I have this function which calculates some value based on multiple slots of multiple multifield facts.
Because quite some slots are involved and all of them are needed in the function I was thinking if I could pass a whole fact to a function and access its slots in it,
like so:
(deftemplate a-fact
(slot id)
(slot name)
(slot ...)
...
)
(deffunction a-funciton (?factadr)
(switch ?factadr:name
(case bla then ...)
)
(return ?calculated-value)
)
(defrule a-rule
?factadr <- (a-fact (id ?i))
=>
(if (> **(a-function ?factadr) 20) then ... )
)
I saw this ?fact-adrres:slot-name in this example and thought it will work but it doesn't. So, is it possible and how to do it?
(bind ?facts (find-all-facts ((?f attribute))
(and (eq ?f:name wine)
(>= ?f:certainty 20))))
Clips 6.3 is used.
Use the fact-slot-value function.

(deftemplate a-fact
(slot id)
(slot name))

(defrule a-rule
?f <- (a-fact)

(printout t (fact-slot-value ?f id) " " (fact-slot-value ?f name) crlf))
CLIPS> (assert (a-fact (id 3) (name x)))
<Fact-1>
CLIPS> (assert (a-fact (id 7) (name y)))
<Fact-2>

I want to insert two variable values in a string slot of a template but I am having errors. I know about the multislot but it is giving me a dictionary output like this:
('1.', '§ 2 is amended as follows:')
But I want like this:
1. § 2 is amended as follows:
https://www.csee.umbc.edu/portal/clips/usersguide/ug4.html In this link it is written that we can assign many variables to one slot in assert but when I do this I am getting errors. I am importing clips in python in VSCode. Thank you in advance and I hope I am explaining the issue properly.
These are the rules:
(defrule createlist1
(declare (salience 91))
(ROW (counter ?A)
(ID ?id)
(Text ?t)
(Path "//Document/Sect[3]/Sect/L/LI/Lbl"))
=>
(assert (Temp (tempvalue "YES")
(temptext ?t))))
(defrule createlist2
(declare (salience 91))
(and (Temp (tempvalue "YES")
(temptext ?t))
(ROW (counter ?A)
(ID ?id)
(Text ?text)
(Path "//Document/Sect[3]/Sect/L/LI/LBody/ParagraphSpan")))
=>
(printout t " value is " ?t ?text crlf)
(assert (WordPR (counter ?A)
(structure ?id)
(tag "list")
(style "list")
(text ?t ?text))))
These are the templates:
template_WordPR = """
(deftemplate WordPR
(slot counter (type INTEGER))
(slot structure (type INTEGER))
(slot tag (type STRING))
(slot style (type STRING))
(slot text (type STRING)))

(slot temptext (type STRING)))
"""
template_string = """
(deftemplate ROW
(slot counter (type INTEGER))
(slot ID (type INTEGER))
(slot Text (type STRING))
(slot Path (type STRING)))
"""
This is the error I am getting:
ERROR: The single field slot 'text' can only contain a single field value.
You can't put multiple values into a slot without declaring it as a multislot, but if you're dealing with strings you can concatenate the values before assigning them to the slot.

I 've grateful if you could helpme.
On the right hand side of rule R17 you assert
Electrocardiograma (estado APTO)
but during this assert all the constraints for Electrocardiograma in all the rules are evaluated. This includes rule R16 wheren this Electrocardiograma's frecuenciaCardiaca is compared to 60. But this slot has not been set, so it remains at nil. Therefore the comparison using <, the numeric comparison operator, is bound to fail.
(Note: Don't use 59 and 60. It is much clearer to use <60 and >=60.)
If you really want to assert another (!) Electrocardiograma fact you should provide at least safe values for all slots. (It is more likely that you want to modify the Electrocardiograma fact to hold the outcome of )
I have a class A which consists of two subclasses B and C. Class B has three instances, while C two. Can I write a JessTab rule which will count all implicit instances of A i.e. give me 5?
Mapping class A in Jess:
(mapclass http...#A)
Rule to count instances which gives me 0 since there are no direct instances of A:
Originally:
(defrule countAinstances
?c <- (accumulate (bind ?count 0)
(bind ?count (+ ?count 1))
?count
(object (ís-a http...#A))
)
=>
(printout t ?c " number of class A instances." crlf))
This doesn't count instances of subclasses of A.
Modified version:
(defrule countAinstances
?c <- (accumulate (bind ?count 0)
(bind ?count (+ ?count 1))
?count
(object (OBJECT ?x&:(instanceof ?x http...#A)))
)
=>
(printout t ?c " number of class A instances." crlf))
The following error appears:
Jess reported an error in routine instanceof while executing
(instanceof ?_20_x(0,2,-1) http...#A) while executing rule LHS (TEQ)
while executing rule LHS (TECT). Message: Class not found:
http...#A. Program text: ( defrule countAinstances ?c <- (
accumulate ( bind ?count 0 ) ( bind ?count ( + ?count 1 ) ) ?count (
object ( OBJECT ?x & : ( instanceof ?x http...#A ) ) ) ) = > (
printout t ?c " number of class A instances." crlf ) ) at line 20.
Nested exception is: http...#A
Access the object and rely on Jess' own function instanceof, not the protege slot is-a:
(object (OBJECT ?x&:(instanceof ?x A)))
Use the full class name if A isn't imported.
if you don't have the Java class name, you'll have to test for all classes and subclasses in that pattern, using an (or) function. Rather tedious.
Later
Seeing that is-a contains class references that can be compared to class names, this would be the simplest way of writing the rule:
defrule countAinstances
?c <- (accumulate (bind ?count 0)
(bind ?count (+ ?count 1))
?count
(object (is-a ?x&B|C))
)
=>
(printout t ?c " number of subclass instances." crlf))
The complete solution-rule is as follows:
(defrule countAinstances
?c <- (accumulate (bind ?count 0)
(bind ?count (+ ?count 1))
?count
(object (is-a ?x&:(or (= ?x B)(= ?x C))))
)
=>
(printout t ?c " number of subclass instances." crlf))
Similar to the compiler directive for constants in C, is there a way I can do the following in CLIPS?
#define INFINITY 1000000000
(deftemplate foo
(slot num (type INTEGER) (default INFINITY))
)
...
(defrule bar
(foo (num INFINITY))
=>
...
)
You can define a global variable and treat it as a constant:
CLIPS> (defglobal ?*INFINITY* = 1000000000)
CLIPS>
(deftemplate foo
(slot num (type INTEGER) (default ?*INFINITY*)))
CLIPS>
(defrule bar
(foo (num ?num&:(eq ?num ?*INFINITY*)))
=>)
CLIPS> (assert (foo))
<Fact-1>
CLIPS> (facts)
f-0 (initial-fact)
f-1 (foo (num 1000000000))
For a total of 2 facts.
CLIPS> (agenda)
0 bar: f-1

hello in clips i have this template:
(deftemplate cell(slot x)(slot y)(slot alive))
and this fact :
(start 1 1)
then i have this claus in the LHS :
?start<-(start ?x ?y)
and i want to get the variable ?a1
(cell (x (+ ?x 1) )(y ?y)(alive ?a1))
it seems that it's not allowed to add to the variable "(+ ?x 1)" so how
can i achieve what i want.
CLIPS> (deftemplate cell (slot x) (slot y) (slot alive))

(deffacts initial
