Is there any alias available in Perl for referencing a module name?

Question

I have multiple Perl modules. The package names seems to be big

everytime i access the functions from those modules, i need to provide something like this

&PackageName::Functionname()

is there a shortcut or alias available in Perl which can reference the packages with bigger names

Thanks

Answer 1

With Package::Alias you can alias a long package name such as Foo::Bar::Baz to baz:

use Package::Alias 'baz' => 'Foo::Bar::Baz';

baz::quux;  # Invokes Foo::Bar::Baz::quux;

Answer 2

You can call the function without the &:

PackageName::Functionname();

Also there is the exporter mechanism which exports function from a module to your default namespace:

use PackageName 'Functionname';

Functionname();
