This package provides a practical incremental and one-pass, pure API to the <https://en.wikipedia.org/wiki/SHA-1 SHA-1 hash algorithm> (including <https://en.wikipedia.org/wiki/HMAC HMAC> support) with performance close to the fastest implementations available in other languages. . The implementation is made in C with a haskell FFI wrapper that hides the C implementation. . NOTE: This package has been forked off @cryptohash-0.11.7@ because the @cryptohash@ package has been deprecated and so this package continues to satisfy the need for a lightweight package providing the SHA1 hash algorithm without any dependencies on packages other than @base@ and @bytestring@. . Consequently, this package can be used as a drop-in replacement for @cryptohash@'s "Crypto.Hash.SHA1" module, though with a clearly smaller footprint.

This library provides an extensible interface for interacting with SMT solvers using SMT-LIB. The smtlib-backends-process package provides a backend that runs solvers as external processes, and the smtlib-backends-z3 package provides a backend that uses inlined calls to Z3's C API.

@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 library allows an application to extend the 'global state' hidden inside the IO monad with semi-arbitrary data. Data is required to be 'Typeable'. The library provides an essentially unbounded number of key-value stores indexed by strings, with each key within the stores also being a string.

Haskell bindings for libarchive. Provides the ability to unpack archives, including the ability to unpack archives lazily.

This is an industrial-strength monadic parser combinator library. Megaparsec is a feature-rich package that tries to find a nice balance between speed, flexibility, and quality of parse errors.

This library contains glue code used to interconnect Haskell GI and Cairo

This package exposes internal types and functions that can be used to extend Hspec's functionality.

This library provides tools for reading and manipulating the .cabal file format.

C-structs lets you create correct C structs in Haskell. These can be used for FFI calls, import as well as exports. This package is part of the development efforts for the Python library Pythas. Pythas provides an interface to import Haskell modules. . Note: As of GHC 9.2 structs cannot be passed by value, only by reference.

GHC package that provides types that when used in a package can be identified by the <https://hackage.haskell.org/package/fusion-plugin fusion-plugin> package to perform any extra optimizations.

This library provides an interface to portably work with byte arrays whose contents are known to be of a fixed endianness. There are two ways to use this module. See the `System.ByteOrder` module for more documentation.

Bindings for Atk, autogenerated by haskell-gi.

Included are some folds and maps I've found useful in parsing XML data.

Bindings for Graphene, autogenerated by haskell-gi.

Replacement for [composition](hackage.haskell.org/package/composition) or [composition-extra](hackage.haskell.org/package/composition-extra), exporting everything in one module.

In many cases, it is useful, necessary, or simply nice to limit how frequently you perform some action. For example, you may want to limit how often your program makes a request of some web site. This library is intended as a general-purpose mechanism for rate-limiting IO actions.

Haskell bindings for libarchive. Provides the ability to unpack archives, including the ability to unpack archives lazily.

Bindings for Gtk, autogenerated by haskell-gi.

As of 2023, this library is largely obsolete: arbitrary test generators with shrinking such as [falsify](https://hackage.haskell.org/package/falsify) offer much better user experience. . SmallCheck is a testing library that allows to verify properties for all test cases up to some depth. The test cases are generated automatically by SmallCheck.

This library implements an SMT-LIB backend (in the sense of the smtlib-backends package) which runs solvers as external processes.

This package adds resource management and exception handling to the @pipes@ ecosystem. . Notable features include: . * /Resource Safety/: Guarantee finalization using @finally@, @bracket@ and more . * /Exception Safety/: Even against asynchronous exceptions! . * /Laziness/: Only acquire resources when you need them . * /Promptness/: Finalize resources early when you are done with them . * /Native Exception Handling/: Catch and resume from exceptions inside pipes . * /No Buy-in/: Mix resource-safe pipes with unmanaged pipes using @hoist@.

This package provides a stable version of Hspec which is used to test the in-development version of Hspec.
