Haskell Weekly News
Issue 84 - September 06, 2008
Welcome to issue 84 of HWN, a newsletter covering developments in the
This is the "This issue is not late since the HWN will henceforth be
published on Saturday now that I have real work to do" edition.
Featured this week: darcs hacking sprint plans solidify, xmonad 0.8
released, typed sprintf and sscanf, and tons of discussion about
everything from functional references to splitting up the base library
to the future direction of Haskell.
unicode-properties 184.108.40.206, unicode-names 220.127.116.11. Ashley Yakeley
announced the release of the unicode-properties 18.104.22.168 and
unicode-names 22.214.171.124 packages, which are representations in
Haskell of various data in the Unicode 3.2.0 Character Database.
experimental static blog engine in Haskell. jinjing announced the
initial release of Panda, an experimental static blog engine written
darcs hacking sprint, venues confirmed! (25-26 October). Eric Y. Kow
announced that two venues (Brighton, UK and Portland, Oregon, USA)
have been confirmed for the darcs hacking sprint on 25-26 October.
darcs weekly news #2. Eric Y. Kow The second weekly issue of the
darcs weekly news has been published.
xmonad 0.8 released!. Don Stewart announced the release of
xmonad 0.8, featuring a general purpose "gaps" replacement, locale
support, the ability to create your own configuration parsers, and
various other enhancements and fixes.
POPL logo design contest. Don Stewart forwarded a message
announcing a logo design contest for POPL 2009. Dust off your magic
markers/photoshop skills and get designing!
ICFP09 Announcement. Matthew Fluet announced ICFP 2009, to be
held 31st August to 2nd September 2009 in Edinburgh. ICFP provides a
forum for researchers and developers to hear about the latest work on
the design, implementations, principles, and uses of functional
Fast parallel binary-trees for the shootout:
Control.Parallel.Strategies FTW!. Don Stewart announced that the
Computer Language Shootout recently got a quad core 64 bit machine, and
outlined a plan and some initial results for porting the Haskell
entries to take advantage of the available parallelism.
The initial view on typed sprintf and sscanf. oleg announced an
implementation of typed sprintf and sscanf functions sharing the same
formatting specifications, which also led to some interesting
discussion and alternative proposals.
Generalize groupBy in a useful way?. Bart Massey proposed changing
the implementation of groupBy to extend its usefulness for predicates
which are not equivalence relations.
Splitting SYB from the base package in GHC 6.10. JosÃ© Pedro MagalhÃ£es
initiated a discussion regarding splitting the SYB libraries out of
the base package for GHC 6.10.
The base library and GHC 6.10. Ian Lynagh initiated a discussion on
further splitting up the base package for GHC 6.10.
Functional references. Tim Newsham began a discussion on functional
references and the possibility of merging the existing four or five
implementations into something more standard.
Types and Trees. Matt Morrow wrote something about types and type
representations, involving some commutative diagrams and some code. I
haven't read it yet but it looks neat!
Research language vs. professional language. Ryan Ingram started an
interesting discussion on the future direction(s) of the Haskell
language proposal: ad-hoc overloading. Ryan Ingram proposed adding
ad-hoc name overloading to Haskell, prompting quite a bit of
Top Level <-. Ashley Yakeley originally asked whether there is any
interest in implementing a top level "<-" to run monadic code. This set
off a cascade of discussion the likes of which have been rarely seen on
the Cafe. I would tell you what the discussion has been about but I
must confess that I haven't read it.
