Idea/Question: Logical combinations matching on single line

[just-joshing]

Is there a way to scope logical combination matching to the same line?

I want to match a pattern but only if another pattern doesn't match on the same line. So I want a logical combination like (!A & B) where the expression is true if A and B are on separate lines or A doesn't appear at all, and false if A and B occur on the same line.

Thus far from my experimentation it seems logical combination just operates on the entire stream of content which means instead I have to write logic to capture the start lines of results for two patterns and compare them all to see how they line up.

Thanks!

I don't think we can perfectly handle this kind of behavior at the moment, unless you scan each line separately. We may think about how to support this feature in the future.
