Exporter is a Perl module that implements default import method for modules.

SYNOPSIS

In module YourModule.pm:

package YourModule;
require Exporter;
@ISA = qw(Exporter);
@EXPORT_OK = qw(munge frobnicate); # symbols to export on request

or

package YourModule;
use Exporter 'import'; # gives you Exporter's import() method directly
@EXPORT_OK = qw(munge frobnicate); # symbols to export on request

In other files which wish to use YourModule:

use ModuleName qw(frobnicate); # import listed symbols
frobnicate ($left, $right) # calls YourModule::frobnicate

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.
