Topic: working with (-4 "<not")

[Amsterdammed]

Hello everybody
I got used a bit to work with that kind of filters for my ss. But I'm not sure about the use of the "<not". In this example i want to exclude layer "WL$ and blocks with the name "LDT" and "LDS". But somehow it doesn't work. So i see i don't understanfd the thing in it whole working.

Code: [Select]

(SETQ FLT '(
(-4 . "<AND")
(-4 . "<NOT")
            (8 . "WL$*")
            (2 . "LDS")
            (2 . "LDT")
            (-4 . "NOT>")
            (-4 . "<OR")
                     (8 . "WL*");;;                     (-3 . "STABICAD")
(8 . "EL*")
                     (-4 . "OR>")
            (-4 . "AND>")
                     )
               )
   
(setq ssb (ssget "c" pt2 pt1 flt))

Thanks in Advance,

 Bernd

(setq flt '((8 . "WL[~$]*,EL*") (2 . "~LD[ST]*")))
(setq ssb (ssget "c" pt2 pt1 flt))

Evgeny,

I obviosly don't get it (busy day or just to stupid). I need all the Block names and the "U*" as valid, exept thoose two.

Probably, I have misunderstood you...

Code: [Select]

(wcmatch "U*" "~LD[ST]*") ; => T
(wcmatch "AAA" "~LD[ST]*") ; => T
(wcmatch "LD" "~LD[ST]*") ; => T
(wcmatch "LDA" "~LD[ST]*") ; => T
(wcmatch "LDS" "~LD[ST]*") ; => NIL
(wcmatch "LDSA" "~LD[ST]*") ; => NIL
(wcmatch "LDT" "~LD[ST]*") ; => NIL
(wcmatch "LDTA" "~LD[ST]*") ; => NIL

Looks like ElpanovEvgeniy example would do the job. There is a lot of untapped power in the WCMATCH characters.

Perhaps this will work for you.

Code: [Select]

(setq flt '((-4 . "<NOT")    ; ignore if the following is true
               (-4 . "<AND")   ; all that follow must be true
                 (8 . "WL$*")    ; layer WL$ plus anything other characters
                 (0 . "INSERT")  ; blocks only
                 (2 . "LDS,LDT") ; only names LDS or LDT
              (-4 . "AND>")
            (-4 . "NOT>")))

Completely the working code.

Code: [Select]

(setq flt '((8 . "WL[~$]*,EL*") (2 . "~LD[ST]*")))
Works equally

Code: [Select]

(SETQ FLT
'((-4 . "<AND")
    (-4 . "<NOT")
      (8 . "WL$*")
      (2 . "LDS")
      (2 . "LDT")
    (-4 . "NOT>")
    (-4 . "<OR")
      (8 . "WL*")
      (8 . "EL*")
    (-4 . "OR>")
(-4 . "AND>")
))

Thanks both of you,

since i gad not my brightest day yesterday I ended with something looking like CAB"s approach, was easier to understand for me. The WCmatch is indeed powerfull, i use it a lot but only in the simple way. I have to get familiar with the special symbols.

Thanks, Bernd
