M-x indent-region

M-x indent-region

[Sanford Selznick]

In emacs, 'M-x indent-region' is the best indent I've ever seen.

How can I trigger this action from the command-line and have emacs 
indent an individual file?

Thank you,
  Sanford

Maybe something like this.

emacs -batch --eval '(find-file "foo)' \
             --eval '(indent-region (point-min) (point-max))' 
             -f save-buffer -f save-buffers-kill-emacs

But I haven't tested it.

Whats wrong with just using GNU indent?  They should do the same
thing.

Well, for starters, it doesn't indent C++.  ;-)  Beyond that, it's more 
of a reformatter than a pure indenter, like emacs.  The emacs indent 
doesn't change the line number of any given token... all it does is 
change the indent of a given line.

I'm sure you can tell GNU indent to abstain from adding or removing
newlines.  But then, I haven't used it.

Then maybe you should try it and you'll know for sure.  ;-)

I got your previous suggestion is working.  Thank you!

Yeah.  Maybe it helps to set a really long max line length, and to
tell it to honor existing newlines.

But so far I've still only read the documentation, not tested it.
It's not important enough for me...

Obviously.  ;-)

Here's how the final version ended up...

emacs -batch -eval '(find-file "~/test")' -eval '(c-mode)' -eval 
'(indent-region (point-min) (point-max) nil)' -eval '(save-buffer)' 
-eval '(kill-buffer (current-buffer))'

Where '~/test' is the file that will be wrapped in place, keeping all 
tokens on the line they started on.  Note the '(c-mode)' in case the 
file doesn't end in a c-program extension.  And note the third argument 
on indent-region, which I'm not entirely sure is necessary or not.  But 
it's working fine.

Thanks again for your help.
