The VSCode extension `djlint` should not require people to install the Python package

[nbro]

Under the hood, the VSCode extension djlint should take care of installing djlint with pip or whatever in an isolated environment, which should be removed whenever we remove the extension. I shouldn't need to add this dependency to my pyproject.toml (with poetry) just to make the VSCode extension work.

You can use pipx

[nbro]

My point is that I shouldn't need to use any Python package manager (pip, pipx, pip-tools, poetry, whatever) to make the VSCode extension work. We should just need maybe Python and that's it. So, the Python package should be installed automatically, in some virtual environment, whenever we install the VSCode extension, and it should be removed automatically, along with the virtual environment, whenever we remove the extension

What if I have a global djlint installed (/opt/homebrew/bin/djlint, for example)?

The current behavior is to tell me to install djlint in the current venv.

I agree this extension should not require people to manually install a Python package. Other extensions like Prettier and ESLint bundle their requirements as a fallback but allow you to use your own version if you want. I have gone to some lengths to ensure that I can work on my project both inside a dev container (where my application packages, which don't include djlint) are installed AND outside a dev container, where NO python packages are installed. I never actually run the project outside of a dev container, so I have no need to manage system Python and venvs etc.

[monosans]

Contributions are welcome. We can use pyodide and call Djlint's python api directly, as on djlint.com website.

[mrmachine]

If I understand correctly, that would avoid even needing python installed on the host OS and would run djlint directly inside a vscode managed browser process?

And there's a working example of running djlint in this manner on the djlint.com website?

Sounds great.

The readme does not directly address this. I do not use python but I want the extension for its twig formatting. I have djlint installed via homebrew. Please explain and update the readme on how to use it.

I can't get the extension to work either. I installed djlint in my workspace's venv and I have a user installation as well. "Use Venv" is enabled in the settings and I have set the Python path to the venv's interpreter. I also tried disabling "Use Venv", to see if the specified Python interpreter would be used. Nothing works.

The output is always the same:

}

It's installed though:

jonas@linux:~$ /bin/python -m pip install djlint -q
jonas@linux:~$ /bin/python -iq
>>> import djlint
>>> 
jonas@linux:~$ /bin/python -m djlint
Usage: python -m djlint [OPTIONS] SRC ...
Try 'python -m djlint -h' for help.

Error: Missing argument 'SRC ...'.

Any help would be appreciated!

@kitsguru @ungive please try new extension version.

[kvnwaks]

I hope this would be implemented soon - an extension with a bundled-up djlint package. It would be highly appreciated.
