Documentation

Non-nil if Savehist mode is enabled.

See the savehist-mode(var)/savehist-mode(fun) command for a description of this minor mode. Setting this variable directly does not take effect; either customize it (see the info node (emacs)Easy Customization) or call the function savehist-mode(var)/savehist-mode(fun).

Probably introduced at or before Emacs version 22.1.

(define-minor-mode savehist-mode
  "Toggle saving of minibuffer history (Savehist mode).

When Savehist mode is enabled, minibuffer history is saved
to `savehist-file' periodically and when exiting Emacs.  When
Savehist mode is enabled for the first time in an Emacs session,
it loads the previous minibuffer histories from `savehist-file'.
The variable `savehist-autosave-interval' controls the
periodicity of saving minibuffer histories.

If `savehist-save-minibuffer-history' is non-nil (the default),
all recorded minibuffer histories will be saved.  You can arrange
for additional history variables to be saved and restored by
customizing `savehist-additional-variables', which by default is
an empty list.  For example, to save the history of commands
invoked via \\[execute-extended-command], add `command-history' to the list in
`savehist-additional-variables'.

Alternatively, you could customize `savehist-save-minibuffer-history'
to nil, and add to `savehist-additional-variables' only those
history variables you want to save.

To ignore some history variables, add their symbols to the list
in `savehist-ignored-variables'.

This mode should normally be turned on from your Emacs init file.
Calling it at any other time replaces your current minibuffer
histories, which is probably undesirable."
