NAME

UNIVERSAL::AUTHORITY - adds an AUTHORITY method to UNIVERSAL

SYNOPSIS

if (HTML::HTML5::Writer->AUTHORITY ne HTML::HTML5::Builder->AUTHORITY)
{
  warn "Closely intertwined modules with different authors!\n";
  warn "There may be trouble ahead...";
}

# Only trust STEVAN's releases
Moose->AUTHORITY('cpan:STEVAN'); # dies if doesn't match

DESCRIPTION

This module is deprecated: use UNIVERSAL::AUTHORITY::Lexical instead.

This module adds an AUTHORITY function to the UNIVERSAL package, which works along the same lines as the VERSION function. Because it is defined in UNIVERSAL, it becomes instantly available as a method for any blessed objects, and as a class method for any package.

The authority of a package can be defined like this:

package MyApp;
BEGIN { $MyApp::AUTHORITY = 'cpan:JOEBLOGGS'; }

The authority should be a URI identifying the person, team, organisation or trained chimp responsible for the release of the package. The pseudo-URI scheme cpan: is the most commonly used identifier.

UNIVERSAL::AUTHORITY

Called with no parameters returns the authority of a CPAN release.

UNIVERSAL::AUTHORITY($test)

If passed a test, will croak if the test fails. The authority is tested against the test using something approximating Perl 5.10's smart match operator. (Briefly, you can pass a string for eq comparison, a regular expression, a code reference to use as a callback, or an array reference that will be grepped.)
