NAME

Doit::Deb - commands for dealing with the Debian package system

SYNOPSIS

    use Doit;
    my $doit = Doit->init;
    $doit->add_component('deb');

    $doit->deb_install_packages(qw(zsh wget aptitude));

    my @missing_packages = $doit->deb_missing_packages(qw(zsh wget aptitude));

    $doit->deb_install_key(
        url => 'http://deb.example.org/key/deb.example.org.key',
        key => '0123456789ABCDEF0123456789ABCDEF01234567',
    );

DESCRIPTION

Doit::Deb is a Doit component providing commands for dealing with debian packages. It has to be added to a script using Doit's add_component:

    $doit->add_component('deb');

DOIT COMMANDS

The following commands are added to the Doit runner object:

deb_install_packages

    $doit->deb_install_packages(@packages);

Make sure that the listed debian packages are installed (currently using apt-get(8)). Return a list of the packages which were actually installed during the execution of this command (or the number of packages in scalar context).

deb_missing_packages

    my @missing_packages = $doit->deb_missing_packages(@packages);

Return the packages out of @packages which are not yet installed. This is an "informational" command and runs even in dry-run mode.

deb_install_key

    $doit->deb_install_key(
        url => $url,
    );
    $doit->deb_install_key(
        keyserver => $keyserver,
        key       => $key,
    );

Make sure that the given key is installed in the apt keyring. The key can be expressed either using an $url (in which case curl(1) is used to download the key), or using a $keyserver and $key speciication (in which case apt-key(8) is used to download and install the key).

Return 1 if the key was actually installed, otherwise 0.

NOTES

Add to sources.list

To add a Debian repository to /etc/apt/sources.list.d the following approach may be used:

    chomp(my $distro = $doit->info_qx({quiet=>1},qw(lsb_release -cs)));
    if ($doit->write_binary("/etc/apt/sources.list.d", "deb http://debs.example.org $distro main\n")) {
        $doit->system(qw(apt-get update));
    }
