[SOLVED] static/class method in micropython?

Post by shawwwn » Tue Sep 11, 2018 6:31 am

Judging from the source, currently class method in micropython is not supported.
The underlying C struct of mp class instance only has .locals_dict.

Any plans to add support for class or static method?
This feature would be really useful for module developers.

Thanks.

Actually class methods (assuming you mean methods inside a class decorated with @classmethod) are supported. Look at the mp_type_classmethod type.

Nice. Thanks for pointing that out.

I am finding a way to implement static method in a python class written in C.
Any ideas how it can be done?

Nvm. I found it.

Inside py/obj.h,
there is a macro called

Code: Select all

MP_DEFINE_CONST_STATICMETHOD_OBJ
which puts a staticmethod wrap onto a function.

Thanks for the help!
I'm closing this issue.
