Perhaps this script will illustrate:
let s = '-2 3-4-5-6-7-8'
let p = '\([0-9-]\@<!-\)\?\d[0-9]*'
let [start, end] = [0, 0]
while 1
let start = match(s, p, end)
let end = matchend(s, p, end)
if start == -1
break
endif
echo s[start : end-1]
endwhile
I get:
-2
3
-4
-5
-6
-7
-8
It would appear that using the third parameter to match() and matchend(), the
match is done as if on a substring starting at the parameter, so the look
behind assertion does not see what's there in the original string.
This is unlike searching in a buffer; the look behind assertion does look
behind the start position of the search. Rameo, is this what you're getting at?
