UNIVERSAL::exports(3) Lightweight, universal exporting of variables

SYNOPSIS


package Foo;
use UNIVERSAL::exports;
# Just like Exporter.
@EXPORT = qw($This &That);
@EXPORT_OK = qw(@Left %Right);
# Meanwhile, in another piece of code!
package Bar;
use Foo; # exports $This and &That.

DESCRIPTION

This is an alternative to Exporter intended to provide a universal, lightweight subset of its functionality. It uses Exporter::Lite, so look there for details.

Additionally, "exports()" is provided to find out what symbols a module exports.

UNIVERSAL::exports places its methods in the UNIVERSAL namespace, so there is no need to subclass from it.

Methods

UNIVERSAL::exports has two public methods, import() derived from Exporter::Lite, and exports().
import
  Some::Module->import;
  Some::Module->import(@symbols);

This is Exporter::Lite's import() method. Look in Exporter::Lite for details.

exports
  @exported_symbols = Some::Module->exports;
  Some::Module->exports($symbol);

Reports what symbols are exported by Some::Module. With no arguments, it simply returns a list of all exportable symbols. Otherwise, it reports if it will export a given $symbol.

DIAGNOSTICS

'"%s" is not exported by the %s module'
Attempted to import a symbol which is not in @EXPORT or @EXPORT_OK.
'Can\'t export symbol: %s'
Attempted to import a symbol of an unknown type (ie. the leading [email protected]% salad wasn't recognized).
