Apologies for the multiple postings. PAPER SUBMISSION DEADLINE EXTENDED 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 "Interoperability: 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: February 15th 2012: submission deadline (extended deadline) March 7th 2012: acceptance results April 30th 2012: Conference opens Program Commitee.

[cffi-devel] Error on ABCL: Unrecognized keyword argument :CONVENTION
by Anton Vodonosov 26 Jan '12

26 Jan '12

Hello. When I run the following command: java -cp jna.jar;C:\Users\anton\unpacked\abcl\abcl-bin-1.0.0\abcl.jar org.armedbear.lisp.Main --batch --eval "(ql:quickload :drakma)" an error occurs: Armed Bear Common Lisp 1.0.0-svn-13663 Java 1.6.0_26 Sun Microsystems Inc. Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.967 seconds. Startup completed in 3.725 seconds. Loading C:\Users\anton\.abclrc completed in 17.21 seconds. To load "drakma": Load 1 ASDF system: drakma ; Loading "drakma" .............. Caught PROGRAM-ERROR while processing --eval option "(ql:quickload :drakma)": Unrecognized keyword argument :CONVENTION I think it's cffi error (cffi is the only library having the :convention in source code). As you see in my command line, i load drakma. Drakma depends on cffi via cl+ssl. If I do (ql:quickload :cffi) it works, but I assume the error happens during macro-expansion of some CFFI macro, that's why loading is not enough, some code using cffi should be loaded too. Best regards, - Anton

[cffi-devel] Add complex aggregate objects support
by Клочков Роман 22 Jan '12

22 Jan '12

I try to make smart struct support in my project. It works. Now i can have foreign struct in lisp as lisp structures (defclass/defstruct). The only problem for me is mem-ref. When there is an array of structs, I need to use something like cffi::aggregatep to set fact, that struct are positioned in row, not pointers to them. But in that case I cannot set translator, because in cffi::mem-ref 110 (if (aggregatep ptype) 111 (inc-pointer ptr offset) 112 (let ((ctype (canonicalize ptype))) 113 #+cffi-sys::no-long-long 114 (when (or (eq ctype :long-long) (eq ctype :unsigned-long-long)) 115 (return-from mem-ref 116 (translate-from-foreign (%emulated-mem-ref-64 ptr ctype offset) 117 ptype))) 118 ;; normal branch 119 (translate-from-foreign (%mem-ref ptr ctype offset) ptype))))) Can we change (inc-pointer ptr offset) to (translate-from-foreign (inc-pointer ptr offset) ptype) ? If it is really pointer it remains unchanged, but if translate-from is overrided for particular type one can get any information out, not just pointers. -- Клочков Роман

[cffi-devel] Unit tests failures on different lisps
by Anton Vodonosov 06 Jan '12

06 Jan '12

Hello. I am running tests of some most often downloaded CL libraries, including CFFI. So far CFFI was only tested on Linux. It has Linux, has different number (of expected and unexpected) failures on different Lisps. The results may be found here: http://common-lisp.net/project/cl-test-grid/pivot_ql-lib_lisp.html Clicking the ok/fail status refer to the test logs with the failures details. Best regards, - Anton

Re: [cffi-devel] CFFI and Allegro common lisp
by Luís Oliveira 05 Jan '12

05 Jan '12

Hello John, git blame says you sent us a patch to add long-long on Allegro on 64-bit platforms. Robert says that isn't quite working. Do you have any recollection of any limitations of this long-long support or something like that? Meanwhile, I'll revert the patch: <https://github.com/cffi/cffi/commit/80a06643361af383cadcbb7232ba3d73b828a96d> unless you have some objection since I don't have access to a 64-bit ACL.

[cffi-devel] Linking CL to fortran-77 via cffi
by Mirko Vukovic 04 Jan '12

04 Jan '12

Hello, Several projects (lla, blapack among them) link common lisp (cl) to fortran 77 (f77)code. Unfortunately, being totally unfamiliar with cffi, I was having trouble using those packages to learn how to link cl to other f77 code. To learn more about calling f77 code from CL, I assembled a bunch of simple examples (using cygwin+clisp+gfortran).to show how to pass values of various types to f77. I have put up the examples on https://github.com/mirkov/cffi-f77. I tried to add enough documentation to make the package easily understandable. I hope this proves useful to others. I would appreciate comments regarding errors and improvements. And, as always, thanks for cffi :-) Mirko

[cffi-devel] 64bit hosts without multilib
by Elias Pipping 03 Jan '12

03 Jan '12

Hi, the file tests/GNUmakefile currently contains the lines ifeq ($(ARCH), x86_64) SHLIBS += libtest32$(SHLIB_EXT) libtest2_32$(SHLIB_EXT) endif As a result, building with -m32 will be tested on 64bit hosts. This can only work on multilib hosts, however; for others the test will fail. Best regards, Elias Pipping
