Issue 134 - October 10, 2009
---------------------------------------------------------------------------
   Welcome to issue 134 of HWN, a newsletter covering developments in the
   [1]Haskell community.

   What with Don Stewart's [2]call to [3]arms to lead Haskell to conquest
   over (E)DSL-land, I've once again tried to highlight discussion of
   EDSL's this week. Fortunately, it was actually more difficult choosing
   what _not_ to include this week, since there was so much discussion
   about DSLs and Syntax extensions (a related notion, in my opinion).
   Also, this week Bryan O'Sullivan put his Criterion Library to good use
   on the `text` package, leading to [4]code which is more than ten times
   faster than before! With all this fantastic news, I won't hold you up
   any longer, Haskellers, the Haskell Weekly News!

Announcements

   CfPart: FMICS 2009, 2-3 November 2009, Final Call. FMICS 2009 workshop
   chair [5]announced the final call for particpaction for FMICS 2009

   ICFP videos now available. Wouter Swierstra [6]announced the
   availablity of videos from the International Conference on Functional
   Programming (ICFP)

   GPipe-1.0.0: A functional graphics API for programmable GPUs. Tobias
   Bexelius [7]announced the first release of GPie, a functional graphics
   API for programmable GPUs.

   text 0.5, a major revision of the Unicode text library. Bryan
   O'Sullivan [8]announced a new, major version of the text package. New
   API features, and huge improvments in speed, as Bryan says, 'Get it
   while it's fresh on Hackage, folks!'

   vty-ui 0.2. Jonathan Daugherty [9]announced a new version of the vty-ui
   package, with fewer bugs, more widgets, and cleaner code due to new
   more powerful abstractions.

   htzaar-0.0.1. Tom Hawkins [10]announced HTZAAR, a Haskell
   implementation of TZAAR

   Graphalyze-0.8.0.0 and SourceGraph-0.5.5.0. Ivan Lazar Miljenovic
   [11]announced To keep this editor happy, Ivan released two new packaged
   in one announcement. This time, he's added Legend support to
   Graphalyze, but also many new changes to SourceGraph, including a
   legend so you can see what all the symbols mean, Better color support,
   and much more.

   TxtSushi 0.4.0. Keith Sheppard [12]announced a new version of TxtSushi,
   a set of command line utilities for processing CSV and TSV files.

Discussion

   Applicative do? Philippa Cowderoy [13]asked about a `do` like syntax
   for Applicative functors.

   How to add use custom preprocessor in cabal. Bernd Brassel [14]asked
   how to add a custom preprocessor to the build chain of a cabal file.

   On DSLs - one last time. Gunther Schmidt [15]summarized his impressions
   on al the recent discussion of DSLs

   What is a DSL? Oleg [16]offered some insight into different
   [17]properties that can be part of a single tagless framework. He also
   pointed to some slides and other materials such as a website [18]here
   and slides [19]here about DSL implementations and definitions.

   What is a DSL? Gunther Schmidt [20]posed the question, 'What is a DSL',
   and with some further questions added by yours truly, a lively
   discussion about the definition of a DSL ensued.

   Finally tagless - stuck with implementation of 'lam'. Gunther Schmidt
   [21]asked another question about Finally Tagless DSLs and resolving an
   issue with the implementation of 'lam'
