autosave/backup file problem

autosave/backup file problem

[Jannis]

Hi emacs users,


i have the problem that emacs creates

.#filename.txt

files in the directory file while working on a file. These files create 
problems when I want to automatically create Software packages of the 
parent folder.

Is there any way to tell emacs to create these files in a different 
location?


I have put the following in my .emacs file but it seems to not change 
the behaviour of the above mentioned files:


;; Put autosave files (ie #foo#) and backup files (ie foo~) in ~/.emacs.d/.
(custom-set-variables
   '(auto-save-file-name-transforms '((".*" "~/.emacs.d/autosaves/\\1" t)))
   '(backup-directory-alist '((".*" . "~/.emacs.d/backups/"))))


Thanks a lot for your help!

Jannis

Two problems:

1. custom-set-variables doesn't evaluate the value part of each argument 
list, so you shouldn't have the inner quotes.

2. Your regexp for auto-save-file-name-transforms doesn't contain any 
\\(...\\), so there's nothing for \\1 to be replaced with.  Use \\& to 
substitute the entire matched string, or write a more complex regular 
expression where \\1 picks up just the filename part of the pathname.

These are not backup or auto-save files.  These are lockfiles.  They
indicate that filename.txt is being edited by an Emacs session, so
that when another Emacs session (perhaps by another user) will visit
the same file, Emacs will warn that other user about the situation.

I don't understand what kind of problems these files could create (and
you didn't explain that).  But if you need to turn off creation of
lockfiles, set the variable create-lockfiles to a nil value.
