This package provides an orphan instance that allows you to use HUnit assertions as QuickCheck properties.

ghc-quickcheck-unicode 1.0.0.1 — Generator functions Unicode-related tests

This package provides generator and shrink functions for testing Unicode-related software.

ghc-random 1.1 — Random number library

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

ghc-rebase 1.1 — Progressive alternative to the base package for Haskell

This Haskell package is intended for those who are tired of keeping long lists of dependencies to the same essential libraries in each package as well as the endless imports of the same APIs all over again.

It also supports the modern tendencies in the language.

To solve those problems this package does the following:

  • Reexport the original APIs under the Rebase namespace.

  • Export all the possible non-conflicting symbols from the Rebase.Prelude module.

  • Give priority to the modern practices in the conflicting cases.

The policy behind the package is only to reexport the non-ambiguous and non-controversial APIs, which the community has obviously settled on. The package is intended to rapidly evolve with the contribution from the community, with the missing features being added with pull-requests.

One module layer over regex-tdfa to replace Text.Regex. regex-compat can't use Unicode characters correctly because of using regex-posix. This is not good for Unicode users. This modified regex-compat uses regex-tdfa to solve this problem.

ghc-regex-pcre-builtin 0.94.4.8.8.35 — Enhancement of the builtin Text.Regex library

This library implements unicode-casemap, the simple, non locale-sensitive unicode collation algorithm described in RFC 5051. Proper unicode collation can be done using text-icu, but that is a big dependency that depends on a large C library, and rfc5051 might be better for some purposes.

ghc-safe 0.3.9 — Library of safe (exception free) functions

This library provides wrappers around Prelude and Data.List functions, such as head and !!, that can throw exceptions.

ghc-sandi 0.4.0 — Data encoding library

ghc-semigroupoids 5.0.0.4 — Semigroupoids operations 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.

ghc-semigroups 0.18.2 — Semigroup operations for Haskell

This package provides semigroups for Haskell. In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation. A semigroup generalizes a monoid in that there might not exist an identity element. It also (originally) generalized a group (a monoid with all inverses) to a type where every element did not have to have an inverse, thus the name semigroup.

ghc-setenv 0.1.1.3 — Library for setting environment variables

This package provides a Haskell library for setting environment variables.

This package provides Haskell bindings to the setlocale C function.

The functions have been tested against most of the NIST and RFC test vectors for the various functions. While some attention has been paid to performance, these do not presently reach the speed of well-tuned libraries, like OpenSSL.

ghc-shelly 1.6.8 — Shell-like (systems) programming in Haskell

Shelly provides convenient systems programming in Haskell, similar in spirit to POSIX shells. Shelly is originally forked from the Shellish package.

  • Computing with sample data: quantile estimation, kernel density estimation, histograms, bootstrap methods, significance testing, and regression and autocorrelation analysis.

  • Random variate generation under several different distributions.

  • Common statistical tests for significant differences between samples.

This is a small wrapper around the directory, unix, and Win32 packages, for use with system-filepath. It provides a consistent API to the various versions of these packages distributed with different versions of GHC. In particular, this library supports working with POSIX files that have paths which can't be decoded in the current locale encoding.

ghc-system-filepath 0.4.13.4 — High-level, byte-based file and directory path manipulations

Provides a FilePath datatype and utility functions for operating on it. Unlike the filepath package, this package does not simply reuse String, increasing type safety.

This library is for working with \".tar\" archive files. It can read and write a range of common variations of the tar archive format including V7, POSIX USTAR and GNU formats.

ghc-temporary 1.2.0.3 — Temporary file and directory support

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.

ghc-temporary-rc 1.2.0.3 — Portable temporary file and directory support

The functions for creating temporary files and directories in the base library are quite limited. The unixutils package contains some good ones, but they aren't portable to Windows. 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 is a better maintained fork of the "temporary" package.

defaultMainGenerator will extract all functions beginning with case_, prop_, or test_ in the module and put them in a testGroup.

testGroupGenerator is like defaultMainGenerator but without defaultMain. It is useful if you need a function for the testgroup (e.g. if you want to be able to call the testgroup from another module).

ghc-texmath 0.8.6.5 — Conversion between formats used to represent mathematics

The texmath library provides functions to read and write TeX math, presentation MathML, and OMML (Office Math Markup Language, used in Microsoft Office).
