NAME
Archive::Libarchive::Peek - Peek into archives without extracting them
VERSION
version 0.04
SYNOPSIS
use Archive::Libarchive::Peek;
my $peek = Archive::Libarchive::Peek->new( filename => 'archive.tar' );
my @files = $peek->files();
my $contents = $peek->file('README.txt')
DESCRIPTION
This module lets you peek into archives without extracting them. It is
based on Archive::Peek, but it uses Archive::Libarchive, and thus all
of the many formats supported by libarchive. It also supports some
unique features of the various classes that use the "Peek" style
interface:
Many Many formats
compressed tar, Zip, RAR, ISO 9660 images, etc.
Zips with encrypted entries
You can specify the passphrase or a passphrase callback with the
constructor
Multi-file RAR archives
If filename is an array reference it will be assumed to be a list of
filenames representing a single multi-file archive.
CONSTRUCTOR
new
my $peek = Archive::Libarchive::Peek->new(%options);
This creates a new instance of the Peek object. One of the "filename"
or "memory" option
filename
my $peek = Archive::Libarchive::Peek->new( filename => $filename );
The filename of the archive to read from.
memory
[version 0.03]
my $peek = Archive::Libarchive::Peek->new( memory => \$content );
A reference to the memory region containing the archive. Passing in a
plain scalar will throw an exception.
passphrase
my $peek = Archive::Libarchive::Peek->new( passphrase => $passphrase );
my $peek = Archive::Libarchive::Peek->new( passphrase => sub {
...
return $passphrase;
});
This option is the passphrase for encrypted zip entries, or a
callback which will return the passphrase.
PROPERTIES
filename
This is the archive filename for the Peek object. This will be undef
for in-memory archives.
METHODS
files
my @files = $peek->files;
This method returns the filenames of the entries in the archive.
file
my $content = $peek->file($filename);
This method files the filename in the archive and returns its content.
iterate
$peek->iterate(sub ($filename, $content, $e) {
...
});
This method iterates over the entries in the archive and calls the
callback for each entry. The arguments are:
filename
The filename of the entry
content
The content of the entry, or '' for non-regular or zero-sized files
entry
This is a Archive::Libarchive::Entry instance which has metadata
about the file, like the permissions, timestamps and file type.
as_hash
[version 0.02]
my $hashref = $peek->as_hash;
Returns a hash reference where the keys are entry pathnames and the
values are the entry content. This method will attempt to resolve
symbolic links as scalar references. Hardlinks will be reference
aliased. Directory and other special types will be handled as array
reference, the exact format to be determined in the future, although
the first element in the array reference will be the file type.
SEE ALSO
Archive::Peek
The original!
Archive::Peek::External
Another implementation that uses external commands to peek into
archives
Archive::Peek::Libarchive
Another implementation that also relies on libarchive, but doesn't
support the file type in iterate mode, encrypted zip entries, or
multi-file RAR archives.
Archive::Libarchive
A lower-level interface to libarchive which can be used to
read/extract and create archives of various formats.
