expression and puts it back in the Maybe it belongs in.

Note that this suffers from the https://ghc.haskell.org/trac/ghc/ticket/5902. Buyer beware.

This package provides basic types for representing XML documents.

This package provides a quasi-quoter for raw SQL for ghc-persistent.

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 contains the C sources of LPeg, as well as some tiny Haskell helper to load the package. . <http://www.inf.puc-rio.br/~roberto/lpeg/>

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

This package provides Haskell APIs to efficiently access the <https://www.unicode.org/ucd/ Unicode character database> (UCD). Performance is the primary goal in the design of this package. The Haskell data structures are generated programmatically from the UCD files.

For examples and an introduction to the library please take a look at the <https://github.com/CRogers/should-not-typecheck#should-not-typecheck- README> on github.

This package provides a small cross-platform library for reading and modifying the system clipboard. It uses xclip or xsel at runtime.

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 library provides higher order versions of Prelude classes to ease programming with polymorphic recursion and reduce UndecidableInstances.

This package provides IO operations from async package lifted to any instance of MonadBase or MonadBaseControl.

This library provides tools to calculate various string metrics efficiently.
