Or implement Promises plus await/async in Ruby maybe? The async and await combo especially is very powerful at simplifying asynchronous code. They are more than just a syntactic sugar. ---------------------------------------- Feature #18004: Add Async to the stdlib https://bugs.ruby-lang.org/issues/18004#change-92620 * 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.
