Specio::Exporter - Base class for type libraries
version 0.42
package MyApp::Type::Library;
use parent 'Specio::Exporter';
use Specio::Declare;
declare( ... );
# more types here
package MyApp::Foo;
use MyApp::Type::Library
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 the Specio::Library::Builtins manpage 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 the Specio::Library::Builtins manpage as well as any types defined in
MyApp::Type::Library.
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.
You can combine loading libraries with subroutine generation using
the Specio::Subs manpage 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__);
}
