I have tried using that function, but again, how do I get the last
buffer?
As when I put the function `rcd-last-async-buffer' into
`buffer-list-update-hook' with:
(add-hook 'buffer-list-update-hook 'rcd-last-async-buffer)
then from the function, when I invoke `M-& ls RET':
(defun rcd-last-async-buffer (&rest args)
(let ((last-buffer (last-buffer))
(current-buffer (current-buffer)))
(message "Last buffer: %s, current buffer: %s" last-buffer current-buffer)))
I get this message:
Last buffer: *Completions*, current buffer: *Messages* [2 times]
and I was inspecting `&rest args' and did not get any variables
sent. My expectations were different, for example, that the hook would
give me the buffer name at least through a function invoked, or
alternatively by sending it as argument.
If I cannot find last buffer created by M-& then I would need to list
buffers and again, how do I find the last one created if they are not
created one after the other really... the next empty number will be
filled with new async buffer.
