Can you please give a hint what I should look for? Hi. I've just installed Ciao in an NT machine, with no problems. We need some more information to find what is the problem. Which version of Emacs are you using? Can you open a Windows shell in Emacs (just do M-x shell)? If no, it is possible that you are using a anti-virus software which is causing problems: see http://www.gnu.org/software/emacs/windows/ntemacs.html#anti-virus for a workaround. Can you start the ciao shell (go to the installation directory, and, under the 'shell' directory, start ciaosh by clicking on it)? In ciao mode (e.g., after opening a *.pl file), when you go to the Ciao/Prolog menu and, at the bottom, select "SET MODE DEFAULTS" and then "Set Ciao Prolog toplevel executable", does the path to the ciaosh.bat file appears? If so, can you start from an MS-DOS shell this ciaosh.bat file? I am forwarding this mail to the ciao-users list; others may have found this problem and know how MCL _____________________________________________________________________ E lengeege weth e smell nember ef vewels cen remeen quete expresseve.

predicate_property/2 in CIAO 1.0pl7
by Paulo Jorge Lopes de Moura 04 Jul '00

04 Jul '00

Hi, I need a way to find if a given predicate is dynamic, static or built-in. The Reference Manual lists the usual predicate_property/2 but does not enumerate the possible predicate properties. Can someone provide me with some more info or a possible solution? Thanks.

Long atoms
by Adam Cheyer 04 Jul '00

04 Jul '00

Hi, I've just discovered CIAO prolog and am quite impressed! I'm trying to port a series of programs from Quintus prolog to CIAO, and I think the most complicated part of the port will be related to maximum atom length: CIAO insists on a maximum of 512 characters, while Quintus (and I believe Sicstus) allow atom values up to 64K. The programs will send data among Quintus and CIAO processes using sockets, and I'm worried the limitation will break a lot of code. Would it be a good idea to look at changing this restriction inside of CIAO, or are there good reasons why 512 characters are as long at atoms should ever be in CIAO? Thanks, Adam

Please help!!!
by Jordi Sabater Mir 30 Jun '00

Hi people, here again with more problems. Look at this small program: ************************************** :- concurrent proceed/2. :- use_module(library(concurrency)). :- use_module(library(system)). :- use_module(library(random)). not(X) :- X,!,fail. not(X). repeat. repeat :- repeat. producer(N,0) :- display(end(N)),nl. producer(N,M) :- repeat, random(1,100,I), not(proceed(N,I)), <==== ???? display(proceed(N,I)), nl, asserta_fact(proceed(N,I)), M2 is M - 1, producer(N,M2). start(0). start(N) :- eng_call(producer(N,5),create,create), M is N - 1, start(M). ***************************************** This program starts N threads. Each thread calculates a random number. Then, if there is already a fact with this number fails and tries to recalculate another one. If not, asserts a fact with the number and the thread identifier. Each thread repeats this operation 5 times. If I run this program as it is, it doesn't work. The strange thing is that when I remove the marked line (<==== ????) then it works!!! Do you experiment the same behaviour? Anybody knows what's wrong? I'm using Ciao1.5p166 and Linux. Thanks in advance. ______________________________________________________________________________ _/ _/ _/_| Jordi Sabater Mir / _/ _/ _| IIIA - Institut d'Investigacio en Intel.ligencia Artificial _/ _/___| CSIC - Spanish Scientific Research Council _/ _/____| Campus Universitat Autonoma de Barcelona / _/ _| 08193 Bellaterra, Catalonia, Spain Ph.: +34 3 5809570 Fax.: +34 3 5809661 jsabater(a)iiia.csic.es http://www.iiia.csic.es ______________________________________________________________________________

Threads again
by Jordi Sabater Mir 28 Jun '00

28 Jun '00

I was trying the example that Manuel sent about communication between threads and, although the example itself doesn't work on my installation (any idea?) the ideas in the example were enough to implement what I needed. Thanks Manuel. Another question for people who are using Ciao-Threads in Linux. Why after using eng_call to create a new thread, Ciao creates a new process? Is it normal or perhaps am I doing something wrong? Thanks again. ______________________________________________________________________________ _/ _/ _/_| Jordi Sabater Mir / _/ _/ _| IIIA - Institut d'Investigacio en Intel.ligencia Artificial _/ _/___| CSIC - Spanish Scientific Research Council _/ _/____| Campus Universitat Autonoma de Barcelona / _/ _| 08193 Bellaterra, Catalonia, Spain Ph.: +34 3 5809570 Fax.: +34 3 5809661 jsabater(a)iiia.csic.es http://www.iiia.csic.es ______________________________________________________________________________

Communication between threads

Hi people, Do you know if there is possible to have information shared by two or more threads? How can threads communicate between them?

How to use Ciao with SQL ? where is the database mediator server ?
by Alain Radix 27 Jun '00

27 Jun '00

Hi everybody ... I just get the ciao system and as I read the manual, it look impressive to me . Nice prolog !!! But I plan to use it to access database and I don't find where is the 'database mediator server' I may use in the windows . Should someone help me to find how to make it work ???? I prefer unix than win and may be, another possible implementation should be made using Tclodbc - ODBC extension for tcl http://www.solagem.fi/~rnurmi/tclodbc.html Sorry for my poor english ... and thanks.

PiLLoW on Windows 95 web server: PWS or Apache or ??
by Michael D. Kersey 29 May '00

29 May '00

I have installed Ciao-Prolog and the PiLLoW libraries on a PC running Windows 95. I'd like to use the PiLLoW library to create forms and dynamic web pages. But I've been unable so far to determine how to configure the system to do so. Does anyone know how to configure Windows PWS (Personal Web Server) to run PiLLoW pages? I know that for example, to execute Perl CGI programs, it is necessary to add a Windows registry entry of Key Value ==== ============== ".pl" Perl.exe %s %s AFAIK the first %s corresponds to a perl file to be executed (e.g., myprog.pl) while the second corresponds to the passed incoming POST or GET information. In response, Perl.exe outputs (CGI output) data to the default output file handle, which is routed back to the web server and then to the browser. Perhaps with the proper settings a similar effect can be achieved with ciaoengine.exe or another of the ciao programs? One side effect of DOS commandline execution of a Pillow executable is creation of a file with the same name as the executable, but with the file extension of ".html". E.g., executing ciaoengine -C -b html_demo.cpx from the DOS commandline creates a file named "html_demo.html". In this respect, ciaoengine's behavior differs from that of perl.exe, which outputs the data to the DOS standard output file handle. Related questions: Can the Apache for Windows web server be configured to run PiLLoW pages? Is anyone using some other web server on Windows 95 to run PiLLoW pages?

Pillow and XML
by Jordi Sabater Mir 25 May '00

25 May '00

Hi all, Do you have any documentation or examples about how to use the XML capabilities in Ciao? (It doesn't matter if examples are not commented or documentation is in beta stage, I'm just looking for something to start) Thanks in advance. ______________________________________________________________________________ _/ _/ _/_| Jordi Sabater Mir / _/ _/ _| IIIA - Institut d'Investigacio en Intel.ligencia Artificial _/ _/___| CSIC - Spanish Scientific Research Council _/ _/____| Campus Universitat Autonoma de Barcelona / _/ _| 08193 Bellaterra, Catalonia, Spain Ph.: +34 3 5809570 Fax.: +34 3 5809661 jsabater(a)iiia.csic.es http://www.iiia.csic.es ______________________________________________________________________________
