Re: sizeof a ref object type

[jyapayne]

You can do what you want at compile time with a macro like so:
    
    
    import macros
    
    macro msizeof(obj: typedesc): untyped =
      let ty = obj.getType()
      
      var sym: NimNode
      
      if ty[1].kind == nnkBracketExpr:
        # This is a ref object
        sym = ty[1][1]
      else:
        # This is a normal object
        sym = ty[1]
      
      result = quote do:
        sizeof(`sym`)
    
    type
        MyObject = object
            a : int
            b : int
            c : int
        
        MyRefObject = ref object
            a : int
            b : int
            c : int
    
    echo msizeof(MyObject) # Prints 24
    echo msizeof(MyRefObject) # Also prints 24
    
    
    Run
