I know i can do something like ab[^c]+def which should match ab_blah_hi_blah_def but is there a way to do something like
ab(^hi)+def
which will exclude the word hi causeing ab_blah_hi_blah_def to fail? but not ab_blah_h_i_blah_def
You can use a negative lookahead to do something like this. The pattern
(?!foobar).matches every character, except the f in “foobar”.So to match every word but “hi”, you could use
^((?!hi)\w)+$.
