Dist::Zilla::Plugin::MetaProvides(3) Generating and Populating 'provides' in your META.yml


version 2.001011


This module is not intended to be used directly, but instead, one of the following sub-modules should be used in your projects dist.ini

The most common usage should find


Sufficient for indexing traditional Perl5 modules.

Advanced Usage:

    ; Traditional Perl5 Modules
    inherit_version = 0    ;optional flag
    inherit_missing = 0    ;optional flag
    meta_noindex    = 1    ;optional flag
    ; If using MooseX::Declare style "class" keywords.
    inherit_version = 0    ;optional flag
    inherit_missing = 0    ;optional flag
    meta_noindex    = 1    ;optional flag
    ; Hand Constructed Provides in an external file
    inherit_version = 0     ;optional flag
    inherit_missing = 0     ;optional flag
    file = some_file.ini    ;mandatory flag
    reader_name = Config::INI::Reader ;optional flag
    meta_noindex    = 1     ;optional and useless flag

And then in some_file.ini

    file = lib/Imaginary/Package.pm ;mandatory flag
    version = 3.1415                ;optional flag, subject to rules in dist.ini


This Distribution Contains a small bundle of plugins for various ways of populating the "META.yml" that is built with your distribution.

The initial reason for this is due to stuff that uses MooseX::Declare style class definitions not being parseable by many tools upstream, so this is here to cover this problem by defining it in the metadata.



Scans Dist::Zilla's ".pm" files and tries to identify classes using Class::Discover.



Scans Dist::Zilla's ".pm" files and tries to identify more traditional packages using a combination of Module::Extract::VERSION and Module::Extract::Namespaces.



In the event both of the above don't work for your needs, pull in hand-crafted metadata from a specified file.




At the time this plugin runs to collect metadata from files, the mungers won't have run yet to inject custom versions into files in the various locations.

If you want the versions reported in the "provides" list to be consistent with the ones actually in the files, you will need to use this option in its enabled state.

IE: Generally, if you are using version munging, you WILL want this flag set to 1.


  • '0'

    Do not inherit version from "Dist::Zilla"

  • '1' [default]

    Inherit version from Dist::Zilla

``inherit_version'' in Dist::Zilla::Role::MetaProvider::Provider


If for whatever reason you want to actually use the versions found in the modules where present, and fall back to the value from Dist::Zilla.

"inherit_version" will need to be turned off (0) for this to be effective.


  • '0'

    Do not inherit version from "Dist::Zilla" when one is missing.

  • '1' [default]

    Inherit version from Dist::Zilla when one is missing.

``inhert_missing'' in Dist::Zilla::Role::MetaProvider::Provider


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


  • '0' [default]

    "no_index" META field will be ignored

  • '1'

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

``meta_noindex'' in Dist::Zilla::Role::MetaProvider::Provider


( Dist::Zilla::Plugin::MetaProvides::FromFile )

This is a mandatory parameter that points to the file that contains manually ( or otherwise ) crafted metadata to be integrated into your final META.yml

File Must exist.


( Dist::Zilla::Plugin::MetaProvides::FromFile )

This parameter is by default Config::INI::Reader, but it can be in fact anything that meets the following criteria.

  • Can be initialized an instance of
  • has a read_file method on the instance
  • read_file can take the parameter 'file'
  • read_file can return a hashref matching the following structure

        { 'Package::Name' => {
            'file' => '/path/to/file',
            'version' => 0.1,
