mhupp Posted June 5, 2023 Posted June 5, 2023 (edited) Tech you don't need to split up numbers and letters. But I just liked how it looked. so you don't really even need to test for anything. The lisp below just puts each char in brackets and works the same. ;;----------------------------------------------------------------------------;; ;; Generate a text search that ignores Case Senesitivity. ;; saunambon654, Lee Mac, mhupp ;; https://www.cadtutor.net/forum/topic/39880-case-sensitivity/#comment-618863 ;; (ssget "X" (list '(0 .

If your string is long (hundreds of letters) it will be effect to speed calculation. Quote
Lee Mac Posted June 5, 2023 Posted June 5, 2023 Here's another way to write it - (defun casesensitivity ( s ) (vl-list->string (apply 'append (mapcar '(lambda ( a b ) (if (= a b) (list a) (list 91 a b 93))) (vl-string->list (strcase s)) (vl-string->list (strcase s t)) ) ) ) ) As for combinations, maybe something like this - (defun combinations ( s / foo ) (defun foo ( u l ) (if (cdr u) (append (mapcar '(lambda ( x ) (cons (car u) x)) (foo (cdr u) (cdr l))) (mapcar '(lambda ( x ) (cons (car l) x)) (foo (cdr u) (cdr l))) ) (list u l) ) ) (mapcar 'vl-list->string (foo (vl-string->list (strcase s)) (vl-string->list (strcase s t)) ) ) ) _$ (length (combinations "floor")) 32 3 Quote
