Hi all, 

I running emacs 21.4.1. I'm trying to do some fancy ediff stuff. 

Actually not terribly fancy, I just want to invoke it from the command line with parmeters similar to "diff", specifically using the -L option to give more descriptive names to the buffers. Currently I can ediff two files by doing the following... 

emacs --eval='(progn (setq ediff-diff-options "-wbB") (ediff-files "file1" "file2"))' 

Maybe there's an easier/better way? 

ANYWAY, 

The path I'm currently on requires me to hook into the "ediff-startup-hooks" with the following code in my .emacs file... 

(require 'ediff) 

;; Get rid of the annoying little (separate) ediff window and 
;; turn it into a 3rd pane in the main emacs window. 
(setq ediff-window-setup-function 'ediff-setup-windows-plain) 

;; Put files side-by-side 
;(setq ediff-split-window-function 'split-window-horizontally) 

(defun my-ediff-startup-hooks () 
    (set-buffer ediff-buffer-A) 
    (rename-buffer "bobA") 
    (set-buffer ediff-buffer-B) 
    (rename-buffer "bobB") 
) 

(add-hook 'ediff-startup-hooks 'my-ediff-startup-hooks) 

OK, so this is just baby-step code because clearly "bobA" and "bobB" are not useful, but I can't even get THIS to work! I even tried inserting a line I knew would fail in the defined function (something like (undefined_bob_qwerty)) and I never got a complaint when I fired up a new instance of ediff. 

(but I know it was picking up my changes to .emacs because if I made a syntax error then it would warn me about that.) 

What am I doing wrong? 

Thanks,
