Issue #20056 has been updated by zverok (Victor Shepelev). Status changed from Open to Closed
Dir#chdir implicitly calls Dir.chdir or Dir.fchdir with the passed block, so the block form does work, but it apparently is not documented:
Ugh, indeed. My bad. Instead of checking manually, just looked in the code and didn't saw anything related to block passing— but now I understand. I'll push a small docs adjustment in the evening into https://github.com/ruby/ruby/pull/9183 while fixing the review notes. ---------------------------------------- Misc #20056: Dir#chdir inconsistency with Dir.chdir https://bugs.ruby-lang.org/issues/20056#change-105619 * Author: zverok (Victor Shepelev) * Status: Closed * Priority: Normal * Assignee: jeremyevans0 (Jeremy Evans) ---------------------------------------- I am not sure it is important; I just wanted to understand if this is intentional or accidental. 1. There is no block form for `Dir#chdir`, unlike `Dir.chdir` (the form that will return to the previous directory when the block is finished) 2. `Dir.chdir` returns `0`, while `Dir#chdir` returns `nil` (both seem to be not representing any particular internal value, just a hardcoded return value). -- https://bugs.ruby-lang.org/
