Subject: regex nirvana - near miss
Date: Thu, 26 Jun 2014 10:18:24 -0500 [thread overview]
Message-ID: <27747b$8snl6c@ironport10.mayo.edu> (raw)
Often I wish to match a string not followed by another string, e.g.
"abc" without "def" following. I had a glimpse of nirvana today when I
thought of trying this RE: abc\(def\)\{0\}, but alas it was not to be
had as it gets optimized and just matches "abc". It is tedious to use:
abc\([^d]\|d[^e]\|de[^f]\), especially when the second string gets longer.
