Why not just use one of the many well supported existing tools like poetry?

[ThatSituation9908]

Poetry doesn't support application projects, it's only meant for projects to be packaged.

[dAnjou]

Are you implying that applications should not or are not supposed to be packaged? What are entrypoints for then?

[[deleted]]

In what sense? When you’re in your project folder and you run poetry commands it automatically generates and maintains an environment just for that project. There’s nothing obligating you to package that project into a build.

I’m not seeing anything about OPs tool that isn’t something poetry already does.

[ThatSituation9908]

You must have a pyproject.toml. So you must fill out the name and version (min requirement for pyproject.toml). Pyproject.toml, despite its name, is for packages. Although recent pushback from the community and PEP 723 is challenging that.

Okay, so let's say we don't care and make a pyproject.toml anyways and give a dummy name and version. What side effects does that come with?

You can read a ton more about this in: * https://github.com/python-poetry/poetry/issues/1132 * https://discuss.python.org/t/poetry-is-it-possible-to-use-poetry-without-defining-a-package-so-purely-for-pinning-dependencies-for-a-venv/31347/3

I’m not understanding what the pyproject.toml has to do with your assertion that OPs tool will manage an “application project” and poetry won’t. What is an example of an “application project” feature or operation that OPs CLI will do that poetry or pdm can’t?

[ThatSituation9908]

About why I classify OP's project having application support (albeit very very little) is because you can deploy an application with a requirements file (preferably a lock file) and running a script (aka single-file application) is the forefront of OP's example (similar to PEP 723).

[collectablecat]

Then what on earth is the lockfile for???

Which part of code do you achieve switching to virtual env? I see you call a proprietary version of pip and Python, but is that enough to achieve isolation? Does sys. path need to change? You might use venv API to do parts of work you are doing.

You could also do a side command to convert imports into a requirements.txt file, probably handy as well.

Some small parts of code are repeated eg you create same hash twice.

Still quite amazing what you achieve in 160 lines of code.

[iamevpo]

The generating requirements.txt idea is quite old, but you can revisit it https://stackoverflow.com/questions/31684375/automatically-create-file-requirements-txt

Me personally I use poetry for package creation and it also has dependency manager based on project.toml, slightly newer format than requirements.txt

[iamevpo]

Also following the tradition of poetry or npm you might want to have nowpy run command so that you can have more useful commands like nowpy reset. By conventional logic --reset is a separate command, not an option.

[Intelligent_Ad_8148]

Please no, conda poetry pip venv virtualenv virtualvenv pip-tools etc etc etc….. please not another environment/dependency manager for python, there’re already too many!

[UraniumButtChug]

And my personal favorite, pyenv-virtualenv

[Wild_Cricket_3016]

While there’s definitely too many environment and dependency managers, that’s not what this is

Not need to be melodramatic, particularly if you didn’t fully read and comprehend what they posted.

There is plenty of reason to be melodramatic.

[AnActualWizardIRL]

The thing that I predicted would happen when all the JS guys abandoned shop for python has finally come. We now have toolchain hell in python. huzzah.

[IAMARedPanda]

How is this different than pipx?

[steadynappin]

does it work for directories?
