A Ruby FFI binding to [libarchive][0].

This library provides Ruby FFI bindings to the well-known libarchive library.

Installation

Ensure that you have libarchive installed. On Debian/Ubuntu:

apt install libarchive13

On macOS with Homebrew:

brew install libarchive

Add this line to your application's Gemfile:

gem 'ffi-libarchive'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ffi-libarchive

Usage

To extract an archive into the current directory:

flags = Archive::EXTRACT_PERM
reader = Archive::Reader.open_filename('/path/to/archive.tgz')

reader.each_entry do |entry|
  reader.extract(entry, flags.to_i)
end
reader.close

To create a gzipped tar archive:

Archive.write_open_filename('my.tgz', Archive::COMPRESSION_GZIP, Archive::FORMAT_TAR_PAX_RESTRICTED) do |tar|
  content = File.read 'some_path'
  size = content.size
  tar.new_entry do |e|
    e.pathname = 'some_path'
    e.size = size
    e.filetype = Archive::Entry::FILE
    tar.write_header e
    tar.write_data content
  end
end
