-----------------------

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?

Hi,

thanks for your comment.

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to use (with the very outdated default version that we have installed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.

Ping!

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

https://www.reddit.com/r/emacs/comments/44ojpk/interpreting_the_emacs_bug_list_what_was/

Are there any particular things blocking this patch from being 
applied?


Alexis.

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.

Just out of curiosity: is being compliant with the XDG Base Directory
Specification out-of-the-box (
https://standards.freedesktop.org/basedir-spec/basedir-spec-0.6.html)
currently viewed as a non-goal for Emacs?  (The emphasis being on
"out-of-the-box").

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.)
