Config::MVP::AssemblerUsertContributed PConfig::MVP::Assembler::WithBundles(3)NAMEConfig::MVP::Assembler::WithBundles - a role to make assemblers expand
bundles
VERSION
version 2.200002
DESCRIPTIONConfig::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.
