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 functions for signed 15.16 precision fixed point arithmetic.

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

This package provides Haskell bindings to bzlib and Conduit support for streaming compression and decompression.

This package provides memory abstractions, such as chunk of memory, polymorphic byte array management and manipulation functions. It contains a polymorphic byte array abstraction and functions similar to strict ByteString, different type of byte array abstraction, raw memory IO operations (memory set, memory copy, ..) and more

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

This library defines an existential type Some'. . @ data Some f where \ Some :: f a -> Some f @ . in few variants, and utilities to work with it. . If you are unsure which variant to use, use the one in "Data.Some" module.

C->Haskell assists in the development of Haskell bindings to C libraries. It extracts interface information from C header files and generates Haskell code with foreign imports and marshaling. Unlike writing foreign imports by hand (or using hsc2hs), this ensures that C functions are imported with the correct Haskell types.

This library provides parsers and printers for bencoded data. Bencode is the encoding used by the peer-to-peer file sharing system BitTorrent for storing and transmitting loosely structured data.

This package is a compatibility package for a singleton data type . > data Solo a = Solo a . Note: it's not a @newtype@ . @Solo@ is available in @base-4.16@ (GHC-9.2).

Provides default instances for types from the dlist package.

This package provides Haskell bindings for libcmark, the reference parser for CommonMark, a fully specified variant of Markdown. It includes bundled libcmark sources, and does not require prior installation of the C library.

Provides a small set of helper functions for testing Megaparsec parsers with Hspec.

This library is for working with \".tar\" archive files. It can read and write a range of common variations of the tar archive format including V7, POSIX USTAR and GNU formats. It provides support for packing and unpacking portable archives. This makes it suitable for distribution but not backup because details like file ownership and exact permissions are not preserved. It also provides features for random access to archive content using an index.

This library provides implementations of concurrent FIFO queues (for both general boxed and primitive unboxed values) that are fast, perform well under contention, and offer a Chan-like interface. The library may be of limited usefulness outside of x86 architectures where the fetch-and-add instruction is not available.

GNU ncurses is a library for creating command-line application with pseudo-graphical interfaces. This package is a nice, modern binding to GNU ncurses.

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.

This Haskell library provides a place for lots of orphan instances for the ghc-vector package.

This package endows Data.Time, from the time package, with several data types and functions for enhanced processing of timezones. For one way to create timezone series, see the ghc-timezone-olson package.

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

This package provides testing utilities that are useful in conjunction with the Validity typeclass.

This library provides tools to calculate various string metrics efficiently.

This package provides an URI manipulation interface. In network-2.6 the Network.URI module was split off from the network package into this package.
