Use the desktop library to save the state of Emacs from one session to another. Once you save the Emacs desktop--the buffers, their file names, major modes, buffer positions, and so on--then subsequent Emacs sessions reload the saved desktop.
You can save the desktop manually with the command M-x
desktop-save. You can also enable automatic saving of the desktop
when you exit Emacs, and automatic restoration of the last saved
desktop when Emacs starts: use the Customization buffer (see section Easy Customization Interface) to set desktop-save-mode to t for future
sessions, or add this line in your `~/.emacs' file:
(desktop-save-mode 1) |
If you turn on desktop-save-mode in your `~/.emacs',
then when Emacs starts, it looks for a saved desktop in the current
directory. Thus, you can have separate saved desktops in different
directories, and the starting directory determines which one Emacs
reloads. You can save the current desktop and reload one saved in
another directory by typing M-x desktop-change-dir. Typing
M-x desktop-revert reverts to the desktop previously reloaded.
Specify the option `--no-desktop' on the command line when you
don't want it to reload any saved desktop. This turns off
desktop-save-mode for the current session. Starting Emacs with
the `--no-init-file' option also disables desktop reloading,
since it bypasses the `.emacs' init file, where
desktop-save-mode is usually turned on.
By default, all the buffers in the desktop are restored at one go.
However, this may be slow if there are a lot of buffers in the
desktop. You can specify the maximum number of buffers to restore
immediately with the variable desktop-restore-eager; the
remaining buffers are restored "lazily," when Emacs is idle.
Type M-x desktop-clear to empty the Emacs desktop. This kills
all buffers except for internal ones, and clears the global variables
listed in desktop-globals-to-clear. If you want this to
preserve certain buffers, customize the variable
desktop-clear-preserve-buffers-regexp, whose value is a regular
expression matching the names of buffers not to kill.
If you want to save minibuffer history from one session to
another, use the savehist library.
