[Masara]

Closes #80

Summary of Changes

Fixed the stub generator, it should now run with the Library project.

To run the script, use the following command:
safe-ds-stubgen -p "Library" -o "path/to/out" -nc -s "path/to/Library/src" --docstyle NUMPYDOC

[Masara]

@lars-reimann The src.safeds.data.tabular.containers._column.Column.all, src.safeds.data.tabular.containers._column.Column.any and src.safeds.data.tabular.containers._column.Column.none methods have Callable[[T], bool]) as type for the predicate parameter. The type is written wrong b/c of the ) at the end of the type.

@lars-reimann I removed the raises like you said and instead added the unknown type. I also removed the -p (package name) argument, since we don't really need it. Could you check again if it works for you?

[Masara]

@lars-reimann Could you also check the linter error?

@Masara You can replace the link with https://dsl.safeds.com/en/stable/stub-language/.

[Masara]

I added a # pragma: no cover for the function safeds_stubgen.api_analyzer._get_api._get_nearest_init_dirs since I don't know how to test it. The glob searches every file and is usually sorted the way we want, but we have to make sure anyway if it's the file we need, since we can't be 100% sure that glob always does what we want. But I can't write tests for test coverage, since the glob sorts the files for us.

[lars-reimann]

Works beautifully now, thank you.
