Haskell Weekly News
Issue 116 - May 02, 2009
Welcome to issue 116 of HWN, a newsletter covering developments in the
GHC 6.10.3 prerelease. Ian Lynagh announced a prerelease
version of GHC 6.10.3. There have been very few changes relative
to 6.10.2. Unless any major problems are uncovered, the final release
is expected to be built in a couple of days.
graphviz-2009.5.1. Ivan Lazar Miljenovic announced version 2009.5.1
of the graphviz library, which provides a Haskell interface to the
GraphViz program. Major changes include support for polyparse >=
1.1, dependency on GHC 6.10.*, functions from the Graphalyze
library, and more.
priority-sync-0.1.0.1: Cooperative task prioritization.. Christopher
Lane Hinson announced the release of the priority-sync package
for cooperative task prioritization.
HaL4: Local Haskell meeting, Halle/Saale, Germany, June 12. Henning
Thielemann requested proposals for talks for HaL4, a local
Haskell meeting in Halle, Germany on June 12.
TraverseAccum: an effectful accumulating map.. Florent Balestrieri
posted some code implementing an effectful accumulating map.
LondonHUG talk: Engineering Large Projects in Haskell. Don Stewart
posted slides from last week's London HUG talk, which
attempts to document some of the tips and tricks Galois has accumulated
using Haskell commercially for the past 10 years.
atom-0.0.2. Tom Hawkins announced the release of atom, a
Haskell DSL for designed hard realtime embedded programs. Eaton is
using it to control hydraulic hybrid refuse trucks and shuttle buses.
Bamse-0.9.4, a Windows Installer generator. Sigbjorn Finne
announced a new version of Bamse, a package and application for
letting you quickly put together Windows Installers for your software
projects/products from within the comforts of Haskell. New in this
release is the support for generating MSIs from your Cabal projects,
having them either be built from source or just have them be installed
and registered at install-time.
Dutch Haskell Users' Group (first meeting: May 6th). Chris Eidhof
announced the first meeting of the newly formed Dutch Haskell
Users' Group (DHUG), on May 6th at 19:30 in Utrecht.
Haskell Symposium Submission site now open. Stephanie Weirich
announced that submission to the Haskell Symposium is now open.
The submission deadline is May 8.
OpenGL, GLUT, OpenAL, and ALUT updates. Sven Panne announced
new bugfix releases for the OpenGL, GLUT,
OpenAL, and ALUT packages.
control-monad-exception-0.1: Explicitly typed exceptions. Pepe Iborra
announced the control-monad-exception package, which provides
explicitly typed exceptions for Haskell. The type of a computation in
the EM monad carries a list of the exceptions that the computation may
throw. A exception is raised with 'throw', which in addition adds it to
the type, and captured with 'catch', which correspondingly removes it
from the type. Only safe computations (all exceptions handled) can
escape from the monad.
Haskell File Manager. Michael Dever announced the first release of
Haskell File Manager, a program for viewing/managing the files on
your computer. It has all the common functionality you would expect
from your current file manager, copying, moving, deleting, renaming,
opening and searching.
uu-parsinglib-2.0.0. S. Doaitse Swierstra announced the release of
uu-parsinglib, the first version of the new parsing combinator
library package from Utrecht University. Features include online result
construction, much simpler internals than the combinators in the uulib
package, error correction, parsing ambiguous grammars, a monadic
interface, and more.
Takusen 0.8.4. Alistair Bayley announced version 0.8.4 of
Takusen, a database package; this is mostly a "get it working with
Google SoC: Space profiling reloaded. Patai Gergely asked for ideas
on his Google Summer of Code project to improve the Haskell space
