ANNOUNCE: bindings-levmar-0.1.1
by Roel van Dijk 16 Sep '09

16 Sep '09

I am pleased to announce the release of bindings-levmar-0.1.1: http://hackage.haskell.org/package/bindings-levmar The most important change compared to the previous version is a custom configure script (copied from hmatrix) that detects which libraries are needed. The cabal file also has some flags which allow you to choose for instance intel's mkl library instead of the normal lapack (also copied from hmatrix). Happy hacking, Roel and Bas van Dijk

ANNOUNCE: Haskeline 0.6.2
by Judah Jacobson 15 Sep '09

15 Sep '09

I am pleased to announce the release of Haskeline 0.6.2: http://hackage.haskell.org/package/haskeline (Make sure to run cabal update first to get its updated dependencies.) Haskeline provides a user interface for line input in command-line programs. The library is similar in purpose to readline or editline, but since it is written in Haskell it is (hopefully) more easily used in other Haskell programs. With this release, thanks to much appreciated feedback and suggestions from the community, Haskeline's features become more competitive with its C alternatives. Improvements include: * A multitude of new emacs and vi bindings: http://trac.haskell.org/haskeline/wiki/KeyBindings * A new preference 'historyDuplicates' to remove repeated history entries * Recognize PageUp and PageDown keys * Compatibility with ghc-6.12 * Correct width calculations for Unicode combining characters Documentation, development and mailing list information can be found at: http://trac.haskell.org/haskeline Best, -Judah

PEPM'10 - Last CFP (Submission: 6 Oct 09, Notification: 29 Oct 09)
by Janis Voigtlaender 15 Sep '09

15 Sep '09

=============================================================== CALL FOR PAPERS ACM SIGPLAN 2010 Workshop on Partial Evaluation and Program Manipulation (PEPM'10) Madrid, January 18-19, 2010 (Affiliated with POPL'10) http://www.program-transformation.org/PEPM10 =============================================================== INVITED SPEAKERS: * Lennart Augustsson (Standard Chartered Bank, UK) * Jeremy Siek (University of Colorado at Boulder, USA) IMPORTANT DATES: * Paper submission: Tue, October 6, 2009, 23:59, Apia time * Author notification: Thu, October 29, 2009 * Camera-ready papers: Mon, November 9, 2009 To facilitate smooth organization of the review process, authors are asked to submit a short abstract by October 1, 2009. SUBMISSION CATEGORIES: * Regular research papers (max. 10 pages in ACM Proceedings style) * Tool demonstration papers (max. 4 pages plus max. 6 pages appendix) TRAVEL SUPPORT: Students and other attendants in need can apply for a SIGPLAN PAC grant to help cover expenses. For details, see http://www.sigplan.org/PAC.htm. SCOPE: The PEPM Symposium/Workshop series aims to bring together researchers and practitioners working in the areas of program manipulation, partial evaluation, and program generation. PEPM focuses on techniques, theories, tools, and applications of analysis and manipulation of programs. The 2010 PEPM workshop will be based on a broad interpretation of semantics-based program manipulation in a continued effort to expand the scope of PEPM significantly beyond the traditionally covered areas of partial evaluation and specialization and include practical applications of program transformations such as refactoring tools, and practical implementation techniques such as rule-based transformation systems. In addition, it covers manipulation and transformations of program and system representations such as structural and semantic models that occur in the context of model-driven development. In order to reach out to practitioners, there is a separate category of tool demonstration papers. Topics of interest for PEPM'10 include, but are not limited to: * Program and model manipulation techniques such as transformations driven by rules, patterns, or analyses, partial evaluation, specialization, program inversion, program composition, slicing, symbolic execution, refactoring, aspect weaving, decompilation, and obfuscation. * Program analysis techniques that are used to drive program/model manipulation such as abstract interpretation, static analysis, binding-time analysis, dynamic analysis, constraint solving, type systems, automated testing and test case generation. * Analysis and transformation for programs/models with advanced features such as objects, generics, ownership types, aspects, reflection, XML type systems, component frameworks, and middleware. * Techniques that treat programs/models as data objects including meta-programming, generative programming, deep embedded domain-specific languages, program synthesis by sketching and inductive programming, staged computation, and model-driven program generation and transformation. * Application of the above techniques including experimental studies, engineering needed for scalability, and benchmarking. Examples of application domains include legacy program understanding and transformation, DSL implementations, visual languages and end-user programming, scientific computing, middleware frameworks and infrastructure needed for distributed and web-based applications, resource-limited computation, and security. We especially encourage papers that break new ground including descriptions of how program/model manipulation tools can be integrated into realistic software development processes, descriptions of robust tools capable of effectively handling realistic applications, and new areas of application such as rapidly evolving systems, distributed and web-based programming including middleware manipulation, model-driven development, and on-the-fly program adaptation driven by run-time or statistical analysis. PROCEEDINGS: There will be formal proceedings published by ACM Press. In addition to printed proceedings, accepted papers will be included in the ACM Digital Library. Selected papers may later on be invited for a journal special issue dedicated to PEPM'10. SUBMISSION GUIDELINES: Papers should be submitted electronically via the workshop web site. Regular research papers must not exceed 10 pages in ACM Proceedings style. Tool demonstration papers must not exceed 4 pages in ACM Proceedings style, and authors will be expected to present a live demonstration of the described tool at the workshop (tool papers should include an additional appendix of up to 6 extra pages giving the outline, screenshots, examples, etc. to indicate the content of the proposed live demo at the workshop). Authors using Latex to prepare their submissions should use the new improved SIGPLAN proceedings style (sigplanconf.cls, 9pt template). PROGRAM CO-CHAIRS: * John Gallagher (Roskilde University, Denmark, and IMDEA Software, Spain) * Janis Voigtländer (Technische Universität Dresden, Germany) PROGRAM COMMITTEE MEMBERS: * Wei-Ngan Chin (National University of Singapore, Singapore) * Michael Codish (Ben-Gurion University of the Negev, Israel) * Jim Cordy (Queen's University, Canada) * Nate Foster (University of Pennsylvania, USA) * Haifeng Guo (University of Nebraska at Omaha, USA) * Patricia Johann (University of Strathclyde, UK) * Oleg Kiselyov (FNMOC, USA) * Günter Kniesel (University of Bonn, Germany) * Viktor Kuncak (Ecole Polytechnique Fédérale de Lausanne, Switzerland) * Yanhong Annie Liu (State University of New York at Stony Brook, USA) * Andres Löh (Utrecht University, Netherlands) * Jan Midtgaard (Roskilde University, Denmark) * David Monniaux (National Center for Scientific Research (CNRS) and VERIMAG laboratory, France) * Akimasa Morihata (University of Tokyo, Japan) * Alberto Pettorossi (Università di Roma Tor Vergata, Italy) * João Saraiva (Universidade do Minho, Portugal) * Ganesh Sittampalam (Credit Suisse, UK) * Fausto Spoto (Università di Verona, Italy) * Harald Søndergaard (University of Melbourne, Australia) * Walid Taha (Rice University, USA)

ANN: CmdArgs - easy command line argument processing
by Neil Mitchell 14 Sep '09

14 Sep '09

Hi, I am pleased to announce CmdArgs v0.1. CmdArgs is a library for easy command line argument processing - taking the arguments passed into your program from getArgs and converting them into a structured value for use in your program. Compared to the System.Console.GetOpts library there are two key advantages: 1) The command line argument processors are shorter - in a typical case they are about 1/3 the size, 90 lines with getopts vs 30 simpler lines with CmdArgs (for HLint). 2) CmdArgs can support multiple mode command lines, such as those found in hpc, darcs and cabal. The guiding principle of CmdArgs is to try and write each piece of information only once, which makes the command line processing shorter, and eliminates many of the accidental copy-and-paste style bugs that are easy with getopts. CmdArgs requires GHC, but other than this restriction, I do not foresee any reason for anyone to use getopts over CmdArgs. To install use the standard cabal magic: cabal update && cabal install cmdargs Useful links Home page: http://community.haskell.org/~ndm/cmdargs/ Manual: http://community.haskell.org/~ndm/darcs/cmdargs/cmdargs.htm Haddock: http://hackage.haskell.org/packages/archive/cmdargs/latest/doc/html/System-… If you want to start using CmdArgs I recommend reading through the manual, and referring to the haddock documentation as necessary. I welcome any comments and bug reports. Thanks, Neil

ANNOUNCE: OpenGLRaw 1.1.0.0
by Sven Panne 13 Sep '09

13 Sep '09

A new version of the OpenGLRaw package has been uploaded to Hackage. * Use opaque newtypes for the basic OpenGL types, adding the common instances for them, too. Note that this might break programs which depend on the concrete representations. Use explicit conversions where necessary, making all assumptions explicit. * Fixed linking issues on Mac OS X, the package should work out of the box without any warnings or additional flags now. * Fall back to GetProcAddress on Windows when WGL doesn't find an API entry. This should fix problems using core functions with some driver/OS combinations. * Added support for OpenGL 3.2 and the latest NV extensions. * All extensions export all their functions/tokens/types, even if they are in the core. This will keep the extension module exports more stable. * Fixed the types of the glPixelMap functions, using GLsizei instead of GLint for the size, following the OpenGL specification. Cheers, S.

ANNOUNCE: GLUT 2.2.2.0
by Sven Panne 13 Sep '09

13 Sep '09

A new version of the GLUT package has been uploaded to Hackage. * Fixed linking issues on Mac OS X, the package should work out of the box without any warnings or additional flags now. * Handle additional mouse buttons via 'AdditionalButton Int' in the MouseButton type. * Made a few minor typing adjustments, which don't really matter for the type synonyms used for the basic OpenGL types so far, but which do matter for the upcoming datatype renamings for them. * Aesthetic improvements in the brick shader example. Cheers, S.
