Match case for class items support

[Dennis]

Hello, I've refactored a little bit my code and found out that pyarmor is not supporting match case with class items. (I'm on pro version)

That's the error:

patterns may only match literals and attribute lookups

from enum import Enum, auto

class ExampleEnum(Enum):
    OPTION_A = auto()
    OPTION_B = auto()
    OPTION_C = auto()

def example_function(value: ExampleEnum):
    match value:
        case ExampleEnum.OPTION_A:
            # perform action
        case ExampleEnum.OPTION_B:
            # perform action
        case ExampleEnum.OPTION_C:
            # perform action
        case _:
            # default action

What's the reason for that? Will that be supported in the future?
Thanks, Dennis

Can't be reproduced. What I got by Pyarmor 8.5.7 with Python 3.10 in Darwin:

...
class pyarmor__1(pyarmor__6):
    pyarmor__2 = pyarmor__7()
    pyarmor__3 = pyarmor__7()
    pyarmor__4 = pyarmor__7()

def pyarmor__5(value: pyarmor__1):
    match value:
        case pyarmor__1.pyarmor__2:
            pass
        case pyarmor__1.pyarmor__3:
            pass
        case pyarmor__1.pyarmor__4:
            pass
        case _:
            pass

Try to clean local configuration path mv .pyarmor .pyarmor.bak and test it again.

Hello!
I found out that it's related to: --obf-code 2

pyarmor -d gen -O dist test.py --obf-code 2 where test.py contains the code above

INFO obfuscating file test.py
DEBUG process inline marker
DEBUG parse script
DEBUG process co
DEBUG process attribute
DEBUG unknown error, please check pyarmor.error.log
ERROR patterns may only match literals and attribute lookups
ERROR somthing is wrong

Also there is a typo in somEthing :)
