watcher-cli 0.0.1

A watcher for running python code when after every modification

python-watcher

I've crated this project to watch over a repo dir and execute a file after modifying anything on that same dir. Its lightweight since it only has watchdog as a dependency.

Parameters for running

-d or --dir (required): 
    Folder you want the watcher to look for changes. Defaults to "."
-f or --file (required): 
    Script that you want to run after a file is changed (probably you main.py or something similar)
-t or --time (optional):
    Time delay to run again (good when saving constantly). Defaults to 1.
--test (optional):
    If the watcher should run a pytest command instead of python. Defaults to False.

To run

Watching and executing a python script:

watcher -d . -f watcher.py  

Watching and executing pytest

watcher --test

For dependencies all you need to do is run

pip install -e .

Use cases

Although trivial, there are some uses cases that made me create this package:

• Run pytest when saving a file.
• Run pylint when making corrections.
• Run smaller scripts after every modification.

Mostly I was tired off having to tab out from vim just to run pytest/pylint/python on the terminal.

Todo

• create a proper setup
• make it executable from command line
• be able to pass parameters
• read parameters from yaml file
• only watch a single file changes
• run pytest
• run pylint
  • to run pylint there has to be a folder to run pylint over
  • fail with some threshold
• Spawn a new process to close if needed (more control over running process)
• Create documentation
• Create tests
• Publish
• Fix pytest not working on GitHub actions
