I tried to rewrite the code in different ways but its still working correctly but without any result so can any one please help me to rewrite it correctly?
Don't use an initial-fact pattern in your rules. The initial-fact is
no longer supported in CLIPS 6.4. Just leave the conditions of the
rule empty and it will work in both version 6.3 and 6.4.
The protein-advice defrule expects a protein-needed fact but a
daily-protein fact is asserted by your other rules.
The carbohydrate-advice defrule expects a carbohydrate-needed fact but a daily-carbohydrates fact is asserted by your other rules.
The fiber-advice defrule expects a fiber-needed fact but no fiber
related facts are asserted by any of your rules.
The calcium-advice defrule expects a calcium-needed fact but a daily-calcium fact is asserted by your other rules.
Your other rules that print results have similar issues.

I am trying to retract a deftemplate fact but when I do this CLIPS keeps saying I have to first declare the deffunction yet it is the appropriate deftemplate.What seems to be the problem?
I have attached the related code:
I get this error:

What seems to be the problem?

In the RHS of the input rule you state:
?d <- (Agriculture(crop ?a) (weed ?b) (organic-matter ?c))
This is interpreted as "Run function Agriculture and bind its results into ?d".
What you probably are trying to do is:
(bind ?d (assert (Agriculture (crop ?a) (weed ?b) (organic-matter ?c))))
I have a task, write a program to count the number of repetitions of a word in the list.
I just started learning the clips so I do not know many things.
I wrote the code, but unfortunately it does not work, what could be the error?

I really hope the same way that you explain in detail what the error is and maybe tell me another version of the implementation of the code.
P. S. I implemented another version of the program - the search for the number of repetitions of words in the sentence. This code also does not work.

I really hope for your help in understanding the clips.
P. P. S. Sorry for my english
I can offer here this option. This has many shortcomings, but as an example this will suitable.

I'm trying to increment a defglobal variable (symcount) by 1 if the user defines that they have pain by using the (read) function

(defrule AnsInc

the increment must only happen of the user presses "y"
otherwise the increment must not happen.

Morning, Excuse the silly question but I am busy building a expert system much like the "21 Questions" game that uses questions asked to the user in order to determine the right dog for them. The expert system is coded in CLIPS / .CPS language and one of the requirements I am looking to include is that when the user is asked a yes/no question they are required to input "y" or "n".
In all the resources we have been taught we have only been tough number validation and not a specific character validation and I cannot find any resources that do this either.
This is an example of the number validation I did in order to ensure they input a valid number on one of my questions
(defrule test-integer
(number-in ?number&:(integerp ?number))
=>
(printout t ?number "is valid"
(defrule test-non-int
?number-address <- (number-in ?number&:(not (integerp ?number)))
=>
(printout t ?number " not valid int" crlf)
(retract ?number-address))
This is how you'd do it using rules:
CLIPS>
(defrule test-response
(response-in ?response&y|n)
=>
(printout t ?response " is valid" crlf))
CLIPS>
(defrule test-non-response
?response-address <- (response-in ?response&~y&~n)
=>
(printout t ?response " not valid response" crlf)
(retract ?response-address))
CLIPS> (assert (response-in xyz))
<Fact-1>
CLIPS> (run)
xyz not valid response
CLIPS> (assert (response-in n))
<Fact-2>
CLIPS> (run)
n is valid
CLIPS>
I'd suggest using a function that only accepts correct responses:
CLIPS>
(deffunction ask-question (?question $?allowed-values)
(printout t ?question)
(bind ?answer (read))
(if (lexemep ?answer)
then (bind ?answer (lowcase ?answer)))
(while (not (member ?answer ?allowed-values)) do
(printout t ?question)
(bind ?answer (read))
(if (lexemep ?answer)
then (bind ?answer (lowcase ?answer))))
?answer)
CLIPS> (ask-question "Continue? " y n yes no)
Continue? k
Continue? l
Continue? ye
Continue? YeS
yes
CLIPS>
What i figured out was to link the answer from the one defrule to that of another defrule first to check if the answer was valid and then again if that answer was valid to link it to the correct defrule then that will proceed with the next question.
Code is from my own Expert System:
(defrule Small-CoatType-Full
(Small-Coat f)
(person (name ?name))
=>
(open "result.txt" result "a")
(printout result ?name " Likes Smaller, Fury Dogs" crlf)
(close result)
(printout t "Would you like a low energetic(l) or high energetic(h) breed?" crlf)
(assert (Small-Energy-Level(lowcase(read)))))
(defrule Small-Energy-Level-Wrong
(Small-Energy-Level ?var &~l&~h)
=>
(printout t crlf "Plesae Only Choose (l) or (h)")
(assert (Small-Energy-Level (lowcase(read)))))`
I am trying to return a message if the user types in a value within certain range. Is this possible on CLIPS? In addition the system should only accept values in increments of 10.
If the user types in a number less or equal to 10 it should say "A"
If the user types in a number greater than 10 and less than 40 it should say "B"
- so it should only accept values 10,20,30,40
This is the code I have so far:
(defrule b-a1
(b-a "a")
=>
(bind ?reply (get-text-from-user "How many points did you achieve?"))
(assert (b-a1 ?reply )))
(defrule b-a2
(b-a1 <= 10)
=>
(assert (conclusion "A")))
(defrule b-a2
(10 < b-a1 < 40)
=>
(assert (conclusion "B")))
Any ideas on how I can get this working?
CLIPS>

=>
(printout t "How many points did you achieve? ")
(bind ?reply (read))
(assert (b-a1 ?reply )))
