From: "matheusrich (Matheus Richard) via ruby-core" Date: 2025-05-16T20:47:27+00:00 Subject: [ruby-core:122156] [Ruby Feature#4539] Array#zip_with Issue #4539 has been updated by matheusrich (Matheus Richard). @matz maybe too obvious, but how about `zip_map`? ---------------------------------------- Feature #4539: Array#zip_with https://bugs.ruby-lang.org/issues/4539#change-113305 * Author: citizen428 (Michael Kohl) * Status: Assigned * Assignee: matz (Yukihiro Matsumoto) ---------------------------------------- Inspired by Haskell's `zipWith` function, I hacked on together for Ruby: ```ruby [1,2,3].zip_with([6,5,4], :+) #=> [7, 7, 7] [1,2,3].zip_with([6,5,4]) { |a,b| 3*a+2*b } #=> [15, 16, 17] ``` So far I only have a Ruby version of it: https://gist.github.com/731702b90757e21cadcb My questions: 1. Would this method be considered a worthwhile addition to `Array`? 2. I've never hacked on the C side of Ruby (read some parts of the source though) and my C is quite rusty. I'd like to change that, would somebody be willing to help me turn this into a proper patch? -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/lists/ruby-core.ml.ruby-lang.org/
