I assume you're alluding to its doc string:

| command-switch-alist's value is nil
|
| Documentation:
| Alist of command-line switches.
| Elements look like (SWITCH-STRING . HANDLER-FUNCTION).
| HANDLER-FUNCTION receives switch name as sole arg;
| remaining command-line args are in the variable `command-line-args-left'.
|
| Defined in `startup'.

I read that to mean whatever SWITCH-STRING you want to define, whether
"-foo", "--foo", or "---foo", etc. is what should be specified in
command-switch-alist.  It does say that HANDLER-FUNCTION receives the
switch name (vs. switch string), which could be interpreted to mean
"foo" in all those cases.  But a simple test proves otherwise, that
switch name means the same thing as switch string:

(defun foo-switch-handler (switch)
   (message "%s" switch))

(setq command-switch-alist
       (cons '("--foo" . foo-switch-handler) command-switch-alist))

The number of hyphens is irrelevant -- it can even be zero!  I just try
to follow the GNU convention that multicharacter (long) options should
be preceded by 2 hyphens.

Because I was looking for an easier implementation, and I think clarity
and readability are more important for ease of use.  If you want to
minimize typing at the command line, use a shell alias or function.

That doesn't look syntactically correct.

Since command line switches don't necessarily begin with a hyphen, you
might want to test each remaining arg like this:

	(and command-line-args-left
	     (not (string-match "\\`-" (car command-line-args-left)))
	     (not (assoc (car command-line-args-left) command-switch-alist)))

Very nice.  Here's another way, but it's not quite as nice since it also
pops up a *Buffer List* window:

emacs --eval '(setq pop-up-frames t)' FILE ... \
       --eval '(setq pop-up-frames nil)'

That works best with something like this:

(add-hook 'find-file-hooks
	  (lambda ()
	    (set-window-dedicated-p (selected-window) t))
(add-hook 'find-file-not-found-hooks
	  (lambda ()
	    (set-window-dedicated-p (selected-window) t)
	    nil)

I agree it is a lot easier to use command-switch-alist, especially when
I found that the original suggestion does not work in emacs 21.1 or
20.4.
However I have a question about your implementation since my reading of
the documentation on command-switch-alist indicates that the hyphen is
not included in the CAR of the alist.  I don't know how that plays with
double hyphen options.

If you are looking for easy, why would you want to type that big long
option before every file name?  Here is what I did to Oliver's function
to make it work with only one option that affects all the remaining file
names on the command line.

(setq
 command-switch-alist
 (append
  '(("fpf" . jcb-frame-per-file))))

 (defun jcb-frame-per-file (arg)
  "Open each file on the command line in a new frame.
This function is triggered by the '-fpf' command line option.
Each file on the command line that follows it is opened in its own
frame."
  (while (and command-line-args-left
             (not ((string-match "^--?" str)
                   (car command-line-args-left))))
    (find-file-other-frame
     (pop command-line-args-left) t)
    t))

>> Use as
>>
>> emacs --as-frames lirum.txt larum.txt
>

Invoke as:
 emacs first-file -fpf second-file ...

if the -fpf option is before the first file name then n+1 frames are
opened and *scratch* is in the first frame.

I have been watching this thread for several days and like others who
have responded I do not know of a command line option that will do what
you want.  Finally today it occurred to me that a function which I just
wrote (because I found doing multiple c-x 5 2's each time I started
emacs to be tedious) should be fairly simple to modify to do what you
describe.

The function that I wrote opens a number of frames based on the contents
of a list and positions the frames at specific locations on the screen.
It should not be difficult to adapt this function use a list of the
buffers associated with files that were opened with the command line as
the basis for the number of frames to create and to map the buffers in
list to the frames as they are opened.  Making it transparent would then
just be a matter of running the function from your .emacs file.  I do
not have the time right now to do those modifications but if you are
interested in doing it your self I will be glad to send the code to you.

Re: Open files in a new frames from command line

Michael,

Unfortunately you didn't specify what OS you are working on.
You basically need to start a server process from emacs, then
use a command line client that communicates with the server
to open files.  The process is slightly different dependent on
the OS you are using.

Unix/linux:
In emacs: M-x server-start
>From shell: emacsclient <file>
Don't recall if it works to specify mor than one <file> on the line, but
if not you can easily write a shell script to do this.

Win:
Download and install gnuserv
Check out: http://www.gnu.org/software/emacs/windows/faq3.html#assoc

Mac OS:
Also uses gnuserv mechanism...can't be sure, but I think it
came with the SDK.

Normally, people start Emacs once and then leave it running for the
whole session.  With that usage pattern, using C-x 5 f does not seem
to be so terrible.

How about:

   gnudoit -q (find-file-other-frame \"c:/temp/foo\")

Works for me under Win2k.  Replace filename with a shell variable and
you're done.

There is no such command line option, but you could make your own
command line option, if you put something like this (only slightly
tested) into your .emacs:

(defun my-is-option-p (str)
  "Return non-nil if STR is an command line option."
  (string-match "^--?"
		str))

(defun my-command-line-make-new-frames ()
  "Process open each files in a new frame.
This function is supposed to be an element of
`command-line-functions' (q.v.). Its functionality is triggered
if ARGI is \"--as-frames\" and opens each element in
COMMAND-LINE-ARGS-LEFT not starting with a slash as a file in a
separate frame."
  (when (string= argi "--as-frames")
    (unless (my-is-option-p (car command-line-args-left))
      (find-file (pop command-line-args-left)))
    (while (and command-line-args-left
		(not (my-is-option-p
		      (car command-line-args-left))))
      (find-file-other-frame
       (pop command-line-args-left))
      t)))

(push 'my-command-line-make-new-frames
      command-line-functions)


Use as 

emacs --as-frames lirum.txt larum.txt

It's a lot easier to use command-switch-alist:

(setq command-switch-alist
       (cons '("--other-frame" . find-file-other-frame-command-line-arg) ; -R
	    command-switch-alist))

(defun find-file-other-frame-command-line-arg (switch)
   "Visit next command line argument (after SWITCH) in a new frame."
   ;; (prog1 (car x) (setq x (cdr x))) == (pop x):
   (find-file-other-frame (prog1 (car command-line-args-left)
			   (setq command-line-args-left
				 (cdr command-line-args-left)))))

Open files in a new frames from command line

[Michael B. Schmidt]

Hello,

I need to open multiple files to work with them. I use the command: 
"emacs foo bar baz". This open the file foo,bar and baz each in a new 
Buffer. Is there away (command line option,script) to open the files in 
frames instead of new Buffers? (I know that I can open one of the files 
and then open each file with c-x 5 f but this is to much work :-)))

Thank you

Michael
