This package provides an implementation of the standard diff algorithm, and utilities for pretty printing.

This package provides functionality for generalising the deriving mechanism in Haskell to arbitrary classes.

Prior to base-4.7.0.0 there was no Eq instance for ErrorCall. This package provides an orphan instance.

GHC 7.4 gave us the ability to talk about ConstraintKinds. They stopped crashing the compiler in GHC 7.6. This package provides a vocabulary for working with them.

This library provides some useful tools from the C standard library.

A package for convenient access to high-resolution clock and timer functions of different operating systems via a unified API.

Please see the README and documentation at <https://www.stackage.org/package/githash>

This library contains scalable timer functions provided by a timer manager.

This is a simple time library providing a simple but powerful and performant API. The backbone of the library are the Timeable and Time type classes. Each Timeable instances can be converted to a type that has a Time instances, and thus are different representations of current time.

GLib is a collection of C data structures and utility functions for the GObject system, main loop implementation, for strings and common data structures dealing with Unicode. This package only binds as much functionality as required to support the packages that wrap libraries that are themselves based on GLib.

This package contains helper functions on top of Template Haskell.

For example, functionExtractor extracts all functions after a regexp-pattern, which can be useful if you wish to extract all functions beginning with test (for a test framework) or all functions beginning with wc (for a web service).

This package provides Unix terminal support for Vty.

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.

This package provides a UTF-8 aware subset of Lua's string module for Haskell. The functions provided by this module are upper, lower, len, reverse, and sub.

This Haskell package provides some useful control operators for looping.

The Par monad offers an API for parallel programming. The library works for parallelising both pure and IO computations, although only the pure version is deterministic. The default implementation provides a work-stealing scheduler and supports forking tasks that are much lighter weight than IO-threads.

This package provides a simple type class for converting values of different string types into values of other string types.

This package provides combinators for building fast hashing functions. It includes hashing functions for all basic Haskell98 types.

This package defines classes of monads that can perform multiple executions in parallel and combine their results. For any monad that's an instance of the class, the package re-implements a subset of the Control.Monad interface, but with parallel execution.

This library provides functions for use in parsing indentation sensitive contexts. It parses blocks of lines all indented to the same level as well as lines continued at an indented level below.

This library is simply a collection of linear-algebra related modules split from the statistics library.

This package is a Haskell library for the representation, parsing, and pretty-printing of GLSL 1.50 code.

The major use of These of this is provided by the align member of Semialign class, representing a generalized notion of "zipping with padding" that combines structures without truncating to the size of the smaller input. It turns out that zip operation fits well the Semialign class, forming lattice-like structure.

This module defines the Pandoc data structure, which is used by pandoc to represent structured documents. It also provides functions for building up, manipulating and serialising Pandoc structures.
