VCS::Dir(3pm)

VCS::Dir - module for access to a VCS directory

    use VCS;
    my $d = VCS::Dir->new($url);
    print $d->url . "\n";
    foreach my $x ($d->content) {
        print "\t" . $x->url . "\t" . ref($x) . "\n";
    }

"VCS::Dir" abstracts access to a directory under version control. Methods marked with a "*" are not yet finalised/implemented.
VCS::Dir->create_new($url) * $url is a file-container URL. Creates data as appropriate to convince the VCS that there is a file-container, and returns an object of class "VCS::Dir", or throws an exception if it fails. This is a pure virtual method, which must be over-ridden, and cannot be called directly in this class (a "die" will result).
VCS::Dir->introduce($name, $create_class) * $name is a file or directory name, absolute or relative. $create_class is either "File" or "Dir", and implementation classes are expected to use something similar to this code, to call the appropriate create_new:

    sub introduce {
        my ($class, $name, $create_class) = @_;
        my $call_class = $class;
        $call_class =~ s/[^:]+$/$create_class/;
        return $call_class->create_new($name);
    }

This is a pure virtual method, which must be over-ridden, and cannot be called directly in this class (a "die" will result).
VCS::Dir->new($url) $url is a file-container URL. Returns an object of class "VCS::Dir", or throws an exception if it fails. Normally, an override of this method will call "VCS::Dir->init($url)" to make an object, and then add to it as appropriate.
VCS::Dir->init($url) $url is a file-container URL. Returns an object of class "VCS::Dir". This method calls "VCS->parse_url" to make sense of the URL.
$dir->tags * THIS METHOD WORKS RECURSIVELY ON THE DIRECTORY AT HAND * Returns all the tags inside a directory and a little bit more information. The actual datstructure is a hash of hashes. The first level hash is a hash keyed on tag names, in other words it lists as its keys every single tag name in or below a directory. Each of these tag names point to another hash with has filenames as keys and version numbers as values.
$dir->url Returns the $url argument to "new".
$dir->content Returns a list of objects, either of class "VCS::Dir" or "VCS::File", corresponding to files and directories within this directory.
$dir->path Returns the absolute path of the directory.
$dir->read_dir($dir) Returns the contents of the given filesystem directory. This is intended as a utility method for subclasses. VCS. This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
