"All-in-one" archives library?

Ruby
1

Hi all.

I’d like to see some library which handles most popular archive types
(zip,
rar, tar, gz, bz2 …) in uniform way, just like rubyzip[1] does:

require ‘some-very-cool-library’

Dir[‘myarchive.zip’].each …

Or even

Dir[‘myarchive.zip/otherone.rar/evenother.bz2’].each …

Is something like this exists in the world?

Thanks.

Victor.

Can you drop me an email with what you’d really like to see? TRUG is
working on libarchive this weekend at a hackathon.

At the moment, there’s archive-tar-external, which basically wraps calls
to
installed software with popen. So, if you have all these tools
installed
already, you can do something like:

  require 'archive/tar_external'

  t = Archive::Tar::External.new( name )
  t.compressed_archive_name = name
  if name =~ /\.bz2/
    t.uncompress( "bunzip2" )
  elsif name =~ /\.gz/
    t.uncompress( "gunzip" )
  elsif name =~ /\.zip/
    t.uncompress( "unzip" )
  end
  if name =~ /\.t(ar\.)?(gz)?/
    t.extract
  end

HTH,
