The functions for creating temporary files and directories in the Haskelll base library are quite limited. This library just repackages the Cabal implementations of its own temporary file and folder functions so that you can use them without linking against Cabal or depending on it being installed.

This Haskell package provides extras for the ghc-contravariant package.

This library can load and store images in PNG, Bitmap, JPEG, Radiance, TIFF and GIF formats.

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 library provides access to system information and functionality to Lua scripts via Haskell's System module. Intended usage for this package is to preload it by adding the loader function to package.preload. Note that the Lua package library must have already been loaded before the loader can be added.

Haskell library for opening the web browser.

Parse jira wiki text into an abstract syntax tree for easy transformation to other formats.

This package provides bifunctors for Haskell.

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.

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

This package provides default instances for types from the base package.

This package allows simple reflection of expressions containing variables. Reflection here means that a Haskell expression is turned into a string. The primary aim of this package is teaching and understanding; there are no options for manipulating the reflected expressions beyond showing them.

This package provides a variety of alternative parser combinator libraries, including the original HuttonMeijer set. The Poly sets have features like good error reporting, arbitrary token type, running state, lazy parsing, and so on. Finally, Text.Parse is a proposed replacement for the standard Read class, for better deserialisation of Haskell values from Strings.

This package provides a quasiquoter for raw string literals, i.e. string literals that don't recognise the standard escape sequences. Basically, they make your code more readable by freeing you from the responsibility to escape backslashes. They are useful when working with regular expressions, DOS/Windows paths and markup languages (such as XML).

This package provides a basic random number generation library, including the ability to split random number generators.

This library encourages an error-handling style that directly uses the type system, rather than out-of-band exceptions.

This package contains basic primitives for the Foundation set of packages.

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

This Hackage security library provides both server and client utilities for securing the Hackage package server. It is based on The Update Framework, a set of recommendations developed by security researchers at various universities in the US as well as developers on the Tor project.

This Haskell package defines typeclasses used for converting Haskell data types to and from HTTP API data.

Haddock is a documentation-generation tool for Haskell libraries.

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.

This library defines a data structure for representing Jupyter notebooks, along with ToJSON and FromJSON instances for conversion to and from JSON .ipynb files.
