jellopy - Ruby async/await syntax

gem install jellopy

Inspired by Python 3.5 (PEP-0492)

Note that await has to be used only in functions with the async keyword.

require 'jellopy'

$eloop = EventLoop.new

async def test1
  puts 'test1 before sleep'
  asleep 10
  puts 'test1 after sleep'
end

async def test3
  puts 'test3 before sleep'
  asleep 2
  puts 'test3 after sleep'
end

async def test2
  puts 'test2 before await'
  await(test1)
  puts 'test2 after await'
end


$eloop.create_task(test2)
$eloop.create_task(test3)
$eloop.start

Output:

test2 before await
test3 before sleep
test1 before sleep
test3 after sleep
test1 after sleep
test2 after await
