Subject: RE: Apparent problem with looking-at?

Message-ID: <9E217BAD4019CE4095869023168429A9CCF91B@vulture.corp.resmed.org> (raw)

Richard,

I believe the problem was that when I originally coded this defun (some
years ago now) I had an incomplete and faulty understanding of some of the
elisp defuns I was using - in this case, it was looking-at :-).

The code should have been (As Kim Storm kindly pointed out in
gnu.emacs.bugs):

(looking-at (regexp-quote comment-start))

using this works perfectly well (and was what I originally intended :-)). I
suspect that the "bug" has existed in my code all of this time because I
rarely code in C and thus the particular fact that a C comment-start is
actually a regular expression meant that I never noticed the problem i.e. I
normally use this code snippet with other languages and thus other
comment-start definitions and was thusly (falsely) under the impression that
this code had only failed with Emacs 21.2.1 - my apologies :-).

Thankyou for your help, I fixed "my" problem :-)

Regards,
Peter

Would you please provide a complete self-contained test case
so that we can reproduce the problem and debug it?

    nil and never has in previous versions of Emacs. If I alter the code
snippet
    to (looking-at "/*") then it works (note the absence of the space after
the
    '*'). Also, if I place a space character at the start of the line i.e.

Note that "/*" is a regexp that matches zero or more slashes.
