Emacs info file

09 Aug '01

Hi! I have just installed Ciao 1.7p115. Everything seems to be working except a small glitch in info. When I look at one of the index pages (for example "Predicate/Method Definition Index") there are no cross references (links) defined. I cannot "hyperjump" from an index entry to the place it refers to. The stand-alone info behaves the same as from Xemacs. As a side effect (I think), when I use "C-C TAB" (ciao-help-on-current-symbol) I end up at the index page, not the description of the symbol. I would apreicate some help and possibly a "precompiled" ciao.info which you know works. Regards, Lars Erik PS. The librowser is extremly useful!! -- /***************************************** Lars Erik Röjerås Leonis Solutions AB Myrtenvägen 2 176 74 Järfälla Sweden Mobile: +46 (0)705 58 90 08 Fax: +46 (0)8 583 605 22 rojeras(a)leonis.se http://www.leonis.se *****************************************/

How to use variables as head ?
by Roel Wuyts 08 Aug '01

08 Aug '01

Hello, I have been using ciao for some time now, and this time I'm really stuck :-) I would like to use a variable in a head (as I used to do in WinProlog, for example). The problem is I cannot get it to compile, so I guess that I'm forgetting some switch or doing something completely stupid... Specifically, this is the rule I want to define: traverseComponent(Environment, Process, Component) :- Process(Component, Environment). Resulting in the following compile error: ERROR: (lns 408-411) syntax error: , or ) expected in arguments traverseComponent ( Environment , Process , Component ) :- call ( Process ** here ** ( Component , Environment ) ) . } -- Roel Wuyts Software Composition Group Roel.Wuyts(a)iam.unibe.ch University of Bern, Switzerland Board member of the European Smalltalk User Group: www.esug.org

Perl foreign interface
by Lars Erik Röjerås 07 Aug '01

Dear Ciao team! Thank you for a very good and feature rich prolog implementation. Have you considered implementing a foreign interface from Perl to Prolog? I guess it could be done very similar to the Java interface, to let the two environments communicate through a socket. Potentially a lot of the Prolog side code could be reused too, it seems to be quite generic. Regards, Lars Erik -- /***************************************** Lars Erik Röjerås Leonis Solutions AB Myrtenvägen 2 176 74 Järfälla Sweden Mobile: +46 (0)705 58 90 08 Fax: +46 (0)8 583 605 22 rojeras(a)leonis.se http://www.leonis.se *****************************************/
