scope in packages

[jez]

Hi everyone.

I am just looking for clarification on a scope issue.

I have my perl file which is writing some XML based on some inputs. I have got a whole bunch of default values in a .pm file.

For info my script is called VO_delivery.pl
and my package is called VO_delivery_xml_config.pm


In my main script i am using

use strict;
use VO_delivery_xml_config;

Then when i use a variable from the package it is in the following form:

$VO_delivery_xml_config::outputFolder;

for a variable called outputFolder

In the package file is it correct to use 'our' for the variable declaration or should i use 'my'.

I have looked at the documentation on this and i think this is the right way to do it, but not sure.

Any tips on this or even links to a good explanation of scope would be greatly appreciated.

Thanks,

Jez

Yes, 'our' is the correct way to go (hence 'our $VERSION'). If you did it with 'my', then $VO_delivery_xml_config:utputFolder wouldn't work.
