== Description
Ruby bindings for Libarchive.
Libarchive is a programming library that can create and read several different streaming archive formats, including most popular tar variants, several cpio formats, and both BSD and GNU ar variants.
== Support archive (from Libarchive 2.6.0)
=== reading
* gzip compression
* bzip2 compression
* compress/LZW compression
* GNU tar format (including GNU long filenames, long link names, and
sparse files)
* Solaris 9 extended tar format (including ACLs)
* Old V7 tar archives
* POSIX ustar
* POSIX pax interchange format
* POSIX octet-oriented cpio
* SVR4 ASCII cpio
* Binary cpio (big-endian or little-endian)
* ISO9660 CD-ROM images (with optional Rockridge extensions)
* ZIP archives (with uncompressed or "deflate" compressed entries)
* GNU and BSD 'ar' archives
* 'mtree' format
* lzma compression not supported
=== writing
* gzip compression
* bzip2 compression
* compress/LZW compression
* POSIX ustar
* POSIX pax interchange format
* "restricted" pax format, which will create ustar archives except for entries that require pax extensions (for long filenames, etc).
* ACLs not supported
* POSIX octet-oriented cpio
* SVR4 "newc" cpio
* shar archives
* GNU and BSD 'ar' archives

http://rubyforge.org/projects/libarchive
== Source Code

== Dependency
Libarchive/Ruby depend on Libarchive.
Please install Libarchive. (version 2.6.0 or more is recommended)
== Install
gem install libarchive
== Example
=== reading archive
require 'libarchive'
Archive.read_open_filename('foo.tar.gz') do |ar|
while entry = ar.next_header
name = entry.pathname
data = ar.read_data
#data = ""
#ar.read_data(1024) do |x|
# data << x
#end
puts "#name (size=#datadata.size)"
end
end
=== creating archive
require 'libarchive'
Archive.write_open_filename('foo.tar.bz2', Archive::COMPRESSION_BZIP2, Archive::FORMAT_TAR) do |ar|
Dir.glob('*.c').each do |fn|
ar.new_entry do |entry|
entry.copy_stat(fn)
entry.pathname = fn
ar.write_header(entry)
ar.write_data(open(fn) {|f| f.read })
#open(fn) do |f|
# ar.write_data do
# f.read(1024)
# end
#end
end
end
end
=== creating archive by extarnal program
require 'libarchive'
Archive.write_open_filename('foo.tar.lzo', 'lzop', Archive::FORMAT_TAR_USTAR) do |ar|
...
end
