PUBLIC METHODS

metadata

Fulfills the requirement of Dist::Zilla::Role::MetaProvider by processing results returned from $self->provides.

ATTRIBUTES / PARAMETERS

inherit_version

This dictates how to report versions.

values

• Set to "1" [default] The version defined by Dist::Zilla is the authority, and all versions discovered in packages are ignored.

• Set to "0" The version defined in the discovered class is the authority, and it is copied to the provides metadata.

( To use this feature in a performing class, see "_resolve_version" )

inherit_missing

This dictates how to react when a class is discovered but a version is not specified.

values

• Set to "1" [default] dist.ini's version turns up in the final metadata.

• Set to "0". A provide turns up in the final metadata without a version, which is permissible.

( To use this feature in a performing class, see "_resolve_version" )

meta_noindex

This dictates how to behave when a discovered class is also present in the no_index META field.

values

• Set to "0" [default]

  no_index META field will be ignored

• Set to "1"

  no_index META field will be recognised and things found in it will cause respective packages to not be provided in the metadata.

PERFORMS ROLES

MetaProvider

Dist::Zilla::Role::MetaProvider

REQUIRED METHODS FOR PERFORMING ROLES

provides

Must return an array full of Dist::Zilla::MetaProvides::ProvideRecord instances.

PRIVATE METHODS

_resolve_version

This is a utility method to make performing classes life easier in adhering to user requirements.

    my $params  = {
        file => $somefile ,
        $self->_resolve_version( $version );
    }

is the suggested use.

Returns either an empty list, or a list with ('version', $version );

This is so { version => undef } does not occur in the YAML.

_try_regen_metadata

This is a nasty hack really, to work around the way Dist::Zilla handles metaproviders, which result in meta-data being inaccessible to metadata Plugins.

  my $meta  = $object->_try_regen_metadata()

This at present returns metadata provided by MetaNoIndex ( if present ) but will be expanded as needed.

If you have a module you think should be in this list, contact me, or file a bug, I'll do my best ☺

_apply_meta_noindex

This is a utility method to make performing classes life easier in skipping no_index entries.

  my @filtered_provides = $self->_apply_meta_noindex( @provides )

is the suggested use.

Returns either an empty list, or a list of ProvideRecord's

THANKS

• Thanks to David Golden ( xdg / DAGOLDEN ) for the suggestion of the no_index feature for compatibility with MetaNoIndex plugin.
