Subject: bug#7462: 24.0.50; prefix arg breaks `last-command' for `mouse-save-then-kill'
Date: Sun, 21 Nov 2010 12:28:09 -0800 [thread overview]
Message-ID: <83B82FC7FE604A9BAE6F07269980CC18@us.oracle.com> (raw)
emacs -Q
Add a call to `message' at the end of `universal-argument-other-key' and
another at the beginning of `mouse-save-then-kill'. Show the value of
`last-command' in these messages.
E.g.
(defun universal-argument-other-key (arg)
...
(restore-overriding-map)
(message "UAOK, last-command: %s" last-command)) ; @@@@@@
(defun mouse-save-then-kill (click)
"..."
(interactive "e")
(message "MSTK, last-command: %s" last-command) ; @@@@@@
...)
1. Click `mouse-1' somewhere.
2. Click `mouse-3' at another location in the same buffer.
3. C-u
4. Click `mouse-3' at the same location as #2.
IOW, you've just used `C-u' for the second mouse-3 click.
The messages you see are these:
MSTK, last-command: mouse-set-point
UAOK, last-command: mouse-save-then-kill
MSTK, last-command: universal-argument-other-key
The bug is that `last-command' is set to `universal-argument-other-key'.
`last-command' should still be `mouse-save-then-kill'.
This happens somewhere between the end of the call to
`universal-argument-other-key' and entrance to `mouse-save-then-kill'
(more precisely, before the `message' call in `mouse-save-then-kill',
which happens after `interactive').
`mouse-save-then-kill' tests whether the `last-command' was
`mouse-save-then-kill', and this test fails if `C-u' is used before the
second mouse-3 click.
