[parenscript-devel] Operator precedence bug
by Daniel Gackle 05 Feb '12

05 Feb '12

(let ((str "a") (n 1)) (+ str (+ n 1))) should produce "a2", but instead compiles to "str + n + 1" and produces "a11".

[parenscript-devel] Montreal Scheme/Lisp Users Group presentation
by Vladimir Sedach 27 Jan '12

27 Jan '12

Hello, Last week I gave a presentation about Parenscript to the Montreal Scheme/Lisp Users Group. The presentation is mostly about how Parenscript compiles CL to JavaScript, and it might be interesting to some people subscribed to this list. Links to the slides and other info is posted on my blog: http://carcaddar.blogspot.com/2012/01/upcoming-presentation-about-parenscri… François Pinard made an audio recording that is available for now at http://74.207.228.11/static/MSLUG-parenscript.mp3 Vladimir

[parenscript-devel] ELS2012 Zadar, Croatia, Call for Papers
by Marco Antoniotti 23 Jan '12

23 Jan '12

Apologies for the multiple postings... =========================================================================== European Lisp Symposium 2012, Zadar, Croatia, April 30th - May 1st, 2012 http://european-lisp-symposium.org The purpose of the European Lisp Symposium is to provide a forum for the discussion and dissemination of all aspects of design, implementation and application of any of the Lisp and Lisp-inspired dialects, including Common Lisp, Scheme, Emacs Lisp, AutoLisp, ISLISP, Dylan, Clojure, ACL2, ECMAScript, Racket, SKILL, and so on. We encourage everyone interested in Lisp to participate. The main theme of the 2012 European Lisp Conference is "Interoperabilty: Systems, Libraries, Workflows". Lisp based and functional-languages based systems have grown a variety of solutions to become more and more integrated with the wider world of Information and Communication Technologies in current use. There are several dimensions to the scope of the solutions proposed, ranging from "embedding" of interpreters in C-based systems, to the development of abstractions levels that facilitate the expression of complex context dependent tasks, to the construction of exchange formats handling libraries, to the construction of theorem-provers for the "Semantic Web". The European Lisp Symposium 2012 solicits the submission of papers with this specific theme in mind, alongside the more traditional tracks which have appeared in the past editions. We invite submissions in the following forms: Papers: Technical papers of up to 15 pages that describe original results or explain known ideas in new and elegant ways. Demonstrations: Abstracts of up to 4 pages for demonstrations of tools, libraries, and applications. Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes. Lightning talks: Abstracts of up to one page for talks to last for no more than 5 minutes. All submissions should be formatted following the ACM SIGS guidelines and include ACM classification categories and terms. For more information on the submission guidelines and the ACM keywords, see: http://www.acm.org/sigs/publications/proceedings-templates and http://www.acm.org/about/class/1998. Important dates: Jan 31st 2012: submission deadline Feb 21st 2012: acceptance results April 30th, 2012 Conference opens Program Commitee. Chair: Marco Antoniotti, Università degli Studi di Milano Bicocca, Milan, ITALY Local organizers: Damir Ćavar, Eastern Michigan University Franjo Pehar, University of Zadar Damir Kero, University of Zadar Members: Giuseppe Attardi, Università degli Studi di Pisa, Pisa, ITALY Pascal Costanza, Intel, Bruxelles, BELGIUM Marc Feeley, Université de Montreal, Montreal, CANADA Scott McKay, Google, U.S.A.

[parenscript-devel] help: question about eval-when usage
by Canhua 21 Jan '12

21 Jan '12

I am reading codes of paren-util. I find that it use "eval-when" inside defpsmacro. But I don't find that parenscript reference says eva-when is supported. As I understand, defpsmacro should expand into a valid parenscript code. Does parenscript support eval-when that although doesn't appear in reference. Thanks.

[parenscript-devel] create object bug ?
by Canhua 13 Jan '12

13 Jan '12

I found that (ps ([] (create :f 1))) yields to "[[create, 'f', 1]];" while changing "[]" to "list" yields expected result. Is that a bug? Best regards.

I use alisp (ANSI-compliant) lisp exclusively for these tests. Cheers, r P.S.

[parenscript-devel] Function application and variable renaming
by Scott Bell 07 Jan '12

07 Jan '12

PS appears not to support Lisp-1-style function application in the presence of variable renaming: (ps (let ((a 10)) (let ((a (lambda () 17))) (a)))) => "(function () { var a = 10; var a1 = function () { return 17; }; return a(); })();" If I use FUNCALL, or even FLET instead of LET, the correct code is generated. There's obviously some Lisp-2 action going on in PS, but unless I'm mistaken it seems like both forms can be supported. Scott

[parenscript-devel] test failure on Allegro
by Anton Vodonosov 06 Jan '12

06 Jan '12

Hello. I am running the tests of some CL libraries, including parenscript. You may find the results here: http://common-lisp.net/project/cl-test-grid/pivot_lib_ql-lisp.html. The OK/FAIL links refer to the library test logs with the failure details. As you may see, parenscript fails on Allegro: ; While compiling (:TOP-LEVEL-FORM "package.lisp" 54) in /home/rpg/lisp/cl-test-grid/quicklisp/dists/quicklisp/software/parenscript-2.3/src/package.lisp: Unhandled ERROR is signaled: There is no readtable named :PARENSCRIPT. Best regards, - Anton
