-----------------------
I'd like a switch for the emacs command line, something like
--user-emacs-directory, that sets the user emacs directory on startup,
rather than hardcodes ~/.emacs.d/. So, for example:
emacs --user-emacs-directory ~/mine.d/
Will look for the emacs init.el in ~/mine.d/init.el.

[-- Attachment #1.1: Type: text/plain, Size: 978 bytes --]
Hello,
attached is a patch which tries to implement the desired feature. It should
apply cleanly atop master (b91eafe31a524b391d5cec079cf8f36c2f9d5f30)
With this patch, emacs accepts a new command line argument:
--user-emacs-directory=DIR
which has two effects:
1. it sets the `user-emacs-directory' variable to DIR (instead of the
default "~/.emacs.d")
2. it looks for the init file in DIR/init.el (and only there: ~/.emacs & co
are bypassed)
This doesn't impact anything else in emacs' startup sequence.
Implementationwise, I'm not very proud of having to define a new global
variable, but I fail to see how to do otherwise, except maybe wrapping the
whole `command-line' function in a let form to use a local binding.
Please do not hesitate to criticize or ask me for any modification which
would be desirable. This is the first patch I propose to emacs; I don't
expect to have it right on the first try.
Thanks in advance,
François

I'm not saying it's the right solution, but you could use an environment
variable (eg EMACS_USER_DIRECTORY) rather than a command-line switch to
control this. This would be consistent with eg EMACSDATA, and also I
think with how other applications normally let you control where they
look for their init files (?). But on the other hand, environment
variables can be easier to overlook than explicit flags eg when
debugging.
On the other other hand, the OP could just do
ln -s mine.d .emacs.d
so I'm not sure what the point of this feature would be, unless eg you
frequently want to swap between different .emacs.d's?

Yes, you're right, this is a very good idea. I'll develop a new patch
for this as soon as I can.

I'm not sure about the OP's use case, but I can tell about mine: at
work, I try to maintain a sensible set of init files for my co-workers
to use (with the very outdated default version that we have installed
by default on our systems: 23.2). On the other hand, on my machine, I
maintain a locally-installed Emacs version that is more up-to-date. In
order to maintain both sets of init files, I need to be able to run
both versions of Emacs at the same time, which prevents me from
symlinking ~/.emacs.d/
There are reddit and stackexchange questions hinting at the same kind of use:
http://www.reddit.com/r/emacs/comments/2y1b3a/how_can_i_easily_keep_different_emacsd_folders/
http://emacs.stackexchange.com/q/4253/221
Since these questions concern a broader audience, do you think that we
should add emacs-devel to this discussion?
Thanks,
François

Attached is a new patch implementing this idea. The differences with
respect to the first version are:
1- `user-emacs-directory' is read in the `EMACS_USER_DIRECTORY'
environment variable instead of from the command-line;
2- a few custom variables are declared in
`custom-delayed-init-variables' in order to account for the new value
of `user-emacs-directory'.
Once again, please don't hesitate to comment.

after the lack of reaction to my last email, I would like to have one
more chance of getting emacs-devel's feedback on this issue (namely:
being able to tell Emacs where to find its init file).
Is nobody interested in this feature? Or is the proposed patch not adequate?
In the former case, please just say so, so that we can maybe mark the
bug as "wontfix" and let it be clear. In the latter case, I'm still
welcoming any comment on the proposed solution. And of course I'm

I'm interested in this feature, I just didn't have time to test it yet.
I'll try to look at it soon.

OK, I've tested it and it works great. I vote for merging this if
someone is counting.
Just one question: why is `getenv' called twice?

Thanks for testing

with the currently implemented logic, the environment variable has two
different impacts: (1) it sets the `user-emacs-directory' variable,
and (2) it changes the logic used to determine the init file. There is
currently no `let' form encompassing the whole `command-line'
function, so I had to either
1- add one (which might be the most correct implementation, but
generates a very large patch for mostly unchanged lines)
2- define a global variable (which seems unnecessary), or
3- call `getenv' multiple times.
I chose the latter, but am perfectly open to rewriting the
implementation if you feel it would be better.

That's the better option.
You can ask diff to ignore whitespace changes, which keeps the patch readable.

Here is a new version introducing a `let' form spanning everything
needed. There is no need for two calls to `getenv' anymore.
I've attached the patch in two versions: with and without whitespace
changes (git diff -b), to make it easier to review.
Thanks,
François

Ping!
Someone on reddit recently enquired about the status of this
issue:

Are there any particular things blocking this patch from being

Frankly, I don't think there are important enough use cases behind
this request to add yet another option that allows to change a
well-established constant. But that's me. (Didn't see any
enthusiastic reactions from others, either. Not sure what that
means.)

I think it might make sense... it might make some debugging and testing
cases easier, for instance.

You mean, the need to temporarily point HOME to some other place? Is
that really so problematic as to require yet another knob in Emacs?

Yeah, that's true. HOME is easy to switch around, so it doesn't make
much sense to offer this extra knob.

As an Emacs user I would like to kindly request you to reconsider this bug.
I think that the added complexity (look at the patch size, and even that is more
comments than code) is more than justified by the convenience it adds. Yes, there are
some workarounds which are either cumbersome (like fiddling with symlinks) or break
things (like adjusting $HOME). Using straightforward approach is better because it's
100% backward-compatible, easy to use and aligns well with user expectations (many
other programs allow you to override default config location with environment variable).
best regards,
Max.

The "complexity" mentioned in the discussion of this bug did not
allude to the size or complexity of the patch, it alluded to the
complexity this would add to Emacs and its development/maintenance:
where previously user-emacs-directory and the directory pointed to by
HOME in the environment were one and the same, now they will not be.
I think if we want to revisit this issue, we should come up with the
use cases where this feature would be useful, and see if they are
important enough to justify the price. AFAIR, no use cases were
provided with the original request.
Thanks.

See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=583 - some skepticism
More recent effort:
https://lists.gnu.org/archive/html/emacs-devel/2016-09/msg00167.html -
seems to have stalled.

I don't think there's any decision about that, either way.

I think the case for adding this feature has been very well made in
https://debbugs.gnu.org/15539#66
and others, and personally I think it seems worth adding.
See also https://debbugs.gnu.org/25163, esp #47 and #50.
(I'd also like to see support for an XDG-style layout as an option (the
default is another matter), compared to which this is very small beer.)

Glenn Morris mentioned Bug#15539's user-emacs-directory issue here:
https://bugs.gnu.org/583#68
... so this email is giving you a heads-up that I recently installed a patch
into GNU Emacs master that should allow something approximating Bug#15539's
requested behavior. For example, one can run Emacs like this:
XDG_CONFIG_HOME=/home/rms/.config emacs
to employ user rms's Emacs configuration, instead of your configuration.
The patch I installed did not do anything special to fix bug#15539, as the new
Emacs behavior is a natural fallout of supporting the XDG spec's requirements
for XDG_CONFIG_HOME.
This all assumes people are using the XDG-conforming locations for config files,
which I hope is good enough since older Emacs obviously wasn't meeting the
Bug#15539 need anyway.

This is an improvement, but it is not a proper solution to #15539, for
some of the same reasons that "just change HOME" wasn't. XDG_CONFIG_HOME
is not an Emacs-specific variable, so changing it will impact other
things that may be called from within Emacs.

True, but it should suffice for many use cases mentioned in Bug#15539. Of the
cases mentioned here:
https://bugs.gnu.org/15539#66
XDG_HOME should suffice for most of issues mentioned. Not all: for example,
overriding XDG_CONFIG_HOME overrides Gtk configuration, font configuration, and
other settings covered by the XDG convention, whereas one might want to override
just ~/.config/emacs. But it strikes me that this is often just as much of a
feature as a drawback, since Gtk etc. configurations influence Emacs so much
that they really ought to be saved/restored when one is thinking of
saving/restoring Emacs settings.
One might have a situation where one wants to vary (or save) files traditionally
kept in ~/.emacs.d/, and no other files. But it's also quite plausible that one
will want some of those files and not others, just as one might want
~/.config/emacs and ~/.config/fontconfig but not ~/.config/gtk-3.0. And it's
unlikely that a single option will have all the fine-grained control that one
would need for all these situations. Instead, it's probably better just to
suggest to people that they set up $HOME (or perhaps $XDG_CONFIG_HOME) to point
to a directory full of configurations that are just they way they like it.

As the OP approximately six years ago, I neglected to add the "use-case"
I wanted --user-emacs-directory for, namely to experiment with
~/.emacs.d/init.el including installing new packages via elpa. I still
think there's a need, especially as the number of useful packages have
grown and they can interact. I currently use the "symlink" approach when
I want to start adding new packages and configurations. It's useful to
return to a "known good state" if my init.el hacking careens off the
tracks. Since there was already a _variable_ user-emacs-directory, I
thought I was just asking to set it early at the command line. It seemed
to be analogous to --load for an emacs file or --user for another user's
init file. I didn't realize it had a "read-only" flavor.
Yes, this switch adds another knob, but I happen to think its a useful
knob and is consistent with --load and --user, both of which allow the
user to designate a different init file at the command line. Redefining
HOME at the command line and then "setting it back" inside init.el seems
convoluted. It could also potentially break site-start.el if some code
there relied on the right binding of HOME. Admittedly that's a
farfetched scenario, but not impossible either. Sure would be confusing
to debug if you didn't know what to look for. All the "do it yourself"
strategies (other than symlink) also force the user to deeply understand
the details of the init process, e.g. what switches to throw to override
various features. So if the criticism is "yet another knob" I would say
you are pushing people to construct homegrown solutions ... repeatedly.
The XDG patch will let emacs adhere to the XDG desktop conventions and
you can designate the user-emacs-directory implicitly as well, a
two-for-one special. Not every platform follows the XDG conventions, but
I personally mostly use linux, so I'm less concerned with those.

So I think the conclusion to this long thread was that we don't want to
add a specific switch for this, and instead people can say
"XDG_CONFIG_HOME=/whatever emacs" when they want to change these paths.
So I'm closing this bug report.
