The Exporter module implements an import method which allows a module to export functions and variables to its users' namespaces. Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimised for the common case.
Introduction
The Exporter module implements an import method which allows a module to export functions and variables to its users' namespaces.
Many modules use Exporter rather than implementing their own import method because Exporter provides a highly flexible interface, with an implementation optimised for the common case.
Perl automatically calls the import method when processing a use statement for a module. Modules and use are documented in perlfunc and perlmod. Understanding the concept of modules and how the use statement operates is important to understanding the Exporter.
Usage
The arrays @EXPORT and @EXPORT_OK in a module hold lists of symbols that are going to be exported into the users name space by default, or which they can request to be exported, respectively.
The symbols can represent functions, scalars, arrays, hashes, or typeglobs. The symbols must be given by full name with the exception that the ampersand in front of a function is optional, e.g.
