Re: [Ciao-users] Trouble getting started from source packages, SVN access?

Hi Ian, thanks for the kind words. > It also appears that the optimizing compiler is not packaged with > these source distributions, so I guess it's not surprising that it > would fail to compile. Correct. A lot of the issues you mention are related to the fact that we are currently at the same time moving from svn to git, moving all the repositories and the continuous integration system to new servers, and same time moving our servers to a new building --very brave! As a result we are not generating daily releases during the move and fixes are thus not being reflected. This move should be over soon however and things should get back to normal. > 1) Is there public (read-only) access to the source repository? Not currently, but we will set it up shortly for the new git repo. > 2) Have there been recent changes in trunk that may address > compilation issues for experimental features? Yes, we are always working on the system and there are always fixes (and bugs of course ;-)). In particular we have just fixed the CHR bug related to mutables that you pointed out. > 3) In the case of (2 and not 1), would someone be kindly enough to cut > a new source package based from the latest revision? Will do as soon as we can... > 4) Would you like me to provide more detailed info about the errors? Please do send them: they are most helpful.

Fwd: Problems with Java to Prolog interface
by Giacoma Monreale 31 May '13

31 May '13

Hello, we are using Ciao in the European project ASCENS and I need to interface Ciao with Java. In order to start and to understand how it is possible to do this, I tried to execute example0.pl, which is one of the proposed Java-to-Prolog interface examples. Unfortunately, when I start the example (trying to follow all the instructions of the readme.text file) something doesn't work. In particular, after the execution of the instruction goal.query() of the example0.java program, the execution does not proceed, in the sense that the client seems to wait something. I tried to understand the problem but without results. I am using Mac OS X version 10.8 and the last version of Java. I would like to ask you if you can kindly help me by giving some suggestions or hints about it. Best regards, Giacoma Monreale

(apologies for multiple copies) ----------------------------------------------------------- WLPE 2013 - CALL FOR PAPERS Workshop on Logic-based Methods in Programming Environments (satellite workshop of ICLP 2013) 24-25 August 2013 Istanbul, Turkey http://clip.dia.fi.upm.es/Conferences/WLPE13/ ----------------------------------------------------------- The workshop aims at providing an informal meeting for researchers working on logic-based tools for development and analysis of programs. In addition to papers describing more conceptual work on environmental tools, we solicit papers describing the implementation of and experimentation with such tools. We hope to attain the same friendly atmosphere as in past workshops, which enabled fruitful exchanges leading to joint research and subsequent publications. Areas particularly relevant to the workshop include: * static and dynamic analysis * debugging and testing * program verification and validation * code generation from specifications * termination and non-termination analysis * reasoning on occurs-check freeness and determinacy * frameworks and resources for sharing in the logic programming community * profiling and performance analysis * type- and mode analysis * shape, point-to and escape analysis * module systems * optimization tools * program understanding * refactoring * logical meta-languages Note that this list is not exhaustive and, if you are interested in taking part in the workshop but unsure if your work falls within its scope, do contact the organisers who will be happy to advise. The 23rd Workshop on Logic-based methods in Programming Environments will take place in Istanbul, Turkey, as a satellite workshop of ICLP 2013, the 29th International Conference on Logic Programming. This workshop will continue the series of successful international workshops on logic programming environments held in Ohio, USA (1989), Eilat, Israel (1990), Paris, France (1991), Washington, USA (1992), Vancouver, Canada (1993), Santa Margherita Ligure, Italy (1994), Portland, USA (1995), Leuven, Belgium and Port Jefferson, USA (1997), Las Cruces, USA (1999), Paphos, Cyprus (2001), Copenhagen, Denmark (2002), Mumbai, India (2003), Saint Malo, France (2004), Sitges, Spain (2005), Seattle, Washington USA (2006), Porto, Portugal (2007), Udine, Italy (2008), Pasadena, USA (2009), Edinburgh, UK (2010), Lexington, USA (2011), and Budapest, Hungary (2012).

by Gopal Gupta 26 May '13

26 May '13

Paper submission deadline is June 11, 2013. ============================================================ LOPSTR'13 23rd International Symposium on Logic-Based Program Synthesis and Transformation LOPSTR 2013 http://www.utdallas.edu/~gupta/lopstr Madrid, Spain, September 18-20, 2013 DEADLINES Abstract submission: June 4, 2013 Paper submission: June 11, 2013 ============================================================ The aim of the LOPSTR series is to stimulate and promote international research and collaboration on logic-based program development. LOPSTR is open to contributions in logic-based program development in any language paradigm. LOPSTR has a reputation for being a lively, friendly forum for presenting and discussing work in progress. Formal proceedings are produced only after the symposium so that authors can incorporate this feedback in the published papers. The 23rd International Symposium on Logic-based Program Synthesis and Transformation (LOPSTR 2013) will be held in Madrid, Spain; previous symposia were held in Leuven, Hagenberg, Coimbra, Valencia, Lyngby, Venice, London, Verona, Uppsala, Madrid, Paphos, London, Venice, Manchester, Leuven, Stockholm, Arnhem, Pisa, Louvain-la-Neuve, Manchester and Odense (you might have a look at the contents of past LOPSTR symposia). LOPSTR 2013 will be co-located with PPDP 2013 (International ACM SIGPLAN Symposium on Principles and Practice of Declarative Programming). Topics of interest cover all aspects of logic-based program development, all stages of the software life cycle, and issues of both programming-in-the-small and programming-in-the-large. Both full papers and extended abstracts describing applications in these areas are especially welcome. Contributions are welcome on all aspects of logic-based program development, including, but not limited to: * specification * verification * analysis * specialization * composition * certification * transformational techniques in SE * synthesis * transformation * optimisation * inversion * program/model manipulation * security * applications and tools Survey papers, that present some aspect of the above topics from a new perspective, and application papers, that describe experience with industrial applications, are also welcome. Papers must describe original work, be written and presented in English, and must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal, conference, or workshop with refereed proceedings. Work that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC chair in case of questions). Proceedings The formal post-conference proceedings will be published by Springer in the Lecture Notes in Computer Science series. Important Dates Abstract submission: June 4, 2013 Paper submission: June 11, 2013 Notification (for pre-proceedings): July 20, 2013 Camera-ready (for pre-proceedings): July 27, 2013 Symposium: September 18-20, 2013 Submissions must be formatted in the Lecture Notes in Computer Science style. They cannot exceed 15 pages including references but excluding well-marked appendices not intended for publication. Referees are not required to read the appendices, and thus papers should be intelligible without them. Full papers can be directly accepted for publication in the formal proceedings to be published by Springer in the LNCS series or accepted only for presentation at the symposium. After the symposium, all authors of extended abstracts and full papers accepted only for presentation will be invited to revise and/or extend their submissions in the light of the feedback solicited at the symposium. Then, after another round of reviewing, these revised papers may also be published in the formal proceedings. Authors should submit an electronic copy of the paper (written in English) in PDF or Postscript (Level 2). Each submission must include on its first page the paper title; authors and their affiliations; contact author's email; abstract; and three to four keywords. The keywords will be used to assist us in selecting appropriate reviewers for the paper. If electronic submission is impossible, please contact the program chair for information on how to submit hard copies. Papers should be submitted to the submission website for LOPSTR 2013.

call/n Argument Order
by Jan Burse 12 May '13

12 May '13

Dear All, I am using the following directive: ?- use_module(engine(hiord_rt)). I am expecting that I will then have call/n available as defined in the ISO TC2. But it seems that the arguments are not appended, but something else happens. I get: ?- call(f(p,q),r,s,t). 1 1 Call: user:f(r,p,q,s,t) ? But I would expect: ?- call(f(p,q),r,s,t). 1 1 Call: user:f(p,q,r,s,t) ? Bug or feature? Bye

Indirect predicate
by John McCulloch 10 May '13

10 May '13

I have code with a construct that appears repeatedly with only a small difference consisting of a different predicate call each time. I want to create a predicate that can take a predicate as an argument. Here is the generic predicate: array_def (_,[],[]) :- !. array_def(Type,[H|T],[H0|T0]) :- !,Type(H,H0), array_def(T,T0). array_def(Type,H,[H0]) :- Type(H,H0). Type is a variable predicate where H is an input and H0 is an output. An example is: value_literal(H,H0) :- number_literal(H,H0), !. value_literal(H,H0) :- string_literal(H,H0), !. value_literal(H,H0) :- boolean_literal(H,H0). So I want to declare something like this: value_literal_array(Arr,Arr0) :- array_def(value_literal(...,...),Arr,Arr0), ... I don't understand the description of call/2 in the manual. Is there a way to use that? If so, how? If not, how else can I do this? How would I include it in array_def and how would I Thanks, John -- View this message in context: http://old.nabble.com/Indirect-predicate-tp35368200p35368200.html Sent from the Ciao Prolog - Users mailing list archive at Nabble.com.
