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
- [
string]: The event name. - [
number]: The ID of the task that completed. - [
boolean]: Whether the command succeeded. - [
string]: If the command failed, an error message explaining the failure. (This is not present if the command succeeded.) - …: 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
