Exports

Export routines from a package with names specified by caller of the package.

Synopsis

use Math::Zap::Vector vector=>'v', units=>'u';

my $x = v(1,0,0);
my $y = u();

Rather than:

my $x = Math::Zap::Vector::vector(1,0,0);
my $y = Math::Zap::Vector::units();

Description

Export routines from a package with names specified by caller of the package. The routines to be exported are defined in the exporting package Math::Zap::As: $VERSION=1.07;

use Math::Zap::Exports qw(
  vector ($$$)
  units  ()
);

A suitable sub import() is created, allowing the caller to specify:

use Math::Zap::Vector vector=>'v', units=>'u';

The caller may then refer to Math::Zap::Vector::vector() as v() and Math::Zap::Vector::units() as u().

The first routine exported is always imported by its export name unless a new name is supplied. Thus:

use Math::Zap::Vector;

and

use Math::Zap::Vector vector=>'vector';

have identical effects.

The advantage of this is approach is that it allows the importing package Math::Zap::To control the names of the exported routines in its name space $VERSION=1.07; rather than the developer of the exporting package, a facility I have not been able to discover in the standard Perl Exporter.pm.
