[yantaozhao]

Current problem

pyreverse output uml with class member names sorted.

Desired solution

do not sort class member names

Additional context

No response

I feel like this is a very subjective thing if sorting is desired or not. So I would like to vote for this:

🚀 keep the sorting
🎉 don't sort, use the order of definition from source code

[Pierre-Sassoulas]

Maybe another possibility would be to add an option to be able to do both ?

Agree. It would be better to add an option to let the user decide.

For additional context: Completely removing the sorting would also be problematic for the existing unit tests, as they require deterministic output.

[nickdrozd]

Testing requires deterministic output, but not alphabetical sorting. Sorting by code order would be just as testable. Obtaining that order will be a little trickier, depending on the existing sources of nondeterminism (sets, dictionaries, etc).

Sorting by code order will require some work on somebody's part (somebody other than me, because I don't care either way 😎).
