I have this set in my init.el
(desktop-save-mode 1)
This works great, only I was wondering:
how can I change it to save the .emacs.desktop files into ~/.emacs.d instead of ~/
how can I stop it from asking me if I want to save (only occurs the first time I close emacs after a reboot, from then on it assumes yes, which is what I always want to happen)
I use the following, which works for me:
;; Automatically save and restore sessions
(setq desktop-dirname "~/.emacs.d/desktop/"
desktop-base-file-name "emacs.desktop"
desktop-base-lock-name "lock"
desktop-path (list desktop-dirname)
desktop-save t
desktop-files-not-to-save "^$" ;reload tramp paths
desktop-load-locked-desktop nil
desktop-auto-save-timeout 30)
(desktop-save-mode 1)
Well, I actually set (desktop-save-mode 0) and then use M-x my-desktop to kick things off:
(defun my-desktop ()
"Load the desktop and enable autosaving"
(interactive)
(let ((desktop-load-locked-desktop "ask"))
(desktop-read)
(desktop-save-mode 1)))
But that's because my session is frequently in excess of 100 files, mostly via tramp, and so I prefer to make loading it a manual task, and not clobber the desktop file otherwise :)
I recommend checking out the Emacs Wiki: http://www.emacswiki.org/emacs/DeskTop
There are some useful enhancements to the default functionality. In particular, I recommend adding some method of auto-saving your desktop mid-session, as it's really annoying if your system crashes when Emacs has been running for several days, and your desktop hasn't been saved in the interim.
Since Emacs 24.4 the desktop file is auto-saved periodically by default. See the desktop-auto-save-timeout variable (which I've also added to the block above). Thanks to GDP2 and Dexter Morgan for their comments on this.

Customize desktop-dirname variable.

Customize desktop-save variable.
Wanted to share how my sessions are organized.
Requirements:
Solution:
Install package(plugin) workgroups2 -> https://github.com/pashinin/workgroups2
Add following lisp code to your ~/.emacs.d/init.el or ~/.emacs:
->
(setq server-socket-dir "~/.emacs-local/server")
(defun nk-server-start (custom-server)
; (nk-server-start "abe")
(setq server-name custom-server)
(server-start) ; run emacs server
(setq wg-session-file (concat "~/.emacs-local/sessions/" custom-server))
; (setq wg-session-file "~/.emacs-local/sessions/foo")
(workgroups-mode 1)
(wg-switch-to-workgroup custom-server)
)
; Run file in specific server (foo)
; emacsclient -n callback.sh -s ~/.emacs-local/server/foo
; Show server name in title bar
(setq frame-title-format '("" "%b @ " server-name))
; https://www.emacswiki.org/emacs/FrameTitle
; ;; What to do on Emacs exit / workgroups-mode exit?
(setq wg-emacs-exit-save-behavior 'save) ; Options: 'save 'ask nil
(setq wg-workgroups-mode-exit-save-behavior 'save) ; Options: 'save 'ask nil
Function nk-server-start is called when emacs is started.
It has one argument - sesssion name.
We can start emacs-session foo by running following command from terminal:
setsid emacs --eval '(nk-server-start "foo")' &
If we want to open file in session foo from terminal we need to run:
setsid emacsclient -n -s ~/.emacs-local/server/foo file.txt >> /dev/null &
When we close session, all buffers,settings, etc. are saved in file ~/.emacs-local/sessions/foo
When we run command setsid emacs --eval '(nk-server-start "foo")' & next time, all buffers will be restored
Because commands are large and I am lazy :) I made some scripts and added them to my $PATH in order to ease this:
em_start_foo.sh - Run session, used only once to start session
#!/bin/bash
setsid emacs --eval '(nk-server-start "foo")' &
em_foo.sh - Add files to session
#!/bin/bash
setsid emacsclient -n -s ~/.emacs-local/server/foo "$@" >> /dev/null &
Now we just run from terminal:
$ em_start_foo.sh # start foo session
$ em_foo.sh file_1.txt # open file_1.txt in foo session
$ em_foo.sh file_2.txt file_3.txt # open file_2.txt and file_3.txt in foo session
Multiple sessions can be run in parallel of course.
Let's say we created also scripts em_start_foo_2.sh, em_start_foo_2.sh, em_start_foo_3.sh, em_start_foo_3.sh (somewhere in $PATH of course)
Then we can do something like this:
$ em_start_foo.sh # start foo session
$ em_start_foo_2.sh # start foo_2 session in separate emacs
$ em_foo.sh file_1.txt # open file_1.txt in foo session
$ em_foo_2.sh a.txt b.txt # open a.txt and b.txt in foo_2 session
$ em_start_foo_3.sh # start foo_3 session
$ em_foo_3.sh tmp.txt # open tmp.txt in foo_3 session
##### Close emacs foo_2 from gui - session is automatically saved ###
$ em_start_foo_2.sh # start foo_2 session with all buffers restored
Package workgroups2 is really great!
My emacs init file with session options is available at: https://github.com/nexayq/dot_files/blob/master/emacs/dot_emacs_d/init.el
