⚠️ This project is still work in progress, and not published as a gem yet.

This is a Fiber Schduler, which is a missing piece to do concurrent programming in Ruby language.
If you are not familiar with the concept of Fiber Schduler, please refer to my presentation: Ruby の FiberScheduler を布教したい. (Sorry in Japanese.)

Add this line to your application's Gemfile:

gem 'async_scheduler'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install async_scheduler

Set this scheduler in the current thread. Then, surround each of blocking oerations in Fiber.schedule block so that they are executed concurrently.

Fiber.set_schduler AsyncScheduler::Scheduler.new

Fiber.schedule do
  File.read("file1.txt") # some blocking operation
end

Fiber.schedule do
  File.read("file2.txt") # some blocking operation
end

puts "Finished"

Add and run spec.

bundle exec rspec
