3.12.0: sphinx warnings `reference target not found`

[kloczek]

First of all currently it is not possible to use straight sphinx-build command to build documentation out of source tree only

+ /usr/bin/sphinx-build -n -T -b man docs build/sphinx/man
Running Sphinx v6.2.1

Traceback (most recent call last):

    import pypdf as py_pkg
ModuleNotFoundError: No module named 'pypdf'

The above exception was the direct cause of the following exception:

Configuration error:

This can be fixed by patch like below:

Than .. on building my packages I'm using sphinx-build command with -n switch which shows warmings about missing references. These are not critical issues.

Here is the output with warnings:

I would merge a PR with the patch from above :-)

[MartinThoma]

About the warnings: I would need to look into that ... it's a bit weird that this doesn't / didn't have an effect. Or did I miss something?

[kloczek]

Those warnings are affecting .html, .pdf and .qch outputs by only peruce higlists without links in rendered documents.
Nevertheless this could be classified ad non-critical/low priority issue 😋
I'm only interested roff output (man page) however usually on packaging I'm trying to provide full feedback of all found issues.

[stefan6419846]

Most of these warnings are about the pypdf.generic submodule which we do not provide any API documentation for - probably because most users do not have to deal with this stuff. Some warnings are about the pypdf._encryption and pypdf.errors modules as well, which shares the similar reason. I am not sure what the best solution would be in this case.

Skimming through, I could observe some real issues, for example:

/home/tkloczko/rpmbuild/BUILD/pypdf-3.12.0/pypdf/_reader.py:docstring of pypdf.PdfReader.pages:1: WARNING: py:class reference target not found: pypdf._page.Page

Here the reference inside the text seems to be wrong as it points to Page instead of PageObject: https://pypdf.readthedocs.io/en/latest/modules/PdfReader.html#pypdf.PdfReader.pages

pypdf/pypdf/_reader.py
