What do you mean by "without any user interface"? Which parts of
Emacs would you like to lose?
The editing part. I would like to be able to do emacs -Q --batch --eval,
but I have no need for typing stuff into buffers in this use case.
(I guess the --eval argument will do some editing, because otherwise
all you'd be able doing is numerical calculations, and that will make
Emacs pretty much useless.)
No, there's no such option, if I understand you correctly. Emacs
cannot work without at least one buffer and one window, even in batch
mode (though it never displays that window under -batch).
