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.
If instead of `M-: (setq custom-file "Y")' we set custom-file through
Custom, then the up to date Custom Info is _immediately_ in Y, without
having to save any further option. (Because saving `custom-file'
itself took care of things.)
So if somebody _really_ wants to change Custom file during an emacs
session (instead of from .emacs) the way to do it is through Custom.
Got it.
