--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20090512 Issue 117 - May 12, 2009 --------------------------------------------------------------------------- Welcome to issue 117 of HWN, a newsletter covering developments in the [1]Haskell community. The Haskell Platform is here! Announcements The Haskell Platform. Don Stewart [2]announced the first release of the [3]Haskell Platform: a single, standard Haskell distribution for every system. The Haskell Platform is a blessed library and tool suite for Haskell culled from Hackage, along with installers for a wide variety of systems. It saves developers work picking and choosing the best Haskell libraries and tools to use for a task. GHC version 6.10.3. Ian Lynagh [4]announced the release of [5]GHC 6.10.3. This release contains a handful of bugfixes relative to 6.10.2 and better line editing support in GHCi, so updating is recommend. See the [6]release notes for more details. Bindings for libguestfs. Richard W.M. Jones [7]announced some [8]partial bindings for [9]libguestfs. Heads up: Conflicting versions of network-2.2.1. Johan Tibell [10]announced a heads-up that the version of network-2.2.1 that shipped with GHC 6.10 differs from the one on Hackage. If you want the API additions that are present in network-2.2.1 on Hackage, be sure to use network-2.2.1.1 instead. hpc-strobe-0.1: Hpc-generated strobes for a running Haskell program. Thorkil Naur [11]announced the initial release of [12]hpc-strobe, a rudimentary library that demonstrates the possibility of using Hpc (Haskell Program Coverage) to inspect the state of a running Haskell program. hpc-strobe uses the basic machinery provided by Hpc to produce multiple tix files, also called strobes, representing the coverage at different times while the program is running. By subtracting such two tix files, again using Hpc machinery, a tix file representing the expressions used between the times of recording the subtracted tix files is produced. This may be used, for example, to get a better idea of what a long-running program is doing. It could also be used as a profiling tool, getting information about how many times individual expressions are used. BUG FIX release of regex-tdfa-1.1.2. ChrisK [13]announced version 1.1.2 of [14]regex-tdfa, a bug-fix release. Silkworm game. Duane Johnson [15]announced the release of [16]Silkworm, a game written in Haskell using [17]Hipmunk and GLFW. Discussion Platform policy question: API compatibility in minor releases. Duncan Coutts began a [18]discussion on versioning policies for major and minor releases, for packages included in the Haskell Platform. See also the [19]newly started discussion on the purpose of Haskell Platform releases. Blog noise [20]Haskell news from the [21]blogosphere.

Quotes of the Week * jfredett: My haskell-spider senses were tingling, I just overshot RT and went for the Halting Problem. * NeilBrown: I heard that if you chant "I don't think this can be done in Haskell" three times in front of a text editor, Don Stewart appears and implements it in one line... * bos: The last couple of times I've wanted a book like that, I wrote the book myself. It's a very effective way to get the book you want, compared to wishing. * edwardk: {-# LANGUAGE time to pay the cutting edge typing features tax #-} * SPJ: Haha this is good news, I have slipped functional programming into your brain without you realising it is something very weird. * EvilTerran: writing machine code by hand on tape with a magnetised needle looks good compared to PHP :P * Athas: I like Lisp for its extreme expressivity, but I think it's easier to make Haskell more powerful, than to make Lisp more statically safe. * roconnor: I can't wait for the Density Comonad chapter of "learn you a haskell" About the Haskell Weekly News New editions are posted to [47]the Haskell mailing list as well as to [48]the Haskell Sequence and [49]Planet Haskell.
