我们有一个pybind11模块，希望Jedi为其类和功能提供代码完成。我们的方法是设置函数的文档字符串__doc__，以便Jedi可以使用它们来完成功能。当我们调用completions()时，我们得到一个空列表。绝地不会打印错误，也不会通过set_debug_function打印。
我们在传递给Jedi的字符串中设置模块的路径。此字符串中还包括模块的导入。
要让Jedi自动完成自定义C ++库类和函数，我们需要做什么？通常使用__doc__可以正常工作吗？如果可以，格式应该是什么样？
更新：由于Dave的评论，我们得以进一步分析问题。下面是一个示例：
import bitbuffer
bb = bitbuffer.BitBuffer(100)
bitbuffer. # completion works for the module
bitBuffer.BitBuffer. # completion works for the class
bb. # completion does not work for the instance of the class
以下是Jedi 0.14.0的set_debug_function()输出，用于完成bb.：

Jedi为什么不返回对象实例bb的完成？外壳程序中的dir(bb)可以工作并生成以下输出：
['__bool__', '__class__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__len__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'capacity', 'clear', 'copy', 'data', 'desc', 'fill', 'from_int', 'marks', 'name', 'offset', 'pack', 'shadow', 'size', 'unpack']
更新＃2提示： 绝地解释员能够完成我们的目标：
script = jedi.Interpreter("bb.", [locals()])
script.completions() # this works
我们得出结论，对象本身没有问题。
更新＃3：
对象的自动完成功能适用于jedi 0.11.1，但不适用于0.14.0。我们假定更高版本中有问题。
