Regular, shape-polymorphic, parallel arrays now in AUR

Repa, a new library for multi-dimensional automatically-parallel arrays in Haskell, is now available in Arch Linux via AUR.  Such arrays may be converted to and from bytestrings, and written out in various formats. Example algorithms are available, including fft2d, matmult, and laplace, along with an algorithm library. The library may prove useful for scientific and numerical computing, where high level languages, with good parallel performance, should shine.

More information about Repa is available:

• In the release announcement
• In the accompanying ICFP paper.
• And in the haddock documentation.

The full set of packages are available in AUR:

• haskell-repa
• haskell-repa-io
• haskell-repa-bytestring
• haskell-repa-algorithms
• repa-examples

Arch Haskell News: Feb 16 2009

A regular update of Haskell in Arch Linux

Arch now has 926 Haskell packages in AUR.

That’s an increase of 27 new packages in the last 8 days, or 3.38 new Haskell apps a day. Well done everyone!

Noteworthy updates

• The functional reactive grapefruit gui library supported
  
• haskelldb suite now supported
• gtk2hs 0.10 now in [community]
  

Installing Packages from AUR

To install AUR packages, we recommend yaourt, as in:

yaourt --noconfirm  --lightbg --aur -S haskell-haha

You may want to alias that command line. Here’s an example from this week’s releases:

The reason to use yaourt over cabal-install is that AUR packages correctly resolve all versions and, more importantly, C library and other system dependencies. Packages will also be pulled from the binary releases in [extra] and [community] where available, saving you build times.
