Ruby FFI binding to libarchive

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

NOTE This gem is refactored / optimized version of ffi-libarchive with more tests to cover almost use-cases.

Ensure that you have libarchive installed.

• On Debian/Ubuntu:

  $ apt install libarchive13
  

• On macOS with Homebrew:

  $ brew install libarchive
  

• On Windows with msys2:

  $ pacman -S mingw-w64-x86_64-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

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)
end
reader.close

To create a tar-gzipped 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

After checking out the repo, run bundle install to install dependencies. Then, run bundle exec rake to run the tests. You can also run irb -r bundler/setup -r ffi_libarchive for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.
