NAME

Dist::Zilla::Plugin::DualLife - Distribute dual-life modules with Dist::Zilla

SYNOPSIS

In your dist.ini:

  [DualLife]

DESCRIPTION

Dual-life modules, which are modules distributed both as part of the perl core and on CPAN, sometimes need a little special treatment. This module tries provide that for modules built with Dist::Zilla.

Currently the only thing this module does is providing an INSTALLDIRS option to ExtUtils::MakeMaker's WriteMakefile function, so dual-life modules will be installed in the right section of @INC depending on different versions of perl.

As more things that need special handling for dual-life modules show up, this module will try to address them as well.

The options added to your Makefile.PL by this module are roughly equivalent to:

    'INSTALLDIRS' => ($] >= 5.009005 && $] <= 5.011000 ? 'perl' : 'site'),

If the module didn't enter core in 5.009005, set the entered_core attribute appropriately:

    [DualLife]
    entered_core=5.006001

ATTRIBUTES

entered_core

Indicates when the distribution joined core. Defaults to 5.009005 for all the things that came in for 5.10.

eumm_bundled

Boolean for distributions bundled with ExtUtils::MakeMaker. Prior to v5.12, bundled modules might get installed into the core library directory, so even if they didn't come into core until later, they need to be forced into core prior to v5.12 so they take precedence.

ACHTUNG!

• This module is a really gross hack

  To do the things it does properly, Dist::Zilla's MakeMaker plugin would first have to be reworked a lot. If and whenever that happens, this module will be adapted accordingly and maybe stop being so horribly wrong.

• Only ExtUtils::MakeMaker is supported

  If you decide to use an install tool other than ExtUtils::MakeMaker, this module will NOT work. However, that's only because I happen to use ExtUtils::MakeMaker only. If you prefer using Module::Build or something else instead and want to use this plugin with it, I'd be very to apply patches to make it work with those other install tools.

• Only works with Makefile.PLs generated by Dist::Zilla::Plugin::MakeMaker

  This module rewrites the contents of an existing Makefile.PL to insert additional options. The heuristics it currently uses for that depend on the conventions currently used in Makefile.PLs generated with Dist::Zilla::Plugin::MakeMaker. If those change, this module will break. However, I'll do my best to update this plugin if that ever happens.

  Hopefully we'll have a more extensible MakeMaker plugin at some point, so all these issues will go away.
