ghc-hex 0.2.0
Channel: guix
Location: gnu/packages/haskell-xyz.scm (gnu packages haskell-xyz)

Licenses: Modified BSD
Build system: haskell
Synopsis: Convert strings into hexadecimal and back
Description:

This package converts between bytestrings and their hexadecimal string representation.

ghc-psqueues 0.2.7.3
Dependencies: ghc-hashable@1.4.2.0
Channel: guix
Location: gnu/packages/haskell-xyz.scm (gnu packages haskell-xyz)
Home page: https://hackage.haskell.org/package/psqueues
Licenses: Modified BSD
Build system: haskell
Synopsis: Pure priority search queues
Description:

The psqueues package provides Priority Search Queues in three different flavors:

  • OrdPSQ k p v, which uses the Ord k instance to provide fast insertion, deletion and lookup. This implementation is based on Ralf Hinze's A Simple Implementation Technique for Priority Search Queues.

    Hence, it is similar to the PSQueue library, although it is considerably faster and provides a slightly different API.

  • IntPSQ p v is a far more efficient implementation. It fixes the key type to Int and uses a https://en.wikipedia.org/wiki/Radix_tree, radix tree (like IntMap) with an additional min-heap property.

  • HashPSQ k p v is a fairly straightforward extension of IntPSQ: it simply uses the keys' hashes as indices in the IntPSQ. If there are any hash collisions, it uses an OrdPSQ to resolve those. The performance of this implementation is comparable to that of IntPSQ, but it is more widely applicable since the keys are not restricted to Int, but rather to any Hashable datatype.

Each of the three implementations provides the same API, so they can be used interchangeably.

Typical applications of Priority Search Queues include:

  • Caches, and more specifically LRU Caches;

  • Schedulers;

  • Pathfinding algorithms, such as Dijkstra's and A*.

ghc-base-prelude 1.6.1
Channel: guix
Location: gnu/packages/haskell-xyz.scm (gnu packages haskell-xyz)
Home page: https://github.com/nikita-volkov/base-prelude
Licenses: Expat
Build system: haskell
Synopsis: The most complete prelude formed solely from the Haskell's base package
Description:

This Haskell package aims to reexport all the non-conflicting and most general definitions from the "base" package.

This includes APIs for applicatives, arrows, monoids, foldables, traversables, exceptions, generics, ST, MVars and STM.

This package will never have any dependencies other than "base".

Versioning policy:

The versioning policy of this package deviates from PVP in the sense that its exports in part are transitively determined by the version of "base". Therefore it's recommended for the users of ghc-base-prelude to specify the bounds of "base" as well.

Synopsis: Higher-order functional reactive programming
Description:

This library lets you write interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse. Reflex is a fully-deterministic, higher-order FRP interface and an engine that efficiently implements that interface.

ghc-transformers 0.5.6.2
Channel: guix
Location: gnu/packages/haskell-xyz.scm (gnu packages haskell-xyz)
Home page: https://hackage.haskell.org/package/transformers
Licenses: Modified BSD
Build system: haskell
Synopsis: Concrete functor and monad transformers
Description:

Transformers provides functor and monad transformers, inspired by the paper "Functional Programming with Overloading and Higher-Order Polymorphism", by Mark P Jones, in Advanced School of Functional Programming, 1995 http://web.cecs.pdx.edu/~mpj/pubs/springschool.html.

This package contains:

  • the monad transformer class (in Control.Monad.Trans.Class)

  • concrete functor and monad transformers, each with associated operations and functions to lift operations associated with other transformers.

This package can be used on its own in portable Haskell code, in which case operations need to be manually lifted through transformer stacks (see Control.Monad.Trans.Class for some examples). Alternatively, it can be used with the non-portable monad classes in the mtl or monads-tf packages, which automatically lift operations introduced by monad transformers through other transformers.

ghc-splitmix 0.1.0.4
Channel: guix
Location: gnu/packages/haskell-xyz.scm (gnu packages haskell-xyz)
Home page: https://hackage.haskell.org/package/splitmix
Licenses: Modified BSD
Build system: haskell
Synopsis: Fast and splittable pseudorandom number generator
Description:

This package provides a Pure Haskell implementation of the SplitMix pseudorandom number generator. SplitMix is a "splittable" pseudorandom number generator that is quite fast: 9 64-bit arithmetic/logical operations per 64 bits generated. SplitMix is tested with two standard statistical test suites (DieHarder and TestU01, this implementation only using the former) and it appears to be adequate for "everyday" use, such as Monte Carlo algorithms and randomized data structures where speed is important. In particular, it should not be used for cryptographic or security applications, because generated sequences of pseudorandom values are too predictable (the mixing functions are easily inverted, and two successive outputs suffice to reconstruct the internal state).
