Issue #19337 has been updated by vo.x (Vit Ondruch). This is likely dupe of my #18381, which was not addressed yet. ---------------------------------------- Bug #19337: What is the difference between "default" gems and "bundled" gems? https://bugs.ruby-lang.org/issues/19337#change-101218 * Author: zzak (Zak Scott) * Status: Open * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Although I found [some answers](https://nts.strzibny.name/ruby-stdlib-default-bundled-gems/) on the [internet](https://stdgems.org), it seems like this information should be available from Ruby itself, if it's not already. Perhaps this is something we could add here? Open to other suggestions. https://github.com/ruby/ruby/blob/master/doc/standard_library.rdoc That blog pretty much answers the questions that I had fwiw. -- https://bugs.ruby-lang.org/
