I have defined a buffer-local variable like this:
(defvar nngnorb-attachment-file-list nil)
(make-variable-buffer-local 'nngnorb-attachment-file-list)
I'm first setting a value for it in the buffer referred to by
nnir-tmp-buffer, then trying to copy that buffer-local value to a
different buffer. Here's what I'm seeing, which confuses me:
(with-current-buffer (get-buffer nnir-tmp-buffer)
nngnorb-attachment-file-list) --> proper, populated value
(buffer-local-value
nngnorb-attachment-file-list
(get-buffer nnir-tmp-buffer)) --> nil
I thought this was the whole point of buffer-local-value? Am I doing it
wrong?
On the other hand, using with-current-buffer is almost precisely the
same number of characters as buffer-local-value, so maybe there's no
point in insisting on the latter...
