    Status: Open => Answered

Jan Stránský proposed the following answer:
> They use .def() with all the parameters then ... staticmethod

all the parameters is not important, I think it is there for python docstrings and default parameters, you can use just
.def("pythonMethodName", &VsmPhys::someMethod)
.staticmethod("pythonMethodName")

> They use .def() ... then the declaration of staticmethod

it is not declaration, just conversion to Python. The
&VsmPhys::someMethod has to be declared in the class before, like
"static Real funcG(...)" in CpmPhys

> so how should i modify this ...
> I hope this is clear enough

sorry, I did not get the point :-)

specifically for CpmPhys::funcG, have a look how it is:
- declared in .hpp file [1]
- exposed to python [2,3] (as mentioned before, py::arg stuff is not needed)
- defined in .cpp file [4]
- used in Law2::go [5]

is that what you were asking?

cheers
Jan
