From: "jeremyevans0 (Jeremy Evans)" Date: 2021-10-27T16:52:37+00:00 Subject: [ruby-core:105830] [Ruby master Feature#12533] Refinements: allow modules inclusion, in which the module can call internal methods which it defines. Issue #12533 has been updated by jeremyevans0 (Jeremy Evans). Status changed from Assigned to Closed `Refinement#include` has been deprecated. `Refinement#import_methods` can now be used to handle this use case: ```ruby module Extensions def vegetables ; potatoe ; end def potatoe ; "potatoe" ; end end module Refinary refine String do import_methods Extensions end end using Refinary p ''.vegetables # => "potatoe" ``` ---------------------------------------- Feature #12533: Refinements: allow modules inclusion, in which the module can call internal methods which it defines. https://bugs.ruby-lang.org/issues/12533#change-94361 * Author: chucke (Tiago Cardoso) * Status: Closed * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Right now this isn't possible: ~~~ruby module Extensions def vegetables ; potatoe ; end def potatoe ; "potatoe" ; end end module Refinary refine String do # this doesn't work include Extensions # this would work... # def vegetables ; potatoe ; end # def potatoe ; "potatoe" ; end end end using Refinary puts "tomatoe".vegetables #=> in
': undefined method 'vegetables' for "tomatoe":String ~~~ Wrongly reported as a bug [here](https://bugs.ruby-lang.org/issues/12514). According to Shugo Maeda, this was expected behaviour. I argued that this is the way most monkey-patches work, and if Refinements can't cover the use case of inserting a custom DSL which references itself in the classes it refines, it can't fully replace monkey-patches, which I read was the main reason Refinements have been added to the language. -- https://bugs.ruby-lang.org/ Unsubscribe:
