NAME

       Specio::Exporter - Base class for type libraries

VERSION

       version 0.42

SYNOPSIS

           package MyApp::Type::Library;

           use parent 'Specio::Exporter';

           use Specio::Declare;

           declare( ... );

           # more types here

           package MyApp::Foo;

           use MyApp::Type::Library

DESCRIPTION

       Inheriting from this package makes your package a type exporter. By default, types defined
       in a package are never visible outside of the package. When you inherit from this package,
       all the types you define internally become available via exports.

       The exported types are available through the importing package's "t" subroutine.

       By default, types your package imports are not re-exported:

         package MyApp::Type::Library;

         use parent 'Specio::Exporter';

         use Specio::Declare;
         use Specio::Library::Builtins;

       In this case, the types provided by Specio::Library::Builtins are not exported to packages
       which "use MyApp::Type::Library".

       You can explicitly ask for types to be re-exported:

         package MyApp::Type::Library;

         use parent 'Specio::Exporter';

         use Specio::Declare;
         use Specio::Library::Builtins -reexport;

       In this case, packages which "use MyApp::Type::Library" will get all the types from
       Specio::Library::Builtins as well as any types defined in "MyApp::Type::Library".

ADDITIONAL EXPORTS

       If you want to export some additional subroutines from a package which has
       "Specio::Exporter" as its parent, define a sub named "_also_export". This sub should
       return a list of subroutines defined in your package that should also be exported. These
       subs will be exported unconditionally to any package that uses your package.

COMBINING LIBRARIES WITH Specio::Subs

       You can combine loading libraries with subroutine generation using Specio::Subs by using
       "_also_export" and "Specio::Subs::subs_installed_into":

           package My::Library;

           use My::Library::Internal -reexport;
           use Specio::Library::Builtins -reexport;
           use Specio::Subs qw( My::Library::Internal Specio::Library::Builtins );

           sub _also_export {
               return Specio::Subs::subs_installed_into(__PACKAGE__);
           }
