This is simple task library, that let you use more than one thread.
To install this library, you have to copy/symlink src/task.lua to your luarocks package folder.
For example, installing this library globally on Linux:
git clone https://github.com/VALAD47/task.git
cd task
sudo cp src/task.lua /usr/share/lua/5.4/
First of all, you have to require this library:
local task = require("task")
Next step, you should wrap all your code into function, and then use task.spawn(f), where f is function with your code.
At the end of your code, you must run task.loop() function, in order to all tasks work. Keep in mind, that this function creates infinity loop, that will only wnd when all tasks are done. If you want to this loop never end, simply change task.CLOSE_WHEN_NO_JOBS to true. If you want to integrate these loop into your own cycle, use function task.step() in your loop.
If you want to hold your function execution for t time, use task.wait(t).
If you want to create infinity loop, that will not suspend other tasks execution, simply write this:
while task.wait() do
-- Your code --
end
It may a little slow down count of code repeating in second, but other your tasks will continue their work without troubles.
Keep in mind, that you have to call task.wait() in your wrapped functions, in order to other wrapped functions do their jobs in "multi-thread".
