Counting text from point in the string

I want to count text but want to start it from a dash in the text. Only thing consistant in the test is the dash.

I know strlen to count but do I convert to a list then use member?

examples of string

Cooler - ...

Freezer - ...

Freezer Refrigeration - ...

If you're trying to count the number of characters after a - in a string

here's one way... if a - isn't in the string you'll get an error

_4$ (- (strlen "Cooler-123")(vl-string-position (ascii "-") "Cooler-123" 0 ) 1)
3

(defun foo (s)
 (vl-string-left-trim
   " "
   (substr s
           (+ 2
              (cond ((vl-string-search "-" s))
                    (-1)
              )
           )
   )
 )
)

(foo "alan - thompson") -> "thompson"

(foo "alan") -> "alan"

nice one guys!

Not dissimilar to Alans...

(defun foo ( s )
 (vl-string-left-trim " "
   (vl-list->string
     ( (lambda ( l ) (cond ( (cdr (member 45 l)) ) ( l ))) (vl-string->list s) )
   )
 )
)
