Haskell Development Project for openSUSE:Factory

Haskell is a standardized purely functional programming language with non-strict semantics, named after the logician Haskell Curry. It is one of the more popular functional languages, and the lazy functional language on which the most research is being performed. This is a development project for openSUSE:Factory that contains only the most essential tools to set up a Haskell development environment, like ghc, cabal-install, and their respective dependencies. This repository is supposed to be small and manageable. https://download.opensuse.org/repositories/devel:/languages:/haskell/openSUSE_Tumbleweed/ openSUSE:Factory

Tumbleweed is the ultimate rolling release distribution, providing the latest software as it’s released, built upon a foundation of world-class stability and testing. * Always Current: Get the newest kernel, IDEs, desktops, and applications automatically. * Powerfully Stable: Experience the velocity of a rolling release without sacrificing the reliability you depend on. * Engineered for Professionals: The top choice for Developers, Power Users, and openSUSE Contributors who need the best tools for the job. If you demand the latest stable software, your choice is Tumbleweed. Staging dashboard is located at: https://build.opensuse.org/staging_workflows/openSUSE:Factory List of known devel projects: https://build.opensuse.org/package/view_file/openSUSE:Factory:Staging/dashboard/devel_projects Have a look at http://en.opensuse.org/Portal:Factory for more details. https://download.opensuse.org/tumbleweed/repo/oss/ ghc-QuickCheck

Automatic testing of Haskell programs

QuickCheck is a library for random testing of program properties. The programmer provides a specification of the program, in the form of properties which functions should satisfy, and QuickCheck then tests that the properties hold in a large number of randomly generated cases. Specifications are expressed in Haskell, using combinators provided by QuickCheck. QuickCheck provides combinators to define properties, observe the distribution of test data, and define test data generators. Most of QuickCheck's functionality is exported by the main "Test.QuickCheck" module. The main exception is the monadic property testing library in "Test.QuickCheck.Monadic". If you are new to QuickCheck, you can try looking at the following resources: * The <http://www.cse.chalmers.se/~rjmh/QuickCheck/manual.html official QuickCheck manual>. It's a bit out-of-date in some details and doesn't cover newer QuickCheck features, but is still full of good advice. * <https://begriffs.com/posts/2017-01-14-design-use-quickcheck.html>, a detailed tutorial written by a user of QuickCheck. The <https://hackage.haskell.org/package/quickcheck-instances quickcheck-instances> companion package provides instances for types in Haskell Platform packages at the cost of additional dependencies.
