Hopefully the line endings come out okay this week, I did a test
before sending it to the list, please let me know if you notice
anything awry. Just put a [HWN] in the subject line so my filter's
will catch it. </metaeditorial>

Issue 131 - September 18, 2009
---------------------------------------------------------------------------
Welcome to issue 131 of HWN, a newsletter covering developments in
the
[1]Haskell community.
Last week, I received an email from Mark Wotton about his project
[2]Hubris. I totally forgot to put it in the HWN last week, too busy
trying to figure out all the tools. So, I thought I'd make it up and
give him some special editorial status this week. Hubris is a bridge
between Ruby and Haskell, allowing you to call Haskell from Ruby.
It's
very cool, I highly suggest playing with it. Also, I've been
posting a
bit about the new HWN tools (dubbed "HWN2") on my [3]blog, there is
also a repo up at [4]patch-tag which will have all the code. If
there
is some interest in helping me, I'll try to come up with a TODO
list/Trac.
Announcements
hssqlppp, sql parser and type checker, pre-alpha. Jake Wheat
[5]announced his parser/type checker for SQL. It currently parses a
subset of PostGreSQL and PL/pgSQL, and can type check some
statements.
LambdaINet-0.1.0, Graphical Interaction Net Evaluator for Optimal
Evaluation. Paul L [6]announced a LambdaINet 0.1.0, available on
[7]Hackage. LambdaINet implements an interaction net based optimal
evaluator. With an interactive graphical interface allowing the
user to
view and directly manipulate the interaction net.
arbtt-0.1. Joachim Breitner [8]announced the Automatic Rule-Based
Time
Tracking tool on hackage. he has an introduction available [9]here.
A statistics library. Bryan O'Sullivan [10]announced the
imaginatively
named [11]statistics library. Which supports common discrete and
continuous probability distributions, Kernel density estimation,
Auto-correlation analysis, Functions over sample data, Quantile
estimation, and Re-sampling techniques.
CFP: JSC Special Issue on Automated Verification and Specification
of
Web Systems. [12]A Special Issue of the Journal of symbolic
computation
was announced. This issue is related to the topics of the Automated
Specification and Verification of Web Systems Workshop (WWV'09).
Read
the announcement for more details.
Haskeline 0.6.2. Judah Jacobson [13]announced the release of
Haskeline
0.6.2, available [14]here. Improvements over the last version
include,
new emacs and vi bindings, a new preference to remove repeated
history
entries, recognition of page-up and page-down keys, and more.
PEPM'10 - Last CFP (Submission: 6 Oct 09, Notification: 29 Oct 09).
Janis Voigtlaender [15]announced the Last Call for Papers for
PEPM'10,
see the announcement for more details.
Videos of HIW 2009. Malcolm Wallace [16]announced videos of all the
presentations/discussions at the recent Haskell Implementers
Workshop
2009, in Edinburgh, are now [17]online. The program of talks is
available [18]here.
Unification in a Commutative Monoid (cmu 1.1) and a new release of
Abelian group unification and matching (agum 2.2). John D. Ramsdell
[19]announced cmu 1.1, which provides unification in a commutative
monoid, also know as ACU-unification. The core computation finds the
minimal non-zero solutions to homogeneous linear Diophantine
equations.
The linear equation solver has been place in a separate module so it
can be used for other applications. He also announced agum 2.2,
which
provides unification and matching in an Abelian group, also know as
AG-unification and matching.
graphviz-2999.5.1.0. Ivan Lazar Miljenovic [20]announced a bug-fix
release of the GraphViz package, no major API changes occurred.
levmar-0.2, bindings-levmar-0.1.1. Bas van Dijk and Roel van Dijk
announced [21]new [22]versions of the levmar and bindings-levmar
packages. New features include automatic calculation of the Jacobian
via Conal Elliot's automatic differentiation from his vector-space
library.
CmdArgs - easy command line argument processing. Neil Mitchell
[23]announced CmdArgs 0.1. CmdArgs is a library for parsing
command-line arguments. It offers several improvements over GetOpts,
namely that the Command Line Argument Processors are shorter and
CmdArgs can support multiple-mode command lines such as those
found in
darcs, cabal, hpc, etc.
OpenGL 2.4.0.1. Sven Panne [24]announced a new version of the OpenGL
package, this version fixes a bug that didn't make it into the
previous
release.
OpenGLRaw 1.1.0.0. Sven Panne [25]announced a new version of the
OpenGLRaw package has been uploaded to Hackage.
Discussion
Thank you guys. Cristiano Paris took some time to thank us all from
-Cafe for helping him learn Haskell. You're welcome, Cristiano!
Unicode lexing in GHC and GHCi. Sean McLaughlin [26]asked about why
certain unicode characters parsed in GHCi without error, but not in
compiled code.
Help with FFI. Jose Prous [27]asked for some help with the foreign
function interface.
Ambiguous type variable with subclass instance. Andy Gimblett
[28]asked
about a particular ambiguous type error
Haskell -> .NET. Peter Verswyvelen [29]asked about the possibilities
for a .NET version of Haskell.
A thought about liberating Haskell's syntax. George Pollard
[30]suggested a new way to do templates, so that brace-like syntax
could be added without having to seriously hack GHC.
