Need Help??

in reply to Re: Was my module used or required?
in thread Was my module used or required?

"Why would you care?"

I'd like to know if a BEGIN block in my module is executed in the beginning of the applications execution or if it's executed later on, as a result of the module being require'd.

perldoc.com seems to have a temporary outage on the search facility. I've read the Camel but not found what I was looking for. Just hoped someone could tell me what I missed. ;-)

caller and the node you referenced to talks about how a method is called. I need to know if my module was loaded in compile time or during run time.

Thanks anyway.

Everything went worng, just as foreseen.

If you know about BEGIN{} blocks you should also know that there is not two separate compile and runtime phases. These two are interleaved. Even if neither you nor the module authors use any BEGIN blocks!

I'm afraid you'll have to rethink this. Consider this:

#!/usr/bin/perl
BEGIN {
  push @INC, '/some/directory';
  require Your::Module;
}
...

This way your module is being included as soon as at all possible, yet it's require()d, not use()d.

If you tell us what and why do you want to do differently we can come up with something. Just now my only idea is to set a variable when the script "starts". $My::Module::Runtime=1 is probably the best you can get.
