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

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 package contains basic primitives for the Foundation set of packages.

This package contains a wrapped name module for TimeLocale.

MissingH is a library of all sorts of utility functions for Haskell programmers. It is written in pure Haskell and thus should be extremely portable and easy to use.

This package provides Haskell modules to allow use of Accessor to access state in transformers State monad.

This package provides access to ALSA infrastructure, that is needed by both alsa-seq and alsa-pcm.

This package contains the C sources of LPeg, as well as some tiny Haskell helper to load the package. . <http://www.inf.puc-rio.br/~roberto/lpeg/>

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

The functional graph library, FGL, is a collection of type and function definitions to address graph problems. The basis of the library is an inductive definition of graphs in the style of algebraic data types that encourages inductive, recursive definitions of graph algorithms.

SDL_image is an image file loading library. It loads images as SDL surfaces, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, XCF, XPM, XV.

This package provides a backwards compatibility layer for Template Haskell newer than 2.8.

This library provides minimal Haskell binding to libxml2.

Compatibility layer for Data.Array.Byte providing boxed wrappers for ByteArray and MutableByteArray and relevant instances for GHC < 9.4.

This Haskell package was originally present in classy-prelude.

th-reify-many provides functions for recursively reifying top level declarations. The main intended use case is for enumerating the names of datatypes reachable from an initial datatype, and passing these names to some function which generates instances.

This package exposes combinators that can wrap arbitrary monadic actions. They run the action and potentially retry running it with some configurable delay for a configurable number of times. The purpose is to make it easier to work with IO and especially network IO actions that often experience temporary failure and warrant retrying of the original action. For example, a database query may time out for a while, in which case we should hang back for a bit and retry the query instead of simply raising an exception.

This package provides instances defined in later versions of ghc-binary package.

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.

Per Conor McBride, the Newtype typeclass represents the packing and unpacking of a newtype, and allows you to operate under that newtype with functions such as ala'.

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.

This package makes it possible to define schemas for use when loading configuration files using the config-value format. These schemas can be used to process a configuration file into a Haskell value or to automatically generate documentation for the file format.

The texmath library provides functions to read and write TeX math, presentation MathML, and OMML (Office Math Markup Language, used in Microsoft Office). Support is also included for converting math formats to pandoc's native format (allowing conversion, via pandoc, to a variety of different markup formats). The TeX reader supports basic LaTeX and AMS extensions, and it can parse and apply LaTeX macros.

This package provides a compatibility layer for using GHC call stacks with different versions of the compiler.
