update gnu_tar.rb removed tab update unpacking_strategy/tar.rb to resolve conversations But OFFENCE found, W: 31: 36: Unused method argument - basename (brew style) Now I start to using rubocop inside Sublime_text3 where I see all right linting messages. Rollback install.rb changes. Conversation resolved, extra_args: "--owner=0", "--group=0" and "--no-same-owner" in extend/os/linux/gnu_tar.rb. Conversation: file extend/os/linux/gnu_tar.rb moved to extend/os/linux/unpack_strategy/tar.rb. Module UnpackStrategy is parent for the GnuTar module. Conversation: new file extent/unpack_strategy/tar.rb to require logic, unpack_strategy/tar.rb newline bef. require-line, require-line changed. Deletion of files added in PR. -o addition is only one needed argument in unpack_strategy/tar.rb.
