我们有一个 pybind11 模块，并希望使用 Jedi 为其类和功能完成代码。我们的方法是设置__doc__函数的文档字符串，以便 Jedi 可以使用它们来完成。当我们调用时，completions()我们得到一个空列表。Jedi 没有打印错误，也不是通过 set_debug_function。

我们在传递给 Jedi 的字符串中设置模块的路径。模块的导入也包含在此字符串中。

我们需要做什么才能让 Jedi 自动完成自定义 C++ 库类和函数？这通常可以使用__doc__吗？如果可以，格式应该是什么样的？

更新：感谢戴夫的评论，我们能够进一步分析问题。下面是一个例子：

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set_debug_function()是 Jedi 0.14.0 完成的输出bb.：

为什么绝地不返回对象实例的完成bb？dir(bb)在 shell 中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： 绝地解释器能够完成我们的对象：

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：

对象的自动完成适用于 jedi 0.11.1，但不适用于 0.14.0。我们假设在以后的版本中出现了问题。
