Subject: bug#33532: 26.1; set-window-configuration does not restore display start
Date: Tue, 27 Nov 2018 23:11:21 +0100 [thread overview]
Message-ID: <87efb62mt2.fsf@metalevel.at> (raw)
In "emacs -Q", please evaluate the following form:
(let ((buf (get-buffer-create "buf")))
(switch-to-buffer buf)
(erase-buffer)
(dotimes (x 10)
(insert (format "x is %s\n" x)))
(recenter 3)
(sit-for 1)
(let ((conf (current-window-configuration))
(ws (window-start))
(str (with-current-buffer buf (buffer-string))))
(with-current-buffer buf
(erase-buffer)
(insert str))
(set-window-configuration conf)
(sit-for 1)
(message "window-start: %s vs. %s" ws (window-start))))
This shows that after set-window-configuration, even though the buffer
content is the same as at the time the configuration was obtained, the
value of (window-start) differs from before: After the window
configuration is set, (window-start) is 1. I expect it to be 50 (i.e.,
the value at the time the configuration was obtained), because the
documentation of current-window-configuration states:
This describes ... for each ... buffer, where display starts ...
If possible, could you please consider restoring window-start to the
exact same position? Thank you very much!
