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.

A modular composable concurrency abstraction.

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.

HUnit support for the test-framework 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 contains an implementation of a high-quality splittable pseudorandom number generator. The generator is based on a cryptographic hash function built on top of the ThreeFish block cipher.

ThreadScope is a graphical viewer for thread profile information generated by the Glasgow Haskell Compiler (GHC). The ThreadScope program allows us to debug the parallel performance of Haskell programs. Using Threadscope we can check to see that work is well balanced across the available processors and spot performance issues relating to garbage collection or poor load balancing.

Compatibility with the old-time package for the "new" time package.

A parser and renderer for binary Olson timezone files whose format is specified by the tzfile(5) man page on Unix-like systems.

This package endows Data.Time, from the time package, with several data types and functions for enhanced processing of timezones.
