Hello everybody, I’m creating an app service aggregator, I created some modules, my idea it’s one module create tasks and inside other module create the await and select only one task, after you select one task you will be get a mutex, but this is another history. So I’m using this modules, one is “App” and another is “Driver”, when you add the name of app, It goes to create some Task async, the names that I’m gonna use, are created by a random name creation line. Until now it’s working well, the issue comes, when I try to execute the async from another module, says that I’m sending two arguments, I modified the function to get two params but not works, how can I get this async from other modules ? =D thanks my friends
defmodule Tarea2 do
defmodule App do
@app Apps
#### Start agent
def start do
Agent.start_link(fn -> %{} end, name: @app)
end
#### Start tasks from app
def task(app) do
for x <- 0..4 do
name = Enum.take_random(alphabet = Enum.to_list(?a..?e), 5)
:timer.sleep(1000)
name = Task.async(fn ->
pid = self()
ms = Enum.random(1..1000)
info = "Codigo #{name} : Hernan Cuy, lugar x lugar y, 20000"
Agent.update(@app, fn state -> Map.put(state, x, info) end)
:timer.sleep(120000)
IO.puts "#{inspect(pid)} finished in #{ms}ms"
Agent.update(@app, fn state -> Map.delete(state, x) end)
end)
end
end
#### getNotifications
def getNotifications do
Agent.get(@app, fn state -> Map.values(state) end)
end
def taskReceiver(name) do
Task.await(name)
end
end
defmodule Central do
@name __MODULE__
#### Start the principal agent
def start do
Agent.start_link(fn -> {} end, name: @name)
end
#### Add apps and start tasks
def aggregator(app) do
Agent.update(@name, fn state ->
Tuple.append(state, app)
end)
Tarea2.App.task(app)
end
#### Get all apps
def getApps do
Agent.get(@name, fn state -> state end )
end
end
defmodule Driver do
@mut MutexRegion
defstruct [name: "John", matricula: 28]
def aggregator(app) do
Tarea2.Central.start
Tarea2.App.start
Tarea2.Central.aggregator(app)
end
def taskReceiver do
msg = Tarea2.App.getNotifications
end
def selectTask do
taskSelected = String.trim(IO.gets("Ingrese codigo de solicitud a atender: "))
Tarea2.App.taskReceiver(taskSelected)
#Mutex.await(@defstruct, mutex2_id)
#Process.sleep(1000)
#Mutex.release(@defstruct, mutex1_id)
end
end
end
Here the error
iex(4)> Tarea2.Dirver.selectTask
