How could I access the symbol table for the current package an object was instantiated in? For example, I have something like this:
my $object = MyModule->new;
# this looks in the current package, to see if there's a function named run_me
# I'd like to know how to do this without passing a sub reference
$object->do_your_job;
If in the implementation of do_your_job
I use __PACKAGE__
, it will search in the MyModule
package. How could I make it look in the right package?
EDIT:I'll try to make this clearer. Suppose I have the following code:
package MyMod;
sub new {
return bless {},$_[0]
}
sub do_your_job {
my $self = shift;
# of course find_package_of is fictional here
# just for this example's sake, $pkg should be main
my $pkg = find_package_of($self);
if(defined &{ $pkg . '::run_me' }) {
# the function exists, call it.
}
}
package main;
sub run_me {
print "x should run me.\n";
}
my $x = MyMod->new;
# this should find the run_me sub in the current package and invoke it.
$x->do_your_job;
Now, $x
should somehow notice that main
is the current package, and search it's symbol table. I tried using Scalar::Util
's blessed , but it still gave me MyModule
instead of main
. Hopefully, this is a bit clearer now.
