super-save

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.

Installation

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-refresh-contents)
  (package-install 'super-save))

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

M-x package-refresh-contents

use-package

If you're into use-package you can use the following snippet:

(use-package super-save
  :ensure t
  :config
  (super-save-mode +1))

Emacs Prelude

super-save started its life as the extraction of a similar functionality I had originally developed for Emacs Prelude and the package is bundled with Prelude.

Usage

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)

Configuration

super-save will save files on command (e.g. switch-to-buffer) and hook triggers (e.g. focus-out-hook).

Both of those are configurable via super-save-triggers and super-save-hook-triggers. Here's a couple of examples:

;; add integration with ace-window
(add-to-list 'super-save-triggers 'ace-window)

;; save on find-file
(add-to-list 'super-save-hook-triggers 'find-file-hook)

You can turn off super-save for remote files like this:

(setq super-save-remote-files nil)

Sometimes you might want to exclude specific files from super-save. You can achieve this via super-save-exclude, for example:

(setq super-save-exclude '(".gpg"))

You can add predicate to super-save-predicates, this predicates must not take arguments and return nil, when current buffer shouldn't save. If predicate don't know needle of save file, then predicate must return t. Folowing example stop super-save, when current file in Markdown mode:

(add-to-list 'super-save-predicates (lambda ()
                                        (not (eq major-mode 'markdown-mode))))
