Provides Arbitrary instances for fgl graphs to avoid adding a QuickCheck dependency for fgl whilst still making the instances available to others. Also available are non-fgl-specific functions for generating graph-like data structures.

This is library provides utility to use Netlink from Haskell. The scope of this package extends over general Netlink support to specific implementations of Netlink families.

The config-ini Haskell library exports some simple monadic functions to ease the parsing of .ini-style configuration files, and to write and update them in an efficient diff-minimal way. This means that if you parse a file, update a single field, and reserialize, that file should differ only in the field we changed and that's it: field order, comments, and incidental whitespace will remain unchanged. The library aims to produce human-readable error messages when things go wrong.

Efficient hashing-based container types. The containers have been optimized for performance critical use, both in terms of large data quantities and high speed.

Long lived application data typically should not contain any thunks. This library can be used to examine values for unexpected thunks, which can then be used in assertions. This can be invaluable in avoiding memory leaks, or tracking down existing ones.

This module provides set and multiset operations on ordered lists.

A parser and renderer for binary Olson timezone files whose format is specified by the tzfile(5) man page on Unix-like systems. For more information about this format, see http://www.iana.org/time-zones/repository/tz-link.html. Functions are provided for converting the parsed data into TimeZoneSeries objects from the timezone-series package.

Network.HostName is a simple package providing a means to determine the hostname.

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

Convenience functions and TH for working with constraints. See README.md for example usage.

This package provides a plugin that allows you to set breakpoints for debugging purposes. See the [README](https://github.com/aaronallen8455/breakpoint#breakpoint) for details.

The doctest program checks examples in source code comments. It is modeled after doctest for Python (<https://docs.python.org/3/library/doctest.html>). . Documentation is at <https://github.com/martijnbastiaan/doctest-parallel#readme>.

This Haskell package provides Monomorphic variants of the Functor, Foldable, and Traversable typeclasses. If you understand Haskell's basic typeclasses, you understand mono-traversable. In addition to what you are used to, it adds on an IsSequence typeclass and has code for marking data structures as non-empty.

This library provides fast parsing and formatting utilities for Unix time in Haskell.

This package provides Haskell library for matching files using patterns such as \"src\/**\/*.png\" for all @file.png files recursively under the @filesrc directory.

Some of its features include:

• All matching is O(n).

• Most functions pre-compute some information given only one argument.

• Uses match and substitute to extract suitable strings from the * and ** matches, and substitutes them back into other patterns.

• Uses step and matchMany to perform bulk matching of many patterns against many paths simultaneously.

• Uses System.FilePattern.Directory to perform optimised directory traverals using patterns.

This package provides optimized functions to determine the edit distances for fuzzy matching, including Levenshtein and restricted Damerau-Levenshtein algorithms.

This haskell library provides validity and validity-based testing for ghc-hspec.

Provides default instances for types from the dlist package.

This package provides a dependent sum is a generalization of a particular way of thinking about the Either type. Either a b can be thought of as a 2-tuple (tag, value), where the value of the tag determines the type of the value. In particular, either tag = Left and value :: a or tag = Right and value :: b. This package allows you to define your own dependent sum types by using your own "tag" types.

This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the zlib C library so it has high performance. It supports the zlib, gzip and raw compression formats. It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full zlib feature set.

Lua module wrapping Text.DocLayout.

This Haskell package uses a monad transformer approach for logging.

This package provides Template Haskell functions for determining source code locations of messages.

This package provides types and combinators for linear algebra on free vector spaces.

This package provides a generic interface for multiple Vty platforms in one package so you don't have to conditionally depend on them in your cabal file.
