find-file change between emacs 21 and emacs 22

find-file change between emacs 21 and emacs 22

[-- Attachment #1.1: Type: text/plain, Size: 667 bytes --]

In emacs 21 (what I'm use to), ^X-^F would put in the minibuffer the  
directory path with a final / on the end.  Simply hitting return  
would re-read the file.  If you wanted to read the directory, you  
would backspace and erase the / and then hit return.

In emacs 22, simply hitting return after the ^X-^F reads in the  
directory.  That confuses me a lot.  I'm simply not use to it.

Is it possible to revert it back to what emacs 21 did -- maybe a  
customized option or some variable I can set?

Thanks,

Most people wanted this change.  You seem to be the first one to want
the old and confusing behavior.  It is confusing because re-reading
the file is not something an Emacs user would normally want.  Can you
tell why you need that?

Not really, but the NEWS entry that describes the change shows a
work-around:

  ** C-x C-f RET, typing nothing in the minibuffer, is no longer a special case.

  Since the default input is the current directory, this has the effect
  of specifying the current directory.  Normally that means to visit the
  directory with Dired.

  You can get the old behavior by typing C-x C-f M-n RET, which fetches
  the actual file name into the minibuffer.

If I'm writing quick scaffolding code, I get my Makefile to compile  
and then execute the program and capture various things in different  
output files.  I want to reload the output files to look at them.   
Another example, (roughly the same situation) I'm mucking with my C++  
code and checking the assembly output trying to find things that the  
compiler optimizes better than other things.  Again, the output is to  
foo.s (the assembly language).  I need to reload the file after each  
test.

I did not find it confusing.  I thought it was really brilliant to  
give me two nice things with only one key stroke difference: reload  
the file or do the dired.  As it is now, I can only do one of those.   
(I haven't tried your suggestion yet.)

Oh! thats just as good!  I'll have to re-teach my fingers but that  
shouldn't be a problem.

I looked in the NEWS before my post and did not find the entry you  
mention.  (I was searching for find-file.) I'll look again.

Thanks for your help.

I use this instead:

(global-set-key "\C-cr" 'revert-buffer)

When I have to revert then I usually simply type any character (a),
emacs detects the file changed on the disk and offer me to revert it, I
press r and it's reverted. The only condition is that the file has to
be editable, but it usually is.

So it's simply: <any char>r
No modifier is needed.

Can it be simpler than that?

Wonderful!  I've been using emacs since '85 or so.  Never figured  
that one out.

My 2¢: C-x C-v RET

Sounds like you might wish to try turning auto-revert-mode on.

That entry indeed doesn't mention find-file.  I added that now.
Thanks.
