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. ``` Hi! Concurrent I/O seems like it is becoming more of a core consideration for languages these days, similar to how parallel processing has become increasingly important to get right. I felt like Ractors gave a good path away from Threads for parallel processing but there isn't a clear alternative for concurrency. It seemed nice for Ruby to also ship with a concurrent I/O library if a preferred one can be adopted. I do totally understand and agree that adding a gem to stdlib requires a high bar and exceptional circumstance. Repeated questions from Rubyists in the community about whether Ruby 3 has concurrent I/O just made me wonder if Async is worth promoting to the forefront. ---------------------------------------- Feature #18004: Add Async to the stdlib https://bugs.ruby-lang.org/issues/18004#change-92619 * 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.
