Haskell Weekly News: May 2, 2009
Welcome to issue 116 of HWN, a newsletter covering developments in the Haskell community.
GHC 6.10.3 prerelease. Ian Lynagh announced a prerelease version of GHC 6.10.3. There have been very few changes relative to 6.10.2. Unless any major problems are uncovered, the final release is expected to be built in a couple of days.
graphviz-2009.5.1. Ivan Lazar Miljenovic announced version 2009.5.1 of the graphviz library, which provides a Haskell interface to the GraphViz program. Major changes include support for polyparse >= 1.1, dependency on GHC 6.10.*, functions from the Graphalyze library, and more.
TraverseAccum: an effectful accumulating map.. Florent Balestrieri posted some code implementing an effectful accumulating map.
LondonHUG talk: Engineering Large Projects in Haskell. Don Stewart posted slides from last week's London HUG talk, which attempts to document some of the tips and tricks Galois has accumulated using Haskell commercially for the past 10 years.
Bamse-0.9.4, a Windows Installer generator. Sigbjorn Finne announced a new version of Bamse, a package and application for letting you quickly put together Windows Installers for your software projects/products from within the comforts of Haskell. New in this release is the support for generating MSIs from your Cabal projects, having them either be built from source or just have them be installed and registered at install-time.
control-monad-exception-0.1: Explicitly typed exceptions. Pepe Iborra announced the control-monad-exception package, which provides explicitly typed exceptions for Haskell. The type of a computation in the EM monad carries a list of the exceptions that the computation may throw. A exception is raised with 'throw', which in addition adds it to the type, and captured with 'catch', which correspondingly removes it from the type. Only safe computations (all exceptions handled) can escape from the monad.
Haskell File Manager. Michael Dever announced the first release of Haskell File Manager, a program for viewing/managing the files on your computer. It has all the common functionality you would expect from your current file manager, copying, moving, deleting, renaming, opening and searching.
uu-parsinglib-2.0.0. S. Doaitse Swierstra announced the release of uu-parsinglib, the first version of the new parsing combinator library package from Utrecht University. Features include online result construction, much simpler internals than the combinators in the uulib package, error correction, parsing ambiguous grammars, a monadic interface, and more.

Quotes of the Week
- MonadState: Do not try to change the state; that's impossible. Instead only try to realize the truth: There is no state.
- Baughn: Those who would give up essential laziness for a little ephemeral performance, deserve neither laziness nor performance.
- Axman6: what's @flush do? saves stuff to dick?
- bos: Crummy languages give static types a bad name.
