Subject: Re: Bug: Hi-lock-mode doesn't highlight regexp re-builder vets
Date: Tue, 10 Jul 2007 19:10:06 -0500 [thread overview]
Message-ID: <7wr6nfiyw1.fsf@ece.lsu.edu> (raw)
In-Reply-To: <C2B3C393.15CF%denbuen@sandia.gov> (Denis Bueno's message of "Fri\, 06 Jul 2007 10\:01\:55 -0600")
Not a bug. The text in the re-builder buffer has '\' escaped (to
'\\'), for use as string value (literal?). The value expected by
highlight-regexp when reading from the minibuffer is the regexp
without escaping of backslashes.
The following would work:
C-x w h 09[:]\(\(28\)\|\(29\)\|\(30\)\)
