[slime-devel] [ELS 2012] European Lisp Symposium 2012, Zadar, Croatia; call for papers
by Marco Antoniotti 17 Nov '11

17 Nov '11

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. • Kent Pitman, Hypermeta, U.S.A. • Christophe Rhodes, Department of Computing, Goldsmiths, University of London, London, UNITED KINGDOM • Robert Strandh, LABRI, Université de Bordeaux, Bordaux, FRANCE • Didier Verna, EPITA / LRDE, FRANCE -- Marco Antoniotti

Does anyone know how to do it? To use some combined index of hyperspec + other libraries?

[slime-devel] :charpos in swank-fancy-inspector vs :position in slime-ed
by Anton Kovalenko 11 Nov '11

11 Nov '11

Hello SLIME developers, Fancy-inspector module provides a feature that I tried to use today: for a stream object, it proposes to visit a file and go to current stream position. Unfortunately, it doesn't work in current SLIME. In swank-fancy-inspector.lisp, make-pathname-ispec passes a :charpos keyword, while in slime.el, slime-ed expects :position. I assume there's a real problem, not just an argument name incompatibility: for common CL implementations, CL:FILE-POSITION is measured in bytes, and slime-ed (that ends up in goto-char) expects character. Assuming unibyte encoding and passing :position argument from fancy inspector makes this feature useful most of the time, though. I'm unsure where the real problem (octets-vs-characters) should be fixed; a problem with argument names looks like a separate one, because what's passed in :charpos is a byte offset. -- Regards, Anton Kovalenko <http://github.com/akovalenko/sbcl-win32-threads/wiki> +7(916)345-34-02 | Elektrostal' MO, Russia

[slime-devel] New wire format
by Helmut Eller 08 Nov '11

08 Nov '11

I just committed changes to the wire format. The new format is defined on bytes and not characters. Counting characters was problematic, especially with Lisps that use UTF16 internally (Allegro, CMUCL, JVM based Lisps). Emacs counts the length of strings in Unicode code points, while in UTF16 a single code point may occupy either 1 or 2 indexes (code units) and so CL:LENGTH may return something different as Emacs expected. For the same reason we can't use READ-SEQUENCE to read a specified number of code points. The new format looks so: | byte0 | 3 bytes length | | ... payload ... | The 3 bytes length header specify the length of the payload in bytes. The playload is an s-exp encoded as UTF8 text. byte0 is currently always 0; other values are reserved for future use. Robert Brown said he'd like to use compression, so byte0 might come in handy. The change breaks backward compatibility. When upgrading, make sure that both Lisp and Emacs use the new format. I did some light testing with most of the backends and provided a portable version for the utf8 encoding/decoding. I didn't test SCL and CormanCL. Third party backends, for Clojure etc., are obviously broken now. So if you need those, wait until somebody fixes them and the dust has settled. Helmut

[slime-devel] Shutting down Swank within an Image.
by Andrew Myers 07 Nov '11

07 Nov '11

So I've been looking into the problem of restarting a lisp image saved from Slime. It appears to me that Swank is still blocked on the socket listening for connections in the restarted image in some cases (I'm not sure why it's inconsistent). As a result when the image is restarted it's stuck listening on a connection that will never receive data and can't execute the Swank initialization process to connect to the new socket which Slime has chosen. I was thinking that I would implement swank-backend:save-image to shutdown Swank before dumping the image (or possibly have the restart function shutdown any existing Swank processes) so there's nothing in the way of Swank being re-initialized when the image is loaded again. (Does this sounds like a reasonable thing to do?) I'm not sure how to do this though, there only seem to be methods for shutting down the Swank server, not individual connections. Looking at other implementations of save-image wasn't very illuminating so I seem to be missing something. It looks like the connection struct and the *connections* defvar might have what I need in it, but there is only sanctioned access to the most recently opened connection via `default-connection`. Presumably I would need to close _all_ *connections*? Can anyone point me in the right direction? Thanks, Andrew
