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. set the priority of the async pool to high.

async.priority(50, 500)

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

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

4. run throught each element in a table.

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

5. async do while loop.

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

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

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

7. 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})

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

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

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

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