In SageMath 9.0, I have got an AttributeError when generating a ReST table
of methods of a class with a classmethod using `gen_rest_table_index`:
sage: class foo(SageObject):
....: @classmethod
....: def bar(cls):
....: pass
....:
sage: gen_rest_table_index(foo)
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-13-292c8c0bbbb0> in <module>()
----> 1 gen_rest_table_index(foo)
/zvol/sage/sage-9.0/x86_64/local/lib/python3.7/site-packages/sage/misc/
rest_index_of_methods.py in gen_rest_table_index(obj, names, sort,
only_local_functions)
174 if inspect.ismethod(e):
175 link = ":meth:`~{module}.{cls}.{func}`".format(
--> 176 module=e.im_class.__module__, cls=e.im_class.
__name__,
177 func=fname(e))
178 elif not PY2 and inspect.isfunction(e) and inspect.isclass(
obj):
AttributeError: 'function' object has no attribute 'im_class'
It works fine if there is no classmethod:
sage: class foo2(SageObject):
....: def bar(self):
....: pass
....:
sage: gen_rest_table_index(foo2)
'.. csv-table::\n :class: contentstable\n :widths: 30, 70\n :delim:
@\n\n :meth:`~__main__.foo2.bar` @ NO DOCSTRING\n'
I guess the problem is that `im_class` is not available in Python 3, am I
right?
