BTW, the line that was giving me trouble is
(kill-buffer (get-buffer “*Save Visited*”))

Anyway, it seems to be working as advertised; nice package.

I installed this and set it up, and then I got these dialog boxes asking me if I wanted to kill the “*Saved Visited*” buffer. It turned out that it was erroring when the directory ~/.emacs/persistent/ didn’t exist. You should make sure you can write to the file before you do (file-writable-p). You can try to create the directory with something like this:

(let ((dir (directory-file-name
(file-name-directory
(expand-file-name
(directory-file-name save-visited-files-location))))))
(if (not (file-exists-p dir))
(make-directory dir)))

No, I don’t know why directory-file-name should be there twice. I stole that from uniquify.el.

TheGZeus:Hmm, that’s odd…It’s been mostly working for me so far. I do sometimes have the replication problem, which is caused when you attempt to C-g out of a save-visited-files-save - It will open a new buffer emacs-opened-files buffer and then keep going. I’m not sure why it doesn’t work at all for you - are you using the new loading sequence?

Ok, I can confirm that even with that directory in existence that this no longer works for me.

there should be a number in greater-than/less-than signs after that last emacs-opened-files.

hmm.
This doesn’t seem to work for me any more.
it doesn’t restore my visited files, and keeps randomly asking me if I want to kill emacs-opened-files, sometimes emacs-opened-files buffers keep propagating.
emacs-opened-files etc.

I’m on a weekly snapshot of CVS emacs, and I use a number of other packages, too. Might be an interaction of those things, but the old version, while wonky at times, worked.

save-visited-files doesn’t do the same thing as recentf. Recentf lets you re-open files that you had open recently. Save-visited-files mode makes emacs automatically, at start-up, re-open every file that was open last time emacs exited (or died, or you rebooted, or whatever). It’s the simplest possible implementation of a “workspace”-type feature for emacs. There’s a single workspace, and every file is in it.

So, to summarize, it’s a continuity feature, to make it so that when you close and re-open emacs, you can more quickly get back to where you left off.

By the way, I found a useful improvement: file-precious-flag, which makes emacs take extra steps not to leave you with a half-modified file when saving. To enable it for save-visited-files, insert it into the save function like this:

(defun save-visited-files-save (&optional location)
“Save the list of currently visited files”
;(interactive)
(save-window-excursion
(setq location (or location save-visited-files-location))
(switch-to-buffer “*Save Visited*”)
(ignore-errors
(erase-buffer)
(mapcar ‘(lambda (x) (insert x “\n”))
(remove-if ‘(lambda (x)
(or (string-equal location x)
(eq nil x))) (mapcar ‘buffer-file-name (buffer-list))))
(let ((file-precious-flag t))
(write-file location nil))
(kill-buffer (get-buffer “*Save Visited*”))))

I keep getting asked if I want to kill emacs-opened-files, at seemingly random intervals.

What does it offer over recentf-mode ?
