Save Emacs buffers when they lose focus
Emacs Lisp
Latest commit 701c98e Apr 26, 2016 @grammati grammati committed with Fix wrong-number-of-args when trigger function called with 0 args (#12)
This manifested in spacemacs when using, for example, `SPC w
l` (`evil-window-right`), because that calls `windmove-right` with no
arguments. This caused a wrong-number-of-arguments error because
`super-save-command-advice` required at least one argument.

super-save auto-saves your buffers, when certain events happen - e.g. you switch between buffers, an Emacs frame loses focus, etc. You can think of it as both something that augments and replaces the standard auto-save-mode.


Available on all major package.el community maintained repos - MELPA Stable and MELPA repos.

MELPA Stable is recommended as it has the latest stable version. MELPA has a development snapshot for users who don't mind breakage but don't want to run from a git checkout.

You can install super-save using the following command:

M-x package-install [RET] super-save [RET]

or if you'd rather keep it in your dotfiles:

(unless (package-installed-p 'super-save)
  (package-install 'super-save))

If the installation doesn't work try refreshing the package list:

M-x package-refresh-contents


Add the following to your Emacs config to enable super-save:

(super-save-mode +1)

If you want to enable the additional feature of auto-saving buffers when Emacs is idle, add the following as well:

(setq super-save-auto-save-when-idle t)

At this point you can probably switch off the built-in auto-save-mode (unless you really care about its backups):

(setq auto-save-default nil)
