Hi,
I've the problem that I want to start a new instance of yap from within yap using system/1. Therefor I was wondering whether it is possible to get the path to the current instance of yap.

Hi Ingo,
Actually, that's a difficult question, YAP doesn't support that but I think that other languages, like ocaml, do have support. So it should be doable.

So it > should be doable. Yes it is definitely possible. The simplest solutionis to just use argv[0], which seems to be not available to the yap-user. The problem is storing argv[0] requires changes to the yap sources (console/yap.c). as the command line arguments are far as I see it nowhere stored. In general I think it might be not the worst idea to provide all arguments to the prolog envrionment. Appareantly the calling process can apparently manipulate this. But still the following code would be in most cases (except yap is executed using non properly initiales the arg structure) output the right result: static int parse_yap_arguments(int argc, char *argv[], YAP_init_args *iap) { char actualpath[PATH_MAX + 1]; realpath(argv[0], actualpath); printf("> %s <-> %s\n",argv[0],actualpath); There are actually more general better working approaches like the code here http://www.koders.com/c/fidEC2463ED7BDAD5D8B6CBAF1020498F35D9B3EDD9.aspx but this also requires to have access to the argument 0. I included a hacked custom predicate based on that (only tested on a mac). Which would still require in some cases argv[0] (except for: Macos, cygwin, linux) Ingo > > Sorry for the delay :( > > Vitor > > On Wed, Oct 7, 2009 at 1:53 PM, Ingo Thon > <ingo.thon@...> wrote: >> Hi, >> >> I've the problem that I want to start a new instance of yap from >> within yap using system/1. >> Therefor I was wondering whether it is possible to get the path to >> the current instance of yap. >> >> >> Thanks ingo >> >> ------------------------------------------------------- >> Ingo Thon <ingo.thon@...> >> Dept. of Computer Science >> Katholieke Universiteit Leuven >> Phone: +32 16 32 7741 >> skype: ingo_thon >> web: http://www.cs.kuleuven.be/~ingo/ >> ------------------------------------------------------- >> >> >> >> Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm >> >> --------------------------------------------------------------------- >> --------- >> Come build with us!

Yap Read Buffer containing illegal characters
by Ingo Thon-2
::
Rate this Message:
It's probably more a convenience as it seems the problem is in my code.
The following code in a custom C++ predicate causes yap into an infinite loop (consuming 100% cpu time). parsed = YAP_ReadBuffer("/aa/a", &err); whereas parsed = YAP_ReadBuffer("'/aa/a'", &err); parsed = YAP_ReadBuffer("'aaa", &err); both work. It's just hard(er) to trace down as YAP_Term YAP_BufferToString(char *buf ) YAP_Term YAP_BufferToAtomList(char *buf ) both work.

Hi Ingo
YAP actually keeps around an Yap_argv and an Yap_argc which hold the original value of argc,argv. Would argv[0] work on win32? The Koders code is GPLed, so I can't include it in the main source :( Cheers Vitor On Thu, Oct 22, 2009 at 11:18 PM, Ingo Thon <ingo.thon@...> wrote: > > On 21 Oct 2009, at 01:13, Vitor Santos Costa wrote: >> >> Hi Ingo, >> >> Actually, that's a difficult question, YAP doesn't support that but I >> think that other languages, like ocaml, do have support.
