Issue #12533 has been updated by Artem Khramov. Description updated ---------------------------------------- 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-59421 * Author: Tiago Cardoso * Status: Open * Priority: Normal * Assignee: ---------------------------------------- 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 <main>': 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: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
