Utrecht Haskell Compiler -- first release, version 1.0.0 ======================================================== The UHC team is happy to announce the first public release of the Utrecht Haskell Compiler (UHC). UHC supports almost all Haskell98 features plus many experimental extensions. The compiler runs on MacOSX, Windows (cygwin), and various Unix flavors. Features: * Multiple backends, including a bytecode interpreter backend and a GRIN based, full program analysing backend, both via C. * Experimental language extensions, some of which have not been implemented before. * Implementation via attribute grammars and other high-level tools. * Ease of experimentation with language variants, thanks to an aspect-oriented internal organisation. Getting started & Download -------------------------- UHC is available for download as source distribution via the UHC home page: http://www.cs.uu.nl/wiki/UHC Here you will also find instructions to get started. Status of the implementation ---------------------------- Like any university project UHC is very much work in progress. We feel that it is mature and stable enough to offer to the public, but much work still needs to be done; hence we welcome contributions by others. UHC grew out of our Haskell compiler project (called Essential Haskell Compiler, or EHC) over the past 5 years. UHC internally is organised as a combination of separate aspects, which makes UHC very suitable to experiment with; it is relatively easy to build compilers for sublanguages, or to generate related tools such as documentation generators, all from the same code base. Extensions to the language can be described separately, and be switched on or of as need arises. Warning ------- Although we think that the compiler is stable enough to compile subtantial Haskell programs, we do not recommend yet to use it for any serious development work in Haskell. We ourselves use the GHC as a development platform! We think however that it provides a great platform for experimenting with language implementations, language extensions, etc. Mailing lists ------------- For UHC users and developers respectively: http://mail.cs.uu.nl/mailman/listinfo/uhc-users http://mail.cs.uu.nl/mailman/listinfo/uhc-developers Bug reporting ------------- Please report bugs at: http://code.google.com/p/uhc/issues/list The UHC Team -- Atze Dijkstra, Department of Information and Computing Sciences. /|\ Utrecht University, PO Box 80089, 3508 TB Utrecht, Netherlands. / | \ Tel.: +31-30-2534118/1454 | WWW : http://www.cs.uu.nl/~atze . /--| \ Fax : +31-30-2513971 .... | Email: atze(a)cs.uu.nl ............ / |___\

Haskell logo in TeX (tested for TeXLive >= 2007)
by Philip Hölzenspies 15 Apr '09

15 Apr '09

Dear all, Seeing people throw the new logo around in different formats, I thought I would do it up in TikZ (for those that don't know: graphics embedded in LaTeX). For convenience, I wrapped it in a .sty file. If people find this useful, I will try and submit it to CTAN as well. I'm open for bug reports or feature requests. You do need a proper TeXLive installation (at least a relatively recent version of TikZ; check whether "kpsewhich pgfkeys.sty" says anything, in which case you should be fine). I will write up documentation for this before I put it onto CTAN, but for now, you will have to do with the example illustrating most options: \documentclass{article} \usepackage{haskelllogo} \begin{document} \haskelllogo[outlines,splitlambda] \haskelllogo[splitlambda] \haskelllogo[outlines] \haskelllogo[splitlambda, rangle color=green, lambda body color=red, lambda leg color=red!50!yellow, upper equals color=black, lower equals color=brown ] \haskelllogo[grayscale] \haskelllogo[splitlambda,grayscale] \haskelllogo[seventies] \haskelllogo[seventies,outlines] \end{document} The style is available at: http://www.cs.utwente.nl/~holzensp/haskelllogo.sty Enjoy! Regards, Philip

deriving Show for GADT?
by nr＠cs.tufts.edu 14 Apr '09

14 Apr '09

I've got a fairly large GADT for which I wished to use deriving (Show) but I got a mysterious error message: Exp.hs:13:11: Can't make a derived instance of `Show (Exp a)' (`Exp' has non-Haskell-98 constructor(s)) In the data type declaration for `Exp' This is from GHC. Does anybody know a compiler option or other trick that will coax the compiler into producing a Show instance. (I know I can write one by hand, but I'd rather not bother.) Norman

CFP Trends in Functional Programming
by Horváth Zoltán 14 Apr '09

14 Apr '09

Third call for papers 10th SYMPOSIUM ON TRENDS IN FUNCTIONAL PROGRAMMING TFP 2009 SELYE JANOS UNIVERSITY, KOMARNO, SLOVAKIA June 2-4, 2009 http://www.inf.elte.hu/tfp_cefp_2009 *** Submission deadline extended until 10th of May! *** The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming languages, focusing on providing a broad view of current and future trends in Functional Programming. It aspires to be a lively environment for presenting the latest research results. Acceptance for the conference is based on full papers or extended abstracts, and a formal post-symposium refereeing process selects the best articles presented at the symposium for publication in a high-profile volume. TFP 2009 is hosted by the Selye Janos University, Komarno, Slovakia, and it is co-located with the 3rd Central-European Functional Programming School (CEFP 2009), which is held immediately before TFP 2009 (May 25-30). IMPORTANT DATES (ALL 2009) * Paper Submission: May 10 (extended) * Notification of Acceptance: May 12 * Camera Ready Symposium Proceedings Paper: May 14 * TFP Symposium: June 2-4, 2009 * Post Symposium Paper Submission: June 30 * Notification of Acceptance: September 7 * Camera Ready Revised Paper: September 21 SCOPE OF THE SYMPOSIUM As part of the Symposium's focus on trends we therefore identify the following five article categories. High-quality articles are solicited in any of these categories: * Research: leading-edge, previously unpublished research. * Position: on what new trends should or should not be. * Project: descriptions of recently started new projects. * Evaluation: what lessons can be drawn from a finished project. * Overview: summarizing work with respect to a trendy subject. Articles must be original and not submitted for simultaneous publication to any other forum. They may consider any aspect of functional programming: theoretical, implementation-oriented, or more experience- oriented. Applications of functional programming techniques to other languages are also within the scope of the symposium. Contributions on the following subject areas are particularly welcomed: * Dependently Typed Functional Programming * Validation and Verification of Functional Programs * Debugging for Functional Languages * Functional Programming and Security * Functional Programming and Mobility * Functional Programming to Animate/Prototype/Implement Systems from Formal or Semi-Formal Specifications * Functional Languages for Telecommunications Applications * Functional Languages for Embedded Systems * Functional Programming Applied to Global Computing * Functional GRIDs * Functional Programming Ideas in Imperative or Object-Oriented Settings (and the converse) * Interoperability with Imperative Programming Languages * Novel Memory Management Techniques * Parallel/Concurrent Functional Languages * Program Transformation Techniques * Empirical Performance Studies * Abstract/Virtual Machines and Compilers for Functional Languages * New Implementation Strategies * Any new emerging trend in the functional programming area If you are in doubt on whether your article is within the scope of TFP, please contact the TFP 2009 program chairs, Zoltan Horvath and Viktoria Zsok at tfp2009(a)inf.elte.hu<mailto:tfp2009@inf.elte.hu> SUBMISSION AND DRAFT PROCEEDINGS Acceptance of articles for presentation at the symposium is based on the screening process of full papers (15 pages) and extended abstracts (at least 3 pages). TFP encourages PhD students to submit papers. PhD students may request the program committee to provide extensive feedback on their full papers at the time of submission. Full papers describing work accepted for presentation must be completed before the symposium for publication in the draft proceedings. Further details can be found at the TFP 2009 website. POST-SYMPOSIUM REFEREEING AND PUBLICATION In addition to the draft symposium proceedings, we continue the TFP tradition of publishing a high-quality subset of contributions in the Intellect series on Trends in Functional Programming.

13 Apr '09

--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20090413 Issue 113 - April 13, 2009 --------------------------------------------------------------------------- Welcome to issue 113 of HWN, a newsletter covering developments in the [1]Haskell community. Announcements xmobar-0.9.2. Andrea Rossato [2]announced the release of [3]xmobar-0.9.2, which features a fix for a longstanding resource leakage bug, new nested color definitions, and more. CFP Haskell Symposium 2009. Stephanie Weirich [4]reminded everyone that there are only 4 weeks until the submission deadline for the [5]2009 Haskell Symposium! hmatrix-static: statically-sized linear algebra. Reiner Pope [6]announced the release of [7]hmatrix-static, a thin wrapper over Alberto Ruiz's excellent [8]hmatrix library for linear algebra. The main additions of hmatrix-static over hmatrix are that vectors and matrices have their length encoded in their types, and vectors and matrices may be constructed and destructed using view patterns, affording a clean, safe syntax. haskellmode for Vim now at projects.haskell.org. Claus Reinke [9]announced that the Haskell mode plugins for Vim have just completed their move to their [10]new home, and took the opportunity to reiterate what they can do (quite a lot, it seems), and mention that some screencasts are available. MSem replacement for QSem. ChrisK [11]announced [12]MSem, a proposed replacement module for Control.Concurrent.QSem. Hac5 is almost upon us!. Sean Leather [13]reminded everyone that in six days, tens of crazy/obsessed, type-safe, functional programmers will be converging on Utrecht to commence execution of the [14]5th Haskell Hackathon, from April 17-19, 2009 in Utrecht, The Netherlands! The local organizing team welcomes you all and looks forward to all of the new developments that come out of everyone's undying quest to write more and better code. Yogurt-0.4. Martijn van Steenbergen [15]announced version 0.4 of [16]Yogurt, a functional MUD client. Version 0.4 makes Yogurt available as a standalone executable that is able to dynamically load and reload Yogurt scripts. Elerea, another FRP library. Patai Gergely [17]announced the release of [18]Elerea, aka "Eventless reactivity", a minimalistic FRP implementation that comes with a convenient applicative interface, supports recursive definition of signals and signals fed from outside by IO actions, plays nice with resources, and is the result of some furious hacking. There are working examples to show off the current capabilities of the library, found in the separate [19]elerea-examples package. tree-monad 0.2. Sebastian Fischer [20]announced version 0.2 of the [21]tree-monad package, which provides instances of MonadPlus that represent the search space of non- deterministic computations as a tree. Version 0.2 implements an optimized CPS version of the tree. HCard -- A library for implementing card-like structures.. Joe Fredette [22]announced the release of [23]HCard, a library which supports a card-like data structures and uses associated types to provide shuffling, dealing, and other facilities. It's general enough to support many different types of playing cards; it currently comes with the common "French Deck" (4-suit, 13 card deck that is very common in the US) implemented and an example cribbage scoring application. SVGFonts 0.1. Tillmann Vogt [24]announced his first Haskell library, [25]SVGFonts 0.1, which parses the relatively unknown SVG Font format to produce outlines of characters. The big advantage of this format is that it is XML, which means easy parsing and manipulating. network-bytestring 0.1.2. Johan Tibell [26]announced a new release of [27]network-bytestring, a Haskell library for fast socket I/O using ByteStrings. New in this release is support for scatter/gather I/O (also known as vectored I/O). Scatter/gather I/O provides more efficient I/O by using one system call to send several separate pieces of data and by avoiding unnecessary copying. Jobs Lecturer in Computer Science, University of Leicester. Roy L. Crole [28]announced an opening for a lectureship at the University of Leicester. The successful candidate will have a strong or promising research record in computer science, with a background in formal foundations (either algorithms and complexity, or semantics of programming or modelling languages), and will be able to contribute to undergraduate and postgraduate teaching and supervision in software engineering. Blog noise [29]Haskell news from the [30]blogosphere. * Mark Wassell: [31]Edge Detection in Haskell. * Sean Leather: [32]Latest on the incremental fold and attributes. * Sean Leather: [33]Haskell mode for Vim on a Mac. * Sean Leather: [34]Incremental attributes. * >>> Human Constraints: [35]Haskell Type Hackery. * LHC Team: [36]A new beginning.. * London Haskell Users Group: [37]Don Stewart: Engineering Large Projects in Haskell: A Decade of Haskell at Galois. * Ulisses Costa: [38]More Hylomorphisms in Haskell. * Ulisses Costa: [39]Anamorphisms in Haskell. * London Haskell Users Group: [40]Next Meeting: Don Stewart from Galois. * LHC Team: [41]Hello world!. * mightybyte: [42]Adding Authentication to the Blog App. * Leon Smith: [43]Polynomial multiplication. * Joe Fredette: [44]Card games, scorekeeping, and ...
