NAME ^

VCS::File - module for access to a file under version control

SYNOPSIS ^

    use VCS;
    my $f = VCS::File->new($url);
    print $f->url . "\n";
    foreach my $v ($f->versions) {
        print "\tversion: " . $v->version . "\t" . ref($v) . "\n";
    }

DESCRIPTION ^

VCS::File abstracts access to a file under version control.

METHODS ^

Methods marked with a "*" are not yet finalised/implemented.

VCS::File->create_new($name) *

$name is a file name, absolute or relative. Creates data as appropriate to convince the VCS that there is a file, and returns an object of class VCS::File, 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 (an exception ("die") will result).

VCS::File->introduce($version_args) *

$version_args is a hash-ref, see VCS::Version for details. Implementation classes are expected to use something similar to this code, to call create_new in the right VCS::Version subclass:

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

This is a pure virtual method, which must be over-ridden, and cannot be called directly in this class (a die will result).

VCS::File->new($url)

$url is a file URL. Returns an object of class VCS::File, or throws an exception if it fails. Normally, an override of this method will call VCS::File->init($url) to make an object, and then add to it as appropriate.

VCS::File->tags()

Returns a reference to a hash that has keys that are any tags attached to the file and the values are the corresponding versions which the tags refer to.

VCS::File->tags_hash()

Cvs ONLY

Same as for ->.

VCS::File->tags_array()

Cvs ONLY

Returns an array of tags that are connected with the file, this is useful alongside tags_hash() as it allows you to inspect the order in which tags were applied.

VCS::File->init($url)

$url is a file URL. Returns an object of class VCS::File. This method calls VCS->parse_url to make sense of the URL.

$file->url

Returns the $url argument to new.

$file->versions

Returns a list of objects of class VCS::Version, in order of ascending revision number. If it is passed an extra (defined) argument, it only returns the last version as a VCS::Version.

$file->path

Returns the absolute path of the file.
