[Message part 1 (text/plain, inline)]

Although I start my init.el by setting `user-emacs-directory' to something that suits me, emacs keeps on creating an unwanted "~/.emacs.d/". 

How to reproduce: 

Create an init file, say "~/.config/emacs/please-do-it.el": 
(setq user-emacs-directory "~/.cache/emacs/") 


;; (setq auto-save-list-file-prefix ;; I shall not have to do this 
;; (concat user-emacs-directory "saves")) 


Do the following in a shell session: 
$ cd 
$ rm -r .emacs.d # actually there was one 
$ ls .emacs.d 
ls: cannot access '.emacs.d': No such file or directory 
$ emacs -l ~/.config/emacs/please-do-it.el & 
$ ls -d .emacs.d 
.emacs.d 
$ ls .emacs.d 
$ 

There's nothing in .emacs.d, but the directory is there. It should not, as this is not my choice as an emacs user, and the only way I've got to state this is setting `user-emacs-directory' in my init file. 

Let's edit some file with emacs and wait about 2 minutes: 
$ ls .emacs.d 
auto-save-list 
$ 

In emacs, describe variable `user-emacs-directory': this is actually what I want, namely "~/.cache/emacs/". 
Quit emacs 

Is the auto-save guilty ? If I uncomment the part related to auto-save in please-to-it.el: 

$ rm -r .emacs.d 
$ emacs -l ~/.config/emacs/please-do-it.el & 
$ ls -d .emacs.d 
.emacs.d 
$ 

Edit some file and wait about 2 minutes; then: 
$ ls .emacs.d 
$ 

Nothing in .emacs.d. Let's see what I asked for auto-save: 

$ ls .cache/emacs 
saves14634-xanadu~ 
$ 

Alright... but it's not legitimate: as I've set `user-emacs-directory', I should not have to furthermore tell auto-save where to put its material. If I need to, this means I need to also for every possible package that uses user-emacs-directory. And emacs still trashes my home directory. 

I did not find bug reports on the subject, except for this one, which is precisely on topic:

Added (manually) to commit tagged emacs-26.1.92, in defcustom auto-save-list-file-prefix': 
:initialize 'custom-initialize-delay 

Done same tests with auto-save configuration commented out in "please-do-it.el". 
- The directory .emacs.d is created 
- It is populated with a directory auto-save-list-file-prefix 

Checked that emacs is actually the one I've just build: it is. 
Also checked that /usr/share/emacs/26.1.92/lisp/startup.el* are up to date: they are, though sibling .el are not affected except subdirs.el. 

Thus, no, it does not seem to work. 

Shall I try from another commit ?

Typo: you've certainly corrected by yourself, but it is actually auto-save-list that is created under .emacs.d, not auto-save-list-file-prefix

It's not a typo: auto-save-list-file-prefix is a defcustom from whose
value Emacs creates the name of the directory where it will save the
auto-save files.  The change was supposed to delay computing the value
of auto-save-list-file-prefix until after your init file is read, so
that it catches the new value of user-emacs-directory.

I mean: the directory that is created under ".emacs.d/' is not named " auto-save-list-file-prefix", but " auto-save-list"

Yes, auto-save-list-file-prefix is the variable whose value includes
the string "auto-save-list".  The problem is that the value of
auto-save-list-file-prefix is computed before user-emacs-directory is
updated by your init file.

Please try the following patch instead of the one I sent earlier:

This is expected, and cannot be helped, at least not easily, because
various variables are computed during the startup, when your init file
has not yet been processed.

But with the patch I sent the auto-save-history files should be in
your customized user-emacs-directory.  Did you check that?  If not,
please do.

I cannot look into this without seeing a minimal init.el file that
causes this.  In particular, I need to understand how come your
init.el file uses ~/.emacs.d when your user-emacs-directory is
different.

My latest patch should do that, please try it.

I don't think the solution proposed there would help in your case
because the value of user-emacs-directory is used to compute
auto-save-list-file-prefix before the command-line arguments are
processed.  IOW, by the time we look at the command-line arguments,
it's too late for auto-save-list-file-prefix: its value was already
computed using the default value of "~/.emacs.d".

Does this mean you are giving up on this issue, and don't want to
continue looking for its solution?

It turns out that patch was wrong and had bad consequences.  So it was
reverted.

I think the right solution for this kind of situation is to set
user-emacs-directory in the early-init file, instead of the normal
init file.

Personally I'd hope that we can get the XDG code sorted out so that we
could use the XDG_CONFIG_HOME environment variable for this sort of
thing.

In any case, perhaps it's worth documenting how to properly set
user-emacs-directory in the doc string.

Stefan Kangas

This is entirely my fault. My real init.el won't touch user-emacs-directory unless some environment variable is not set, which I removed during the test. Please accept my apologies. 

However, this does not affect the primary test "please-do-it.el".
