COMPILE regression in Apr 2010 snapshot (?)
by Madhu 27 Apr '10

27 Apr '10

Helu, here is an unpolished test case to show the problem: -=-=- (defmacro frob-keyvals-string (string) (with-input-from-string (stream string) `(progn ,@(loop for key = (let ((x (read stream nil stream))) (if (eq x stream) (loop-finish) x)) for val = (read stream) for comment = (read stream) collect (list 'defvar key (list 'quote val) (string comment)))))) (frob-keyvals-string " foo fooval foocomment bar barval barcomment car carval carcomment") -=-=- When compiled with COMPILE-FILE in the 2010-04 snapshot, the above snippet appears to recompile the macro definition as many times as there are DEFVARs in the macro expansion. -- Madhu

ELW 2010 deadline extension -- April 25th
by Didier Verna 21 Apr '10

21 Apr '10

+------------------------------------------------------------+ | CALL FOR PAPERS | | 7th European Lisp Workshop | | June 22 2010, Maribor, Slovenia, co-located with ECOOP | +------------------------------------------------------------+ Important Dates =============== Submission deadline: April 25, 2010 ** EXTENDED ** Notification of acceptance: May 05, 2010 ECOOP early registration deadline: May 10, 2010 7th European Lisp Workshop: June 22, 2010 Please note that registration must be done with ECOOP itself. For more information visit http://www.european-lisp-workshop.org Contact: Didier Verna, didier(a)lrde.epita.fr Invited Speaker =============== Manuel Serrano (INRIA, France) http://www-sop.inria.fr/members/Manuel.Serrano/ Overview ======== "...Please don't assume Lisp is only useful for Animation and Graphics, AI, Bio-informatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list." -- Kent Pitman Lisp, one of the eldest computer languages still in use today, is gaining momentum again. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch, making it the ideal candidate for writing Domain Specific Languages. Common Lisp, with the Common Lisp Object System (CLOS), was the first object-oriented programming language to receive an ANSI standard and remains the most complete and advanced object system of any programming language, while influencing many other object-oriented programming languages that followed. This workshop will address the near-future role of Lisp-based languages in research, industry and education. We solicit contributions that discuss the opportunities Lisp provides to capture and enhance the possibilities in software engineering. We want to promote lively discussion between researchers proposing new approaches and practitioners reporting on their experience with the strengths and limitations of current Lisp technologies. The workshop will have two components: there will be formal talks, and interactive turorial/demo/coding sessions. Papers ====== Formal presentations in the workshop should take between 20 minutes and half an hour; additional time will be given for questions and answers. Suggested topics include (but are not limited to): - Context-, aspect-, domain-oriented and generative programming - Macro-, reflective-, meta- and/or rule-based development approaches - Protocol meta-programming and libraries - New language features and abstractions - Software evolution - Development aids - Persistent systems - Dynamic optimization - Implementation techniques - Hardware Support - Efficiency, distribution and parallel programming - Educational approaches and perspectives - Experience reports and case studies Interactive Tutorial/Demo/Coding Sessions ========================================= Additionally, we invite less formal talks in the form of interactive tutorial/demo/coding sessions. The purpose of these sessions is both to demonstrate and receive feedback on any interesting Lisp system, either stable or under development. Being less formal than technical paper presentations, these sessions are expected to be highly interactive. Submission Guidelines ===================== Potential contributors are encouraged to submit: - a long paper (around 10 pages) presenting scientific and/or empirical results about Lisp-based uses or new approaches for software engineering purposes, - a short essay (5 pages) defending a position about where research, practice or education based on Lisp should be heading in the near future, - a proposal for an interactive tutorial/demo/coding session (1-2 pages) describing the involved library or application, and the subject of the session. Papers (both long and short) should be formatted following the ACM SIGS guidelines and include ACM classification categories and terms (see below). Authors will later be required to sign an ACM copyright form, as the workshop proceedings will be published in the ACM Digital Library. For more information on the submission guidelines and the ACM keywords, see: http://www.acm.org/sigs/publications/proceedings-templates http://www.acm.org/about/class/1998 Submissions should be uploaded to Easy Chair, at the following address: http://www.easychair.org/conferences/?conf=elw2010 Organizers ========== Didier Verna, EPITA Research and Development Laboratory, Paris Charlotte Herzeel, Programming Technology Lab, Vrije Universiteit, Brussel Robert Strandh, LaBRI, University of Bordeaux 1, France Christophe Rhodes, Goldsmiths College, University of London -- Resistance is futile.

Apologies to recipients of multiple copies of this: 3rd European Lisp Symposium =========================== May 6-7, 2010, Fundacao Calouste Gulbenkian Lisbon, Portugal Call for Participation ~~~~~~~~~~~~~~~~~~~~~~~ Registration for the 3rd European Lisp Symposium (ELS 2010) is now open at [http://www.european-lisp-symposium.org/] Scope and Programme Highlights ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The purpose of the European Lisp Symposium is to provide a forum for the discussion of all aspects of the design, implementation and application of any of the Lisp dialects. We encourage everyone interested in Lisp to participate. As well as presentations of the accepted technical papers and tutorials, the programme features the following highlights: - Kent Pitman of HyperMeta Inc. will offer reflections on Lisp Past, Present and Future; - Pascal Costanza will lead a tutorial session on Parallel Programming in Common Lisp; - Matthias Felleisen of PLT will talk about languages for creating programming languages; - there will be opportunities for attendees to give lightning talks and demos of late-breaking work. Social events ~~~~~~~~~~~~~~ - Symposium banquet (included with registration) - Excursion to Sintra (optional), for six centuries the favourite Summer residence of the Kings of Portugal, who were attracted by cool climates and the beauty of the town's setting. Programme Chair ~~~~~~~~~~~~~~~~ Christophe Rhodes, Goldsmiths, University of London, UK Local Chair ~~~~~~~~~~~~ Antonio Leitao, Technical University of Lisbon, Portugal Programme Committee ~~~~~~~~~~~~~~~~~~~~ + Marco Antoniotti, Universita Milano Bicocca, Italy + Giuseppe Attardi, Universita di Pisa, Italy + Pascal Costanza, Vrije Universiteit Brussel, Belgium + Irene Anne Durand, Universite Bordeaux I, France + Marc Feeley, Universite de Montreal, Canada + Ron Garret, Amalgamated Widgets Unlimited, USA + Gregor Kiczales, University of British Columbia, Canada + Antonio Leitao, Technical University of Lisbon, Portugal + Nick Levine, Ravenbrook Ltd, UK + Scott McKay, ITA Software, Inc., USA + Peter Norvig, Google Inc., USA + Kent Pitman, PTC, USA + Christian Queinnec, Universite Pierre et Marie Curie, France + Robert Strandh, Universite Bordeaux I, France + Didier Verna, EPITA Research and Development Laboratory, France + Barry Wilkes, Citi, UK + Taiichi Yuasa, Kyoto University, Japan Registration ~~~~~~~~~~~~~ Registration is open at [http://www.european-lisp-symposium.org/] and costs EUR120 (EUR60 for students) until 22nd April, and EUR200 (EUR120 for students) afterwards.

April snapshot tagged
by Raymond Toy 01 Apr '10

01 Apr '10

The April snapshot has been tagged. Binaries will be uploaded soon. This snapshot includes support for internationalization. To bootstrap this, use boot-2010-02-1.lisp. You may also want to use the -P option for build.sh so that the pot and po files are updated. If you want to update the piglatin translation, you'll need to load tools/piglatin.lisp and run (do-translations). Also, a cricital bug in SSE2 has been fixed. GC hooks that used the floating-point would corrupt the SSE2 registers and cause computations to return, essentially, random results. This didn't affect x87. Ray
