If you can provide a more detailed situation, it would be better. My situation is the same as Rafael's, and I fixed my code using the safe navigation operator: https://github.com/shugo/textbringer/commit/c859d13 Code like `/regex/ =~ str` has often been used when `str` may be `nil`, and such code has been rewritten using Regexp#match? after Ruby 2.4. This change will break all such code. ---------------------------------------- Feature #13083: {String|Symbol}#match{?} with nil returns falsy as Regexp#match{?} since ruby 3.0 https://bugs.ruby-lang.org/issues/13083#change-82444 * Author: kachick (Kenichi Kamiya) * Status: Closed * Priority: Normal * Assignee: * Target version: ---------------------------------------- Just for consistency * patch: https://github.com/ruby/ruby/pull/1506 * spec: https://github.com/ruby/spec/pull/380 Currently behaves as ( ruby --version: ruby 2.5.0dev (2016-12-28 trunk 57228) [x86_64-darwin16] ) ~~~ ruby 'string'.__send__(:=~, nil) #=> nil 'string'.match(nil) #=> TypeError: wrong argument type nil (expected Regexp) 'string'.match?(nil) #=> TypeError: wrong argument type nil (expected Regexp) :symbol.__send__(:=~, nil) #=> nil :symbol.match(nil) #=> TypeError: wrong argument type nil (expected Regexp) :symbol.match?(nil) #=> TypeError: wrong argument type nil (expected Regexp) /regex/.__send__(:=~, nil) #=> nil /regex/.match(nil) #=> nil /regex/.match?(nil) #=> false ~~~ Expected to ~~~ruby 'string'.__send__(:=~, nil) #=> nil 'string'.match(nil) #=> nil 'string'.match?(nil) #=> false :symbol.__send__(:=~, nil) #=> nil :symbol.match(nil) #=> nil :symbol.match?(nil) #=> false /regex/.__send__(:=~, nil) #=> nil /regex/.match(nil) #=> nil /regex/.match?(nil) #=> false ~~~ -- https://bugs.ruby-lang.org/ Unsubscribe:
