Haskell Weekly News
Issue 134 - October 10, 2009
Welcome to issue 134 of HWN, a newsletter covering developments in the
What with Don Stewart's call to 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 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!
CfPart: FMICS 2009, 2-3 November 2009, Final Call. FMICS 2009 workshop
chair announced the final call for particpaction for FMICS 2009
ICFP videos now available. Wouter Swierstra announced the
availablity of videos from the International Conference on Functional
GPipe-1.0.0: A functional graphics API for programmable GPUs. Tobias
Bexelius 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 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 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 announced HTZAAR, a Haskell
implementation of TZAAR
Graphalyze-0.8.0.0 and SourceGraph-0.5.5.0. Ivan Lazar Miljenovic
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 announced a new version of TxtSushi,
a set of command line utilities for processing CSV and TSV files.
Applicative do? Philippa Cowderoy asked about a `do` like syntax
for Applicative functors.
How to add use custom preprocessor in cabal. Bernd Brassel asked
how to add a custom preprocessor to the build chain of a cabal file.
On DSLs - one last time. Gunther Schmidt summarized his impressions
on al the recent discussion of DSLs
What is a DSL? Oleg offered some insight into different
properties that can be part of a single tagless framework. He also
pointed to some slides and other materials such as a website here
and slides here about DSL implementations and definitions.
What is a DSL? Gunther Schmidt 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
asked another question about Finally Tagless DSLs and resolving an
issue with the implementation of 'lam'
