@ -10,38 +10,42 @@ Usage Async
```lua
async = async.Async()
```
2. set the priority of the async pool to high.
2. max time for thread before yielding (maxtime is in milliseconds).
```lua
async.priority(50, 500)
async.maxtime = 200
```
3. iterate from 1 to 50 and log the value i.
3. queue_threads is the amount of active threads when you run function queue_task.
```lua
async.queue_threads = 8
```
4. iterate from 1 to 50 and log the value i.
```lua
async.iterate(1, 50, function(i)
minetest.log(i)
end)
end, function() minetest.log("Callback") end)
```
4. run throught each element in a table.
5. run throught each element in a table.
```lua
local array = {"start", "text2", "text3", "text4", "text5", "end"}
async.foreach(array, function(k,v)
async.foreach(array, function(k, v)
minetest.log(v)
end)
end, function() minetest.log("Callback") end)
```
5. async do while loop.
6. async do while loop.
```lua
local c = 50
async.do_while(function() return c>0 end, function()
async.do_while(function() return c > 0 end, function()
minetest.log(c)
c = c - 1
end)
end, function() minetest.log("Callback") end)
```
6. register a async globalstep. this one spams the chat with the word spam.
7. register a async globalstep. this one spams the chat with the word spam.
```lua
async.register_globalstep(function(dtime)
minetest.chat_send_all("spam")
end)
```
7. chain task runs a group of functions from a table.
8. chain task runs a group of functions from a table.
```lua
async.chain_task({
function(args)
@ -53,17 +57,17 @@ async.chain_task({
args.count = args.count + 1
minetest.log(args.count)
return args
end})
end}, function(args) minetest.log(args.count) end)
```
8. adds a single function to the task queue. This is a sort of waiting list.
9. adds a single function to the task queue. This is a sort of waiting list.
```lua
async.queue_task(function()
minetest.log("Hello World!")
end)
end, function(args) minetest.log("callback") end)
```
9. Same as queue_task but the task does not go into a queue.
10. Same as queue_task but the task does not go into a queue.
```lua
async.single_task(function()
minetest.log("Hello World!")
end)
end, function(args) minetest.log("callback") end)
```
