FAQ 7.25 How can I find out my current package?


This is an excerpt from the latest version perlfaq7.pod, which
comes with the standard Perl distribution. These postings aim to
reduce the number of repeated questions as well as allow the community
to review and update the answers. The latest version of the complete
perlfaq is at http://faq.perl.org .

7.25: How can I find out my current package?

    If you're just a random program, you can do this to find out what the
    currently compiled package is:

        my $packname = __PACKAGE__;

    But, if you're a method and you want to print an error message that
    includes the kind of object you were called on (which is not necessarily
    the same as the one in which you were compiled):

        sub amethod {
            my $self  = shift;
            my $class = ref($self) || $self;
            warn "called me from a $class object";
        }

--------------------------------------------------------------------

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.

If you'd like to help maintain the perlfaq, see the details in
perlfaq.pod.
