Issue #21766 has been updated by Dan0042 (Daniel DeLorme). Remember that `FileUtils` is loaded dynamically, so it would be something like ```ruby class Pathname def mkdir_p(...) = _fileutils(:mkdir_p, ...) def ln(...) = _fileutils(:ln, ...) def ln_s(...) = _fileutils(:ln_s, ...) def ln_sf(...) = _fileutils(:ln_sf, ...) def cp(...) = _fileutils(:cp, ...) def cp_r(...) = _fileutils(:cp_r, ...) def mv(...) = _fileutils(:mv, ...) def rm(...) = _fileutils(:rm, ...) def rm_r(...) = _fileutils(:rm_r, ...) def rm_rf(...) = _fileutils(:rm_rf, ...) private def _fileutils(name, ...) require "pathname/fileutils" send(name, ...) end end #pathname/fileutils.rb require "fileutils" class Pathname def mkdir_p(...) = FileUtils.mkdir_p(@path, ...) def ln(...) = FileUtils.ln(@path, ...) def ln_s(...) = FileUtils.ln_s(@path, ...) def ln_sf(...) = FileUtils.ln_sf(@path, ...) def cp(...) = FileUtils.cp(@path, ...) def cp_r(...) = FileUtils.cp_r(@path, ...) def mv(...) = FileUtils.mv(@path, ...) def rm(...) = FileUtils.rm(@path, ...) def rm_r(...) = FileUtils.rm_r(@path, ...) def rm_rf(...) = FileUtils.rm_rf(@path, ...) end ``` ---------------------------------------- Feature #21766: Pathname + FileUtils making sweet music together https://bugs.ruby-lang.org/issues/21766#change-115479 * Author: gurgeous (Adam Doppelt) * Status: Open ---------------------------------------- I love Pathname. I love FileUtils. Let's bring these two classes EVEN CLOSER TOGETHER by adding some tragically missing helpers. Something like this, perhaps? ``` ruby class Pathname def mkdir_p(...) = FileUtils.mkdir_p(@path, ...) def ln(...) = FileUtils.ln(@path, ...) def ln_s(...) = FileUtils.ln_s(@path, ...) def ln_sf(...) = FileUtils.ln_sf(@path, ...) def cp(...) = FileUtils.cp(@path, ...) def cp_r(...) = FileUtils.cp_r(@path, ...) def mv(...) = FileUtils.mv(@path, ...) def rm(...) = FileUtils.rm(@path, ...) def rm_r(...) = FileUtils.rm_r(@path, ...) def rm_rf(...) = FileUtils.rm_rf(@path, ...) end ``` There are some concerns about making pathname.rb more dependent on FileUtils, which I understand. What's the best way forward? Let's do it! (also see https://github.com/ruby/pathname/issues/64 and https://github.com/ruby/pathname/issues/72) -- https://bugs.ruby-lang.org/
