VCS - Library for generic Version Control System access in Perl

    use VCS;
    $file = VCS::File->new($ARGV[0]);
    print $file->url, ":\n";
    for $version ($file->versions) {
        print $version->version,
              ' was checked in by ',
              $version->author,
              "\n";
    }

CWVCS is an API for abstracting access to all version control systems from Perl code. This is achieved in a similar fashion to the CWDBI suite of modules. There are container classes, CWVCS::Dir, CWVCS::File, and CWVCS::Version, and implementation classes, such as CWVCS::Cvs::Dir, CWVCS::Cvs::File, and CWVCS::Cvs::Version, which are subclasses of their respective container classes.

The container classes are instantiated with URLs. There is a URL scheme for entities under version control. The format is as follows:

    vcs://localhost/VCS::Cvs/fs/path/?query=1

The query part is ignored for now. The path must be an absolute path, meaningful to the given class. The class is an implementation class, such as CWVCS::Cvs.

The container classes work as follows: when the CWnew method of a container class is called, it will parse the given URL, using the CWVCS->parse_url method. It will then call the CWnew of the implementation's appropriate container subclass, and return the result. For example,

    VCS::Version->new('vcs://localhost/VCS::Cvs/fs/path/file/1.2');

will return a CWVCS::Cvs::Version.

An implementation class is recognised as follows: its name starts with CWVCS::, and CWrequire "VCS/Classname.pm" will load the appropriate implementation classes corresponding to the container classes.

This returns a four-element list:

    ($hostname, $classname, $path, $query)

For example,

    VCS->parse_url('vcs://localhost/VCS::Cvs/fs/path/file/1.2');

will return

    (
        'localhost',
        'VCS::Cvs',
        '/fs/path/file/1.2',
        ''
    )

This is mostly intended for use by the container classes, and its interface is subject to change.

This loads its given implementation class.

Please refer to the documentation for VCS::Dir, VCS::File, and VCS::Version; as well as the implementation specific documentation as in VCS::Cvs, VCS::Rcs.

Much of this information is incorrect, the current up to date version of VCS is held on a different CVS server now, i'm going to make things a little more public and then update the below information - thanks for your patience.

VCS.pm and its friends are available from CPAN. There is a web page at:

as well as a sourceforge project page at:

    http://sourceforge.net/projects/vcs/

There is currently a mailing list about VCS. Go to the following webpage to subscribe to it:

There is a web archive of the mailing list at:

General queries should be made directly to the mailing list.
