UNIVERSAL::exports - Lightweight, universal exporting of variables
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 $This and &That.
This is an alternative to Exporter intended to provide a universal, lightweight subset of its functionality. It uses Exporter::Lite, so look there for details. Additionally, "exports()" is provided to find out what symbols a module exports. UNIVERSAL::exports places its methods in the UNIVERSAL namespace, so there is no need to subclass from it.
UNIVERSAL::exports has two public methods, import() derived from Exporter::Lite, and exports(). import Some::Module->import; Some::Module->import(@symbols); This is Exporter::Lite's import() method. Look in Exporter::Lite for details. exports @exported_symbols = Some::Module->exports; Some::Module->exports($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.
'"%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 $@% salad wasn't recognized).
