Variable question

[Raj]

Hi,

I was wondering what this means:

$opt_f = $Name::Email::Config::config_dir.'/email-config.xml'
unless $opt_f;

I've not seen the $Name::Email::Config::config_dir notation before so I was
wondering if someone could explain.

Thanks in advance for enlightening me!

Regards

It's the scalar variable $config_dir in the package Name::Email::Config.
See perldoc perldata.

Hi Anno,

That's exactly what I thought it was...however I cannot find a package
called Name::Email::Config, which is why I got confused.

I will obviously have to dig around a bit more to find out where it is!

Thanks for your help.

Hi Anno,

It doesn't have to be defined or been used for anything else. The
package is created when it doesn't exist. It wouldn't make much sense
to use a package for just a single scalar, but it's certainly possible.
