Dired under VC
The VC Dired Mode described here works with all the version control
systems that VC supports. Another more powerful facility, designed
specifically for CVS, is called PCL-CVS. See About PCL-CVS.
When you are working on a large program, it is often useful to find
out which files have changed within an entire directory tree, or to view
the status of all files under version control at once, and to perform
version control operations on collections of files. You can use the
command C-x v d (vc-directory) to make a directory listing
that includes only files relevant for version control.
C-x v d creates a buffer which uses VC Dired Mode. This looks
much like an ordinary Dired buffer (see Dired); however, normally it
shows only the noteworthy files (those locked or not up-to-date). This
is called terse display. If you set the variable
vc-dired-terse-display to nil, then VC Dired shows all
relevant files--those managed under version control, plus all
subdirectories (full display). The command v t in a VC
Dired buffer toggles between terse display and full display (see VC Dired Commands).
By default, VC Dired produces a recursive listing of noteworthy or
relevant files at or below the given directory. You can change this by
setting the variable vc-dired-recurse to nil; then VC
Dired shows only the files in the given directory.
The line for an individual file shows the version control state in the
place of the hard link count, owner, group, and size of the file. If
the file is unmodified, in sync with the master file, the version
control state shown is blank. Otherwise it consists of text in
parentheses. Under RCS and SCCS, the name of the user locking the file
is shown; under CVS, an abbreviated version of the cvs status
output is used. Here is an example using RCS:
/home/jim/project:
-rw-r--r-- (jim) Apr 2 23:39 file1
-r--r--r-- Apr 5 20:21 file2
The files file1 and file2 are under version control,
file1 is locked by user jim, and file2 is unlocked.
Here is an example using CVS:
/home/joe/develop:
-rw-r--r-- (modified) Aug 2 1997 file1.c
-rw-r--r-- Apr 4 20:09 file2.c
-rw-r--r-- (merge) Sep 13 1996 file3.c
Here file1.c is modified with respect to the repository, and
file2.c is not. file3.c is modified, but other changes
have also been checked in to the repository--you need to merge them
with the work file before you can check it in.
When VC Dired displays subdirectories (in the "full" display mode),
it omits some that should never contain any files under version control.
By default, this includes Version Control subdirectories such as
RCS and CVS; you can customize this by setting the
variable vc-directory-exclusion-list.
You can fine-tune VC Dired's format by typing C-u C-x v d--as in
ordinary Dired, that allows you to specify additional switches for the
ls command.
