Issue #19985 has been updated by zverok (Victor Shepelev). Actually, it seems kinda weird that Pathname doesn't have implicit conversion to a String (`#to_str`). OTOH, [Pathname#to_path](https://docs.ruby-lang.org/en/3.2/Pathname.html#method-i-to_path) docs seem to claim that having `#to_path` is an agreement to represent "path-like" things, which, say `File.open` respects, but bare `require` ignores. Rubygems [respect the agreement](https://github.com/rubygems/rubygems/blob/master/lib/rubygems/core_ext/kerne...) through calling [File.path](https://docs.ruby-lang.org/en/3.2/File.html#method-c-path). The funny thing though is there is no method where the agreement is documented! Even `File.path` which implements it never documents how exactly it evaluates "string representation of the path" :) ---------------------------------------- Feature #19985: Support `Pathname` for `require` https://bugs.ruby-lang.org/issues/19985#change-105144 * Author: vo.x (Vit Ondruch) * Status: Open * Priority: Normal ---------------------------------------- It seems that RubyGems / Bundler `require` method overrides of accept `Pathname` as and argument ~~~ $ ruby -rpathname -e ' pa = Pathname.new("test") require pa ' <internal:/usr/share/rubygems/rubygems/core_ext/kernel_require.rb>:85:in `require': cannot load such file -- test (LoadError) from <internal:/usr/share/rubygems/rubygems/core_ext/kernel_require.rb>:85:in `require' from -e:3:in `<main>' ~~~ while plain Ruby require does not: ~~~ $ ruby --disable-gems -rpathname -e ' pa = Pathname.new("test") require pa ' -e:3:in `require': no implicit conversion of Pathname into String (TypeError) from -e:3:in `<main>' ~~~ This inconsistency is surprising. It seems that RubyGems / Bundler developers think [1] that Ruby `require` should also accept `Pathname`. ~~~ $ ruby -v ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-linux] ~~~ [1]: https://github.com/rubygems/rubygems/pull/7128 -- https://bugs.ruby-lang.org/
