one .emacs on multiple computers

one .emacs on multiple computers

Hi

I find I am running org mode from a Dropbox folder (and my org files) from
several machines - a couple of windows computers at home and one at work,
and several Macs. I have modified my .emacs file(s) ala Bernt Hansen's and
others modifications. However, all of the computers (of course) have
different paths to the latest version of the orgmode files in Dropbox
folder, and to my personal orgmode files, for example:

link to org-mode6.35i ->
"C:/Users/clsnyder/My Documents/My Dropbox/emacs_org/org-mode6.35i/lisp"
;;Windows machine 1
"C:/Users/cls/My Documents/My Dropbox/emacs_org/org-mode6.35i/lisp"
;;Windows machine 2
"/Users/clsnyder/Dropbox/emacs_org/org-mode6.35i/lisp"    ;;Mac machine 1

link to my todo file (for example) ->
"C:/Users/clsnyder/My Documents/My Dropbox/emacs_org/personal.org"
"C:/Users/cls/My Documents/My Dropbox/emacs_org/personal.org"
"/Users/clsnyder/Dropbox/emacs_org/personal.org"


Can I just do something like:

(defvar cls-org-file "C:/Users/clsnyder/My Documents/My Dropbox/emacs_org/")
;; WINDOWS VERSION
(defvar cls-org-file "/Users/clsnyder/Dropbox/emacs_org/") ;; IMAC VERSION

and then in each of the various .emacs files on each of the machines, just
do something like this throughout the file:

(add-to-list 'load-path "cls-org-file" + org-mode6.35i/lisp" )
(add-to-list 'load-path "cls-org-file" + personal.org" )

I don't know the correct syntax, but I would like to simply define the path
variable in each .emacs file, and then I could basically have use the same
.emacs file everywhere, with just a few different lines at the start to
differentiate the individual machine's path.

Thanks in advance.

Charles Snyder

Yes, that approach works.

Create a directory for your org-mode configuration in your dropbox
directory, say /path/to/dropbox/emacs-config/.

Put the contents of your .emacs in, say, emacs-config/init.el.

In the .emacs file on each machine, put:

(setq cls/config-dir "/absolute/path/to/dropbox/emacs-config/")
; note the trailing slash!
(load (concat cls/config-dir "init.el"))


In init.el, set the `custom-file' variable to make the emacs customize
interface store its data under the dropbox directory:

(setq custom-file (concat cls/config-dir "customize.el"))

Assuming your org-mode checkout is at emacs-config/org-mode6.35i, use
(add-to-list 'load-path (concat cls/config-dir "org-mode6.35i/lisp"))
(require 'org)
; other org-mode setup stuff

If you want to have some machine-specific configuration, there is no
need to use different files for different machines -- just check for the
hostname.

For example, I use org-mode on my laptop and my n900 smartphone, so my
startup files include:

  (setq jb/system
        (cond ((string-match "N900" system-name) 'n900)
              ((string-match "pythagoras" system-name) 'laptop)
              (t 'unknown)))

and later I can do:

(when (eq jb/system 'n900)
  (blink-cursor-mode 0))

to disable blink-cursor-mode on the n900 to save battery power.
(Emacs idle CPU usage with blink-cursor-mode: 1.5%. Without: 0% :) )


Because the path to your org files is rather long, you also might be
interested in this post, where Nathan Neff describes a way to easily
define shortcuts to jump to frequently used files/headings:

Many thanks from me too, Jan.  That's very helpful.

I also use git at work -- I have a central 'repo' on my work network share
and when using my laptop or desktop, I simply pull and push from/to the
central repo to keep everything in sync.

My structure is something like this:
~/org
~/org/aux
~/org/aux/emacs-config
~/org/aux/pics

Then on each of my computers I do 'ln -s ~/org/aux/emacs-config ~/.emacs'

When I make a change on either computer for some new option I want to use,
it's updated with the next pull from the other computer. I also used to keep
a ~/org/aux/elisp folder as well so that I could even sync my various
additional elisp files. I discontinued this only because my org.git repo
wasn't pulling/pushing since git doesn't like nested git repos. There is a
way to do this, but since I hardly change my elisp folder, I decided it
wasn't worth it.
