Here is how I do this on so called "Windows" OSes. Use at your own risk!
#!/usr/bin/env perl
# Time-stamp: <2003-08-22 13:57:12 Emilio C. Lopes>
use strict;
use warnings;
use Getopt::Long;
use File::Spec;
use vars qw( $emacs_client $ediff_fun $verbose $help $version );
$version="1.0";
{
GetOptions( 'verbose|v' => \$verbose
,'help|h' => \$help
) or usage(1);
usage(0) if ($help);
usage(1) if (@ARGV lt 2);
$emacs_client = 'gnudoit';
if (@ARGV == 2) {
$ediff_fun = 'ediff-files';
} elsif (@ARGV == 3) {
$ediff_fun = 'ediff-files3';
} else {
die "Error: Expecting two or three arguments.\n"
}
## Convert to absolute filenames; Translate backslashes to forward
## slashes; Quote the arguments.
map { $_= File::Spec->rel2abs( $_ ) ; tr /\\/\// ; $_ = "\\\"$_\\\""} @ARGV;
my $cmd="$emacs_client ($ediff_fun " . join (" ", @ARGV) . ") > " .
File::Spec->devnull();
print "$cmd\n" if ($verbose);
system "$cmd";
}
sub usage {
print <<"EOF";
Ediff version $version: Frontend to Emacs' ediff package.
Usage:
$0 file1 file2 [file3]
EOF
exit $_[0];
}
