Shake is a Haskell library for writing build systems - designed as a replacement for make. To use Shake the user writes a Haskell program that imports the Shake library, defines some build rules, and calls shake. Thanks to do notation and infix operators, a simple Shake program is not too dissimilar from a simple Makefile. However, as build systems get more complex, Shake is able to take advantage of the excellent abstraction facilities offered by Haskell and easily support much larger projects. The Shake library provides all the standard features available in other build systems, including automatic parallelism and minimal rebuilds. Shake provides highly accurate dependency tracking, including seamless support for generated files, and dependencies on system information (e.g. compiler version).

This Haskell package provides ShowQ, ShowFun, and SimpleReflect. * ShowFun gives a Typeable-dependent instance for showing functions as their type. * ShowIO does the same for IO actions. * ShowQ adds SmallCheck & QuickCheck support. * SimpleReflect allows us to literally see how functions 'expand', through appropriate Show magic.

Prevent or capture writing to stdout and other handles.

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.

SmallCheck is a testing library that allows to verify properties for all test cases up to some depth. The test cases are generated automatically by SmallCheck.

A collection of various methods for splitting lists into parts, akin to the "split" function found in several mainstream languages. Here is its tale: Once upon a time the standard Data.List module held no function for splitting a list into parts according to a delimiter. Many a brave lambda-knight strove to add such a function, but their striving was in vain, for Lo, the Supreme Council fell to bickering amongst themselves what was to be the essential nature of the One True Function which could cleave a list in twain (or thrain, or any required number of parts). And thus came to pass the split package, comprising divers functions for splitting a list asunder, each according to its nature. And the Supreme Council had no longer any grounds for argument, for the favored method of each was contained therein. Combinator library and utility functions for splitting lists.

Additional types of channels for STM.

A modular composable concurrency abstraction.

This package contains the generics system described in the "Scrap Your Boilerplate" papers. It defines the "Data" class of types permitting folding and unfolding of constructor applications, instances of this class for primitive types, and a variety of traversals.

Provides low-dependency functionality commonly needed by various streaming data libraries, such as conduit and pipes.
