NAME
Directory::Scanner - Streaming directory scanner
VERSION
version 0.03
SYNOPSIS
# get all entries in a directory
my $stream = Directory::Scanner->for( $dir );
# get all entries in a directory recursively
my $stream = Directory::Scanner->for( $dir )
->recurse;
# get all entries in a directory recusively
# and filter out anything that is not a directory
my $stream = Directory::Scanner->for( $dir )
->recurse
->match(sub { $_->is_dir });
# ignore anything that is a . directory, then recurse
my $stream = Directory::Scanner->for( $dir )
->ignore(sub { $_->basename =~ /^\./ })
->recurse;
DESCRIPTION
This module provides a streaming interface for traversing directories. Unlike most modules that provide similar capabilities, this will not pre-fetch the list of files or directories, but instead will only focus on one thing at a time. This is useful if you have a large directory tree and need to do a lot of resource intensive work on each file.
Builders
This module uses the builder pattern to create the Directory::Scanner stream you need. If you look in the SYNOPSIS above you can see that the for
method starts the creation of a builder. All the susequent chained methods simply wrap the original stream and perform the task needed.
Streams
See the "API METHODS" section of Directory::Scanner::API::Stream.
METHODS
for($dir)
Constructs a stream for scanning the given $dir
.
concat(@streams)
This concatenates multiple streams into a single stream, and will return an instance that concats the streams together.
