Issue 54 - December 20, 2006
---------------------------------------------------------------------------
Welcome to issue 54 of HWN, a weekly newsletter covering developments
in the Haskell community.
A new release of the Edison data structures library, along with
several other new libraries, and some new Haskell articles in the
blogspace.
Announcements
Edison 1.2.1. Robert Dockins [1]announced the 1.2.1 release of
[2]Edison. Edison is a famous library of efficient, purely-functional
data structures in Haskell. Notable changes from the previous version
include: a new sequence implementation based on finger trees;
documentation fixes dealing with the licence; added a few methods to
EnumSet for wrapping and unwrapping the underlying Word

Basic serialisation library using SYB. Stefan O'Rear [3]announced
GenericSerialize, [4]a library for serialization using the existing
generic-programming framework. It is often advocated that support for
serialization should be added to the compiler (e.g. in the form of a
deriving(Binary)). With this project Stefan wants to show that the
existing infrastructure is sufficient, and has some advantages over a
dedicated serialization interface. GenericSerialize supports multiple
serialization modes.

vty 1.0. Stefan O'Rear [5]announced vty 1.0, a simple [6]terminal
interface library. It provides: handling of suspend/resume, window
resizes, computation of minimal differences, minimizes repaint area,
automatically decodes keyboard keys into (key,modifier) tuples, and
more!
5. http://article.gmane.org/gmane.comp.lang.haskell.general/14670
6. http://members.cox.net/stefanor/vty
Monad.Reader call for copy. Wouter Swierstra [7]reminded us that its
still not too late to write something for the next issue of [8]The
Monad.Reader! We have a nice issue slowly shaping up, but your
contribution is still very welcome. Get in touch with Wouter if you
intend to submit something -- the sooner you let him know what you're
up to, the better.

8. http://www.haskell.org/haskellwiki/TheMonadReader
Ranged Sets. Paul Johnson [9]announced that Ranged Sets now have a
Monoid instance, and singletons (i.e. a range holding a single value),
thanks to Jean-Philippe Bernardy.
9. http://article.gmane.org/gmane.comp.lang.haskell.general/14663
CalDims 1.0 (RC 1). schneegloeckchen [10]announced CalDims, a
calculator aware of units. Its available from [11]the Haskell wiki. It
includes support for user defined basic units and derrived units; user
defined functions; work sheets can be modified/saved via shell;
(1/3)*3 == 1 (No rounding errors); built-in feature to simplify units
and easy unit-conversion.

JoinCabal. Dougal Stanton [12]announced an alternative to mkcabal, for
initialising new cabal projects: [13]JoinCabal, available [14]via
darcs. JoinCabal will create stub sources files with a license header,
and appropriate license for you code, making it easier to set up a
valid cabal build system.

14. http://brokenhut.no-ip.org/~dougal/darcs/joincabal/
Haskell Vim plugin. Arthur van Leeuwen [15]announced a new [16]vim
plugin for Haskell providing some preliminary folding support, easy
insertion of type signatures into programs, and support for handling
.hi files.

Haskell'

18. http://thread.gmane.org/gmane.comp.lang.haskell.prime/1956/focus=1974
Discussion
Automonadization of code. Adam Megacz [19]asked if there any work on
automatic translation of code in some tiny imperative language into
Haskell code that uses the ST and/or IO monads (or perhaps even pure
functional code)?
19. http://thread.gmane.org/gmane.comp.lang.haskell.cafe/17326/focus=17326
What are the points in pointfree style?. Steve Downey [20]wondered
about the origin of the term 'points' in pointfree style.
20. http://thread.gmane.org/gmane.comp.lang.haskell.cafe/17560/focus=17560
Rebinding >>= for restricted monads. David Roundy [21]pondered
rebinding the >>= syntax in order to provide a more restricted monad.
21. http://thread.gmane.org/gmane.comp.lang.haskell.cafe/17646/focus=17646
#haskell reaches 300 users. Don Stewart [22]noticed that the
[23]#haskell IRC channel has now reached the 300 user mark, making it
one of the top 15 channels on the freenode network.

Quotes of the Week
* Cale: I spent a whole summer being paid to write a
nondeterministic search program in the list monad
* monochrom: 007 titles for Haskellers: fromForeignPtr withCString;
You Only lift Twice; Bottoms Are Forever; The Monad with the Pure
Function; For Your Types Only; A view to A seq; Licence to
killThread; iterate Never Dies; unsafePerformIO Is Not Enough.
* DavidRoundy: ... fun of haskell-cafe is that it's where all the
cool people hang out
* dons: Coding drunk in Haskell is ok though, its like drinking on a
passenger plane flight -- the stewards will prevent you from
hurting anyone. However, coding drunk in C is just scary, DUI
territory, and should not be allowed.
* JulianMorrison: Small startup companies are the expendable sensory
and feeding apparatus of the mainstream.
* droundy: With a higher-kinded monad and phantom existential
witness types, darcs would be very fun...
* dons: The alien rulers of the galaxy must surely use a statically
typed language with type inference
* dibblego: Java programmers prefer referential transparency too,
they just call it 'design patterns' or something
* tessier: After the last newbies head exploded trying to read
everything on that monad link there was a lot of paperwork. We'd
like to avoid doing that again.
