bug#7747: Please put current file name in the prompt for rename-file

[Lennart Borgman]

The prompt for `rename-file' does not currently show the old file name
thought it is in the history for the prompt.

This is probably confusing for new users of the command. Wouldn't it
be better if the prompt should the current file name at init? (This
would be rather similar to what for example Windows Explorer does when
are renaming a file. And I guess this is common to must GUI:s.)

What old file name?  Which file is the "old file"?

What "current file"?

You can use `rename-file' from anywhere in Emacs.  Yes, if you use it from a
file buffer or from Dired then a reasonable default value is provided.  But
that's all it is: a default value.

We should treat this default value the same way we treat default values
generally (i.e., most default values).

I did not think of that, but I am sure you understood me.

Yes. And the only reasonable way to do that is to put them after the prompt.

Please try `M-x rename-file RET M-n'.

Yes, I know about that. What I mean is that this is very
counterintuitive for new users. They are used to have the name they
are renaming in the prompt (since that is what GUI software normally
do).

And I wonder whether the current behavior really helps old users most
of the time. I think most of the time I rename a file I just change
part of the file name.

Maybe he's lucky enough, but I must say I'm still lost.  Can someone
turn this into an actual bug-report, please?

Sorry, I should have been thinking of that you all use Emacs for
almost everything so this idea might be unfamiliar to you ;-)

It is just a simple but useful thing I want - too eat the cake and
have the cake. Though I was not aware of that first.

It is very useful that the current filename is in the prompt history
when renaming a file. However one more thing can be done now:

- Put the old file name in the prompt + made it selected (if visual
regions are on).

This is what at least the w32 GUI does. If you then want to overwrite
that filename you just start typing the new file name. If you want to
edit the file name instead you move the point first. This aborts the
selection and you can now edit as usual.

The advantage is more clarity and less key strokes.

This would work very well in Emacs too - at least when cua-mode is on.
(And in the case it is not on I think we should reconsider how
self-insert is handled.)


I realize now that this bug is quite a bit more general than for
rename-file. Sorry for that.

Yes, sorry for the confusion. This is what I meant.

I think this is a much better UI than the current implementation to
handle default values.

Clearly, that's the one you're used to from the rest of your w32 world.
Whether it's better or not also depends on whether you use and like
delete-selection-mode.
In any case, I don't think the default will change any time soon in this
respect, but I do hope that we will change the code so that end users
can choose between the two behaviors.

Yes, you have to like delete-selection-mode to use this. (But it also
makes it clear why delete-selection-mode is very useful.)

Agree. Fine.

This has nothing to do with w32!  I don't use w32, but still welcome these
changes because most of GUI improvements happen in web browsers nowadays,
and I think that some of them are quite good to adapt to Emacs.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Many prompts in Emacs have moved (or are moving) to the "don't use an
initial", but instead puts the thing into `M-n'.  There are advantages
and disadvantages to this (the main advantage is that you can just start
typing without saying `C-a C-k' first if you don't want the default),
but it's a conscious design decision which won't be reverted, so I'm
closing this bug report.

Could someone identify for me one example of this change
which is not inside a large or complex package that is difficult to try out?
