Streamlit Process Manager

Let's be honest, trying to manage external processes or subprocesses from a Streamlit app is tricky. The execution model makes it difficult to keep track of which processes are supposed to be running and which ones aren't. Half the time you end up spawning twenty different processes all trying to access the same file and stomping all over one another.
Streamlit Process Manager attempts to make a that a bit easier. It looks something like this:
import streamlit_process_manager as spm

# Get the global ProcessManager
pm = spm.get_manager()

# Configure the Process and start it
my_program = ["python", "my_program.py"]
output_file = "program_output.txt"
process = pm.single(spm.Process(my_program, output_file))
process.start_safe()

# Run the process and monitor it in streamlit!
spm.st_process_monitor(process).loop_until_finished()

⚠️ DISCLAIMER ⚠️
Runing processes on your machine from a public-facing
application like a Streamlit app can be incredibly risky and comes
with all sorts of security considerations. Use this project on public apps
at your own risk, and never inject user-provided values or arguments
into your processes without serious consideration of all the possible injection
attacks you might be opening your server up to.

Installation
pip install streamlit-process-monitor
Requires

Python 3.8.* or above
Streamlit 1.30.* or above
psutil 5.9.8 or above

Development
This project uses pdm for most of its development tooling. Ensure you have python3.8 installed, then run
pip install pdm
pdm venv create 3.8
pdm install --dev --group test --group lint

to get started, then run
pdm check

to verify that everything is set up and ready to go.

If you must use Python 3.12 or greater, you may have issues with numpy 1.24 needing to be
built from source since it only supports python versions up to 3.11.

Testing with tox
If you have multiple versions of Python available on your system you can use tox to run tests
on all of them at once. tox should be installed when you install the --dev dependencies so
you can just run it. Any Python's not available on your system will be skipped.
pdm run tox
