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

This package provides Haskell bindings to SDL2_image.

This package exports a module which is the recommended starting point for using microlens if you aren't trying to keep your dependencies minimal. By importing Lens.Micro.Platform you get all functions and instances from microlens, microlens-th, microlens-mtl, microlens-ghc, as well as instances for Vector, Text, and HashMap. The minor and major versions of microlens-platform are incremented whenever the minor and major versions of any other microlens package are incremented, so you can depend on the exact version of microlens-platform without specifying the version of microlens you need. This package is a part of the microlens family; see the readme on Github.

This library provides various semigroups, specialized containers and a general map/reduce framework for Haskell.

Pretty-simple is a pretty printer for Haskell data types that have a Show instance.

This is a pretty printing library based on Wadler's paper A Prettier Printer. This version allows the library user to declare overlapping instances of the Pretty class.

This package provides Type-level booleans.

This package converts between bytestrings and their hexadecimal string representation.

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.

In Haskell you very often acquire values using the with... idiom using functions of type (a -> IO r) -> IO r. This idiom forms a Monad, which is a special case of the ContT monad (from transformers) or the Codensity monad (from kan-extensions). The main purpose behind this package is to provide a restricted form of these monads specialized to this unusually common case.

The reason this package defines a specialized version of these types is to:

• be more beginner-friendly,

• simplify inferred types and error messages, and:

• provide some additional type class instances that would otherwise be orphan instances

Cross platform library for file creation, modification, and deletion notification. This library builds upon existing libraries for platform specific Windows, Mac, and Linux file system event notification.

The Newtype typeclass represents the packing and unpacking of a newtype, and allows you to operate under that newtype with functions such as ala. Generics support was added in version 0.4, making this package a full replacement for the original newtype package, and an alternative to newtype-th.

This library provides tools for reading and manipulating the .cabal file format. . Version 3.6 (unlike the following versions) is a dummy package that prevents module name clases between Cabal and Cabal-syntax if used together with a Cabal flag as described below. . In Cabal-3.7 this package was split off. To avoid module name clashes, you can add this to your .cabal file: . > flag Cabal-syntax > description: Use the new Cabal-syntax package > default: False > manual: False > > library > -- ... > if flag(Cabal-syntax) > build-depends: Cabal-syntax >= 3.7 > else > build-depends: Cabal < 3.7, Cabal-syntax < 3.7 . This will default to the older build, but will allow consumers to opt-in to the newer libraries by requiring Cabal or Cabal-syntax >= 3.7

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

This library provides Haskell bindings to the MySQL mysqlclient client library. It is a fairly faithful, low level library that implements most of the MySQL client API. The major departure from the C API is that in Haskell, resource management is mostly automatic and safe.

This library deliberately avoids the question of providing a ``good'' API. Its purpose is to serve as a base upon which higher-level libraries can be built.

This library provides opaque unique identifiers in primitive state monads and a GADT-like type using them as witnesses of type equality.

This library provides Haskell bindings for the OpenGL Utility Toolkit, a window system-independent toolkit for writing OpenGL programs.

This package provides a simple compatibility shim that lets you work with both binary and cereal with one chunk of serialization code.

This library provides a wide array of (semi)groupoids and operations for working with them. A Semigroupoid is a Category without the requirement of identity arrows for every object in the category. A Category is any Semigroupoid for which the Yoneda lemma holds. Finally, to work with these weaker structures it is beneficial to have containers that can provide stronger guarantees about their contents, so versions of Traversable and Foldable that can be folded with just a Semigroup are added.

Types that are parametric on a functor are like Barbies that have an outfit for each role. This package provides the basic abstractions to work with them comfortably.

Implementation of bidirectional TOML serialization.

Provides generalisations of swap :: (a,b) -> (b,a) and assoc :: ((a,b),c) -> (a,(b,c)) to Bifunctors supporting similar operations (e.g. Either, These).

This library provides extra functions for the standard Haskell libraries. Most functions are simple additions, filling out missing functionality. A few functions are available in later versions of GHC, but this package makes them available back to GHC 7.2.

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