DESCRPITON

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.

OPTIONS

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.

INSTALLATION

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

METHODS

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.

meta

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

intuit_license

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

update_manifest

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

ebuild_source

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.

DEPENDENCIES
