NAME Gentoo::Overlay - Tools for working with Gentoo Overlays VERSION version 2.001001 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 ( $context_information ) = shift; } ); The iterate method provides a handy way to do walking across the whole tree stopping at each of a given type. * "$what = 'categories'" $overlay->iterate( categories => sub { my ( $self, $c ) = shift; # $c->{category_name} # String # $c->{category} # Category Object # $c->{num_categories} # How many categories are there to iterate # $c->{last_category} # Index ID of the last category. # $c->{category_num} # Index ID of the current category. } ); * "$what = 'packages'" $overlay->iterate( packages => sub { my ( $self, $c ) = shift; # $c->{category_name} # String # $c->{category} # Category Object # $c->{num_categories} # How many categories are there to iterate # $c->{last_category} # Index ID of the last category. # $c->{category_num} # Index ID of the current category. # # $c->{package_name} # String # See ::Category for the rest of the fields provided by the package Iterator. # Very similar though. } ); * "$what = 'ebuilds'" $overlay->iterate( ebuilds => sub { my ( $self, $c ) = shift; # $c->{category_name} # String # $c->{category} # Category Object # $c->{num_categories} # How many categories are there to iterate # $c->{last_category} # Index ID of the last category. # $c->{category_num} # Index ID of the current category. # # $c->{package_name} # String # See ::Category for the rest of the fields provided by the package Iterator. # Very similar though. # # $c->{ebuild_name} # String # See ::Package for the rest of the fields provided by the ebuild Iterator. # Very similar though. } ); ATTRIBUTES path Path to repository. isa => File, ro, required, coerce "File" in Types::Path::Tiny name Repository name. isa => Gentoo__Overlay_RepositoryName, ro, lazy_build "RepositoryName" "_build_name" ATTRIBUTE ACCESSORS category_names Returns a list of the names of all the categories. my @list = sort $overlay->category_names(); "_categories" categories Returns a hash of "Category" objects. my %hash = $overlay->categories; print $hash{dev-perl}->pretty_name; # dev-perl/::gentoo "_categories" get_category Returns a Category Object for a given category name my $cat = $overlay->get_category('dev-perl'); "_categories" PRIVATE ATTRIBUTES _profile_dir Path to the profile sub-directory. isa => Dir, ro, lazy_build "Dir" in MooseX::Types::Path::Tiny "_build__profile_dir" _categories The auto-generating category hash backing isa => HashRef[ Gentoo__Overlay_Category ], ro, lazy_build "_build__categories" "_has_category" "category_names" "categories" "get_category" "Gentoo__Overlay_Category" in Gentoo::Overlay::Types "MooseX::Types::Moose" PRIVATE ATTRIBUTE ACCESSORS _has_category Returns if a named category exists $overlay->_has_category("dev-perl"); "_categories" PRIVATE CLASS ATTRIBUTES _default_paths Class-wide list of path generators. isa => HashRef[ CodeRef ], ro, lazy_build "_build__default_paths" PRIVATE METHODS _build_name Extracts the repository name out of the file '"repo_name"' in "$OVERLAY/profiles/repo_name" $overlay->_build_name "name" _build__profile_dir Verifies the existence of the profile directory, and returns the path to it. $overlay->_build__profile_dir "_profile_dir" _build__categories Generates the Category Hash-Table, either by reading the categories index ( new, preferred ) or by traversing the directory ( old, discouraged ) $category->_build_categories; "_categories" "_build___categories_scan" "_build___categories_file" _build___categories_file Builds the category map using the 'categories' file found in the overlays profile directory. $overlay->_build___categories_file _build___categories_scan Builds the category map the hard way by scanning the directory and then skipping things that are files and/or blacklisted. $overlay->_build___categories_scan _iterate_ebuilds $object->_iterate_ebuilds( ignored_value => sub { } ); Handles dispatch call for $object->iterate( ebuilds => sub { } ); _iterate_categories $object->_iterate_categories( ignored_value => sub { } ); Handles dispatch call for $object->iterate( categories => sub { } ); _iterate_packages $object->_iterate_packages( ignored_value => sub { } ); Handles dispatch call for $object->iterate( packages => sub { } ); AUTHOR Kent Fredric COPYRIGHT AND LICENSE This software is copyright (c) 2014 by Kent Fredric .
