Starting Emacs with different init file

Starting Emacs with different init file

[Joachim Nilsson]

Hello Emacs lovers!


I want to use different .emacs init files for different projects. This 
mostly because my lisp-fu is weak. The various startup-options I found 
does not seem to support:

--init-file=~/Projects/.emacs
--init-file=~/Work/Project/Customer1/.emacs
--init-file=~/Work/Project/Customer2/.emacs
--init-file=~/Work/Project/Customer3/.emacs

etc.

Is it planned *not* to support this scheme or is it merely an obvious 
oversight? I'm aware that this is probably easily fixed with some elisp 
magic, but I think more people than I could use it.


Regards
  /Joachim

don't know if that helps, but I created (on a Linux machine) an extra
user especialy for that purpose and call emacs like

emacs -u other_user

You could leave an empty .emacs file on your main file, and then M-x
load-file RET filename to load the .emacs file from the directory, but
that would probably be more trouble then it's worth.

I wonder if you did something like:

(load-file "./.emacs")

in your .emacs, would that work?

Yep.

That did the trick!

Now, if only I knew how to traverse up the dir tree from where I start
emacs and let it take the first init file one it finds until it reaches
$HOME/.emacs-default. Like this:

~/Work/Projects/Customer_One/Product_Series1/SW/src/
~/Work/Projects/Customer_One/Product_Series1/SW/
~/Work/Projects/Customer_One/Product_Series1/
~/Work/Projects/Customer_One/.emacs

or

~/Work/Projects/Customer_Two/Productum/HW/vhdl/
~/Work/Projects/Customer_Two/Productum/HW/
~/Work/Projects/Customer_Two/Productum/
~/Work/Projects/Customer_Two/
~/Work/Projects/
~/Work/
~/.emacs-default

Looks like a recursive problem to me, and maybe even something I can put 
together myself even.


Thanks!

It's already been done for you!

What is it about the different projects/jobs that requires totally
different init files? I suspect there is a much better solution, but
without knowing what it is you need different for the various
projects, its impossible to make any suggestion.

        emacs -l ~/Projects/.emacs

This will load both ~/.emacs and ~/Projects/.emacs.
If you only want the latter, then use:

        emacs -q -l ~/Projects/.emacs

But maybe improving your lisp-fu is the way of wisdom,
