# A Command Queue for Python

Run commands (which can be regular functions) in a FIFO queue. Can be run in a background thread.

## Usage examples

Simple filling and running of the queue

```python

from command_queue import CommandQueue

from command_queue.commands import FunctionCommand

import functools

example_queue = CommandQueue()

# Add example commands

for i in range(100):

    example_queue.add_command(

        FunctionCommand(functools.partial(print, f"Running loop iteration {i}"))

    )

# Attempt to run command queue at 60 commands per second

# Stop running once queue empties

example_queue.spin(60, until_empty=True)

```

Example of ParallelCommandGroups

```python

from command_queue import CommandQueue

from command_queue.commands import FunctionCommand, ParallelCommandGroup

import functools

import time

def do_something():

    print(f"Something happended on {time.time()}")

    time.sleep(0.05)

def do_something_2():

    print(f"Something_2 happended on {time.time()}")

    time.sleep(0.05)

example_queue = CommandQueue()

# Add example non-parallel commands

# These commands will run sequentially

for i in range(2):

    example_queue.add_command(FunctionCommand(functools.partial(do_something)))

# These commands will run at the same time using threads

# Add example parallel command

# These commands will run at the same time

example_queue.add_command(

    ParallelCommandGroup(

        FunctionCommand(functools.partial(do_something_2)),

        FunctionCommand(functools.partial(do_something_2)),

        FunctionCommand(functools.partial(do_something_2)),

        FunctionCommand(functools.partial(do_something_2)),

        FunctionCommand(functools.partial(do_something_2)),

        FunctionCommand(functools.partial(do_something_2)),

    )

)

# Attempt to run command queue at 10 commands per second

# Stop running once queue empties

example_queue.spin(10, until_empty=True)

```
