Arch::Inventory(3pm) User Contributed Perl Documentation Arch::Inventory(3pm)NAMEArch::Inventory - class representing a tree inventorySYNOPSISuse Arch::Inventory qw(:category :type); my $inv = Arch::Inventory->new; # use cwd print Arch::Inventory->to_string($inv->get_root_entry), " "; print $inv->get_listing; or (most commonly): use Arch::Tree; my $tree = Arch::Tree->new; my $inv = $tree->get_inventory; print $inv->get_listing;DESCRIPTIONArch::Inventory generates a tree inventory. An inventory is a tree structure of elements, each representing a single directory entry of the source tree. Each inventory entry is described by an hash with the following fields: category The classification of the tree element. category can be one of TREE, SOURCE, PRECIOUS, BACKUP or JUNK. untagged A boolean value indicating whether the element was first classified as SOURCE but lacked an inventory id. type The tree element type. type can be one of FILE, DIRECTORY or SYMLINK. path The complete path to the tree element relative to the inventory base directory. id The elements inventory id. May be "undef". children A hash of the elements direct children, idexed by their last path element. This field exists for elements of type DIRECTORY only. The category and type constants can be conveniently imported using the tags ":category" and ":type". use Arch::Inventory qw(:category :type);METHODSThe following methods are available: new, directory, get_root_entry, get_entry, get_listing, annotate_fs, foreach, dump, to_string. new [$dir] Create an inventory for $dir or the current directory if $dir is not specified. directory Returns the inventories base directory as passed to new. get_root_entry Returns the inventory element for the base directory. The root entry always has the following properties: $root = { category => TREE, # if {arch} exists, SOURCE otherwise untagged => 1, type => DIRECTORY, path => '', id => undef, children => { ... }, } get_entry $path get_entry @path_elements Returns the inventory element for the specified path. The path may either be given as a single string or as a list of path elements. If the element does not exist "undef" is returned. Using an empty or no path is equivalent to calling get_root_entry. get_listing Generates a textual inventory listing equivalent to the output of tla inventory -tspbju -B --kind --ids --untagged Note: The output order is not equivalent to tla. Instead of strict ASCII order of path names, a directory entry is always directly followed by its child entries. Entries with the same parent entry are ASCII ordered. annotate_fs annotate_fs $entry Add filesystem information to $entry or every inventory entry if none is provided. This adds the fields stat and symlink to the annotated entries which contain the output of lstat and readlink respectively. foreach $coderef Execute $coderef for every inventory entry, passing the entry as $_[0]. dump Generates a dump of the inventory structure using Data::Dumper. to_string $inventory_element Generates an inventory line for the inventory element as produced by tla.BUGSAwaiting for your reports.AUTHORSMikhael Goikhman (migo@homemail.com--Perl-GPL/arch-perl--devel).
