This module is a CPANPLUS backend that recursively generates Gentoo ebuilds for a given package in the default overlay, updates the manifest, and even emerges it (together with its dependencies) if the user requires it.

The generated ebuilds are placed into the perl-gcpanp category. They favour depending on a virtual, on perl-core, dev-perl or perl-gcpan (in that order) rather than perl-gcpanp.

You can pass specific options to cpan2dist by using the --dist-opts command-line argument followed by a key=value pair, where key is the option name and value is what it is set to. --dist-opts can be used several times.

The valid option keys are :

• manifest
  
  A boolean that indicates whether the Manifest file should be generated by running ebuild manifest onto the generated ebuilds.
  
  Defaults to yes.
• overlay
  
  A string formatted as a space-delimited sequence of paths, that lists the different overlays in which existent ebuilds will be looked for.
  
  Defaults to the value of PORTDIR_OVERLAY as returned by emerge --info (usually /usr/local/portage).
• distdir
  
  The directory where ebuild expects to find the source tarballs. You need write permissions on this directory.
  
  Defaults to the value of DISTDIR as returned by emerge --info (usually /usr/portage/distfiles).
• keywords
  
  The valid KEYWORDS for the generated ebuilds.
  
  Defaults to the value of ACCEPT_KEYWORDS as returned by emerge --info.
• header
  
  A chunk of text that is prepended to every ebuild.
  
  Defaults to the generic Gentoo Foundation header.
• footer
  
  A chunk of text that is appended to every ebuild.
  
  Defaults to nothing.

cpan2dist itself takes other options, most notably :

• --buildprereq generates an ebuild for every dependency, even for those that are already up-to-date. Setting this option is recommended.
• --force forcefully regenerates ebuilds even if they already exist.
• --install installs the ebuilds after generating them.
• --skiptest skips tests while building, which speeds up the building process.
• --verbose shows a lot more information.

Please refer to cpan2dist documentation for a complete coverage of its abilities.

Before installing this module, you should append perl-gcpanp to your /etc/portage/categories file.

You have two ways for installing this module :

• Use the perl overlay located at http://git.overlays.gentoo.org/gitweb/?p=proj/perl-overlay.git. It contains an ebuild for CPANPLUS::Dist::Gentoo which will most likely be up-to-date given the reactivity of Gentoo's Perl herd.
• Bootstrap an ebuild for CPANPLUS::Dist::Gentoo using itself.
  
  First, make sure your system perl is 5.10 or greater, so that the CPANPLUS toolchain is available.
  
  

      $ perl -v
      This is perl 5, version 12, subversion 2 (v5.12.2)...
  
  

  
  
  perl 5.12 is the current stable Perl version in Gentoo. If you still have perl 5.8.x, you can upgrade it by running the following commands as root :
  
  

      # emerge -tv ">=dev-lang/perl-5.10"
      # perl-cleaner --all
  
  

  
  
  Then, fetch the CPANPLUS::Dist::Gentoo tarball :
  
  

      $ cd /tmp
      $ wget http://search.cpan.org/CPAN/authors/id/V/VP/VPIT/CPANPLUS-Dist-Gentoo-0.11.tar.gz
  
  

  
  
  Log in as root and unpack it in e.g. your home directory :
  
  

      # cd
      # tar xzf /tmp/CPANPLUS-Dist-Gentoo-0.11.tar.gz
      # cd CPANPLUS-Dist-Gentoo-0.11
  
  

  
  
  Bootstrap CPANPLUS::Dist::Gentoo using the bundled shell script g-cpanp :
  
  

      # perl Makefile.PL
      # make
      # PERL5LIB=blib/lib samples/g-cpanp CPANPLUS::Dist::Gentoo
  
  

  
  
  Finally, emerge the CPANPLUS-Dist-Gentoo ebuild you've just generated :
  
  

      # emerge -tv CPANPLUS-Dist-Gentoo
  
  

This module inherits all the methods from CPANPLUS::Dist::Base. Please refer to its documentation for precise information on what's done at each step.

Returns the contents of the META.yml or META.json files as parsed by Parse::CPAN::Meta.

Returns an array reference to a list of Gentoo licences identifiers under which the current distribution is released.

Updates the Manifest file for the ebuild associated to the current dist object.

Returns the source of the ebuild for the current dist object, or undef when one of the dependencies couldn't be mapped to an existing ebuild.
