The minitar library is a pure-Ruby library that provides the ability to deal with POSIX tar(1) archive files.
This is release 0.6, …
minitar (previously called Archive::Tar::Minitar) is based heavily on code originally written by Mauricio Julio Fernández Pradier for the rpa-base project.
Using minitar is easy. The simplest case is:
require 'zlib' require 'minitar' # Packs everything that matches Find.find('tests'). # test.tar will automatically be closed by Minitar.pack. Minitar.pack('tests', File.open('test.tar', 'wb')) # Unpacks 'test.tar' to 'x', creating 'x' if necessary. Minitar.unpack('test.tar', 'x')
A gzipped tar can be written with:
# test.tgz will be closed automatically.
Minitar.pack('tests', Zlib::GzipWriter.new(File.open('test.tgz', 'wb'))
# test.tgz will be closed automatically.
Minitar.unpack(Zlib::GzipReader.new(File.open('test.tgz', 'rb')), 'x')
As the case above shows, one need not write to a file. However, it will sometimes require that one dive a little deeper into the API, as in the case of StringIO objects. Note that I’m not providing a block with Minitar::Output, as Minitar::Output#close automatically closes both the Output object and the wrapped data stream object.
begin sgz = Zlib::GzipWriter.new(StringIO.new("")) tar = Output.new(sgz) Find.find('tests') do |entry| Minitar.pack_file(entry, tar) end ensure # Closes both tar and sgz. tar.close end
The minitar library uses a Semantic Versioning scheme with one change:
-
When PATCH is zero (
0), it will be omitted from version references.
