I mastered most of regular expressions. Only with the “non

lines containing Level.FINE — but not those who have been

/\C\v(\/\/)@!.{-}<Level\.FINE.{0,2}>/
The @! is supposed to not match - but it still does. And I
don't even know why.
You don't give the text you're trying to match against, but
sometimes turning on 'hls' can help you see why it's not matching
what you think. In your case, I _suspect_ that it doesn't match
starting at the "//", but that the match actually begins before
or after the "//" depending on the line because the @! merely
asserts that the "//" can't match at the starting point of the
match (it could match before/after). To get the expression you
want, I'd use
/^\%(\%(\/\/\)\@!.\)*Level\.FINE.\{0,2}>/
which asserts that you're looking for "Level.FINE" only where
"//" doesn't match at every position preceding it.
