Bindings for HarfBuzz, autogenerated by haskell-gi.

This package lacks a description. Run "info '(guix) Synopses and Descriptions'" for more information.

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.

This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the bz2 C library so it has high performance.

It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full bzip2 feature set.

Parser and writer for handling sectioned config files in Haskell. . The ConfigFile module works with configuration files in a standard format that is easy for the user to edit, easy for the programmer to work with, yet remains powerful and flexible. It is inspired by, and compatible with, Python's ConfigParser module. It uses files that resemble Windows .INI-style files, but with numerous improvements. . ConfigFile provides simple calls to both read and write config files. It's possible to make a config file parsable by this module, the Unix shell, and make.

@pipes-group@ uses @FreeT@ and lenses to group streams into sub-streams. Notable features include: . * /Perfect Streaming/: Group elements without collecting them into memory . * /Lens Support/: Use lenses to simplify many common operations . @Pipes.Group@ contains the full documentation for this library. . Read @Pipes.Group.Tutorial@ for an extensive tutorial.

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.

Bindings to libzfs, for dealing with the Z File System and Zpools.

Bindings for GdkX11, 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 package provides tests that can be used with any queue implementation that satisfies the `abstract-deque` interface.

Cabal with c2hs dependencies.

Bindings for JavaScriptCore 6.x, autogenerated by haskell-gi.

This package normalizes variations in the interface for inspecting datatype information via Template Haskell so that packages and support a single, easier to use informational datatype while supporting many versions of Template Haskell.

Derive Template Haskell's @Lift@ class for datatypes using @TemplateHaskell@. The functionality in this package has largely been subsumed by the @DeriveLift@ language extension, which is available in GHC 8.0 and later versions. As such, this package is only useful as a way to backport bugfixes to @DeriveLift@ in later GHC versions back to older GHCs. . The following libraries are related: . * The <https://hackage.haskell.org/package/th-orphans th-orphans> package provides instances for @template-haskell@ syntax types. . * The <http://hackage.haskell.org/package/th-lift-instances th-lift-instances> package provides @Lift@ instances for types in @base@, @text@, @bytestring@, @vector@, etc. Some of these instances are only provided for old versions of their respective libraries, as the same @Lift@ instances are also present upstream on newer versions.

Michael and Scott queues are described in their PODC 1996 paper: . <http://dl.acm.org/citation.cfm?id=248052.248106> . These are single-ended concurrent queues based on a singlly linked list and using atomic CAS instructions to swap the tail pointers. As a well-known efficient algorithm they became the basis for Java's @ConcurrentLinkedQueue@.

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 package provides a plugin to verify Haskell programs. But most likely you should be using the [liquidhaskell package](https://hackage.haskell.org/package/liquidhaskell) instead, which rexports this plugin together with necessary specifications for definitions in the boot libraries.

This package provides various primitive memory-related operations.

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