Issue #21350 has been updated by Eregon (Benoit Daloze). In the meanwhile https://www.rubydoc.info/ is a good workaround to get online docs of all gems, e.g. https://www.rubydoc.info/gems/csv Though it doesn't handle RDoc includes yet it seems. ---------------------------------------- Misc #21350: Bundled gems lack online documentation https://bugs.ruby-lang.org/issues/21350#change-113348 * Author: osyoyu (Daisuke Aritomo) * Status: Open ---------------------------------------- Libraries which have been converted into bundled gems seem to have no online documentation. For example, `csv` had its documentation inside docs.ruby-lang.org up to Ruby 3.3: https://docs.ruby-lang.org/en/3.3/CSV.html but after it has turned into a bundled gem, there is no online documentation (try searching in https://docs.ruby-lang.org/en/3.4/). This is the case for all bundled gems, including major modules such as `Base64` (missing since 3.4 docs) and `Logger` (missing since master docs). Given that these libraries are still `require`able without any special installation, it would be nice to have their documentation on docs.ruby-lang.org (or somewhere online reachable from Google). -- https://bugs.ruby-lang.org/
