Async is an awesome gem that I basically support. But there are whole lot of other gems that are equally awesome. What do you think makes async gem so special among other gems that it would be worth being added into the core? These days you need a really decent reason to turn a gem into a standard library. ---------------------------------------- Feature #18004: Add Async to the stdlib https://bugs.ruby-lang.org/issues/18004#change-92618 * Author: shan (Shannon Skipper) * Status: Open * Priority: Normal ---------------------------------------- Adding Async to the stdlib would signal a clear concurrency story for Ruby 3 to compliment Ractor-based parallelism. I don't know how ioquatix feels about adding Async to stdlib, but I wanted to propose it since we keep getting questions about concurrent I/O with Ruby 3 in the community. Ractors get a fair amount of attention on the #ruby IRC channels and Ruby Discord. When Ractors are discussed, question around concurrent I/O in Ruby 3 often follow. Folk don't seem to be aware of Async, so we often cite the Ruby 3 release notes Async Net::HTTP example shown below. ``` ruby require 'async' require 'net/http' require 'uri' Async do ["ruby", "rails", "async"].each do |topic| Async do Net::HTTP.get(URI "https://www.google.com/search?q=#{topic}") end end end ``` The main downside I see for this proposal is the bloat from Async's several gem dependencies. For what it's worth, nio4r has been a staple for a long time and is also the only dependency of Puma. ``` Async is a composable asynchronous I/O framework for Ruby based on nio4r and timers. ``` Async is just so useful it would be awesome to add to the stdlib. It fills and important gap for concurrent I/O with Ruby 3 and would be exciting to see included in a future release.
