Announcements
----

storable-record. Henning Thielemann announced storable-record, a small package for simplified declaration of Storable instances for records. It may be used as an alternative to the c2hs preprocessor. It was made possible by advanced applicative technology, a cutting edge LCM monoid and an incredible constructor power tower.

Haskell Communities and Activities Report (16th ed., May 2009). Janis Voigtlaender announced the availability of the 16th Haskell Communities and Activities Report.

hledger 0.5 released. Simon Michael announced  the release of version 0.5 of hledger, a (mostly) text-mode double-entry accounting tool that generates precise activity and balance reports from a plain text journal file.

New repository and trac for haskell-src-exts. Niklas Broberg announced some new infrastructure for the haskell-src-exts package, set up in preparation for his GSoC project. with the HSP packages, it's now old enough to be allowed to live on its own. There is also a bug tracker. Please help by reporting any bugs you come across, or by requesting new and cool features.

bsd-sysctl 1.0.3. Maxime Henrion announced the release of bsd-sysctl 1.0.3, a package that provides a System.BSD.Sysctl module allowing access to the C sysctl(3) API. It should fully work on FreeBSD, NetBSD and Mac OS X platforms.

multirec-binary. Sebastiaan Visser announced the release of multirec-binary, which allows generic derivation of Data.Binary instances using the MultiRec library.

(Pre-) Announce: Data.GDS 0.1.0. Uwe Hollerbach (pre-) announced Data.GDS, a small module to write and (eventually) read GDS files, a classic format of the semiconductor industry. The module can currently generate GDS files with a fairly low-level interface; planned future versions (which will be uploaded to Hackage) will have a higher-level interface and be able to parse GDS files as well.

new version of uu-parsinglib. S. Doaitse Swierstra announced that a new version of the uu-parsinglib library has been uploaded to hackage. It is now based on Control.Applicative where possible. Be warned that functions like some and many will be redefined in the future.

Job for someone: make a VM image for GHC development. Simon Marlow suggested  a useful project for someone looking for something to do: create a VM image of a Linux system with a complete GHC development environment set up and ready to go.

My attempt at Haskell USB. Mauricio announced some Haskell bindings to libusb, and gave another plug for his bindings-common package, which makes it easier to generate Haskell bindings to low-level libraries.

second alpha release of OSX haskell platform installer. Gregory Collins announced a second candidate release for the OSX Haskell Platform installer. Please try it out!

Release Schedule for 2009.2.0.2. Don Stewart announced the release schedule for the next minor release of the 2009.2.0 branch of the Haskell Platform. The freeze for package changes will be Wednesday 1 July, and the release is scheduled for Monday 13th July.

hscamwire, for IIDC1394 cameras. Frederick Ross announced the release of hscamwire 0.1, which provides a nice Haskellized layer over Camwire, a library to connect to IIDC1394 cameras (most scientific and industrial Firewire cameras) on Linux.

Safe and generic printf with C-like format string. oleg announced some code to implement a type-safe polyvariadic version of printf, which is also integrated with Show so that any showable type can be printed.

A library for serial ports. Frederick Ross announced the release of serial-0.1, a library for line-oriented interaction with serial ports on POSIX compatible systems.

wp-archivebot 0.1 - archive Wikipedia's external links in WebCite. Gwern Branwen announced  wp-archivebot, a relatively simple little script which follows all the links in a RSS feed, combs the destination for http:// links, and submits them to WebCite.

memscript-0.0.0.2. Ki Yung Ahn announced memscript, a command line utility for memorizing scriptures or any other text.

HSH 2.0.0. John Goerzen announced the release of version 2.0.0 of HSH, the Haskell shell scripting library. This version features a complete rewrite of the core using System.Process, a drastic reduction in code size and complexity, cross-platform support, and a simpler and more flexible API.

atom-0.0.5. Tom Hawkins announced version 0.5 of the atom library, a DSL for embedded hard realtime applications. This version includes a few bug fixes and doc improvements.

heap-1.0.0. Stephan Friedrichs announced a rewrite of the heap package, heap-1.0.0. It is not 100% compatible with version 0.6.0, but provides major improvements, including a better mechanism for instantiating min-, max-, min-prio- and max-prio-heaps, and faster {from,to}{Asc,Desc}List conversions.

The Haskell Platform 2009.2.0.1. Don Stewart announced the second release (2009.2.0.1) of the Haskell Platform, a single, standard Haskell distribution for everyone. The specification, along with installers (including Windows and Unix installers for a full Haskell environment) are available.

code reviewers wanted for hashed-storage (darcs). Eric Kow solicited  anyone with a few spare hours this summer willing to help the Darcs project as a code reviewer for the standalone hashed-storage module, which will be used by Darcs in the future. No Darcs experience is needed!

Google Summer of Code
----

Progress updates from participants in the 2008 Google Summer of Code.

Haddock improvements. Isaac Dupree has begun looking at the Haddock code, and has a question about which of two options he should pursue.

EclipseFP. Thomas Ten Cate has posted an explanation of how the Scion client/server model works.

Space profiling. Gergely Patai has uploaded a preliminary version of the hp2any core library which handles heap profiles both during and after execution. He has also posted some pretty graphs generated by a simple utility built on top of the core library.

haskell-src-exts. Niklas Broberg has begun work by making a list of all language extensions and the ways in which they affect lexing and parsing, since haskell-src-exts will need to be parameterized over these extensions.

Fast Darcs. Petr Rockai has posted two detailed progress reports already, with many changes to both the standalone hashed-storage library and a fork of darcs which uses it.
