Module Version: 1.000001   Source   Latest Release: Directory-Iterator-XS-1.001002

NAME ^

Directory::Iterator::XS - Recursively list file contents

SYNOPSIS ^

  use Directory::Iterator::PP

  my $list = Directory::Iterator::PP->new($directory);
  while ($list->next) {
    print $list->get, "\n";
  }

DESCRIPTION ^

The module creates a list-like generator to recursively list files in a directory. The directories are scanned as the list is consumed, so only the one directory handle and a list of directories to scan are stored in memory.

METHODS

new(DIRECTORY)

Create a new instance on the specified DIRECTORY, which must be the name of an existing directory.

next

Advance to the next item. Returns 1 if there is a next item, 0 otherwise.

get

Get the current file (which must be set from a previous call to next).

prune

Prune the current diretory, so no more files are read from it. When scanning the list of files, when you get a file from a directory that you aren't interested in, calling prune will close that directory, to prevent spending time listing its contents.

As currently implemented, it's possible that some subdirectories could've been queued before the first file was seen, so it's not guaranteed that a single call to prune will always suffice. Its purpose is simply to be more efficient than continuing to read files from an unwanted directory.

show_dotfiles(ARG)

If ARG is true, hidden files & directories, those with names that begin with a . will be processed as regular files. By default, such files are skipped.
