This is a terminal client for the Mattermost chat system.

HLint reads Haskell programs and suggests changes that hopefully make them easier to read. HLint also makes it easy to disable unwanted suggestions, and to add your own custom suggestions.

HSColour is a small Haskell script to colourise Haskell code. It currently has six output formats: ANSI terminal codes (optionally XTerm-256colour codes), HTML 3.2 with font tags, HTML 4.01 with CSS, HTML 4.01 with CSS and mouseover annotations, XHTML 1.0 with inline CSS styling, LaTeX, and mIRC chat codes.

greenclip is a clipboard manager written in Haskell.

The cabal command-line program simplifies the process of managing Haskell software by automating the fetching, configuration, compilation and installation of Haskell libraries and programs.

Hoogle is a Haskell API search engine, which allows you to search many standard Haskell libraries by either function name, or by approximate type signature.

Project Raincat is a game developed by Carnegie Mellon students through GCS during the Fall 2008 semester. Raincat features game play inspired from classics Lemmings and The Incredible Machine. The project proved to be an excellent learning experience for the programmers. Everything is programmed in Haskell.

This package lets you perform refactorings specified by the refact library. It is primarily used with HLint's --refactor flag.

Stylish-haskell is a Haskell code prettifier. The goal is not to format all of the code in a file, to avoid "getting in the way". However, this tool can e.g. clean up import statements and help doing various tasks that get tedious very quickly. It can

• Align and sort import statements

• Group and wrap -# LANGUAGE #- pragmas, remove (some) redundant pragmas

• Remove trailing whitespaces

• Align branches in case and fields in records

• Convert line endings (customisable)

• Replace tabs by four spaces (turned off by default)

• Replace some ASCII sequences by their Unicode equivalent (turned off by default)

This package allows managing files with Git, without checking the file contents into Git. It can store files in many places, such as local hard drives and cloud storage services. It can also be used to keep a folder in sync between computers.

This package allows on to run Doctests in a Cabal.Test.exitcode-stdio environment.

This Haskell library provides convenient assertions with pretty-printed failure messages for QuickCheck properties, that are similar to those of HUnit.

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 defined in the QuickCheck library.

This package gives users the ability to define tasty tests from Lua.

To properly work, the doctest package needs plenty of configuration. This library provides the common bits for writing custom Setup.hs files.

This library is a minimal variant of `quickcheck-classes` that only provides laws for typeclasses from `base`. The main purpose of splitting this out is so that `primitive` can depend on `quickcheck-classes-base` in its test suite, avoiding the circular dependency that arises if `quickcheck-classes` is used instead. This library provides QuickCheck properties to ensure that typeclass instances adhere to the set of laws that they are supposed to. There are other libraries that do similar things, such as `genvalidity-hspec` and `checkers`. This library differs from other solutions by not introducing any new typeclasses that the user needs to learn. Note: on GHC < 8.5, this library uses the higher-kinded typeclasses (Data.Functor.Classes.Show1, Data.Functor.Classes.Eq1, Data.Functor.Classes.Ord1, etc.), but on GHC >= 8.5, it uses `-XQuantifiedConstraints` to express these constraints more cleanly.

This package provides HUnit support for the test-framework package.

This package allows tests such as QuickCheck properties and HUnit test cases to be assembled into test groups, run in parallel (but reported in deterministic order, to aid diff interpretation) and filtered and controlled by command line options. All of this comes with colored test output, progress reporting and test statistics output.

This package provides a Tasty provider for Hspec test suites.

HUnit is a unit testing framework for Haskell, inspired by the JUnit tool for Java.

Feat (Functional Enumeration of Algebraic Types) provides enumerations as functions from natural numbers to values (similar to toEnum but for any algebraic data type). This can be used for SmallCheck-style systematic testing, QuickCheck-style random testing, and hybrids of the two.

This package provides contributed Hspec extensions.

This package provides a Known Answer Tests (KAT) framework for tasty.
