Haskell Weekly News
Issue 119 - May 23, 2009
Welcome to issue 119 of HWN, a newsletter covering developments in the
GHC porting works again. Ian Lynagh announced that the
instructions for porting GHC to a new architecture now work again
with the HEAD. If you get stuck when trying to do a port, feel free to
ask on cvs-ghc at haskell.org or in #ghc on freenode.
6.10.4 plans. Ian Lynagh announced plans for a 6.10.4 bugfix release
of GHC. If you know of any bugs that you think should be looked into
for 6.10.4, please let the development team know.
The Timber compiler 1.0.3. Johan Nordlander announced the release of
version 1.0.3 of the Timber compiler. Timber is a modern language for
building event-driven systems, based around the notion of reactive
objects. It is also a purely functional language derived from Haskell,
although with a strict evaluation semantics. 1.0.3 is a bug fix
release, paving the way for future feature releases.
mathlink-220.127.116.11. Tracy Wadleigh announced the release of
mathlink, a library for writing Mathematica packages in Haskell. One
simply writes some functions of type (MLGet a, MLPut b) => a -> IO b
and provides a package specification in a simple DSL; the result is a
program that exposes functions that can be called from Mathematica.
text 0.2, fast and comprehensive Unicode support using stream fusion.
Bryan O'Sullivan announced the availability of text 0.2, an
efficient Unicode text library that uses stream fusion. New and notable
in this release is support for lazy, chunked text, so you can process
text files far larger than memory using a small footprint.
Haskell Hackathon in Philadelphia. Brent Yorgey announced Hac phi,
a Haskell hackathon to be held in Philadelphia in July. Check out the
wiki page and add your name if you are interested in attending!
More details to follow soon.
feed2twitter 0.2 & hackage2twitter 0.2.1. Tom Lokhorst announced
the first release of feed2twitter, a library for sending posts from
a news feed to Twitter.
EsotericBot 0.0.1. spoon announced the release of Esotericbot,
a sophisticated, lightweight IRC bot, written in Haskell.
atom 0.0.4. Tom Hawkins announced a new release of atom; this
version adds an array datatype (A a).
Hieroglyph-2.21 and buster, buster-gtk, and buster-network-2.0. Jeff
Heard announced new releases of Hieroglyph, buster,
buster-gtk, and buster-network, with tons of changes; read
Jeff's original announcement for details.
TxtSushi 0.1. Keith Sheppard announced the first version of
TxtSushi, a collection of command line utilities for processing
tab-delimited and CSV files. It includes a utility for doing SQL
SELECTs on flat files.
Should exhaustiveness testing be on by default? Don Stewart started a
discussion, prompted by a recent blog post, on whether coverage
checking should be on by default, and other issues relating to compiler
warnings and coding style.
Proposal on the platform API policy question. Duncan Coutts
proposed a general policy for Haskell Platform release cycles and
versioning, based on input from previous discussions.
the problem of design by negation. Michael Mossey began a
discussion on software design philosophies. "Design by negation"
Haskell in 3 Slides. John Van Enk asked for ideas on a 3 to 4 slide
introduction to Haskell. What do YOU think should be on those slides?
