Re: ediff-files from command line ?

[Who indeed?]

Bogdan,

Here is a shell script I use for ediff and emerge:

#!/bin/sh
SCRIPTNAME=`basename $0`
if [ $# -lt 2 ]
then
   echo "usage: $SCRIPTNAME FILE1 FILE2"
   exit 1
fi
#
if [ ! -f "$1" ]
then
   echo file $1 does not exist
   exit 1
fi
#
if [ ! -f "$2" ]
then
   echo file $2 does not exist
   exit 1
fi
if [ "$SCRIPTNAME" = "ediff" ]
then
    emacs --eval "(ediff-files \"$1\" \"$2\")"
elif [ "$SCRIPTNAME" = "emerge" ]
then
    emacs --eval "(mlw-emerge-files-command)" $1 $2
else
    echo Unknown script name: $SCRIPTNAME
    exit 1
fi
exit 0

Also, here is a relevant portion of my .emacs file:

(require 'emerge)
(defun mlw-emerge-files-command ()
  (let ((file-a (nth 0 command-line-args-left))
        (file-b (nth 1 command-line-args-left)))
    (setq command-line-args-left (nthcdr 2 command-line-args-left))
    (emerge-files-internal
     file-a file-b nil nil nil)))

I hope this helps.
