NAME

Exporter::Simple - Easier set-up of module exports

SYNOPSIS

  package MyExport;
  use base 'Exporter::Simple';

  our @bar : Exportable(vars) = (2, 3, 5, 7);
  our $foo : Exported(vars)   = 42;
  our %baz : Exported         = (a => 65, b => 66);

  sub hello : Exported(greet,uk)   { "hello there" }
  sub askme : Exportable           { "what you will" }
  sub hi    : Exportable(greet,us) { "hi there" }

  # meanwhile, in a module far, far away
  use MyExport qw(:greet);
  print hello();
  $baz{c} = 67;

DESCRIPTION

This module, when subclassed by a package, allows that package to define exports in a more concise way than using Exporter. Instead of having to worry what goes in @EXPORT, @EXPORT_OK and %EXPORT_TAGS, you can use two attributes to define exporter behavior. This has two advantages: It frees you from the implementation details of Exporter, and it keeps the export definitions where they belong, with the subroutines and variables.

The attributes provided by this module are:

Exported

Indicates that the associated subroutine or global variable should be automatically exported. It will also go into the :all tag (per the rules of %EXPORT_TAGS), as well as any tags you specify as options of this attribute.

For example, the following declaration

  sub hello : Exported(greet,uk)   { ... }

will cause hello() to be exported, but also be available in the tags :all, :greet and :uk.

Exportable

Is like Exported, except that the associated subroutine or global variable won't be automatically exported. It will still go to the :all tag in any case and all other tags specified as attribute options.

BUGS

If you find any bugs or oddities, please do inform the author.
