Outliner no alerting if functions or classes are doubled

[ManPython]

Type: Bug

Behaviour

There is misunderstanding witch functions is called when debugging.

Steps to reproduce:

create class

class Bike:
    name = ""
    gear = 0

# create objects of class
bike1 = Bike()
bike1 = Bike() # doubled

Hi! Could you clarify a bit more the expected and actual behavior?

[ManPython]

I never know that in code if long have more this same names (python don't care this).

microsoft/vscode#49925 (comment)

I always confused that collapsed tree of outliner is again opened and user must collapse, find right class and the functions inside if big file.

Regarding microsoft/vscode#240961 it's depend refactoring names, find duplication (should be duplicated on red color and maybe counter (1), (2), etc..), etc. or see real structure in relation to other similar classes or chat GPT.

[eleanorjboyd]

So are you expecting something in the UI to warn you that there are two things called bike1?

[ManPython]

Yes, or just list this same in elements list in outliner (Then more easy to find similar code parts, it can be case where was paste part far from current [eg. not only double paste], as wrong place, etc.). Soo red color for font, counter how many duplicated bike1(3) - eg

$${\color{red}bike1(3)}$$ $${\color{black}bike2}$$ $${\color{black}bike3}$$ $${\color{black}bike4}$$ $${\color{red}bike1(3)}$$ $${\color{red}bike1(3)}$$ $${\color{black}bike5}$$ $${\color{red}bike1(3)}$$

Can you clarify what you mean by "outliner"? A screenshot might be helpful.

[ManPython]

Code outline?

Yes, or just list this same in elements list in outline...

There's only one bike1 variable in your example above. The first bike1 = Bike() statement declares the bike1 variable and the second bike1 = Bike() statement is an assignment to the existing bike1 variable.

The Outline pane only shows declarations, not assignments. So the fact that bike1 only appears there once with your example code above is by design. Showing all assignments would introduce a lot of noise into the Outline pane.

Reassigning existing variables is a very common thing. And even assigning the same value to the same variable in multiple places is not unusual -- for example, assigning None to a "result" variable in multiple places within a function when handling error cases.

The feature you're requesting seems like it would be more appropriate for a linter rather than a language server and type checker. I'm going to move it to our enhancements discussions area though and if we get enough up-votes on it we will reconsider.

[debonte]

Seems like there's a problem with GitHub's "Convert to discussion" feature at the moment. I'll move this later.

@debonte
You are wrong, debuger on outline allow user to have in code this same parts code, and this is problem.
#6992 (comment)

Can you provide a real-world example that shows the issue that you're talking about?

[debonte]

Closing in favor of #7003.
