I just want emacs to load another file as the configuration file, and ignore the default file ("~/.emacs").
Note that I don't want to change the original "~/.emacs" file.
I've tried to change "$HOME" env variable, but it doesn't work.
(Platform is Linux.)
emacs --no-init-file --load=some-other-config.el
Or with short options:
emacs -q -l some-other-config.el
From the Emacs manual, section 48.4:
Emacs looks for your init file using the filenames ‘~/.emacs’, ‘~/.emacs.el’, or ‘~/.emacs.d/init.el’ you can choose to use any one of these three names […].
If you really want to use another file, you should consider patching Emacs and making a custom build. It looks like lisp/startup.el:1009 is a good place to start.
As far as I can see, the only option is to use -u to indicate another user's init file.
As @Benjamin quoted, there are three filenames you can choose. As normally, we choose ~/.emacs.d/init.el to be loaded. That's because, we can simply add more configuration files in this directory and add them all under version control(Git). Be sure ~/.emacs and ~/.emacs.el removed before u choose to use the ~/.emacs.d/init.el.
