A puzzle about emacs

LaoLang_cool

After I edit a file, emacs always create a backup in the dir, that sounds very interesting, but isn't what I want, how can I disable this "smart" function?

set nobackup

you can make it smarter by setting the variable backup-directory-alist, the document says:

Post by Emacs

backup-directory-alist is a variable defined in `files.el'.
Its value is nil

Documentation:
Alist of filename patterns and backup directory names.
Each element looks like (REGEXP . DIRECTORY).  Backups of files with
names matching REGEXP will be made in DIRECTORY.  DIRECTORY may be
relative or absolute.  If it is absolute, so that all matching files
are backed up into the same directory, the file names in this
directory will be the full name of the file backed up with all
directory separators changed to `!' to prevent clashes.  This will not
work correctly if your filesystem truncates the resulting name.

For the common case of all backups going into one directory, the alist
should contain a single element pairing "." with the appropriate
directory name.

If this variable is nil, or it fails to match a filename, the backup
is made in the original file's directory.

On MS-DOS filesystems without long names this variable is always
ignored.

You can customize this variable.

In addition, I use debian3.1 sarge, and the emacs's version is emacs21, I've heard of that it could not support Chinese characters, is it the true? How can I deal this tedious thing?

It can support Chinese, if your locale is UTF-8 (That's very popular today), just type

2. apt-get install mule-ucs

复制代码

then your emacs can handle chinese well. If your locale is GB*, then maybe you should install mule-gbk or sth. else I don't know exactly.
But mule may cause emacs start a little slowly. If you use Debian etch or sid, I strongly recommend you install emacs-snapshot:

2. apt-get install emacs-snapshot-gtk

复制代码

which can handle chinese without installing any mule-*, and there's many things improved since version 21. You can also check out the source tree from Emacs's cvs reopsitory and build an emacs 22 for yourself(emacs-snapshot is version 22). However, there's a version 23 which, I think, is not as stable as version 22.

Oh, I have try it out, but it seems that it doesn't work correctly, and I really dissatisfy its speed, so now I use vim to display Chinese text.
Buy the way, I don't know my system coding, locale shows en_US, and zhcon has installed.

you may look at this to speedup your emacs

Does emacs have a default rc file? So I have no need to create different files for different users?
