vec-0.2: vec.cabal

cabal-version:      >=1.10
name:               vec
version:            0.2
synopsis:           Vec: length-indexed (sized) list
category:           Data, Dependent Types
description:
  This package provides length-indexed (sized) lists, also known as vectors.
  .
  @
  data Vec n a where
  \    VNil  :: Vec 'Nat.Z a
  \    (:::) :: a -> Vec n a -> Vec ('Nat.S n) a
  @
  .
  The functions are implemented in four flavours:
  .
  * __naive__: with explicit recursion. It's simple, constraint-less, yet slow.
  .
  * __pull__: using @Fin n -> a@ representation, which fuses well,
  but makes some programs hard to write. And
  .
  * __data-family__: which allows lazy pattern matching
  .
  * __inline__: which exploits how GHC dictionary inlining works, unrolling
  recursion if the size of 'Vec' is known statically.
  .
  As best approach depends on the application, @vec@ doesn't do any magic
  transformation. Benchmark your code.
  .
  This package uses [fin](https://hackage.haskell.org/package/fin), i.e. not @GHC.TypeLits@, for indexes.

  === Similar packages
  .
  * [linear](https://hackage.haskell.org/package/linear) has 'V' type,
  which uses 'Vector' from @vector@ package as backing store.
  @Vec@ is a real GADT, but tries to provide as many useful instances (upto @lens@).
  .
  * [vector-sized](https://hackage.haskell.org/package/vector-sized)
  Great package using @GHC.TypeLits@. Current version (0.6.1.0) uses
  @finite-typelits@ and @Int@ indexes.
  .
  * [sized-vector](https://hackage.haskell.org/package/sized-vector) depends
  on @singletons@ package. @vec@ isn't light on dependencies either,
  but try to provide wide GHC support.
  .
  * [fixed-vector](https://hackage.haskell.org/package/fixed-vector)
  .
  * [sized](https://hackage.haskell.org/package/sized) also depends
  on a @singletons@ package. The @Sized f n a@ type is generalisation of
  @linear@'s @V@ for any @ListLike@.
  .
  * [clash-prelude](https://hackage.haskell.org/package/clash-prelude)
  is a kitchen sink package, which has @CLaSH.Sized.Vector@ module.
  Also depends on @singletons@.
