in reply to testing in perl: main and caller

I'm not sure if this is what chromatic suggested, but either one of these should do what you're looking for:
unless ( defined caller ) { #code here }
sub do_me { #code to run here } do_me unless defined caller;
sub do_me or the block after unless won't be executed when used or required, but will be executed from the command line.

From perldoc caller:

Returns the context of the current subroutine call. In scalar context, returns the caller's package name if there is a caller, that is, if we're in a subroutine or eval or require, and the undefined value otherwise.

    That's basically what the book suggests. Thanks!

      what does the test code look like, then?
      isn't correct, clearly.


        The book has:

        ok( require( '' ), 'loaded file successfully' ) or exit;

        I think require_ok() would also work, though I'm not in a position to try it right now, nor do I remember if I wrote it as above for a specific reason.
