On that note, I'm hesitant between writing my scripts in perl or python right now. Bash prevent sharing with Windows peoples... I just want to provide easy wrappers tools that are usually aroud 10 lines of shell, but testers ain't on linux so they cannot use them.
I don't know perl, but each time I interract with pyton's projects I have a different venv/poetry/... to setup. Forget adout it the next time and nothing is kept easy to reuse.
This is the issue for us, python outsiders. Each time we try we get a different answer with new tools. We are outside of the comtunity, we don't know the trend, old and new, pro and cons.
Your first recommandation is hatch... first time I've heard of it. Uv seems trendy in this thread, but before that it was unknown to me too.
As I understands it, it should be pip's job. When it detect I'm in a project it install packages in it and python use them. It can use any tool under the hood, but the default package manager shoud be able to do it on its own.
