M-: (setq custom-file "X")
M-x customize
do some editing
save (into X)
M-: (setq custom-file "Y")
get (from ?)
Question is "from X" or "from Y"?
Good point. I would think it should be Y.
Absolutely not. `(setq custom-file "Y")' means that you want Custom to
_write_ to Y. If you want Y to be read you have to load Y...
If you want Y to be your Custom file, write: (setq custom-file "Y")
(load custom-file) in your .emacs, as the docstring of `custom-file'
recommends.
The question was about "getting" values from a custom file without loading
that file. You are confirming, I guess, that there is no way to change
custom-file for purposes of get-but-do-not-load.
