sualw

A small CLI tool that silences a process, gives you back your terminal, and lets you view the logs later on demand.

Installation:

If you are interested, since it hasn’t been published on PyPI yet, you can install it like this:

pip install git+https://github.com/EmmanuelNiyonshuti/sualw.git

Try it out:

$ sualw uvicorn main:app --reload

Ok.  uvicorn is running quietly  (pid 11292)
   log     ->  /home/emmanuel/.sualw/logs/uvicorn.log
   watch   ->  sualw toggle uvicorn
   stop    ->  sualw stop uvicorn
$ 

List all running processes with:

$ sualw list

 NAME      PID     STATUS    UPTIME   COMMAND                                      
───────────────────────────────────────────────────────────────────────────────────
 uvicorn   11292   running   -7035s   /home/emmanuel/works/sualw/.venv/bin/uvicorn 
                                      main:app --reload
$

Get back the logs with:

$ sualw toggle uvicorn

⟳  uvicorn  (live) - Ctrl+C to detach

stop the process with:

$ sualw stop uvicorn

✓  uvicorn received SIGTERM.

It was built out of my need to suppress webserver logs during development and get them back when I need them.There are other tools that can do similar things, but they felt a bit overkill for my simple use case, or maybe I just didn’t explore them well enough.

sualw will save these logs in the home directory under ~/.sualw/logs/{process_name}.log file, keep a json file registry for all processes in ~/.sualw/registry.json.

you can name the process anything you want, it must come before the -- separator right after sualw command, It will not be the name you name your process for example if you run some process that accepts a name and you pass it afterwars sualw myprocess --myprocess_name it will not be named myprocess_name but myprocess.
