This package provides a Conduit interface for the LZMA compression algorithm used in the .xz file format.

Lifted-base exports IO operations from the base library lifted to any instance of MonadBase or MonadBaseControl. Note that not all modules from base are converted yet. The package includes a copy of the monad-peel test suite written by Anders Kaseorg.

This package provides a Haskell library including a Storable instance for Complex which is binary compatible with C99, C++ and Fortran complex data types.

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

This Haskell package uses a monad transformer approach for logging.

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

Special values are provided by a SpecialValues typeclass. Those can be used for example by QuickCheck, see quickcheck-special.

The zip-archive library provides functions for creating, modifying, and extracting files from zip archives in Haskell.

A cross-platform library with functions for adjusting code pages on Windows. On all other operating systems, the library does nothing.

This library provides Control.Lens. The combinators in Control.Lens provide a highly generic toolbox for composing families of getters, folds, isomorphisms, traversals, setters and lenses and their indexed variants.

Provides generalisations of swap :: (a,b) -> (b,a) and assoc :: ((a,b),c) -> (a,(b,c)) to Bifunctors supporting similar operations (e.g. Either, These).

This package provides a pretty printing class similar to Show, based on the HughesPJ pretty printing library. It provides the pretty printing class and instances for the Prelude types.

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

This package provides a simple wrapper to show the used CPU time of monadic computation with an IO base.

This package defines a class for types with default values.

This package provides semigroups for Haskell. In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation. A semigroup generalizes a monoid in that there might not exist an identity element. It also (originally) generalized a group (a monoid with all inverses) to a type where every element did not have to have an inverse, thus the name semigroup.

This package provides a simple (but internally ugly) memoization function.

Text.Regex.Base provides the interface API for regex-posix, regex-pcre, regex-parsec, regex-tdfa, regex-dfa.

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

Brick helps you write terminal user interfaces (TUIs). You write an event handler and a drawing function and the library does the rest.

This library provides a wrapper to mmap, allowing files or devices to be lazily loaded into memory as strict or lazy ByteStrings, ForeignPtrs or plain Ptrs, using the virtual memory subsystem to do on-demand loading.

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.

The YAML 1.2 format provides a much richer data-model and feature-set than the JavaScript Object Notation format. However, sometimes it's desirable to ignore the extra capabilities and treat YAML as if it was merely a more convenient markup format for humans to write JSON data. To this end this module provides a compatibility layer atop ghc-hsyaml ,which allows decoding YAML documents in the more limited JSON data-model while also providing convenience by reusing ghc-aeson's FromJSON instances for decoding the YAML data into native Haskell data types.

This library provides functions for parsing and pretty printing Roman numerals. Because the notation of Roman numerals has varied through the centuries this package allows for some customisation using a configuration that is passed to the conversion functions.

This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible. The library exposes a van Laarhoven interface. For an alternative interface, supporting an opaque optic type, see generic-optics.
