I've searched for questions like this, but all the cases I found were solved in a problem-specific manner, like using !g in vi to negate the regex matches, or matching other things, without a regex negation.
Thus, I'm interested in a “pure” solution to this:
Having a set of strings I need to filter them with a regular expression matcher so that it only leaves (matches) the strings lacking a given substring. For example, filtering out "Foo" in:
Boo Foo Bar FooBar BooFooBar Baz
Would result in:
Boo Bar Baz
I tried constructing it with negative look aheads/behinds
(?<!regex), but couldn't figure it out. Is that even possible?
