Subject: 24.1; Macro Playback Fails When Buffer Scrolls
--text follows this line--
This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgement at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
***************
Create a file with many more lines than the buffer can display at once.
In my test, the buffer has about 500 identical lines like this:
123456789 0123456789 01234567890
Then place Point at line 1 column 1.
I recorded the keyboard macro that you see in Recent Input, which merely
moves point just past the first 9, then deletes it and puts an "x" in
its place for the first three lines. Then it puts a "y" for the next
three. Point is then moved to the start of the next line before the
macro is finished recording.
Play back the macro a few dozen times.
As Point keeps moving down, the buffer will need to scroll. When it
does scroll, Point will not return to the start of the next line.
This happens also in version 23.4.1 on Win 7 and on 23.2.1 on Windows XP.
I guess the workaround would be to conclude the macro with C-u 0 l.
I'm amazed that I've been using Emacs (with macros) for 12.5 years and
never noticed this before!
***************
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
c:/emacs-24.1/etc/DEBUG.

Set line-move-visual to nil, and Bob's your uncle.

line-move-visual didn't exist before Emacs 23. So most of those 12.5
years, the bug didn't exist, because the only behavior available was
the one you see when you set line-move-visual to a nil value.

Dear Eli:
Thank you so much for your helpful and quick reply, and also for your involvement in the mailing lists, which has helped me many times before.
Sorry about sending a bug report, especially using MS Outlook.
Peace.
