From: matz@... Date: 2019-11-28T08:23:41+00:00 Subject: [ruby-core:96016] [Ruby master Feature#4539] Array#zip_with Issue #4539 has been updated by matz (Yukihiro Matsumoto). * The name `zip_with` is too confusing with `zip`. We need a new name. * The behavior can be described by the combination of `zip` and `map`. * I am not sure how much we need this behavior (yet). Matz. ---------------------------------------- Feature #4539: Array#zip_with https://bugs.ruby-lang.org/issues/4539#change-82857 * Author: citizen428 (Michael Kohl) * Status: Assigned * Priority: Normal * Assignee: matz (Yukihiro Matsumoto) * Target version: ---------------------------------------- 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/ Unsubscribe:
