ltask is inspired by skynet (https://github.com/cloudwu/skynet) , but it's a library rather than a framework.
It implement an n:m scheduler , so that you can run M lua VMs on N OS threads.
Each lua service (an indepentent lua VM) works in request/response mode, they use message channels to inter-communicate.
root is a special service that can spawn new services. For example,
-- user
local ltask = require "ltask"
local S = {}
print "User Start"
function S.ping(...)
ltask.timeout(10, function() print(1) end)
ltask.timeout(20, function() print(2) end)
ltask.timeout(30, function() print(3) end)
ltask.sleep(40) -- sleep 0.4 sec
-- response
return "PING", ...
end
return S-- root
local function boot()
print "Root Start"
print(os.date("%c", (ltask.now())))
local addr = S.spawn("user", "Hello") -- spawn a new service `user`
print(ltask.call(addr, "ping", "PONG")) -- request "ping" message
end
