Any example of cpp2 calling c++ code?

[felixf4xu]

for example, if I have a c++ class, how can I initialize the class (new ?) and then call its member functions in cpp2?

Welcome!

A class is a class regardless which syntax is used to author it. So you just use it as usual, though new is now a function call rather than a built-in language feature.

See in particular: hello, world! and objects, initialization, and memory.

Thanks for the link of the document.

and I also found a perfect example code at https://github.com/hsutter/cppfront/blob/main/regression-tests/mixed-type-safety-1.cpp2

where Circle is a cpp1 class

class Shape { public: virtual ~Shape() { } };
class Circle : public Shape { };

and then

c := new<Circle>();     // safe by construction

here new<>() is a cpp2 template function and it's transcompiled into some kind of std::make_unique in cpp1.
