A more convenient pdm run

Is your feature request related to a problem? Please describe.

I often find myself wanting to just fire up a Python interactive prompt using pdm's __pypackages__ in sys.path. I believe the way to do that is with pdm run python (at least, that works for me. But maybe we can be a little more convenient or discoverable. I admit this is a pretty minor convenience, so I don't mind if you close as Won't Fix.

Describe the solution you'd like

What if pdm run with no command were equivalent to running interactively the Python specified by pdm use? If you wanted to do anything more clever (e.g. pdm run python -c "whatever") you'd have to do that explicitly of course.

If you enabled PEP 582 in your shell, you can just run python -m some_package_installed_in_pypackages some args. Or python -c "import some_package; etc". Your interpreter will find the packages 🙂

You won't be able to directly call the scripts installed in __pypackages__/*/bin though. For this you still need to do pdm run some_package_script.

Yep. I just don't generally enable this in my shell.

Oh, OK 😊 Out of complete curiosity, why is that?

[warsaw]

A couple of reasons. My shell configs are a bit weird, having accumulated a lot of cruft over the decades. I also like to keep my shell environment tightly controlled. While I like the idea of PEP 582, I'm still a bit leery as to the security implications of it, especially with bin enabled. For now, I prefer to explicitly opt in when necessary.

I see, thanks!

I often find myself wanting to just fire up a Python interactive prompt using pdm's pypackages in sys.path.

How about source .venv/bin/activate?

The question was about __pypackages__, not venvs 🙂
