async

async mod is a library pack. It adds two new node events and contains async functions.

Usage Async

1. create a async instance.

async = async.Async()

2. max time for thread before yielding (maxtime is in milliseconds).

async.maxtime = 200

3. queue_threads is the amount of active threads when you run function queue_task.

async.queue_threads = 8

4. iterate from 1 to 50 and log the value i.

async.iterate(1, 50, function(i)
	minetest.log(i)
end, function() minetest.log("Callback") end)

5. run throught each element in a table.

local array = {"start", "text2", "text3", "text4", "text5", "end"}
async.foreach(pairs(array), function(k, v)
	minetest.log(v)
end, function() minetest.log("Callback") end)

6. async do while loop.

local c = 50
async.do_while(function() return c > 0 end, function()
	minetest.log(c)
	c = c - 1
end, function() minetest.log("Callback") end)

7. register a async globalstep. this one spams the chat with the word spam.

async.register_globalstep(function(dtime) 
	minetest.chat_send_all("spam")
end)

8. chain task runs a group of functions from a table.

async.chain_task({
	function(args)
		args.count = 1
		minetest.log(args.count)
		return args
	end,
	function(args)
		args.count = args.count + 1
		minetest.log(args.count)
		return args
end}, function(args) minetest.log(args.count) end)

9. adds a single function to the task queue. This is a sort of waiting list.

async.queue_task(function() 
	minetest.log("Hello World!")
end, function(args) minetest.log("callback") end)

10. Same as queue_task but the task does not go into a queue.

async.single_task(function() 
	minetest.log("Hello World!")
end, function(args) minetest.log("callback") end)
