Status changed from Open to Closed Target version set to 2.5 Thank you Matz D.E. Akers: thanks for the patch! I adapted it for better handling of enumerables yielding multiple arguments, and also changing Hash#any? / Array#any? which have their own versions. Merged. ---------------------------------------- Feature #11286: [PATCH] Add case equality arity to Enumerable's sequence predicates. https://bugs.ruby-lang.org/issues/11286#change-68254 * Author: 0x0dea (D.E. Akers) * Status: Closed * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: 2.5 ---------------------------------------- ## Proposal It is proposed that `Enumerable`'s sequence predicates (`#all?`, `#any?`, `#none?`, and `#one?`) be augmented to return, in the case of a single argument, whether their query holds when each element is supplied to the argument's `#===` method. ## Rationale `Enumerable#grep` filters by case equality, allowing us to write very natural and expressive code: ```ruby strs.select { |str| /foo/ === str } strs.grep(/foo/) nums.select { |num| (5..10) === num } nums.grep(5..10) ``` In addition to taking advantage of the versatility of case equality, it lets us do away with the syntactic noise incurred by opening a block. `#grep` is a very nice method! Let's make `#all?` and friends more like `#grep`. ---Files-------------------------------- 0001-enum.c-add-case-equality-arity-to-sequence-predicates.patch (10 KB) case_equality_sequence_predicates-check_argc_before_deref.patch (10 KB) case_equality_sequence_predicates-all_updates.patch (9.94 KB) -- https://bugs.ruby-lang.org/
