Comment(by SimonKing):
Leif and/or Volker, what happends if you do the following? Do you get
essentially the same as I? In particular, can the file be found?
{{{
sage: cython_code = ['cpdef test_meth(self,x):',
... ' "some doc for a wrapped cython method"',
... ' return -x',
... 'from sage.all import cached_method',
... 'from sage.structure.parent cimport Parent',
... 'cdef class MyClass(Parent):',
... ' wrapped_method =
cached_method(test_meth,name="wrapped_method")']
sage: cython('\n'.join(cython_code))
sage: O = MyClass()
sage: from sage.misc.sageinspect import sage_getfile, sage_getargspec
sage: sage_getargspec(O.wrapped_method)
ArgSpec(args=['self', 'x'], varargs=None, keywords=None, defaults=None)
sage: sage_getfile(O.wrapped_method)
'/mnt/local/king/SAGE/debug/sage-4.7.2.alpha3-prerelease/devel/sage/_mnt_local_king__sage_temp_mpc622_4939_tmp_1_spyx_0.pyx'
}}}
Does `O.wrapped_method?` and `O.wrapped_method??` work for you, or is it
impossible to open the source file? If the latter is the case: What is
`O.wrapped_method.__module__`?
I suppose that the problem is actually located in
`_sage_getdoc_unformatted`, because for me it already returns the file and
embedding information:
{{{
from sage.misc.sageinspect import _sage_getdoc_unformatted
sage: _sage_getdoc_unformatted(O.wrapped_method)
'File: _mnt_local_king__sage_temp_mpc622_4939_tmp_1_spyx_0.pyx (starting
at line 6)\nsome doc for a wrapped cython method'
}}}
