Unintentionally, uninitialized attributes defined at superclasses are
recognized as undocumented in the filtering step. Therefore, they are
filtered if `:undoc-members:` option given.
Deprecate `no_docstring` argument for `Documenter.add_content()` again.
At the first trial (#8533), it changes the behavior of
`autodoc-process-docstring` event; it is emitted unexpectedly for an
alias of class. But it brings an incompatible change to extensions.
Hence it was partially reverted at #8581.
This keeps not calling the event for an alias of class. To do that,
now `Documenter.get_doc()` can return None value.
To support instance attributes on super class, get_class_members() scans
the instance attributes defined at super classes using ModuleAnalyzer.
It allows to generate document for them when users gives :
inherited-members: option.
To avoid filtering __slots__ attributes having docstring at
filter_members(), this passes docstring captured at get_class_members()
to the filter_members() via ObjectMember.
Keep imports alphabetically sorted and their order homogeneous across
Python source files.
The isort project has more feature and is more active than the
flake8-import-order plugin.
Most issues caught were simply import ordering from the same module.
Where imports were purposefully placed out of order, tag with
isort:skip.
In #7651, autodoc stops to undecorate the functions on getting the
signature from the callables. But some kinds of decorators conceals
the correct signature because they pass through their arguments via
`(*args, **kwargs)`.
This restarts to undecorate the functions again as before #7651.
