NAME

       Config::MVP::Assembler::WithBundles - a role to make assemblers expand bundles

VERSION

       version 2.200002

DESCRIPTION

       Config::MVP::Assembler::WithBundles is a role to be composed into a Config::MVP::Assembler subclass.  It allows some sections of
       configuration to be treated as bundles.	When any section is ended, if that section represented a bundle, its bundle contents will be
       unrolled and will replace it in the sequence.

       A package is considered a bundle if the this returns a defined method:

	 my $method = $assembler->package_bundle_method($package);

       The default implementation looks for a method callde "mvp_bundle_config", but "package_bundle_method" can be replaced to allow for other
       bundle-identifying information.

       Bundles are expanded by a call to the assembler's "replace_bundle_with_contents" method, like this:

	 $assembler->replace_bundle_with_contents($section, $method);

   replace_bundle_with_contents
       The default "replace_bundle_with_contents" method deletes the section from the sequence.  It then gets a description of the new sections to
       introduce, like this:

	 my @new_config = $bundle_section->package->$method({
	   name    => $bundle_section->name,
	   package => $bundle_section->package,
	   payload => $bundle_section->payload,
	 });

       (We pass a hashref rather than a section so that bundles can be expanded synthetically without having to laboriously create a new Section.)

       The returned @new_config is a list of arrayrefs, each of which has three entries:

	 [ $name, $package, $payload ]

       Each arrayref is converted into a section in the sequence.  The $payload should be an arrayref of name/value pairs to be added to the
       created section.
