;; Many editors (e.g. Vim) have the feature of saving minibuffer
|
|
|
|
|
;; history to an external file after exit. This package provides the
|
2005-10-24 17:21:30 +00:00
|
|
|
|
;; same feature in Emacs. When set up, it saves recorded minibuffer
|
|
|
|
|
;; histories to a file (`~/.emacs-history' by default). Additional
|
|
|
|
|
;; variables may be specified by customizing
|
|
|
|
|
;; `savehist-additional-variables'.

"Toggle saving of minibuffer history (Savehist mode).

|
With a prefix argument ARG, enable Savehist mode if ARG is

positive, and disable it otherwise. If called from Lisp, enable

the mode if ARG is omitted or nil.
