running emacs in batch mode

running emacs in batch mode

[Helfer Thomas]

I want to use emacs to indent a lot of C++ files.
I tried to do this :

$ emacs --batch youpie.cxx -f mark-whole-buffer -f indent-region -f
save-buffer 

but didnot work. Can somebody tell me what I shall do ?

Thanks,

Helfer Thomas

I would rather use a script file:

emacs --batch -q -l script.el

with script.el containing whatever you want, in emacs lisp, something
like:

(dolist (file (file-expand-wildcards "/home/ht/src/*.cxx"))
  (find-file file)
  (mark-whole-buffer)
  (indent-region (point-min) (point-max))
  (save-buffer 0)
  (kill-buffer (current-buffer)))

Pour moi, la grande question n'a jamais été: «Qui suis-je? Où vais-je?» 
comme l'a formulé si adroitement notre ami Pascal, mais plutôt:

Use `C-h f' to see what arguments each function requires.

emacs --batch youpie.cxx --eval '(indent-region (point-min) 
(point-max))' --funcall save-buffer

Maybe you also want to try "emacs --script FILE"?
