188.8.131.52 Registering a File for Version Control
You can put any file under version control by simply visiting it, and
then typing C-x v i (
- C-x v i
- Register the visited file for version control.
To register the file, Emacs must choose which version control system
to use for it. If the file's directory already contains files
registered in a version control system, Emacs uses that system. If
there is more than one system in use for a directory, Emacs uses the one
that appears first in
vc-handled-backends (see Customizing VC).
On the other hand, if there are no files already registered,
Emacs uses the first system from
vc-handled-backends that could
register the file (for example, you cannot register a file under CVS if
its directory is not already part of a CVS tree); with the default
vc-handled-backends, this means that Emacs uses RCS in
If locking is in use, C-x v i leaves the file unlocked and
read-only. Type C-x v v if you wish to start editing it. After
registering a file with CVS, you must subsequently commit the initial
version by typing C-x v v. Until you do that, the version
appears as ‘@@’ in the mode line.
The initial version number for a newly registered file is 1.1, by
default. You can specify a different default by setting the variable
vc-default-init-version, or you can give C-x v i a numeric
argument; then it reads the initial version number for this particular
file using the minibuffer.
vc-initial-comment is non-
nil, C-x v i reads an
initial comment to describe the purpose of this source file. Reading
the initial comment works like reading a log entry (see Log Buffer).
