  hello, i want use urho3d. for this, i need create class with functions. i made it

  {.emit:"class MyApp:public Application{public:MyApp(Context* context):Application(context){}virtual void Setup();virtual void Start();virtual void Stop();};".}
  proc Start{.codegenDecl:"$# MyApp::$#$#",exportc.}=discard
  proc Stop{.codegenDecl:"$# MyApp::$#$#",exportc.}=discard
  proc Setup{.codegenDecl:"$# MyApp::$#$#",exportc.}=discard
  Run

  it works, but it is inconvenient. its better create macro class, like this https://nim-by-example.github.io/macros/, and use it. but i dont know, how create macro class i need, to use urho3d. pls, help me!

  There's no easy answer, but you can do it yourself without a huge amount of work. Check out this blog post on writing nim macros and use the dumpAstGen macro to show you how to make what you want. Happy learning!
