How many times have you had to type in a long path in a shell to get to the directory you were just editing a file while inside emacs?
(require 'save-cwd)
(setq save-cwd-location "~/.emacs_cwd") ;; the default
(setq save-cwd-timer-period 5) ;; can be 1 and still be efficient, FYI
(save-cwd) ;; turns on the save-cwd minor mode
# cd `cat ~/.emacs_cwd`
or put it in an alias:
# cde() { cd `cat ~/.emacs_cwd` ; echo "changed to `cat ~/.emacs_cwd`" ; }
Will do funky things if invoked in two different emacs processes. (But why would you use two in the first place???)
M-x shell: Sure, you can do M-x shell and get a new shell there, but that's
simply inefficient when you have a bazillion shells, one per
directory.
emacsclient: Three is probably a way to pass a command to
emacsclient -e, but I didn't go that route. Would probably work
fine too though.
Bind to key: I'll eventually add (interactive) to the function to optionally "save now" rather than via a timer. But that would require moving the mouse back to emacs when you forget to run it before switching to a terminal window.
Leaving emacs in the first place.
