Call for Papers 4rd Informal ACM SIGPLAN Workshop on Mechanizing Metatheory Edinburgh, Scotland Co-located with ICFP'09. http://www.cis.upenn.edu/~sweirich/wmm/ Important Dates * Submission deadline: 19 June 2009 * Author Notification: 24 July 2009 * Workshop: 4 September 2009 Workshop Description Researchers in programming languages have long felt the need for tools to help formalize and check their work. With advances in language technology demanding deep understanding of ever larger and more complex languages, this need has become urgent. There are a number of automated proof assistants being developed within the theorem proving community that seem ready or nearly ready to be applied in this domain-yet, despite numerous individual efforts in this direction, the use of proof assistants in programming language research is still not commonplace: the available tools are confusingly diverse, difficult to learn, inadequately documented, and lacking in specific library facilities required for work in programming languages. The goal of this workshop is to bring together researchers who have experience using automated proof assistants for programming language metatheory, and those who are interested in using tool support for formalizing their work. One starting point for discussion will be the obstacles that hinder mechanization (whether they be pragmatic or technical), and what users and developers can do to overcome them. Format The workshop will consist of presentations by the participants, selected from submitted abstracts. It will focus on providing a fruitful environment for interaction and presentation of ongoing work. Participants are invited to submit working notes, source files, and abstracts for distribution to the attendees, but as the workshop has no formal proceedings, contributions may still be submitted for publication elsewhere. (See the SIGPLAN republication policy for more details.) Scope The scope of the workshop includes, but is not limited to: * Tool demonstrations: proof assistants, logical frameworks, visualizers, etc. * Libraries for programming language metatheory. * Formalization techniques, especially with respect to binding issues. * Analysis and comparison of solutions to the POPLmark challenge. * Examples of formalized programming language metatheory. * Proposals for new challenge problems that benchmark programming language work. Submission Guidelines Email submissions to urbanc AT in.tum.de. Submissions should be no longer than two pages in PDF and printable on A4 sized paper. Persons for whom this poses a hardship should contact the program chair. Conference Organization Program Committee * Nick Benton, Microsoft Research Cambridge * Olivier Danvy, University of Aarhus * Daniel Licata, Carnegie Mellon University * Francois Pottier, INRIA Paris-Rocquencourt * Christian Urban, TU Munich (chair) Workshop Organizers * Karl Crary, Carnegie Mellon University * Michael Norrish, National ICT Australia * Stephanie Weirich, University of Pennsylvania Previous Workshops * Victoria, 2008 * Freiburg, 2007 * Portland, 2006 ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

ANNOUNCE: jhc 0.6.0 Haskell Compiler
by John Meacham 24 Mar '09

24 Mar '09

Hi, I am pleased to announce jhc 0.6.0, It has been a long time since an official release, so there have been a lot of changes. Jhc is an optimizing haskell compiler that focuses on creating fast and portable code. Jhc is still mainly of interest to jhc hackers and developers than the general haskell public, but it is starting to see use in embedded development with haskell so I decided to make more public announcements of major releases in the future. some links: The jhc homepage: http://repetae.net/computer/jhc/ Installation Instructions: http://repetae.net/computer/jhc/building.shtml The jhc manual: http://repetae.net/computer/jhc/manual.html And I am happy to announce, there is now a yum repository* for jhc and my other projects (such as DrIFT), so if you use an rpm based linux distribution, you can keep up to date with jhc official releases by doing: ; rpm -i http://repetae.net/yum/repetae-repo-1.0-3.noarch.rpm ; yum install jhc A couple recent changes: jhc now comes bundled with the 'containers' and 'applicative' library making it much easier to compile many haskell programs out there. (Data.Graph, Data.IntMap, Data.IntSet, Data.Map, Data.Sequence, Data.Set, Data.Tree, Control.Applicative, Control.Arrow, Control.Category, Data.Foldable, Data.Traversable) signifigant speed and resource usage improvements in compilation time. transparent cross compilation support for creating windows programs on a unix box. (or iPhone/Nokia Tablet/etc..) If you are interested in jhc development, please sign up on the jhc mailing list here: http://www.haskell.org/mailman/listinfo/jhc John * I would love to get proper 'deb's and BSD packages built also automatically, if anyone wants to help with this, please join the list and let us know. -- John Meacham - ⑆repetae.net⑆john⑈

[ANN] ansi-terminal, ansi-wl-pprint - ANSI terminal support for Haskell
by Max Bolingbroke 21 Mar '09

21 Mar '09

These two packages allow Haskell programs to produce much richer console output by allowing colorisation, emboldening and so on. Both Unix-like (OS X, Linux) and Windows operating systems are supported (via a pure Haskell ANSI emulation layer for Windows). Examples, screenshots, and lots more information about how to get the packages are available at the freshly-minted homepages: http://batterseapower.github.com/ansi-terminal/ http://batterseapower.github.com/ansi-wl-pprint/ These two packages have actually been in stealth release mode on Hackage for some time. However, they seem to be getting some use and I'm not getting any bug reports, so I figure that they /must/ be stable enough to make a proper announcement :-) Cheers, Max (p.s: the GitHub "pages" feature seems to be absolutely ace - highly reccomended! http://pages.github.com/)

Haskell Weekly News: Issue 110 - March 21, 2009
by Brent Yorgey 21 Mar '09

21 Mar '09

--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20090321 Issue 110 - March 21, 2009 --------------------------------------------------------------------------- Welcome to issue 110 of HWN, a newsletter covering developments in the [1]Haskell community. [2]Facebook apps with Happstack, [3]Sudoku with Cryptol, what next? Tic-tac-toe with darcs? Anyway, lots of neat stuff this week, including new releases of [4]GHC, [5]jhc, and the [6]Monad.Reader, some [7]fun [8]visualizations, and more. Also, students: apply to work on a [9]Haskell project for the Google Summer of Code! Announcements GHC 6.10.2 Release Candidate 1. Ian Lynagh [10]announced the [11]first release candidate for GHC 6.10.2. Please test as much as possible; bugs are much cheaper if we find them before the release! jhc 0.6.0 Haskell Compiler. John Meacham [12]announced the release of [13]jhc 0.6.0. Safe Lazy IO in Haskell. Nicolas Pouillard [14]announced the [15]safe-lazy-io package that provides special types and combinators for performing safe lazy I/O. game-tree - a library for searching game trees. Colin Paul Adams [16]announced [17]game-tree 0.1.0.0, which provides a class for dynamic game trees, and purely functional algorithms for searching them. random-shuffle package. Manlio Perillo [18]announced the availability of the [19]random-shuffle package, which is based on [20]Oleg's description. random-stream package. Manlio Perillo [21]announced the [22]random-stream package, which provides a portable interface for the operating system source of pseudo random data. Supported sources are Unix /dev/urandom, Win32 CryptGenRandom and OpenSSL pseudo random numbers generator. language-python. Bernie Pope [23]announced the [24]language-python package, which provides a parser (and lexer) for Python, written in Haskell. Currently it only supports version 3 of Python (the most recent version), but it will support version 2 in the future. Google Summer of Code. Malcolm Wallace [25]announced that haskell.org has once again been accepted as a mentoring organisation for the 2009 Google Summer of Code. Student applications open on Monday (23rd March) at 1900 UTC, for a period of 12 days (until Fri 3rd April, also at 1900 UTC). Students applicants are encouraged to interact with the community via mailing lists, prior, during, and after the submission of their ideas for projects. Because (sadly) the darcs community did not get accepted as a separate organisation this year, haskell.org will be willing to accept proposals relating to darcs. regex-tdfa-1.1.0. ChrisK [26]announced the release of [27]regex-tdfa-1.1.0. This version is a small performance update to the old regex-tdfa-1.0.0 version. Previously all text (e.g. ByteString) being search was converted to String and sent through a single engine; the new version uses a type class and SPECIALIZE pragmas to avoid converting to String. This should make adding support for searching other Char containers easy to do. Haskell on your system? Information wanted!. Don Stewart [28]announced that haskell.org now features links to wiki pages explaining how to obtain Haskell on windows, mac osx and linux and bsd. If you're a distro maintainer for these systems, please consider adding relevant pointers to the pages, so that users of these systems can find all the info they need. libffi 0.1 released. Remi Turk [29]announced the release of [30]libffi 0.1, bindings to the C library libffi, allowing C functions to be called whose types are not known before run-time. Haskell Logo Voting has started!. Eelco Lempsink [31]announced that voting has begun to choose the new Haskell logo. All subscribed to haskell-cafe should have received a ballot; if you are not directly subscribed, you can still send ballot requests until the end of the competition (March 24, 12:00 UTC). Make sure the message contains 'haskell logo voting ballot request' in the subject. A long discussion of what color to paint the bike shed and why this particular bike shed will not do for storing bikes ensued. The Monad.Reader (13). Wouter Swierstra [32]announced that a new issue of [33]The Monad.Reader, a quarterly magazine about functional programming, is now available. Issue 13 consists of the following four articles: "Rapid Prototyping in TEX" by Stephen Hicks; "The Typeclassopedia" by Brent Yorgey; a Real World Haskell book review by Chris Eidhof and Eelco Lempsink; and "Calculating Monads with Category Theory" by Derek Elkins. dzen-utils 0.1. Felipe Lessa [34]announced the release of [35]dzen-utils 0.1, which contains various utilities for creating dzen input strings in a type-safe way using some combinators, including the ability to apply colors locally (instead of applying for everything beyond some point). It can also emulate dbar and gdbar, do automatic padding, and more. Discussion transformers versus mtl. Ganesh Sittampalam began a [36]discussion on the relative status of the 'transformers' and 'mtl' packages. least fixed points above something. Jens Blanck [37]asked about a function to compute fixed points starting from a seed value (as opposed to computing the least defined fixed point). Type equality proof. Martijn van Steenbergen [38]requested feedback on a proposed module collecting utilities for working with type equality proofs. What unsafeInterleaveIO is unsafe. Yusaku Hashimoto began a [39]discussion by asking why unsafeInterleaveIO is considered unsafe, or under what circumstances its use can be considered safe. Jobs How do students learn Haskell? Postgraduate project at University of Kent. S.J.Thompson [40]announced that funding is available for a [41]postgraduate project to study how students learn Haskell, based on the wealth of data collected through the instrumented version of the [42]Helium system for Haskell. The project will be supervised by Simon Thompson and Sally Fincher, in collaboration with Jurriaan Hage, Utrecht University.
