loading specific .emacs file on command line?

loading specific .emacs file on command line?

[john doe]

Hopefully, someone can answer a couple of questions I
have--thanks in advance for anyone who responds.

Looking at the emacs man page I see there is a line
switch that allows you to use someone elses dotfile
when loading emacs:

emacs -u jdoe

Is there a line switch to load a specific .emacs
file... if you have more than one for the same user?
My problem is I have large sections of my .emacs file
that I want to use sometimes and not other times. Can
I have large sections of the .emacs file load only for
some files and not others?

Thanks.

You could do something like this: say you want to be able to run
emase with a --foo switch, and you want certain things to happen
only when --foo is given on the command line. Something like this
in your .emacs file would do:

(when (member "--foo" command-line-args)
  ;; do
  ;; stuff
  ;; here
  (setq command-line-args (delete "--foo") command-line-args))

You could break your .emacs file into multiple *.el files, byte-compile them
if you want, and either load them from your .emacs file:

(if foo
   (load-file "~/foo"))
(if bar
   (load-file "~/bar"))

or load them explicitly on the command line:

emacs
emacs -l ~/foo
emacs -l ~/bar
emacs -l ~/foo -l ~/bar

Or for another approach - having broken up the emacs file I use the
name parameter on the command line and use the following defun

(defun rajm-get-emacs-class ()
  (let ((emacs-class
	 (cdr (assoc 'name initial-frame-alist))))
    (cond
     ((not emacs-class) 'full-class)
     ((string-equal "VM" emacs-class) 'vm-class)
     ((string-equal "rajm" emacs-class) 'full-class)
     ((string-equal "Root" emacs-class) 'root-class)
     ((string-equal "Gnus" emacs-class) 'fs-agent-class)
     ((string-equal "default" emacs-class) 'nil)
     (t 'remote-class))))
(defvar rajm-emacs-class (rajm-get-emacs-class))

And then load files in .emacs based upon rajm-emacs-class

Cool.  I use the -name vm option to differentiate an instance of
Emacs running VM from my normal editing session, via .Xdefaults:

Emacs*cursorColor:      blue
Emacs*pointerColor:     blue
vm*cursorColor: red
vm*pointerColor:        red
