Exporter::Declare::Meta(3) The meta object which stores meta-data for all


All classes that use Exporter::Declare have an associated Meta object. Meta objects track available exports, tags, and options.


$class->new( $package )
Created a meta object for the specified package. Also injects the export_meta() sub into the package namespace that returns the generated meta object.
$class->new_from_exporter( $package )
Create a meta object for a package that already uses Exporter.pm. This will not turn the class into an Exporter::Declare package, but it will create a meta object and export_meta() method on it. This si primarily used for reexport purposes.
$package = $meta->package()
Get the name of the package with which the meta object is associated.
Usually called at construction to add a package alias function to the exports.
$meta->add_export( $name, $ref )
Add an export, name should be the item name with sigil (assumed to be sub if there is no sigil). $ref should be a ref blessed as an Exporter::Declare::Export subclass.
$meta->get_export( $name )
Retrieve the Exporter::Declare::Export object by name. Name should be the item name with sigil, assumed to be sub when sigil is missing.
$meta->export_tags_push( $name, @items )
Add @items to the specified tag. Tag will be created if it does not already exist. $name should be the tag name WITHOUT -/: prefix.
@list = $meta->export_tags_get( $name )
Get the list of items associated with the specified tag. $name should be the tag name WITHOUT -/: prefix.
@list = $meta->export_tags_list()
Get a list of all export tags.
$bool = $meta->is_tag( $name )
Check if a tag with the given name exists. $name should be the tag name WITHOUT -/: prefix.
$meta->options_add( $name )
Add import options by name. These will be boolean options that take no arguments.
my @list = $meta->options_list()
$meta->arguments_add( $name )
Add import options that slurp in the next argument as a value.
$bool = $meta->is_option( $name )
Check if the specified name is an option.
$bool = $meta->is_argument( $name )
Check if the specified name is an option that takes an argument.
$meta->add_parser( $name, sub { ... })
Add a parser sub that should be associated with exports via Devel::Declare
$meta->get_parser( $name )
Get a parser by name.
$ref = $meta->get_ref_from_package( $item )
Returns a reference to a specific package variable or sub.
$meta->reexport( $package )
Re-export the exports in the provided package. Package may be an Exporter::Declare based package or an Exporter based package.
$meta->merge( $meta2 )
Merge-in the exports and tags of the second meta object.
