Remote .emacs file

Remote .emacs file

[Leonid Grinberg]

Hello all,

I am a long-time Perl programmer, but unfortunately only know
Emacs-Lisp on a theoretical level. However, I do use Emacs a lot, and
have a relatively small, but still useful .emacs file. It has
configurations in it, without which I am starting to feel
uncomfortable. I use Emacs on many different machines (~5), and it
would be nice to have a standard .emacs file.

In Perl, I could easily put one on the web, and then have Perl
download it and use eval() to load the functions in it. However, I do
not know how to do this with Elisp.

Does anyone out there know (of a way to do it, or of another way)? I
would be very greatful if you told me! Thanks in advance!

I keep mine in a CVS repository (I keep all my config files in there) 
and symlink /path/to/cvs-repo/.emacs to ~/.emacs.

It has served me well for years now.

So these computers do not share the same home directory?  Bummer.

Try this in each machine's ~/.emacs file:

(load "/@server:/path/to/your-dot-emacs" nil nil t)

What I've done is to version control my home directory with CVS and
run a CVS server on my home cable modem machine.  One of the first
things I do on a new linux/unix machine, or cygwin installation, is to
check out my home directory and I'm up and running.

I even get version control of the files...:-)

(Note that even though the entire home directory has to be version
controlled, not all files in it has to be.  And they aren't in my
case.  I only actually version control all of the stuff that used to
take me the better part of a day to set up on a new machine)

I do a similar thing, but use unison which is a file synchroniser
rather than a version control. Works like a charm and has the
advantage over a remote .emacs that it works when the network is down!

Either I don't understand your problem or the answer is very easy.

Emacs reads the .emacs file from the user's home directory on loading.
Why not just get your perl script to download the file from whereever
and save it as ~/.emacs before starting emacs?

If emacs is already running and you want to load some file, M-x
load-file RET ~/.emacs RET is your solution.

This is assuming that your different computers are unix based.  I don't
know what you'd do on windows.

maybe this works for you: put the following lines in all your .emacs
files, and put the rest on a web server:

  (defun my-eval-url-callback ()
    (goto-char (point-min))
    (re-search-forward "^\r?$" nil 1)
    (delete-region (point-min) (point))
    (eval-buffer))

  (url-retrieve "http://example.org/emacs.el" 'my-eval-url-callback)

i tested this only superficially. i, too, use version control (darcs)
for my .emacs.
