Issue #19972 has been updated by vo.x (Vit Ondruch). Naming is hard obviously. When you mentioned that, `vendored_gems` immediately popped up on my mind, but there is already the `--vendor` option. Next I could think of was to shift the meaning a bit and rename `default_gems` => `std_lib` gems and `bundled_gems` => `default_gems`, which would have its own share of issues. Nevertheless, I am not that afraid of confusion with Bundler. ---------------------------------------- Feature #19972: Install default/bundled gems into dedicated directories https://bugs.ruby-lang.org/issues/19972#change-105401 * Author: vo.x (Vit Ondruch) * Status: Assigned * Priority: Normal * Assignee: hsbt (Hiroshi SHIBATA) ---------------------------------------- I think that the current situation, where the same directory (lets call it `Gem.default_dir`) is used for default/bundled gems as well as for user installed gems, is suboptimal. During the times, this has caused us quite some issue on Fedora. Historically, we redefined the `Gem.default_dir` to user home directory, to avoid the mixing of system gems and user installed gems. Unfortunately, with advent of default/bundled gems, we were facing issues that these gems were suddenly not listed, etc. I am realizing this issue in full once again since the "user install" RubyGems feature has landed [1]. I also think that we have arrived to this situation by evolution, not by design. Therefore my proposal is: Keep the `Gem.default_dir` for user `gem install`ed gems and lets install default and bundled gems into separate dedicated directories. Have separate `Gem.bundled_gems_dir` and `Gem.default_gems_dir` structures. Of course, if `Gem.default_dir == Gem.bundled_gems_dir == Gem.default_gems_dir`, we still can have the current layout. I have a simple POC here: https://github.com/ruby/ruby/pull/8761 BTW I have reported it here, because I think that RubyGems provides all it is needed. So it is not RubyGems ticket after all. However, I believe that RubyGems could benefit from this long term and some simplifications/cleanups would be possible.
