Threaded Task Executor

Allows functions to be called in a seperate thread and executed in FIFO order.

Possible Uses:

• For serial communication where send/recv order matters
• Run background tasks in tkinter easily, without freezing gui
• Any application where background tasks are required to be executed in order

Gettings Started:

Installing

pip install threaded-task-executor

Importing

from threaded_task_executor import Task_Queue, Task

How To Use

tasks = Task_Queue()
tasks.add_task(Task(print, args=("test 1")))
tasks.add_task(Task(print, args=("test 2")))

When this is run it should start the thread and execute the tasks in FIFO order.

Documentation:

Task(func, callback=None, task_name="", args=(), kwargs={})

• func : the function that will be called when executed
• callback : function that will be run when the task has started and finished
  • callback("STARTED", task_name)
  • callback("FINISHED", task_name)
• task_name : the name of the task
• args : tuple of arguments that will be given to the function
• kwargs : dict of keyword arguments that will be given to the function

Task_Queue(daemon=None)

• daemon : (True, False, None) : Whether main thread has to wait for thread to finish before stopping main thread
• add_task(new_task) : Adds a new task obj, if there is no threads running will start one
• get_current_task() : Allows for the current task that is executing to be returned
• tasks_left() : Returns the number of tasks left to be completed, includes currently executing task if any.
• add_from_func(callback, task_name) : used as a decorator which acts as add_task()

Updates:

1.1

• New decorator method that allows for adding to a Task_Queue obj
