Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
[Message part 1 (text/plain, inline)]
I wanted to combine a couple of modes for soft-wrapped text, so I wrote:
(defun soft-wrap-modes ()
(interactive)
"Turn on minor modes for soft wrap"
(if (called-interactively-p) (call-interactively
'adaptive-wrap-prefix-mode) (adaptive-wrap-prefix-mode))
(if (called-interactively-p) (call-interactively 'window-margin-mode)
(window-margin-mode)))
The idea is that soft-wrap-modes should toggle when used interactively,
just like the underlying mode commands. But this is not very nice. It could
be made a bit nicer using map, but is there no way to transparently pass
the interactivity of the current command down to the sub-commands? I
couldn't see a way to do this with the standard methods for testing whether
a command is called in interactive mode.

(I'm going through old bug reports that unfortunately have not received
any responses yet.)
I don't think there's any way to do what you want. (Somebody correct me
if I'm wrong.) And I don't really see how an interface that does this
would work, really. Something like
(with-everything-interactive-if-this-is-interactive
(adaptive-wrap-prefix-mode)
(window-margin-mode))
Well, in this case that would be a pretty trivial macro to write, but I
don't see this as being generally useful. So I'm closing this as a
"wontfix".

I think it would be more like
(funcall-preserving-interactiveness 'adaptive-wrap-prefix-mode)
(funcall-preserving-interactiveness 'window-margin-mode)
The main implementation of this would really be called-interactively-p,
when it examines the call stack.

That said, while I don't think it's impossible, I don't know if it's
really worth the trouble.
