module: [kind=event] task_complete see: commands.execAsync To run a command which fires a task_complete event.

The @{task_complete} event is fired when an asynchronous task completes. This is usually handled inside the function call that queued the task; however, functions such as @{commands.execAsync} return immediately so the user can wait for completion.

Return Values

  1. @{string}: The event name.
  2. @{number}: The ID of the task that completed.
  3. @{boolean}: Whether the command succeeded.
  4. @{string}: If the command failed, an error message explaining the failure. (This is not present if the command succeeded.)
  5. : Any parameters returned from the command.

Example

Prints the results of an asynchronous command:

local taskID = commands.execAsync("say Hello")
local event
repeat
    event = {os.pullEvent("task_complete")}
until event[2] == taskID
if event[3] == true then
  print("Task " .. event[2] .. " succeeded:", table.unpack(event, 4))
else
  print("Task " .. event[2] .. " failed: " .. event[4])
end
