Hi:

I just found that ffap-other-window ignores when ffap-require-prefix is
non-nil.

Looking at the code it seems to be that find-file-at-point has:

(and (called-interactively-p 'interactive)
     (if ffap-require-prefix (not current-prefix-arg)
	 current-prefix-arg))

but ffap-other-window calls find-file-at-point no interactively. Same
for ffap-other-frame, ffap-other-tab and so on...

I am not sure if the (called-interactively-p 'interactive) test is
actually needed in the first place, but I could be wrong. Is this
intended?

Best,
Ergus

What would be the point of supporting ffap-require-prefix when you
call ffap-other-window?  That variable controls whether to invoke
ffap-file-finder, which is not suitable for -other-window commands, I
think?  That is why, AFAIU, when not called interactively,
find-file-at-point doesn't call ffap-file-finder at all, and therefore
there's no point in heeding ffap-require-prefix.  Right?

Hi Eli:

Yes, that's what I expect, but it is actually offering the completion when using the other-window alternative.


Just:

emacs -Q
M-x ffap-bindings
M-: (setq ffap-require-prefix t)
Write /somedir

C-x C-f  (you see: ~/)

But 

C-x 4 f (you see /somedir)

This seems to be related with the ffap-prompter called before the switch then?

Best,

Yes, I think so.

Hi Eli:

So, what do you think? The fix may be to put the ffap-require-prefix
condition in ffap-read-file-or-url directly or in ffap-prompter??

BTW:

Looking at the ffap code I think some minor update/cleanup will be
beneficial any-way.

Nothing very drastic, for example, isn't more consistent to make
ffap-bindings a minor mode to allow load and unload? Or use the
"interactive" in find-file-at-point to simplify the initial conditions
there and remove the optional? Or update the global-set-key to use the
new keymap-set thing? Or add autoload decorators to the interactive
functions?

WDYT?

I don't understand what you want to achieve by that, so please
elaborate.  ffap-file-finder's default value is a command that doesn't
display the file in another window, so how will ffap-require-prefix
help here?

It's hard to say without seeing the code you have in mind.  Please
post a patch, and let's take it from there.

 From the example above I expect that after:

(setq ffap-require-prefix t)
C-x 4 f

You see ~/ instead of /somedir. Like when we do C-x C-f.

As I said before, ffap-prompter is causing this because it is called
before switching window.

So ffap-file-finder is actually called at point before going to another
window. And it does not have any ffap-require-prefix condition. My
question is actually that.

We need to put the ffap-require-prefix condition somewhere in
ffap-read-file-or-url or ffap-prompter. Because this problem happens
with the other-frame and other-tab variants as well.

That's not what ffap-require-prefix does:

  (defcustom ffap-require-prefix nil
    "If set, reverses the prefix argument to `find-file-at-point'.
  This is nil so neophytes notice ffap.  Experts may prefer to disable
  ffap most of the time."

So what we need is fix how the prompt is calculated, not what is the
meaning of the prefix arg.

Once again, calling ffap-file-finder in this case is WRONG!  We need a
function that visits the file in another window, and ffap-file-finder
doesn't.

IOW, you are talking about a very different change to
ffap-other-window.

I think we need to rewrite the interactive spec of those to do what
you want.  ffap-require-prefix is not related to this at all.
