Haskell Weekly News: December 06, 2008

Welcome to issue 96 of HWN, a newsletter covering developments in the Haskell community.

Announcements

Haskell haikus. Gwern Branwen announced that he has collected all known haikus about Haskell and put them on a wiki page. Add more!

Platforms that GHC supports. Simon Peyton-Jones linked to a new page clearly articulating what platforms GHC supports, and what platforms its maintainers would like it to support. If you're interested and willing to help sponsor a "Tier 2" platform, let them know!

Using Data Parallel Haskell. Manuel Chakravarty announced a new wiki page with documentation for Data Parallel Haskell.

DrHylo 0.0.1. Hugo Pacheco announced the release of DrHylo, a tool for deriving hylomorphisms from a restricted Haskell syntax. It is based on the algorithm first presented in the paper Deriving Structural Hylomorphisms From Recursive Definitions at ICFP'96 by Hu, Iwasaki, and Takeichi. The generated code can be run with Pointless Haskell, allowing the visualization of the recursion trees of Haskell functions.

pointless-haskell 0.0.1. Hugo Pacheco announced the release of Pointless Haskell, a library for point-free programming with recursion patterns defined as hylomorphisms, inspired in ideas from the PolyP library. The re-implementation of the library using type functions (in opposition to classes with functional dependencies) enables a type-level view of data types as the fixed points of functors and provides a better experience to the users in terms of code sanity. The library also features the visualization of the intermediate data structure of hylomorphisms with GHood.

Projects that depend on the vty package?. Corey O'Connor asked whether there are any other projects that depend on the vty package. If so, let him know! The package also has a new trac and wiki.

haskell-src-exts 0.4.4. Niklas Broberg announced the release of haskell-src-exts 0.4.4, which adds support for pragmas.

ChristmasTree 0.1. S. Doaitse Swierstra announced the release of the ChristmasTree package, which stands for "Changing Haskell's Read Implementation Such That by Manipulating Abstract Syntax Trees it Reads Expressions Efficiently".

TTTAS. S. Doaitse Swierstra announced the release of TTTAS, a library for typed transformations of typed abstract syntax.

GHood. Hugo Pacheco announced that GHood, a graphical backend for the lightweight Hood Haskell debugger, has now been released as a Cabal package.

Discussion

Animated line art. Andrew Coppin asked for ideas on writing Haskell to generate some animations.

Jobs

Scala job in Boston writing quantitative finance software. Paul Chiusano announced that ClariFI is looking to hire developers with a strong background in functional programming to do a mixture of Scala and Java programming. ClariFI is a small company (about 15 developers) that specializes in software for quantitative investment management. This position is for the Boston office. If you're interested, send him an email.

Blog noise

Haskell news from the blogosphere.
