Module Version: v1.0.4   Source   Latest Release: Gentoo-Overlay-1.0.5

NAME ^

Gentoo::Overlay - Tools for working with Gentoo Overlays

VERSION ^

version 1.0.4

SYNOPSIS ^

  my $overlay = Gentoo::Overlay->new( path => '/usr/portage' );

  my $name       = $overlay->name();
  my %categories = $overlay->categories();

  print "Overlay $name 's categories:\n";
  for( sort keys %categories ){
    printf "%30s : %s", $_, $categories{$_};
  }

  # Overlay gentoo 's categories:
  #  .....
  #  dev-lang      : /usr/portage/dev-lang
  #  .....

There will be more features eventually, this is just a first release.

METHODS ^

default_path

Useful function to easily wrap the class-wide method with a per-object sugar.

    $overlay->default_path('profiles');
    ->
    ::Overlay->_default_paths->{'profiles'}->($overlay);
    ->
    $overlay->path->subdir('profiles')


    $overlay->default_path('category','foo');
    ->
    ::Overlay->_default_path('category')->( $overlay, 'foo' );
    ->
    $overlay->path->subdir('foo')

    $overlay->default_path('repo_name');
    ->
    ::Overlay->_default_path('repo_name')->( $overlay );
    ->
    $overlay->_profile_dir->file('repo_name')

They're class wide functions, but they need individual instances to work.

iterate

  $overlay->iterate( $what, sub {
      my ( $context_information ) = shift;

  } );

The iterate method provides a handy way to do walking across the whole tree stopping at each of a given type.
