[Question] Getting class of object on which completion was requested

[nishikantparmariam]

Hi, I am developing tab completion feature for a Python library and have found jedi to be quite useful. My use case is to detect the class name of the object on which completion was requested. Is there a clean way to achieve this? I could find below workaround, here the goal is to find that x is of type Z.

from jedi import Interpreter

class Z:
    def foo(self): pass

code = """
x = Z()
x.
"""

interpreter = Interpreter(code, [locals()])
completions = interpreter.complete(line=3, column=2)
foo = completions[0].full_name  # completion for function foo, full name is '__main__.Z.foo'
class_name = '.'.join(foo.split('.')[:-1])
class_name

Thanks!

Does completions[0].parent().full_name work for you?

Thanks for the reply!! Yes, this works.

But, actually I was looking for a way to this without calling interpreter.complete. I would like to explain my use-case a bit more -

I want to show custom completions only on objects which are of a certain class (say Z in this case), I want to determine statically if x is of type Z - the workaround I am using is putting a method foo on Z and checking if foo comes when I complete x.. This doesn't scale well though. Happy to know if there some solutions around this in jedi.

I don't understand, sorry.
