I am currently using a machine that sometimes crashes and destroys my carefully built state in GNU emacs (all the files and buffer that I am editing). I then have to revisit all the files that I had been editing. This gets annoying if you are editing a large source tree. Is there an elisp function that could save the "state" of Emacs (say, a list of filename/buffer tuples) so that I can restore Emacs to its former state with just one function call when I restart it ? Thanks in advance. regards, Naim (naim@uswest.com)

What you definitely want to use is saveconf.el, but that is not much help against system crashes (your state information doesn't get written out). Your best hope is to use saveconf, exit emacs periodically, and restart it. Emacs is a marvelous program, and does many wonderful things, but it cannot protect you completely against a system crash. Maybe someone wants to add code to saveconf.el to periodically write out window state? -- steve baur@venice.SEDD.TRW.COM

Just use the command save-context. This command writes out a file which tells what files you were looking at, and what point in the files. The command recover-context will read in all the files and put point back where it was. I've occasionally found it useful to rename the saved info file as a way of documenting all the relevant files of some project I'm working on. This is useful for a large project, particularly reading someone else's code, when I might go back to working on that stuff after doing other things for a few months. Duke

As someone recently posted, you needn't exit, just "M-x save-context". > [...] Maybe someone wants to add code to saveconf.el to periodically > write out window state? No need. Get a copy of my timer package, which consists of: timer.el: a library of Lisp functions that implement and support general purpose interval timers for GNU Emacs; timer.c : a small C program that accesses the system clock. It's probably in the OSU archives and I can send it directly to those without access. With the timer package installed you can say (start-timer "context-auto-save" 'save-context 300 300) in your .emacs file to cause window contexts to be saved every five minutes. Put: (setq save-buffer-context t) in your .emacs also if you want the contexts of all buffers saved, otherwise you will just get only those buffers that have a window.

It would be nice if emacs could call save-context after auto-saving. Maybe a next version can have a hook for this. -- Piet* van Oostrum, Dept of Computer Science, Utrecht University, Padualaan 14, P.O. Box 80.089, 3508 TB Utrecht, The Netherlands.

A hook into the auto-save code would be a good thing, indeed. crypt.el could use such a hook to insure that crypted, compressed, etc. files are auto-saved using their proper encodings.
