This library provides an easy way to define command line parsers.

This package provides portable implementations of parts of the unix package. This package re-exports the unix package when available. When it isn't available, portable implementations are used.

With this package you can build a Storable instance of a record type from Storable instances of its elements in an elegant way. It does not do any magic, just a bit arithmetic to compute the right offsets, that would be otherwise done manually or by a preprocessor like C2HS. There is no guarantee that the generated memory layout is compatible with that of a corresponding C struct. However, the module generates the smallest layout that is possible with respect to the alignment of the record elements.

This package provides a quasi-quoter for raw SQL for ghc-persistent.

Haskell library for parsing of ISO 8601 dates, originally from aeson.

This package provides a Readable type class for reading data types from ByteString and Text. It also includes efficient implementations for common data types.

This library provides everything that microlens provides plus instances to make each, at, and ix usable with arrays, ByteString, and containers. This package is a part of the microlens family; see the readme on Github.

This library provides Numeric.Interval.Interval, which represents a closed, convex set of floating point values.

This package provides two simple conduit wrappers around STM channels: a source and a sink.

This package provides portable implementations of parts of the unix package. This package re-exports the unix package when available. When it isn't available, portable implementations are used.

This library provides a type for specifying Optional function arguments.

This library encourages an error-handling style that directly uses the type system, rather than out-of-band exceptions.

This package supplements the Validity typeclass with standard properties for functions operating on them.

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 a parser and pretty printer for converting between Haskell values and JSON. JavaScript Object Notation is a lightweight data-interchange format.

ghc-doctest-driver-gen is a Doctest's driver file generator. It lets you automatically generate driver file for Doctest's Cabal integration.

This library provides an implementation of the older blaze-builder interface in terms of the new builder that shipped with bytestring-0.10.4.0. This implementation is mostly intended as a bridge to the new builder, so that code that uses the old interface can interoperate with code that uses the new implementation.

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 Haskell library provides utilities creating, comparing, parsing and printing Universally Unique Identifiers or UUIDs.

This Haskell library contains type definitions for Universally Unique Identifiers or UUIDs, and basic conversion functions.

Checkers wraps up the expected properties associated with various standard type classes as QuickCheck properties. It also provides some morphism properties, arbitrary instances, and generator combinators for common data types.

regex-applicative is a Haskell library for parsing using regular expressions. Parsers can be built using Applicative interface.

This package provides a fast, reliable priority queue implementation based on a binomial heap.

This Haskell package provides interfaces and helper functions for the ghc-persistent package.
