Version 0.6 of package Persist has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Persist describes itself as: ======================================== Persist Variables between Emacs Sessions ======================================== More at https://elpa.gnu.org/packages/persist.html ## Summary: This package provides variables which persist across sessions. The main entry point is `persist-defvar' which behaves like `defvar' but which persists the variables between session. Variables are automatically saved when Emacs exits. Other useful functions are `persist-save' which saves the variable immediately, `persist-load' which loads the saved value, `persist-reset' which resets to the default value. ## Recent NEWS: [Not available 🙁]
