Negated higher order variables not parsed?

Gorbag — Fri, 31 Aug 2012 19:50:06 -0000

Attempting to replicate the suggestion on page 57 of the book about an obstreperous agent, entering

+B <- !~B.

gives me an underline (i.e. a parse error) in the jEdit buffer. We've been struggling with other uses of negation on variables to the point we have had to implement an internal function .negate (A , B) just to get ~A (bound to B), e.g., to handle a response to queryIf. Seems like a bug, if the intention is to strongly support strong negation... (It's not just jEdit getting mad, if we load the code we get an error).

Thanks!

Directives not working

s1l3n0 — Mon, 12 Mar 2012 09:14:32 -0000

Hi everybody,
I tried to use directives, but I was not able to.
The example directive in Section 7 given by the book is not working,

The error I get, once I start the animation, is
--------------------------------------
[DirectiveProcessor] Error processing directive add_print("end of plan")
java.lang.NullPointerException

I tried to change to SACI infrastructure.
The error was then:

[DirectiveProcessor] Unknown directive add_print("end of plan")
--------------------------------------

Tried on Linux and Windows with the last jason..

while condition

Willem Timmers — Sun, 18 Sep 2011 17:35:19 -0000

From the API: "Implementation of while. While logical formula holds, the plan_body is executed."
The abortion of the while loop isn't true for suspended intentions. Thus the while loop in intentions which are suspended because of external actions/.wait action/other reasons aren't aborted.

Should that be? I can imagine that it gets aborted when the intention is resumed (after a external action), but then again the believes can already be changed back (and therefore missed by that intention).

As #3408087. But now with v1.3.6. I'm still getting errors:

Eclipse plugin 1.3.5

Willem Timmers — Mon, 12 Sep 2011 13:58:58 -0000

I'm sorry for the duplicate: #3408059

This is what happens when I install jason 1.3.5, Eclipse (Indigo Release), jdk 1.7.0, and the jason plugin for Eclipse 1.3.5 and follow the instructions at http://jasonplugin.wikidot.com/guia-do-usuario

The Eclipse console returns several errors, while running the same project in jEdit returns no errors:

mas2j: reading from file xxxxxx/Workspace/some_project\some_project.mas2j ...
mas2j: xxxxxx/Workspace/some_project\some_project.mas2j parsed successfully!
