I like it.

But shouldn't it create .emacs.d if it doesn't already exist?

I can think of several other packages which can benefit from 
this functionality (e.g. ido), so what about writing a function
which can make the decision on the fly --

and preferably move old files to .emacs.d.


Something like this [not tested]

(defcustom savehist-file 
           (expand-saved-state-file "history" "~/.emacs-history")
  "...")

(defun expand-saved-state-file (name &optional oldname)
  "Return expanded file-name NAME in directory ~/.emacs.d.
If OLDNAME exists, move that file into NAME, or delete OLDNAME if NAME
already exists."
  (let ((file (expand-file-name name "~/.emacs.d"))
	(oldfile (and oldname (expand-file-name oldname))))
    (if (and oldfile (file-exists-p oldfile))
	(if (file-exists-p file)
	    (delete-file oldfile)
	  (rename oldfile file)))
    file))

Re: Use .emacs.d in savehist.el

    But shouldn't it create .emacs.d if it doesn't already exist?

That would be a big general change in how Emacs stores its init files.
I don't want to go that far.

Ideally I was aiming to have both emacsen share their minibuffer

is OK, except you might want to use ~/.xemacs under XEmacs.  Something
like:

Yes, that's the only objection I could imagine myself.  I'm not sure what to
think of it.  OT1H it makes sense to try and share the history, but OTOH
there's a pretty clear risk that it won't work right.
To be on the safe side, I think it's best to keep them separate (and
I think the fact that XEmacs now uses ~/.emacs/init.el in preference to
~/.emacs indicates that the XEmacs maintainers have followed a similar
reasoning).  For the few users who actively use both Emacs and XEmacs and
who care about sharing their histories, I'd say: customize the savehist-file
variable.

Thanks, I wasn't quite sure which dir to use for XEmacs and I figured you'd
know better ;-)

It should work correctly -- the only thing that could not work are the
differences in coding systems.

Agreed.  That's exactly what the code I proposed does.

   Just for consistency sake, shouldn't it be `~/.emacs.d/.history', as
   we have ~/.emacs.d/.emacs ?

   I think `.emacs' is more likely to be most read by the user than the
   `history' file, so make this file hidden seems better, nop ?

I don't care about this kind of consistency.  The "." prefix doesn't make
much sense here: it's only useful to hide "administrative" files among other
non-adminitrative files.  E.g. in config files in ~ or for ~/.cvsignore.
If the user looks inside ~/.emacs.d he probably doesn't want to ignore the
emacs config file and the history file.  Otherwise, there won't be
anything left.  So if anything needs fixing it's the ~/.emacs.d/.emacs.

I agree with that reasoning.  It looks like the file name
~/.emacs.d/.emacs is a feature added since the last release.  So there
is no problem removing the dot, and it would be better to do it now,
so that we avoid an incompatible change between releases.

BTW, the name "~/.emacs.d/emacs" (with or without a dot) seems rather
weird, and gives me little clue what the file actualy is for.  Is it
an init file, like ~/.emacs?  If so, something like
"~/.emacs.d/init.el" would be a great deal more clear...

I've always wondered where the "~/.emacs.d" directory name comes from.

Wouldn't (convert-standard-filename "~/.emacs_savehist") be more

Though perhaps a standard function to do such name munging would be a
nice idea, e.g.:

  (user-customization-file-name BASE &optional DOTFILE)

if .emacs.d doesn't exist  =>  (concat "~/" (or DOTFILE (concat "." BASE)))
if .emacs.d does eixst     =>  (concat "~/.emacs.d/" BASE)

Then the savehist example would be (user-customization-file-name "savehist"),
and .emacs would be (user-customization-file-name "init.el" ".emacs")

I like this too, but functionality should be:

If DOTFILE non-nil and ~/DOTFILE exists, use ~/DOTFILE, else [as above].

Otherwise, some old DOTFILE will suddenly "disappear" if the user later creates .emacs.d

Good point; this rule should apply to implicitly specified dotfile
name too of course.

Here's an implementation that seems to get the details right (it
probably ought to check that "~/.emacs.d" is actually a directory,
rather than seeing if merely exists or not):

(defvar user-customization-file-dir "~/.emacs.d")

(defun user-customization-file-name (base &optional dotfile)
  (unless dotfile
    (setq dotfile (concat "." base)))
  (setq dotfile (expand-file-name dotfile "~"))
  (if (or (file-exists-p dotfile)
	  (not (file-exists-p user-customization-file-dir)))
      dotfile
    (expand-file-name base user-customization-file-dir)))

The point is that are various simple rules and guidelines that apply
to _every_ customization file, if we allow them to go in either ~ or
in ~/.emacs.d, and it's silly to duplicate the code for each
customization file.

Centralizing the policy with a function also allows later changes or
enhancement to be done more easily and cleanly.

If you don't want to add it though, I will do it.

OK, now I see.

It may or may not make sense to use such a function for the init file
(though I agree that it's useful for elsewhere in Emacs.)  The
`command-line' has some strange magic going on in it: instead of
checking whether the file exists and is readable, it sets
`user-init-file' to t, and tries to load the filename
(`user-init-file-1'):

      ;; This tells `load' to store the file name found
      ;; into user-init-file.
      (setq user-init-file t)
      (load user-init-file-1 t t)

If the `load' function succeeds, it automagically binds
`user-init-file' to the loaded filename.  I don't know why this was
written this way, but maybe there is a reason?

Also, if you want to use this function for the init file, you would
have to account for the "_emacs" dotfile name used on MS-DOS and
MS-Windows.  In particular, MS-Windows uses "~/.emacs" by default, but
if that is not available it accepts "~/_emacs" as the dotfile.


Another note: it seems to me that most libraries that use ".emacs.d"
look for it in "~".  Would it make sense to extend the
`init-file-user' variable so that the directory goes into

      (concat "~" init-file-user "/.emacs.d")

instead?  Or should `init-file-user' continue to apply to init files
only?

The reason is to record the actual name found, whether it be .emacs or

We need the actual file name, not just something that we could
pass to `load' and load the same file.

That particular case does seem to needs special code.

You sure?  What is the intended usage of init-file-user anyway?

If normal libraries follow init-file-user, you could have a situation
where a user tries to write customization files into the home
directory of another user.  This doesn't make much sense, but I don't
understand when it makes sense to set init-file-user in the first
place.

If the customized values that Emacs read _came from_ another user's
init file, the only place to store them back is into that user's init
file.

Ordinarily you won't be able to write that file.  Instead you will get
a clear error message saying so.  That seems correct to me.

Meanwhile, in at least one case you WILL be able to write that file.
Namely, when you are root and you told Emacs to use your own personal
init file.  (In particular, this is what happens when you run emacs
under su.)

So we ought to make this work.

When you are root, creating a file or directory in another user's home
directory is problematic.  The file will be owned by root, and the
user won't be able to write to it.

I looked into the possibility of making Miles' "find customization
file" function do a chown and chgrp on the customization file, so that
this problem won't arise.  But Emacs doesn't have any built-in chown
or chgrp.  Dired can do it, but it's by calling an external program.

He can copy it, remove it, and then replace it, tho, so it's not nearly as
serious as it sounds.  Directories are more problematic.

I tend to think that people who use "emacs -u foo" as root just get what
they deserve.

In that case, maybe using root's own .emacs.d is actually the safer
thing to do, even if it is inconsistent with the meaning of "-u foo".

Here are two possibilities I can think of:

1. Let `init-file-user' apply to the init file only.  The init file
   has enough complications anyway that Miles' proposed function won't
   do the trick (apart from `init-file-user', there is the MS-DOS
   "_emacs" issue).  That function can be implemented so other
   libraries can use it, but it ignores init-file-user.

2. Go through the code in such a way that when init-file-user is
   non-nil, files are *read* from ~INIT_FILE_USER/.emacs.d, but
   *written* to the user's own home directory.  This can be made
   simpler by implementing Miles' function with an optional
   `read-only' argument, but we will still have to go through all the
   places that currently use .emacs.d to make sure they DTRT.

Personally, I like the first possibility because it's much
simpler... no one has actually complained about the interaction
between .emacs.d and init-file-user (at least until I brought it up
:-P), so I think it's not a big enough problem to justify a
far-reaching fix, especially close to release.

    In that case, maybe using root's own .emacs.d is actually the safer
    thing to do, even if it is inconsistent with the meaning of "-u foo".

I don't agree with Stefan.  I want this to work right,
which means, to edit the init file of the specified user,
or get an error if it can't write that file.

For what it's worth I agree with that, at least if it means not doing
anything special for root.  That towhich I'm opposed is code that
special-cases the situation where the user is root.

People who run Emas as root should get what they ask for (aka what they
deserve).  If they don't like it because it's "dangerous" they should simply
not do it.

    I tend to think that people who use "emacs -u foo" as root just get what
    they deserve.

If you su to root, Emacs automatically uses your own init file.

Re: Use .emacs.d in savehist.el

[Richard M. Stallman]

    When you are root, creating a file or directory in another user's home
    directory is problematic.  The file will be owned by root, and the
    user won't be able to write to it.

It sounds easy to fix.

      But Emacs doesn't have any built-in chown
    or chgrp.  Dired can do it, but it's by calling an external program.

I see no disgrace in using an external program.  Why worry about it?
(We could add a function to do it, if we want to.)

Hear hear!

So why not call it with a proper name like

   ~/.emacs.d/emacs.el or (IMO better) ~/.emacs.d/init.el

?

On a similar note, how about the shell init files .emacs_SHELLNAME?
Currently, they can go into ~/.emacs.d/ too.

I think it is a good change.  It increases consistency.
