Hi All,

I have some issues with exporting the variable from caller perl script to the package. I have written a small print function which will print the passed message on screen as well as log it to a file. This function is in a package named secondPackage.pm, the code looks like

package secondPakage;
use strict;
use vars qw($VERSION @ISA @EXPORT @EXPORT_OK %EXPORT_TAGS);
@ISA = qw(Exporter);
@EXPORT = qw( &WriteLOG );
@EXPORT_OK = qw();
%EXPORT_TAGS = ( );
our $LOGFile= "";

sub WriteLOG {                                                        
+                                                    
    my ($msg) = @_;
    my $ltime=localtime;
    $ltime=~s/\s/_/g;
    $ltime=~s/_+/_/g;
    $ltime=~s/^_|_$//;
    open my $lFD, '>>', "$LOGFile" or die "Unable to open LOG file |$L
+OGFile| for logging...$!";
    printf $lFD "\n=== __FILE__ === $ltime -> $msg\n";
    print "\n=== __FILE__ === $ltime -> $msg\n";
    close($lFD);                                                      
+                                                       
}

In the above package, $LOGFile is an global variable.

now there is a caller script called firstCaller.pl which will call the above function to write the logs like this,

#script firstCaller.pl
use secondPackage;
our $LOGFile=$ARGV[0];
WriteLOG("...Script is started...\n";
[download]

I am trying to initialize that variable like this also our $secondPackage::LOGFile=$ARGV[0]; but still no luck, it is not initializing the LOGFile variable. Also, i have one more package called masterPackage.pm which will also need to use above writeLOG function.

package masterPakage;
use strict;
use vars qw($VERSION @ISA @EXPORT @EXPORT_OK %EXPORT_TAGS);
@ISA = qw(Exporter);
@EXPORT = qw( &functions_to_be_exported );
@EXPORT_OK = qw();                                                    
+                              
%EXPORT_TAGS = ( );
blah..
blah..

WriteLOG(" i am inside masterPackage...\n";
blah..
blah..

1;

I am not sure is this the right way of exposing the variables for different packages, but instead of everytime passing the LOGFile variable to WriteLOG function, i was looking at somewhere making it global and whenever i need to write new scripts i can use this package to make sure i don't re write log function.

Please suggest...

Thanks,
ShekarKCB
