Re: No stubs for python-lxml

Well your output makes no sense. Where did it come from? What's the actual issue?

Even that last line doesn't seem to be from pacman.

Re: No stubs for python-lxml

python-lxml it's obviously Python library, it's pretty easy to distinguish by "python-*" pattern you know..

so problem shows up in Python with Pylance (in VSCode in my example, but it's doesn't matter)

Re: No stubs for python-lxml

So no real information to add.

python-lxml is fine.

% python
Python 3.10.4 (main, Mar 23 2022, 23:05:40) [GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import lxml.html
>>> quit()

I guess I just don't know what python output looks like? Or don't know what pacman output looks like? Sure, then, good luck.

Re: No stubs for python-lxml

with Pylance

The python code works fine, but it looks like pylance tries to use static type information for some code verification or so. That requires an additional package for lxml, since the lxml metadata is not part of the typeshed package anymore.

Finally! Someone that have some understanding..

so, since the typing is a thing now (almost a whole 3.10 update was related to Typing module)  ->  would be nicer to ship these packages together

Re: No stubs for python-lxml

pylance doesn't appear to be present in archlinux repos, are there other programs that need this information that are ?

Re: No stubs for python-lxml

mypy appears to be used for testing code by multiple other tools.

If there is proof/examples/usecases that those tests would benefit from archlinux having lxml-stubs in repos, a feature request to add lxml-stubs might have a chance to get accepted.

If the benefit is hard to proof (or the request is denied) , an aur package could be an alternative.

w/o stubs - you have no type hinting, errors all over the code, it's so bad so you have to change python language server from pylance(pyright) to jedi

Re: No stubs for python-lxml

That shows pylance benefits from stub files, but pylance is not in archlinux repositories .

To have any chance for python stub packages in archlinux repos there needs to be a clear advantage for archlinux that offsets the work needed to add them.
