As each setting is variable one can store it in other variable or into
file, and get it back later.
(defun string-to-file-force (string file)
"Prints string into file, matters not if file exists. Returns FILE as file name."
(with-temp-file file
(insert string))
file)
(defun file-to-string (file)
"File to string function"
(with-temp-buffer
(insert-file-contents file)
(buffer-string)))
(defun data-to-file (data file)
"PRIN1 Emacs Lisp DATA to FILE"
(string-to-file-force (prin1-to-string data) file))
(defun data-from-file (file)
"Reads and returns Emacs Lisp data from FILE"
(car
(read-from-string
(file-to-string file))))
With those I am storing data into files and reading from files. It can
be just any complex Emacs Lisp data structure like hashes, it can be
lists, variables, just anything.
(setq my-hash (data-from-file "~/tmp/hash"))
(data-to-file mode-line-format "~/.emacs.d/modeline-saved.el")
saves `mode-line-format' into: "~/.emacs.d/modeline-saved.el" with
data looking like this:
("%e" mode-line-front-space mode-line-mule-info mode-line-client mode-line-modified mode-line-remote mode-line-frame-identification mode-line-buffer-identification " " mode-line-position (vc-mode vc-mode) " " mode-line-modes mode-line-misc-info mode-line-end-spaces)
and
(setq mode-line-format (data-from-file "~/.emacs.d/modeline-saved.el"))
loads the data from file back into `mode-line-format'
