shorting list..

'("A3" "A11" "A5" "A1") can shorting? and how the lisp look like

 

(acad_strlsort '("A3" "A11" "A5" "A1"))

("A1" "A11" "A3" "A5")

Also hit the VLIDE help file and search for "list manipulation
functions" and vl-sort

i need like this ("A1" "A3" "A5" "A11") it's can?

 

is it always only A's (only one prefix letter)???
never ("A1" "A2" "A3" "B1" "B2" "B3")???
if it is always A, then it's simple, but if not, it's more involved
(defun alphaNumsort (strlist)
(print strlist)
(mapcar
(function
(lambda(st st2)
(strcat (substr st 1 1)(itoa st2))
)
);f
strlist
(vl-sort
(mapcar
(function
(lambda(s)
(atoi (substr s 2))
)
)
strlist)
'<
)

);m
);d
(defun test()
(setq testlst(list "A2" "A3" "A45" "A1" "A5" "A7" "A100" "A6" "A1000"))
(alphaNumsort testlst)
)

_$ (test)

("A2" "A3" "A45" "A1" "A5" "A7" "A100" "A6" "A1000")
("A1" "A2" "A3" "A5" "A6" "A7" "A45" "A100" "A1000")


but that *won't* work if you have
;(setq testlst(list "A3" "B4" "A5" "B1" "A1"))

 

Pad with leading zeros ???
"A03" "A11" "A05" "A01"
"A003" "A011" "A005" "A001"

 

in testlsp i add same more "B34" "B2" "B12" "C12" "C4" "C2" and so on....
but the adds element is not display

 

That's why I told you it wouldn't work with those cases, you'll have to
write differently if you don't only have a's. your example only had a's.
Like I said, if you have more than one prefix letter this will not work, but
you might be able to figure out how to get it to work with the other letters
by seeing how this works
hint vl-sort is the culprit cause it *sometimes* discards duplicate values
so you have to sort yours a's and b's and c's separately, get it?
