NAME

Gentoo::Overlay::Group::INI - Load a list of overlays defined in a configuration file.

VERSION

version 0.2.2

SYNOPSIS

Generates a Gentoo::Overlay::Group object using a configuration file from your environment.

require Gentoo::Overlay::Group::INI;
my $group = Gentoo::Overlay::Group::INI->load();

Currently, the following paths are checked:

~/.config/Perl/Gentoo-Overlay-Group-INI/config.ini #  'my_dist_config' dir
~/.config/Perl/Gentoo-Overlay-Group-INI/Gentoo-Overlay-Group-INI.ini
~/.local/share/Perl/dist/Gentoo-Overlay-Group-INI/config.ini  # 'my_dist_data' dir
~/.local/share/Perl/dist/Gentoo-Overlay-Group-INI/Gentoo-Overlay-Group-INI.ini
/etc/Gentoo-Overlay-Group-INI/config.ini
/etc/Gentoo-Overlay-Group-INI/Gentoo-Overlay-Group-INI.ini

If you have set GENTOO_OVERLAY_GROUP_INI_PATH, it will be split by : and each part scanned:

$ENV{GENTOO_OVERLAY_GROUP_INI_PATH} = "/a:/b"

/a/config.ini
/a/Gentoo-Overlay-Group-INI.ini
/b/config.ini
/b/Gentoo-Overlay-Group-INI.ini

If any of the path parts start with ~/ , those parts will be expanded to your "Home" directory.

Format of the INI files is as follows:

[Overlays]
directory = /usr/portage
directory = /usr/local/portage
