Subject: bug#39067: shell-command-dont-erase-buffer strange behaviour
Date: Fri, 10 Jan 2020 05:34:18 +0000 [thread overview]
Message-ID: <xfezhevkh7p.fsf@cs.unm.edu> (raw)
C-h v shell-command-dont-erase-buffer
C-h f shell-command
Cut to the chase with the test case:
(let ((shell-command-dont-erase-buffer 'beg-last-out))
(with-current-buffer (get-buffer-create "OUT")
(erase-buffer)
(shell-command "/bin/echo FOO" t)
(shell-command "/bin/echo FOO" t)))
The result (as expected) is a buffer named OUT with 2 lines FOO.
The same result is expected with the following code:
(let ((shell-command-dont-erase-buffer 'beg-last-out))
(with-current-buffer (get-buffer-create "OUT")
(erase-buffer)
(shell-command "/bin/echo FOO" "OUT")
(shell-command "/bin/echo FOO" "OUT")))
However in this case (and in some other cases) shell-command erases the
"OUT" buffer despite a non-NIL binding of
shell-command-dont-erase-buffer
(at least since emacs 25.2)
