Usage

    use Arch::Tarball
    my $tarball = Arch::Tarball->new;
    my $pipe = $tarball->create(

        base_name => 'new-subdir-to-pack',
        pipe => 1,
    );

Overview

Arch::Tarball provides an object oriented interface to work with (create, examine or extract) standard gzipped tarballs.

Note: As functionality is added only when needed, a lot of features are currently not implemented.

Methods

The following functions are available:

new, create, extract, list.

new %opts

Creates a new Arch::Tarball object.

The following parameters can be set via %opts:

tar

The name of the tar executable. Defaults to "tar".

file

The filename of the Tarball.

create %opts

Creates a new tarball (tar.gz) from a given directory structure.

create understands the following options:

dir (mandatory)

Specifies the base directory for the tarball. The given directory and recursively its content will be added to the tarball. The directory's basename will be used as the first and the only subdirectory in the tarball.

base_name

Allow the programmer to specify a different base directory name for the tarball content than the basename of dir. In this case, 'cp' process is launched to temporarily rename the last element of dir.

pipe

When set, create does not create a physical tarball but writes the tarballs content to a newly created pipe. The pipe is returned by the create method.

Note: Currently the pipe option is mandatory.

extract %opts

Extracts the tarball to a given target directory, specified by dir option. If dir option is not given, a temporary directory is created that will hold the extracted dirs/files. This directory is returned.

The file option specifies the tarball file name. It may be given in the constructor instead.

list %opts (not implemented yet)

Returns a list of files and directories in the tarball.
