Hi!
Look at the following two functions that I happened to write today:
(deffunction str-contains (?whole ?part)
(integerp (str-index ?part ?whole)))
(deffunction str-contains-ignore-case (?whole ?part)
(str-contains (lowcase ?whole) (lowcase ?part)))
str-contains checks to see if ?whole contains a substring ?part. The
integerp predicate function is needed becaus str-index either returns an
Integer (i.e., ?part's position in case ?whole contains ?part) or FALSE (in
case ?whole does not contain ?part).
You would use these functions as follows:
(defrule your-rule
(row (name ?name&:(str-contains ?name "new")) (value ?b))
=>
(printout t "List: " ?b crlf))
Greetings
Thomas

Hello All
I am new in Jess/Lisp and I am faced to solve such problem:
This is simplified example:
>>>>>>>>>>> code
(deftemplate row (slot name) (slot value))
(assert (row (name new) (value 1)) )
(assert (row (name news) (value 1)) )
(defrule list (row (name new) (value ?b)) => (printout t "List:" ?b crlf
))
(run)
>>>>>>>>>>>>>> code
I now need to list each row , where name STARTS with or CONTAINS the word
"new".
This example lists only words exactly maching name "new".
Does anybody have any idea how to do it ?
Thanx,
Laco Skokan.
