Hello Corion,

This is actually the key point of my question. I want to find a way to pass/ inherit the value to my $firstName when the module will be called.

My intention is to use warnings on my script instead of die functions and store the error on a directory.

Sample of pseudo code Employee.pm:

So my question is how to pass the $fileDirectory into %WARNS so I can use it to print the error on correct location. I can pass it as a parameter through main.pl.

Sample of new main.pl:

#!/usr/bin/perl
use Person;
use strict;
use warnings;
use Employee;

my $dirToBePassed = "/path/Dir";

my $object = new Person( "Thanos", "Test", 123456);
my $firstName = $object->getFirstName();
print "This is the first name: $firstName\n";

my $secondObject = new Employee( "refToBeUsed" );
my $solution = $secondObject->somethingCalledFromMain();
print "This is the solution : $solution\n";

Sample of new Employee.pm

#!/usr/bin/perl
use strict;
use warnings;

package Employee;

sub new
{
    my $class = shift;
    my $self = {
        refFromMain => shift,
    };
    bless $self, $class;
    return $self;
}

sub somethingCalledFromMain
{
    my( $self ) = @_;
=comment
    do something here;
    warn "I was not able to complete the process!\n";
=cut
    return $self->{refFromMain};
}

my %WARNS;
local $SIG{__WARN__} = sub {
    my $message = shift;
    return if $WARNS{$message}++;
    logger('warning', $message);
};

sub logger {
    my ($level, $msg) = @_;
    if (open my $out, '>>', 'log.txt') {
        chomp $msg;
        print $out "$level - $msg\n";
    close $out;
    }
}

Sample of working output:

This is the first name: Thanos
This is the solution : refToBeUsed

It is really easy to pass the my $dirToBePassed = "/path/Dir"; to Employee.pm as somethingCalledFromMain($dirToBePassed); with minor code modifications. The problem is how to pass this parameter to %WARNS. So I can print the warnings on the correct directory.

Thank you for your time and effort reading and replying to my question.
